New Mexico Research Activities

Terrestrial research in the Southwest 2020

Research at the New Mexico Cooperative Fish and Wildlife Research Unit is geared toward providing practical solutions that are transferable to our Cooperators (New Mexico Department of Game and Fish, U.S. Fish and Wildlife Service, and New Mexico State University) and other agencies. Unit scientists and affiliated staff meet with resource professionals to discuss management needs. If the Unit cannot provide the expertise to develop and solve management needs, then we engage University faculty, staff and a network of professional colleagues to offer solutions. The Unit scientists address resource issues throughout the arid southwest that span from the southern Rockies to the Chihuahua and Sonoran ecosystems. Research areas of special emphasis include environmental stressors and native fish restoration and management, resource selection and population ecology of game birds and large mammals.

Landscape genetic structure of the western continental golden eagle population	July 2019	Studies of golden eagle mortality linked to wind energy facilities are cause for concern especially when coupled with the knowledge that golden eagles move great distances between breeding and wintering areas. Thus, mortalities that occur at a particular wind energy facility may not only impact a local breeding population of golden eagles but could also impact breeding populations on a continent-wide scale. Understanding the movement ecology and landscape genetic structure of golden eagles in the western US would be critically important toward understanding the potential risks wind energy facilities pose to the continental population of golden eagles. This information is essential to understanding the distribution of breeding populations of eagles, the level of connectivity that exists among them and where individuals from these populations migrate to in the winter. Thus our objectives are to assess the relationship of western golden eagle populations using molecular genetic and stable isotope methods.

The goal of this project is to assess the landscape genetic structure of golden eagles in the U.S. in efforts to understand the distribution of breeding populations of eagles, the level of connectivity that exists among them and where individuals from these populations migrate to in the winter. This information will allow for more informed management of golden eagles on a continent-wide scale. This project is a collaboration with the US Fish and Wildlife Service and Department of Fish, Wildlife, and Conservation Ecology at New Mexico State University.

Evaluation of baseflow as climate stressors in Rio Grande cutthroat trout	February 2015	http://pubs.usgs.gov/of/2013/1051/	This study characterized the thermal regime in a number of Colorado and New Mexico streams that contain populations of Rio Grande cutthroat trout and had no previous record of continual temperature records. When compared to Colorado’s water temperature criteria (Cold Tier 1), a portion of these populations appeared to be at risk from elevated stream temperatures, as indicated by exceedance of both acute (17 - 22 percent) and chronic (2 to 9 percent) water quality metrics. Summer water temperature profiles recorded at sites within current Rio Grande cutthroat trout habitat indicated that although the majority of currently occupied conservation streams have temperatures that fall well below these biologically based acute and chronic thermal thresholds, several sites may be at or approaching water temperatures considered stressful to cutthroat trout. Further, water temperatures should be considered in decisions regarding the current and future thermal suitability of potential Rio Grande cutthroat trout restoration sites. Additionally, baseflow discharge sampling indicated that a majority of the sampled stream segments containing Rio Grande cutthroat trout have flows less than 1.0 cubic feet per second (cfs) in both 2010 (74 percent) and 2011 (77 percent). The relative drought sensitivity of these low baseflow streams containing Rio Grande cutthroat trout could be further evaluated to assess their probable sustainability under possible future drought conditions.
Evaluation of intermittency of stream flow in headwater streams for Rio Grande Cutthroat trout	December 2014	The Rio Grande cutthroat trout (Oncorhynchus clarki virginalis) is the southern-most subspecies of cutthroat trout in the Western U.S., endemic to the Rio Grande, Pecos, and Canadian River basins in Colorado and New Mexico (Behnke 2002). Historically the subspecies occupied over 10,000 km of streams in this region, but currently occupies less than 12% of its historical range (1,500 km) with as few as 120 remaining conservation populations (Alves et al. 2008). In 2008, O. c. virginalis was added to the Endangered Species Act Candidate List, and the potential negative effects of climate change on this subspecies were discussed in detail in the listing package and included concerns about both water temperature and low flow. To help resolve some of the uncertainty related to climate vulnerability of existing O. c. virginalis core conservation populations, our research group initiated a monitoring effort in 2010 to characterize both stream temperature regimes and baseflow hydrology within 40 core conservation populations. Importantly, our fall baseflow measurements revealed that more than 67% of O. c. virginalis study streams exhibited discharge levels less than 1.0 cubic feet per second (cfs), with one completely dry site (Figure 1a), despite an above-normal 2010 snowpack throughout the majority of the sub-species range. In 2011, the basin experienced moderate to severe drought-conditions during the early summer, however, late-season rains likely reduced the impact of those early drought conditions. In 2011, fall baseflow conditions were documented with similar percentage of low flow streams within an expanded subset of O. c. virginalis streams (Figure 1b). Importantly, because our baseflow measurements occur at a single point during the late fall, the flow conditions during the driest portions of 2011 went undocumented. Low snowpack and resultant potential for flow intermittency and low baseflows has a high likelihood of negatively affecting O. c. virginalis populations, as was observed in 2002 when several populations were extirpated by drought due to low snowpack during the previous winter (Japhet et al. 2007; Patten et al. 2007). The extent of negative impact of the 2002 drought is unknown, as only a small subset of O. c. virginalis core-conservation populations were visited immediately following the drought to evaluate its impact.

Feasibility Study for Native Fish Establishment in McKittrick Creek, Guadalupe Mountains National Park, Texas	September 2015	The goal of the proposed work will be to determine whether a self-sustaining population of Rio Grande cutthroat trout as well as other native fishes (e.g., Rio Grande chub Gila pandora and rainwater killifish Lucania parva) can be supported in McKittrick Creek, Guadalupe Mountains National Park, Texas. To accomplish this goal, a suite of biotic and abiotic information gaps must to be filled. The objectives of this effort will be to characterize fish and aquatic macroinvertebrate communities, document amphibian occurrence, and describe spatial and temporal changes in physical stream habitat and water quality throughout the McKittrick drainage.	The McKittrick drainage, located in Guadalupe Mountains National Park, was surveyed August and November 2013 to characterize fish and aquatic macroinvertebrates, document the presence of amphibian and spring snails, characterize stream morphometrics and mesohabitat, and obtain snapshots of water quality. This assessment was conducted to investigate the feasibility of McKittrick drainage to support a native fish assemblage. Surveys for fish, aquatic macroinvertebrates, spring snails, and stream morphometrics were conducted on the main stem of McKittrick Creek and South McKittrick Creek (a tributary to the main stem of McKittrick). A preliminary survey of North McKittrick (a second tributary to the main stem) revealed discontinuous but perennial areas that supported amphibians but no salmonids. Thus, a series of four study reaches were established throughout the main stem and South McKittrick representing a total of 2.8 km of perennial water. Density of rainbow trout Oncorhynchus mykiss averaged 3.6 fish/100 m2 (range: 0.6-7.7 fish/100 m2) across all perennial reaches with the highest densities (7.7 fish/100 m2) found in Reach 2, located above Pratt Cabin. Longear sunfish Lepomis megalotis were captured only in the South McKittrick Creek in Reaches 2 and 3, but generally in lower densities (Average: 4.0 fish/100 m2) than rainbow trout. Longear sunfish were also observed in North McKittrick Creek but no population assessments were conducted to assess their density. Habitat assessments were completed at three of four reaches (Reach 1, 2, and 4) to describe mesohabitat, substrate composition, and to establish permanent transects for future surveys. The lowermost reach (Reach 1) was significantly wider (average wetted width: 4.2 m) than the upper two reaches (average wetted width: 2.3 m) and had generally poorer fish habitat, likely due to travertine deposition which limited suitable benthic substrate for macroinvertebrate fauna and spawning habitat. Rio Grande leopard frog Lithobates berlandieri tadpoles, sub-adults, and adults were observed in all intermittent water bodies of North McKittrick Creek in August, but were not observed throughout the main stem of McKittrick Creek or South McKittrick Creek. Sorting and identification of aquatic macroinvertebrate samples is still on going, although observations during sampling indicated that overall density and biomass was low. Water quality monitoring (i.e., stream temperature) is also still ongoing and results will not be available until the winter of 2014 when data loggers will be retrieved and analyzed (resulting in one full year of stream temperatures). A second survey of fish, aquatic macroinvertebrates, and amphibians are planned for June 2014 to capture seasonal changes in amphibian species and benthic macroinvertebrate communities. The lack of stream temperature information precludes a complete evaluation of the suitability McKittrick drainage to support Rio Grande cutthroat trout. After completion of stream temperature analysis Fall of 2014, a complete assessment of the drainage will be provided to Guadalupe Mountains National Park and other interested parties.
Effects of piscicide Rotenone on native amphibians	December 2013	The objective of the study will be to determine the acute and chronic toxicity effects of plains leopard frog and Chiricahua leopard frog to toxicological effects of a piscicide (rotenone). The research entails characterizing toxicological effects of rotenone at concentrations that are environmentally relevant throughout early life history stages of two native amphibians because of the proximity of their habitat to areas targeted for removal of non-native fishes.	The Student's research will contribute to the limited knowledge of sub-lethal and long-term toxicity effects of a piscicide on native amphibians as well as provide relevant toxicity information if amphibians are present at the time of a rotenone application. The effects of rotenone will be pronounced in gill-breathing stages of amphibians because the site of toxic action of rotenone is within the mitochondria located within the gills. Gills offer a direct line of exposure to sites of toxic action due to the large surface area and very short diffusion distance of gill lamellae. Survival may be affected if metamorphosis is delayed or results in a premature departure from ponds. Rotenone may also inhibit mobility of tadpoles, thus potentially reducing their ability to escape from predators. Indirect effects of rotenone may also be seen long after exposure if rotenone suppresses detoxifying mechanisms and thus increase the vulnerability of tadpoles to disease. This would be manifested in population decline due to loss of entire year classes. The results are expected to have an impact on rotenone use in ponds and streams of New Mexico that would expand protective guidelines to include the Chiricahua leopard frog and the northern leopard frog (Lithobates pipiens), for which rotenone effects are currently unknown. Differences in geographic distributions may also represent different toxicity responses to rotenone between the plains and the Chiricahua leopard frog emphasizing an urgent need for the description of lethal concentration ranges and sub-lethal effects of fish removal to diminish or avoid negative effects to native amphibian populations. My work will provide fishery managers with the window of when applications of rotenone would reduce collateral damage of the pesticide on non-target amphibian species.
Resource selection and movements of mule deer and elk on the Jemez Pueblo	March 2017	The goals project are to: 1) describe seasonal movements of deer and elk including delineating summer/winter ranges, fawning/calving areas, and migration routes; 2) estimate population size, survival rates, and determine cause of mortality for mule deer and elk on pueblo land and compare survival rates and cause-specific mortality with mule deer and elk collared in areas adjacent to the Pueblo of Jemez; 3) estimate forage availability for mule deer and elk in relation to wildfire and forest restoration treatments (e.g.,prescribed burning and thinning); and 4) assess resource selection patterns of mule deer and elk in relation to forest restoration and wildfire in association with an ongoing CFLRP large mammal monitoring project being led by the NM-CRU.	Forest restoration treatments have become more common in an attempt to improve wildlife habitat and to mitigate the risk of catastrophic wildfires, but little is known regarding the effects of forest restoration and habitat treatments on mule deer and elk populations. Landscape-scale forest restoration treatments are occurring in the Jemez Mountains, New Mexico primarily through the use of prescribed burning and forest thinning. Our objectives were to: 1) describe seasonal ranges and migration routes for mule deer and elk; 2) conduct aerial surveys and determine cause of mortality; 3) estimate forage availability across vegetation types and treatments; and 4) assess resource selection patterns of mule deer and elk in relation to forest restoration and wildfires. <br><br>• We observed relatively few elk on the Jemez Pueblo during any of the aerial surveys, most of which were on the West Unit in the Sierra Nacimiento. Mule deer were predominantly observed on the East Unit in the Cañada de Cochiti. Mule deer were more common than elk on the pueblo but were not particularly abundant. <br><br>• Herbaceous forage biomass was greater in wildfire burned areas than prescribed burns, forest thinning, and untreated areas.<br><br>• Oak forage biomass was greater in wildfire burned areas compared to prescribed burns, forest thinning, and untreated areas. Thinned areas tended to have higher oak forage biomass than untreated areas for most vegetation types.<br><br>• Mountain lion predation was the primary cause of mortality for mule deer and mountain lion predation and hunter harvests were the primary causes of mortality for elk. <br><br>• Mule deer selected for areas burned by prescribed fire and avoided wildfire burned and thinned areas less than 5 years old. Mule deer strongly selected for thinned areas >5 years old. At both spatial scales, grasslands were avoided during all seasons, pinyon-juniper woodlands were selected for in winter, and oak vegetation was selected during summer. Mixed conifer forests were selected during summer. <br><br>• Elk selected for wildfire burned areas and forest thinning. Elk selection of prescribed burns varied by season and year. When compared to ponderosa pine forests, elk selected for aspen, grasslands, and oak vegetation. Mixed conifer forests were selected for during spring, summer, and autumn and avoided in winter

Habitat selection, survival and cause-specific mortality of translocated mule deer in southern New Mexico	June 2015	In efforts to restore mule deer populations in New Mexico, the New Mexico Department of Game and Fish (NMDGF) will begin a translocation effort in 2012. Mule deer will be captured from high density populations and translocated to areas with lower mule deer abundance than expected based on habitat assessments. At least 100 mule deer will be captured and translocated into two areas with 50 being released in each area during the winters of 2012-13 and 2013-14. Half of the mule deer will be hard-released and the other half will be placed in a soft-release pen for 30 days perior to release. Approximately 80 mule deer will be fitted with radio collars to monitor survival and habitat selection.

Using a metapopulation analysis and risk assessment to improve consevation of the Sacramento Mountains Checkerspot Butterfly, a Species of Greatest Conservation Need	May 2013	The student, Rachel Ryan, developed novel genetic markers and has applied these in metapopulation theory to guide management decisions that focus on which populations of the butterfly are at the greatest risk of extirpation. A portion of her work has shown that local inbreeding is the result of a series of droughts (2006 and 2011) and that inbreeding is reducing the fitness of these populations by reducing colonization behavior. The arid southwest has begun to experience the effects of a warming climate. Thus, her research has also focused on identifying suitable habitat to facilitate adaptation of the subspecies to climate change.	None
Population dynamics and reintroduction characteristics of Mexican wolves in Arizona and New Mexico’s Blue Range Wolf Recovery Area	September 2015	The Blue Range population of Mexican wolves, although successfully established in1998, is not thriving. Between 1998 and 2003 the actual minimum population of Mexican wolves in the BRWRA closely tracked with population projections in the 1996 Final Environmental Impact Statement. From 2004 through 2010, the minimum population count has not reached FEIS projections or shown continued steady growth. Over the last seven years, the population size has hovered around the halfway point of the population target of at least 100 wolves. Yet, data from the reintroduction project has not been rigorously analyzed to help elucidate potential modifications for the project or describe best management practices for this population. In addition, the Mexican wolf project is currently developing a new recovery plan for the Mexican wolves, which will likely require additional reintroductions to occur for recovery objectives to be met. Scientific analysis of the data should help guide future reintroduction efforts in other areas and allow for comparison with disparate populations to further our understanding of Mexican wolf biology across their range.<br><br>The objectives of this study are to investigate: (1) habitat colonization preferences of Mexican wolves and the distribution of preferred wolf habitat across the southwestern U.S., (2) factors that promote successful initial releases and translocations of Mexican wolves, (3) factors that contribute to increased reproduction rates, (4) survival of Mexican wolves, and (5) dispersal patterns of Mexican wolves. Ultimately these factors will be incorporated into a population model to determine scenarios that increase or decrease population vigor.

Influence of livestock grazing on activity budgets and foraging efficiency of desert bighorn sheep	May 2014	Recent population growth has prompted the New Mexico Department of Game and Fish to petition for the removal of desert bighorn sheep (Ovis canadensis mexicana) from the state’s threatened and endangered species list. To more effectively manage desert bighorn sheep as a game species, the NMDGF has identified the need to assess the potential impacts of cattle grazing on forage resources and the subsequent influence on foraging ecology of desert bighorn sheep in New Mexico. PROJECT GOALS 1) Compare seasonal biomass of preferred forage species for desert bighorn sheep in areas with and without livestock grazing. 2) Estimate seasonal activity budgets of desert bighorn sheep in areas with and without livestock grazing. 3) Compare foraging efficiency of desert bighorn sheep in areas with and without livestock grazing. 4)Continue ongoing monitoring efforts that are currently being conducted by independent contractors to document and determine causes of mortalities of adult bighorn sheep fitted with radio collars in the Caballo and San Andres Mountains.

Growth and survival of Apache trout Oncorhynchus Apache under static and fluctuating temperature regimes typical of Southwestern streams:	December 2011	Increased stream temperatures through global climate change and urbanization will have important implications for fishes worldwide. While there is some information on the effects of elevated water temperatures on Apache trout Oncorhynchus Apache, less is known about effects of increased and fluctuating water temperatures over extended time periods, typical of Southwestern desert streams. Therefore, we applied static and fluctuating temperature regimes to determine how each affected the growth and survival of Apache trout. Using a recirculating water system, we tested static temperatures of 16, 19, 22, 25, and 28°C, temperatures that fluctuated +3°C from 16, 19, 22 and 25°C, as well as temperatures that fluctuated +6°C from 19 and 22°C. After a 14 day acclimation at 16°C, 12 days of temperature ramping and 30 day test trials, we determined the LT50 as well as mean growth for each temperature treatment. Results showed the LT50 for Apache trout under static conditions to be 22.9°C, 23.4°C under +3°C fluctuations and 22.9°C under + 6°C fluctuations. Growth decreased as temperatures approached the LT50. When comparing static conditions with fluctuating conditions with the same midpoint, growth was less under fluctuating conditions than under static conditions if the temperature fluctuation approached the thermal limit (CTMax). Reduced survival of individual fish, inhibited growth and changes in fish behavior caused by prolonged increased stream temperature will further affect the plight of the species. Therefore temperature tolerance information is critical to those restoring streams for Apache trout and in identifying new stocking locations.

Does thermal tolerance of fish vary by life stage?	December 2012	We evaluated upper temperature tolerances by life stage (fry-adult) of rainbow trout Oncorhychus mykiss (41-200 mm total length [TL] ); Rio Grande cutthroat troutOncorhynchus clarki virginalis (36-181mm TL), Apache trout Oncorhynchus apache (40-220 mm TL), largemouth bass(Micropterus salmoides (72-266 mm TL), Nile tilapia Oreochromis niloticus (35-206 mm TL) and channel catfish Ictalurus punctatus using critical thermal (CT) tests. Salmonids were acclimated at 18°C for 14 d, while the tilapia, largemouth bass and channel catfish were acclimated at 25°C for 14 d, CTMaxes then obtained, and data plotted and analyzed using simple linear regression. The results showed no significant difference (P > 0.05) in thermal tolerance between life stages for Nile tilapia, channel catfish, rainbow trout, largemouth bass and Apache trout. There was a significant difference (P < 0.001) in thermal tolerance between life stages of Rio Grande cutthroat trout, however the difference was less than 1°C across all live stages. Upper temperature tolerance of different life stages did not differ among the size groups tested in this wide variety of freshwater fishes. Therefore, management and research decisions based on upper thermal tolerance for one size group would be applicable to other size groups within ranges tested.

Determining the Limiting Factors of Pecos Bluntnose Shiner in the Farmlands Reach of the Pecos River	September 2014	The goal of the proposed project will be to identify conservation needs for the Pecos bluntnose shiner. Conservation needs for the species can be met if restoration efforts and habitat improvements are focused on ameliorating limiting factors for the threatened shiner.	Our study objectives are to (1) characterize the spatial and temporal relationship between water quality (i.e., salinity, conductance, dissolved oxygen, temperature) and discharge throughout the Pecos bluntnose shiner’s current range, (2) determine Pecos bluntnose shiner salinity tolerances and effects within several life history stages (i.e., hatching success in eggs, survival and growth of early proto-larvae (24 h post-hatch) and juveniles (45 – 90 days post-hatch), and (3) identify migration patterns of juveniles Pecos bluntnose shiner within the Farmlands Reach. By characterizing limiting factors that affect species abundance and distribution, recovery efforts can be directed toward expanding suitable habitat for Pecos bluntnose shiner within the Pecos River.
Responses of large mammals to forest restoration treatments and wildfire in the southwest Jemez Mountains, New Mexico	August 2025	Decades of fire suppression, overgrazing, and logging in the western U.S. have resulted in increased tree densities, altered habitat conditions for many wildlife species, and increased risk of stand-replacing wildfires. Land managers are currently implementing landscape-scale treatments in efforts to mitigate catastrophic wildfires and to restore historical forest conditions. The goals of this project are to monitor the responses of mule deer, elk, black bear, and mountain lion to forest restoration treatments and wildfires as part of the Southwest Jemez Mountains Collaborative Forest Restoration Project. Specifically, we are assessing changes in forage conditions, movements, and resource selection of mule deer, elk, black bear and mountain lion in relation to prescribed fires, restoration thinning, and previous wildfires. The results of this project will allow for more informed design and implementation of restoration treatments that simultaneously mitigate wildfire risk and enhance habitat conditions for mule deer, elk, black bears and mountain lions. This research is in collaboration between the New Mexico Cooperative Fish and Wildlife Research Unit, Department of Natural Resources Management at Texas Tech University, National Park Service, U.S. Forest Service, Jemez Pueblo, and New Mexico Department of Game and Fish.

Relationship Between Fish Size and Thermal Tolerance	September 2011	Using critical thermal maximum tests (CTMax), we examined the relationship between upper temperature tolerances and fish size (fry-adult/subadult lengths) of rainbow trout Oncorhynchus mykiss (41-200 mm total length [TL]); Apache trout O. gilae apache (40-220 mm TL); largemouth bass Micropterus salmoides (72-266 mm TL); Nile tilapia Oreochromis niloticus (35-206 mm TL); channel catfish Ictalurus punctatus (62-264 mm TL) and Rio Grande cutthroat trout O. clarki virginalis (36-181mm TL). Rainbow trout and Apache trout were acclimated at 18°C; Rio Grande cutthroat trout were acclimated at 14°C; and Nile tilapia, largemouth bass and channel catfish were acclimated at 25°C, all for 14 d. Critical thermal maximum temperatures (CTMax) were estimated and data was analyzed using simple linear regression. There was no significant relationship (P > 0.05) between thermal tolerance and length for Nile tilapia (P = 0.33), channel catfish (P = 0.55), rainbow trout (P = 0.76), or largemouth bass (P = 0.93) for the length ranges we tested. There was a significant negative relationship between thermal tolerance and length for Rio Grande cutthroat trout (R2 = 0.412, P < 0.001), and Apache trout (R2 = 0.1374, P = 0.028); however, the difference was less than 1°C across all lengths of Apache trout tested and about 1.3°C across all lengths of Rio Grande cutthroat trout tested. Because there was either no, or at most, a slight relationship between upper thermal tolerance and size; management and research decisions based on upper thermal tolerance should be similar for the range of sizes within each species we tested. However, the different sizes we tested only encompassed life stages ranging from fry to adult/sub-adult so thermal tolerance of eggs, alevins and larger adults should also be considered before making management decisions affecting an entire species.

Survival and cause-specific mortality of neonatal desert bighorn sheep in New Mexico	May 2014	Based on recent population growth due to active recovery efforts conducted by the New Mexico Department of Game and Fish (NMDGF), desert bighorn sheep (Ovis canadensis mexicana) have been removed from the state’s threatened and endangered species list. As a result of this delisting, desert bighorn sheep populations will be subjected to increased harvest in New Mexico. The NMDGF has identified the need to obtain estimates of lamb survival, recruitment and cause-specific mortality as part of ongoing efforts to manage for the continued growth of bighorn sheep populations in New Mexico. Our objectives are to: 1) estimate lamb survival and determine cause-specific mortality of neonatal desert bighorn sheep in the Peloncillo Mountains, New Mexico; and 2) continue ongoing monitoring efforts to determine causes of mortalities of adult bighorn sheep in the Peloncillo, Big Hatchet and Little Hatchet mountains.

Distribution and habitat selection/space use of migratory and resident golden eagles (Aquila chrysaetos) in areas with high potential for wind energy development in New Mexico	December 2016	Our overarching goal is to assess the risk that proposed wind energy developments might have on resident and migratory golden eagles in southeastern and south-central New Mexico and help develop mitigation strategies that will reduce impact. To accomplish this goal, we seek to: 1). Assess habitat and space use of migratory and resident golden eagles in areas managed by the Bureau of Land Management (BLM) with a focus on areas with a high potential for wind energy development in southeastern and south-central New Mexico. 2). Identify nest sites and estimate productivity and survival of golden eagles on BLM managed lands in areas with a high potential for wind energy development in southeastern and south-central New Mexico. 3). Determine phylogeographic patterns of relatedness for resident and wintering golden eagles in southeastern and south-central New Mexico. 4). Identify the origin and migration patterns for golden eagles over-wintering in southeastern and south-central New Mexico.	None

Conservation genomics of Pecos pupfish	August 2026	Pecos pupfish populations in New Mexico inhabit small, isolated, saline springs and gypsum sinkholes in the Chihuahuan Desert that are characterized by extreme temperature & salinity gradients. This species has suffered declines in distribution and abundance due to habitat degradation and hybridization with the non-native sheepshead minnow. We will characterize the population structure (e.g., history of gene flow, metrics of genetic diversity & inbreeding), explore evidence of natural selection & local adaptation, and investigate potential hybridization with sheepshead minnow. Inferences from these analyses will help guide future translocation efforts and guide development of a genetic monitoring program. This project is a collaborative effort with the New Mexico Department of Fish & Wildlife and the University of Montana.	None
Identifying barriers to pronghorn habitat connectivity in southwestern New Mexico in relation to rangeland management and renewable energy development	September 2028	The landscapes necessary to maintain large mammal movements are becoming increasingly fragmented across the western United States due to anthropogenic factors. These conditions in the broader landscape may influence the functional connectivity and impede the ability of wild ungulates to cope with changes in habitat and forage conditions associated with changing climatic conditions and anthropogenic activities, which may ultimately compromise sustainability of many big game populations. The NM CRU is currently working with the Bureau of Land Management to study pronghorn movements and habitat use in southern New Mexico. This project will assist the Bureau of Land Management and other cooperators (e.g., New Mexico Department of Game and Fish (NMDGF); NM Department of Transportation) with developing potential mitigation strategies to address impediments to pronghorn movements, increasing landscape connectivity and will identify important seasonal pronghorn habitat to inform future and current planning for renewable energy facilities and infrastructure.

Predicting climate change induced habitat shifts for big game species in New Mexico	December 2026	Climate change is the largest threat to ecosystem stability and the sustainability of wildlife populations. Worldwide, animals and plants are either migrating higher in elevation or northward where habitat connectivity exists or declining toward local extinction when isolated. Locally, changes in climate pose an imminent threat to game species, engendering serious ramifications for the sustainability of New Mexico’s vibrant hunting culture and associated economy. Despite the severity of this issue, there is not a clear understanding of where and when climatic changes can be expected to impact game species in New Mexico. Our project focuses on faunal relationships with habitat and projecting these relationships over time and geographical space given downscaled climate models and emission scenarios. Understanding how climate-induced shifts in ecosystem conditions will influence the future distribution of the big game species is critical to the development of long-term management plans by state and federal agencies. This project proposes to estimate resource selection and density of select big game species (e.g., elk, mule deer, oryx, pronghorn) in several study areas located in representative ecoregions of New Mexico. We plan to fit several populations of each species with GPS collars to assess resource selection as well as establish remote camera arrays to estimate density and abundance in each study area. Bioclimatic models will ultimately be used to predict changes in the distribution of major vegetation types and these data will then be combined with data on habitat selection and use, and population abundance/density to predict future distribution of the study species. The New Mexico Cooperative Fish and Wildlife Research Unit is engaged in this collaborative research effort with US Fish and Wildlife Service, New Mexico Department of Game and Fish, University of New Mexico, and Department of Defense.

Decision support tools to guide environmental flows and habitat management in the middle Rio Grande River	September 2028	Water is a limited resource in the desert southwest, in which agencies are tasked with allocating water for multiple purposes such as agriculture, residential use, and environmental flows. Climate change is expected to further exacerbate this issue in the Middle Rio Grande River, which creates conservation challenges for aquatic species. The Rio Grande Silvery Minnow is a federally endangered fish species. Given the competing demands for water, managers must allocate water for maximal benefit, often under uncertain hydrograph conditions) and identify creative solutions for population recovery, such as creation of nursery habitat. The project is a collaboration of researchers across multiple agencies and includes the US Bureau of Reclamation and the U.S. Fish and Wildlife Service. A useful decision-making model will be developed to inform water, habitat, and conservation management decisions on the Rio Grande River to benefit the Rio Grande Silvery Minnow population.	None
Development of a brown trout GT-seq panel for native fish conservation purposes	June 2025	PI Pregler will coordinate among the development of a GT-seq (genotyping-in-thousands by sequencing) genetic marker panel to support future YY-brown trout implementation efforts. Non-native trout species like brown trout can outcompete native New Mexico fish species. The introduction of hatchery male brown trout with YY genotypes to natural populations can shift sex ratios with the eventual goal of decreasing & eradicating non-native brown trout populations in locations where recovery of native species is needed. The developed genetic panel will be used to determine the sex ratio in natural populations to assess the progress of such interventions. This project is supported and funded by New Mexico Department of Game of Fish and is a collaborative effort among three genetics labs: (1) USFWS Abernathy Fish Technology Center (Seattle, WA), (2) Floragenex (Beaverton, OR) and (3) GT-Seek (Twin Falls, ID).

Evaluation of a Gila trout outcrossing experiment	June 2029	Gila trout are one of the rarest trout species in North America and exist in remnant habitats in the rugged wilderness of Gila National Forest where they persist in only 11 percent of their historical distribution (Propst et al., 2021). Maintenance of genetic diversity is a fundamental component of this species’ recovery plan in which higher genetic diversity is important for adaptive potential as well as alleviating inbreeding risks. Therefore, in 2020, the New Mexico Department of Game & Fish translocated the five lineages of Gila trout together into multiple sites to increase genetic diversity and fitness. A fin clip was taken from every fish translocated into the watershed for future genetic analysis. Enough time has passed since the initial translocation effort in 2020 that these translocated individuals have had the opportunity to reproduce in Whitewater. This marks an important point in the study to assess various fitness outcomes of the translocation effort. Specifically, we aim to use genetic analysis of translocated fish and their offspring to characterize the mating structure and reproductive success. These results will show whether individual lineages or hybrids are more successful and will allow us to directly investigate if outcrossing Gila trout lineages is a viable conservation strategy to improve their fitness. This project is supported and funded by the New Mexico Department of Game & Fish and may also involve collaborators from other universities and federal agencies.	None
Development of invasive plant species for Chihuahuan Desert Network	December 2010	The Chihuahuan Desert Inventory and Monitoring Network (CHDN) is one of thirty-two networks in the National Park Service charged with developing long-term natural resource monitoring plans for their park units. The CHDN is made up of seven national parks, monuments, recreation areas and historic sites in New Mexico and Texas. The invasion of non-native and exotic plant species is challenging protection and management of resources in National Parks throughout the United States. Ecological and system effects depend on the rate and amount of spread, site characteristics, and the biology of organisms in infected areas. Although initial establishment of non-native plants species can result in increased bio-diversity, prolonged occupancy by non-native species can disrupt user interactions and communities, and ultimately lead to a less diverse biota. This research will provide information to help in understanding the introduction, spread, and distribution of non-native species and their effects on native habitats. Identification of distributional pathways and estimating the exposure of biotic resources to invasive species through risk assessment approaches, provide the framework for developing conservation strategies to restrict or eradicate invasive species.

Southwest Regional GAP Analysis: Application, Outreach and Education	May 2011	The Southwest Regional Gap Analysis Project was a successful multi-state project in Arizona, Colorado, Nevada, New Mexico, and Utah. The effort mapped land cover, 819 terrestrial vertebrate species, and land stewardship over the 5-state region. With the completion of the project, there was a need to assist in applying the data to land managers needs such as the Comprehensive Wildlife Conservation Strategies. Our objectives will be to provide assistance to state wildlife agencies in the application of the SWReGAP data to support their conservation efforts. This project will compare state-identified species of greatest conservation need with species identified as gap species, and describeconservation areas across the entire southwest.	None
Influence of invasive plants and dune encroachment on White Sands pupfish and burrowing owls on Holloman Airforce Base	September 2011	Two species potentially affected by invasive plants on Holloman Airforce Base in the arid Tularosa Basin of New Mexico are the White Sands pupfish (Cyprinodon tularosa) and the western burrowing owl (Athene cunicularia hypugae). White Sands pupfish are federally listed as a species of concern and state listed as threatened in New Mexico (USFWS, http://www.fws.gov/endangered/wildlife.html; BISON-M, http://www.bison-m.org). The western burrowing owl is also federally listed as a species of concern (USFWS, http://www.fws.gov/endangered/wildlife.html) and is listed as a species of greatest conservation need in the New Mexico Comprehensive Conservation Wildlife Strategy (New Mexico Department of Game and Fish 2006). The goal of this research is to characterize the effects of invasive plant species and dune encroachment on these imperiled species.	None
Pronghorn productivity and resource selection in the Chihuahuan Desert	December 2012	A population of pronghorn on White Sands Missile Range (WSMR), in south-central New Mexico, has declined since 1980. While this decreasing trend has coincided with intermittent periods of severe drought, competition with the non-native South African gemsbok is presumed as a contributor to the overall decline of the population. Thus the goal of this study was to relate seasonal changes in forage quality throughout pronghorn habitat on WSMR and relate these seasonal changes to diet composition and nutrition and evaluate dietary overlap between pronghorn and gemsbok. Dietary quality (fecal nitrogen, FN and fecal 2,6-diamonphelic acid, FDAPA) reflected seasonal differences in available forage as well as severe drought. Average FN increased in pronghorn from 1.4% in the cool-dry season (2010) to 2.1% in the warm-dry (2010) season. In contrast, FN decreased in pronghorn from 2.1% in the warm-dry (2010) to 1.4% in the drought of the warm-dry season (2011). Diet composition revealed pronghorn consumed 75 species with forbs representing the major component in the diet (42-68%) in contrast to grasses (2-21%). Although gemsbok and pronghorn share the same habitat (were often seen grazing together), an analysis of dietary overlap between the two species revealed low (17%) to moderate (37%) overlap and suggests the gemsbok are not negatively influencing forage selection of pronghorn on WSMR. Gemsbok dietary quality did not differ between warm-dry (2010) and the drought of the warm-dry season of 2011, revealing resiliency in the gemsbok compared to the pronghorn during abnormally low precipitation periods.

Population Distribution and Genetic Assessment of Rio Grande Chub	June 2012	The goal of this study will be to define the genetic relatedness within and among Rio Grande chub populations throughout New Mexico, Southern Colorado, and Texas. We hypothesize a small effective population size (Ne) and fragmentation of populations of Rio Grande chub have resulted in reduced genetic diversity; and, the relatedness of populations will be directly related to connectivity among populations. From extant populations of Rio Grande chub among three drainage basins, we will use microsatellite markers to determine how gene flow is affected by distance among basins and degree of connectivity among populations within basins. The results of this research can be used to guide decisions in supplementing or establishing new Rio Grande chub populations and identify which populations serve as a source for genetic material for future translocations. I anticipate this work will provide information that can be used by fisheries managers on federal and state lands in the development of a conservation plan for the species. Historical surveys of the species distribution began during the reporting period.	Rio Grande chub Gila pandora is found throughout the Rio Grande, Pecos, and Canadian basins of Colorado, New Mexico and Texas. The species is state-listed in Colorado as threatened and managed through a captive propagation program throughout its northern range. In New Mexico, the Rio Grande chub is listed as a species of greatest conservation need and is state-listed as sensitive due to habitat alterations and competition with non-native fishes. Characterizing the patterns of genetic structure and diversity of populations of Rio Grande chub will assist with its conservation in New Mexico by providing a baseline of genetic variation throughout its range. In the event of a catastrophic loss due to fire or drought, these populations could be reestablished from others with comparable genetic structure. In this study, the genetic relatedness within and among Rio Grande chub populations throughout New Mexico, was characterized using a suite of 11 microsatellites loci among 15 populations in three basins. All 11 microsatellites originated from cross-amplification of microsatellites developed for other cyprinids (bonytail chub Sacramento splittail, Sacramento pikeminnow, tui chub). From the sequenced data, Rio Grande chub exhibited 2 - 27 alleles per locus, average observed heterozygosity ranged from 0.71 to 0.87, and average expected heterozygosity ranged from 0.75 to 0.85. Average inbreeding coefficient (FIS) was 0.021 across all loci among the 15 populations. A significant level of genetic differentiation among subpopulations compared to the total population was observed with an FST of 0.080. There was a relationship between spatial distance and genetic relatedness of populations throughout New Mexico as evidenced by greater relatedness among populations within watersheds or stream connectivity. Furthermore, genetic relatedness was directly associated with fragmented or isolated populations. The observed patterns of genetic diversity among populations of Rio Grande chub can be used to ensure genetic diversity is maintained by identifying source populations and improving migration through habitat improvement to enhance long term viability and reduce the chance for local extinctions. This study emphasizes the importance of establishing a genetic inventory of a species before it is imperiled requiring state or federal intervention.
Effects of thermal tolerance limits on the distribution of southwest native fishes	August 2011	This is a joint research project with the Arizona Cooperative Fish and Wildlife Research Unit (Dr. Scott Bonar).

Restoration of Rio Grande cutthroat trout to the Mescalero Apache Reservation	October 2013	Over the past twenty years, the Mescalero Apache Tribe has managed a series of watersheds on the Mescalero Indian Reservation as a native trout fishery, accepting accounts that a pure strain of RGCT existed. This was to serve as a RGCT broodstock source, however recent studies revealed cutthroat trout in this drainage were not a pure strain. Sources of pure Pecos strain can be obtained from the New Mexico Department of Fish and Game. The Mescalero Tribe has agreed to restore the watersheds within their tribal lands to serve as refugia for the Pecos strain. The Tribe and its Council has agreed to partner with U.S. Geological Survey, New Mexico Cooperative Fish and Wildlife Research Unit, New Mexico State University, U.S. Fish and Wildlife Service, and the NMGFD to meet mutually shared goals of restoring and maintaining a RGCT within its historic range. The importance of developing effective and meaningful partnerships with agencies and non-profit organizations that share mutual goals while respecting Tribal sovereignty cannot be overstated. The long term value of this partnership will not only provide habitat benefits and protection for RGCT, but will build trust and management capacity for the species as well.	Throughout western North America, stream salmonids are experiencing declines due to hydrologic modifications, non-native fish introductions, and habitat degradation. Additionally, climate change is expected to impact salmonids through increases in stream temperatures and alterations to the hydrologic cycle. The goal of this research was to describe the relationship among habitat limitations and margins of energetic profitability for a Rainbow Trout Oncorhynchus mykiss population in a high elevation, headwater stream. To reach this goal, the objectives were to 1) describe habitat use and selection of Rainbow Trout of varying size classes across varying seasons (temperatures), 2) assess the bioenergetics of microhabitat use and availability and habitat suitability across varying climate change scenarios, and 3) characterize summer and winter behavioral thermoregulation of Rainbow Trout in a small headwater stream. Habitat use and availability was assessed monthly for one year within the Middle Fork Rio Ruidoso, Mescalero Apache Reservation, New Mexico. Data from microhabitat use and availability was linked to environmental variables of macroinvertebrate drift and temperature using a foraging-based bioenergetic model. Fish displayed a strong selection of stream positions that were close to cover during the winter, likely to minimize metabolic costs and risk of predation. Fish of all size classes selected deeper average depths (34.5 cm) and slower average focal velocities (average 1.0 cm•s-1) than available. Due to the large capture area from greater depths and minimal swimming costs from slow velocities, bioenergetic model predictions indicate that 81% of all fish met maintenance rations and 40% maximized their growth. Bioenergetic model predictions of winter net energy intake rates (NEI) were generally positive and infers greater chances at survival, while more than 80% of energy was predicted to be acquired for age-1+ fish during the months of May, June, and September indicating the majority of growth occurred during these three months. Additionally, when climate change scenarios were modeled with a 6°C increase for summer and winter months, the amount of available habitat capable of supporting Rainbow Trout was predicted to be reduced by as much as 12% during the summer and 17% during the winter. Mean NEI rates were also predicted to decline by 67-75% over the summer while NEI would increase over the winter. Fish tagged with radio telemetry devices and archival temperature loggers revealed that fish made frequent, but short (2-4 h) use of coolwater refugia that was as much as 3°C cooler than ambient temperatures during the summer. Mean differences in prolonged coolwater refugia use differed by 0.16°C from ambient stream temperatures during the summer. During the winter, fish also made periodic use of warmwater refugia to escape supercooled waters while mean warmwater refugia use differed by 0.04°C. Results from this study can be used to guide managers in future restoration and management of small headwater streams, particularly in arid-land systems where discharge and velocities are relatively low throughout the year compared to larger streams in the intermountain west. Stream restoration efforts should focus on creating deep, pool habitat with abundant cover for overwintering fish. This research also demonstrated the importance of protecting areas of thermal refugia as these areas can reduce the metabolic costs associated with rising temperatures and protect fish from supercooled waters.

Identification of factors limiting mule deer populations in the White Sands Missile Range San Andres National Wildlife Refuge area with emphasis on effects of chronic wasting disease and risks associated with chronic wasting disease	December 2009	Mule deer have declined to remnant status in large areas of the Tularosa Basin, San Andres Mountains, and adjacent areas in southern New Mexico. Reasons for the declines are unknown; thus, effective population recovery strategies cannot be developed. Moreover, chronic wasting disease (CWD) was recently diagnosed in populations in these areas, which injects several novel questions into recovery issues. First, what are the risks associated with recovering mule deer populations in infected areas in terms of spreading CWD to adjacent populations? Second, does CWD have a population-level effect on either mortality or productivity that would mitigate recovery efforts? Further, can CWD be managed in an infected population to allow both recovery and control of CWD? Currently, effective management options are lacking for control of chronic wasting disease (CWD) in free-ranging populations; control strategies currently employed by management agencies have either been ineffective in halting the spread of CWD or have not been evaluated for success. Inherent to the lack of effective management options is a lack of understanding of the role, process, and impacts of CWD in free-ranging deer populations; each of these is important to understanding the risk associated with CWD and the level (and type) of management necessary to address the risk. Thus, this project will concurrently evaluate the effectiveness of disease management strategies, develop critical information of the epizootiology of CWD to allow identification and development of new strategies, and determine mule deer population dynamics, habitat relations, and factors currently limiting populations in Chihuahuan desert habitats. The goal of this project is to characterize population dynamics and habitat relations of mule deer in the WSMR-SANWR complex, to determine which factors are limiting current mule deer populations and what risks CWD may pose for recovery of mule deer populations in this area. Encapsulated within this overall goal are subgoals of developing and evaluating the efficacy of control measures associated with CWD. Specific objectives associated with these goals include: 1. Determine prevalence of CWD in mule deer on WSMR/SANWR and in adjacent areas (San Andres Mountains). 2. Determine survival and cause-specific mortality of mule deer in WSMR/SANWR and adjacent populations 3. Determine mule deer health and condition and its influence on pregnancy, fawn production, and survival. 4. Determine production and survival of fawns in study populations. 5. Determine movement patterns and population exchange of mule deer on WSMR/SANWR and adjacent populations. 6. Determine past and current habitat characteristics and quality in terms of the ability of the landscape to support and produce mule deer. 7. Determine whether occurrence of CWD is localized (associated primarily with a specific geographic area and a specific matrilineal band) or generalized (likely direct; occurring throughout infected populations and across social group bounds) in the population. 8.

Modeling raptor population status, trends, and take rates	December 2026	Evaluating sustainable take rates for raptor species, primarily bald and golden eagles, is necessary to inform incidental take permits issued by the U.S. Fish and Wildlife Service to proposed and existing wind-energy facilities. The take rates are informed by predictive models that incorporate species vital rates (e.g., survival), environmental effects, and anthropogenic hazards (e.g., wind turbines). The project focuses on developing models that inform incidental take permits, and also improve the models themselves to better reflect predicted changes in climate.

Developing an evaluation framework to inform NPS coastal infrastructure investment decisions	August 2023	Ongoing climate change, sea level rise, and more powerful storm systems will cause increasing damage and loss of facilities in coastal units of the National Park Service over the coming decades. Over time, sea level rise, storms, and funding limits will defy the National Park Service’s ability to maintain all existing coastal park infrastructure in suitable conditions in all locations. This project developed a transparent analytical framework and process that identified and incorporated comprehensive evaluation criteria that can be used across all National Park Service coastal park units to support decisions for capital investments in infrastructure of coastal national park units considering the projections of sea level rise and associated hazards (e.g. storms, erosion).

Decision support for sustainable raptor take limits in a changing climate	March 2026	Climate change already affects raptor populations, through impacts on migration biology and vital rates. However, the decision framework in use by the U.S. Fish & Wildlife Service (Service) to estimate population trends and set allowable take limits from anthropogenic activities is static with respect to climate. Given that climate change is already impacting raptors, assumptions of stationarity for vital rates are increasingly unrealistic and cast doubt on predictions of flyway-scale allowable take derived from existing frameworks. We are developing a new decision support tool that explicitly includes climate variables as inputs to population dynamic models to allow the Service to set allowable take limits that are more biologically realistic over the timeframe of interest. In addition to benefiting the Service, establishing take limits based on a more comprehensive set of climatic conditions will guide other stakeholders (e.g., state natural resource agencies and tribal leadership) in making more informed decisions regarding allowable take and mitigation measures to offset anthropogenic take within their jurisdictions. To ensure transferability of decision tools, we have invited representatives from relevant stakeholder groups to participate in framing the decision problem, parameterizing models, and evaluating alternative management strategies.

Habitat Modeling and Disease Risk Assessment for Rocky Mountain Bighorn Sheep on the Jicarilla Apache Nation	December 2024	Bighorn sheep are culturally significant to the Jicarilla Apache people. Through history, bighorn sheep were found and hunted throughout the higher elevations of the Jicarilla Apache’s ancestral range. An opportunity to consider the potential of introducing bighorn sheep to Jicarilla Apache Nation lands has seemingly been created by a series of wildfires. The NM CRU is assisting with modeling potential habitat and evaluating risk of contact with domestic sheep and goats to assess disease risk potential for Rocky Mountain bighorn sheep.

Evaluating landscape permeability and connectivity for pronghorn in southwestern New Mexico	December 2025	The landscapes necessary to maintain large mammal movements are becoming increasingly fragmented across the western United States due to anthropogenic factors. These conditions in the broader landscape may influence the functional connectivity and impede the ability of wild ungulates to cope with changes in habitat and forage conditions associated with changing climatic conditions, and anthropogenic activities, which may ultimately compromise sustainability of many big game populations. Adaptive movements by non-migratory populations allow animals to efficiently exploit dynamic nutritional landscape. These movements are critical for migratory and non-migratory populations alike as they allow them to maximize nutritional gain, enhance survival and recruitment, and increase probability of population persistence. This will be especially important for populations in arid and semi-arid regions that are predicted to become hotter and drier under various climate change models. Pronghorn in the arid Southwest are generally nomadic rather than seasonal migrants. However, impediments to movements that allow pronghorn to track changing forage conditions in an arid landscape are equally important for population persistence as migration routes are to truly migratory populations in more north temperate regions. This project will monitor pronghorn movements in southwestern New Mexico for a period of 2-3 years. The goals are to monitor space use and movements, identify impediments or barriers to movement that can be targeted by management agencies for remediation, and assess habitat use patterns to determine habitat utilization, with a particular emphasis on vegetation restoration treatments implemented by BLM.	The landscapes necessary to maintain large mammal movements are becoming increasingly fragmented across the western United States due to anthropogenic factors. These conditions in the broader landscape may influence the functional connectivity and impede the ability of wild ungulates to cope with changes in habitat and forage conditions associated with changing climatic conditions, and anthropogenic activities, which may ultimately compromise sustainability of many big game populations. Funding provided to state and federal agencies from Secretarial Order 3362 (Improving Habitat Quality in Western Big Game Winter Range and Migration Corridors) has contributed to substantial efforts to identify, map and monitor big game migration routes across the western United States. Yet many big game populations are non-migratory, characterized by resident or nomadic movement strategies. These resident and nomadic populations characterize the majority of mule deer and pronghorn populations across the lower elevation and more arid portions of the southwestern U.S. Mapping efforts for these populations are largely not covered by funding from Secretarial Order 3362, resulting in a gap in the knowledge of animal movements and distribution needed to make informed land management decisions. This project will monitor pronghorn movements in southwestern New Mexico for a period of 2-3 years.

Waterfowl Habitat Selection in Arid Landscapes	December 2025	Wetlands and riparian areas represent less than 2% of land cover in the southwestern United States and are expected to decline with the onset of climate change. Wetlands in this region are therefore exceptionally important to resident and migratory waterfowl and in turn, recreational hunters and ecotourism. The Mexican duck was only recently recognized as a separate species from the Mallard, and has been sparsely studied. Mallards are known to readily hybridize with closely-related species, therefore our study will identify habitat selection patterns in each species that may facilitate or discourage contact. The project is a collaboration of researchers from the U.S. Geological Survey, U.S. Fish and Wildlife Service, New Mexico State University, and the University of Texas at El Paso, in coordination with Ducks Unlimited. Our project will identify habitat features and management practices that are important for supporting waterfowl populations, to provide guidance on water management and support recreational opportunities for hunters.	Wetlands and riparian areas represent less than 2% of land cover in the southwestern United States; of this historic 2% more than 1/3 has been lost to agriculture and urbanization. Numerous migratory waterbirds use southwestern wetlands as energetic linkages between wetland habitats during migration and as important staging and wintering areas. However, the ephemeral nature and annual variability in timing and location limit the value of these resources to most species across the entirety of all life history events. The Mexican duck (<i>Anas platyrhynchos diazi</i>) has unique life history adaptations that allow the species to take advantage of these variable wetland conditions throughout their entire cycle. Our study will evaluate and habitat use patterns of Mexican ducks and other southwestern dabbling duck species to better understand habitat needs for waterfowl in a changing climate. This study is partnering with the U.S. Fish and Wildlife Service and the University of Texas at El Paso.
Evaluation of Cougar Predation and Bear Kleptoparasitism on Vermejo Park Ranch, New Mexico	June 2025	Over the last 15 years, in response to drought, declining range and riparian conditions, and projected drought conditions in the future, Vermejo Park Ranch (VPR; northern New Mexico) has made an effort to determine the carrying capacity for large ungulates (e.g., elk [<i>Cervus canadensis</i>] and American bison [<i>Bison bison</i>]) of the ranch during an average dry year. Understanding large predator populations and their role in regulating elk (and other ungulate) populations is an important, but relatively unexplored question at VPR.<br>Vermejo Park Ranch is home to black bears (<i>Ursus americanus</i>) and cougars (<i>Puma concolor</i>). Black bear predation can be a primary source of mortality on elk calves. Similarly, cougar predation can be a significant source of elk mortality. Black bears may benefit from, and negatively affect cougars, through kleptoparasitism of cougar kills, which may indirectly impact prey (ungulate) populations by increasing cougar kill rates to make up for the loss of food resources. The primary goal of this study is to document cougar prey selection on VPR and the influence of bear kleptoparasitism on frequency and volume of cougar prey. We anticipate this information will provide insights on the magnitude of elk and mule deer (<i>Odocoileus hemionus</i>) killed by cougars annually and inform future considerations of predator management to support the mission of VPR.

Resource selection and movements of mule deer and pronghorn: responses to Kermit overland conveyor	March 2026	BLM permitted a 16-mile overland conveyor system to transport sand for use in the oil fields in southeastern New Mexico. Given the potential for the conveyor to impede movements and home range utilization of wild ungulates, we are assessing the response of mule deer and pronghorn to construction and operation of the conveyor. Partners on this project include New Mexico Department of Game and Fish, Bureau of Land Management and Atlas Sand. By determining if there are any adverse impacts on movements, home range utilization or habitat selection of mule deer and pronghorn, we can contribute to development of mitigation efforts, as applicable.	The purpose of this project are to assess the responses of mule deer and pronghorn to construction activities and operation of Kermit Conveyor System in southeastern New Mexico.

Inferring Rosy-Finch demography and breeding distribution trends from long-term wintering data in New Mexico	December 2026	Alpine tundra biomes are expected to undergo massive changes in habitat structure and function under climate change. Many populations of summit-dwelling species have already been extirpated in recent years, because they are unable to migrate in elevation to escape warming temperatures or habitat loss. Rosy-finches are among the most climate-threatened species in North America and are notoriously difficult to study due to breeding in high elevation cliff habitats of alpine region, though during the winter they readily approach birdfeeders in a variety of habitats. Therefore, studying wintering populations may provide important clues as to the status, structure, and trends of breeding populations. This study is a collaboration between the U.S. Geological Survey, U.S. Fish and Wildlife Service Migratory Bird Management, New Mexico Department of Game and Fish and Rio Grande Bird Research, Inc. Our study will delineate connectivity among breeding areas and the southernmost wintering area in which Rosy-Finches occur, and identify long-term trends in survival and abundance. These data will help managers identify potential populations in need of conservation, and identify potential actions to support wintering populations.	The three Rosy-Finch species (Black, Brown-capped, and Gray-crowned) are among the most climate-threatened species in the United States. Rosy-Finches breed within high alpine and artic tundra biomes of North America, which are predicted to be disproportionately impacted by climate change. Therefore, identifying potential drivers of vital rates, abundance, and breeding distributions can potentially important environmental and habitat needs. Our study will evaluate long-term trends in demography and breeding distribution trends (inferred from stable isotopes) using long-term data form wintering birds captured on the Sandia Crest, New Mexico, which is also the southernmost point in which all three species co-occur. This project is a collaboration between the USGS New Mexico Cooperative Fish and Wildlife Research Unit, USFWS Migratory Bird Management, the New Mexico Department of Game and Fish, and Rio Grande Bird Research Inc. The research will be used to identify potential conservation actions, including habitat restoration, that could improve conditions for Rosy-Finches in a warming climate.
Identifying environmental and demographic drivers of American kestrel population declines to inform conservation actions	June 2024	American kestrels have been steadily declining across their North American range for several decades. Kestrels are primarily associated with open country and grasslands, and grassland birds are among the most rapidly declining avian groups in North America. Though kestrels are among the most heavily studied raptor species, previously published demographic analyses at local-scales have failed to identify potential causes of population declines. Thus, broad, continental-scale population analyses that use more available data sources may offer insights into causes of population declines that can inform conservation actions. This project is a collaboration of researchers across multiple agencies and includes the USGS New Mexico Cooperative Fish and Wildlife Research Unit, USFWS National Raptor Program, USFWS Migratory Bird Management Southwest Region, USFWS Migratory Birds, and the Cornell Lab of Ornithology. This research will be used to identify potential conservation actions that could address the causes of population declines identified by the population models. We will use decision analysis tools to then identify regional-scale research priorities that could test the effectiveness of conservation actions and further elucidate drivers of kestrel population dynamics.

Habitat Use and Survival of Reintroduced Juvenile Bolson Tortoises	May 2025	The Bolson tortoise is the largest and rarest of the six Gopherus species native to North America. With the exception of captive breeding populations in New Mexico, the Bolson tortoise has been extirpated from its U.S. range for over 12,000 years. In cooperation with the USFWS and the Turner Ecoagriculture Institute, this study will evaluate survival rates and habitat use of juvenile Bolson tortoises released on a large private ranch in southern New Mexico. The results from this study will be used to inform future reintroduction decisions within the species historic range in the Chihuahuan Desert.

White-tailed Ptarmigan Reintroduction Ecology	June 2024	The white-tailed ptarmigan is the smallest grouse species in North America and is endemic to alpine habitat. Despite reintroduction efforts in the 1980s, ptarmigan are now functionally extirpated from the southernmost portion of their historic range, located in northern New Mexico. Due to a lack of monitoring, the causes of extirpation remain unclear, and could be attributed to climate change, geographic isolation, or other unknown causes. This study will evaluate the demographic outcomes of a newly-reintroduced ptarmigan population from Colorado. The study will also compare habitat selection patterns as well as chick diet composition and growth rates with ptarmigan populations in Colorado. The information collected in this study will be central to informing future reintroduction efforts in both New Mexico and other portions of the species range where they are now extirpated (e.g. ,Wyoming), and guide management and conservation efforts of New Mexico Department of Game and Fish and the U.S. Fish and Wildlife in future species status assessments.	Climate change is predicted to contract the distribution of alpine species that are limited in their ability to disperse to suitable habitats. The white-tailed ptarmigan is an alpine-obligate species that is currently extirpated from portions of its historic range, including its southern periphery in northern New Mexico. Comparative ecological studies among core and periphery ptarmigan populations can identify habitat and foraging requirements. The project is a collaboration of researchers across multiple agencies and includes the New Mexico Department of Game and Fish, USFWS Science Applications, Colorado Parks and Wildlife, and USGS Fort Collins Science Center. Demographic parameters from newly-reintroduced ptarmigan in New Mexico (periphery) as well as comparative behavioral data from the reintroduced population and Colorado (core) will be used to evaluate long-term population viability and inform other potential reintroduction efforts throughout the ptarmigan’s range.
Effects of recreational disturbance on desert bighorn sheep in western Colorado	June 2025	Responses by large herbivores to human disturbance can result in a change in their habitat use, movements, and increased vigilance and decreased foraging time. Increased movements and reduced foraging time result in higher energetic costs and lower energetic gains, potentially decreasing fitness. The goal of this project is to determine potential impacts of increasing recreational activities on desert bighorn sheep in the Dominguez-Escalante National Conservation Area, Colorado and develop management recommendations as appropriate to mitigate negative effects of recreation on desert bighorn sheep herds. Partners on this project include Colorado Parks and Wildlife, Bureau of Land Management, Wild Sheep Foundation, Desert Bighorn Council, and Rocky Mountain Bighorn Society. Data analysis on behavioral responses and changes in habitat selection associated with recreational activities will allow CPW and BLM to develop management plans to mitigate negative effects of recreation on desert bighorn sheep herds.

Differential survival of two size classes of Rainbow Trout and the predatory impact of Northern Pike in a high elevation New Mexico reservoir	June 2022	The New Mexico Department of Game and Fish manages Rainbow Trout at Eagle Nest Lake for New Mexico citizens as a put, grow, and take fishery. Management objectives stipulate that 10 Rainbow Trout per hour of electrofishing with a size structure of 50% Rainbow Trout greater than 254 mm (10 in) total length. However, population surveys reported a decline in Rainbow Trout per hour of electrofishing that presumably coincided with the illegal introduction of Northern Pike into Eagle Nest Lake.<br>Our goal is to develop a Rainbow Trout stocking strategy for Eagle Nest Lake that meets the objectives for New Mexico's citizens to catch Rainbow Trout greater than 254 mm. We are evaluating the predator-prey relationship of Northern Pike and Rainbow Trout using a combination of stomach contents (i.e., diet) and stable isotopes of Northern Pike to assess whether Rainbow Trout represent a substantive part of Northern Pike diet, or, are a periodic part of the diet that occurs at the time of the Rainbow Trout stockings. Seasonal sample collections timed with stocking of Rainbow Trout will reveal the relative contribution of Rainbow Trout versus other fishes to the Northern Pike diet of Eagle Nest Lake. Ultimately, fish size (fingerling vs. sub-catchable), and season stocked can be adjusted to maximize survival and growth of Rainbow Trout for capture by New Mexico fishers.

Mapping Big Game Migration Corridors - New Mexico	July 2025	Recent research indicates that migration corridors are culturally transmitted from one generation of ungulates to the next. Thus without appropriate management, the continued persistence of these migratory populations could be threatened. To assist state and federal management agencies make informed decisions regarding conservation of migratory populations, the location of migration routes, stopovers, and seasonal ranges need to be identified and mapped. This work is being done in response to Secretarial Order 3362, and will assist the New Mexico Department of Game and Fish with mapping big game migration corridors, stopover locations and seasonal ranges across the state. Once mapped, these geospatial data will then be used to inform land and wildlife management plans in order to ensure the long-term persistence of these populations through conservation of their migratory routes, seasonal ranges and stopovers.

Identification and characterization of habitat conditions of mule deer, elk and pronghorn migration routes and stopover locations in northern New Mexico	December 2023	Migratory ungulate populations require distinct winter and summer ranges (and resources therein) to fulfill their life history characteristics, reproductive requirements, and to maintain adequate nutritional status allowing for population vital rates (e.g., adult and neonate survival) sufficient to prevent population declines. Our objectives are to identify and map seasonal ranges, migration routes, and stopover locations for mule deer, pronghorn, and elk in northern New Mexico allowing state and federal agencies to identify and mitigate potential threats to the persistence of these migration routes. Further, we are also assessing habitat characteristics along the migration route and at stopover locations to allow for more informed management of these migratory populations.

Habitat Suitability for Gila Chub Reintroduction in the Upper San Francisco River Drainage	December 2023	Gila chub (Gila robusta), a fish of greatest conservation need, has not been collected from the San Francisco River in New Mexico since 1948. The goal of federal and state management agencies is to replicate Gila Chub populations to ensure representation, resiliency, and redundancy by expanding GIla chub throughout its historical range. Our research will characterize whether the river has suitable habitat for eventual reintroduction of the species. We will work closely with our federal (USBOR, USFWS, USFS) and state (NMCFWRU and AZFW) partners to conduct a thorough habitat and hydrological assessment of the San Francisco River. Our research will be used to inform federal and state managers of the feasibility of a successful translocation of the fish species.

Modeling bald and golden eagle and other raptor populations and take rates	November 2023	The USFWS has scientifically evaluated sustainable take rates for both bald and golden eagles, established regional eagle management units (EMU) with population objectives, conducted surveys to estimate population sizes, and set annual take limits for each species of eagle in each EMU. For incidental take permits for wind energy facilities, the USFWS has developed a peer-reviewed collision risk model (CRM) to predict eagle take at proposed wind energy projects. The USFWS has also adopted a formal adaptive management process for updating the initial take estimates based on post-construction fatality monitoring data once the wind energy project becomes operational.	Eagle collisions with turbines at wind energy facilities is a common occurrence in some areas of the US. If wind turbine collision-related mortality rates are sufficiently high, it could compromise population growth rates and population persistence. We are assisting the USFWS with conducting demographic analyses using the collision risk model, and then updating estimates with fatality monitoring data. These results aid in the issuance of incidental take permits to operators of wind energy facilities. Additionally, the USFWS is seeking to improve the models it uses to predict fatalities, and to use the data collected under individual permits to formally update the overall modeling process. Further, the USFWS is interested in exploring how covariates that might influence eagle exposure or collision risk can be incorporated into the collision risk model to improve the accuracy of, and decrease the uncertainty around the estimates. This project is a collaboration between the USFWS, New Mexico Cooperative Fish and Wildlife Research Unit and the Department of Fish, Wildlife and Conservation Ecology at New Mexico State University.
Elk demography, movements and habitat selection in the Mexican Wolf Recovery Area in Arizona and New Mexico	June 2025	Elk population declines have been observed following wolf reintroduction or recolonization events. These declines were attributed to the combined effects of hunter harvest, predation and interactions with stochastic climatic events resulting lowered adult survival and recruitment. In addition, changes in the predator community composition has led to other non-lethal effects with the potential to influence elk demographic rates. Baseline data on elk survival rates, cause-specific mortality and habitat selection is limited for periods prior to the reintroduction of Mexican wolves in New Mexico and Arizona (e.g., Ballard et al. 2000). Consequently it is unknown whether Mexican wolves are reducing elk population growth or if wolf predation is compensatory, additive, or partially compensatory due to a lack of appropriate data. The lack of data impedes the development of the most informed management plans for elk in the Mexican wolf recovery area. Therefore the goal of this study is to assess variability in survival, cause-specific mortality, movements and habitat selection of elk across the Mexican wolf recovery area in Arizona and New Mexico. Our specific objectives are to: 1) estimate seasonal and annual cause-specific mortality rates for elk neonates and adult female elk; 2) estimate seasonal and annual survival rates for neonates and adult female elk; 3) estimate seasonal kill rates and prey composition of Mexican wolves; 4) assess effects of wolf activity on seasonal habitat selection and movements of elk; and 5) model the likely population trajectories of elk populations subjected to varying cause-specific mortality rates from predators (e.g., Mexican wolves, black bears, mountain lions, coyotes) and other causes of mortality (e.g., harvest, illegal harvest, vehicle collision).

This study is a collaboration between the New Mexico Cooperative Fish and Wildlife Research Unit, Arizona Game and Fish Department, New Mexico Department of Game and Fish, and the U.S. Fish and Wildlife Service.
Susceptibility of Rio Grande Cutthroat Trout to Displacement by Non-native Brown Trout: Implications for Future Management and Persistence of the Most Southern Subspecies of Cutthroat Trout in the Face of a Changing Climate	September 2019	Rio Grande Cutthroat Trout (RGCT; Oncorhynchus clarkii virginalis) is the New Mexico state fish, but habitat loss and non-native trout invasions threaten the persistence of the remaining 12% of the populations throughout its historic range. Understanding the relationship between temperature and non-native fish invasion for this southernmost subspecies of cutthroat trout will benefit all cutthroat subspecies as the climate continues to warm. We used a production framework to evaluate how temperature and competition with nonnative Brown Trout (Salmo trutta) impacted the ecological success of RGCT populations. We compared annual changes in production of RGCT populations and related these changes to the diets of RGCT in the presence and absence of Brown Trout across a temperature continuum. The rate at which a population collectively accumulates biomass is critical to population persistence because more biomass translates to increased reproductive capacity, increased competitive ability, and ultimately increased survival. We are working with a consortium of stakeholders that include two state agencies, eight federal agencies, two Tribal nations, three Pueblos, and three private groups. The project was funded by the U.S. Geological Survey, National and South Central Climate Adaptation Science Centers. Our results will be used by managers to identify and focus restoration efforts on streams with the greatest potential to support RGCT while maintaining an economical balance with a popular sportfish.

YY-Male Brook Trout as an Eradication Tool of Wild Brook Trout Populations in New Mexico	June 2022	Brook Trout (Salvelinus fontinalis), native to northeastern North America, share some of the same resource requirements as other salmonids that inhabit cold high elevation streams. The species has invaded the western U.S. and is extirpating native fishes, especially when in sympatry with native trout. In New Mexico, native Rio Grande Cutthroat Trout (RGCT; Oncorhynchus clarkii virginalis) has experienced a decline due to loss of habitat and competition from non-native trout. Viable removal options for non-native trout are currently limited to chemical piscicides and manual removal. Piscicides are effective but costly and non-species specific. Manual removal can be species specific, but with a low success rate. In light of these management needs, recent development of the Trojan male (hereafter, referred to as MYY, a male fish with two Y chromosomes) Brook Trout offers a species specific and cost-effective method of eradicating invasive Brook Trout. MYY can only produce male offspring and will theoretically drive the wild Brook Trout population to 100% males and eventual eradication.<br>The goal of the proposed work will be to shift sex ratios of selected populations of wild Brook Trout toward all male fish and eventual extirpation. These populations of Brook Trout are of interest because they coexist with populations of RGCT, which are of conservation value due to low introgression and protection on public and private lands. In addition, the trout populations inhabit relatively short distances of stream (1-7 km) with few tributaries and barriers to prevent recurring invasion of wild Brook Trout. Beginning in 2018, we introduced fingerling MYY Brook Trout and have conducted seasonal surveys to characterize survival and growth of the MYY Brook Trout. We are working closely with our State cooperator (New Mexico Department of Game and Fish), a private entity (Turner Enterprises), and the Santa Fe National Forest to assess the utility of using MYY as an effective and cost-effective management tool for future conservation efforts of native fishes.

Asian Tapeworm in an Endangered Southwestern Fish: Assessing Infections Using a Non-lethal Molecular Screening Tool.	July 2017	The federally endangered Humpback chub Gila cypha has experienced declines throughout its range due to loss of habitat and invasive fishes. However, optimal habitat within the Little Colorado River (LCR) represents an important stronghold for the largest remaining population of Humpback chub in the Colorado River basin. Unfortunately, temperatures in the LCR are also optimal for the proliferation of the invasive pathogenic Asian fish tapeworm Schyzocotyle acheilognathi. The current standard for positive identification of infection is necropsy and visual examination of the gut via microscopy, a methodology undesirable for assessing parasitic infection in endangered fishes. A novel species-specific primer targeting the cytochrome oxidase I subunit (COI) mtDNA gene region of Asian fish tapeworm was used in conjunction with swabbing of the anogenital pore as a convenient non-lethal sampling methodology to assess prevalence of infection in LCR Humpback chub. Acceptable primer sensitivity (52%) and specificity (79%) were demonstrated utilizing captive propagated Humpback Chub exposed to Asian fish tapeworm. Despite moderately-low sensitivity, the non-lethality of this methodology may offset decreased sensitivity, especially for monitoring in imperiled fish. Using the validated methodology, wild Humpback chub were screened for infections at two study reaches in the lower LCR spring and fall 2015. The infection prevalence for spring (includes all size classes) across study reaches was 19.5%. Infection prevalence in the fall sample was 6.2%. Infection frequency increased in juveniles and sub-adult fish (75-250 mm). However, infection frequency decreased in adult fish (250-400+ mm). Based on this evidence, juveniles and sub-adult Humpback chub (<200 mm) may be ideal targets for anthelminthic treatment. A combination of behavioral traits, including a predilection for feeding on zooplankton as juveniles and sub-adults and piscivory as larger adults may expose Humpback chub to Asian fish tapeworm infections at all stages in its life history. The molecular tool in conjunction with a swabbing methodology offers a time efficient, non-lethal method to detect infections in large numbers of fish within the hatchery environment and prevent continued transmission of the parasite into wild populations.

Gila National Forest Stream Temperature and Intermittency Monitoring Network for Species of Special Interest	December 2018	Management of imperiled fishes of greatest conservation need in the arid Southwest requires an understanding of their habitat. The importance of stream temperature is well recognized especially in light of a changing climate where there will be a major shift in temperature and precipitation in the 21st century. To this end, the 2016 WRRI Student Grant funded deployment of a stream temperature and intermittency-monitoring network in Willow Creek, Gila National Forest, New Mexico. Willow Creek is home to a population of Gila trout (Oncorhynchus gilae) that were once extirpated in the 2012 Whitewater-Baldy Wildfire. Preliminary data Willow Creek revealed a maximum seven-day weekly average temperature of 15.6°C. The maximum daily range increased from 11.28°C to 20.87°C. The maximum 2-hour average was 20.85°C. From the literature, the 7-day chronic sub-lethal temperature for Gila trout is 28.25°C. Thus, these temperatures throughout Willow Creek were not an immediate threat to Gila trout persistence in Willow Creek. Temperature data continues to be collected through the summer months when lowest flows occur. The implementation of this monitoring network will allow for further data collection and analysis of Willow Creek as a long-term recovery stream.

Impacts of Drought on Southwestern Cutthroat Trout: Influences of Changes in Discharge and Stream Temperature on the Persistence of Rio Grande Cutthroat Trout Populations	December 2019	We studied the impacts of drought and invasive trout on survival and productivity on Rio Grande cutthroat trout (<i>Oncorhynchus clarkii virginalis</i>, RGCT) populations. Rio Grande cutthroat trout is the southernmost subspecies of cutthroat trout and endemic to the Rio Grande, Canadian, and Pecos River basins of Colorado and New Mexico. The subspecies is reduced to less than 11% of its historic range with most populations occupying isolated high elevation headwater streams. One of the greatest threats to its survival is the effect that low stream flow due to drought will have on this coldwater trout living at the edge of its range. Our work provides insight into the current and future threats of RGCT populations under environmental and biological pressures. We investigated the effects of stream temperature, stream flow, and food resources has on reproduction, survival, population growth, and recruitment of young into the population. We developed population models using these effects to better understand the risks to RGCT persistence. Lastly, we explored the consequences of climate on RGCT population productivity through the characterization of the prey base. We found evidence that RGCT reached maturity fastest at sites with warm stream temperatures and low densities. We did not find a strong relationship between discharge and any demographic rate, although apparent survival of mature RGCT decreased as stream temperature increased. Our study suggests plasticity in trait expression may be a life-history characteristic which can assist trailing edge populations like RGCT to persist in a changing climate.	Rio Grande cutthroat trout (RGCT; Oncorhynchus clarkia virginalis) are the southernmost subspecies of cutthroat trout and currently occupy less than 12% of their historic range. Loss of habitat due to competition and hybridization with introduced trout and habitat alteration has restricted the remaining 122 populations to small (5.8 km median length) isolated habitat patches. A stream temperature and discharge monitoring program also identified that the majority of occupied habitat patches, while currently thermally suitable for the subspecies, have very low summer baseflows (< 1.0 cfs) which restrict fish movement and increases the risk of population extirpation due to stochastic disturbances (i.e., drought). We used otoliths and multistate capture-mark-recapture data collected along a temperature and stream drying gradient to assess life-history traits and persistence of RGCT. We found evidence that RGCT reached maturity fastest at sites with warm stream temperatures and low densities. We did not find a strong relationship between discharge and any demographic rate, although apparent survival of mature RGCT decreased as stream temperature increased.

Abundance and Habitat-related Use of White Sands Pupfish	November 2019	Small-bodied fishes represent a monitoring challenge when they are locally abundant, short-lived, and alter their reproductive strategy as environmental conditions vary. Use of minnow traps with an index of abundance (i.e., catch-per-unit-effort, CPUE) for White Sands pupfish (Cyprinodon tularosa) can be affected by basic methodological choices such as trap soak time (i.e., effort) as well as the timing and location of trap placement. Movement into and out of minnow traps by the pupfish affected CPUE. White Sands pupfish exited traps at frequencies that were nearly equivalent to the rate of entering, suggesting total catch and thereby CPUE, are strongly influenced by factors that determine the probability of an animal exiting the trap. In addition, CPUE was weakly correlated with a more robust estimate of abundance (Lincoln-Peterson estimator) suggesting CPUE is not a good index for abundance especially when trap soak times are variable.<br><br>Validation of Otolith Deposition in Laboratory and Field-reared White Sands Pupfish - Otolithic organs (earbones in fish) can be used to accurately evaluate the age of a fish. If otolith increments are deposited daily and time of hatch (onset) is known. <br><br>Reproductive Strategies of White Sands Pupfish inhabiting Stable versus Unstable Habitats - White Sands pupfish was used to test the hypothesis that mate choice strategies are influenced by environmental stability. Wild fish were collected from two locations each characterized by either highly variable flows marked by stream drying and extreme temperatures or stable flows with consistent diel patterns of water temperature. Detectable differences were observed between pupfish from stable versus unstable stream environments in both the distribution of eggs. Additionally, reproductive effort was detectably different between fish from stable versus unstable environments. These results suggests that reproductive investment may decrease as habitat stability decreases due to the breakdown of reliable reproductive signals.	Fish sampling in desert cienega systems are logistically challenging. The small size of the White Sands pupfish (Cyprinodon tularosa) adds to the monitoring challenge. While these fish are locally abundant, they are short-lived and can alter their reproductive strategy as environmental conditions vary. Use of minnow traps with an index of abundance (i.e., catch-per-unit-effort) for White Sands pupfish can be affected by basic methodological choices such as trap soak time (i.e., effort) as well as the timing and location of trap placement. We tested current sampling techniques to provide alternative methodologies to natural resource managers tasked to monitor the species. We worked with the Environmental Stewardship Branch of the Department of Army, White Sands Missile Range in New Mexico. Our research provided alternatives to the use of passive capture traps in characterizing White Sands pupfish populations throughout a desert cienega.
Natal Source and the Influence of Environmental Bottlenecks on Largemouth Bass Recruitment in Elephant Butte Reservoir	June 2019	Largemouth bass (Micropterus salmoides) is the most sought after sportfish in New Mexico. However, population abundance of largemouth bass in Elephant Butte Reservoir remains well below the statewide target objective of 20-40 fish/h. As such, Largemouth Bass fingerlings have been stocked into the Reservoir to augment the bass population. We were tasked to retrospectively characterize the contribution of stocked versus natal (hatched in the reservoir) Largemouth Bass to assess if stocking practices were successful. We used a non-lethal collection of dorsal spines in conjunction with strontium isotopes in the spines to characterize origin of fish and learned that stocking was successful. In addition, we identified rate of water level change within the reservoir affected spawning of the bass population. We partnered with our State cooperator (New Mexico Department of Game and Fish) to conduct the research. Our results will be used to make informed management decisions on the appropriate timing of stocking fingerling Largemouth Bass. Our results will also be used by water managers to time the delivery of water throughout the middle Rio Grande Basin to increase fish habitat for spawning in Elephant Butte Reservoir.

Influence of stream temperature, intermittency, and nonnative fishes on the current and future distribution of native fishes in the Gila and Mimbres drainages	December 2019	Stream temperature, flow, and the presence of non-native fishes can affect the distribution of native cold- and cool-water fishes. This is especially true for native fishes that have already experienced significant contractions in their historic range. The Gila and Mimbres drainages, located in southwestern New Mexico, support a unique cold- and cool-water native fish fauna adapted to the arid stream systems in which they evolved. These fishes, however, are losing ground to non-native fishes and to loss of habitat due to intermittency from stream drying. We implemented a temperature monitoring network throughout current and historical fish distributions to assess localized temperature effects on the distribution of the native fishes. We are working with the National Forest, U.S. Fish and Wildlife Service, New Mexico Department of Game and Fish, and citizen scientists to provide a comprehensive understanding of the dynamics that air and water temperature have on these arid-land fishes for future water planning needs.

Resilience Landscapes: Influence of fire and forest restoration on spatial and temporal distribution of fish and invertebrate communities	June 2020	The Las Conchas Fire began 26 June 2011 and spread at a rate of 26,000 acres per day burning 156,593 acres until fully contained 1 August 2011. At that time, the Las Conchas fire became the largest fire in New Mexico's history. In less than one week, one-third of the Valles Caldera National Preserve (VCNP) was burned. One month after the wildfire was fully contained, a series of rains resulted in exceptionally high flows and large ash input throughout streams on the Preserve. Fish surveys following the ash-laden flood events revealed a 95% reduction in trout abundance. The severity of the fire within the catchments of these streams resulted in variable flow and elevated sediment that have affected recovery of fish assemblages and the benthic macroinvertebrate community eight years post-fire. While density of adult brown trout have increased from less than 1.0 fish/100 m2 (August 2011) to 8.0-23.8 fish /100 m2 (May 2019), fish densities remain well below pre-burn densities (51-156 fish/100 m2). Recovery of native fish populations and the macroinvertebrate community assemblage on the VCNP are listed as priority needs for the National Park Service. The research will be used by Preserve biologists to make informed management decisions of the forested watershed and riparian areas of the streams.	IN 2011, the Las Conchas Fire became the largest wildfire in New Mexico. In less than one week, one-third of the Valles Caldera National Preserve (VCNP) was burned. The severity of the fire within the forested watershed of the streams resulted in variable flow and elevated sediment that has continued to affect recovery of fish assemblages and the benthic macroinvertebrate community eight-years post-fire. Recovery of the aquatic community on the VCNP is listed as a priority need by the National Park Service. Eight years post fire, monitoring has revealed continued suppression of the salmonid population compared to pre-fire with little to no fish recruitment in the burned areas. In addition, the aquatic benthic invertebrate community continues to experience variable diversity throughout the fire-affected streams of the VCNP, which suggests ecological recovery is ongoing eight years post-fire. The research will be used by Preserve biologists to make informed management decisions of the forested watershed and riparian areas of the streams.
Kirtland AFB mountain lion study	November 2019	Wildlife management on Department of Defense Lands is often hampered by a lack of data on specific wildlife species.

An assessment of the genetic structure of an urban Cooper's hawk population	September 2019	The U.S. Fish and Wildlife Service has been coordinating a study of the population ecology of an urban population of Cooper’s hawks (Accipiter cooperii) in Albuquerque, New Mexico since 2011, in collaboration with the New Mexico Department of Game and Fish and New Mexico State University. A major objective of the study is to develop a detailed understanding of the demography and population ecology of a model raptor population to obtain insights into the population ecology of harder to study species of management concern, such as golden eagles (Aquila chrysaetos). We now have rigorous empirical estimates of the number of occupied Cooper’s hawk nesting territories, reproductive success, survival rates, female dispersal, and spatially explicit estimates of prey density for each year of the study. We propose to undertake an analysis of genetic material and stable isotopes of feathers from the Albuquerque Cooper’s hawk study population to gain additional insights into their mating system, behavioral ecology, and population genetic structure. Important questions these analyses may help answer are: (1) what factors are associated with high rates of extra-pair paternity in Cooper’s hawks, and how those factors might affect individual fitness and population growth; (2) what is the frequency and potential source of immigrants into the Albuquerque study population; and (3) what is the phylogeographic relationship of this Cooper’s hawk population to others that have been genetically sampled. In addition, this study presents a valuable opportunity to compare and contrast genetic estimates of population attributes (e.g., estimates of paternity certainty and of effective population size) with direct measures obtained through banding and radio telemetry.

Estimation of mountain lion density in New Mexico	June 2020	The goal of this study is to provide relevant population and density data for mountain lions in New Mexico that will contribute to the management plans developed by the New Mexico Department of Game and Fish. The objectives of this study are to: 1) estimate mountain lion abundance and density in replicated survey areas across New Mexico to provide additional data for deriving harvest limits; 2) compare data-derived density estimates to those used in the habitat model currently employed by NMDGF to develop harvest limits; and 3) test a remote camera-based method for estimating mountain lion abundance and density in the absence of marked individuals.	Estimation of large carnivore population size and density at scales most relevant for management is arguably one of the most challenging issues in wildlife management. Despite substantial advances in methodological and analytical approaches for the estimation of common game species, estimation of low density predator populations remains challenging for state and federal management agencies. We are currently estimating the abundance of mountain lions in New Mexico in collaboration with the New Mexico Department of Game and Fish. This study will provide relevant, precise and unbiased population and density data for mountain lions in New Mexico that will drive harvest plans.
Population trajectories and extinction probabilities for populations of large ungulates	December 2018	Understanding the importance of life history parameters is vital to managing wildlife populations. We will evaluate the minimum population size at which a populations are unlikely to go extinct and the population persistence times of various ungulate species across the Southwest in relation to variation in observed demographic rates. The intent is to generate population models using a suite of observed demographic parameters (and their variability), thereby assisting in management of multiple ungulate species across the southwestern United States.	Understanding the importance of life history parameters is vital to managing wildlife populations. In collaboration with the U.S. Fish and Wildlife Service, we are evaluating the minimum population size, optimal demographic characteristics (e.g., survival, recruitment), and release strategies (e.g., number of animals and translocation schedules) that balance population growth and persistence for both target and source populations involved in translocation efforts. Furthermore, through our modeling efforts, we are also evaluating the effects of recurring droughts and various predator management strategies on the trajectories of translocated populations. Many translocation efforts fail to achieve management objectives, frequently due to a failure to fully consider demographic, management and climatic contexts in which the translocations are implemented. This work will inform wildlife management agencies on translocation strategies that are most likely to lead to population persistence of both source and target populations involved in these translocation efforts.
Predation rates and use of habitats and wildlife drinkers by mountain lions	July 2020	For decades, State and Federal wildlife management agencies have built and supplied man-made water sources within desert landscapes, making surface water a consistent and stable feature. However, some have speculated that the provision of surface water could be counterproductive for management because it may: 1) lure ungulates from preferable areas (such as escape terrain) thereby increasing their risk of predation; 2) predators may linger near water sources to increase their chances of killing a visiting ungulate; and 3) water sources may make areas previously inhospitable for carnivores hospitable, exacerbating losses in ungulates. Thus by providing surface water to increase ungulate populations, it may attract predators (and prey), thereby increasing kills on ungulate species. The goals of this project are to evaluate the effect that wildlife drinkers have on mountain lion habitat selection and to determine if mountain lion kills are disproportionately located near man-made perennial water sources. The project is a collaborative effort between the New Mexico Cooperative Fish and Wildlife Research Unit, Armendaris Ranch, U.S. Fish and Wildlife Service, New Mexico Department of Game and Fish, and Arizona Game and Fish Department.	Wildlife management agencies maintain man-made water sources for wildlife in arid environments based on long-held assumptions that it benefits wildlife and does not have adverse consequences. However, some have speculated that these water sources may allow predators to occupy areas that would otherwise be inhospitable and that predators use these water sources to ambush prey, thus increasing predation on species that these water developments are intended to benefit. In collaboration with the U.S. Fish and Wildlife Service, New Mexico Department of Game and Fish and Arizona Game and Fish Department we are determining the effect of man-made water sources on mountain lion habitat and prey selection and if kill sites of ungulates are disproportionately located near man-made water sources (i.e., waters are used as ambush sites). The results of this study could have impacts on wildlife water development programs across the West. Furthermore, this project will greatly expand our knowledge on large carnivore water dependency and the influence of water on predator space use, resource selection and predator-prey dynamics in arid ecosystems.
An estimate of abundance and an assessment of the efficacy of sterilization techniques for the control of wild burro populations	March 2018	Feral burro populations have increased in numbers and are impacting fragile desert plant communities, reducing forage availability for domestic livestock and wildlife as well as seeking forage and water near human habitations, which brings them into conflict with humans. Fort Irwin, California has a relatively large population of burros (~1,000) that enter into the cantonment area, resulting in human-wildlife conflicts. We propose to estimate the size of the burro population, examine patterns of space use and employ non-lethal methods of immunocontraception or sterilization to reduce recruitment into the existing population in an attempt to reduce population size.	Feral burro populations have increased in numbers and are impacting fragile desert plant communities, reducing forage availability for domestic livestock and wildlife (Bastian et al. 1999) as well as seeking forage and water near human habitations, which brings them into conflict with humans. Fort Irwin, California has a relatively large population of burros (~1,000) that enter into the cantonment area, resulting in human-wildlife conflicts. In collaboration with the Department of Defense, we are estimating the size of the burro population, examining patterns of space use and testing the efficacy of using immunocontraception on a large, free-ranging burro population. Our resource selection modeling will provide some of the most detailed analysis to date for feral burro habitat selection and water dependency. Our results will lead to the development of mitigation strategies to reduce human-wildlife conflicts by identifying actions to reduce burro use high conflict areas. Finally, our efficacy assessment will provide guidance on immunocontraception strategies to reduce burro numbers over the long-term; including elucidation of the logistical challenges of employing currently available PZP formulations.
The ecological web contributing to a sarcoptic mange epizootic in coyotes of the Mojave Desert, Fort Irwin, California	March 2018	In order to minimize the human-wildlife conflict on Fort Irwin, we intend to explore the ecological web surrounding the sarcoptic mange epizootic in the resident coyote population and thereby develop mitigation strategies to lower disease prevalence and the overall abundance of coyotes. Our objectives will be to estimate the size of the coyote population inhabiting the base, describe the patterns of spatial use by the resident coyotes, explore the potential factors contributing to the maintenance of sarcoptic mange, and examine for other parasites and diseases through fecal, epidermal and blood assays. Through this process, we hope to identify and suggest mitigation strategies that can be adopted by the base administration that will reduce the size of the resident coyote population and enhance its health thereby reducing human wildlife-conflict and the potential for spread of disease to humans and pets.	Coyotes have readily adapted to human-modified environments. One such population, occurs at Fort Irwin, California in the Mojave Desert. In spite of the harsh environmental conditions, a sizeable population of mange-infected coyotes occupies the garrison area of the base. In order to minimize the human-wildlife conflict on Fort Irwin, we are exploring the ecological web surrounding the sarcoptic mange epizootic in cooperation with the Department of Defense. Our objectives will be to estimate the size of the coyote population inhabiting the base, describe the patterns of spatial use by the resident coyotes, explore the potential factors contributing to the maintenance of sarcoptic mange, and examine for other parasites and diseases through fecal, epidermal and blood assays.

Evaluating adaptive capacity of desert bighorn sheep to climate change: identifying genetic links to climate adaptations in native and reintroduced populations	December 2017	The predicted increased occurrence of extreme droughts, overall decline in precipitation and increase in temperature due to climate change has the potential to impact a large number of species in the southwestern United States. In spite of their adaptations, both domestic and wild ungulates are not always able to ameliorate the effects of high temperatures and limited water availability using behavioral and physiological mechanisms. The genetic basis for many physiological mechanisms that confer greater abilities on some species, subspecies or populations of wild ungulates to cope with limited water supply and high temperatures remains to be explored. Thus, understanding potential adaptations of desert bighorn sheep in the 3 southwestern desert ecosystems with varying temperature and aridity conditions has the potential to inform vulnerability of populations to potential future changes in climate and other stressors. Specifically, identifying certain genes that may be related to the ecology of the different desert environments can provide valuable insights regarding future adaptation actions (e.g., translocations) as the climate continues to change. Our objectives are to: 1) Assess whether desert bighorn sheep exhibit local adaptations to the different desert ecosystems with corresponding differences in seasonal climatic conditions; and 2) Provide recommendations on how managers can implement adaptation actions to maximize evolutionary potential.	Desert ungulates use a variety of physiological and morphological mechanisms to minimize the impacts of high temperatures and water scarcity on thermoregulation and water balance. However, the genetic basis for physiological mechanisms that confer greater abilities to cope with limited water and high temperatures remains to be explored. In collaboration with Oregon State University and the USGS Climate Change and Wildlife Science Center, we recently completed a project to identify genes related to the physiological ecology of desert bighorn sheep with a suite of single nucleotide polymorphisms using samples collected from populations across their range. The results suggest climate conditions at higher latitudes may have resulted in a distinct ecotype of desert bighorn sheep whose adaptations are still apparent in a few indigenous populations in the Great Basin. We also found two highly supported candidate genes in the genomic region linked to this outlier. Overall, these findings suggest selection from environmental factors may influence genomic variation at the ecosystem-scale in desert bighorn sheep, which extend our understanding of how this subspecies may respond to different environments.
Assessment of nutrition and predation as limiting factors for mule deer in New Mexico	December 2018	The goal of this project is to determine which factors are effectively limiting mule deer in New Mexico. Our specific objectives are to:1) estimate mule deer survival rates and determine cause-specific mortality; 2) determine mule deer pregnancy rates and fawn recruitment; 3) assess the nutritional status of mule deer by determining the quantity (i.e., biomass of available forage) and quality (nutritional content) of forage available to mule deer within the study area; 4) determine diet composition and diet quality for mule deer; 5)estimate prey composition and kill rates for mountain lions; and 6)determine how habitat selection by mule deer is influenced by habitat conditions and predation risk by mountain lions.	Mule deer have declined across New Mexico. Studies in other portions of the range indicate that predation and or nutritional limitations are contributing to declines. In collaboration with the New Mexico Department of Game and Fish, we are evaluating the relative roles of nutrition and predation on a non-migratory mule deer population. Our goals are to determine factors limiting mule deer in New Mexico. Specifically, we are estimating: 1) survival rates and cause-specific mortality; 2) pregnancy rates and fawn recruitment; 3) forage biomass and nutritional quality; 4) diet composition; 5) prey composition and kill rates for mountain lions; and 6) how habitat selection by mule deer is influenced by habitat conditions and predation risk. This project will enhance our knowledge on limiting factors driving mule deer population dynamics in semi-arid regions, including the independent and interactive effects of climate, forage dynamics and predation.

Zeigler, M.P., A.S. Todd, and C.A. Caldwell. 2013. Water temperature and baseflow discharge of Rio Grande cutthroat trout streams in Colorado and New Mexico- 2010 and 2011. U.S. Geological Survey Open-File Report 2013-1051, 18 p. +appendices. \| Abstract \| Publisher Website	April 2013	This study characterized the thermal regime in a number of Colorado and New Mexico streams that contain populations of Rio Grande cutthroat trout and had no previous record of continual temperature records. When compared to Colorado’s water temperature criteria (Cold Tier 1), a portion of these populations appeared to be at risk from elevated stream temperatures, as indicated by exceedance of both acute (17 - 22 percent) and chronic (2 to 9 percent) water quality metrics. Summer water temperature profiles recorded at sites within current Rio Grande cutthroat trout habitat indicated that although the majority of currently occupied conservation streams have temperatures that fall well below these biologically based acute and chronic thermal thresholds, several sites may be at or approaching water temperatures considered stressful to cutthroat trout. Further, water temperatures should be considered in decisions regarding the current and future thermal suitability of potential Rio Grande cutthroat trout restoration sites. Additionally, baseflow discharge sampling indicated that a majority of the sampled stream segments containing Rio Grande cutthroat trout have flows less than 1.0 cubic feet per second (cfs) in both 2010 (74 percent) and 2011 (77 percent). The relative drought sensitivity of these low baseflow streams containing Rio Grande cutthroat trout could be further evaluated to assess their probable sustainability under possible future drought conditions.
Zeigler, M.P., A.S. Todd, and C.A. Caldwell. 2012. Evidence of recent climate change within the historic range of Rio Grande cutthroat trout: Implications for management and future persistence. Transactions of the American Fisheries Society 141:1045-1059 \| Abstract	September 2012	Overwhelming evidence of anthropogenically influenced climate change has motivated natural resource managers to incorporate adaptive measures to minimize risks to sensitive and threatened species. Detecting trends in climate variables (i.e., air temperature, hydrology, precipitation) can serve as a valuable tool for managers working to protect vulnerable species by increasing our understanding of localized conditions and trends. The Rio Grande cutthroat trout Oncorhynchus clarki virginalis has suffered a severe decline in its historic distribution, with the majority of current populations persisting in isolated headwater streams. To evaluate recent climate change within the subspecies’ historic range, trends in average air temperatures, biologically-important hydrological variables (timing of snowmelt, seasonal flows), and April 1st snow water equivalent over the last 45 years (1963 - 2007) were examined. While rates of change in all three metrics were variable across sites, range-wide patterns were evident. Across the subspecies historic range average annual air temperatures increased (range-wide increase of 0.29°C per decade) and the timing of snowmelt shifted to earlier in the year (range-wide change of 10.6 days earlier). Flows increased during biologically-important periods, such as winter (January 1st - March 31st), pre-spawning (April 1st - May 14th), and spawning periods (May 15th - June 15th), and decreased in the summer (June 16th - September 15th). Evidence of decreasing April 1st snow water equivalent (range-wide decrease of 5.3% per decade) was also observed. While the impacts of these changes at the population level are equivocal, it is likely that negative effects would influence the subspecies by altering its distribution, decreasing available habitat, and altering the timing of important life history components. Continued monitoring and proactive management will be required to increase the resiliency of remaining populations to insure their long term persistence and protection from the negative effects of a climate change.

Wallin, T. and C.A. Caldwell. Comparative assessment of laboratory-derived thermal maxima of Gila Trout (Oncorhynchus gilae) with current stream temperatures. The Southwestern Naturalist 66(4):317-326. \| Abstract	February 2022	Gila Trout (<i>Oncorhynchus gilae</i>) represents an iconic species of the American Southwest. The salmonid has survived extensive logging, livestock grazing, and mining, and is currently threatened by climate change, wildfire, and extended drought. Long term conservation and recovery of the species and its unique lineages rely on stocking and translocation into historically inhabited streams. Thus, the fish’s thermal tolerance is essential in determining suitable habitat and potential vulnerability to a warming climate. We compared laboratory-derived temperature metric, critical thermal maximum (CTMax), in hatchery-reared Gila Trout from three lineages (Main Diamond, South Diamond, and Whiskey Creek) to determine if CTMax differed among the lineages. The average initial (28.9, SD = 0.81°C) and final (29.2, SD = 0.74°C) loss of righting responses did not differ across the lineages. We compared the CTMax values with stream temperatures across three drainages representative of extant Gila Trout populations from spring 2015 to fall 2018. The East Fork Gila River drainage was represented by more extreme stream temperatures. The maximum daily maximum temperature (i.e., single highest temperature) varied from 24.1 to 33.4°C, exceeding CTMax in four of the five streams. The maximum daily temperature range varied from 12.1 to 28.6°C, and the mean weekly maximum temperature varied from 19.9 to 31.1°C. Mean weekly maximum temperature in Lower Diamond Creek exceeded CTMax on eleven occasions. Stream temperatures were cooler within the Middle and the West Fork Gila River drainages and did not exceed CTMax. Intermittency loggers within the East Fork Gila River Drainage, which supports Main Diamond and South Diamond lineages of Gila Trout, recorded over 300 days of intermittency during a drought. Continued long term monitoring of stream temperature and comparison to CTMax of Gila Trout could assist with decisions of which streams in the Gila Drainage are suitable for Gila Trout recovery, stocking, and translocation.

Vaisvil, A., C.A. Caldwell, and E. Frey. Effects of water-level fluctuations and water temperature on young-of-year Largemouth Bass in a southwest Irrigation reservoir. Journal of Fish and Wildlife Management 12(2):534-543. \| Abstract	August 2022	The effects of a warming climate will alter the hydrological cycles of arid southwestern U.S. reservoirs which primarily support agricultural needs, provide flood control, and generate hydroelectric power while secondarily supporting fish communities and sport fishing opportunities. The success of littoral spawning fishes depends on the timing and variability of water levels. The onset of drought between 2017 and 2018 provided an opportunity to evaluate the timing of hatch dates and relative abundance of young-of-year Largemouth Bass<i> Micropterus salmoides </i>across two water years of varying water temperatures and water levels in a southwestern U.S. reservoir. A retrospective analysis of otoliths in young-of-year Largemouth Bass revealed similar hatch dates in 2017 (14 April–29 May) and 2018 (13 April–28 May) despite differences in water temperature and water level rate-of-change. Median water temperature during hatch dates was greater in 2017 (median 19.0°C, range 14.3–24.4°C) than 2018 (17.6°C, range 13.5–21.7°C). Water level rate-of-change during hatch dates in 2017 was positive (+3.1– +13.1 cm/d), which reflected reservoir filling. In contrast, water level rate-of-change during hatch dates in 2018 was negative (-8.5– -0.6 cm/d), which reflected reservoir receding. Relative abundance of young-of-year fish was greater in 2017 (21.7 fish/h) when the reservoir was filling compared to relative abundance in 2018 (6.8 fish/h) when the reservoir was receding. The median growth rate was greater in 2017 (1.02 mm/d) when the reservoir was filling than in 2018 (0.82 mm/d) when the reservoir was receding. Despite differences in water temperature and contrasting reservoir levels between the two water years, the Largemouth Bass population in a southwest U.S. reservoir exhibited similar hatch dates reported for the species in southeastern and northeastern U.S. reservoirs. While water demand in the 21<sup>st</sup> century may exceed availability, the opportunity exists to collaborate with water managers to benefit Largemouth Bass populations in southwestern reservoirs.

Sykes, C.L., C.A. Caldwell, and W.R. Gould. Physiological effects of potassium chloride, formalin and handling stress on bonytail Gila elegans. North American Journal of Fisheries Management. 31:291-298. \| Abstract	August 2011	A standard treatment of a 1 h bath in 750 mg/L potassium chloride (KCl) followed by a 2 h bath in formalin has been established for removal of mussel veligers when moving fish from waters positive for zebra mussels Dreissena polymorpha and quagga mussels D. bugensis. Quagga mussels have recently been found in waters inhabited by endangered bonytail Gila elegans, making bonytail a candidate species for the KCl and formalin treatment. The chemical treatment, however, also subjects the fish to a series of handling stressors which may increase the susceptibility of bonytail to pathogens and predators upon stocking. We characterized physiological changes of plasma cortisol, glucose, and osmolality over 24 h and at 14 d post-handling after exposing bonytail to KCl with one net stressor, KCl+formalin with two net stressors, and one net stressor and two net stressors without chemicals. Elevated plasma cortisol (322-440 ng/mL) and glucose (254-399 mg/dL) concentrations were observed in all treatments compared to plasma cortisol (56 ng/mL) and glucose (43 mg/dL) concentrations in control fish. While there were no detectable differences in plasma osmolality among the treatments and control fish, a detectable difference was observed between fish that were handled once versus twice. Chemical effects of stress were not observed in any of the physiological responses when the KCl treatment was compared to the one-net stressor or when KCl+formalin treatment was compared to the two-net stressor treatment. Cumulative responses, however, were observed between one net stressor and two net stressors for plasma glucose and osmolality but not for plasma cortisol. Within 24 h post-handling, plasma cortisol and glucose levels remained elevated and anecdotal observations of reduced response to stimuli was noted up to 14 d post-handling, indicating bonytail may not have completely recovered and could be more susceptible to pathogens and predators upon release.

Qualitative value of information provides a transparent and repeatable method for identifying critical uncertainty. Ecological Applications:e2824. \| Abstract \| Publisher Website	February 2023	Conservation decisions are often made in the face of uncertainty because the urgency to act can preclude delaying management while uncertainty is resolved. In this context, adaptive management is attractive, allowing simultaneous management and learning. An adaptive program design requires the identification of critical uncertainties that impede the choice of management action. Quantitative evaluation of critical uncertainty, using the expected value of information, may require more resources than are available in the early stages of conservation planning. Here, we demonstrate the use of a new qualitative index to the value ofinformation (QVoI) to prioritize which sources of uncertainty to reduceregarding the use of prescribed fire to benefit Eastern Black Rails(Laterallus jamaicensis jamaicensis), Yellow Rails (Coterminous noveboracensis), and Mottled Ducks (Anas fulvigula; hereafter, focal species) in high marshes of the U.S. Gulf of Mexico. Prescribed fire has been used as a management tool in Gulf of Mexico high marshes throughout the last 30+ years; however, effects of periodic burning on the focal species and the optimal conditions for burning marshes to improve habitat remain unknown. We followed a structured decision making framework to develop conceptual models, which we then used to identify sources of uncertainty and articulate alternative hypotheses about prescribed fire in high marshes. We used QVoI to evaluate the sources of uncertainty based on their magnitude, relevance for decision making, and reducibility. We found that hypotheses related to the optimal fire return interval and season were the highest priorities for study, whereas hypotheses related to predation rates and interactions among management techniques were lowest. These results suggest that learning about the optimal fire frequency and season to benefit the focal species might produce the greatest management benefit. In this case study, we demonstrate that QVoI can help managers decide where to apply limited resources to learn which specific actions will result in a higher likelihood of achieving the desired management objectives. Further, we summarize the strengths and limitations of QVoI and outline recommendations for its future use for prioritizing research and to reduce uncertainty about system dynamics and the effects of management actions.

Tagging effects of passive integrated transponder and visual implant elastomer on the small-bodied White Sands pupfish (Cyprinodon tularosa). Journal of Fisheries Research (online publication completed 24 September 2017); https://doi.org/10.1016/j.fisheries.2017.08.019. \| Abstract	September 2017	One of the greatest limiting factors of studies designed to obtain growth, movement, and survival in small-bodied fishes is the selection of a viable tag. The tag must be relatively small with respect to body size as to impart minimal sub-lethal effects on growth and mobility, as well as be retained throughout the life of the fish or duration of the study. Thus, body size of the model species becomes a major limiting factor; yet few studies have obtained empirical evidence of the minimum fish size and related tagging effects. The probability of surviving a tagging event was quantified in White Sands pupfish (Cyprinodon tularosa) across a range of sizes (19-60 mm) to address the hypothesis that body size predicts tagging survival. We compared tagging related mortality, individual taggers, growth, and tag retention in White Sands pupfish implanted with 8-mm passive integrated transponder (PIT), visual implant elastomer (VIE), and control (handled similarly, but no tag implantation) over a 75 d period. Initial body weight was a good predictor of the probability of survival in PIT- and VIE-tagged fish. As weight increased by 1 g, the fish were 4.73 times more likely to survive PIT tag implantation compared to the control fish with an estimated suitable tagging size at 1.1 g (TL: 39.29 ± 0.41 mm). Likewise, VIE-tagged animals were 2.27 times more likely to survive a tagging event compared to the control group for every additional 1 g with an estimated size suitable for tagging of 0.9 g (TL: 36.9 ± 0.36 mm). Growth rates of PIT- and VIE-tagged White Sands pupfish were similar to the control groups. This research validated two popular tagging methodologies in the White Sands pupfish, thus providing a valuable tool for characterizing vital rates in other small-bodied fishes.

Journal of Mammology 93:353-359 \| Abstract \| Download	July 2012	The interpretation of isotopic data gathered in the field often demands knowing the rate at which isotopes are incorporated into different tissues and species, and the discrimination factor between tissues and diet. These 2 quantities are estimated in laboratory experiments on diet shifts in which results are interpreted using simple mathematical models, which we describe here. The simplest of these models assumes that each tissue can be represented as a well-mixed, single compartment that obeys 1st-order kinetics. Fitting this model to experimental data allows estimating discrimination factors and the instantaneous rate of isotopic incorporation, l (the reciprocal of l, 1/l, equals the average residence time, t, of an atom in the tissue). In 1-compartment models the magnitude of l equals the sum of catabolic turnover and mass-specific growth rate. Examination of available data suggests that the magnitude of l scales with body mass to an exponent equal to approximately 20.25, differs between endotherms and ectotherms, and could be a useful feature in isotopic incorporation studies. We outline suggestions for the design and analysis of isotopic incorporation experiments and suggest that an increased data set of species and tissues can allow field researchers to estimate rates of incorporation from body size and growth rate data.

Ecosphere 13(12):e4321 \| Abstract \| Download \| Publisher Website	December 2022	State uncertainty of individuals within sampled populations is a ubiquitous problem in applied conservation, particularly for stage- or size-structured species subject to consumptive use. We constructed a Bayesian integrated population model (IPM) for American alligators (<i>Alligator mississippiensis</i>) in Georgetown County, South Carolina, USA using records of mark-recapture-recovery, clutch size, harvest, and nightlight survey counts collected locally, and auxiliary information on fecundity, sex ratio, and growth from other studies. We created a multistate mark-recapture-recovery model with six size classes to estimate survival probability, and we linked it to a state-space count model to derive estimates of size class-specific detection probability and abundance. Because we worked from a count dataset in which 60% of the original observations were of unknown size, we treated size class as a latent property of detections and developed a novel observation model to make use of information where size could be partly observed. Detection probability was positively associated with alligator size and water temperature, and negatively influenced by water level. Survival probability was lowest in the smallest size class (hatchlings) but was relatively similar among the other five size classes (>0.90 for each). While the two nightlight survey count sites exhibited relatively stable population trends, we detected substantially different patterns in size class-specific abundance and trends between each site, including 30–50% declines in the largest size classes at the site with greater hunting activity. Here, we illustrate the use of IPMs to produce high resolution output of latent population structure that is partially observed during the monitoring process.

Application of qualitative value of information to prioritize uncertainties about eastern black rail population recovery. Conservation Science and Practice 4:e12732. \| Abstract \| Download \| Publisher Website	May 2022	Natural resource management decisions are often made in the face of uncertainty. The question for the decision maker is whether the uncertainty is an impediment to the decision and, if so, whether it is worth reducing uncertainty before or while implementing actions. Value of information (VoI) methods are decision analytical tools to evaluate the benefit to the decision maker of resolving uncertainty. These methods, however, require quantitative predictions of the outcomes as a function of management alternatives and uncertainty, predictions which may not be available at early stages of decision prototyping. Here we describe the first participatory application of a new qualitative approach to VoI in an adaptive management workshop for Atlantic coast eastern black rail populations. The eastern black rail is a small, cryptic marsh bird that was recently listed as federally Threatened, with extremely little demographic data available. Workshop participants developed conceptual models and nine hypotheses related to the effects of habitat management alternatives on black rail demography. Here we describe the qualitative VoI framework, how it was implemented in the workshop, and the outcomes of the analysis, and offer lessons learned so that others may improve upon implementation of these methods in the future.

Freshwater Science. 41:62-76. \| Abstract	March 2022	Large-scale disturbances, such as wildfire, can markedly affect streams for years. As terrestrial areas within a watershed slowly recover, stream environments and biota can experience repeated and long-lasting challenges. In 2011, the Las Conchas wildfire burned <sup>1</sup>/<sub>3</sub> of the Valles Caldera National Preserve in northern New Mexico, USA. Seven y post-fire, streams located near the burn perimeter continue to experience varying levels of alteration (e.g., channel alteration with large diel temperature swings), whereas the terrestrial uplands have begun to recover. Extreme temperatures in stream systems may affect the aquatic community, including ectotherms such as caddisflies. These post-fire temperature ranges may increase an ectotherm’s breadth of thermal adaptation, but at metabolic costs that diminish organismal performance, such as growth, development, and fecundity. In this study we characterized in situ effects of varied thermal regimes across preserve streams on the performance of the caddisfly <i>Hydropsyche oslari</i> Banks, 1905. We measured mass and critical thermal maximum (CT<sub>max</sub>) in <i>H. oslari</i> larvae from preserve streams affected by wildfire (high temperature range) and in streams minimally affected by wildfire (low temperature range). We predicted that increased daily temperature maxima and reduced daily temperature minima (i.e., large diel temperature swings) would be associated with reduced <i>H. oslari</i> mass because of the limiting effects of suboptimal temperatures on growth. As predicted, in the weeks prior to their emergence as terrestrial adults, 5<sup>th</sup>-instar larvae within the high-temperature-range stream had reduced mass (mean 3.3 ± SE 0.55 mg) relative to larvae from the low-temperature-range stream (6.2 ± 0.69 mg). We also predicted that CT<sub>max</sub> of <i>H. oslari</i> would reflect stream thermal history. Indeed, larvae <i>H. oslari</i> from the high-temperature-range stream exhibited increased CT<sub>max</sub> (35.4 ± 0.17°C) compared with larvae from the low-temperature-range stream (34.4 ± 0.28°C). We demonstrated that the effects of wildfire on caddisflies can be long lasting, as evidenced by the reduced size at maturity and higher thermal tolerance in a caddisfly population 7 y post-fire.

The subspecies currently occupies less than 12% of its historic range, and as such, the Mescalero Apache Tribe has partnered with the U.S. Geological Survey-New Mexico Cooperative Fish and Wildlife Research Unit, New Mexico State University, U.S. Fish and Wildlife Service, and the New Mexico Department of Game and Fish to meet mutually shared goals of restoring and maintaining a Pecos strain of RGCT on tribal lands. The goal of this project was to assess the suitability of the Rio Ruidoso within the Mescalero Reservation to support a self-sustaining RGCT population by conducting a systematic and comprehensive survey to characterize water quality, physical habitat (stream size, channel gradient, channel substrate, habitat complexity, riparian vegetation cover and structure, migration barriers), macroinvertebrate assemblages, and fish communities. Seven-100 m reaches throughout three major tributaries of the Rio Ruidoso within the Tribal lands were sampled during baseflow conditions October 2010, May 2011, and June 2012. Despite the onset of severe drought of 2011, water quality, physical habitat, and fish populations revealed that the Rio Ruidoso and its three tributaries would most likely support a self-sustaining RGCT population. Pools were abundant (mean, 8.9 pools/100 m), large amount of instream woody debris was present (range, 3.8-45.6 pieces/100 m), and instream dataloggers revealed daily maximum stream temperatures rarely exceeded the water quality criteria for coldwater fishes, however, the presence of frazil and anchor ice may limit fish distribution in the winter. Aquatic macroinvertebrate samples revealed a community of benthic invertebrates reflective of high quality cool to cold water. Overall densities of brown trout, rainbow trout and brook trout were high (overall mean, 0.23 fish/m2) and were in good condition (mean relative weight range, 84.51-117.89). Should the Mescalero Apache Tribe decide to introduce RGCT, we recommend a barrier be placed below the confluence of Middle and South Fork of the Rio Ruidoso. This would protect against invasion of non-native fishes and create approximately 12 km of perennial flow. We recommend the North Fork of the Rio Ruidoso not be considered for reintroduction due to easy access for the public to reintroduce non-natives into the watershed. Lastly, we recommend implementation of a long term monitoring program of RGCT to ensure no subsequent incursion of non-native fishes.

Rio Grande cutthroat trout (<i>Oncorhynchus clarkii virginalis</i>, RGCT) occupy arid southwestern U.S.A. streams at the southern-most edge of all cutthroat trout distributions, making RGCT particularly vulnerable to the anticipated warming and drying in this region. We hypothesized that RGCT possess a portfolio of life-history traits that aid in their persistence within streams of varying temperature and stream drying conditions. We used otolith and multistate capture-mark-recapture data to determine how these environmental constraints influence life-history trait expression (length- and age-at-maturity) and demography in RGCT populations from northern New Mexico, U.S.A. We found evidence that RGCT reached maturity fastest at sites with warm stream temperatures and low densities. We did not find a strong relationship between discharge and any demographic rate, although apparent survival of mature RGCT decreased as stream temperature increased. Our study suggests plasticity in trait expression may be a life-history characteristic which can assist trailing edge populations like RGCT persist in a changing climate.

Transactions of the American Fisheries 150:651-664. doi.org/10.1002/tafs.10319 \| Abstract	September 2021	Density-dependent (DD) and density-independent (DI) effects play an important role in shaping fish growth rates, an attribute that correlates with many life-history traits in fishes. Consequently, understanding the extent to which DD and DI effects influence growth rates is valuable for fisheries assessments because it can inform managers how populations may respond as environmental conditions continue to change (e.g., threats from climate change). We used a Rio Grande Cutthroat Trout (<i>Oncorhynchus clarkii virginalis</i>, RGCT) capture-mark-recapture data set collected over two years along a temperature and density gradient in northern New Mexico streams to test the extent to which DD and DI effects interact to affect specific growth rates. We found that temperature (DI) and density (DD) interacted with RGCT life stage (i.e., immature or mature) to affect growth rates. We only detected evidence of a negative DD effect on RGCT growth for the immature fraction of a population when exposed to the warmest stream temperatures. Our results suggest that competition most strongly affected the immature portion of RGCT populations, and this effect was only detectable when temperatures were warmest and energetic stress was likely at its highest. The quadratic relationship between temperature and growth rates also demonstrated that stream temperatures were below as well as above optimal growth temperatures for RGCT. Growth rates in our RGCT populations were influenced by complex interactions of DD and DI effects and our results suggest that the negative consequences of warming trends associated with climate change on RGCT populations may be exacerbated by DD effects.

Ecosphere 11(7):e03175. \| Abstract \| Download	July 2020	We examined habitat selection in desert bighorn sheep in Cabeza Prieta National Wildlife Refuge, Arizona, USA, at multiple spatial and temporal scales to gain insight into how desert ungulates respond to variations in climatic conditions. This study highlights the importance of identifying resource selection at both spatial and temporal scales when investigating the interrelationship between species and their environment. It provides insight into the dynamics of resource selection in a desert ungulate, and how they respond to constraints imposed on them by their environment. This work provides an adaptive framework that can serve to inform strategies for managing and conserving species living in arid environments when faced with climate change.

Galindo, R., W.D. Wilson, and C.A. Caldwell. 2016. Geographic Distribution of Genetic Diversity in Populations of Rio Grande chub Gila pandora. Conservation Genetics 17:1081-1091. DOI: 10.1007/s10592-016-0845-2 \| Abstract	May 2016	In New Mexico, Rio Grande chub (Gila pandora) is a cool-water fish listed as a species of greatest conservation need and state-listed as sensitive due to habitat alterations and competition with non-native fishes. Characterizing the patterns of genetic structure and genetic diversity of populations will assist with conservation efforts by providing a baseline of genetic variation in New Mexico. Genetic relatedness within and among G. pandora populations throughout New Mexico was characterized using a suite of 11 microsatellites loci among 15 populations in three disparate river basins (Rio Grande, Pecos and Canadian). Allelic richness across 11 loci was highest in the Rio Ojo Caliente (northern range of the Rio Grande basin) while the lowest allelic richness was expressed in the Upper Rio Bonito (southern portion of the Pecos basin). Mean observed and expected heterozygosity was relatively high across all populations with low inbreeding coefficient. AMOVA revealed that moderate genetic differentiation existed among the 15 populations of G. pandora and a low genetic variation among populations within respective Rio Grande and Pecos basins. Finally, there was low genetic variation among the three basins. The STRUCTURE analysis and optimal K suggested that the 15 populations clustered into seven genetic clusters with the Upper Rio Bonito displaying the greatest genetic differentiation compared to all populations. Evaluating Q-values, populations within the upper Rio Grande drainage basin were the least structured, while the Pecos drainage populations were the most genetically differentiated. Patterns of genetic diversity among populations of G. pandora revealed that while northern Rio Grande populations contain the bulk of genetic diversity, the southern populations continue to persist despite isolation events. These patterns can be used to ensure genetic diversity is maintained by identifying source populations and improving migration to reduce the chance of local extinctions.
Fritts, MW, AK Fritts, SA Carleton, and R Bringolf. 2012. Shifts in stable isotope signatures of freshwater mussel glochidia during attachment to host fish. In Review Journal of Moluscan Studies. \| Abstract	February 2013	Freshwater mussels (Bivalvia: Unionacea) are characterized by complex lifecycles composed of multiple, distinct life-stages, including a larval stage referred to as a glochidium. The parasitic nature of larval freshwater mussels (i.e., the role that the fish hosts play in providing nutritional resources to the developing glochidia) is still uncertain. While previous work provided unique descriptions of developing glochidia while they were transforming on fish hosts, earlier studies have not explicitly documented the flow of nutrition to glochidia as they develop to the juvenile stage. Therefore, our objective was to evaluate the feasibility of using stable isotope analysis to quantitatively document the flow of nutrients between fish hosts and mussel glochidia. Glochidia were collected from nine adult plain pocketbook mussels (Lampsilis cardium) and used to inoculate largemouth bass (Micropterus salmoides) (n=27) that produced juvenile mussels for the trial. Adult mussel tissue samples, glochidia, transformed juvenile mussels, and fish gill tissues were analyzed for δ 15N and δ13C ratios. We used a linear mixing model to estimate the fraction of juvenile mussel tissue derived from the host fish’s tissue during attachment. Our analyses indicate a distinct shift in both C and N isotopic ratios from the glochidial stage to the juvenile stage during mussel development. Linear mixing model analysis indicated that 90.0% of the δ13C and 57.4% of the δ 15N in juvenile tissues was obtained from the host fish. This work provides new evidence that larval unionids are true parasites that derive nutrition from a host fish during their metamorphosis into the juvenile stage; however, future studies should investigate the relative nutritional contribution of host fishes to mussels that exhibit different glochidial morphologies and brooding periodicities. Additionally, the effects of diet and food quality on fractionation patterns in individual tissues in mussels and the relative contribution of assimilated DIC on the δC13 values of molluscan tissues should be considered.

Canadian Journal if Fisheries and Aquatic Sciences 72:1575-1583. \| Abstract	September 2015	Natal origin and dispersal potential of the federally threatened Pecos bluntnose shiner Notropis simus pecosensis were successfully characterized using otolith microchemistry and swimming performance trials. Strontium isotope ratios (87Sr:86Sr) of otoliths within the resident plains killifish Fundulus zebrinus were successfully used as a surrogate to strontium isotope ratios in water and revealed three isotopically distinct reaches throughout 297 km of the Pecos River, New Mexico, USA. Two different life history movement patterns were revealed in Pecos bluntnose shiner. Eggs and fry were either retained in upper river reaches or passively dispersed downriver and followed by upriver movement during the first year of life with some fish achieving a minimum movement of 56 km. Swimming ability of Pecos bluntnose shiner confirmed upper critical swimming speeds (Ucrit) as high as 43.8 cm.s-1 and 20.6 body lengths.s-1 in 30 d post-hatch fish. Strong swimming ability early in life supports our observations of upriver movement using otolith microchemistry and confirms movement patterns that were previously unknown for the species. Understanding patterns of dispersal of this and other small-bodied fishes using otolith microchemistry may help redirect conservation and management efforts for Great Plains fishes.
Carleton SA, CM del Rio, and TJ Robinson. Feather Isotope Analysis Reveals Differential Patterns of Habitat and Resource Use in Populations of White-Winged Doves \| Abstract \| Download	June 2015	The white-winged dove (Zenaida asiatica) serves an important ecological role as a diurnal pollinator of the iconic saguaro cactus in the Sonoran desert and an economic role as the second most harvested upland game bird in North America. White-winged doves are intimately linked to anthropogenic changes on the landscape and because of this, have experienced dramatic population fluctuations over the last 75 years. It is unclear whether this variation is due to factors affecting them on their breeding or wintering grounds. As a first step to link breeding and wintering locations for this species, we used stable isotopes of hydrogen (δ2H) and carbon (δ13C) in feather (δ2Hf and δ13Cf, respectively) to differentiate among populations of white-winged doves across their breeding range in the United States. δ2Hf and δ13Cf not only differentiated between populations of white-winged doves that breed in the United States, but further differentiated doves that breed in agricultural habitats from those that breed in native desert habitats within a portion of their range. Ecological processes associated with desert resources and anthropogenic influences, specifically irrigated crops, largely determined δ2Hf in some western white-winged dove populations whereas δ2H of precipitation (δ2Hp) determined δ2Hf of eastern populations. This study highlights the usefulness of stable isotope analysis to differentiate populations of animals across the landscape, the insight isotopes can provide into habitat and resource use by migratory animals, and the importance of characterizing breeding ground δ2Hf for bird species that breed in habitats influenced by anthropogenic factors or habitats that do not rely on seasonal precipitation before proceeding with movement studies linking breeding and wintering populations using stable isotopes.

Transactions of the American Fisheries Society 148:832-842. DOI# 10.1002/tafs.10177 \| Abstract	July 2019	The historical range of federally endangered Humpback Chub Gila cypha has diminished largely due to habitat loss and invasive species. Optimal spawning habitat exists within the Little Colorado River (LCR), however the temperatures in the LCR are also ideal for proliferation of the invasive pathogenic Asian fish tapeworm Schyzocotyle acheilognathi. The current standard for positive identification of the parasite is necropsy and visual examination of the gut via microscopy, a methodology undesirable for assessing parasitic infection in endangered fishes. A swab taken at the anogenital pore of the fish and analysed using a novel DNA primer targeting the cestode cytochrome oxidase I subunit (COI) mtDNA gene region offers a convenient non-lethal sampling methodology. To validate the non-lethal methodology, primer sensitivity (43%) and specificity (78%) were initially calculated by utilizing captive fish exposed to the parasite and comparing the results with the lethal standard (i.e., visual examination) methodology. Subsequently, we utilized this novel non-lethal methodology to address prevalence of infection and relative infection frequency within most size classes in a wild population of Humpback Chub, as well as address possible spatial patterns and mechanisms of infection. Wild Humpback Chub were screened for infections spring and fall 2015 at two locations in the Little Colorado River. Infection prevalence across study reaches for spring and fall was 19.5% (N = 159) and 6.2% (N = 292), respectively. Relative infection frequency increased in fish measuring 75 – 250 mm, and decreased in fish measuring 250 – 400+ mm. Based on these observations, juveniles and sub-adult Humpback Chub (<200 mm) may be ideal targets for anthelminthic treatment. Elevated levels of infection near the major spawning grounds of Humpback Chub promote parasitic infection, which will continue to persist without treatment or actions to control infections. Anogenital swabs, in conjunction with PCR and primer-specific identification, offers a time efficient non-lethal method to detect parasite infections in endangered fishes.

Prescription fire effects on an aquatic community of a southwest montane grasslands system. North American Journal of Fisheries Management. 33:1049-1062. \| Abstract \| Download	July 2013	Use of prescription fire has long been recognized as a reliable management tool to suppress vegetative succession processes and to reduce fuel loading to prevent catastrophic wildfires, but very little attention has been paid to the effects on aquatic systems. A late fall prescribed burn was implemented to characterize effects on an aquatic community within a montane grassland system in northcentral New Mexico, USA. The fire treatment was consistent with protocols of a managed burn except that the fire was allowed to burn through the riparian area to the treatment stream to replicate natural fire behavior. In addition to summer and fall pre-burn assessment of the treatment and a reference stream, we characterized immediate post-fire effects (within a week for macroinvertebrates and within 6 months for fish), and seasonal effects over a 2 year period. Responses within the treatment stream were compared to an unburned reference stream adjacent to the prescription burn. During the burn, the diel range in air temperature increased by 5oC while diel range in water temperature did not change. Carbon-nitrogen ratios did not differ between treatment and reference streams, indicating the contribution of ash from the surrounding grassland was negligible. Although total taxa and species richness of aquatic macroinvertebrates were not altered, qualitative indices revealed departure from pre-burn condition due to loss of sensitive taxa (mayflies and stoneflies) and an increase in tolerant taxa (midges) following the burn. Within one year of the burn, these attributes returned to pre-burn conditions. Adult Brown Trout Salmo trutta density and recruitment did not differ between pre- and post-burn collections, nor did fish condition differ. Fire is rarely truly replicated within a given study. Although our study represents one replication, the results will inform managers about the importance in timing (seasonality) of prescription burn and anticipated effects on aquatic communities.

New Mexico Department of Game and Fish – Share with Wildlife (#13-516-0000-00043). 19 pp. \| Abstract \| Download	March 2014	Conservation through restoration of imperiled fishes can result in indirect benefits to amphibian populations through removal of invasive predatory species of fish. However, very limited information is available with regards to the effects of piscicidal applications to the non-target amphibians. Of particular interest in New Mexico is the federally-listed Chiricahua leopard frog (Lithobates chiricahuensis), and the Plains leopard frog (L. blairi) listed in New Mexico as a Species of Greatest Conservation Need. These two species co-occur throughout a watershed slated for native fish restoration using a piscicide. Toxicity trials using CFT Legumine (5% rotenone) were conducted on four larval stages of L. chiricahuensis and a surrogate species for L. blairi, the northern leopard frog (L. pipiens). Larvae of L. chiricahuensis exhibited greater sensitivity than the surrogate (L. pipiens) across all Gosner stages and both species exhibited decreasing sensitivity through tadpole development. The 48 h LC50 of CFT Legumine and its active ingredient (5% rotenone) was lowest (most toxic) in L. chiricahuensis at Gosner stages 21-25 (0.42 mg/L or 21.0 µg/L rotenone). In contrast, the 48 h LC50 for L. pipiens at these earliest Gosner stages was 1.30 mg/L (65.0 µg/L rotenone). In the later Gosner stages (26-30 and 31-36) of L. chiricahuensis, toxicity effects of CFT Legumine decreased to 1.03 mg/L (51.5 µg/L) and 1.30 mg/L (65.0 µg/L rotenone), respectively. In contrast, L. pipiens was less susceptible to the piscicide at the later Gosner stages (1.26-3.06 mg/L). While both species exhibited the least sensitivity after hind limbs were complete, L. chiricahuensis continued to be more sensitive to CFT Legumine (3.40 mg/L or 170 µg/L rotenone) than L. pipiens (3.86 mg/L or 193.0 µg/L rotenone). Late Gosner stage tadpoles (37-40) of both species demonstrated a delay in metamorphosis up to 90 days (total development time) when exposed for 48 hours to sublethal concentrations of CFT Legumine. Additional research is needed to evaluate the sublethal effects of the piscicide on metamorphosis in amphibians.

Analysis of regional scale risk to whirling disease in populations of Colorado and Rio Grande cutthroat trout using a Bayesian belief network model. Journal of Risk Analysis 34:1589-1605. DOI:10.1111/risa.12189 \| Abstract	March 2014	Introduction and spread of the parasite Myxobolus cerebralis, the causative agent of whirling disease, has contributed to the collapse of wild trout populations throughout the intermountain west. Of concern is the risk the disease may have on conservation and recovery of native cutthroat trout. We employed a Bayesian belief network to assess probability of whirling disease in Colorado River and Rio Grande cutthroat trout (Oncorhynchus clarkii pleuriticus and O. c. virginalis, respectively) within their current ranges in the southwest United States. Available habitat (as defined by gradient and elevation) for intermediate oligochaete worm host, Tubifex tubifex, exerted the greatest influence on the likelihood of infection, yet prevalence of stream barriers also affected the risk outcome. Management areas that had the highest likelihood of infected Colorado River cutthroat trout were in the eastern portion of their range, although the probability of infection was highest for populations in the southern, San Juan sub-basin. Rio Grande cutthroat trout had a relatively low likelihood of infection, with populations in the southernmost Pecos management area predicted to be at greatest risk. The Bayesian risk assessment model predicted the likelihood of whirling disease infection from its principal transmission vector, fish movement, and suggested that barriers may be effective in reducing risk of exposure to native trout populations. Data gaps, especially with regards to location of spawning, highlighted the importance in developing monitoring plans that supports future risk assessments and adaptive management for subspecies of cutthroat trout.
Armstrong, B.A.W., C.A. Caldwell, M.E. Ruhl, and J.H. Bohling. Stream-wide evaluation of survival and reproduction of M_YY and wild Brook Trout populations. North American Journal of Fisheries Management. .doi:10.1002/nafm.10844 \| Abstract	September 2022	Brook Trout (<i>Salvelinus fontinalis</i>) have been widely introduced across the western U.S. where the species competes with and often replaces native salmonids. Non-native Brook Trout are difficult to eradicate; thus, complementary removal strategies are needed to manage invasive populations. One novel methodology is the M<sub>YY</sub> integrated pest management approach, which couples partial removal of a wild Brook Trout population with the stocking of M<sub>YY</sub> Brook Trout. If M<sub>YY</sub> fish survive to reproduce with wild female Brook Trout, their progeny will be 100% male, which will shift the sex ratio and theoretically extirpate the population. However, the effectiveness of the approach depends on the survival and reproduction of M<sub>YY</sub> fish relative to the surviving wild conspecifics. From 2018–2020, we annually removed 50% of the wild Brook Trout populations from three streams and replaced with fingerling M<sub>YY</sub> Brook Trout (mean TL = 94 mm, range = 61–123 mm). Annual survival for M<sub>YY</sub> and wild Brook Trout was similar in Leandro Creek (M<sub>YY</sub> 0.63 and wild 0.63) and Rito de los Piños (M<sub>YY</sub> 0.37 and wild 0.46), but lower in Placer Creek (M<sub>YY</sub> 0.28 and wild 0.75). We evaluated the reproductive success of M<sub>YY</sub> Brook Trout by comparing sexually mature M<sub>YY</sub> fish during the spawning season to hybrid (M<sub>YY</sub> x wild) F<sub>1 </sub>progeny produced in 2019 and 2020. By the second spawning season (2020), M<sub>YY</sub> fish comprised 59.8%, 50.4%, and 34.5% of the milt producing Brook Trout, which resulted in 55.1%, 33.3%, and 0% hybrid progeny in Leandro Creek, Rito de los Piños, and Placer Creek, respectively. We demonstrated M<sub>YY</sub> fish exhibit similar vital rates compared to wild conspecifics; however, differences among streams highlights unforeseen variables that influence M<sub>YY</sub> survival and reproduction. The study offers promising results of the M<sub>YY</sub> approach to eradicate unwanted Brook Trout populations.
