USGS FSP IP-127181. \| Abstract	December 2021	We investigated how lake thermal processes responded to whole-lake warming manipulation in a lake in the Alaskan Arctic through observations and numerical modeling. The warming manipulation was conducted by artificially heating the epilimnion as a proxy for climate warming. We performed numerical modeling and used an improved lake scheme based on the Community Land Model (CLM). We simulated a control run (CTL) without warming and a warming manipulation simulation (WARM). Results indicated the WARM simulation accurately captured observed lake temperature profiles where water stratification was extended in time, and water stability was strengthened. Two additional sensitivity tests with different warming onset dates and of the same warming duration showed that earlier onsets of warming are predicted to make the lake water column more stable and less easily mixed relative to a later onset of warming. The results of this study provide a more complete understanding of lake thermal processes in arctic freshwater lake systems and how they will respond to predicted future warming.

USGS FSP IP-065178. \| Abstract	January 2015	Species interactions within novel fish assemblages in highly-managed reservoir systems can be difficult to predict and understand. In a high elevation Utah reservoir, USA, the unintentional introduction of Utah Chub Gila atraria and subsequent population expansion prompted managers to shift from stocking exclusively Rainbow Trout Oncorhynchus mykiss to include Tiger Trout Salmo trutta (female) x Salvelinus fontinalis (male) and Cutthroat Trout O. clarkii utah, a novel suite of top predators and potential competitors. We examined the interspecific interactions among Scofield Reservoir, Utah piscivores using a multifaceted approach including gut analyses, stable isotopes, and gape limitation studies to characterize the potential for competition and predation to occur amongst top predators. Our results suggest large Cutthroat Trout and Tiger Trout occupy a top piscivore trophic niche and are more littoral, but because food resources are not limited, competition is unlikely. In contrast, Rainbow Trout occupy an omnivore niche space and are more pelagic. Apparent survival of Rainbow Trout has declined significantly in recent years, potentially due to shared food resources or preferred feeding space with Utah Chub. In contrast, Cutthroat Trout and Tiger Trout are capable of consuming prey up to 50% of their own size, much larger than predicted based on their theoretical gape limit alone. Collectively, this research aids in understanding biotic interactions within a top-heavy and novel fish community and assists towards developing and implementing suitable management strategies to control nuisance species in valuable sport fisheries.

Canadian Journal of Fisheries and Aquatic Sciences Volume 78. doi.org/10.1139/cjfas-2020-0353. USGS FSP IP-121942. \| Abstract	May 2021	Increasing water demand, water development, and on-going climate change have driven extensive changes to the hydrology, geomorphology and biology of arid-land rivers globally, driving an increasing need to understand how annual hydrologic conditions affect the distribution and abundance of imperiled desert fish populations. We analyzed the relationship between annual hydrologic conditions and the endangered Rio Grande silvery minnow in the Middle Rio Grande, New Mexico, USA, using hurdle models to predict both presence and density as a function of integrated annual hydrologic metrics. Both presence and density were positively related to spring high flow magnitude and duration and negatively related to summer drying, as indicated by an integrated flow metric. Simulations suggest hydrologic conditions near the wettest observed in the data set would be required to meet recovery goals in a single year in all reaches. We demonstrate how the models developed herein can be used to examine alternative water management strategies, including strategies that may currently be socially and logistically infeasible to implement, to identify strategies minimizing trade-offs between conservation and other management goals.

DOI: 10.1093/beheco/arab147 \| Abstract	June 2022	Individual variation in behavior, particularly consistent among-individual differences (i.e., personality), has important ecological and evolutionary implications for population and community dynamics, trait divergence, and patterns of speciation. Nevertheless, individual variation in spatial behaviors, such as home range behavior, movement characteristics, or habitat use has yet to be incorporated into the concepts or methodologies of ecology and evolutionary biology. To evaluate evidence for the existence of consistent among-individual differences in spatial behavior – which we refer to as “spatial personality” – we performed a meta-analysis of 200 repeatability estimates of home range size, movement metrics, and habitat use. We found that the existence of spatial personality is a general phenomenon, with consistently high repeatability (r) across classes of spatial behavior (r = 0.67 - 0.82), taxa (r = 0.31 - 0.79), and time between repeated measurements (r = 0.54 - 0.74). These results suggest: (1) repeatable spatial behavior may either be a cause or consequence of the environment experienced and lead to spatial personalities that may limit the ability of individuals to behaviorally adapt to changing landscapes; (2) interactions between spatial phenotypes and environmental conditions could result in differential reproduction, survival, and dispersal, suggesting that among-individual variation may facilitate population-level adaptation; (3) spatial patterns of species’ distributions and spatial population dynamics may be better understood by shifting from a mean field analytical approach towards methods that account for spatial personalities and their associated fitness and ecological dynamics.

Canadian Journal of Fisheries and Aquatic Sciences 77:1564-1573. \| Abstract	June 2020	The ability of PIT tag data to improve demographic parameter estimates has led to the rapid advancement of PIT tag systems. However, ghost tags create uncertainty about detected tag status (i.e. live fish or ghost tag) when using mobile interrogation systems. We developed a method to differentiate between live fish and ghost tags using a random forest classification model with a novel data input structure based on known fate PIT tag detections in the San Juan River, NM, CO, and UT, USA. We used our model to classify detected tags with an overall error rate of 6.8% (1.6% ghost tags error rate and 21.8% live fish error rate). The important variables for classification were related to distance moved and response to flood flows; however, habitat variables did not appear to influence model accuracy. Our results and approach allow the use of mobile detection data with confidence and allow for greater accuracy in movement, distribution, and habitat use studies, potentially helping identify influential management actions improving our ability to conserve and recover endangered fish.

Shrinking body size and climate warming: Many freshwater salmonids do not follow the rule. Global Change Biology 2023;29:2478–2492. USGS FSP under Al-Chockhachy, IP-146706. \| Abstract	January 2023	Declining body size is believed to be a universal response to climate warming andhas been documented in numerous studies of marine and anadromous fishes. TheSalmonidae are a family of coldwater fishes considered to be among the most sensitivespecies to climate warming; however, whether the shrinking body size responseholds true for freshwater salmonids has yet to be examined at a broad spatial scale.We compiled observations of individual fish lengths from long-termsurveys acrossthe Northern Hemisphere for 12 species of freshwater salmonids and used linearmixed models to test for spatial and temporal trends in body size (fish length) spanningrecent decades. Contrary to expectations, we found a significant increase in lengthoverall but with high variability in trends among populations and species. More thantwo-thirdsof the populations we examined increased in length over time. Secondaryregressions revealed larger-bodiedpopulations are experiencing greater increases inlength than smaller-bodiedpopulations. Mean water temperature was weakly predictiveof changes in body length but overall minimal influences of environmentalvariables suggest that it is difficult to predict an organism's response to changingtemperatures by solely looking at climatic factors. Our results suggest that decliningbody size is not universal, and the response of fishes to climate change may be largelyinfluenced by local factors. It is important to know that we cannot assume the effectsof climate change are predictable and negative at a large spatial scale.

Ecology of Freshwater Fish. doi: 10.1111/eff.12143. USGS FSP: IP-034361. \| Abstract	April 2014	Exotic species present a great threat to native fish conservation; however, eradicating exotics is expensive and often impractical. Mechanical removal can be ineffective for eradication, but nonetheless may increase management effectiveness by identifying portions of a watershed that are strong sources of exotics. We used mechanical removal to understand processes driving exotic brown trout (Salmo trutta) populations in the Logan River, Utah. Our goals were to: (i) evaluate the demographic response of brown trout to mechanical removal, (ii) identify sources of brown trout recruitment at a watershed scale and (iii) evaluate whether mechanical removal can reduce brown trout densities. We removed brown trout from 2 km of the Logan River (4174 fish), and 5.6 km of Right Hand Fork (RHF, 15,245 fish), a low-elevation tributary, using single-pass electrofishing. We compared fish abundance and size distributions prior to, and after 2 years of mechanical removal. In the Logan River, immigration to the removal reach and high natural variability in fish abundances limited the response to mechanical removal. In contrast, mechanical removal in RHF resulted in a strong recruitment pulse, shifting the size distribution towards smaller fish. These results suggest that, before removal, density-dependent mortality or emigration of juvenile fish stabilised adult populations and may have provided a source of juveniles to the main stem. Overall, in sites demonstrating strong density-dependent population regulation, or near sources of exotics, short-term mechanical removal has limited effects on brown trout populations but may help identify factors governing populations and inform large-scale management of exotic species.

USGS FSP IP-155481, BOA Date: November 7, 2023. \| Abstract	February 2024	Stream restoration programs employ beaver-related restoration techniques, including beaver translocations and installation of beaver dam analogs (BDAs), to create complex in-stream habitat. Our goal was to investigate whether BDA installations improved the probability of translocated beavers surviving and colonizing a section of degraded desert river. We translocated beavers fitted with VHF and/or PIT tags to the Price River in east-central Utah, for two years before and after BDAs were installed. We monitored survival and site fidelity of VHF-tagged beavers across all four years to estimate apparent survival, using model selection to evaluate models with BDA, flow, and other factors hypothesized to be related to apparent survival. We found similar apparent survival (<i>φ</i>) eight weeks post-release of pre-BDA beavers (<i>φ </i>= 0.50 ± 0.08 SE) and post-BDA beavers (<i>φ</i> = 0.41 ± 0.06 SE). Fifteen predation-caused mortalities occurred, and 43 beavers emigrated outside of the study site. Top models indicated apparent survival was negatively related to mean flow. Of the 70 BDAs that were constructed, we observed signs of beaver activity on two structures and the number of intact natural dams decreased due to monsoon floods. Our results suggest BDAs may not improve survival or site fidelity of translocated beavers in desert river systems. However, the negative relationship between flow and apparent survival suggests survival or fidelity may be improved if beaver translocations are timed to avoid high-flow events. Additional research is needed to understand how habitat, individual behavior, and resident conspecifics influence beaver translocation success.

Biological Conservation. 301: https://doi.org/10.1016/j.biocon.2024.110865 \| Abstract	November 2024	Woody plant encroachment and row-crop agricultural land conversion are existential threats to species that rely on grassland ecosystems. The American burying beetle (<i>Nicrophorus americanus</i>) is a threatened species whose largest remnant populations are predominantly located in grassland ecoregions comprised of privately-owned ranching lands. Here, we seek to determine functional scaling patterns and population trends of the American burying beetle in the face of conservation threats and grassland restoration. We used 13 years (2007 – 2019) of American burying beetle abundance data collected from permanent sampling locations across the Loess Canyons ecoregion (Nebraska, USA), where a network of ranchers have been restoring large-scale grasslands. To estimate beetle abundance relative to land cover variables, we developed a Bayesian N-mixture model, incorporating the Bayesian latent indicator scale selection (BLISS) method to probabilistically determine at which scales land cover variables best explained beetle abundance. American burying beetle abundance significantly increased across the ecoregion, despite high interannual variation in abundance. Increases in beetle abundance were associated with large-scale (1,149 ha extent) grassland cover. Decreases in abundance were associated with large-scale crop conversion (590 ha extent) and large-scale increases in woody cover (1,149 ha extent). This study provides the first evidence of ecoregion-scale population increases of the American burying beetle. These increases are tied to landscape variables that are managed in a large-scale, coordinated private lands grassland restoration effort. Our results suggest that successful grassland restoration will depend on coordinating across property boundaries to implement conservation at scales necessary to conserve species that require large-scale, unfragmented grasslands.

Submitted to River Research and Applications. DOI: 10.1002/rra.4213. USGS FSP IP: 147695. \| Abstract \| Download	September 2023	Widespread hydrologic alterations have simplified in-stream habitats in rivers globally, driving population declines and local extirpations of many native fishes. Here, we examine how extreme geomorphic change in a historically degraded desert river has impacted habitat diversity and persistence. Due to the introduction of a sediment plug from a tributary wash in 2010, a large reach of the degraded and simplified San Rafael River, Utah, began to actively change from a single-thread channel to a complex, multi-threaded riverscape. We combined field measurements and drone-collected imagery to document habitat changes due to this new habitat feature and monitored habitat use by native and endemic fishes. Our results demonstrate the habitat feature is more diverse than any other stream reach along the lower SRR, with reaches located at the edge of the expanding wash feature containing 17% more complex habitat (e.g., pools, riffles, backwaters) on average than reference reaches, and containing 641% more diverse habitat overall than 5 years prior to the start of our study. The wash feature is also retaining water for periods beyond what is expected during seasonal drying, with the total extent of inundation within the riverscape increasing by over 2,800%. Since the formation of the 2010 sediment plug, riparian habitat has increased by 230% since 2009, and channel networks have expanded from a single thread channel to more than 50 distinct channels throughout the sediment plug’s zone of influence. These results will inform management and conservation of habitat for imperiled desert fishes and encourage the use of process-based restoration tools such as “low-tech” habitat restoration in order to mitigate the impacts of simplification and increase habitat persistence in the face of increasing aridity in the desert Southwest.

USGS FSP IP- 138466. \| Abstract	May 2022	Desert riverscape restoration practitioners must contend with compounding effects of increasing human water demand, persistent drought, nonnative species establishment, and climate change, which further stress desert riverine ecosystems such as rivers in the Colorado River basin, USA. Herein, we provide our perspective on the importance of natural flows, large floods in particular, for successful conservation and restoration of riverscapes. We present ideas developed from our experience with restoration projects across multiple desert tributary rivers with varying levels of habitat degradation and water abstraction. We propose broad-scale measures such as protection of in-stream flows, tailoring restoration efforts to available annual water availability, and working with nature using low-tech process-based techniques to more completely address the mechanisms of habitat degradation, such as flow reduction and vegetation-induced channel narrowing. Traditionally, restoration efforts in the Colorado River basin take place at relatively fine-scales, at convenient locations and, largely focus on reducing nonnative plant and fish species. We suggest that we need to think more broadly and creatively, and that conservation or restoration of natural flow regimes is crucial to long-term success of almost all management efforts for both in-stream and riparian communities.

However, infrastructure, societal needs, and watershed runoff constrain which and when flow regime attributes can be mimicked. We compared fish assemblage responses, including native and nonnative species, over two decades of managed environmental flows to those in a river retaining a relatively natural flow regime. Both of these arid-land rivers are within the Colorado River basin and have experienced declines in watershed runoff over the past twenty years. We predicted fish-flow relationships would be conserved across time and between managed and unmanaged rivers. Declines in flow in both rivers coincided with declines in some native fishes, and more native and nonnative fish species exhibited declines in the managed river than in the unmanaged river. Our ability to detect previously documented native fish-flow relationships diminished in the managed river system because established environmental flow targets were not met due to water management, but we detected these fish-flow relationships in the unmanaged river. Our results suggest declining watershed runoff and increased consumptive water use could reduce the effectiveness of environmental flows that have lower priority in most years.

River Research and Applications. DOI: 10.1002/rra.4334. USGS FSP IP- 160668 \| Abstract	July 2024	Flow regulation, water abstraction, and riparian vegetation encroachment are causing habitat simplification with severe consequences for native fishes. We experimentally added wood to simplified habitat in a large, arid-land river to assess the effectiveness of enhancing simplified habitat. We added wood at 19 paired treatment and reference (no wood added) subreaches (50 - 100m) within the main channel of the San Juan River (SJR). Using a before-after-control-impact design, we sampled fishes and macroinvertebrates, and quantified habitat complexity. After wood addition, native fish densities were 2.2x higher in treatments compared to references, whereas nonnative fish densities exhibited no response. Macroinvertebrate densities were 6.8x higher, and habitat variation increased in treatments. The number of geomorphic features in treatments increased from 1 to a maximum of 11 following wood addition, whereas the number of features in references remained unchanged. The results suggest wood addition as a viable management strategy, enhancing native fish habitat by increasing food sources and facilitating habitat complexity at fine scales. As flow management faces challenges due to water overallocation and increased aridity, managers may consider integrating non-flow alternatives like abundant, invasive wood addition to improve habitat conditions.

DOI 10.1007/s10530-016-1322-z. USGS IP-069503 \| Abstract	November 2016	Trout species often segregate along elevational gradients, yet the mechanisms driving this pattern are not fully understood. On the Logan River, Utah, USA, exotic brown trout (Salmo trutta) dominate at low elevations but are near-absent from high elevations with native Bonneville cutthroat trout (Onchorhynchus clarkii utah). We used a Bayesian, spatial modeling approach to evaluate abiotic conditions (describing mechanisms related to temperature and physical habitat) potentially influencing the distribution of brown trout in this system. We also considered the influence of propagule pressure, including the intensity of past stocking pressure and distance from a concentrated stocking area. The distribution of brown trout was best explained by models describing: 1) average summer temperature interacting with unit stream power, our measure of gravel availability for spawning (R2=0.54), and 2) the prevalence of anchor ice between each reach and a high-intensity stocking area, also interacting with our measure of gravel availability (R2=0.52). Based on these findings, effects of cold summer temperatures on age-0 survival and/or the lack of movement upstream due to anchor ice are likely mechanisms contributing to low abundance of brown trout at high elevations. The potential role of anchor ice in affecting longitudinal distributions of brown trout has not been well-explored in other research. These findings have implications for future brown trout expansion upstream given some evidence suggesting anchor ice prevalence on the Logan River has decreased significantly over the last several decades, likely in response to climatic changes.

USGS FSP: IPDS: IP-042175. \| Abstract	April 2014	We explored potential negative effects of exotic brown trout (Salmo trutta) on native sculpin (Cottus sp.) on the Logan River, Utah, USA by (i) examining factors most strongly correlated with sculpin abundance (e.g., abiotic conditions or piscivory?), (ii) contrasting the extent of brown trout predation on sculpin with that by native cutthroat trout (Oncorhynchus clarkii utah) and (iii) estimating the number of sculpin consumed by brown trout along an elevational gradient using bioenergetics. Abundance of sculpin across reaches showed a strong (r ≥ 0.40) and significant (P < 0.05) correlation with physical variables describing width (positive) and gradient (negative), but not with abundance of piscivorous brown trout or cutthroat trout. In mainstem reaches containing sculpin, we found fish in 0% of age-1, 10% of age-2 and 33% of age-3 and older brown trout diets. Approximately 81% of fish consumed by brown trout were sculpin. Despite a similar length–gape relationship for native cutthroat trout, we found only two fish (one sculpin and one unknown) in the diets of native cutthroat trout similar in size to age-3 brown trout. Based on bioenergetics, we estimate that an average large (> 260 mm) brown trout consumes as many as 34 sculpin per year. Nevertheless, results suggest that sculpin abundance in this system is controlled by abiotic factors and not brown trout predation. Additional research is needed to better understand how piscivory influences brown trout invasion success, including in-stream experiments exploring trophic dynamics and interactions between brown trout and native prey under different environmental conditions.

Submitted to River Research and Applications, 28 December, 2017. USGS FSP: \| Abstract	January 2018	In the Intermountain West, USA, eggs and fry of fall-spawning brown trout are susceptible to scour-related mortality because they are still in the gravel during spring snowmelt run-off events. The goal of our research was to understand patterns of gravel scour on the Logan River, Utah in relation to brown trout spawning preferences and whether mobility of spawning gravels could explain the absence of brown trout from higher elevations. We collected data to characterize local and reach-scale potential for spawning gravel scour (i.e., “entrainment potential”) at representative reaches along a longitudinal gradient during 2009 and 2010 spring flood events. We also used scour chains to measure scour depth at spawning locations. The flood magnitude in both years approximated the 2-year flood magnitude, but the flood in 2009 was much longer in duration. Scour at 27% of scour chain locations exceeded our estimated median depth of developing fry in 2009, while scour at 0% of locations exceeded this depth in 2010. Fewer low-gradient reaches were present in the upstream, non-canyon sections. However, across all reaches, we found that brown trout preferentially chose locations in channel margins for spawning, which tended to have low entrainment potential. These local estimates of entrainment potential predicted scour depth better than reach-scale estimates or broad-scale patterns of geomorphology. Some of the greatest scour depths were measured in the backwaters of a dam, a location with low entrainment potential but potentially greater sediment supply. Our findings suggest that spawning gravel scour is not limiting brown trout abundance at high elevations in this system given shallow scour depths overall and selection of low-scour areas for spawning.

North American Journal of Fisheries Management. DOI: 10.1002/nafm.10879. USGS FSP IP- 136834. \| Abstract	January 2023	Increased drought frequency and severity due to climate change can compound development pressures on water storage reservoirs throughout the western U.S. with uncertain effects on economically and ecologically valuable fisheries. Island Park Reservoir is a mid-sized hypolimnetic-release water storage reservoir on the Henrys Fork River in Idaho that supports a popular sport fishery for kokanee <i>Oncorhynchus nerka</i>. A region-wide drought in 2021 provided an opportunity to use Island Park Reservoir as a case study to examine how drought-induced drawdown affects kokanee habitat. We hypothesized that drawdown reduces the volume of water in the reservoir featuring “optimal” water quality for kokanee. We monitored water quality at five locations in Island Park Reservoir from spring turnover to fall turnover, from which we calculated the approximate volume of “optimal” (<17 C, >5 mg/L O<sub>2</sub>), “survivable” (<20C, >3 mg/L O<sub>2</sub>), and “lethal” (>20 C, <3 mg/L O<sub>2</sub>) conditions for kokanee. We found severe drawdown had a disproportionately negative impact on kokanee habitat availability. Although there was spatial and temporal heterogeneity in the availability of optimal and survivable conditions, drawdown for downstream water supply was the central mechanistic driver of declines in optimal and survivable conditions. Our findings explain interannual patterns in long-term kokanee spawning run return numbers, which were higher with higher reservoir carryover. Water conservation and precision management in the Henrys Fork watershed saved ~39 million m<sup>3 </sup>(32,000 acre-feet) in Island Park Reservoir in 2021, resulting in a ~150% increase in future spawning kokanee numbers from ~250 to ~650 in the 4,500 m study reach. Our study highlights the effects of drawdown on fisheries in water storage reservoirs and illustrates the degree to which hydrologic management, including projects to reduce water consumption, can benefit reservoir fish populations.

USGS FSP IP 157531 BAO Date: June, 18, 2023. \| Abstract	August 2024	Physical and biotic processes affecting trout habitat extent and quality often vary differentially across scales with the net effect oftentimes uncertain. For example, submerged macrophytes have conflicting effects on overall trout habitat by reducing preferred habitat extent within a river channel while simultaneously increasing a river channel’s productivity and growth potential. In the Henrys Fork River, Idaho, USA, we hypothesized higher submerged macrophyte coverage at the reach scale would exert a negative influence on the proportion of preferred trout habitats—defined as “habitat extent”—but would improve biotic habitat quality as measured by reach-scale models of Net Rate of Energy Intake (NREI). We therefore hypothesized a neutral or positive relationship between reach-scale submerged macrophyte coverage and a measure of net trout habitat suitability. Through random habitat sampling, aerial imagery, and snorkel surveys, we found macrophyte coverage resulted in a complementary riverscape of five habitat types. Macrophyte clumps created geomorphic forces that gave rise to intermacrophyte spaces and contributed to the formation of the remaining habitat types: gravel bars, emergent margins, and the thalweg. When testing the relationship between submerged macrophyte coverage and trout habitat, we found our hypothesized models of how habitat metrics interact with submerged macrophyte coverage appeared to fit the data well. Habitat extent declined quadratically with increasing submerged macrophyte coverage, whereas habitat quality increased exponentially. As a result, weighted trout habitat suitability changed little. As our study only featured a moderate range of macrophyte coverage (from 32 to 94% available surface area), future testing across a wider range of coverages may provide a more thorough test of our hypotheses. Nonetheless, our results highlight the importance of submerged macrophyte coverage to trout habitat via geomorphic effects. Our results also highlight the importance of trout habitat plasticity as well as habitat quality in determining overall habitat suitability.

DOI: 10.1111. \| Abstract	January 2015	A critical decision in species conservation is whether to target individual species or a complex of ecologically similar species. Management of multispecies complexes is likely to be most effective when species share similar distributions, threats, and response to threats. We used niche overlap analysis to assess ecological similarity of 3 sensitive desert fish species currently managed as an ecological complex. We measured the amount of shared distribution of multiple habitat and life history parameters between each pair of species. Habitat use and multiple life history parameters, includingmaximum body length, spawning temperature, and longevity, differed significantly among the 3 species. The differences in habitat use and life history parameters among the species suggest they are likely to respond differently to similar threats and that most management actions will not benefit all 3 species equally. Habitat restoration, frequency of stream dewatering, non-native species control, and management efforts in tributaries versus main stem rivers are all likely to impact each of the species differently.

USGS IP-053441. \| Abstract	April 2015	Persistence of many desert river species is threatened by a suite of impacts linked to water infrastructure projects that provide human water security where water is scarce. Many desert rivers have undergone regime shifts from spatially and temporally dynamic ecosystems to more stable systems dominated by homogenous physical habitat. Restoration of desert river systems could aid in biodiversity conservation, but poses formidable challenges due to multiple threats and the infeasibility of recovery to pre-development conditions. The challenges faced in restoring desert rivers can be addressed by incorporating scientific recommendations into restoration planning efforts at multiple stages, as demonstrated here through an example restoration project. In particular, use of a watershed- scale planning process can identify data gaps and irreversible constraints, which aid in developing achievable restoration goals and objectives. Site-prioritization focuses limited the resources for restoration on areas with the greatest potential to improve populations of target organisms. Investment in research to understand causes of degradation, coupled with adoption of a guiding vision is critical for identifying feasible restoration actions that can enhance river processes. Setting monitoring as a project goal, developing hypotheses for expected outcomes, and implementing restoration as an experimental design will facilitate adaptive management and learning from project implementation. Involvement of scientists and managers during all planning stages is critical for developing process- based restoration actions and an implementation plan to maximize learning. The planning process developed here provides a roadmap for use of scientific recommendations in future efforts to recover dynamic processes in imperiled riverine ecosystems.

USGS FSP: IP-XX. \| Abstract	January 2018	Management actions aimed at eradicating exotic fish species from riverine ecosystems can be better informed by forecasting abilities of mechanistic models. We illustrate this point with an example of the Logan River, Utah, originally populated with endemic cutthroat trout (Oncorhynchus clarkii utah), which compete with exotic brown trout (Salmo trutta). The coexistence equilibrium was disrupted by a large scale, experimental removal of the exotic species in 2009-2011 (on average, 8.2% of the stock each year), followed by a increase in the density of the native species. We built a spatially-explicit, reaction-diffusion model encompassing four key processes: habitat heterogeneity, competition, dispersal, and a management action. The model was calibrated with detailed long-term monitoring data collected along the 35-km long river main channel since 2001. Our model, although simple, did a remarkable job reproducing the system steady state prior to management. Insights gained from the model predictions are that the exotic species is more competitive; however, the native species still occupies more favorable habitat and has superior growth. Dynamic runs of the model also recreated the increase of the native species following the management action, with two possible distinct outcomes: recovery or suppression/eradication of the exotic species. The processing of available knowledge using Bayesian methods allowed us to conclude that the chance for suppression/eradication of the invader was 15.4%. We show that accessible mathematical and numerical tools can provide highly informative insights for managers (e.g., outcome of their conservation actions), identify knowledge gaps as well as provide testable theory for researchers.

USGS FSP IP-109849. \| Abstract	October 2020	With low species diversity and primary production across arctic lakes, trophic structure (e.g., top predator species, predator size) is surprisingly variable. We investigated trophic structure in lakes of arctic Alaska containing arctic char <i>Salvelinus alpinus</i> using predator diets and stable isotopes in two geographically-close but hydrologically-distinct lake clusters to investigate how these fishes may interact and compete for limited food resources. Aside from different lake connectivity patterns (‘leaky’ versus ‘closed’), differing fish communities (up to five versus only two species) between lake clusters allowed us to test food web hypotheses including: 1) arctic char are more piscivorous, and thereby grow larger and obtain higher trophic positions, in the presence of other fish species; and, 2) across arctic char size classes, resource polymorphism is more prominent, and thereby trophic niches are narrower and overlap less, in the absence of other predators. Regardless of lake cluster, we observed little direct evidence of arctic char consume other fishes, but char were larger (mean TL = 468 vs. 264 mm) and trophic position was higher (mean TP = 4.0 vs 3.8 for large char) in lakes with other fishes. Further, char demonstrated less intraspecific overlap when other predators were present whereas niche overlap was up to 100% in closed, char only lakes. As hydrologic characteristics (e.g., lake connectivity, water temperatures) will change across the Arctic owing to climate change, our results provide insight regarding potential concomitant changes to fish interactions and increase our understanding of lake trophic structure to guide management and conservation goals.

Ecological Engineering 58:371-377. \| Abstract	July 2013	Riparian vegetation may recover quickly from disturbance when the disturbance vector is removed or reduced. Grazing is a disturbance that removes plant biomass through herbivory, while overgrazing is a more severe disturbance that can deplete plant propagule pools and inhibit plant community recovery. We tested the hypothesis that riparian vegetation communities can shift quickly from ruderal grasslands to hydrophytic shrubs and graminoids when grazing is largely eliminated from riparian areas. We used a before-after-control study design to collect vegetation community data at six restored reaches and two grazed control reaches prior to and immediately following the construction of a cattle exclosure. We identified trends in Carex and Salix species abundance and quantified shifts in riparian vegetation community composition across time at each reach using PERMANOVA, multi-level pattern analysis and non-metric multidimensional scaling. Vegetation composition changed rapidly in the four years following removal of grazing disturbance. Indicator species for all impact reaches shifted away from grazing tolerant graminoids and forbs, and toward hydrophytic graminoid and shrub species. Over the same timespan control reach indicator species remained grazing-tolerant graminoids and forbs. There was little change in Salix abundance over time at control or impact reaches but Carex abundance increased at restored reaches. We conclude that herbaceous plant communities may recover rapidly following the removal of grazing disturbance, but that woody species may lag in recovery without active vegetation manipulation. We postulate that low woody-species recruitment may affect the potential of the riparian zone to quickly shade stream channels and facilitate undercut bank formation, common riparian restoration objectives. To prevent halted riparian succession, designers should proactively identify potential limitations to woody vegetation colonization. We close discussing active approaches to overcome stalled riparian ecosystem development and suggest metrics for assessing woody species recovery.

USGS FSP: IP-066465. \| Abstract	January 2018	Pyramid Lake, Nevada remains one of the last strongholds for lacustrine Lahontan cutthroat trout (Oncorhynchus clarkii henshawi; LCT), following historical declines throughout their native range. In Pyramid Lake, LCT have persisted despite anthropogenic alterations, and the population now depends entirely on stocking programs and efficient management. The purpose of this study was to identify important food-web interactions and potential limitations to the LCT population. The objectives were to 1) compare seasonal depth distributions, seasonal diet overlap, and trophic niche overlap between LCT and non-native Sacramento perch (Archoplites interruptus); and 2) to evaluate the seasonal depth distribution patterns of LCT and native tui chub (Gila bicolor), seasonal changes in LCT diet, and current LCT trophic position (TP). LCT remain apex predators, with both trophic position (large LCT TP = 4.30 ± 0.04 [mean±1.96∙SE]) and diet composition indicating high rates of piscivory (average annual rate of piscivory = 77.1% for large LCT; > 400 mm TL) throughout the year. Small LCT (200 – 400 mm TL) exhibited weak dietary overlap (Schoener’s Index = 0.55) and large LCT exhibited strong overlap (0.72) with Sacramento perch. Small and large LCT, and Sacramento perch, preyed most heavily on tui chub. Isotope data indicates strong overlap between large LCT and Sacramento perch niche space (large LCT 88.6%); however, catch rates indicate that Sacramento perch are only present in small numbers throughout the lake. LCT demonstrate high rates of piscivory, are not negatively influenced by the presence of Sacramento perch and do not appear to be exceeding carrying-capacity.

Remarkable response of native fishes to invasive trout suppression varies with trout density, temperature, and annual hydrology. Canadian Journal of Fisheries and Aquatic Sciences 77(9):1446-1462. USGS FSP IP-117490. \| Abstract \| Download	June 2020	Invasive species and habitat loss are among the greatest threats to riverine biodiversity. Novel habitats created through extensive river regulation, characterized by altered flow, sediment, and thermal regimes often favor invasive fishes over native species. Consequently, invasive fish suppression is a key component of endangered fish recovery programs in the Colorado River, but outcomes are often confounded by environmental variation. We studied the response of desert fishes to a brown trout (<i>Salmo trutta</i>) and rainbow trout (<i>Oncorhychus mykiss</i>) suppression program in a Colorado River tributary with natural flow patterns, and longitudinal variation in thermal characteristics similar to a tailwater. We investigated trends in fishes related to salmonid suppression, and drivers of native fish distribution and abundance across thermal and hydrological gradients using generalized-linear mixed-effects models. We observed declines in salmonid abundance of 89.3%, and concurrent increases in native fishes of ~480%; greatest increases occurred in warmer reaches and in years with spring flooding. Our results suggest recovery of imperiled native fishes can be achieved through suppression of salmonids, but outcomes may vary with temperature and flow characteristics. Thus, invasive species suppression, and efforts to mimic natural flow and thermal regimes may allow for the recovery of native fishes.

USGS FSP IP-138467. \| Abstract \| Publisher Website	September 2022	Invasive species can dramatically alter ecosystems, but eradication is difficult, and suppression is expensive once they are established. Uncertainties in the potential for expansion and impacts by an invader can lead to delayed and inadequate suppression, allowing for establishment. Metapopulation viability models can aid in planning suppression actions to improve responses to invaders and lessen invasive species’ impacts, which may be particularly important under climate change. We used a spatially-explicit metapopulation viability model to explore suppression strategies for an ecologically-damaging invasive fish, brown trout (<i>Salmo trutta</i>), established in the Colorado River and a tributary within Grand Canyon National Park. Our goals were to: 1) estimate the effectiveness of strategies targeting different life stages and subpopulations within a metapopulation, 2) quantify the effectiveness of a rapid response to a new invasion relative to waiting until establishment; and 3) estimate whether future hydrology and temperature regimes related to climate change and reservoir management affect metapopulation viability and alter the optimal management response. We included scenarios targeting different life-stages with spatially-varying intensities of electrofishing, redd destruction, incentivized angler harvest, piscicides, and a weir.<b> </b>Quasi-extinction (QE) was obtainable only with metapopulation-scale suppression targeting multiple life-stages; subpopulations were most sensitive to age-0 and large adult mortality. The duration of suppression needed to reach QE for a large established subpopulation was triple compared to a rapid response to a new invasion. Isolated subpopulations were vulnerable to suppression; however, tributary subpopulations enhanced metapopulation persistence by serving as climate refuges. Water shortages driving changes in reservoir storage and subsequent warming would cause brown trout declines, but metapopulation QE was only achieved by re-focusing and increasing suppression. Our modeling approach improved our understanding of invasive brown trout metapopulation dynamics, which could lead to more focused and effective invasive species suppression strategies, and ultimately, maintenance of populations of endemic fishes.

Ecological Applications 2022;e2635. DOI: 10.1002/eap.2635. USGS FSP IP-133488. \| Abstract	April 2022	Understanding the relative strengths of intrinsic and extrinsic factors regulating populations is a longstanding focus of ecology and critical to advancing conservation programs for imperiled species. Conservation could benefit from an increased understanding of factors influencing vital rates (somatic growth, recruitment, survival) in small, translocated populations, which is lacking owing to difficulties in long-term monitoring of rare species. Translocations, herein defined as the transfer of wild-captured individuals from source populations to new habitats, are widely employed for species conservation, but outcomes are often minimally monitored, and translocations that are monitored often fail. To improve our understanding of how translocated populations respond to environmental variation, we developed and tested hypotheses related to intrinsic (density-dependent) and extrinsic (introduced rainbow trout <i>Oncorhynchus mykiss</i>, streamflow and temperature regime) causes of vital rate variation in endangered humpback chub (<i>Gila cypha</i>) populations translocated to Colorado River tributaries in Grand Canyon (GC), USA. Using biannual re-capture data from translocated populations over 10 years, we tested hypotheses related to seasonal somatic growth, and recruitment and population growth rates with linear mixed-effects models and temporal symmetry (TSM) mark-recapture models. We combined data from re-captures and re-sights of dispersed fish (both physical captures and continuously recorded antenna detections) from throughout GC to test survival hypotheses, while accounting for site fidelity, using joint live-recapture/live-resight (JLRR) models. While recruitment only occurred in one site, which also drove population growth (relative to survival), evidence supported hypotheses related to density-dependence in growth, survival, and recruitment, and somatic growth and recruitment were further limited by introduced trout. Mixed-effects models explained between 67 – 86% of the variation in somatic growth, which showed increased growth rates with greater flood pulse frequency during monsoon season. Monthly survival was 0.56 – 0.99 and 0.80 – 0.99 in the two populations, with lower survival during periods of higher intra-specific abundance and low flood-frequency. Our results suggest translocations can contribute toward the recovery of large-river fishes, but continued suppression of invasive fishes to enhance recruitment may be required to ensure population resilience. Further, we demonstrate the importance of flooding to population demographics in food-depauperate, dynamic, invaded systems.<br><br>

USGS FSP: IP-058150. \| Abstract	January 2015	Among salmonids, agonistic behavior is a means to increase an individual’s fitness by obtaining resources, defending resources, and establishing dominance over other individuals. Such behavior may also allow one species to gain growth or competitive advantage over others at a community level. In Scofield Reservoir, Utah, Bear Lake cutthroat trout (Oncorhynchus clarkii utah) and tiger trout (Salmo trutta, female X Salvelinus fontinalis, male) were added to the rainbow trout (O. mykiss) stocking regimen as potential biological controls for Utah chub (Gila atraria), creating an unusual complex of predatory species. A study evaluating the feeding ecology of the three trout species in the reservoir indicated substantial niche overlap between tiger trout and cutthroat trout at top tropic positions, and overlap between rainbow trout and Utah chub at lower positions, raising concern that community interactions may result in an overall decrease of trout condition. To evaluate the potential for negative interactions among these three species, we designed laboratory experiments to assess agonistic behavior. We determined differences in agonistic behavior between rainbow trout, cutthroat trout, and tiger trout with replicated, pair-wise treatments of one fish of each species together in a tank at different densities. We then observed the number of chases and contacts occurring between species, and considered density and relative length differences in our analysis. In all treatments rainbow trout initiated significantly more aggressive interactions than tiger trout or cutthroat trout (p<0.001). Feeding did not have a significant effect on agonistic behavior for any species; however differences in density and relative fish size appear to influence the degree of aggressive behavior. Though agonistic behavior has benefits, its tradeoffs may decrease rainbow trout condition in natural environments.

American and Eurasian beavers (<i>Castor canadensis; C. fiber</i>) are frequently translocated for reintroductions, to mitigate human-wildlife conflict, and as an ecosystem restoration tool. However, little is known about movement behavior of translocated beavers post-release, especially in desert rivers with patchy and dynamic resources. We identified space-use patterns of beaver movement behavior after translocation. We translocated and monitored nuisance American beavers in desert river restoration sites on the Price and San Rafael Rivers, Utah, USA, and compared their space use to resident beavers after tracking both across two years. Resident adult beavers were detected at a mean maximum distance of 0.86 ± 0.21 river kilometers (km; ±1 SE), while resident subadult (11.00 ± 4.24 km), translocated adult (19.69 ± 3.76 km), and translocated subadult (21.09 ± 5.54 km) beavers were detected at substantially greater maximum distances. Based on coarse-scale movement models, translocated and resident subadult beavers moved substantially farther from release sites and faster than resident adult beavers up to six months post-release. In contrast, fine-scale movement models using 5-minute location intervals showed similar median distance traveled between resident adult and translocated beavers. Our findings suggest day-to-day activities, such as foraging and resting, were largely unaltered by translocation, but translocated beavers exhibited coarse-scale movement behavior most similar to dispersal by resident subadults. Coarse-scale movement rates decreased with time since release, suggesting that translocated beavers adjusted to the novel environment over time and eventually settled into a home range similar to resident adult beavers. Understanding translocated beaver movement behavior in response to a novel desert system can help future beaver-assisted restoration efforts to identify appropriate release sites and strategies.

Submitted to Canadian Journal of Fisheries and Aquatic Sciences 77:1163-1171. \| Abstract	March 2020	The inclusion of passive interrogation antennas (PIA) detection data has promise to increase precision of population abundance estimates (). However, encounter probabilities are often higher for PIAs than for physical capture. If the difference is not accounted for, may be biased. Using simulations, we estimated the magnitude of bias resulting from mixed capture and detection probabilities, and evaluated potential solutions for removing the bias for closed capture models. Mixing physical capture and PIA detections (<i>p<sub>det</sub></i>) resulted in negative biases in . However, using an individual covariate to model differences removed bias and improved precision. From a case study of fish making spawning migrations across a stream-wide PIA (<i>p<sub>det</sub></i> ≤ 0.9), the coefficient of variation (CV) of () declined 39-82% when PIA data were included, and there was a dramatic reduction in time to detect a significant change in For a second case study, with only modest <i>p<sub>det</sub></i> (≤0.2) at randomly placed, smaller PIAs, CV( declined 4-18%. Our method is applicable for estimating abundance for any situation where data are collected with methods having different capture/detection probabilities.

North American Journal of Fisheries Management, Management Brief 42:109–114. DOI: 10.1002/nafm.10728. USGS FSP IP-133486. \| Abstract	January 2022	Research on fishes sometimes requires that individual fish be captured and subjected to invasive procedures multiple times over a relatively short time span. Electrofishing is one of the most common techniques used to capture fish and is known to cause injury to fish under certain circumstances. We evaluated the relationship of Columbia River Redband Trout <i>Oncorhynchus mykiss gairdneri </i>growth rates to the number of times captured via electrofishing and gastrically-lavaged during the summer of 2018 in a mountainous, headwater stream. We captured fish between two and seven times over the course of 86 days using continuous (smooth) DC backpack electrofishing. We observed no relationship between Redband Trout growth rate and number of times captured or gastrically-lavaged. While these findings contrast with hatchery electrofishing experiments, they may represent the greater resiliency of wild fishes. However, it appears researchers can use electrofishing and gastric lavage in cold waters at least once-per-month, and potentially up to twice-per-month, without greatly affecting the growth of wild Redband Trout.

USGS FSP: IP-118864. \| Abstract	January 2021	Stream habitat changes affecting primary consumers often indirectly impact secondary consumers such as fishes. Blooms of the benthic algae <i>Didymosphenia geminata</i> (Didymo) are known to affect stream macroinvertebrates, but the potential indirect trophic impacts on fish consumers are poorly understood. In streams of the Kootenai River basin, we quantified the diet, condition, and growth rate of trout, charr, and sculpin. In 2018, macroinvertebrate taxa composition was different between a stream with Didymo and a stream without, but trout diets, energy demand, and growth rates were similar. Trout abundance was higher in the stream with Didymo, but the amount of drifting invertebrates was higher in the stream without. In 2019, we surveyed 28 streams with a gradient of coverage. Didymo abundance was correlated only with the percent of aquatic invertebrates in trout diets and was not related to diets of charr or sculpin or condition of any species. Thus, we found no evidence for a trophic link between Didymo blooms and the condition or growth of trout, charr, or sculpin in mountainous headwater streams.

Conservation Biology: Conservation Practice and Policy 2021;3:e325. doi.org/10.1111/csp2.325. \| Abstract	January 2021	While the importance of reducing the impacts of non-native species is increasingly recognized in conservation, the feasibility of such actions is highly dependent upon the stage of invasion and the size of the ecosystem being restored. As such, invasive species management actions face three questions regarding the ultimate success of the action: (1) will the removal efforts be successful (i.e., will the invasive species remain absent), (2) will the native species respond positively to non-native species removal, and (3) how long after restoration activities can the native species be expected to reach a recovered state without further intervention. Here, we present the results of a multi-year, non-native brown trout (Salmo trutta) removal and native Bonneville cutthroat trout (Oncorhynchus clarkii utah) recovery in a small tributary in the Intermountain West, USA. We monitored trout populations for nine years prior to the onset of eradication efforts, which included two years of mechanical removal followed by two years of chemical treatment. Cutthroat trout populations were then seeded with low numbers of both eggs and juvenile trout. We monitored population demographics and estimated population growth rates and carrying capacities for both populations from long-term depletion estimate data, assuming logistic growth. Prior to eradication, brown trout populations fluctuated around their carrying capacity. Following brown trout eradication and initial seeding efforts, cutthroat trout populations have demonstrated exponential growth. Within five years, cutthroat trout have approached their estimated carrying capacity. Population projections suggest that cutthroat trout are between 70 and 80% of their carrying capacity and are likely to be at 90% of their carrying capacity within 10 years. Additionally, at least four age-classes are present including adults large enough to satisfy angling demand. These results demonstrate native trout species have substantial capacity to rapidly recover following the removal of invasive species in otherwise minimally altered habitats. While these locations are likely limited in extent individually, collectively they may serve as source populations for larger connected systems. In such cases, these source populations may provide additional conservation potential through biotic resistance.

Transactions of the American Fisheries Society 49: 443-461. \| Abstract	April 2020	Fishes that evolutionarily demonstrated a fluvial life history expression and migrated to spawning and rearing habitat using lotic corridors are increasingly impacted by fragmentation. The overall goal of this study was to identify the contemporary importance of mainstem connectivity and tributaries to maintaining life history expression, population structure, and viability of a large metapopulation of Bonneville Cutthroat Trout (BCT; <i>Oncorhynchus clarkii utah</i>) persisting in the Weber River, a highly fragmented Utah river. We used a multifaceted approach including active sampling, mark-recapture, passive PIT-tag detection, otolith microchemistry, and genetics. We collected BCT in all tributaries and the mainstem, encountering age-0 fish in three tributaries, indicating successful reproduction. In tributaries, the size structure was bimodal and consisted of smaller fish deemed to be resident and larger fish deemed to be fluvial, whereas all sizes and ages (≥ age-1) were present in the mainstem. We identified up to eight age classes; tributaries were dominated by ages 2 and 8, and the mainstem was dominated by ages 2, 5, 6, and 7. Tributary BCT had lower growth rates than BCT in the mainstem. We observed a surprising degree of fluvial life history expression, and fish also demonstrated very complex movement patterns across their life span. Average apparent survival (33%) was within the range estimated in similar studies for BCT, and resight rate was best explained by angler management regulations. The fact that BCT in the Weber River and tributaries still reproduce successfully in most years and are still able to grow into large, fluvial fish, suggests connectivity must be occasionally available despite considerable fragmentation. Therefore, this metapopulation may need little further human intervention if barriers to fish passage could be removed and thus connectivity could be improved and represents a high priority metapopulation for conservation, thus also highlighting the utility of our approach.

USGS FSP: IP-088494. \| Abstract	May 2019	Trout and char are a celebrated group of fishes and char hold a distinct place in the culture, nutrition, and economy of indigenous people. Their connections to ecosystems and people are profound and complex, and, in the United States, many are the state fish! Trout and char are speciose, and most taxa have evolved in response to major geological events. Today, relative to their historical distribution and abundance, the status of most trout and char in the United States is considered poor, and distributions have been dramatically reduced. In Canada, some of these fishes are depressed, while others are secure and support commercial and subsistence harvest. In the USA, for example, of the lineages of Oncorhynchus that we described, two are already extinct, five are listed as Threatened under the ESA, three are protected under Conservation Agreements or are considered ‘Species of Concern’, and those that remain have all undergone or are currently undergoing status assessments due to declines in abundance and distribution (Table 1). In contrast, of the four Salvelinus species we reviewed, only one is listed as Threatened under ESA, one is declining across its native range, and the other two have no range-wide legal conservation status and are considered stable. Arctic Char are even considered a sustainable food fish and are “of least concern” on the IUCN list.<br>Most species or sub-species face similar threats, although the most important limiting factors varied. Habitat degradation, genetic introgression, and the negative effects of non-native fishes (often by other trout) are the most influential threats to persistence. However, because all trout are obligate cold-water species, climate warming is also a ubiquitous threat. In addition, due to their extreme popularity as a game fish and recreational and economic value, trout and char enjoy broader management support than most species of fish and wildlife, particularly among those that are imperiled. As a consequence, there is a long history of trout and char management in North America. That history has changed over time from management focused on improving recreational angling opportunities to management that also emphasizes conservation and restoration of native populations. Common management strategies include hatchery propagation, harvest restrictions, habitat restoration (riparian, in-stream), improving passage and connectivity, and minimizing the impacts of non-natives (via removal, sterilization). Despite their imperiled status and persistent threats, the outlook is promising for many species, sub-species, and populations, largely because the most important limiting factors have been identified and because they are, in sum, a wildly celebrated group of fishes.

Ecology 94:356-367. \| Abstract	February 2013	Purposeful species introductions offer opportunities to inform our understanding of both invasion success and conservation hurdles. We evaluated factors determining the energetic limitations of brown trout (Salmo trutta) in both their native and introduced ranges. Our focus was on brown trout because they are nearly globally distributed, considered one of the world’s worst invaders, yet imperiled in much of their native habitat. We synthesized and compared data describing temperature regime, diet, growth, and maximum body size across multiple spatial and temporal scales, from country (both exotic and native habitats) and major geographic area (MGA) to rivers and years within MGA. Using these data as inputs, we next used bioenergetic efficiency (BioEff ), a relative scalar representing a realized percentage of maximum possible consumption (0–100%) as our primary response variable and a multi-scale, nested, mixed statistical model (GLIMMIX) to evaluate variation among and within spatial scales and as a function of density and elevation. MGA and year (the residual) explained the greatest proportion of variance in BioEff. Temperature varied widely among MGA and was a strong driver of variation in BioEff. We observed surprisingly little variation in the diet of brown trout, except the overwhelming influence of the switch to piscivory observed only in exotic MGA. We observed only a weak signal of density-dependent effects on BioEff; however, BioEff remained ,50% at densities .2.5 fish/m2. The trajectory of BioEff across the life span of the fish elucidated the substantial variation in performance among MGAs; the maximum body size attained by brown trout was consistently below 400 mm in native habitat but reached ;600 mm outside their native range, where brown trout grew rapidly, feeding in part on naive prey fishes. The integrative, physiological approach, in combination with the intercontinental and comparative nature of our study, allowed us to overcome challenges associated with context-dependent variation in determining invasion success. Overall our results indicate ‘‘growth plasticity across the life span’’ was important for facilitating invasion, and should be added to lists of factors characterizing successful invaders.

North American Journal of Fisheries Management 21:1211-1224. \| Abstract	August 2012	Despite numerous negative impacts, nonnative trout are still being stocked to provide economically and socially valuable sport fisheries in western mountain lakes. We evaluated relative performance and potential differences in feeding strategy and competitive ability of triploid versus diploid brook trout Salvelinus fontinalis in alpine lakes, as well as behavioral and performance differences of diploid and triploid brook trout in two controlled experimental settings: behavioral experiments in the laboratory and performance evaluations in ponds. Across lakes, catch per unit effort (CPUE) and relative weight (Wr) were not significantly different between ploidy levels. Mean sizes were also similar between ploidy levels except in two of the larger lakes where diploids attained slightly larger sizes (approximately 20 mm longer). We observed no significant differences between diploids and triploids in diet, diet preference, or trophic structure. Similarly, growth and condition did not differ between ploidy levels in smallerscale pond experiments, and aggressive behavior did not differ between ploidy levels (fed or unfed fish trials) in the laboratory. Independent of ploidy level, the relative performance of brook trout varied widely among lakes, a pattern that appeared to be a function of lake size or a factor that covaries with lake size such as temperature regime or carrying capacity. In summary, we observed no significant differences in the relative performance of brook trout from either ploidy level across a number of indices, systems, and environmental conditions, nor any indication that one group is more aggressive or a superior competitor than the other. Collectively, these results suggest that triploid brook trout will offer a more risk-averse and promising management opportunity when they are stocked to these lakes and elsewhere to simultaneously meet the needs for the sport fishery and conservation objectives.

USGS FSP: IP-058204 \| Abstract	February 2018	Brown trout are one of the most pervasive and successful invaders worldwide and are ubiquitous across the Intermountain West, USA (IMW). This species is the foundation of extremely popular and economically significant sport fisheries despite well-established negative effects on native fishes and ecosystems, resulting in very challenging, and often opposing, conservation and management goals. Herein, we review the direct (e.g., competition and predation) and indirect (e.g., disease vectors) pathways through which brown trout across the IMW have posed a threat to native species. We discuss the importance of brown trout as economically and culturally important fisheries, especially in novel tailwater ecosystems created by damming. To this end, we surveyed 26 experts from 8 states across the IMW to document the relevance of novel brown trout fisheries in 58 tailwaters and found brown trout are thriving in these novel ecosystems, which are often unsuitable for native fishes. We discuss the challenging interplay between protecting native species and managing novel brown trout fisheries. Notably, the future of exotic brown trout in the IMW is shifting as the prestige of native fisheries is growing and many non-native eradication efforts have occurred. The future of exotic brown trout in the IMW, will depend on the nexus of public sentiment and policy, the effectiveness of eradication efforts, and the effect of climate change on both the native fishes and exotic brown trout.

USGS FSP: SPDS: IP-053259. \| Abstract	June 2014	Size dimorphism in fish populations, both causes and consequences, has been an area of considerable focus; however, uncertainty remains whether size dimorphism is dynamic or stabilizing and about the role of exogenous factors. Here, we explored patterns among empirical vital rates, population structure, abundance and trend, and predicted the effects of climate change on populations of arctic char (Salvelinus alpinus) in two lakes. Despite differences in underlying geology, population and lake size, the density of adult char was extremely similar between lakes (0.002-0.003 m-2), and both populations cycle between dominance by small (≤ 300 mm) and large (> 300 mm) char. Survival and growth rates were relatively high (40-96 %; approximately 0.1 g.day-1) and comparable to lower latitude relatives. Climate change scenarios resulted in temperatures closer to optimal and for a longer growing season. An increase in consumption rates (28-34 %) under climate change scenarios led to much greater growth rates (23-34 %). Higher growth rates predicted under climate change resulted in an even greater predicted amplitude of cycles in population structure as well as an increase in Ro (reproductive output) and decrease in Go (generation time). Collectively, these results indicate that arctic char populations are extremely sensitive to small changes in the number of ice-free days. We hypothesize that, years with a longer growing season, predicted to occur more often under climate change, produce elevated growth rates of small char and act in a manner similar to a “resource pulse”, allowing a sub-set of small char to “break though”, thus setting the cycle in population structure.

We conducted a ﬁeld experiment to assess the relationship between site-speciﬁc environmental factors and bull trout embryo survival and fry emergence timing. Survival from egg to hatch was negatively related to percent ﬁne sediment (<1 mm) in the redd and positively related to the strength of downwelling at spawning sites. Survival of eggs to fry emergence was also negatively related to ﬁne sediment, and the best statistical models included additional variables that described the rate of downwelling and intragravel ﬂow within the incubation environment. Fry emerged at an earlier stage in development from redds with high percentages of ﬁne sediment. Increased hydraulic conductivity via redd construction and selection of spawning sites with strong downwelling appear to enhance hyporheic ﬂow rates and bull trout egg survival, but early life-stage success may ultimately be limited by intrusion of ﬁne sediment into the incubation environment.

We combined several active and passive mark–recapture and resight techniques to assess migration rates and estimate survival for juvenile bull trout (70–170 mm total length).We evaluated the relative performance of multiple survival estimation techniques by comparing results from a common Cormack–Jolly–Seber (CJS) model, the less widely used Barker model, and a simple return rate (an index of survival). Juvenile bull trout of all sizes emigrated from their natal habitat throughout the year, and thereafter migrated up to 50 km downstream.With the CJS model, high emigration rates led to an extreme underestimate of apparent survival, a combined estimate of site fidelity and survival. In contrast, the Barker model, which allows survival and emigration to be modeled as separate parameters, produced estimates of survival that were much less biased than the return rate. Estimates of age-class-specific annual survival from the Barkermodel based on all available data were 0.218±0.028 (estimate±SE) for age-1 bull trout and 0.231±0.065 for age-2 bull trout. This research demonstrates the importance of incorporating movement patterns into survival analyses, and we provide one of the first field-based estimates of juvenile bull trout annual survival in relatively pristine rearing conditions. These estimates can provide a baseline for comparison with future studies in more impacted systems and will help managers develop reliable stage-structured population models to evaluate future recovery strategies.

Frequent Usage of Tributaries by the Endangered Fishes of the Upper Colorado River Basin: Observations from the San Rafael River, Utah. North American Journal of Fisheries Management, Management Brief. Online DOI: 10.1080/02755947.2013.785993. \| Abstract	May 2013	The importance of main-stem rivers and major tributaries to endangered Colorado River fishes is well documented, but the use and significance of small tributary streams remains poorly understood. Historically, these fishes probably used smaller tributaries for spawning, rearing, feeding, and refuge. Currently, the proliferation of nonnative species and altered flows may have affected tributary use by endangered fishes. In February 2008 and 2009, we installed a PIT-tag passive interrogation array (PIA) in the San Rafael River, Utah, approximately 2 km upstream from the confluence with the Green River, and another PIA approximately 60 km upstream from the Green River confluence. Using passive detections and active captures in the San Rafael River from 2008 to 2010, we detected 15 Colorado Pikeminnow Ptychocheilus lucius, 16 Bonytails Gila elegans, 20 Razorback Suckers Xyrauchen texanus, and five “undocumented” fish. Several endangered fishes were detected on multiple occasions and across years, oftenmoving into and out of the San Rafael River from distances up to 360 km away (range, 6–360 km). Our findings demonstrate the use and the potential importance of small tributaries and their fragile habitats to endangered fishes.

Annual Variation of Spawning Cutthroat Trout in a Small Western USA Stream: A Case Study with Implications for the Conservation of Potamodromous Trout Life History Diversity. North American Journal of Fisheries Management 34:1033-1046. USGS FSP:IP-050825. \| Abstract	January 2014	Little is known about the variability in the spatial and temporal distribution of spawning potamodromous trout despite decades of research directed at salmonid spawning ecology and the increased awareness that conserving life history diversity should be a focus of management. We monitored a population of fluvial–resident Bonneville Cutthroat Trout Oncorhynchus clarkii utah in a tributary to the Logan River, Utah, from 2006 to 2012 to gain insight into the distribution and timing of spawning and what factors may influence these spawning activities. We monitored Bonneville Cutthroat Trout using redd surveys with multiple observers and georeferenced redd locations. We documented an extended spawning period that lasted from late April to mid-July. The onset, median, and end of spawning was best predicted by the mean maximum water temperature during the first 13 weeks of the year (F = 130. 4, df = 5, R2 = 0.96, P < 0.0001) with spawning beginning and ending earlier in years that had warmer water temperatures prior to spawning. The distribution of redds was clumped each year and the relative density of redds was greater in a reach dominated by dams constructed by beavers Castor canadensis. Both dam failure and construction appeared to be responsible for creating new spawning habitat that was quickly occupied, demonstrating rapid temporal response to local habitat changes. Bonneville Cutthroat Trout appeared to establish and defend a redd for up to 2 d, and spawning most often occurred between similar-sized individuals. Spawning surveys for potamodromous trout are an underutilized tool that could be used to better understand the distribution and timing of spawning as well as determine the size and trends of the reproducing portion of populations of management concern. Without efforts to document the diversity of this important aspect of potamodromous trout life history, prioritization of conservation will be problematic.

DOI: 10.1111/eff.12710. USGS FSP IP-147035. \| Abstract	February 2023	Understanding the processes governing population regulation is important for effective conservation and management. Disentangling the relative role of density-dependent versus density-independent population regulation is often made difficult by the inability to control for abiotic or biotic factors, but long-term datasets are invaluable in this pursuit. We used a 14-year dataset from the Logan River, Utah to assess long-term trends in abundance and evidence of density-dependent and density-independent population regulation of Paiute sculpin (<i>Cottus beldingii</i>) across six sites. Additionally, we evaluated the feeding ecology of sculpin over four years. Sculpin densities generally increased from downstream to upstream, and the per capita rate of increase was negatively and significantly correlated with sculpin density at four of six sites. We also observed a negative relationship between per capita consumption and sculpin density, providing a potential mechanism for density-dependent population regulation. Sculpin displayed a generalist feeding strategy, and interannual differences in diet composition appeared to be influenced by interannual differences in flow, particularly years with higher magnitude flow. The observed spatial patterns in sculpin abundance throughout the watershed matched those of invasive brown trout (<i>Salmo trutta</i>), which are the top piscivore in the Logan River. Our results suggest sculpin populations are regulated largely by density-dependent processes and match those from other studies on sculpin population dynamics including a range of species and habitats that differ vastly in abiotic conditions.

Transactions of the American Fisheries Society 150:291–306. DOI: 10.1002/tafs.10291. USGS FSP IP-119395. \| Abstract	January 2021	Lahontan Cutthroat Trout (LCT) <i>Oncorhynchus clarkii henshawi</i> have experienced some of the most marked reductions in abundance and distribution of Cutthroat Trout. In Pyramid Lake, Nevada, USA the population of LCT has returned from the brink of extirpation, and although highly managed via stocking, is thriving, and has recently started to reproduce naturally. Our objectives were to determine: 1) if predator and prey remain tightly coupled, 2) whether LCT are food limited, and 3) the status of the LCT population with regard to the potential prey-based contemporary carrying capacity. We used a multi-faceted approach including intensive field fish sampling, bioenergetic modeling, cohort reconstruction, and comparisons of prey availability to consumption. We estimated the average population of LCT in Pyramid Lake is 1.2 million, average annual stocking is 650,000, and fish angled ranges from 5,000 – 14,000/yr (90% release rate). Driven by seasonal and size variation in consumption, individual annual consumption of LCT varied from 667 - 992 g/yr for small LCT (200 – 400 mm) and 2,388 - 3,057 g/yr for large LCT (> 400 mm). LCT are consuming on average, 14 – 63% of the standing crop of Tui Chub <i>Gila bicolor</i> annually, indicating that LCT are currently not exceeding their prey-based carrying capacity. LCT in Pyramid Lake remain tightly coupled to their primary native prey, Tui Chub, despite considerable changes to the ecosystem. This means managing for a robust population of LCT translates largely to managing for forage fish. This supply versus demand issue is a particular concern in Pyramid Lake given there is indication the density of Tui Chub is declining concordant with declining lake elevation. Given the conservation importance of this population of LCT, careful monitoring is critical; however “predation inertia” indicates effective short-term management in response to fluctuations in forage fishes is likely possible.

USGS FSP IP-129828. \| Abstract	August 2021	Effects of climate change-driven disturbance on lake ecosystems can be subtle; indirect effects include increased nutrient loading that could impact ecosystem function. We designed a low-level fertilization experiment to mimic persistent, climate change-driven disturbances (deeper thaw, greater weathering, or thermokarst failure) delivering nutrients to arctic lakes. We measured responses of pelagic trophic levels over 12 years in a fertilized deep lake with fish and a shallow fishless lake, compared to paired reference lakes, and monitored recovery for six years. Relative to pre-fertilization in the deep lake, we observed a maximum pelagic response in chl <i>a</i> (+201%), dissolved oxygen (DO, -43%), and zooplankton biomass (+88%) during the fertilization period (2001-2012). Other responses to fertilization, such as water transparency and fish relative abundance, were delayed, but both ultimately declined. Phyto- and zoo-plankton biomass and community composition shifted with fertilization. The effects of fertilization were less pronounced in the paired shallow lakes, because of a natural thermokarst failure likely impacting the reference lake. In the deep lake there was (a) moderate resistance to change in ecosystem functions at all trophic levels, (b) eventual responses were often non-linear, and (c) post-fertilization recovery (return) times were most rapid at the base of the food web (2-4 years) while higher trophic levels failed to recover after 6 years. The timing and magnitude of responses to fertilization in these arctic lakes were similar to responses in other lakes, suggesting indirect effects of climate change that modify nutrient inputs may affect many lakes in the future.

Canadian Journal of Fisheries and Aquatic Sciences 79: 1–16. dx.doi.org/10.1139/cjfas-2021-0228. USGS FSP IP-125267. \| Abstract	February 2022	Reservoirs are one example of novel ecosystems which have developed into popular sport fisheries; these systems are also becoming seasonal refuges for migratory birds including piscivorous species such as the American white pelican (<i>Pelecanus erythrorhynchos</i>). We determined (1) the proportion of Bonneville cutthroat trout (<i>Oncorhynchus clarkii utah</i>) and other species consumed by pelicans, (2) whether pelicans have an adverse effect on cutthroat trout spawning movement, and 3) the relative importance of pelican predation toother sources of fish mortality on Strawberry Reservoir, Utah, USA. Greater than 85% of the pelican diet samples consisted of Utah sucker (<i>Catostomus ardens</i>), 6% were Utah chub (<i>Gila atraria</i>) and 3% contained cutthroat trout. We estimated pelicans consumed £ 2,600 individual cutthroat trout (~ 1% of population) in contrast to over 42,000 sucker, 19,000 chub, and > 6,000 crayfish. Bird-related mortality rate ranged 1 – 6% for PIT-tagged adult cutthroat trout and 4 – 16% for stocked subadult cutthroat trout. Pelicans primarily consume abundant non-game fish, thus any management action taken to control pelican predation would need to be carefully weighed against the benefits of non-game fish removal and the protected status of pelicans.

USGS FSP IP-139190. \| Abstract	July 2023	Submerged macrophyte communities are prevalent in low-gradient rivers around the world and interact with rivers and their biota in complex ways; the net effect of these interactions on trout habitat provision remains poorly understood. We used snorkel surveys and bioenergetics to study trout habitat selection and potential mechanisms driving habitat selection in the submerged macrophyte-rich Henrys Fork, ID, USA. At smaller spatial scales (i.e., individual microhabitats), we hypothesized trout would select for locations with more submerged macrophytes that provide overhead cover from predators, drifting macroinvertebrates as food, and lower swimming costs. In contrast, we found individual trout selected for microhabitats without submerged macrophytes (, with deeper water ( and with greater bioenergetic potential (. At larger spatial scales (i.e., reach-scale), submerged macrophytes acted as a living substrate, indirectly creating a riverscape of complimentary microhabitats by increasing depth (), bioenergetic potential (), and by influencing reach-scale ecosystem dynamics which modulated trout habitat selection. Our study improves understanding of the complex relationship between submerged macrophytes and trout habitat, explaining conflicting results among previous studies and revealing potential management actions to improve trout productivity. Continued study of abiotic and biotic processes across multiple scales may continue to reveal unexpected scale-dependent effects and mechanisms controlling trout habitat quality, quantity, and preferences.

The potential for nongame fish species to explode with detrimental effects on sport fisheries in Utah has prompted managers to shift some stocking programs from exclusively rainbow trout, to include tiger trout and/or Bear Lake cutthroat trout as potential biological controls. However, inter-specific interactions among this unusual complex of predatory species are not well understood, and there is concern that the overall effect may be a decrease of overall trout condition. In Scofield Reservoir rainbow trout niche space overlaps substantially with Utah chub (nongame), indicating a similar trophic position. Large tiger trout and cutthroat trout occupy top trophic positions indicating considerable niche overlap and possibly direct competition for food and space. To evaluate the potential for negative interactions among these three species, we designed laboratory experiments to assess agonistic behavior. Differences in agonistic behavior between rainbow, cutthroat, and tiger trout were determined with replicated, pair-wise treatments of one fish of each species together in a tank. We then observed the number of chases and contacts occurring between species. In all treatments rainbow trout initiated significantly (p <<0.000) more aggressive interactions (primarily chases) than tiger or cutthroat trout. Feeding (pre-post) did not have a significant effect on agonistic behavior for any species; however relative differences in fish size did appear to influence the outcome of the interaction for tiger trout. Understanding agonistic behavior provides important information for determining niche overlap between, and resource availability for, these sympatrically stocked species.

Invited paper, 68th Annual Meeting of the Society for Range Management, Sacramento, CA 31/01/2015.	January 2015	Species distribution models (SDM) predict that areas with climate suitable for sagebrush ecosystems will shift northwards and shrink in size over the next century due to global warming. Our analysis agrees with dramatic loss of total area suitable for sagebrush predicted by previous SDMs, but we show that these losses will not occur evenly over land management agencies.

Exploring movement patterns of an endangered minnow in a fragmented desert river. 54th Annual Meeting, Desert Fishes Council, St. George, UT, 16-20 November 2022. Oral Presentation.	November 2022	The overall goal of the study is to better understand the movement ecology of Rio Grande Silvery Minnow, and identify possible drivers of movement patterns. A greater understanding of how river fragmentation impacts the movement patterns of imperiled fishes can help guide and better inform the management of desert riverscapes to ultimately achieve self-sustaining populations of native fishes.

Oral Presentation, RiversEdge West, 20^th Annual Conference, "Learn from the last 20 years and plan for the next". Hybrid: Grand Junction, CO.	February 2022	We discuss the importance of the natural flow regime for functioning riverine ecosystems and provide examples from four tributaries to the middle Green River, a major headwater branch of the Colorado River. Despite decades of intense management, endangered species continue to lack self-sustaining populations and other imperiled native species have been extirpated from over half their ranges, which begs the question of whether water development and fish conservation can be balanced?
