Modeling Bat Habitat Use Across Big South Fork National River and Recreation Area (BISO): Potential Effects of Prescribed Fire	May 2016	We will study year-round bat activity on BISO and relate species presence and activity to environmental conditions such as temperature and rainfall, forest type, forest structure, and management history. Seven prescribed fires have been conducted since 2005 and these sites will be sampled as will a number of unburned sites. We will use these data to model the potential effects of BISO’s fire management plan on habitat suitability for various bat species inhabiting the park.	While prescribed fire is known to maintain forest health and minimize disease, little is known about its impact on bat activity. Past studies suggest the reduction in vegetation density as a result of burning may increase access and foraging efficiency. As the Big South Fork National River and Recreation Area (BISO) Fire Management Plan is revised, this project aims to provide data on seasonal bat use and habitat associations that will enhance the plans’ ability to safely and productively manage forests with prescribed fire for rare and endangered bats occupying the area. Currently, acoustic detectors are being used to assess bat presence and activity throughout the annual cycle on BISO by simultaneously monitoring activity levels in forest sites with varying burn histories and adjacent unburned sites.<br>To date two seasons of summer sampling have been completed, with a second season of winter sampling in progress. Habitat structure and composition were assessed and temperature recorded at each site, with metrological data obtained from a regional weather station. A total of 4079 bat passes at 66 sites were recorded during the 2014 summer season and identified to species when possible.<br>General linear model procedures were then used to examine the effects of varying burn histories, and forest composition and structure on summer bat presence and activity. Preliminary analyses indicate that bat presence and total activity are significantly greater in burned sites compared to unburned sites, and show a correlation between increased activity and lower stem densities. Additional analyses among burned sites suggest that interactions between forest composition and burn history affect forest structure and activity levels.
Modeling Winter Habitat Use of Whooping Cranes in the Eastern Migratory Population	December 2016	We have identified a need to assess wintering ecology of cranes so as to better predict the types of habitats they may use and the quantity and quality of habitats that may be available throughout the EMP. This is pertinent not only to understanding winter ecology but also to elucidate the linkages that exist between winter habitat quality and subsequent reproductive success. If time and funding permit (or as subsequent research efforts) we also would seek to better understand food quality and availability at wintering sites, wintering movement patterns, and territoriality for breeding pairs or family groups during the nonbreeding season. <br><br>The goal of the research is to enhance our understanding of wintering habitat use of whooping cranes so as to better inform decision-making as it relates to wintering habitat assessment as well as the development and protection of current or alternative wintering sites. Our objectives are to (1) quantify wintering habitat use of adult whooping cranes at the patch and landscape scales from monitoring data collected for the EMP between 2001-2013, (2) using habitat models created in objective 1, predict suitability of potential wintering areas east of the Mississippi River, (3) solicit expert opinion to further inform the development of predictive habitat models for novel wintering sites east of the Mississippi River, and (4) use a structured decision making framework to evaluate possible wintering habitat locations as identified in objectives 2 and 3.	The reintroduced Eastern Migratory Population (EMP) of Whooping Cranes (Grus americana) has reached recovery goals of 25 breeding pairs and 100 individuals in the population, but is not yet reproducing successfully to be self-sustaining. Unlike the growing population of Whooping Cranes in the central flyway that winter in coastal marshes of the Gulf of Mexico, the EMP has an expansive winter range that includes many agricultural areas in the eastern United States. It is unclear if quality of winter habitat is contributing to the population’s lack of reproductive success. The general winter and migratory range of this population is known, but the specific habitats, behaviors, and patterns of movement are not well-understood. The goals of this study are to assess (1) daily movements and habitat characteristics of wintering areas, and (2) migration routes and habitat characteristics of stopover sites. <br><br>Field data were collected during winters 2014-15 and 2015-16, and were analyzed during 2016-17. On average, Whooping Cranes used a daily home range of 3.4 km2 during winter 2014-15, and 4.1 km2 during 2015-16. Whooping Cranes were most often observed using open landscapes including cultivated crops for foraging, and open water habitats for foraging and loafing. Protected areas and areas with hydric soil were favored by wintering Whooping Cranes, while forested areas were avoided. <br>Preliminary analyses of satellite telemetry data collected during migration show similar habitat preferences on stopover sites. Additionally, Whooping Cranes do not seem to use the exact migration routes from year to year, but may show fidelity to stopover sites. Ongoing analyses will investigate differences in migration timing, distance, and use of stopover sites. A better understanding of the winter and migration habitat used by Whooping Cranes in the EMP will aid in management of current wintering areas, direct conservation efforts of unprotected lands, and will inform future research on the overall success of this population.
Economic Impacts of Feral Hogs on South Carolina’s Agriculture Submitted to the South Carolina Farm Bureau	May 2016	A quantitative and qualitative assessment of feral hog damage to South Carolina farms.	Wild Hogs (Sus scrofa) are an invasive species presently found in the United States in at least 36 states, including South Carolina, and can negatively impact native species, agricultural systems, domestic livestock, and human health. This project aimed to assess the feasibility of a technical assistance program using trap materials through the United States Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) for landowners in South Carolina. We identified five NRCS Environmental Quality Incentives Program (EQIP) eligible landowners with significant wild hog damage on their property and provided technical assistance and materials for camera-activated corral traps from June 2014 to May 2015. During the project, landowners trapped 30 wild hogs, and the camera-activated corral traps took a total of 5,080 pictures with non-target species encountered in 85.8% of pictures. Non-target species encountered in the traps included White-tailed Deer (Odocoileus virginianus), Raccoons (Procyon lotor), Eastern Cottontail rabbits (Sylvilagus floridanus), and Opossums (Didelphis virginiana). The results of this project were communicated to NRCS field personnel and other professionals through two wild hog management workshops. Additionally, this project aimed to examine the prevalence of six wild hog diseases in South Carolina as well as the relationship between disease prevalence and age class, sex, and geographic location. From 2007-2014, wildlife biologists from USDA Wildlife Services collected blood and nasal swab samples from wild hogs in South Carolina to test for classical swine fever, swine brucellosis, pseudorabies virus, porcine circovirus, porcine reproductive and respiratory syndrome, and swine influenza virus. Wild hogs tested positive for every disease except classical swine fever in at least one county of South Carolina from 2007-2014. The presence of these pathogens in the state’s wild hog population indicates that wild hogs may be disease reservoirs with the potential to transmit diseases to domestic livestock or native wildlife.
Innovative Approaches to Manage and Reduce Feral Hog Damage to Agronomic Systems, Woodlands, and Ecosystem Services	September 2015	In response to growing concerns about the economic and ecological impact of feral hog populations among federal, state, and local leadership within the state of South Carolina, Clemson University seeks to develop novel management approaches to reduce invasive feral hog damage. This project will utilize public surveys to identify lands/stakeholders with severe feral hog damage within the state. These sites will serve as pilot areas to further develop innovative camera trap tools (in addition to traditional methods) to manage and reduce feral hog damage. This project will allow us to assess the effectiveness of a technical assistance and cost-sharing program (materials and equipment) to reduce feral hog damage on EQIP eligible producers’ property. The results of this project will be used to develop a set of “best practices” management recommendations that will be communicated to natural resource managers, community members and the NRCS. Based on the results of this project, we will also implement meetings and training events to allow landowners to be trained in the most effective feral hog management techniques.

Development of a seabird colony atlas for the southeastern US	December 2013	There is no current atlas or database of seabird nesting sites for the entire southeastern U.S. (NC, SC, GA, Atlantic Florida). The Deepwater Horizon oil spill highlighted the critical need for such a product in each coastal region of the U.S. An atlas also would be valuable for marine spatial planning issues including but not limited to sighting wind turbines, scheduling and sighting sand-dredging and beach nourishment operations, managing recreation and access, and land/marine conservation planning. Therefore, our objective is to develop a register (data, meta-data) and atlas (spatial inventory) of colony sites used by breeding seabirds throughout the study area. The register and atlas will be available on-line and would also serve as the foundation for future development of a dynamic and continuing database that would support the R4 Inventory & Monitoring Network.

Eastern Brown Pelicans: Dispersal, Seasonal Movements and Monitoring of PAHs and Contaminants in the Northern Gulf of Mexico	November 2019	The Gulf of Mexico (GOM) contains a high density of oil and gas infrastructure and coastal development. It also has a rich assemblage of nearshore and pelagic seabirds. The region is of year-round importance to seabirds, including local breeding populations and breeders from distant locations that occur within the Gulf throughout the year. Because of its distribution patterns, behavior, and known sensitivity to chemical and oil contaminants exposure, the Brown Pelican (<i>Pelecanus occidentalis</i>) is a good indicator of species-level impacts from interactions with coastal and marine development. The species is widespread throughout the northern GOM and common during all phases of the annual cycle. Despite the species’ long history as a focus for conservation and restoration efforts, much of the information required to understand pelican population dynamics and habitat requirements (i.e<i>.,</i> adult and fledgling mortality, dispersal, site fidelity, diet composition, foraging behavior, migration patterns, and nonbreeding habitat use) remains unknown or is poorly understood.<br><br>In this study, we used several unique research avenues to address questions regarding movement, habitat use, physiology, and reproductive ecology of brown pelicans.

Reproductive Ecology of Wilson's Plover	December 2013	Wilson’s Plover is a medium-sized plover associated strictly with coastal areas. The US Shorebird Conservation Plan list Wilson’s Plover as a “species of high concern” in their prioritization of shorebird species according to relative conservation status and risk. Wilson’s Plovers are listed as state threatened in South Carolina. SCDNR surveys from 2009 -2011 suggest approximately 300 pairs nest in SC and they are rare on beaches with development. The major threat to the species in US is destruction of breeding habitat by development of beachfront areas. On undeveloped barrier islands, human disturbance can cause nest loss and abandonment of sites. Because nests and chicks are camouflaged and cryptic, crushing by humans and vehicles on beaches can also cause lower reproductive success. Studies of feeding, activity budget, and habitat use have been conducted in Venezuela on their wintering grounds. Otherwise, little is known about most aspects of the life history of this species. Our objectives are to: (1) Determine nest success and factors affecting reproductive loss of Wilson’s Plovers at South and Sand Islands, Yawkey Wildlife Center, SC, (2) Determine nesting chronology of Wilson’s Plovers, and (3) Determine habitat used by Wilson’s Plover broods Determine brood behavior in response to presence of humans	None
Decision Support for Public Alligator Harvesting in Georgia, Florida, and South Carolina	June 2017	Regulations for public alligator harvesting in the states of Georgia, Florida, and South Carolina are based on an assessment of current-year alligator population size against statistically-estimated historical trends in abundance. However, mechanistic models offer certain advantages over statistical models in that (1) they may be able to better predict harvest outcomes that are outside of historical experience, (2) they facilitate the making of optimal harvest decisions based on threshold conditions tied to the biology of the species, not the population's past performance, and (3) they provide a straightforward way to account for biological uncertainty about the response of populations to harvest management. In this project, we will employ a structured decision making approach to consider the problem of public alligator harvesting in the three participating state agencies. The approach will explicitly recognize the policy differences (management objectives and regulatory options) among the agencies, but it will take advantage of regional commonalities in population biology, habitat relationships, and sampling characteristics in the development of a set of decision models. Under this design, we expect that efficiencies can be created because the model set can be informed and improved by data contributed by any agency, and the models may indicate uncertainties toward which agencies can coordinate focused research efforts.
Determining the Movement Patterns and Habitat Use of Seabirds to Support Marine Spatial Planning Along the Atlantic Coast	December 2012	We will use remote tracking technologies such as satellite transmitters and global location sensors to track movements and map use areas of individual seabirds along the Atlantic coast. We will target seabirds that are likely to use areas off of the mid-Atlantic coast. Data will allow us to better understand the link between multiple and widespread geographic regions such as the nearshore and pelagic zones of the mid- and south Atlantic US coasts and the islands and waters of The Bahamas and Caribbean. The proposed effort will build upon ongoing work by the PI.	Many species of seabirds breeding in the Caribbean occupy waters off the Atlantic and Gulf coasts of the US during some portion of the annual cycle. As marine spatial planning becomes a pressing issue in the region, data are needed to enhance our understanding of the seabird community in the South Atlantic Bight and the Gulf of Mexico. Although current ship-based and aerial surveys are the standard methods used to measure abundance and distribution of birds at sea, each is a population-based survey that provides information without regard to individual variability or colony of origin. We are deploying tracking devices to measure movement patterns of seabirds in the Caribbean, Gulf of Mexico, and Northwest Atlantic. Data from individual tracking efforts will allow us to assess variability in movements and use patterns, fidelity to specific marine locations, and the relationship between marine use areas and breeding locations and population trends at the breeding grounds. To date, we have collected tracking data from six species of pelagic seabirds in Mexico, Jamaica, the Dominican Republic, The Bahamas, British Virgin Islands, St Eustatius and Tobago in collaboration with federal agencies, and local Universities and NGOs. Our research builds upon tracking work we initiated in the Bahamas in 2008-2010 and also takes advantage of the Capacity Building project we initiated in the Caribbean. As such, we are closely collaborating with the University of the West Indies in advising M.S. student Hannah Madden in St Eustatius for the study of the breeding biology and spatial ecology of the local population of vulnerable Red-billed Tropicbird (Phaethon aethereus). In April of 2016, we conducted a pilot study to deploy GPS loggers on breeding adults; based on this effort we will be able to improve our tracking effort during the winter of 2017. These data will complement our earlier studies on the connectivity of Caribbean seabird species. Details on each project, including a complete list of sponsors and collaborators, can be found at www.atlanticseabirds.org
Building International Capacity for Seabird Conservation	December 2012	The coastal wetlands and islands of the Caribbean and the Gulf of Mexico and the surrounding marine areas provide essential habitats for migratory and resident waterbirds (seabirds, shorebirds and waterfowl) and many other birds. They are increasingly threatened by coastal development, sea-level rise and invasive species, amongst other threats. The impacts of these threats were compounded by the Deepwater Horizon (DWH) oil spill, which affected aquatic birds directly through oiling and indirectly through damage to breeding habitats and feeding grounds. The goal of this project is to compensate for lethal and sublethal damages to Caribbean and Gulf of Mexico seabird/waterbird meta-populations and their habitats caused by the DWH oil spill by building long-term, in-country capacity to address threats and effectively manage and conserve species and habitats. We will (1) implement immediate conservation projects at high-priority sites that also will serve as demonstration projects for a later capacity-building training workshop, (2) train key individuals (including protected area managers, scientists, and their partners who will themselves implement projects and act as trainers) during a multi-day capacity-building workshop, (3) support trained individuals by developing and implementing projects (to be supported by a small grants program) as well as long-term funding proposals. These activities will mitigate the effects of the DWH and permanently increase the capacity to address other short and long-term threats. The main activities will focus on assisting local practitioners to implement practical conservation activities addressing regional priority needs.	None
Response of nearshore seabirds to the Deepwater Horizon Oil Spill	December 2011	This research will be a component of the NRDA avian injury assessment at the Gulf of Mexico – Mississippi Canyon oil spill. We will oversee the capture, sampling, and placement of transmitters on targeted shorebirds, seabirds, and beach nesting birds. Telemetry will allow monitoring to determine the rate of mortality in sublethally oiled birds. The primary species of interest are brown pelican (Pelecanus occidentalis), royal tern (Sterna maxima), and black skimmer (Rynchops niger). Satellite tags with activity sensors, VHF tags with mortality switches, microGPS tags, or geolocators will be deployed to evaluate survival and movement. The type of device deployed will be chosen based on the body mass of the individual. The mass of the device will not exceed 3% of the individual’s body mass. Whenever possible, carcasses of deceased birds also will be retrieved. Health assessments of individuals that are “sub-lethally” oiled also will be conducted. Parameters to be measured will include but not be limited to total polycyclic aromatic hydrocarbons (PAHs), glucose concentrations, and inorganic phosphorus. Data collected will be used to estimate mortality rates of adult birds, determine movement patterns, and determine habitat use patterns.	None
Herpetofaunal spatial ecology in South Carolina	December 2025	The southeastern United States is a biodiversity hotspot, and South Carolina has a broad diversity of species. However, many species of herpetofauna are overlooked, despite their ecological importance. This research project aims to address what we know and can learn about herpetofauna from a spatial ecology perspective. This will fill in gaps in knowledge about how land use affects herpetofaunal species, and what we can learn about their resource use and movement across the landscape in the face of changing land use. This research is a collaboration including USGS SC CFWRU, South Carolina DNR, and potentially the Nemours Foundation. Findings from this research will help support conservation actions by characterizing spatial patterns of species and their correlation with diverse land uses.

Foraging Ecology of Seabirds in Relation to Commercial Shrimp Trawler Activity	December 2008	Population dynamics of seabirds have been linked to availability of bycatch discarded from commercial fishery operations. South Carolina supports a substantial commercial shrimping industry that operates primarily in inshore waters where locally breeding Brown Pelicans (Pelecanus occidentalis), Laughing Gulls (Larus auritus), Royal Terns (Sterna maxima), and Sandwich Terns (Sterna sandvicensis) forage. We examined the relative abundance of these seabirds at shrimp trawlers during the breeding season, measured the consumption fate of fish species collected as bycatch and subsequently discarded, and measured the energy density and proximate composition of these discarded items. Trawlers were attended regularly by all four locally-breeding seabirds out to 30 km from colonies. Laughing Gulls were the most frequently observed followed by brown pelicans, royal terns, and then sandwich terns. Seabirds captured ca. 70% of experimentally discarded items from shrimp tralwers. Brown pelicans consumed more discards than predicted based on their frequency while the other species each consumed fewer discards than predicted based on their frequency. Seabirds selected smaller items compared to larger items, and selected benthic fish that typically would not be available to this suite of seabirds. Energy density of common discards ranged from 2.9 – 4.1 kJ/g wet mass and there appeared to be no difference in the energy density of the pelagic or demersal fish we measured. Our data suggest that all four locally breeding seabirds forage at trawlers frequently enough that changes in the size of the shrimp fleet would have the potential to affect their foraging ecology.

Foraging Ecology and Health Assessment of American Oystercatchers throughout the Annual Cycle	December 2008	The U.S. Shorebird Conservation Plan identified the eastern race of the American Oystercatcher as a species of extremely high priority. The subspecies breeding population is < 3,000 and declining. South Carolina supports ca. 400 breeding pairs (ca. 60% nest in the Cape Romain Region; CRR) and ca. 35% of the wintering oystercatchers along the east coast (ca. 50% of these birds are in the CRR). Many of the oystercatchers that breed in the CRR also winter there (i.e., are residents), although nonresidents from breeding sites as distant as New England also winter there. Preliminary data also suggest that reproductive success ranges widely among habitat types within the CRR. Chronic failure occurs along the Atlantic Intracoastal Waterway (AICW) while success is variable on estuarine islands. The former habitat type may act as an ecological trap, while the latter may be a source. This study will identify foraging areas of breeding oystercatchers and of wintering adults throughout the CRR, measure use of shellfish beds, link foraging ecology with reproductive success, and define diet of breeding adults and wintering adults via behavioral observations.

Protection and Management of Seabird Colonies in South Carolina	December 2010	Seabirds nest in colonies on approximately nine islands along the coast of South Carolina. These islands are characterized by sandy beaches, absence of mammalian predators, low vegetation, and an upland that provides habitat for nesting shorebirds and colonial seabirds. One of the main challenges faced by managers at these colonies is balancing the needs of breeding and migratory birds with those of island visitors. The goal of the study is to monitor seabirds and collect baseline measures of breeding parameters to better evaluate the health and condition of seabird populations at protected nesting islands. The first objective of this study was to map habitat use by seabirds during the breeding season. To meet this objective we conducted intertidal surveys during the 2007 and 2008 breeding seasons to identify areas of high bird use. We conducted 12 surveys at Crab Bank, 18 surveys at Bird Key Stono, and 17 surveys at Deveaux Bank. We also measured habitat characteristics of the intertidal zones of these three islands. Over 30 species of waterbirds were recorded during these surveys, and data suggest that use varies spatially and temporally during the breeding season. Our next objective was to measure reproductive and behavioral parameters of breeding seabirds. In 2007 and 2008 we measured Black Skimmer (Rynchops niger) nest success at three nesting islands. Across all colonies and years, mean hatching success was 0.45 ± 0.26 chicks hatched per nest and mean productivity was 0.27 ± 0.21 chicks fledged per pair. Temperature loggers were placed in 108 nests to determine the effect of temperature patterns during incubation on nest success; these data are being analyzed. Brown Pelican (Pelecanus occidentalis) reproductive parameters were monitored during all years of the study. Across all colonies and years, mean hatching success was 2.0 ± 0.26 chicks hatched per nest and mean productivity was 1.48 ± 0.26 chicks fledged per pair. We recorded provisioning and attendance behavior of pelicans at the Deveaux Bank colony in 2008. These data are being analyzed and will be comparable to those published by Sachs and Jodice (2009) from Crab Bank. Our final objective was to determine condition and health of seabird populations. To meet this objective, we monitored health parameters of 43 nestling Brown Pelicans to establish reference values and investigate the role of ticks nestling health. The field work portion of this study was completed in October 2008. A final report was submitted in June 2010 and the dissertation is currently being prepared for defense.	None
Reproductive Success of Painted Buntings on Golf Courses in South Carolina,	December 2011	The Painted Bunting (Passerina ciris) has been placed on the Audubon WatchList due to a steady decline since 1966. The reason for the decline is unknown, but habitat loss is suspected to be the predominant factor. Painted buntings have established 2 breeding populations in the US, one in the southwest and one in the coastal southeast. The southeastern distribution ranges from southern North Carolina to northern Florida. This coastal population often uses salt marshes for foraging and nests in dense shrubbery or Spanish moss. The lowcountry of South Carolina supports a large breeding population of Painted Buntings. This area has experienced substantial development in the form of golf courses and associated communities. Thus, shrub habitat typically used for nesting by Painted Buntings is being removed and altered, and wetland systems often used for foraging are being modified. This changing landscape presents management concerns for Painted Bunting populations. During the breeding season of 2008 and 2009, we searched Spring Island and Chechessee Creek Club in Okatie, SC for nests. Once found, nests were monitored until they succeeded or failed. We recorded signs of success or failure, nest height, nest plant species, and GPS location. During these two seasons we located 18 nests. Of these, 13 were located in shrub habitat and the remainder in trees. Three nests occurred in clumps of Spanish moss. Most nests were located during incubation and most failed although causes of failure were difficult to document. During the 2010 breeding season, we surveyed the breeding bird community of 24 golf courses along the coast from Beaufort to Hilton Head, SC. On each golf course, point counts were conducted on a 440m grid with 200m detection radius. Points were selected for use if any portion of in-play area of the golf course fell within the 200m radius of the point. There, all birds seen and heard were tallied. Each course was surveyed twice in a morning, and twice throughout the season. Upcoming analyses will use GIS data to examine point- and golf course-scale landscape characteristics with respect to the breeding bird community. Painted buntings will receive special focus in our results. We will assess vegetation characteristics with presence/absence of painted buntings and additional species of concern, thus lending insight to possible land management techniques for southeastern coastal golf courses.

Seabird Productivity in Cape Romain National Wildlife Refuge	December 2010	CRNWR is one of the most important areas for beach-nesting birds in SC. Marsh Island and White Banks support a diverse array of seabird species and are 2 of only 5 large seabird sanctuaries in the State. Additionally, CRNWR has tern and skimmer nesting on the barrier island beaches of Lighthouse Island, Cape Island and Raccoon Key. During the past 5 years, these barrier islands are often the only barrier islands in SC that support seabird nesting. In 2007, these beaches supported 56% of SC’s black skimmers. Although least terns nest on roof tops and artificial sites, 75% of the least terns that nested on beaches in SC, nested in CRNWR. Although nest counts document the importance of CRNWR for seabird nesting, observations by SCDNR and CRNWR staff in the past 3 years suggest that reproductive success on the barrier islands in CRNWR is very low. Seabirds often abandon nest sites shortly after egg laying and fledglings are not observed. The goal of this project is to monitor seabird nesting on Cape Island, Lighthouse Island and Raccoon Key to document reproductive success and help identify causes of colony abandonment and nest loss.

South Atlantic Information Resources: Data Search and Literature Synthesis for Seabirds	December 2010	A recent synthesis of oceanographic data for the South Atlantic Bight is lacking and this is particularly true for avian taxa in this region. Clapp et al. (1982) composed distributions of marine birds from records dating until the early 1980s but no comprehensive synthesis has been conducted since. The need for such a synthesis is warranted given the increase in human activity within this zone (e.g. commercial and recreational fisheries) and proposed or experimental activities focused on energy development. Furthermore the region supports a wide array of breeding and migratory seabirds, many of which are declining or have population trends of unknown trajectories. In many cases research on these species has been minimal and not always made available in easy-to-access outlets. I propose to synthesize the existing knowledge on distribution and ecology of seabirds in the South Atlantic Bight. Data gaps will be identified and areas for future research highlighted. The work will build upon current efforts of the PI to increase the knowledge-base of seabird ecology along the South Atlantic US coast	None
Enhancing Productivity of American Oystercatchers	May 2012	The American oystercatcher (Haematopus palliatus) occurs in coastal habitats from Massachusetts to Florida, although breeding populations appear to be declining in states south of Virginia. The central coast of South Carolina is a critical region for this species. South Carolina supports ca. one-third of the wintering oystercatcher population along the Gulf and Atlantic coasts. South Carolina also supports ca. 400 breeding pairs of oystercatchers and ca. 25% of these are in the Cape Romain region (CRR; i.e., Cape Romain NWR and areas adjacent to it). It appears, however, that productivity in this area may be relatively low. Research conducted by the PIs in the CRR found that fledging success of 99 pairs during 2006 and 2007 was ca. 0.25 chicks/pair. Nest loss was attributed primarily to natural flooding (spring storms and spring high tides that often coincide with incubation) anthropogenic flooding (boat wakes along the Atlantic Intracoastal Waterway [AICW]), and predation. We also found that renesting attempts were common, with even third and fourth attempts occurring. This suggests that resources in the area were sufficient to induce pairs to remain and renest despite nest losses. We propose to increase nest success of oystercatchers in the CRR by reducing predation and by head-starting (i.e., artificial incubation of eggs). While the former will provide benefits specifically to the region, the latter will provide information on a management tool that will be applicable throughout the species breeding range. Our goal is to increase fledging success to 1.5 chicks/pair for 90 pairs. We will target 50 pairs for predator control and 40 pairs for headstarting. We also will monitor nest success and chick survival at these nests and others in the region. These efforts will build upon research conducted by the PIs.	None
Environmental and temporal patterns of larval fish communities and American Shad spawning in the lower Broad River	July 2025	Anadromous species, such as American Shad (<i>Alosa sapidissima</i>), are ecologically and economically important species in SC that migrate from the ocean to spawn in rivers. Accordingly, American Shad are particularly sensitive habitat fragmentation resulting from dam construction that block migratory pathways and are also being threatened by overfishing, flow alteration, and habitat loss. Due to these threats, the American Shad has been listed as a species of high conservation need on SCDNR’s State Wildlife Action Plan. Historically, anadromous species used much of the Broad River, but dams have since blocked upstream migration, resulting in the loss of spawning habitat for many species. In 2007, the construction of fish ladder at the Columbia Diversion Dam open access to 24 miles of potential spawning habitat for anadromous species, and species like the American Shad are passing through the fish ladder in increasing numbers. However, it is still unknown if or where spawning occurs between Columbia Diversion Dam and Parr Hydroelectric Dam (SCDNR personal communication). Therefore, this project aims to determine whether American Shad are spawning in this river section as well as identify potential spawning habitat sites. Site-specific information on spawning sites and larval fish habitat requirements are needed to better understand how larval and adult fish American Shad will respond to habitat alteration and provide manager with information needed to protect key spawning and nursery habitats. Additionally, environmental cues driving migration and spawning of shad are not well understood. Temperature and instream flow variation are thought to be the main factors driving American Shad spawning, migration, and recruitment. This project will also explore the effects of variation in temperature and river discharge on recruitment spawning and adult migration upstream.	The objectives of this project are to: 1) identify the temporal patterns of egg and larval fish abundance of the fish community to better understand when fish populations may be most sensitive to environmental disturbance such as large water releases; 2) determine if American Shad are spawning between the Columbia Canal Diversion Dam and Parr Reservoir; 3) identify potential spawning and nursery habitats for American Shad; 4) quantify the temporal pattern of the larval fish community in the lower Broad River. This project will deliver crucial information on spawning and migration activity of American Shad in the lower Broad River. Additionally, this project will provide managers with a better understand of temporal patterns of larval fish and the environmental variables driving these patterns in the lower Broad River. The results of this project will also allow managers to more effectively evaluate the potential benefits of the Columbia Fishway for American Shad and the impacts of different discharge regimes and environmental alteration on fish populations.

Health and Movement Patterns of Bahamian Seabirds	January 2010	Seabirds are sampled for avian influenza at colonies in the Exuma Cays, Bahamas. Geolocators are deployed on two seabird species, Audubon's Shearwater and White-tailed Tropicbird, to map annual movement patterns. These are the first efforts to map annual movements of seabirds from this region. Data will be used in conservation planning throughout the northwest Atlantic basin.	The foraging behavior and movement patterns of Audubon's Shearwater (Puffinus lherminieri) and White-tailed Tropicbirds (Phaethon lepturus) in the North Atlantic have not been studied directly. We attached geolocators equipped with a wet/dry sensor to 11 shearwaters and 13 tropicbirds with young chicks in June 2008 at the colonies in the Exumas, Bahamas. We retrieved two of the devices from shearwaters in July 2008 after a deployment period of ca. 5 weeks, 4 devices from shearwaters and 3 from tropicbirds in June 2009. During the breeding season both species frequented the northern Bahamas but shearwaters also were located south of Cuba. During winter shearwaters dispersed along the coast as far north as the northeastern U.S. Tropicbirds dispersed north but also were frequently located east of Bermuda and in waters towards the mid-Atlantic ridge. Additional devices will be deployed in 2010 and efforts to recover devices still at-large will continue. These locations represent the first annual movement data collected from seabirds in the Bahamas and broaden our view of their foraging range in the breeding and nonbreeding seasons.
Support of International Sea Eagle Projects	December 2010	Objectives: The objectives of this research work order are: 1. To support travel for field research related to SEA EAGLE to include but not be limited to collection of blood, tissue, egg and water samples for analysis of the effects of an array of contaminants and heavy metals on contamination in eagles from various locations. This research will build upon ongoing and previous research on the effects of contaminants on eagle health, productivity, and population dynamics and on the use of eagles as biosentinels of ecosystem health in aquatic systems. 2. To support laboratory analysis of contaminant concentrations in samples of blood, tissues, eggs and water collected in association with SEA EAGLE. These analyses will include but not be limited to comparisons of contaminants and heavy metals among species, locations, and across time (i.e., compared with historical data). 3. The data collected and developed in objectives 1 and 2 will contribute to agency-focused reports, presentations at scientific meetings (particularly by students), and briefings of appropriate agency personnel on the findings (i.e., dissemination of material directly to agencies and wildlife managers). Due to the international nature of the research outlined in 1 and 2 above, travels to regional, national, and international scientific meetings will be prioritized to increase dissemination of the results. 4. The graduate student, with assistance from the PIs, will develop and submit one or more manuscripts from this work to appropriate peer-reviewed, scientific journals.	None

Enhancement of suppressed bald cypress (Taxodium distichum) growth on the Roanoke River NWR, NC	December 2011	The purpose of this project is to reduce the canopy cover of water tupelo around the pockets of suppressed baldcypress trees in an effort to provide the necessary light and space to allow the trees to reach canopy height. The specific objective of this project is to assess impacts of canopy opening on growth dynamics of tagged and banded bald cypress trees to develop and improve habitat restoration techniques. It is hypothesized that increased sunlight (reduced competition) will enhance growth of the released bald cypress. Task 1 Tupelo trees that are shading young cypress trees will be identified and injected with the herbicide Habitat. Task 2 Growth of the target cypress trees will be monitored using growth bands placed around the tree at breast height designed to expand with the tree.	None
Movement Patterns and Habitat Use of Migratory Canada Geese Wintering In and Adjacent to the Santee National Wildlife Refuge Phase #2.	December 2010	The goal of the proposed research is to examine the wintering ecology and to provide conservation insight for this subpopulation that historically uses wintering habitat on several NWRs in the Savannah-Santee-Pee Dee ecosystem. The objectives of the proposed research are to: (1) Determine the wintering distribution of migratory Canada Geese. The study will conduct in the Santee NWR. The Refuge is within the upper coastal plain region, in Clarendon County, South Carolina. A primary objective of the refuge is to provide winter habitat and protection of waterfowl. Significant waterfowl concentrations winter on and around the Refuge. Prior to the arrival of migratory geese I the fall, resident goose distribution will be determined through a series of aerial surveys. Distribution, movement patterns, and home range sizes of wintering migratory Canada geese will then be measured through conventional telemetry techniques and through observations of birds with neck collars. The distribution of resident geese and the degree of mixing with migratory geese also will be determined through the use of conventional telemetry and neck collars. Lastly, local land use planning data from conventional telemetry will be analyzed using GIS mapping to determine potential habitat loss impacts.	None
PFAS Bioaccumulation in Coastal Seabirds	December 2024	Per-and polyfluoroalkyl substances (PFAS) are anthropogenic pollutants that are ubiquitous in human and natural environments, highly persistent, and associated with impacts at low levels of exposure in humans. PFAS are released into the environment via a number of pathways, including use and disposal of consumer products, manufacturing activities, and application of aqueous film forming foams (AFFF), particularly at DoD sites. , Limited information exists relating concentrations of multiple precursors or terminal PFAS in abiotic matrices impacted by AFFF (e.g. sediment, water) and prey items (e.g. fish, invertebrates) to observed residue levels in avifauna or other predators at or near AFFF-impacted sites. The poor understanding of these pathways and relationships is problematic considering avifauna, including seabirds, have been documented to contain elevated levels of PFOS and other PFAS, with limited data suggesting potential impacts on hormone disruption, lipid expression, and reproduction at current exposure levels. The project is a collaboration of researchers across multiple organizatios and includes The Universitty of Rhode Island, The Nature Conservancy, and SC DNR. We will measure the bioaccumulation and biomagnification of a wide range of PFAS in seabirds that rely on environments and food webs downstream from Joint Base Charleston within the Charleston, SC region, using a unique combination of a field sampling campaign paired with biologging efforts, coupled to analysis of targeted terminal PFAS, environmental precursors, EOF, and stable isotopes. This comprehensive field effort will leverage collaborative partnerships to sample environmental media (air, water, sediment) and prey food, and will be paired with spatial tracking efforts and biological sampling of adult seabirds, chicks, and eggs, to provide novel information about the bioaccumulation of PFAS in estuarine and marine avifauna.

Using flow-ecology relationships to inform the state water planning in South Carolina	July 2024	Appropriation of water resources will continually increase with the rapidly growing human population in South Carolina, increasing 11.3% from 2010 to 2019. Protecting instream flows for ecosystem services will be one of society’s great challenges this century. South Carolina is a water-rich state that will face unique challenges and opportunities as demand increases. Protecting instream flow from anthropogenic alterations and maintaining ecosystem services of water resources first requires an understanding of the relationship between aquatic organisms and instream flow. Accordingly, the goal of the proposed project is to identify key relationships between flow metrics and biotic response (flow-ecology relationships) in the State’s eight, major river basins and to use these relationships to predict the response of aquatic organisms to changes in streamflow and water withdrawals to inform river basin planning across the State.

An Atlas and Registry for Seabird Colonies and Associated Habitats in the Northern Gulf of Mexico	March 2024	Along with key stakeholders from federal agencies, state agencies, and NGOs in the northern Gulf of Mexico, the SC Cooperative Research Unit is developing an Atlas and Register of Seabird Colony Sites for the region. The PIs met with stakeholders in summer 2022 to begin the process of obtaining colony data and focusing the atlas effort.	The coastal zone of the northern Gulf also supports a diverse array of breeding nearshore seabirds most of which are colonial and nest on islands, marshes, mainland beaches, or human-made structures. Although nest-site fidelity is common among seabirds, the dynamic nature of the coastal zone in the northern Gulf can result in inter-annual shifts in the locations of colonies and in the existence, size, or stability of the islands or habitats that support them. Overlaid on this dynamic system is a stakeholder network responsible for management of these species and their breeding habitats that includes natural resource agencies from five states, multiple federal agencies (e.g., USFWS, NPS, BLM, DOD, ACOE), and numerous private organizations (e.g., National Audubon Society, Nature Conservancy). In an effort to coordinate and facilitate the management and conservation of avian taxa throughout this wide range of habitats and across this complex network of stakeholders in the northern Gulf, the Gulf of Mexico Avian Monitoring Network (GoMAMN) recently released strategic monitoring guidelines that highlighted the need for a spatial inventory of breeding sites of seabirds in the region. The development of this Atlas will build from efforts by the Gulf Coast Joint Venture’s Bird Nesting Island Cooperative, and it’s “Atlas” Team. Stakeholders from each Gulf state and from regional NGOs will also be participating. The Atlas will support inventory, monitoring, management, disaster response, and research. The atlas and register also will be valuable for marine spatial planning issues, including but not limited to sighting wind turbines, scheduling and siting sand-dredging and beach nourishment operations, managing recreation and access, and land/marine conservation planning.
Edisto River Flow Effects on Summertime Water Temperatures: Are Thermal Tolerances of SWAP Fishes Exceeded at Low Flows?	December 2027	The Edisto River has the highest number of water withdrawal registrations and the highest maximum monthly withdrawals of any river basin in the state of South Carolina (SCDHEC 2020). Reduced flows may negatively impact SWAP listed fish species through a variety of mechanisms, but elevated water temperatures during low flow events could be especially detrimental to SWAP species such as Striped Bass <i>Morone saxatilis</i> that require coolwater habitat. The genetically unique Striped Bass population endemic to the ACE basin seeks thermal refuge in the upper portions of the basin (e.g., North and South Fork Edisto River) during summer. For such species, decreased flow during summer may cause water temperatures to exceed thermal tolerances as has been observed for other coolwater riverine species. Key knowledge gaps limit our ability to understand how increases in summertime flow-dependent temperature may negatively impact species of greatest conservation need in the Edisto River Basin. First, there is no knowledge of the relationship between flow, summer air temperature, and water temperature. Developing a statistical relationship between these variables would be a first step towards assessing the thermal impacts of low flow during summer. Second, for many SWAP species, such as Bannerfin Shiner <i>Cyprinella leedsi</i>, there is no published data on thermal tolerance meaning that even if a relationship between flow and summertime water temperature were developed, we would be unable to understand the biological implications. These knowledge gaps are especially relevant given the large, predicted increases in water demand in the Edisto Basin and projected changes in temperature and precipitation due to climate change over the next several decades.This project will provide critical information necessary for protecting SWAP listed freshwater and diadromous fish species in the Edisto River Basin. Specifically, this project will determine maximum thermal tolerances for two SWAP freshwater fish species in the Edisto River Basin (Bannerfin Shiner [high priority], Edisto River Stiped Bass [moderate priority]) and create detailed maps of available thermal habitat under a range of current and projected, future flow scenarios for the two SWAP fish species listed above as well as the Shortnose Sturgeon [listed under ESA as endangered throughout its range]).

Assessing Nesting Status of Black-capped Petrels Following Acute Disturbance Events	December 2023	The Black-capped Petrel <i>Pterodroma hasitata</i> (known regionally as Diablotin) is a medium-size gadfly petrel endemic to the Caribbean. The species has a declining population and is considered Endangered throughout its range. The species is currently proposed by FWS as Threatened under the US Endangered Species Act. Population estimates based on at-sea observations range from 2,000 to 4,000 individuals, with a fragmented breeding population estimated at 500 to 1,000 pairs. Currently, the only confirmed breeding areas are located on the island of Hispaniola. The U.S. Fish and Wildlife Service (2018) predicted that the two major breeding areas on Hispaniola are likely to face extirpation by 2070 and, if no additional nest sites are found, this would represent a potential loss of up to 85-95% of the currently known breeding population. We will assess the nesting status of Black-capped Petrels following acute predation and fire events, and evaluate the deployment of artificial burrows as a recovery technique. Such an assessment of resiliency is consistent with objectives of the 2018 SSA developed for the species.	The Black-capped Petrel <i>Pterodroma hasitata</i> is a medium-size gadfly petrel endemic to the Caribbean. The species has a declining population and is considered Endangered throughout its range. The species is currently proposed by FWS as Threatened under the US Endangered Species Act. Currently, the only confirmed breeding areas are located on the island of Hispaniola with <100 nests discovered. We will be partnering with the non-profit Grupo Jaragua (GJ), which leads the conservation efforts for the Black-capped Petrel in the Dominican Republic. GJ coordinates conservation actions for the species, including capacity building, nest searches, colony monitoring and predator control. The project will determine if breeding Black-capped Petrels are resilient to catastrophic threat events that destroy or degrade nests/nesting habitat and kill birds, and will evaluate the use and efficacy of artificial burrows as a practical and beneficial conservation intervention. Such an assessment of resiliency is consistent with objectives of the 2018 SSA developed for the species.<br><i> </i>
Research on Data Integration	December 2022	I am exploring several developments related to data integration approaches including combining multiple data sources (e.g., autonomous recording units and point count data or aerial and ground count data) and power analyses for integrated population models.	Combining multiple sources of data is a new area of research. The development of new models allows for the integration of data sources from different data streams to better inform management and conservation. I am partnering with South Carolina Dept. of Natural Resources, Environment and Climate Change Canada, and USDA NRCS on various projects related to data integration. The research will inform potential conservation efforts related to a wide variety of vertebrate species.
Effects of forest management on early-successional avian species in South Carolina	May 2021	We will assess the response of Ruffed Grouse, Golden-Winged Warblers, and other early-successional forest species to habitat management in the upstate of South Carolina.	South Carolina contains the southern-most extent for several early-successional avian species in the Appalachian Region, yet it is often not included when monitoring or surveying for these species. As several of these species are in decline, more information is needed to determine how they are using habitats in the southern portion of the range as well as a more information on their occupancy rates across suitable habitats. This project is in collaboration with South Carolina Department of Natural Resources. Information from the study will help to inform management practices and conservation needs of species in the state as well as general ecological information about habitat use of these avian species at the edge of their range.
Response of Bachman's Sparrow to habitat management	December 2021	We are conducting research to determine how Bachman's Sparrow respond to habitat management such as fire and thinning in a wiregrass-free ecosystem.	Bachman's Sparrow is a species of conservation concern that typically inhabits open forest systems with wiregrass; however, little is known about how the species responds to wiregrass-free ecosystems like those in South Carolina. Our research will focus on quantifying abundance, nest success, and survival of Bachman's Sparrow in these special ecosystems to provide insights into management of wiregrass-free habitats for managers. This project is in collaboration with South Carolina Department of Natural Resources. The results will help managers understand optimal burn frequencies and vegetation needs for Bachman's Sparrow and also provide additional information about the ecology of the species.
Monitoring of rock gnome lichen populations	May 2021	We are working to develop a monitoring protocol to provide a status and assessment tool for rock gnome lichen.	Rock gnome lichen is an endangered species of lichen currently occupying the Southern Appalachians. Population monitoring for the species has occurred twice previously, but a consistent survey methodology is needed to monitor populations for 5-year status updates and potential delisting of the species in the future. We are working with U.S. Fish and Wildlife Service to develop a monitoring protocol to provide a status and assessment tool for rock gnome lichen. Our survey design will be implemented for future population monitoring efforts as well as inform ecology of the species related to the effects of Hemlock Woolly Adelgid on rock gnome lichen populations through vegetation changes.
Variation of Chronology of Wild Turkey Gobbling in the Upstate of South Carolina	December 2021	We are researching the chronology of wild turkey gobbling in the upstate of South Carolina using point counts and autonomous recording units. We are comparing gobbling chronology in the upstate to other locations as well as looking at variation in gobbling related to date, hunting pressure, and elevation.	Wild Turkeys are an important game species but potentially declining in the Southeast. Information about the timing of harvest relative to their breeding season is needed to better determine the effects of harvest on survival and reproduction. We are comparing gobbling chronology in the upstate to other locations as well as looking at variation in gobbling related to date, hunting pressure, and elevation to better inform management decisions about harvest seasons and ecology of Wild Turkeys in Upstate South Carolina. This project is in collaboration with South Carolina Department of Natural Resources. Our research will inform management decisions related to harvest of turkeys in this region relative to other regions in South Carolina.
Tracking Atlantic and Caribbean Seabirds	December 2023	The Caribbean and Bahamas support ~ 25 species of breeding seabirds. Despite the regions importance to seabird conservation and diversity, seabirds there have been very understudied particularly with respect to migratory connectivity throughout the Atlantic. Our goal has been to steadily increase baseline data on the spatial ecology of seabirds in the region by partnering with local NGOs to build local capacity.<br><br>To date, we have collected tracking data from several species of pelagic seabirds in Mexico, Jamaica, the Dominican Republic, The Bahamas, British Virgin Islands, St Eustatius and Tobago in collaboration with federal agencies, and local Universities and NGOs. One particular focus of our research in the region has been to expand research and baseline data on the endangered Black-capped Petrel. The species is endemic to the region, nesting at only a few sites on Hispaniola. Considered globally endangered, the species is under review for listing by the US FWS. We are conducting research on movement ecology, diet, and reproductive ecology with local partners and to date have conducted the only tracking efforts for this species.	Many species of seabirds breeding in the Caribbean occupy waters off the Atlantic and Gulf coasts of the US during some portion of the annual cycle. As marine spatial planning becomes a pressing issue in the region, data are needed to enhance our understanding of the seabird community in the South Atlantic Bight and the Gulf of Mexico. Although current ship-based and aerial surveys are the standard methods used to measure abundance and distribution of birds at sea, each is a population-based survey that provides information without regard to individual variability or colony of origin. We are deploying tracking devices to measure movement patterns of seabirds in the Caribbean, Gulf of Mexico, and western north Atlantic. We are collaborating with the US FWS and also with local NGOs and Universities throughout the Caribbean. Data from individual tracking efforts will allow us to assess variability in movements and use patterns, fidelity to specific marine locations, and the relationship between marine use areas and breeding locations and population trends at the breeding grounds.
Assessment of temperate-breeding Canada goose management in Kansas	December 2020	Resident Canada geese are a wildlife management success story, but are exceeding societal thresholds of tolerance in many areas. Management strategies are needed to address this conflict. Accurate counts and determining effect of management strategies are important in resolving conflicts with resident Canada goose. Translocation is a potential management strategy for over abundant geese. This research is a collaborative effort among the Kansas Cooperative Fish and Wildlife Research Unit, South Carolina Cooperative Fish and Wildlife Research Unit, and Kansas Wildlife, Parks, and Tourism. Survey methodology is being assess to improve precision of resulting estimates. Translocation does reduce survival of resident Canada geese.	<b>Problem statement:</b><br>Resident Canada geese are a wildlife management success story, but are exceeding societal thresholds of tolerance in many areas.

Gulf of Mexico Marine Assessment Program for Protected Species	December 2022	Limited information is available regarding the species composition, distribution, and abundance of seabirds using the nearshore and offshore waters of the Gulf of Mexico. For example, to date there have been only three standardized and/or repeatable surveys for pelagic seabirds in the Gulf. The sparse data available on distribution and abundance of seabirds in the Gulf hinders both our understanding of seabird ecology and our ability to plan for or respond to data needs during oil and gas activities. Our goal is to conduct vessel-based surveys for pelagic seabirds in the northern Gulf. The research will satisfy a portion of the newly initiated Gulf of Mexico Marine Assessment Program for Protected Species (GoMMAPS). The study area includes the northern portion of the Gulf of Mexico Basin which represents the approximate location of the EEZ of the USA. This region encompasses the Western, Central, and Eastern Planning Areas of the Bureau of Ocean Energy Management. Vessel-based surveys will occur throughout each planning area. Beginning in 2017, we conducted surveys using NOAA vessels to assess the abundance and distribution of birds utilizing the pelagic environment. We are also developing additional components that will use telemetry to document movement patterns of seabirds from both the nearshore and pelagic environments. Collectively, these data will permit spatially-explicit modeling of seabird abundance and distribution across the Gulf and provide a critical basis for understanding and addressing potential impacting factors in the region.	Seabirds are one of the most threatened groups of birds globally yet understudied in many regions of the US. For example, limited information is available regarding the species composition, distribution, and abundance of seabirds using the nearshore and offshore waters of the Gulf of Mexico. This region also supports some of the highest densities of oil and gas development in marine ecosystems in the world. The sparse data available on distribution and abundance of seabirds in the Gulf combined with the extent of oil and gas activity hinders both our understanding of seabird ecology and our ability to plan for or respond to data needs during oil and gas activities. Our goal is to conduct vessel-based surveys for pelagic seabirds in the northern Gulf. Collaborators include the Bureau of Ocean Energy Management, US Fish & Wildlife Service, USGS Patuxent Science Center, USGS Wetlands and Aquatic Research Center, National Oceanographic and Atmospheric Administration, Michigan State University, and private partners. We will combine seabird data with similar data collected on marine mammals and sea turtles and, collectively, these data will permit spatially-explicit modeling of abundance and distribution of marine vertebrates across the Gulf. Models will provide stakeholders with tools to predict occurrence and potential impacts with respect to marine spatial planning and future spills.
Analysis of bird population count data	December 2018	Sea ducks are understudied relative to other species of waterfowl, especially in the southern portion of the US Atlantic Coast. Climate change and human activity (e.g., wind energy development) could impact their wintering sites causing negative carry-over effects through the rest of their life cycle. Our goal was to better describe wintering sites, movement, and habitat use of black scoters along the southern US Atlantic Coast using satellite telemetry and aerial survey data. This project was a collaboration between USFWS, Environment Canada, and USGS. The output from this study could be used to better inform survey methods for black scoters or to decrease conflict with wind energy development in the area.

Monitoring success of Farm Bill programs in conserving avian wildlife	December 2018	The purpose of this study is to evaluate a new tool to monitor the effectiveness of, and inform Farm Bill incentive programs related to avian species of conservation concern. In this project we will first demonstrate the utility of new remote acoustic detecting technology to monitor avian community<br>responses to EQIP enrollment on private lands in SC. Findings will not only provide guidance on improved monitoring effectiveness of incentive programs, but provide unique insights into how such technology can be used to identify areas of future focus. Second, we will evaluate the transferability of this technology. To that end, we will provide several trainings and a technical manual on how managers, field personnel, and landowners can use acoustic monitoring devices to monitor for avian species. We are collaborating with USDA NRCS and SC DNR for this project.

Spatial Ecology of Brown Pelicans in the South Atlantic Bight	December 2023	As a nearshore marine predator and species of conservation concern, Brown Pelicans (Pelecanus oddicentalis) in the southeastern United States constitute a valuable study population for investigating coastal ecological systems. Despite occupying a highly visible and elevated trophic position in estuarine and oceanic ecosystems, movement parameters describing habitat use patterns, foraging behaviors, and migratory corridors are undeveloped at multiple spatial and temporal scales. This study aims to address these information gaps by outfitting breeding adult pelicans with high-resolution GPS satellite transmitters, which will provide accurate locational data throughout the annual life-history cycle. We will use these data to (1) examine movement and behavior of individual pelicans during the passage of hurricanes, (2) evaluate the risk exposure of pelican colonies to ship-based oil spills within Charleston Harbor, SC, using modeling products developed by NOAA, (3) assess the usage of discarded bycatch from shrimp trawlers by adult pelicans in relation to reproductive output by pairing movement data with diet samples, stable isotope analysis, and chick corticosterone concentrations, and (4) investigate the drivers of partial migration in brown pelicans and subsequently model shifts in both migration probability and non-breeding range of brown pelicans under multiple climate change scenarios.	Brown Pelicans have been understudied in the southeastern US and the sparse availability of data for pelicans (as well as other nearshore seabirds in the region such as Royal Tern, Sandwich Tern, and Black Skimmer) has resulted in a relatively incomplete picture of pelican ecology in a baseline environment. As such our understanding of habitat use at sea, population trends, and reproductive success for pelicans is very limited. Furthermore, the potential for an overlap between use areas of Brown Pelicans in the marine environment and proposed or existing offshore energy activities may be substantial in the region. We are collaborating with state agencies (SC, GA, FL), BOEM, and the USGS Outer Continental Shelf Program to study spatial and reproductive ecology of pelicans in the region. Data will be used to generate distribution maps and movement models showcasing breeding ranges, migratory pathways, wintering locations, and site fidelity. This information will greatly expand our knowledge of this charismatic species in the Atlantic, and complement prior research recently conducted on Brown Pelicans in the Gulf of Mexico.
Use of Horseshoe Crab Eggs by Migratory Shorebirds	December 2016	The goal of the research is to enhance our understanding of the relationships between migratory shorebirds, particularly Red Knots, and spawning horseshoe crabs. Our objectives are to survey horseshoe crabs at key sites in South Carolina from March – June of 2015 and 2016.	American Horseshoe Crab (Limulus polyphemus) eggs provide migratory shorebirds with an abundant food source at stopover sites, allowing the birds to rapidly gain weight for their long migration to arctic breeding grounds. Shorebird utilization of Horseshoe Crab eggs has been well documented at northeastern stopover sites such as the Delaware Bay. However this relationship has not been well studied in the southeast, specifically in South Carolina. The purpose of this study is to determine if there is a correlation between density of Horseshoe Crab eggs and abundance of foraging shorebirds during spring migration at Cape Romain National Wildlife Refuge.<br>To accomplish this, we monitored 10-12 study plots between March and June 2015-2016 at predicted Horseshoe Crab spawning sites throughout the refuge. We conducted weekly shorebird surveys and sampled plots twice a month for densities of Horseshoe Crab eggs. Across both years, we collected 1,081 Horseshoe Crab egg samples and conducted 325 shorebird surveys. Additionally, we coordinated refuge-wide Horseshoe Crab spawning surveys on the evenings of 2 June 2015, and 22-24 May 2016. We used a linear regression to compare the density of eggs in each plot with the number of foraging shorebirds. Our results show a positive correlation between foraging shorebirds and Horseshoe Crab eggs for both years.<br>Additional analyses will further explore this relationship by conducting a dietary analysis of shorebird fecal samples. We will also investigate the relationship between sand grain size and the presence of shorebirds and Horseshoe Crab eggs across our study site beaches. The results of our study will help to provide a better understanding of Cape Romain NWR as a stopover site for shorebirds and enable us to compare densities of Horseshoe Crab eggs and spawning adults with other stopover sites along the Atlantic coast.

Can spatial food web subsidies associated with river hydrology and lateral connectivity be detected using stable isotopes? Food Webs. 2023. \| Abstract	March 2023	Hydrology, lateral connectivity and stable isotope ratios of fishes and mussels in the Guadalupe River, Texas, were analyzed for evidence of spatial food web subsidies between the active channel and oxbow lakes in the floodplain. During and following lateral connections, aquatic organisms residing in the channel may assimilate material from sources imported from oxbows, and oxbow residents may consume and assimilate material imported from the channel. During surveys conducted between March 2016 and April 2017, fish, mussel, algae, and riparian plants samples were collected in and around two oxbows and adjacent channel sites for analysis of stable isotope ratios. Biplots of d<sup>13</sup>C and d<sup>15</sup>N were graphed for basal sources and specimens of Longnose Gar <i>Lepisosteus osseus, </i>Gizzard Shad <i>Dorosoma cepedianium, </i>Threadfin Shad <i>Dorosoma petenense, </i>Bullhead Minnow <i>Pimephales vigilax, </i>Smallmouth Buffalo <i>Ictiobus bubalus, </i>White Crappie <i>Pomoxis annularis</i>, sunfishes (<i>Lepomis</i> species combined), and two mussel species (combined) captured from oxbows and the channel. Within each graph, a source polygon was drawn to indicate the space occupied by animals that could have assimilated feasible combinations of source materials from the oxbows or river channel. Based on positions of animals within source polygons, riparian plants were the most important source of organic matter supporting biomass of fishes and mussels both within the channel and oxbows during every survey period, with algae contributing minor percentages. Most organisms had isotopic signatures consistent with assimilation of <i>in situ</i> sources, or else were inconclusive with regard to cross-habitat exchanges. Between-habitat food web subsidies were indicated for 7.6% of 314 organisms from oxbows and 11.2% of 231 from the channel, and these cases followed high flow pulses that connected oxbows for extended periods. Several issues that compromise inferences from stable isotope analysis were identified, and attempts to estimate spatial food web subsidies in fluvial systems could be enhanced by analyzing additional biomarkers, such as isotopic ratios of other elements and compound-specific stable isotopes, as well as additional sources, time-specific biotracers, and experimental approaches that directly track movement of sources and organisms in spatially structured food webs.
Wilkinson, B.P., and P.G.R. Jodice. Support for the fasting endurance hypothesis of partial migration in Brown Pelicans. 2023. Ecosphere 2023;14:e4365. https://doi.org/10.1002/ecs2.4365 \| Abstract \| Download	February 2023	Partial migration occurs when only a certain fraction of a population or species migrates instead of all individuals. Considered an evolutionary precursor, understanding why some individuals choose to undertake migration while others do not may serve to inform general migratory theory. While several hypotheses currently exist for explaining the maintenance of partial migration, empirical support for many is limited. To address this gap, we analyzed telemetry data acquired from individual brown pelicans (<i>Pelecanus occidentalis</i>; <i>n</i> = 74), a partially migratory seabird, nesting on six colonies in the South Atlantic Bight over the course of four autumn migrations using a Cox’s proportional hazards model. We estimated that approximately 74% of pelicans nesting within the study area may be migratory on an annual basis, with the remainder staying within the surrounding marine ecoregion year-round. Mean date of migration initiation was 9 November, although movements occurred from September – December. Modeling results indicated significant effects of rising sea-surface temperatures and decreased body condition on migration rate. We suggest that the ontogenetic migration of the primary forage species of brown pelicans from estuarine to pelagic environments causes a seasonal reduction in prey, and that individuals in poor body condition are unable to meet the energetic demands potentially associated with this decrease in prey availability (i.e., the fasting endurance hypothesis of partial migration). Although we did not find evidence for a density-dependent migratory response, the effects of intraspecific competition on migration in pelicans appears to warrant consideration.

Stoczynski, L., Scott, M. C., Bower, L., & Peoples, B. Effects of environment and metacommunity delineation on multiple dimensions of stream fish beta diversity. Frontiers in Ecology and Evolution, 11, 182. \| Abstract	March 2023	In a metacommunity context, beta diversity is driven by the interplay between abiotic factors and dispersal as represented by spatial distance among communities. Most existing studies have considered only ‘natural’ abiotic factors and have ignored anthropogenic factors such as land cover change and pollution. Most studies have focused only on taxonomic beta diversity, and few have considered functional or phylogenetic beta diversity. Including anthropogenic factors and multiple dimensions of biodiversity may explain additional variation in beta diversity, providing new insight into how metacommunities are structured across the landscape. In this study, we used a 350 site stream fish abundance dataset from South Carolina, USA to quantify variation in beta diversity explainable by dispersal, as well as natural and anthropogenic abiotic variables. We investigated metacommunity drivers along three spatial delineations by breaking up the dataset into a metacommunity at the whole state level, two geomorphologically distinct metacommunities of the upstate and lowlands, and four natural watershed metacommunities. Within each of these metacommunities we calculated taxonomic, functional, and phylogenetic beta diversity and used variation partitioning to determine explained variation. We explained 25-81% of beta diversity for stream fish metacommunities. We observed differing importance of spatial, natural, or anthropogenic factors based on the spatial delineation and diversity dimension. We detected distinct structuring of stream fish communities in South Carolina occurring between the upstate and the lowlands. When accounting for the geomorphic differences the fall line creates, we observed a significant anthropogenic signal in the upstate and lowland metacommunities. Spatial, environmental, and anthropogenic factors explained slightly more variation in beta diversity for the taxonomic dimension compared to the functional and phylogenetic dimensions. Our study highlights the importance of including anthropogenic factors when trying to determine mechanisms for stream fish community structure and the significance of spatial delineation in how researchers interpret their results.

Landscape Ecology 37, 2607–2618. doi.org/10.1007/s10980-022-01487-9 \| Abstract \| Publisher Website	October 2022	<b>Context: </b>Anticipating where an invasive species could become abundant can help guide prevention and control efforts aimed at reducing invasion impacts. Information on potential abundance can be combined with information on the current status of an invasion to guide management towards currently uninvaded locations where the threat of invasion is high.<br><b>Objectives: </b>We aimed to support management by developing predictive maps of potential cover for cheatgrass (<i>Bromus tectorum</i>), a problematic invader that can transform plant communities. We integrated our predictions of potential abundance with mapped estimates of current cover to quantify invasion potential within lightly invaded areas.<br><b>Methods: </b>We used quantile regression to model cheatgrass abundance as a function of climate, weather, and disturbance, treating outputs as low to high invasion scenarios. We developed a species-specific set of covariates and validated model performance using spatially and temporally independent data.<br><b>Results: </b>Potential cheatgrass abundance was higher in areas that had burned, at low elevations, and when fall germination conditions were more favorable. Our results highlight the extensive areas across the Great Basin where cheatgrass abundance could increase to levels that can alter fire behavior and cause other ecological impacts.<br><b>Conclusions:</b> We predict potential cheatgrass abundance to quantify relative invasion risk. Our model results provide high and low scenarios of cheatgrass abundance to guide resource allocation and planning efforts across shrubland ecosystems of the Great Basin that remain relatively uninvaded. Combining information on an invasive species’ current and potential abundance can yield spatial predictions to guide resource allocation and management action.

Genetic and demographic consequences of range contraction patterns during biological annihilation. Scientific Reports 13, 1691. doi.org/10.1038/s41598-023-28927-z. \| Abstract	January 2023	Species range contractions both contribute to, and result from, biological annihilation, yet do not receive the same attention as extinctions. Range contractions can lead to marked impacts on populations but are usually characterized only by reduction in extent of range. For effective conservation, it is critical to recognize that not all range contractions are the same. We propose three distinct patterns of range contraction: shrinkage, amputation, and fragmentation. We tested the impact of these patterns on populations of a generalist species using forward-time simulations. All three patterns caused 86–88% reduction in population abundance and significantly increased average relatedness, with differing patterns in declines of nucleotide diversity relative to the contraction pattern. The fragmentation pattern resulted in the strongest effects on post-contraction genetic diversity and structure. Defining and quantifying range contraction patterns and their consequences for Earth’s biodiversity would provide useful and necessary information to combat biological annihilation.

Naro-Maciel E, Gaughran SJ, Putman NF, Amato G, Arengo F, Dutton PH, McFadden KW, Vintinner E, Sterling EJ. Journal of the Royal Society Interface \| Abstract \| Download	April 2014	Population connectivity and spatial distribution are fundamentally related to ecology, evolution, and behavior. Here we combined powerful genetic analysis with high quality simulations of particle dispersal in an ocean circulation model to investigate the distribution of green turtles foraging at the remote Palmyra Atoll National Wildlife Refuge, Central Pacific. We analyzed mitochondrial sequences from turtles (n = 349) collected there over five years (2008 - 2012). Genetic analysis assigned natal origins almost exclusively (~97%) to the West Central and South Central Pacific combined Regional Management Units. Further, our modeling results indicated that turtles could potentially drift to Palmyra Atoll via surface currents along a near-Equatorial swathe traversing the Pacific. Comparing findings from genetics and modeling highlighted the complex impacts of ocean currents and behavior on natal origins. Although the Palmyra feeding ground was highly differentiated genetically from others in the Indo-Pacific, there was no significant differentiation among years, sexes, or stage-classes at the Refuge. Understanding the population distribution of this foraging population advances knowledge of green turtles and contributes to effective conservation planning for this threatened species.

North American Journal of Fisheries Management 26:976-982. \| Abstract \| Publisher Website	December 2006	We assessed fish escapement from two South Carolina reservoirs, Par Pond and L Lake, from spring 2002 through summer 2003. Escapement was greatest in the spring and early summer, with lake chubsucker Erimyzon sucetta dominating the escapement catch in early spring and several sunfishes Lepomis spp. dominating in late spring and early summer. Most of the escaping centrarchids were bluegill L. macrochirus, warmouth L. gulosus, and redbreast sunfish L. auritus in L Lake and warmouths, bluegills, dollar sunfish L. marginatus, and spotted sunfish L. punctatus in Par Pond. Escapement was enhanced by high reservoir water levels and surface discharge over the spillway. Escapement declined during periods of hypolimnetic release from bottom discharge gates. Location of the Par Pond discharge structure in the littoral zone rather than the pelagic zone as in L Lake contributed to greater escapement of littoral species in Par Pond. Species composition in the escapement catches and reservoirs was not significantly correlated. Relatively low escapement from L Lake and Par Pond compared with that in other reservoirs may have been related to the configuration of the discharge structures, low water levels during 2002, fish habitat preferences, species composition and abundance in the reservoirs, and low rates of discharge.

Acta Chiroptologica 17:131-141. https://doi.org/10.3161/15081109ACC2015.17.1.011 \| Abstract	July 2015	Although several studies have described roost use by Rafinesque’s big-eared bats, few studies have examined roost selection. We examined roost use and selection by Rafinesque’s big-eared bat at the tree, stand, and landscape scales during the maternity season in pristine old-growth habitat in the Coastal Plain of South Carolina. We located 43 roosts (14 maternity, 29 solitary) through cavity searches and radio-telemetry. Maternity colonies and solitary individuals selected roosts based on similar characteristics. The best model explaining roost selection by all bats included tree and stand characteristics; landscape factors had little influence on roost use. Bats selected large diameter trees in areas with a high density of trees with cavities in the surrounding area. Most roosts (67.4%) were in water tupelo (Nyssa aquatica) in semi-permanently flooded and saturated areas. Half of maternity roost cavities had upper bole openings whereas only 25.8% of solitary roosts had upper bole openings. Bats that roosted with maternity groups stayed in roosts for significantly shorter periods of time (1.3 ± 0.1 days) and used significantly more roost trees (5.0 ± 0.6 roosts) than adult males (3.8 ± 1.10 days, 2.3 ± 0.4 roosts, respectively). Maternity colony use of cavities with upper bole openings and shorter residency times suggest that predator avoidance may have been an important factor governing roosting behavior of maternity colonies in this area. Our results suggest that retention of large diameter, hollow trees in wetland areas will benefit Rafinesque’s big-eared bat individuals and maternity colonies in this area.

Hidden in plain sight: integrated population models to resolve partially observable latent population structure. 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.

Springer Verlag. \| Abstract	December 2010	Abstract: The term ‘seabird’ is generally applied to avian species that forage in the marine environment over open water. Seabirds typically nest in colonies and are long-lived species with low annual reproductive rates. Seabird breeding sites typically occur on islands or along coasts and as such are often at the boundaries of ecological or political zones. During the breeding season, seabirds cross a very distinct terrestrial/marine ecological boundary on a regular basis to forage. Even relatively ‘local’ species cross multiple jurisdictions within a day (e.g., state lands and waters, and federal waters) while pelagic species may transit through international waters on a daily, weekly, or monthly time-frame. Seabird life-histories expose individuals and populations to environmental conditions affecting both terrestrial and marine habitats. The wide-ranging and transboundary nature of seabird ecology also exposes these species to various environmental and anthropogenic forces such as contamination, commercial fisheries and climate forcing that also are transboundary in nature. Therefore, wherever conservation of seabirds or the management of their populations is the goal, consideration must be given to ecosystem dynamics on land and at sea. Because the jurisdiction of agencies does not cross the land-sea boundary in the same manner as the seabirds they are managing, these efforts are facilitated by multi-agency communication and collaboration. By their very nature and by the nature of the systems that they must function within, seabirds embody the complexity of wildlife ecology and conservation in the 21st century.

Endangered Species Research 29:23-33. doi: 10.3354/esr00697 \| Abstract \| Download	November 2015	The Black-capped Petrel is an endangered seabird with fewer than 2,000 breeding pairs restricted to three confirmed breeding sites in Haiti and the Dominican Republic. To date, use areas at sea have been determined entirely from vessel-based surveys and opportunistic sightings and, as such, spatial and temporal gaps in our understanding of the species’ marine range are likely. To enhance our understanding of marine use areas we deployed satellite tags on three Black-capped Petrels breeding in the Sierra de Bahoruco National Park in the Dominican Republic along the border with Haiti, representing the first tracking study for this species and one of the first tracking studies for any breeding seabird in the Caribbean. During chick-rearing, petrels primarily used marine habitats in the southern Caribbean Sea, between the breeding site and the coasts of Venezuela and Colombia. Maximum distance from the breeding sites ranged from ca. 500 – 1500 km during the chick-rearing period. During the post-breeding period, each bird dispersed north and used waters west of the Gulf Stream offshore of the mid- and southern Atlantic coasts of the USA, as well Gulf Stream waters and deeper pelagic waters east of the Gulf Stream in the vicinity of the Blake Spur and Charleston Bump. Maximum distance from the breeding sites ranged from ca. 2000 – 2200 km among birds during the nonbreeding period. In total, petrels used waters located within 14 different exclusive economic zones suggesting that evolving management strategies for this species will be benefitted by continued international collaboration.

Endangered Species Research. https://doi.org/10.3354/esr001143. \| Abstract \| Download	September 2021	The black-capped petrel (<i>Pterodroma hasitata</i>) is an endangered seabird endemic to the western north Atlantic. Although estimated at ~1,000 breeding pairs, only ~100 nests have been located at two sites in Haiti and three sites in the Dominican Republic. At sea, the species primarily occupies waters of the western Gulf Stream in the Atlantic and the Caribbean Sea. Due to limited data, there is currently not a consensus on the geographic marine range of the species although no current proposed ranges include the Gulf of Mexico. Here, we report on observations of black-capped petrels during two vessel-based survey efforts throughout the northern Gulf of Mexico from 2010 - 2011 and from 2017 - 2019. During 558 days and ~54,700 km of surveys we tallied 40 black-capped petrels. Most observations occurred in the eastern Gulf, although birds were observed over much of the east-west and north-south footprint of the survey area. Predictive models indicated that habitat suitability for black-capped petrels was highest in areas associated with dynamic waters of the Loop Current. We used the Extent of Occurrence (EOO) and Area of Occupancy (AOO) concepts to delimit the geographic range of the species within the northern Gulf of Mexico. We suggest that the marine range for black-capped petrels be modified to include the northern Gulf of Mexico, recognizing that distribution may be more clumped in the eastern Gulf and that occurrence in the southern Gulf remains unknown due to a lack of surveys there. To date, however, it remains unclear which nesting areas are linked to the Gulf of Mexico.

Marine Biology 158:2289-2298. \| Abstract	July 2011	Shrimp trawling is common throughout the southeastern and Gulf of Mexico coasts of the USA and is the primary contributor to fisheries discards in these regions. Tens of thousands of nearshore seabirds nest near shrimp trawling grounds in the USA, but to date, there has been no assessment of the relationship between seabirds and shrimp trawlers. We examined the taxonomic composition of bycatch, rate at which seabirds scavenged bycatch, and energy density of discarded bycatch in a nearshore commercial shrimp fishery. Bycatch was primarily comprised of demersal fish that are not typically accessible to the plunge-diving and surface-feeding seabirds that occur in the area. Hence, seabird diets in the region appear to be broadened taxonomically by the availability of discards. Results from discard experiments indicated that 70% of the nearly 5,500 items discarded by hand were scavenged by seabirds and that the fate of a discarded item was most strongly predicted by its taxonomic order. Laughing gulls scavenged the greatest proportion of discards, although brown pelicans were the only species to scavenge more discards than predicted based upon their abundance. Because this is the first such study in the region, it is difficult to ascertain the extent or intensity of the impact that discards have on nearshore seabirds. Nonetheless, our results suggest that it will be difficult for managers to clearly understand fluctuations in local seabird population dynamics without first understanding the extent to which these species rely upon discards. This may be especially problematic in situations where seabird populations are recovering following natural or anthropogenic stressors.

Condor 116:588-598. \| Abstract	October 2014	Degradation of nesting habitat for coastal birds has led to the use of nontraditional nesting habitat. The American Oystercatcher is listed as a “Species of High Concern” by the U.S. Shorebird Conservation Plan and is declining in the southern portion of its US breeding range where ~50% of breeding oystercatchers nest on shell substrate instead of beachfront habitat. We measured daily survival rates during incubation and chick-rearing in shell rake habitats over five breeding seasons in the Cape Romain Region of South Carolina, USA. Of 354 nesting attempts monitored, 16.1% hatched at least one egg. The daily survival rate and probability of a nest succeeding during the incubation stage was 0.938 and 22.8%, respectively. Overwash and predation were the primary causes of nest loss. Of the 40 successful nests we monitored, 70.1% fledged at least one young. The daily survival rate of broods and probability of a brood succeeding for oystercatchers was 0.991 and 74.0%, respectively. Productivity in the Cape Romain Region is primarily being lost during the incubation phase when nests are exposed to overwash and predation. Mobile chicks may, however, be able to avoid flood events or predators by relocating to higher or more protected portions of a shell rake. It does not appear that the shell rakes being used for breeding in the Cape Romain Region are inferior compared to other habitats being used in other states. Our data suggest that conservation actions that target nest and chick loss from flooding and predation have the greatest opportunity to enhance reproductive success on these shell rakes, and that an assessment of the availability, structure, use, and protection status of shell rakes is warranted.

We examined 15,400 age-1 rainbow trout Oncorhynchus mykiss in a hatchery. Total length (mm), wet weight (g), and sex (sneaker male or unknown) were recorded for each fish. We also individually tagged each sneaker male with soft visual implant alphanumeric (VIalpha) tags that were sequentially numbered and held the fish for 25 d before inspection. Sneakers constituted 2.8% of the hatchery rainbow trout population and were smaller in total length and weight than typical rainbow trout of the same age. Retention of the VIalpha tags in sneakers was 58.9%, significantly lower than has been reported under similar circumstances. We found that sneaker males may contribute substantially to hatchery populations. Reduced tag retention in sneakers may bias studies evaluating the effect of hatchery fish on wild populations. We believe that hatchery-produced sneaker males have the potential to contribute importantly to the genetic composition of wild populations.

Evolutionary Ecology, 36(1), 93-116. https://doi.org/10.1007/s10682-021-10142-9 \| Abstract	January 2022	The influence of environment and phylogeny on morphological characteristics of organisms is well documented. However, little is known about how these factors influence scale shape in fishes, a feature which may be important for drag reduction. We evaluated the impact of both on scale shape variation in the primarily benthic, riverine darter clade (Percidae: Etheostomatinae) of fishes. We predicted that darters with close phylogenetic relationships and/or shared ecologies would have more similar scale shapes, but this relationship would be mediated by use of the substrate boundary layer. We used geometric morphometrics and seven homologous landmarks for 92 species of darters representing all genera and 37 terminal clades within genera to measure scale shape. Phylogenetic relationships and ecological categories describing habitat, spawning mode, and maximum body size of each species were summarized from the literature. We used ordinations to examine scale shape variation among phylogenetic and ecological groups. We conducted Phylogenetic Generalized Least Squares analyses to test for relationships between scale shape and ecological characteristics. Scale shape variation occurred within and among darter clades, and was significantly related to phylogeny. However, we found divergent scale shapes between close relatives and similar scale shapes between distantly related species. After accounting for phylogenetic signal, size and water column position were related to scale shape. Extra-large, hyperbenthic species had longer, narrower scales that may decrease laminar drag. Sub-benthic darters had scales that were narrower at the insertion, and with enlarged ctenial margins that may facilitate burying. Among benthic darters, size was significantly related to scale shape though a lack of clustering among many taxonomic and ecological groups may indicate that boundary layer use has reduced selective pressures from drag. Our results are consistent with others that have found both environment and phylogeny influence Teleost fish morphology.

Journal of Freshwater Ecology 19:411-417 \| Abstract	December 2004	Flathead catfish were introduced to the Altamaha River system, Georgia in the 1970’s. We determined the length-weight relationship, Von Bertalanffy growth parameters, and back calculated lengths by examining the sagittal otoliths of 331 individuals captured from this population. We found that there were no sex related differences in length weight relationship or Von Bertalanffy growth parameters. Flathead catfish in the Altamaha River system grow at about the same rate as individuals in other introduced populations.

Journal of Fish Biology 70:782-798. \| Abstract \| Publisher Website	December 2007	Spawning aggregations of five species of catostomids were observed on the two mid-channel gravel bars of the Savannah River, Georgia and South Carolina, in 2004 and 2005 to assess the degree of spatial and temporal overlap in the use of this habitat and determine the habitat preferences leading to segregation. Spawning catostomids showed a considerable amount of temporal overlap in their use of these mid-channel gravel bars. The observed temporal overlap was consistent between 2004 and 2005 and corresponded to temperatures at which species were present. The distribution of catostomids was not uniform at the upstream gravel bar. Carpsuckers Carpiodes sp., spotted sucker Minytrema melanops and robust redhorse Moxostoma robustum both demonstrated some spatial overlap with notchlip redhorse Moxostoma collapsum; however, their overall distributions were different from one another. Northern hogsucker Hypentelium nigricans was present across the gravel bars, apparently as an egg predator. Spawning catostomids segregated based on flow, depth, slope and substratum size. Whether due to limited habitat availability or changes in the timing of reproduction due to altered cues, temporal and spatial overlap occurs between spawning catostomids despite the apparent partitioning of available spawning habitat. It is unclear, however, if this overlap results in excessive mortality in the early life-history stages of these species. Results suggest spatial overlap among catostomid species was minimized due to species spawning in areas within a narrow range of conditions. Intraspecific interactions such as nest site superimposition or disturbance may be a concern.

Transactions of the American Fisheries Society 135:1145-1155. \| Abstract \| Publisher Website	December 2006	The robust redhorse Moxostoma robustum is a large riverine catostomid whose distribution is restricted to three Atlantic Slope drainages. Once presumed extinct, this species was rediscovered in 1991. Despite being the focus of conservation and recovery efforts, the robust redhorse's movements and habitat use are virtually unknown. We surgically implanted pulse-coded radio transmitters into 17 wild adults (460–690 mm total length) below the downstream-most dam on the Savannah River and into 2 fish above this dam. Individuals were located every 2 weeks from June 2002 to September 2003 and monthly thereafter to May 2005. Additionally, we located 5–10 individuals every 2 h over a 48-h period during each season. Study fish moved at least 24.7 ± 8.4 river kilometers (rkm; mean ± SE) per season. This movement was generally downstream except during spring. Some individuals moved downstream by as much as 195 rkm from their release sites. Seasonal migrations were correlated to seasonal changes in water temperature. Robust redhorses initiated spring upstream migrations when water temperature reached approximately 12°C. Our diel tracking suggests that robust redhorses occupy small reaches of river (˜1.0 rkm) and are mainly active diurnally. Robust redhorses were consistently found in association with woody debris and gravel streambed sediments along the outer edge of river bends. Fish exhibited a high degree of fidelity to both overwintering and spawning areas. Our observations of long-distance seasonal migrations suggest that successful robust redhorse conservation efforts may require an ecosystem management approach.

North American Journal of Aquaculture 67:89-92 \| Abstract \| Publisher Website	December 2005	We investigated the potential of prepositioned grid electrofishers as a means of collecting broodstock for the rare robust redhorse Moxostoma robustum. We found that combined with visual observation, this technique allowed for the efficient capture of fish in breeding condition. We were able to harvest eggs in the field and bring only fertilized eggs into the hatchery. There was no need to induce spawning hormonally. Although their use is limited by water depth and clarity, prepositioned grid electrofishers used in conjunction with visual observation warrants further consideration as an effective tool for the collection of reproductively active broodstock for conservation purposes.
Grabowski T.B., and J.J. Isely. 2007. Effects of flow fluctuations on riverine fish spawning habitat. Southeastern Naturalist 6:471-478. \| Abstract \| Publisher Website	July 2007	Shallow-water, lithophilic spawning fishes are among the most vulnerable to anthropogenic fluctuations in water levels. We monitored water levels and environmental conditions at the nest sites of Moxostoma robustum (Robust Red-horse) on a main-channel gravel bar in the Savannah River, GA–SC. During the course of the 2005 spawning season, over 50% of the observed nest sites were either completely dewatered or left in near zero-flow conditions for several days. This occurred on two separate occasions, once early during the spawning season and then again near its conclusion. We hypothesize the habitat preferences of spawning Robust Redhorse leave them vulnerable to water-level fluctuations, and this phenomenon may be widespread in regulated river systems.

Ecology of Freshwater Fish 17:318-327. \| Abstract \| Publisher Website	June 2008	We collected scales to determine age and growth of four catostomid species (northern hogsucker Hypentelium nigricans, spotted sucker Minytrema melanops, notchlip redhorse Moxostoma collapsum, robust redhorse Moxostoma robustum) from the Savannah River, Georgia-South Carolina in spring 2004 and 2005. Robust redhorse was the largest species; reaching sexual maturity at an older age and growing faster as a juvenile than the other species. Spotted sucker did not achieve the same size as robust redhorse, but reached sexual maturity at younger ages. Notchlip redhorse was intermediate between the abovementioned two species in age at maturity and size. Northern hogsucker was the smallest species of the assemblage and reached sexual maturity at age 3. Both robust redhorse and spotted sucker were sexually dimorphic in size-at-age. The range of life history strategies employed by Savannah River catostomids encompasses the range of life history strategies exhibited within the family as a whole.

Southeastern Naturalist 7:475-482. \| Abstract \| Publisher Website	July 2008	.— Little is known about the behavior of individual fish in a spawning aggregation, specifically how long an individual remains in an aggregation. We monitored robust redhorse Moxostoma robustum (Cope) in a Savannah River spawning aggregation during spring 2004 and 2005 to provide an estimate of the total number of adults and the number of males comprising the aggregation and to determine male residence time and movements within a spawning aggregation. Robust redhorse were captured using prepostioned grid electrofishers, identified to sex, weighed, measured and implanted with a passive integrated transponder. Spawning aggregation size was estimated using a multiple census mark and recapture procedure. The spawning aggregation seemed to consist of approximately the same number of individuals (82-85) and males (50-56) during both years of this study. Individual males were present for a mean of 3.6 ± 0.24 days (± SE) during the 12-day spawning period. The mean distance between successive recaptures of individual males was 15.9 ± 1.29 m (± SE). We conclude that males establish spawning territories on a daily basis and are present within the spawning aggregation for at least 3-4 days. The relatively short duration of the aggregation may be the result of an extremely small population of adults. However, the behavior of individuals has the potential to influence population estimates made while fish are aggregated for spawning.

Our primary objective was to establish baseline data for hematological, biochemical, and serological values of a free-living population of pelicans during early chick development. We also evaluated the relationship among health variables and colony site, ectoparasite infestation, sex, and body condition index. Reference intervals are presented for health variables, including novel analytes for the species, and we present comparisons of our results with previously published values for wild pelicans. No significant relationships were found between health variables and nestling sex or body condition, however differences between colony sites and presence of ectoparasites were detected. The collection of baseline data and inclusion of health assessments as a regular component of management programs for seabirds can provide insight into the condition of species of conservation concern and enhance understanding of the ecological and demographic mechanisms regulating populations.

Predictability of flow metrics calculated using a distributed hydrologic model across ecoregions and stream classes: Implications for developing flow–ecology relationships. Ecohydrology, 15(2), e2387. \| Abstract	March 2022	Developing environmental flow standards requires an empirical understanding of the relationship between species’ ecology and instream flow. However, when congruent biological and hydrologic data are lacking, the accurate simulation of hydrologic metrics (HMs) corresponding to the locations of biological data is needed. Methods to predict HMs vary in formulation (i.e., statistical vs. process-based hydrologic models), ability to simulate HMs across the full range of the hydrologic regime (i.e., magnitude, duration, frequency, rate of change, and timing), and ability to transfer HMs from gaged to ungaged locations. Yet despite the breadth of modeling approaches, less attention has been paid to the variability in HMs associated with each approach. In this study, we apply a distributed hydrologic model to the diverse watersheds of South Carolina to examine the predictability of HMs from simulated daily time series of streamflow across ecoregions, stream classifications, and level of human alteration. In doing so, we contextualize the predictability of HMs, giving managers and researchers in South Carolina the flexibility of choosing HMs that are best suited for quantifying flow-ecology relationships based on the location, flow regime components of interest, and uncertainty of HMs. We found that at least one HM within each of the five flow regime components (out of a selected subset of 41 non-redundant HMs) was consistently and accurately predicted across the diverse streams of the study area. We discuss the patterns of predictability related to site characterizations and individual HMs and their implications for developing environmental flow standards.

Circulating fat-soluble vitamin concentrations and nutrient composition of aquatic prey eaten by American Oystercatchers in the southeastern United States. Submitted Journal of Avian Medicine and Surgery 28:216-224 \| Abstract	April 2014	The American oystercatcher is currently listed as a species of high concern by the United States Shorebird Conservation Plan. Adequate management of a wildlife population requires intimate knowledge of a species’ diet and nutritional requirements as nutritional status directly impacts overall health and reproduction of individuals and populations. Fat soluble vitamin concentrations of plasma obtained from American oystercatchers and proximate, vitamin and mineral composition of various American oystercatcher prey species were determined as baseline data for assessment of nutritional status. Bird and prey species samples were collected from Cape Romain Region, South Carolina and the Altamaha River Delta Islands where breeding populations appear stable. Circulating vitamin A levels in birds were higher than ranges reported as normal for domestic avian species and vitamin D concentrations were lower than anticipated based on values observed in poultry. Vitamin E levels were within ranges previously reported for avian groups with similar feeding niches. Prey species (oysters, mussels, clams, whelks, blood arks, false angel wings) were similar in water content to vertebrate prey, moderate to high in protein and moderate to low in crude fat. Ash and macronutrient concentrations in prey species were high compared to requirements of carnivores or avian species. Prey items analyzed appear to meet nutritional requirements for oystercatchers, as estimated by extrapolation from domestic carnivores and poultry species; excesses, imbalances and toxicities – particularly of minerals and fat-soluble vitamins – may be more of an issue warranting further investigation.

People and Nature. https://doi.org/10.1002/pan3.10443 \| Abstract	February 2023	Human-wildlife conflict, where interactions have negative impacts on both people and animals, is complex with underlying drivers and broad ecological and social impacts. From individual incidents and perceptions, to contemporary patterns and long-term trends, a range of information about human-wildlife conflict can help understand and manage challenges. However, many studies focus on a single data type or spatiotemporal scale. In the Western Okavango Panhandle in Botswana, people in rural farming communities share and compete for resources with a growing African savanna elephant population. Few previous studies have focused on human-wildlife interactions in this region. We assessed spatiotemporal trends in human-elephant conflict using reported conflict incidents (2008–2016), surveys of individual perceptions of conflict encompassing the late 1990s–2016, and detailed field raid assessments from 2016. We found complementary patterns among the data types at different geographic and spatial scales. We found that the number of annual HEC incidents have increased over time, although not evenly across space, with increases primarily in the northern region of the Panhandle. Crop raiding presents both chronic and acute challenges for farmers, with the amount of damage incurred per incident largely dependent on the size of elephant group involved rather than factors within the farmers' control such as guarding or types of crops grown. Our results provide a characterization of contemporary conflict incidents and long-term trends, despite scarce historical data. Combining the reporting and assessment data with surveyed local ecological knowledge offered a multidimensional understanding of human-wildlife conflict for a region where this information was lacking. It is an important precursor to effective and collaborative conflict management and mitigation. When possible, this mixed-methods approach may facilitate understanding for complex human-wildlife interactions and support the diverse communities and stakeholders involved with conflict-related challenges.

Landscape Ecology. https://doi.org/10.1007/s10980-022-01581-y. \| Abstract	April 2023	Minimizing negative impacts of wildfire is a major societal objective in fire-prone landscapes. Models of fire connectivity can aid in understanding and managing wildfires by analyzing potential fire spread and conductance patterns. We define ‘fire connectivity’ as the landscape’s capacity to facilitate fire transmission from one point on the landscape to another. Our objective was to develop an approach for modeling fire connectivity patterns representing potential fire spread and relative flow across a broad landscape extent, particularly in the management-relevant context of fuel breaks. We applied an omnidirectional circuit theory algorithm to model fire connectivity in the Great Basin of the western United States. We used predicted rates of fire spread to approximate conductance and calculated current densities to identify connections among areas with high spread rates. We compared existing and planned fuel breaks with fire connectivity patterns. Fire connectivity and relative flow outputs were characterized by spatial heterogeneity in the landscape’s capacity to transmit fire. We found that existing fuel break networks were denser in areas with relatively diffuse and impeded flow patterns, rather than in locations with channelized flow. This approach could be paired with traditional fire behavior and risk analyses to better understand wildfire spread as well as direct strategic placement of individual fuel breaks within larger networks to constrain fire spread. Thus, our findings may offer local- to landscape-level support for management actions that aim to disrupt fire spread and mitigate the costs of fire on the landscape.

Biological Invasions. doi.org/10.1007/s10530-022-02945-w \| Abstract \| Publisher Website	January 2023	The spatial context of invasions is increasingly recognized as important for the success and efficiency of management actions. This information can be key for managing invasive grasses that threaten native ecosystems. While methods for quantifying invasive grass presence and abundance advance, few options have been explored in characterizing and comparing spatial patterns of extent and connectivity. We calculated landscape metrics and circuit-based centrality for invasive grasses using a weighted-average product (30m resolution) in the Great Basin, USA. We found variation among extent metrics (mean class and patch area, number of patches, largest patch index) and connectivity metrics (nearest neighbor, contiguity, aggregation index, centrality); most of the extent and connectivity metrics were not strongly correlated with dominant abundance class and so provided additional information at the sampled grid and local scales. We also illustrated how thresholding relevant metrics could be used to identify areas needing different management strategies, for example, where strategies could proactively protect uninvaded cores, disconnect fine fuel patches, or contain established invasions. The landscape metric approach can be applied across scales to spatially target patches locally, provide broader context within a single region, as well as to compare metrics and spatial variation in patterns among different regions.

Land, 12(6), 1176. https://doi.org/10.3390/land12061176 \| Abstract	June 2023	The sagebrush biome within the western United States has been reshaped by disturbances, management, and changing environmental conditions. As a result, sagebrush cover and configuration have varied over space and time, influencing processes and species that rely on contiguous, connected sagebrush. Previous studies have documented changes in sagebrush cover, but we know little about how the connectivity of sagebrush has changed over time and across the sagebrush biome. We investigated temporal connectivity patterns for sagebrush using a time series (1985-2020) of fractional sagebrush cover and used an omnidirectional circuit algorithm to assess the density of connections among areas with abundant sagebrush. By comparing connectivity patterns over time, we found that most of the biome experienced moderate change; the amount and type of change varied spatially, indicating that areas differ in the trend direction and magnitude of change. Two different types of designated areas of conservation and management interest had relatively high proportions of stable, high-connectivity patterns over time and stable connectivity trends on average. These results provide ecological information on sagebrush connectivity persistence across spatial and temporal scales that can support targeted actions to address changing structural connectivity and to maintain functioning, connected ecosystems.

Wilson Journal of Ornithology 126:443-450. \| Abstract \| Download	July 2014	Little is known about the reproductive success of Black Skimmers (Rynchops niger) throughout the southeastern USA where availability of undisturbed beaches for nesting is limited. Daily survival rates (DSR) of nests were examined at three nesting sites in Cape Romain National Wildlife Refuge (CRNWR), South Carolina, USA, 2009–2010. The percent of successful nests (n = 346 nests) ranged from 42–69% among colony sites when data were pooled across both years. The DSR of nests was primarily related to colony site, predation risk, height of high tide, and clutch size. Predation and overwash were the principal causes of identifiable nest loss, each accounting for ~33% of nest failures during the 2 study years. Because of the challenges of resighting skimmer chicks, we were not able to measure chick survival effectively and therefore accurate measures of productivity remain elusive. High variability in nest success among sites within close proximity to each other (<20km) suggests factors at local scales such as disturbance, predation, and overwash events strongly influenced nest success of Black Skimmers during these 2 years as opposed to more region-wide stressors such as tropical storms or food availability. Although time-intensive techniques to control predators do exist, management options to limit flooding and overwash are far more limited. Conservation of Black Skimmers in the southeastern USA would benefit from coordinated, multi-state efforts to measure nest and chick survival

Freshwater Biology, 68(3), 437-451. \| Abstract	March 2023	<b>Abstract:</b><br><i>Aims</i>: When investigating community assembly, functional differences among species are assumed to be as important as environmental differences between sites in determining β-diversity. However, few studies have examined the influence of functional diversity on β-diversity. Our study examines the relative importance of regional functional diversity partitioned by niche dimensions and environmental variation in structuring β-diversity of stream fishes using a large dataset.<br><i>Location</i>: One hundred and sixty-eight watersheds in the eastern United States.<br><i>Time period</i>: 1990 to 2013<br><i>Major taxa studied</i>: Freshwater fishes (Teleostei)<br><i>Methods</i>: We predicted that both functional diversity and environmental variation play a role in determining β-diversity. We tested this prediction by modeling the patterns of stream fish β-diversity as a function of environmental variation, functional diversity, and γ-richness across 10,220 sites for 329 fish species using a series of conceptual path models.<br><i>Results</i>: Environmental variation consistently affected β-diversity across all models, while functional diversity and γ-richness influenced β-diversity only in some models. We show that including relevant trait differences among species in path models can improve their ability to explain β-diversity, suggesting that functional traits played a role in determining β-diversity.<br><i>Main conclusions</i>: The ability of path models to predict β-diversity varied depending on the trait grouping included in the model, demonstrating how specific path models representing different niche dimensions can improve the model’s ability to explain β-diversity. Additionally, parsing traits into different niche dimensions revealed alternate patterns of functional diversity-β-diversity relationships that have been otherwise missed.

Bower, L. M., & Peoples, B. K. (2022). Microhabitat use of larval fish in a South Carolina Piedmont stream. Journal of Freshwater Ecology, 37(1), 583-596. \| Abstract	November 2022	Understanding habitat use and nursery areas of larval fish is a key component to managing and conserving riverine fishes. Yet, freshwater researchers often focus only on adult fishes, resulting in a limited understanding of the habitat requirements for the early life stages of freshwater fishes. The goal of this study was to quantify the larval fish microhabitat use of three fish families in Twelvemile Creek, a fifth-order tributary of Lake Hartwell (Savannah River basin) in the Piedmont ecoregion of South Carolina, USA. We used handheld dipnets to sample larval fishes along 20 equidistant transects spaced 10 m apart weekly from May to July 2021 along a 200 m stream reach. We also collected microhabitat data at each larval fish capture location. Most captured individuals were in the metalarval stage and were identified to the family level. A partial distance-based redundancy analysis indicated that water velocity contributed to changes in larval fish assemblage structure. Larval fishes occupied a subset of the available habitat that was characterized by low water velocity, non-<i>Podostemum</i> substrate, and shallow habitats close to the shore or bed rock structure. We also detected temporal patterns in larval fish counts, with peak Percidae and Leuciscidae counts in late July and the highest Catostomidae counts in late May–early June. Our results suggest that larval fishes select habitats with low water velocity and shallow habitats close to shore microhabitat characteristics, and that riffle-pool sequences may serve as a nursery habitat for Percidae, Catostomidae and Leuciscidae metalarvae.

Lawson, A.J., P.G.R. Jodice. 2015. Do changes in size class composition influence ontogenetic niche shifts in American alligators? Ecological Society of America Annual Meeting. Baltimore, Maryland.	September 2015	We sought to determine if population size class composition and habitat use differed in American alligators prior to the implementation of, and then during harvesting periods (i.e., years). The increase in the largest size classes over time in combination with a lack of change in habitat selection patterns in smaller size classes suggests that social dominance likely continues to influence spatial segregation of size classes.
Lawson, A.J., P.G.R. Jodice, and C.T. Moore. 2019. Synthesizing monitoring data to estimate abundance and detection probability in American alligators in South Carolina. Southeastern Assoc Fish & Wildlife Agencies.	October 2019	Alligator demographic parameter estimates are difficult to obtain due to their large body size, long lifespan (80+ years), and highly wary behavior towards common monitoring methodology. We synthesized mark-recapture, harvest, nesting, and replicated count data from South Carolina to develop the first-known integrated population model (IPM) for alligators.
Lawson, A.J., K.W. McFadden, P.G.R. Jodice. 2015. Does harvest pressure influence body size class composition in American alligator populations? The Wildlife Society Annual Meeting. Winnipeg, Manitoba.	October 2015	We examined alligator nightlight survey data from coastal South Carolina during 1971-1995 (pre-harvest) and 1996-2015 (post-harvest). Our preliminary findings indicate that the annual average body length of harvested alligators decreased significantly from 2008 to 2013, while the proportion of juvenile size classes decreased and the proportion of adults increased.

Lawson, A., P. Jodice, T. Rainwater, K.W. McFadden. Evaluating American alligator home range size and site fidelity patterns in artificial wetlands. International Congress for Conservation Biology; Cartagena, Colombia.	July 2017	Movement patterns have profound implications for both conservation decisions, and many ecological processes like species abundance and distribution, and predator-prey interactions. South Carolina alligator home range sizes and movement rates were similar in artificial wetlands to previous studies in natural wetland systems, suggesting that in some cases, artificial habitats may not significantly alter alligator movement behavior.

Lamb, J.S., Y.G. Satgé, P.G.R. Jodice. 2017. Movement patterns and habitat selection of Brown Pelicans in the Gulf of Mexico. Pacific Seabird Group Annual Meeting, Tacoma, Washington.	February 2017	We assessed year-round habitat selection and use by Brown Pelicans nesting in the northern Gulf of Mexico based on three years of GPS data from 85 individuals. Although previous studies have suggested that nearshore seabirds are influenced by both temperature and productivity of oceanic waters, salinity is an unusual component of seabird habitat selection and may be driven in this system by an abundance of estuarine-dependent prey.
Lamb, J., and P. Jodice. 2015. Sex, death, and oil: Conservation implications of individual and geographic variation in Brown Pelican movement patterns. 2nd World Seabird Conference, Cape Town, South Africa.	October 2015	We modeled breeding and nonbreeding movement patterns, migratory strategy, and environmental characteristics of at-sea habitat of Brown Pelicans as a function of both individual characteristics and breeding colony locations. We found that extensive postbreeding movements and use of offshore habitat resulted in significant increases in exposure to oil infrastructure outside the breeding area, suggesting that determination of nonbreeding habitat use is an important component of conservation plann
Lamb, J., Y. Satge, P.G.R. Jodice. 2015. Variation in Brown Pelican energy provisioning rates across a range of juvenile forage fish availability. Waterbird Society Annual Meeting, Bar Harbor, Maine.	August 2015	Although prey availability is considered a key driver of seabird nest productivity, it is often difficult to quantify since many forage fish species and life stages are not targeted by commercial fisheries. We suggest that availability and accessibility of juvenile menhaden are the key factors driving energy provisioning rates and fledging success of Brown Pelicans in the western Gulf of Mexico.
Lamb, J.*, P.G.R. Jodice. 2015. Should I stay or should I go? Physiology and geography predict individual migratory strategies in the brown pelican. Pacific Seabird Group Annual Meeting, San Jose, California.	February 2015	Neither body condition nor breeding success influenced migratory strategy in pelicans, although failed breeders often dispersed away from breeding colonies immediately following nest failure. Long-distance migrants were also less likely than residents or medium-distance migrants to breed in the second season of data collection, which may indicate a biannual breeding strategy in a portion of the population.

International Marine Conservation Congress, Glasgow, Scotland [Poster].	August 2014	we used GPS technology to track Brown Pelicans breeding in the Eastern, Central, and Western Gulf of Mexico through a full annual cycle. We found that the extent of spatial overlap between pelican habitat and energy installations varied between regions, individuals, and seasons.
Lamb, J.*, P.G.R. Jodice. 2014. Gradients in breeding Brown Pelican forging radius, chick condition, and diet across the Northern Gulf of Mexico. Pacific Seabird Group Annual Meeting, Juneau, Alaska.	February 2014	Unlike pelagic seabirds whose foraging habitat is generally distant from human development, the Brown Pelican (Pelecanus occidentalis) relies on coastal habitats along undeveloped to heavily-developed shorelines. Preliminary results indicate that breeding-season foraging radius of adults increased from east (Florida Panhandle) to west (southern Texas), while chick body condition declined along the same gradient.
Lamb, J.*, P.G.R. Jodice. 2014. Comparative performance of cellular and satellite transmitters deployed on Brown pelicans in the Northern Gulf of Mexico. Pacific Seabird Group Annual Meeting, Juneau, Alaska.	February 2014	Cellular Terminal GPS Transmitters (GSM Transmitters, or CTTs) have recently become available as an alternative to traditional Platform Terminal Transmitters (PTTs), which transmit data through the Argos satellite system. CTT units offer several advantages over PTTs, including reduced data transmission costs, improved data access, and a two-way interface that allows the tag to be reprogrammed after deployment. However, their performance in the field has not yet been tested.

The Waterbird Society, New Bern, North Carolina.	September 2016	While the number of young produced per nesting pair (i.e., fledging success) is often used as a proxy for recruitment in seabird populations, post-fledging survival is likely to be much lower than this estimate suggests. To assess inter- and intra-colony variation in nestling condition, we collected measures of short-term (body condition index: i.e., relationship of mass to skeletal size) and long-term (corticosterone levels in contour feathers) physical condition of 3-6 week-old chicks from pe

Society for Integrative and Comparative Biology, Portland, Maine.	January 2016	To assess inter- and intra-colony variation in nestling condition, we collected measures of short-term (relationship of mass to skeletal size) and long-term (corticosterone levels in body feathers) physical condition of 3-6 week-old chicks from pelican colonies across the northern Gulf of Mexico over a three-year period. Since elevated stress levels during development are known to affect lifetime survival and reproductive fitness, we suggest nestling feather corticosterone as a useful index of

Waterbird Society Annual Meeting, La Paz, Mexico.	November 2014	The Tehuantepec Isthmus, which spans portions of Veracruz and Oaxaca, Mexico, represents the shortest distance between the Gulf of Mexico and the Pacific Ocean. We present information from recent tracking studies and band re-sightings of individual Brown Pelicans (n=3), Red Knots (n=5), and Reddish Egrets (n=3) captured in the Northern Gulf of Mexico that used the Tehuantepec region as either a movement corridor or migratory stopover.

Elucidating the hierarchical relationships between mechanisms of stream fish taxonomic compositional change. The American Fisheries Society Meeting. Grand Rapids, Michigan. 21 August 2023.	August 2023	This study seeks to untangle the hierarchical relationships between the drivers of stream fish community homogenization across the conterminous United States using a community dataset spanning the conterminous US. We expect to find a greater contribution of nonnative richness to taxonomic change and complex direct and indirect effects of the invasion/extirpation drivers on each other as well as on nonnative richness and extirpations.

An integrated approach to building capacity for seabird conservation in the Caribbean - a success story. 2nd World Seabird Conference, Cape Town, South Africa	October 2015	Between 2011-13 the Seabird Working Group (SWG) of Birds Caribbean (BC) undertook a 3 year capacity building project supported by the National Fish and Wildlife Foundation. We implemented 3 capacity-building training workshops with participants from >15 islands; produced a Caribbean seabird monitoring manual in English and Spanish; and provided >10 small grants that enabled participants to begin programs in their islands with mentoring from long-distance experts.
Adams, M., Tegeler, A., Hook, M., Small, M., & Ross, B.E. (2020). Effects of forest management on early-successional avian species in South Carolina. The Wildlife Society.	September 2020	This project will provide managers with occupancy estimates for ruffed grouse and golden-winged warblers in the Blue Ridge of South Carolina and this data can be used as a baseline for future population work within the state. Little work has been done to understand habitat use of ruffed grouse and golden-winged warblers at the edge of their range, so understanding the habitat use of both species in South Carolina will aid future conservation and habitat management efforts relevant to the state.

Rangewide lesser prairie-chicken population persistence with climate change. International Grouse Symposium, Logan, Utah.	September 2018	Weather events influence nearly all vital rates for lesser prairie-chickens though their effects vary by ecoregion. Our assessment of the effect of environmental conditions on population trends across the distribution of the species indicates southern populations in the MGP and SOP will have severe declines resulting in extinction for most climate projections unless managers take sufficient conservation efforts.
