Morphology and molecular data reveal invasion of cryptic golden tegus Tupinambis cryptus Murphy et al., 2016) in Florida
Golden Tegus (Tupinambis teguixin sensu lato) are native to South America and have established a reproducing population in Miami-Dade County, Florida. Recent work divided the Golden Tegu into four separate species, leaving the specific identity of Golden Tegus in Florida unknown. We used morphometric and mitochondrial data to determine the species...
Pyron, R. Alexander; Reed, Robert; Colston, Timothy J.; Rochford, Michael R. Alaska Shorebird Conservation Plan, Version III
In recognition of declines among perhaps half of Alaska’s breeding shorebirds, ongoing or emerging threats to shorebirds and their habitats, and considerable knowledge of Alaska’s shorebirds acquired over the past decade, the Alaska Shorebird Group decided that the Alaska Shorebird Conservation Plan was due for updates. Similar to Version II (2008...
Ruthrauff, Daniel R. Three-dimensional partitioning of resources by congeneric forest predators with recent sympatry
Coexistence of ecologically similar species can be maintained by partitioning along one or more niche axes. Three-dimensional structural complexity is central to facilitating resource partitioning between many forest species, but is underrepresented in field-based studies. We examined resource selection by sympatric northern spotted owls (Strix...

A hydrological framework to improve precision of Vital Signs metrics in the Appalachian highlands
Stream flow is a fundamental driver of ecological structure and function, but its influence on bioassessment measures is poorly understood. Although extreme flow conditions (e.g., floods and droughts) have long been known to play a central role in structuring stream communities, a mechanistic understanding of the linkages between flow variables, landscape and local physical characteristics,...
Fish locomotion and biomechanics as limiting and optimizing factors in fish passage
Swimming ability determines how well fish are able to access habitat, and is a fundamental design consideration for passing fish at dams, road crossings etc. The purpose of this study plan is to improve understanding of how fish are able to negotiate zones of high velocity and turbulent flow, such as are found in fishways, culverts, as well as in natural areas. Swimming performance is...
Effects of temperature and energy use on fish passage and spawning success of American shad
American Shad are the most numerous and economically important anadromous species on the east coast of the United States. Yet in many river systems their populations have experienced declines, primarily due to the impacts of dams and habitat loss. Although fish passage facilities have been constructed to mitigate the impacts of dams, many of these have not provided adequate passage success...
Genetic connectivity among regional populations of red tree corals (Primnoa pacifica) in the North Pacific Ocean
Knowledge of the degree to which populations are connected through larval dispersal is imperative to effective management, yet little is known about larval dispersal capability or population connectivity in Primnoa pacifica, an important habitat forming octocoral on the outer continental shelf and upper slope in the Gulf of Alaska. Red tree corals can reach massive size (up to 5m...
Conservation Genetics and Genomics of the Narrowly Endemic Island Marble Butterfly Euchloe ausonides insulanus
The island marble butterfly (Euchloe ausonides insulanus) was first discovered on Vancouver Island, Canada in 1861. Based on morphological characteristics, it has been described as a subspecies of Euchloe ausonides. After a collection was made in 1908 on Gabriola Island, Canada, the island marble was not seen again until 1998 on San Juan Island, Washington, USA. Recent...
Genetic characterization of the clubshell species complex (Pleurobema clava and P. oviforme) for enhanced conservation
The diversity of freshwater mussels (family Unionidae) in the United States is unmatched in the rest of the world, yet this biodiversity is highly vulnerable, with more than 70% of recognized species considered to be either endangered, threatened, or of special concern. Most species inhabit limited ranges and have small (and/or often unknown) dispersal abilities due to reliance on specific...

Survey and Assessment of Live Food Markets as an Invasion Pathway
Live food markets may be a source of the increasing number of non-native wild invertebrate and fish species, like Asian swamp eels and snakeheads. USGS is surveying such markets around the United States to identify and document species that might be of concern if released live into the wild to assess if the live food market is a possible invasion pathway.
Climate change forecasts for eastern salmonids
Small streams in forests are likely to see dramatic shifts as global climate change influences air temperature and rain patterns. We have already seen warmer stream temperatures as air temperatures increase in summer in the Northeastern US. The intensity and duration of floods and droughts are also expected to magnify as future rain patterns shift. This project will evaluate how stream...
Use of next-generation sequencing for the dietary analyses of smallmouth bass (Micropterus dolomieu) stomach content
The USGS Leetown Science Center (USGS LSC) scientists are collaborating with the PADEP (SMB) to develop and evaluate a genetic assay for fish diets that will allow us to develop a cost-effective monitoring program for determining the diet of wild fish. We will test the utility of this method and, once fully developed, these methods could be generally applied in many other piscivorous species...
