Due to their limited geographic distributions and specialized ecologies, cave species are often highly endemic and can be especially vulnerable to habitat degradation within and surrounding the cave systems they inhabit. We investigated the evolutionary history of the West Virginia Spring Salamander (Gyrinophilus subterraneus), estimated the population trend from historic...

Corbin J. Schuster, Taylor Kreul, Colleen E. Al-Samarrie, James Peterson, Justin L. Sanders, Michael L. Kent
2022, Journal of Fish Diseases (45) 1463-1475
Pseudoloma neurophilia is a critical threat to the zebrafish (Danio rerio) model, as it is the most common infectious agent found in research facilities. In this study, our objectives were two-fold: (1) compare the application of diagnostic tools for P. neurophilia and (2) track the progression of infection using PCR and histology. The...

2022, Rocky Mountain Geology (57) 1-21
We report new LA-ICPMS U-Pb detrital zircon ages and sedimentary petrology of silty to sandy limestones and dolostones, as well as calcareous to dolomitic sandstones of the Devonian-Carboniferous (Mississippian) Chaffee Group, as well as detrital zircon ages from the Late Cambrian Sawatch Quartzite and a U-Pb zircon crystallization age on...
Integrating monitoring and optimization modeling to inform flow decisions for Chinook salmon smolts
Patti J. Wohner, Adam Duarte, John Wikert, Brad Cavallo, Steven C. Zeug, James Peterson
2022, Ecological Modelling (471)
Monitoring is usually among the first actions taken to help inform recovery planning for declining species, but these data are rarely used formally to inform conservation decision making. For example, Central Valley Chinook salmon were once abundant, but anthropogenic activities have led to widespread habitat loss and degradation resulting in...
Wading bird foraging on a wetland landscape: A comparison of two strategies
Hyo Won Lee, Donald L. DeAngelis, Simeon Yurek, Stephen Tennenbaum
2022, Mathematical Biosciences and Engineering (19) 7687-7718
Tactile-feeding wading birds, such as wood storks and white ibises, require high densities of prey such as small fishes and crayfish to support themselves and their offspring during the breeding season. Prey availability in wetlands is often determined by seasonal hydrologic pulsing, such as in the subtropical Everglades, where spatial...

2022, Nature--Scientific Data (9)
Traditional methods to assess the probability of storm-induced erosion and flooding from extreme water levels have limited use along the U.S. West Coast where swell dominates erosion and storm surge is limited. This effort presents methodology to assess the probability of erosion and flooding for the U.S. West Coast from...
Endemic Guadalupe bass (Micropterus treculii) are supported by isotopically distinct resources in tributary versus mainstem river food webs
Allison A. Pease, Jessica E. Pease, Preston T. Bean, Timothy B. Grabowski
2022, River Research and Applications (38) 1654-1659
We used stable isotope analysis to investigate differences in Guadalupe bass (Micropterus treculii) resource use that might be associated with population-level variation in mainstem river versus tributary stream habitats. Guadalupe bass from mainstem sites had higher δ13C and δ15N values compared to those collected in tributaries, likely reflecting greater importance...

Comparative studies of mortality in the wild are necessary to understand the evolution of aging; yet, ectothermic tetrapods are underrepresented in this comparative landscape, despite their suitability for testing evolutionary hypotheses. We present a study of aging rates and longevity across wild tetrapod ectotherms, using data from 107 populations (77...

By land, air, and water — U.S. Geological Survey science supporting fish and wildlife migrations throughout North America
Mona Khalil, Mark Wimer, David H. Hu, Michael J. Adams, Melanie J. Steinkamp, Suzanna C. Soileau
2022, Fact Sheet 2022-3030
Countless species of animals—big game, birds, bats, insects, amphibians, reptiles, and fish—migrate to reach suitable habitats to feed, reproduce, and raise their young. Animal migrations developed over millennia commonly follow migration corridors—unique routes for each species—to move among seasonal habitats. Changes along those corridors, whether from human development (buildings, roads,...

An invasive prey provides long-lasting silver spoon effects for an endangered predator
Caroline L. Poli, Ellen P. Robertson, Julien Martin, Abby Powell, Robert J. Fletcher Jr.
2022, Proceedings of the Royal Society B (289)
The natal environment can have long-term fitness consequences for individuals, particularly via ‘silver spoon’ or ‘environmental matching’ effects. Invasive species could alter natal effects on native species by changing species interactions, but this potential remains unknown. Using 17 years of data on 2588 individuals across the entire...
