Nicholas J. Kalen, Michael S. Muthersbaugh, Joshua B. Johnson, Alexander Silvis, W. Mark Ford
2022, Journal of the Southeastern Association of Fish and Wildlife Agencies (9) 159-167
Northern long-eared bat (Myotis septentrionalis) populations have experienced severe declines in eastern North America from white-nose syndrome (WNS), yet potential secondary effects on maternity roosting and recruitment remain largely unknown. We documented female day- roosting at two locations in the central Appalachians of Virginia, Back Creek Mountain (BCM) and Rapidan Camp...
Multiple resource limitation of dryland soil microbial carbon cycling on the Colorado Plateau
Ryan T. Choi, Sasha C. Reed, Colin Tucker
2022, Ecology (103)
Understanding interactions among biogeochemical cycles is increasingly important as anthropogenic alterations of global climate and of carbon (C), nitrogen (N), and phosphorus (P) cycles interactively affect the Earth system. Ecosystem processes in the dryland biome, which makes up over 40% of Earth's terrestrial surface, are often distinctively sensitive to small...

2022, Journal of the Southeastern Association of Fish and Wildlife Agencies (9) 168-175
In the central Appalachians of Virginia and West Virginia, the Virginia northern flying squirrel (Glaucomys sabrinus fuscus; VNFS) is a subspecies of northern flying squirrel generally associated with red spruce (Picea rubens)-dominated forests at high elevations. Listed as endangered by theU.S. Fish and Wildlife Service from 1985 to 2013, the...
Predicting geothermal favorability in the western United States by using machine learning: Addressing challenges and developing solutions
Stanley Paul Mordensky, John Lipor, Jacob DeAngelo, Erick R. Burns, Cary Ruth Lindsey
2022, Conference Paper, Proceedings, 47th workshop on geothermal reservoir engineering
Previous moderate- and high-temperature geothermal resource assessments of the western United States utilized weight-of-evidence and logistic regression methods to estimate resource favorability, but these analyses relied upon some expert decisions. While expert decisions can add confidence to aspects of the modeling process by ensuring only reasonable models are employed, expert...
Interannual colony exchange among breeding Eastern Brown Pelicans
Bradley P. Wilkinson, Patrick G.R. Jodice
2022, Journal of Field Ornithology (93)
Colonial seabirds often display high rates of interannual site fidelity to breeding locations, especially as adults. Species using more nearshore or coastal systems, however, may display comparatively less fidelity than highly pelagic species. We used long-term GPS tracking data to assess the frequency of interannual colony switching in Eastern Brown...
