Assessment and characterization of ephemeral stream channel stability and mechanisms affecting erosion in Grand Valley, western Colorado, 2018–21
Joel William Homan
2024, Scientific Investigations Report 2023-5145
The Grand Valley in western Colorado is in the semiarid Southwest United States. The north side of the Grand Valley has many ungaged ephemeral streams, which are of particular interest because (1) the underlying bedrock geology, Late Cretaceous Mancos Shale, is a sedimentary rock deposit identified as a major salinity...
Fluviomorphic trajectories for dryland ephemeral stream channels following extreme flash floods
Eliisa Lotsari, Kyle House, Petteri Alho, Victor R. Baker
2024, Earth Surface Processes and Landforms
Ephemeral alluvial streams pose globally significant flood hazards to human habitation in drylands, but sparse data for these regions limit understanding of the character and impacts of extreme flooding. In this study, we document decadal changes in dryland ephemeral channel patterns at two sites...

Sharon Poessel, Elise Elliott-Smith, Sean M. Murphy, Susan M Haig, Adam E. Duerr, Todd E. Katzner
2024, Avian Conservation and Ecology (19)
Long-billed Curlews (Numenius americanus) are declining throughout North America, and the loss of grassland breeding habitat is one of the primary threats to the species. Intermountain West, in particular, has been identified as the most important region in North America for breeding curlews. Nevertheless, the density and abundance of Long-billed...
Accounting for the fraction of carcasses outside the searched area in the estimation of bird and bat fatalities at wind energy facilities
Daniel Dalthorp, Manuela Huso, Mark Dalthorp, Jeffrey Mintz
2024, Techniques and Methods 7-A3
Accurate estimation of bird and bat mortality at wind energy facilities requires accounting for carcasses that lie outside the search plots because they lie beyond the search radius or in areas within the search radius that remain unsearched due to sub-optimal search conditions such as thick vegetation, rough or dangerous...

2024, Herpetological Conservation and Biology (19) 96-105
Understanding the geographical range of a species is essential to successful conservation and management, but their ranges are not always fully known. Ringed Map Turtles (Graptemys oculifera) have been federally listed as a Threatened species since 1986, and they have long been considered endemic to the Pearl River system...

Patrick Kroboth, Benjamin H. Stahlschmidt, Duane Chapman
2024, Journal of Applied Ichthyology (2024)
Black carp Mylopharyngodon piceus (Richardson, 1846) have been widely used as biological control of snails in aquaculture and were imported to the United States in the 1970s and 1980s for this purpose. Prior research emphasizes the species’ propensity to control gastropods, but since subsequent escape and establishment of black carp...

Clarke Alexandra Knight, Lysanna Anderson, Liubov S. Presnetsova, Marie Rhondelle Champagne, David Wahl
2024, Nature Communications Earth and Environment (5)
Atmospheric rivers are associated with some of the largest flood-producing precipitation events in western North America, particularly California. Insight into past extreme precipitation can be reconstructed from sedimentary archives on millennial timescales. Here we document atmospheric river activity near Leonard Lake, California, over 3,200 years, using...
