Lessons learned from using wild-caught and captive-reared lesser scaup (Aythya affinis) in captive experiments
C.R Beach, C.N Jacques, J.D. Lancaster, D.C. Osborne, A.P. Yetter, Rebecca A. Cole, H.M. Hagy, A.M.V. Fournier
2024, Translational Animal Science (8)
Waterfowl are housed in captivity for research studies that are infeasible in the wild. Accommodating the unique requirements of semi-aquatic species in captivity while meeting experimental design criteria for research questions can be challenging and may have unknown effects on animal health. Thus, testing and standardizing best husbandry and...
Linking dissolved organic matter composition to landscape properties in wetlands across the United States of America

2024, Global Biogeochemical Cycles (38)
Wetlands are integral to the global carbon cycle, serving as both a source and a sink for organic carbon. Their potential for carbon storage will likely change in the coming decades in response to higher temperatures and variable precipitation patterns. We characterized the dissolved organic carbon (DOC)...
Stony coral tissue loss disease indirectly alters reef communities
Sara D. Swaminathan, Kevin D. Lafferty, Nicole S. Knight, Andrew H. Altieri
2024, Science Advances (10)
Many Caribbean coral reefs are near collapse due to various threats. An emerging threat, stony coral tissue loss disease (SCTLD), is spreading across the Western Atlantic and Caribbean. Data from the U.S. Virgin Islands reveal how SCTLD spread has reduced the abundance of susceptible coral and crustose coralline algae and...
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...

James Peterson, Erin McCreless, Adam Duarte, Patti Wohner, Scott Hamilton, Josue Medellín-Azuara, Alvar Escriva-Boue
2024, Environmental Science and Policy (103775)
A structured decision making (SDM) approach can help evaluate tradeoffs between conservation and human-benefit objectives by fostering communication and knowledge transfer among stakeholders, decision makers, and the public. However, the process is iterative and completing the full process may take...
A new era of genetic diversity conservation through novel tools and accessible data
Margaret Hunter, Jessica M. da Silva, Alicia Mastretta-Yanes, Sean M. Hoban
2024, Frontiers in Ecology and the Environment (22)
As the foundation of biodiversity, genetic diversity is necessary for species to adapt to ecological changes, such as impacts from disease, invasive species, and climate change. Genetic diversity also supports ecosystem resilience and societal innovations. Unfortunately, declines in genetic diversity have been frequently observed in populations of wild and domestic...
Lead poisoning of raptors: State of the science and cross-discipline mitigation options for a global problem

Abundance of Long-billed Curlews on military lands in the Columbia Basin
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...

Investigating past earthquakes with coral microatolls
Belle E. Philibosian
2024, Past Global Changes (PAGES) Magazine (32) 22-23
Intertidal corals (microatolls) preserve evidence of past uplift or subsidence with annual precision. Microatoll records are particularly useful along subduction zones, and can reveal past earthquake ruptures at a level of detail that is ordinarily limited to the instrumental era....

Coastal bird populations in North America have experienced significant population declines over the past four decades, and many species have become dependent upon human-made islands and other sediment-based habitats created through dredged material deposition. We monitored the breeding phenology of coastal bird populations utilizing...
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...

Late-Quaternary surface displacements on accretionary wedge splay faults in the Cascadia Subduction Zone: Implications for megathrust rupture
Anna Ledeczi, Madeleine Lucas, Harold Tobin, Janet Watt, Nathaniel C. Miller
2024, Seismica (2)
Because splay faults branch at a steep dip angle from the plate-boundary décollement in an accretionary wedge, their coseismic displacement can potentially result in larger tsunamis with distinct characteristics compared to megathrust-only fault ruptures, posing an enhanced hazard to coastal communities. Elsewhere, there is evidence of coseismic slip on splay...
NEWTS1.0: Numerical model of coastal Erosion by Waves and Transgressive Scarps
Rose Elizabeth Palermo, J. Taylor Perron, Jason M. Soderblom, Samuel P. D. Birch, Alexander G. Hayes, Andrew D. Ashton
2024, Geoscientific Model Development (17) 3433-3445
Models of rocky-coast erosion help us understand the physical phenomena that control coastal morphology and evolution, infer the processes shaping coasts in remote environments, and evaluate risk from natural hazards and future climate change. Existing models, however, are highly complex, are computationally expensive, and depend on many input parameters; this...
