2024, Canadian Journal of Fisheries and Aquatic Sciences (81) 1650-1665
Managing fisheries in a changing socio-ecological environment may require holistic approaches for identifying and adapting to novel ecosystem dynamics. Using 32 years of Ceded Territory of Wisconsin (CTWI) walleye (Sander vitreus) data, we estimated production (P), biomass (B), biomass turnover (P/B), yield (Y), and yield over production (Y/P) and tested...

Jenna R. Grimshaw, Deahn M. Donner, Roger W. Perry, W. Mark Ford, Alex Silvis, Carlos J. Garcia, Richard D. Stevens, David A. Ray
2024, Journal of Mammalogy (105) 854-864
Myotis septentrionalis (Northern Long-eared Bat) has recently suffered a >90% decline in population size in North America due to white-nose syndrome (WNS). We assessed genetic diversity, population structure, current effective population size, and demographic history of M. septentrionalis distributed across the United States to determine baseline levels pre-WNS. We analyzed RADseq data from...
Permafrost history in the sporadic zone as context for recent carbon loss using acryostratigraphy, plant macrofossil, and stable isotope approach
Miriam C. Jones, Lesleigh Anderson, Eva Anne Stephani, Benjamin M. Jones
2024, Conference Paper, 12th International conference on permafrost, proceedings
Permafrost and landscape history, in addition to ground ice content, are increasingly identified as important components in predicting permafrost thaw trajectories. Together with cryostratigraphy, plant remains and stable isotopes can provide useful information about past permafrost aggradation and thaw. We applied these methods with radiocarbon dating on peat and permafrost...

Larval coregonine density and diet composition along beaches of northern Lake Michigan
Marissa Cubbage, Tomas O. Hook, David Bunnell, Patricia Dieter, Amanda Susanne Ackiss, Paris D. Collingsworth
2024, Journal of Great Lakes Research (50)
Recent oligotrophication in Lake Michigan has contributed to reduced biomass of spring zooplankton and a shift in the zooplankton assemblage toward more calanoid copepods. These changes have likely altered prey availability for first feeding native fish species that hatch in early spring, including coregonines. While spring zooplankton density and community...

Alexis Will, Heather McFarland, Christopher Latty, Abby Powell
2024, Avian Conservation and Ecology (19)
Climate change is having a disproportionate impact on the Arctic. For Arctic breeding birds, basic knowledge of their annual cycle, specifically the timing, route, and movement behavior of migration, is needed to understand when and where populations may experience threats. We used a combination of geolocators and stable isotope analysis...

Effective field sampling of rectoanal mucosa-associated lymphoid tissue for antemortem chronic wasting disease testing in white-tailed deer
Marie L. J. Gilbertson, Lindsey J. Long, Heather N. Inzalaco, Wendy Christine Turner, Daniel J. Storm
2024, Journal of Wildlife Diseases (60) 996-1003
Chronic wasting disease (CWD) is a fatal prion disease of cervids that has spread across much of North America. Although gold standard CWD diagnostics involve postmortem testing of medial retropharyngeal lymph nodes or obex (brain stem), a key tissue sample for antemortem testing is rectoanal mucosa–associated lymphoid tissue (RAMALT). However,...

2024, Hydrological Sciences Journal (69) 1387-1398
Low-flow period properties, including timing, magnitude, and duration, influence many key processes for water resource managers and ecosystems. We computed annual low-flow period duration and timing metrics from 1951 to 2020 for 1032 conterminous United States (CONUS) streamgages and analyzed spatial patterns, trends through time, and relationships to climate.

Kendall L. Calhoun, Thomas Connor, Kaitlyn M. Gaynor, Amy Van Scoyoc, Michael C Mcinturff, Samantha E.S. Kreling, Justin S. Brashares
2024, Movement Ecology (12)
BackgroundMovement plays a key role in allowing animal species to adapt to sudden environmental shifts. Anthropogenic climate and land use change have accelerated the frequency of some of these extreme disturbances, including megafire. These megafires dramatically alter ecosystems and challenge the capacity of several species to adjust to...
