2022, Forest Ecology and Management (508)
Forested stream ecosystems involve complex physical and biotic pathways that can influence fish in numerous ways. Consequently, the responses of fish communities to disturbance can be difficult to understand. In this study, we employed a food web model that links biotic...
Where groundwater seeps: Evaluating modeled groundwater discharge patterns with thermal infrared surveys at the river-network scale
Janet R. Barclay, Martin A. Briggs, Eric Moore, J. Jeffrey Starn, Ann E.H. Hanson, Ashley Helton
2022, Advances in Water Resources (160)
Predicting baseflow dynamics, protecting aquatic habitat, and managing legacy contaminants requires explicit characterization and prediction of groundwater discharge patterns throughout river networks. Using handheld thermal infrared (TIR) cameras, we surveyed 47 km of stream length across the Farmington River watershed (1,570 km2; CT...

2022, Evolution (76) 346-356
Sex‐related differences in mortality are widespread in the animal kingdom. Although studies have shown that sex determination systems might drive lifespan evolution, sex chromosome influence on aging rates have not been investigated so far, likely due to an apparent lack of demographic data from clades including both XY (with...
Modelling physiological costs to assess impacts of climate change on amphibians in Yellowstone National Park, U.S.A
Paul E. Bartelt, Peter E. Thornton, Robert W. Klaver
2022, Ecological Indicators (135)
Amphibians are vital elements of ecosystems, serving as predator and prey. Their biphasic nature makes them dependent on aquatic and terrestrial habitats; as wet-skinned ectotherms, they are vulnerable to a range of environmental threats, including climate change. Yellowstone National Park (YNP) is becoming warmer and drier, and some wetlands important...

Erik J. Blomberg, Beth Ross, Casey J. Cardinal, Susan N. Ellis-Felege, Daniel Gibson, Adrian P. Monroe, P Schwalenberg
2022, Ornithological Applications (124)
The Migratory Bird Treaty Act (MBTA) is critical to avian conservation in the United States, both through its protection of migratory birds and as a catalyst for a century of coordinated avian conservation. While more than 1,000 species are protected by MBTA, of extant bird species native to the continental...
Estimating bee abundance: Can mark-recapture methods validate common sampling protocols?
Emma L. Briggs, Christopher Baranski, Olivia Munzer Schaetz, Gabriela Garrison, Elsa Youngsteadt, Jaime A. Collazo
2022, Apidologie (53)
Wild bees are essential pollinators in natural and agricultural systems, but populations of some species have declined. Efforts to assess the status of wild bees are hindered by uncertainty in common sampling methods, such as pan traps and aerial netting, which may or may not provide a valid index of...
Climate change adaptation thinking for managed wetlands
John Delaney, Kristen L. Bouska, Josh D. Eash
2022, Open-File Report 2021-1103
Climate change presents new and ongoing challenges to natural resource management. To confront these challenges effectively, managers need to develop proactive adaptation strategies to prepare for and deal with the effects of climate change. We engaged managers and biologists from several midwestern U.S. Fish and Wildlife Service field stations to...

2022, Conservation Science and Practice (4)
The southern sea otter (Enhydra lutris nereis) is a threatened sub-species in coastal ecosystems.

Loss of phylogenetic diversity under landscape change
Christopher M. Swan, Matthew Baker, Dorothy Borowy, Anna Johnson, Mariya Shcheglovitova, April Sparkman, Francisco V. Neto, Molly Van Appledorn, Nicole Voelker
2022, Science of the Total Environment (822)
Habitat alteration and destruction are primary drivers of biodiversity loss. However, the evolutionary dimensions of biodiversity loss remain largely unexplored in many systems. For example, little is known about how habitat alteration/loss can lead to phylogenetic deconstruction of ecological assemblages at the local level. That is, while species loss is evident, are...

Genetic processes facilitating pathogen emergence
N. J. Grunwald, C. E. Brown, Hon S. Ip, J. H. Chang
Kitty F. Cardwell, Keith L. Bailey, editor(s)
2022, Book chapter, Tactical sciences for biosecurity in animal and plant systems
The goal of biosecurity is to minimize the risk of introduction and transmission of infectious diseases to people, animals, and plants. This is achieved by accurately identifying pathogens and instituting appropriate methods to prevent their introduction, reemergence, and/or spread. However, disease is dynamic, and biosecurity needs to continually change to...

Climate change is transforming ecosystems and affecting ecosystem goods and services. Along the Gulf of Mexico and Atlantic coasts of the southeastern United States, the frequency and intensity of extreme freeze events greatly influences whether coastal wetlands are dominated by freeze-sensitive woody plants (mangrove forests) or freeze-tolerant grass-like plants (salt...

In this study, we explore the characteristics of people’s...
A conterminous USA-scale map of relative tidal marsh elevation
James R. Holmquist, Lisamarie Windham-Myers
2022, Estuaries and Coasts (45) 1596-1614
Tidal wetlands provide myriad ecosystem services across local to global scales. With their uncertain vulnerability or resilience to rising sea levels, there is a need for mapping flooding drivers and vulnerability proxies for these ecosystems at a national scale. However, tidal wetlands in the conterminous USA are diverse with differing...

Bear diets and human-bear conflicts: Insights from isotopic ecology
Nereyda Falconi, Tomas A. Carlo, Todd K. Fuller, Stephen DeStefano, John F. Organ
2022, Mammal Review (52) 322-327
Bears, Ursidae, are considered omnivores, except for giant pandas Ailuropoda melanoleuca and polar bears Ursus maritimus. However, omnivory includes a wide range of dietary variation and trophic positions, making bear dietary ecology unclear. We inferred bear trophic positions from δ15N (‰) values and examined their correlation with diets reported in the literature, including...
High densities of conspecifics buffer native fish from negative interactions with an ecologically similar invasive
Casey A. Pennock, W. Carl Saunders, Phaedra E. Budy
2022, Biological Invasions (24) 1283-1297
Invasive species are a leading cause for native species declines, but it remains unclear whether maintenance of high native densities influence native persistence in freshwater systems. We designed complementary laboratory and field experiments to test whether high native cutthroat trout (Oncorhynchus clarkii) densities affect competition with invasive brown trout...
Tracking spatial regimes in animal communities: Implications for resilience-based management
Caleb Powell Roberts, Daniel R. Uden, Craig R. Allen, David G. Angeler, Larkin A. Powell, Brady W Allred, Matthew O. Jones, Jeremy D Maestas, Dirac Twidwell
2022, Ecological Indicators (136)
Spatial regimes (the spatial extents of ecological states) exhibit strong spatiotemporal order as they expand or contract in response to retreating or encroaching adjacent spatial regimes (e.g., woody plant invasion of grasslands) and human management (e.g., fire treatments). New methods enable tracking spatial regime boundaries via vegetation landcover data, and...
