Satellite-derived shorelines (SDS) have the potential to help researchers answer critical coastal science questions and support work to predict coastal change by filling in the spatial and temporal gaps present in current field-based and remote-sensing data collection methods. The U.S. Geological Survey conducted comparison analyses of traditionally sourced shorelines and...
Density as a mechanism linking habitat disturbance to increased pathogen prevalence: Evidence from a natural experiment
Gabriel M. Barrile, Anna D. Chalfoun, Annika W. Walters, Jerod A. Merkle
2025, Ecology (106)
Sudden habitat loss associated with environmental disturbance can trigger animals to move from affected to undisturbed areas, where increases in local density may occur. Although pathogen transmission is strongly related to local density, how crowding after habitat loss affects infection dynamics in wild populations remains unclear. Here...

Evaluating the central–marginal hypothesis: Introgression and genetic variation at the trailing edge of Quercus bicolor
Jesse B. Parker, Sean Hoban, Laura Thompson, Scott E. Schlarbaum
2025, Molecular Ecology (34)
The central–marginal hypothesis (CMH) predicts reduced genetic diversity and increased differentiation in range-edge populations due to ecological marginality and limited gene flow. Deviations from this pattern, however, can result from historical demographic processes, variation in reproductive strategies or interspecific hybridization. The genus Quercus, known for hybridization and long-distance pollination, offers an...

Jesse L De La Cruz, Sabrina M. Deeley, Elizabeth Ann Hunter, W. Mark Ford
2025, Diversity and Distributions (31)
AimWhite-nose syndrome has caused severe declines in eastern North American cave bats, leading to the federal listing of the northern long-eared bat (Myotis septentrionalis) as endangered in the United States and Canada. This has heightened the importance of long-term monitoring to inform species status assessments. We employed a combination of...

Groundwater structures fish growth and production across a riverscape
Jeffrey R. Baldock, Robert Al-Chokhachy, Annika W. Walters
2025, Freshwater Biology (70)
Landscapes are composed of habitat patches and conditions that vary across space and time. While habitat variability and complexity can support important ecological processes and ecosystem services, the dynamic nature of habitats can also constrain organismal growth and production as optimal conditions are fleeting. In riverine ecosystems, groundwater discharge...
When do single-species occupancy models outperform multispecies models?
Gavin G. Cotterill, Douglas A. Keinath, Tabitha A. Graves
2025, Ecology and Evolution (15)
Occupancy models have become increasingly popular for species monitoring and assessment, in part, because detection/non-detection data are readily obtained using a variety of methods. Multispecies occupancy models (MSOMs) can yield more accurate parameter estimates than single-species models (SSOMs) with less data through their hierarchical structure, making MSOMs an attractive option...
Topographic, climatic, and age controls on the reworking of volcanic debris avalanche deposits
Kristin Sweeney, Jon J. Major

Bradley J. Butterfield, Daniel Rodolphe Schlaepfer, Robert Al-Chokhachy, Jason Dunham, Jeremiah D. Groom, Clint C. Muhlfeld, Christian E. Torgersen, John B. Bradford
2025, Ecosphere (16)
Landscapes encompass both aquatic and terrestrial ecosystems that experience the same climate but may respond to climate in divergent ways. For example, the time lag between seasonal dry-down of terrestrial soil moisture and decline in streamflow has important implications for species and ecosystem processes across the aquatic–terrestrial interface. How these...
