Autonomous recording units (ARUs) are an emerging technology that allows for passive monitoring of soniferous animals and soundscapes. Over the past decade, ARUs have become a popular tool for monitoring birds for their potential to reduce the labor and costs of traditional in-person sampling procedures. However, uncertainty surrounding factors affecting...

Light regulates the vertical migration of many aquatic organisms. Mysis species couple pelagic and benthic habitats in lakes by diel vertical migrations (DVM), transporting energy and nutrients through the water column and food web. Although Mysis are generally assumed to remain on the bottom during the day, some have been observed in the pelagic...
Evaluating effectiveness of flocculation and wave-reduction barriers for restoration of a turbid, terminal lake
Cassandra Smith, Randy Joe Brannan
2025, Wetlands Ecology and Management (33)
Malheur Lake is a freshwater, shallow lake that provides key habitat for birds along the Pacific Flyway in North America. The lake shifted to a turbid state in the 1990s with suspended-sediment concentrations sometimes exceeding 1000 mg/L and minimal light available in the water column for submerged aquatic vegetation. Resource...
Non-native prey availability and over-compensatory density dependence drive population dynamics of a native fish predator
Madaline Cochrane, Timothy Cline, Travis S. Schmidt, James Dunnigan, Will Warnock, Clint C. Muhlfeld
2025, Ecological Applications (35)
Understanding the factors that regulate population dynamics is crucial for conserving imperiled species. Bull trout (Salvelinus confluentus), a piscivorous salmonid and one of North America's most threatened cold-water species, has declined significantly due to habitat loss, overfishing, invasive species, and climate change. While recovery efforts have primarily targeted these threats,...
Host responses and viral traits interact to shape the impacts of climate warming on highly pathogenic avian influenza in migratory waterfowl
Claire Stewart Teitelbaum, Michael L. Casazza, Cory T. Overton, Elliott Matchett, Diann Prosser
2025, PLOS Computational Biology. (21)
Emerging infectious diseases pose threats to wildlife populations, as exemplified by recent outbreaks of avian influenza viruses in wild birds. Climate change can affect infection dynamics in wildlife through direct effects on pathogens (e.g., environmental decay rates) and changes to host ecology, including shifting migration patterns. Here, we adapt an...

Evan M. Bredeweg, Ivan Arismendi, Christina Amy Murphy, Sarah K. Henkel
2025, Limnologica - Ecology and Management of Inland Waters (115)
Floating photovoltaic (FPV) systems are emerging as a promising strategy for large-scale clean energy production worldwide. However, by altering key physical drivers such as solar radiation and wind mixing, FPV installations may have also unintended consequences for lakes and reservoirs. Given the wide diversity of freshwater systems globally, understanding the...
Submarine groundwater discharge creates cold‐water refugia that can mitigate exposure of heat stress in nearshore corals
Eric E. Grossman, Ferdinand K.J. Oberle, Curt D. Storlazzi
2025, Frontiers in Marine Science (12)
Coral reef mortality around the world is accelerating due to human activities and rising sea temperatures that cause bleaching, which is expected to become more frequent. Our ability to predict which corals will be most resilient, however, remains limited due to insufficient information characterizing nearshore temperature and habitat conditions. In...

2025, Hydological Processes (39)
In urban areas, floodplain restoration is gaining prominence as a strategy for restoring the natural functions of floodplain ecosystems and reducing flood risk. This has spurred research into potential interactions between floodwaters, the hyporheic zone, and the floodplain aquifer. An urban restored stream in Wisconsin, USA, was used as a...

Animal movement influences local transmission and geographic spread of pathogens. Waterfowl are known reservoirs of pathogens, including H5 goose/Guangdong lineage (H5 GsGd) highly pathogenic avian influenza (HPAI). This HPAI virus lineage causes high rates of morbidity and mortality in domestic poultry and many wild bird species. Mallards (Anas platyrhynchos) are...
A systematic literature review of forecasting and predictive models of harmful algal blooms in flowing waters
Jennifer C. Murphy, Rebecca Michelle Gorney, Lisa Lucas, Jacob Aaron Zwart, Jennifer L. Graham
2025, Preprint
Occurrences of harmful algal blooms (HABs) in rivers challenge the belief that rivers are not susceptible to HABs because of their short residence times and fluctuating hydrology. Here we present a systematic literature review of predictive and forecasting models for HABs in flowing waters, including rivers, flowing in-stream reservoirs (e.g.,...

Angus Vaughan, Faith Fitzpatrick, Jayme M. Strange, Molly Van Appledorn
2025, Completion Report 2021HG7
In 2020 the U.S. Geological Survey (USGS), as part of the Upper Mississippi River Restoration (UMRR) Program, began a new project to characterize potential hydrogeomorphic change associated with hydrogeomorphic units (HGUs) and their catenae (units linked by their association with sediment sources and flow origins). The goal of the project...
Triple-oxygen isotopic evidence of prolonged direct bioleaching of pyrite with O2
Issaku Kohl, Bryan Alan Killingsworth, Karen Zeigler, Edward D. Young, Max Coleman
2025, Earth and Planetary Science Letters (671)
Sulfate is often touted as containing atmospheric oxygen whose isotopic signature can constrain redox, environmental conditions, and biological activity. Yet, the amount and isotopic fractionation associated with air-O2 incorporation during sulfate formation is still debated, making its verification difficult. In this study, we identify a distinct, microbially dominated environment with the...
