2023, Frontiers in Microbiology (14)
The addition of small amounts of algal biomass to stimulate methane production in coal seams is a promising low carbon renewable coalbed methane enhancement technique. However, little is known about how the addition of algal biomass amendment affects methane production from coals of different thermal maturity. Here, we show...
Nest traits and major flooding events influence nest survival of Emperor Geese while regional environmental variation linked to climate does not
Jordan M. Thompson, Brian D. Uher-Koch, Bryan L. Daniels, Joel A. Schmutz, Benjamin S. Sedinger
2023, Ornithological Applications (125)
The reproductive ecology of geese that breed in the Arctic and subarctic is likely susceptible to the effects of climate change, which is projected to alter the environmental conditions of northern latitudes. Nest survival is an important component of productivity in geese; however, the effects of regional environmental conditions...

Kaycee E. Faunce, Larry B. Barber, Steffanie H. Keefe, Jeramy Roland Jasmann, Jennifer L. Krstolic
2023, Journal of the American Water Resources Association (59) 779-802
A wastewater model was applied to the Potomac River watershed to provide (i) a means to identify streams with a high likelihood of carrying elevated effluent-derived contaminants and (ii) risk assessments to aquatic life and drinking water. The model linked effluent discharges along stream networks, accumulated...

Barry P. Baldigo, Scott D. George, Andrew Lenox, Mark Filipski, Brian T. Duffy
2023, Journal of Great Lakes Research (49) 463-478
Anthropogenically degraded benthic-macroinvertebrate communities (benthos) are one of seven beneficial use impairments (BUIs) in the Niagara River Area of Concern (AOC). Over the last 50 years, upgrades to waste-water treatment, industry closures, and sediment remediations reduced contaminant levels throughout the system. Improvements...
Evaluating brook trout egg and alevin survival at different temperatures in simulated karst environments with marl sedimentation
John. Davidson, Clayton D. Raines, Curtis Crouse, CHristopher Goodchild, Brandon J. Keplinger
2023, Journal of the Southeastern Association of Fish and Wildlife Agencies (10) 27-35
Brook trout (Salvelinus fontinalis) have been extirpated from many karst-geology streams in West Virginia; however, the causes are not fully understood. Specifically, the impact of calcareous precipitate (marl), which is common in hard-water environments, has not been evaluated as an im- pediment to juvenile survival. Accordingly, two...

We identified a total of 19 taxonomic groups of...
Food caching by a solitary large carnivore reveals importance of intermediate-sized prey
Maximilian L. Allen, L. Mark Elbroch, Javan Mathias Bauder, Heiko U. Wittmer
2023, Journal of Mammalogy (104) 457-165
Pumas (Puma concolor) are solitary large carnivores that exhibit high energetic investments while hunting prey that often take multiple days to consume. Therefore, pumas should behave in a way to maximize their energetic gains, including using caching, which is a behavior used by many mammal species to preserve and store...

2023, Frontiers in Ecology and Evolution (11)
With viruses often having devastating effects on wildlife population fitness and wild mammals serving as pathogen reservoirs for potentially zoonotic diseases, determining the viral diversity present in wild mammals is both a conservation and One Health priority. Additionally, transmission from more abundant hosts could increase the extinction risk of...

Sarah Russell, Lisamarie Windham-Myers, Ellen J Goodrich-Stuart, Brian A. Bergamaschi, Frank Anderson, Patty Oikawa, Sara Knox
2023, Environmental Research Letters (18)
Tidal marshes sequester 11.4–87.0 Tg C yr−1 globally, but climate change impacts can threaten the carbon capture potential of these ecosystems. Tidal marshes occur across a wide range of salinity, with brackish marshes (0.5–18 ppt (parts per thousand)) dominating global tidal marsh extents. A diverse mix of freshwater-...

2023, Scientific Investigations Report 2023-5016
Introduction During April through September 2022, much of New England experienced a short but extreme hydrologic drought that was similar to the drought of 2020. By August 2022, Providence, Rhode Island, was declared a Federal disaster area, and New London and Windham counties in Connecticut were declared natural disaster areas. Mandatory...
Movement ecology of diploid and triploid grass carp in a large reservoir and upstream tributaries
Tyler Michael Hessler, Duane Chapman, Craig P. Paukert, Jeff C. Jolley, Michael E. Byrne
2023, PLoS ONE (18)
Grass carp Ctenopharyngodon idella, is an herbivorous fish originally brought to North America from Asia in 1963 to control nuisance aquatic vegetation. Since their arrival, detrimental alterations to aquatic ecosystems have sometimes occurred in waterways where they were initially stocked and into which they have escaped. The...

Marc L. Buursink, Steven T. Anderson, Sean T. Brennan, Erick R. Burns, Philip A. Freeman, Joao S. Gallotti, Celeste D. Lohr, Matthew D. Merrill, Eric A. Morrissey, Michelle R. Plampin, Peter D. Warwick
2023, Fact Sheet 2022-3082
Introduction As the United States transitions away from fossil fuels, its economy will rely on more renewable energy. Because current renewable energy sources sometimes produce variable power supplies, it is important to store energy for use when power supply drops below power demand. Battery storage is one method to store power....
