Floodplain forest tree seedling response to variation in flood timing and duration
W.A. Kroschel, Sammy L. King
2021, Forest Ecology and Management (502)
The regeneration process is a sensitive period within life cycles of floodplain tree species and can strongly influence forest community composition. Yet, fundamental information remains limited on the relationship between regeneration processes and the flood disturbances that, together, construct floodplain forest landscapes. In a controlled greenhouse experiment we tested the effects of complete submergence on six...

Invasive species surveillance programs can utilize environmental DNA sampling and analysis to provide information on the presence of invasive species. Wider utilization of eDNA techniques for invasive species surveillance may be warranted. This paper covers topics directed towards invasive species managers and eDNA practitioners working at the intersection of eDNA...
Fire refugia in old-growth forests: Predicting habitat persistence to support land management in an era of rapid global change
Cameron E. Naficy, Garrett W. Meigs, Matt J. Gregory, Ray Davis, David M. Bell, Katie Dugger, J. David Wiens, Meg A. Krawchuk
2021, Report
Recent stand-replacing wildfires in late-successional and old-growth (LSOG) forests have increased land manager interest in fire refugia, which could provide vital habitat for threatened and endangered species during a time of rapid change. The overall goal of this project was to model, map, and share information essential for the conservation...
Optical properties of water for prediction of wastewater contamination, human-associated bacteria, and fecal indicator bacteria in surface water at three watershed scales
Steven R. Corsi, Laura A. DeCicco, Angela Hansen, Peter L. Lenaker, Brian A. Bergamaschi, Brian A. Pellerin, Debra Dila, Melinda Bootsma, Susan Spencer, Mark A. Borchardt, Sandra L. McLellan
2021, Environmental Science and Technology (55) 13770-13782
Relations between spectral absorbance and fluorescence properties of water and human-associated and fecal indicator bacteria were developed for facilitating field sensor applications to estimate wastewater contamination in waterways. Leaking wastewater conveyance infrastructure commonly contaminates receiving waters. Methods to quantify such contamination can be time consuming, expensive, and often nonspecific. Human-associated...

Sarai Acosta, Todd Kelman, Shane Feirer, Elliott Matchett, Jaclyn A. Smolinsky, Maurice E. Pitesky, Jeffrey J. Buler
2021, Avian Diseases (65) 483-492
Migratory waterfowl are the primary reservoir of avian influenza viruses (AIV) which can be spread to commercial poultry. Surveillance efforts that track the location and abundance of wild waterfowl and link those data to inform assessments of risk and sampling for AIV currently do not exist. To assist surveillance and...

Kimberly Miner, Rachel Mackelprang, Juliana D’Andrilli, Arwyn Edwards, Michael J. Malaska, Mark P. Waldrop, Charles E. Miller
2021, Nature Climate Change (11) 809-819
The Arctic cryosphere is collapsing, posing overlapping environmental risks. In particular, thawing permafrost threatens to release biological, chemical and radioactive materials that have been sequestered for tens to hundreds of thousands of years. As these constituents re-enter the environment, they have the potential to disrupt ecosystem...
Invasion frustration: Can biotic resistance explain the small geographic range of non-native croaking gourami Trichopsis vittata (Cuvier, 1831) in Florida, USA?
Pam Schofield, Quenton M. Tuckett, Daniel Slone, Kristen Reaver, Jeffrey H. Hill
2021, Aquatic Invasions (16) 512-526
Croaking gourami Trichopsis vittata is a non-native fish species that has maintained a reproducing population in Florida, USA, since at least the 1970s. However, unlike most other non-native fishes in Florida, T. vittata has not spread beyond its very small (ca. 5 km²) range. We suspected the inability of T....

David C. Kazyak, E. M. Hallerman, Lori Maloney, Stephen Faulkner, Amy Welsh, Jason Coombs, Andrew Whiteley, Jake Rash, Shannon L. White, Meredith L. Bartron, Matt A. Kulp, Mariah Meek
2021, Report
Traditionally, fisheries management has focused on the abundance, distribution, and size structure of populations. Although these factors remain key aspects of management, a large and growing body of evidence highlights the importance of genetics in conserving wild populations, especially when populations are small and isolated (Frankham et al. 2017). Local...
Effect of an algal amendment on the microbial conversion of coal to methane at different sulfate concentrations from the Powder River Basin, USA
Heidi J. Smith, Hannah S. Schweitzer, Elliott Barnhart, William H. Orem, Robin Gerlach, Matthew W. Fields
2021, International Journal of Coal Geology (248)
Biogenic methane is estimated to account for one-fifth of the natural gas worldwide and there is great interest in controlling methane from different sources. Biogenic coalbed methane (CBM) production relies on syntrophic associations between fermentative bacteria and methanogenic archaea to anaerobically degrade recalcitrant coal and produce methanogenic substrates. However, very...
