Charles J. Pell, Sammy L. King, Tracy S. Hawkins, Matt Symmank
2025, Forest Ecology and Management (577)
Globally, floodplain forests are experiencing shifts in species composition associated with drier conditions and disruptions of flood pulse hydrology. The specific processes behind these shifts in composition are not fully understood, but differential effects of drought on regeneration processes such as seed germination may be partially responsible. To determine how...

Over the past few decades, Ictalurus furcatus (Valenciennes in Cuvier and Valenciennes, 1840; blue catfish) have become a formidable invasive species in tidal tributaries of the Chesapeake Bay in Maryland and Delaware. Knowledge of their reproductive behaviors can support managers in the determination of ideal timing and implementation of mitigation...
National seed strategy for rehabilitation and restoration progress report 2022 & 2023: Handout
Laura Cecilia Shriver, Claudia Mengelt
2025, Report
Restoring healthy, resilient, biodiverse ecosystems is crucial for our Nation’s future. Native plant communities provide essential environmental benefits, such as buffering against extreme weather, improving air, soil, and water quality, and habitat for wildlife. However, the limited availability of locally adapted native plants hampers effective ecological restoration. To address this...

Joel T. Groten, J. William Lund, Erin N. Coenen, Andrea Medenblik, Harper N. Wavra, Mike Kennedy, Gregory D. Johnson
2025, Fact Sheet 2025-3005
A thorough understanding of fluvial sediment transport is essential for addressing key environmental issues such as aquatic habitat degradation, flooding, excess nutrients, and challenges with river restoration. Fluvial sediment samples are valuable for addressing these concerns, but their collection is often impractical across all rivers and timeframes of interest. In...

David M. Rey, Martin A. Briggs, Andrea K. Tokranov, Hayley Gale Lind, Patrick Thomas Scordato, Ramona Iery, Henry Moore, L. Slater, Denis R. LeBlanc
2025, Science of the Total Environment (964)
Groundwater-dependent ecosystems in areas with industrial land use are at risk of exposure to a PFAS chemicals. We investigated one such system with several known PFAS source areas, where high and low permeability sediments (glacial) coupled with groundwater-lake and groundwater/surface-water interactions created complex ‘source to seep’ dynamics. Using heat-tracing and...

Lake Superior is the least anthropogenically impacted of the Laurentian Great Lakes ecosystems, yet dramatic changes to the fish community are evident. Previous published works chronicled those changes and the efforts to rehabilitate the fish community through the year 2000. Here, we review through the year 2022, where post-rehabilitation stability was driven...
