Spatial ecology of invasive Burmese pythons in southwestern Florida
Ian A. Bartoszek, Brian J. Smith, Robert Reed, Kristen Hart
2021, Ecosphere (12)
Understanding the spatial ecology of an invasive species is critical for designing effective control programs. Determining and quantifying home range estimates and habitat associations can streamline targeted removal efforts for wide-ranging, cryptic animals. The Burmese python (Python bivittatus) is a large-bodied constrictor snake with an established and expanding invasive population...

Brandon T. Anderson
2021, Scientific Investigations Report 2021-5046
Annual exceedance probability flows at gaged locations and regional regression equations used to estimate annual exceedance probability flows at ungaged locations were developed by the U.S. Geological Survey, in cooperation with the Mississippi Department of Transportation, to improve flood-frequency estimates at rural streams in the alluvial plain of the lower...
Trophic niches of native and nonnative fishes along a river-reservoir continuum
Casey A. Pennock, Zachary T. Ahrens, Mark McKinstry, Phaedra E. Budy, Keith B. Gido
2021, Scientific Reports (11) 1-12
Instream barriers can constrain dispersal of nonnative fishes, creating opportunities to test their impact on native communities above and below these barriers. Deposition of sediments in a river inflow to Lake Powell, USA resulted in creation of a large waterfall prohibiting upstream movement of fishes from the reservoir allowing us...

Kristin L. Jaeger, Konrad Hafen, Jason B. Dunham, Ken M. Fritz, Stephanie K. Kampf, Theodore B. Barnhart, Kendra E. Kaiser, Roy Sando, Sherri L Johnson, Ryan R. McShane, Sarah Beth Dunn
2021, Water (12)
Observations of the presence or absence of surface water in streams are useful for characterizing streamflow permanence, which includes the frequency, duration, and spatial extent of surface flow in streams and rivers. Such data are particularly valuable for headwater streams, which comprise the vast majority of channel length in stream...
Integrated hydrology and operations modeling to evaluate climate change impacts in an agricultural valley irrigated with snowmelt runoff
Wesley Kitlasten, Eric D. Morway, Richard G. Niswonger, Murphy Gardner, Jeremy T. White, Enrique Triana, David J. Selkowitz
2021, Water Resources Research (57)
Applying models to developed agricultural regions remains a difficult problem because there are no existing modeling codes that represent both the complex physics of the hydrology and anthropogenic manipulations to water distribution and consumption. We apply an integrated groundwater – surface water and hydrologic river operations model...
A review of osmoregulation in lamprey
Diogo Ferreira-Martins, Jonathan M Wilson, Scott P Kelly, Dennis Kolosov, Stephen D. McCormick
2021, Journal of Great Lakes Research (47) S59-S71
Lamprey are living representatives of the basal vertebrate agnathan lineage. Many lamprey species are anadromous with a complex life cycle that includes metamorphosis from a freshwater (FW) benthic filter-feeding larva into a parasitic juvenile which migrates to seawater (SW) or (in landlocked populations) large bodies of FW. After a juvenile/adult...

Rebecca M. Kreiling, Lynn A. Bartsch, Patrik Mathis Perner, Enrika Hlavacek, Victoria Christensen
2021, Environmental Management (68) 279-293
Watershed land cover affects in-stream water quality and sediment nutrient dynamics. The presence of natural land cover in the riparian zone can reduce the negative effects of agricultural land use on water quality; however, literature evaluating the effects of natural riparian land cover on stream sediment nutrient dynamics is scarce....

Corbin D. Hilling, Jason L. Fischer, Jason E. Ross, Taaja Tucker, Robin L. DeBruyne, Christine M. Mayer, Edward F. Roseman
2021, Water (12)
Shallow water riparian zones of large rivers provide important habitat for fishes, but anthropogenic influences have reduced the availability and quality of these habitats. In the St. Clair–Detroit River System, a Laurentian Great Lakes connecting channel, losses of riparian habitat contributed to impairment of fish populations and their habitats. We...

J. Patrick Donnelly, Sammy L. King, Jeff Knetter, James H. Gammonley, Victoria J. Dreitz, Blake A. Grisham, M. Cathy Nowak, Daniel P. Collins
2021, Ecosphere (12)
Preserving avian flyway connectivity has long been challenged by our capacity to meaningfully quantify continental habitat dynamics and bird movements at temporal and spatial scales underlying long-distance migrations. Waterbirds migrating hundreds or thousands of kilometers depend on networks of wetland stopover sites to rest and refuel. Entire populations may rely...

Angela K. Fuller, Joshua C. Stiller, William F. Siemer, Kelly A. Perkins
2021, Book chapter, Harvest of fish and wildlife: New paradigms for sustainable management
Waterfowl hunters have an important economic impact on local, state, and national economies, and are important stakeholders in decisions regarding waterfowl harvest season dates. Individual states are responsible for annually setting duck season dates that conform to the migratory game bird season frameworks as set by the U.S. Fish and...
Harvest as a tool to manage populations of undesirable or overabundant fish and wildlife
Craig P. Paukert, Elisabeth B. Webb, Drew N. Fowler, Corbin D. Hilling
2021, Book chapter, Harvest of fish and wildlife: New paradigms for sustainable management
Harvest is a common management tool for fish and game species and can also be used for overabundant populations when stakeholders want to reduce populations reduced and still provide recreational opportunities. The authors propose a framework to determine if harvest can be used to control populations when overabundance is an...

Hayley T. Olds, Steven R. Corsi, Troy D. Rutter
2021, Integrated Environmental Assessment and Management (18) 245-257
A comparison of the presence of additives in airport deicers commonly used in the United States and in airport runoff was conducted with data collected before and after changes in deicer formulations. Three isomers of benzotriazoles (BTs)—4-methyl-1H-benzotriazole (4-MeBT), 5-methyl-1H-benzotriazole (5-MeBT), and 1H-benzotriazole (1H-BT)—are corrosion inhibitors added to some formulations of...
