Multi-species duck harvesting using dynamic programming and multi-criteria decision analysis
1.Multiple species are often exposed to a common hunting season, but harvest and population objectives may not be fully achieved if harvest potential varies among species and/or species abundances are not correlated through time. Our goal was to develop an approach for setting a common hunting season that would recognize heterogeneity in species...
Johnson, Fred; Zimmerman, Guthrie S.; Huang, Min; Padding, Paul I.; Balkcom, Greg; Runge, Michael; Devers, Patrick K. Mississippi river sediment diversions and coastal wetland sustainability: Synthesis of responses to freshwater, sediment, and nutrient inputs
Management and restoration of coastal wetlands require insight into how inundation, salinity, and the availability of mineral sediment and nutrients interact to influence ecosystem functions that control sustainability. The Mississippi River Delta, which ranks among the world's largest and most productive coastal wetland complexes, has experienced...
Elsey-Quirk, Tracy; Graham, Sean A.; Mendelssohn, Irving A.; Snedden, Gregg; Day, John W.; Shaffer, Gary P.; Sharp, Leigh Anne; Twilley, Robert R.; Pahl, James; Lane, R.R. Resource concentration mechanisms facilitate foraging success in simulations of a pulsed oligotrophic wetland
ContextMovement of prey on hydrologically pulsed, spatially heterogeneous wetlands can result in transient, high prey concentrations, when changes in landscape features such as connectivity between flooded areas alternately facilitate and impede prey movement. Predators track and exploit these concentrations, depleting them as they arise....
Yurek, Simeon; DeAngelis, Donald L. Invasive plant species
Invasive species may be one of the worts environmental problems facing the conservation of natural areas, because of their role in changing ecosystem function. At the same time, invasive species cause much human suffering and economic loss. The approach to eliminating invasive species can be improved by a better understanding of the...

Flood-inundation maps for Lake Champlain in Vermont and New York
In 2016, digital flood-inundation maps along the shoreline of Lake Champlain in Addison, Chittenden, Franklin, and Grand Isle Counties in Vermont and northern Clinton County in New York were created by the U.S. Geological Survey (USGS) in cooperation with the International Joint Commission (IJC). This report discusses the creation of updated...
Flynn, Robert H.; Hayes, Laura Coastal habitat change and marine megafauna behavior: Florida manatees encountering reduced food provisions in a prominent winter refuge
A decline in submerged aquatic vegetation (SAV) within Florida’s spring-fed thermal refuges raises questions about how these systems support winter foraging of Florida manatees Trichechus manatus latirostris. We analyzed telemetry data for 12 manatees over 7 yr to assess their use of Kings Bay, a winter refuge with diminished SAV. After...
Littles, Chanda J.; Bonde, Robert K.; Butler, Susan M.; Jacoby, Charles A.; Notestein, Sky K.; Reid, James P.; Slone, Daniel H.; Frazer, Thomas K. The plant diversity sampling design for The National Ecological Observatory Network
The National Ecological Observatory Network (NEON) is designed to facilitate an understanding of the impact of environmental change on ecological systems. Observations of plant diversity—responsive to changes in climate, disturbance, and land use, and ecologically linked to soil, biogeochemistry, and organisms—result in NEON data products that...

The status of the American crocodile (Crocodylus acutus) has long been a matter of concern in Everglades National Park (ENP) due to its classification as a federal and state listed species, its recognition as a flagship species, and its function as an ecosystem indicator. Survival and recovery of American crocodiles has been linked with regional...
Mazzotti, Frank J.; Smith, Brian; Squires, Michiko; Cherkiss, Michael S.; Farris, Seth C; Hackett, Caitlin; Hart, Kristen M.; Briggs-Gonzalez, Venetia; Brandt, Laura A. Microclimate influences mangrove freeze damage: Implications for range expansion in response to changing macroclimate
In response to warming winter air temperatures, freeze-sensitive mangrove forests are expected to expand at the expense of freeze-tolerant salt marshes. To better anticipate and prepare for mangrove range expansion, there is a need to advance understanding of the modulating role of microclimate. Here, we synthesized hypotheses regarding the...
Osland, Michael J.; Hartmann, Arik M.; Day, Richard H.; Ross, Michael S.; Hall, Courtney T.; Feher, Laura C.; Vervaeke, William Deep search: Deep sea exploration to advance research on coral/canyon/cold seep habitats
Led by the Bureau of Ocean Energy Management (BOEM), the United States Geological Survey (USGS), and OER is an interagency partnership to explore and characterize sensitive deepwater habitats of the U.S. mid- and south Atlantic deep-sea habitats. Sponsored by the National Oceanographic Partnership Program, the study has brought together scientists...
Cordes, Erik E.; Demopoulos, Amanda W.J.; Rasser, Michael; Adams, Caitlin Adapting a regional water-quality model for local application: A case study for Tennessee, USA
We evaluated whether SPAtially Referenced Regression On Watershed attributes (SPARROW) models calibrated for two adjacent USA regions could be applied at the local scale to support management decisions for streams in Tennessee. Nutrient-source apportionment of load is important for this local-scale application and demands careful...
Hoos, Anne B.; Wang, Sherry H.; Schwarz, Gregory E. Modeling δ18O as an early indicator of regime shift arising from salinity stress in coastal vegetation
In many important coastal habitats, a combination of increasing soil salinization due to sea level rise, reduced precipitation and storm surges may induce regime shift from salinity-intolerant glycophytic vegetation to salinity-tolerant halophytic species. Early detection of regime shift due to salinity stress in vegetation may facilitate...

America’s rivers and streams are generally suitable for irrigation, supplying drinking water, and home and recreational uses. However, in areas with significant agricultural and urban development, the quality of our nation’s water resources has been degraded by contaminants such as pesticides, nutrients, and gasoline-related compounds.
A new map from the U.S. Geological Survey and the Central United States Earthquake Consortium shows that Central States, including Arkansas, Tennessee, Missouri, Kentucky and Indiana are among the most seismically active states east of the Rocky Mountains. More than 800 earthquakes are cataloged on the map that depicts the locations of earthquakes large enough to be felt, since 1699.

Wildfires have long played a key role in structuring ecosystems and plant communities in the southeastern United States. From the coastal prairie of Texas and Louisiana to the marshes and pinelands of Florida, many native species have adapted to a natural regime of frequent wildfire caused by lightning strikes.
