Coastal Louisiana wetlands make up the seventh largest delta on Earth and support the largest commercial fishery in the lower 48 states. However, Louisiana currently undergoes ~90% of the total coastal wetland loss in the continental U.S.Learn more
Genetics and tracking helps USGS researchers learn where the invasive fish are now – and where they may go next.
Researchers from the U.S. Geological Survey and Louisiana State University have identified a new genus and species of cavefish from Mexico, the Oaxaca Cave Sleeper, which is the first cave-adapted sleeper goby to be found in the Western Hemisphere.
A special edition of the journal Ecological Modelling has been dedicated to Donald DeAngelis, U.S. Geological Survey Research Ecologist, in honor of his 70th birthday. A a prominent contributor to the journal, DeAngelis has played a decisive role in the progression of ecological and mathematical modeling, specifically related to individual-based approaches.
The most recent revision of the North American Waterfowl Management Plan seeks to increase the adaptive capacity of the management enterprise to cope with accelerating changes in climate, land-use patterns, agency priorities, and the waterfowl and wetlands constituency. Institutional and cultural changes of the magnitude envisioned are necessarily slow, messy processes, involving many actors who...Read More
Tidal marsh creation helps remediate global warming because tidal wetlands are especially proficient at sequestering carbon (C) in soils. However, greenhouse gas (GHG) losses can offset the climatic benefits gained from C storage depending on how these tidal marshes are constructed and managed. This study attempts to determine the GHG emissions from a 4–6 year old created brackish marsh, what...Read More
Adjustment of hunting season length is often used to regulate harvest of waterbirds but the effects are disputed. We describe the first results of season length extension on the harvest of the pink-footed goose, which has been selected as the first test case of adaptive harvest management of waterbirds in Europe. In Denmark, the season (previously 1 September to 31 December) was extended to...Read More
