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
Florida’s iconic manatee population is highly likely to endure for the next 100 years, so long as wildlife managers continue to protect the marine mammals and their habitat, a new study by the US Geological Survey and the Florida Fish and Wildlife Research Institute has found.

The Fish Slam event discovered two nonnative fish species never seen before in Big Cypress National Preserve.
Ecological regime shift drives declining growth rates of sea turtles throughout the West Atlantic
Somatic growth is an integrated, individual-based response to environmental conditions, especially in ectotherms. Growth dynamics of large, mobile animals are particularly useful as bio-indicators of environmental change at regional scales. We assembled growth rate data from throughout the West Atlantic for green turtles, Chelonia mydas, which are long-lived, highly migratory, primarily...
Created mangrove wetlands store belowground carbon and surface elevation change enables them to adjust to sea-level rise
Mangrove wetlands provide ecosystem services for millions of people, most prominently by providing storm protection, food and fodder. Mangrove wetlands are also valuable ecosystems for promoting carbon (C) sequestration and storage. However, loss of mangrove wetlands and these ecosystem services are a global concern, prompting the restoration and creation of mangrove wetlands as a potential...
Modeling the long-term effects of introduced herbivores on the spread of an invasive tree
ContextMelaleuca quinquenervia (Cav.) Blake (hereafter melaleuca) is an invasive tree from Australia that has spread over the freshwater ecosystems of southern Florida, displacing native vegetation, thus threatening native biodiversity.
