Predicting future mangrove forest migration in the Everglades under rising sea level
Mangroves are highly productive ecosystems that provide valued habitat for fish and shorebirds. Mangrove forests are universally composed of relatively few tree species and a single overstory strata. Three species of true mangroves are common to intertidal zones of the Caribbean and Gulf of Mexico Coast, namely, black mangrove (Avicennia germinans), white mangrove (Laguncularia racemosa), and red

Effects of hydrology on red mangrove recruits
Coastal wetlands along the Gulf of Mexico have been experiencing significant shifts in hydrology and salinity levels over the past century as a result of changes in sea level and freshwater drainage patterns. Local land management in coastal zones has also impacted the hydrologic regimes of salt marshes and mangrove areas. Parks and refuges in south Florida that contain mangrove forests have, in s

Pallid sturgeon in the Lower Mississippi Region: Hematology and genome information
This project (Project 1448-43270-2M-002) has been coordinated through the Natchitoches National Fish Hatchery (NNFH) and the U.S. Geological Survey’s National Wetlands Research Center (NWRC). From November 2001 to April 2002, over 280 sturgeon of the genus Scaphirhynchus (including pallid sturgeon, shovelnose, and their hybrids) were sampled from the outflow channel of the Old River Control Struct

Native plants for effective coastal wetland restoration
Plant communities, along with soils and appropriate water regimes, are essential components of healthy wetland systems. In Louisiana, the loss of wetland habitat continues to be an issue of major concern. Wetland loss is caused by several interacting factors, both natural and human-induced (e.g., erosion and saltwater intrusion from the construction of canals and levees). Recent estimates of annua

Lost and found: Louisiana’s coastal prairies
It’s hard to fathom, but in just 250 years, some 2.5 million acres of coastal prairie that once blanketed in southwest Louisiana have dwindled to just 200 in scattered parcels.The journals of early settlers give us a peek at what it was like: “plentiful game,” “seemingly infinite range for livestock forage,” “long growing season.” As the human population grew, with its concomitant increase in trad

Lower survival probabilities for adult Florida manatees in years with intense coastal storms
The endangered Florida manatee (Trichechus manatus latirostris) inhabits the subtropical waters of the southeastern United States, where hurricanes are a regular occurrence. Using mark-resighting statistical models, we analyzed 19 years of photo-identification data and detected significant annual variation in adult survival for a subpopulation in northwest Florida where human impact is low. That v
