Wind shear stress measurements in a coastal marsh during Hurricane Andrew Wind shear stress measurements in a coastal marsh during Hurricane Andrew
Hurricane Andrew produced changes to the Louisiana wetlands not normally observed after lesser, more common storms. For example, the

Structural impact of hurricane Andrew on the forested wetlands of the Atchaflaya Basin in South Louisiana Structural impact of hurricane Andrew on the forested wetlands of the Atchaflaya Basin in South Louisiana
On August 26, 1992, Hurricane Andrew hit the Louisiana coast and traversed a large portion of the lower Atchafalaya Basin, bounding the largest remaining tract of cypress-tupelo and bottomland hardwood swamp in the United States. Permanent field sites were established following the hurricane to assess the extent of forest damage and to monitor the rate and process of forest recovery...

Comparison of condition indices in migratory passerines at a stopover site in coastal Louisiana Comparison of condition indices in migratory passerines at a stopover site in coastal Louisiana
We evaluated the utility of four nondestructive condition indices—body mass, body mass scaled by wing chord length, fat scoring, and total body electrical conductivity method (TOBEC)—as predictors of lipid levels in migrating Wood Thrushes (Hylocichla mustelina), Swainson's Thrushes (Catharus ustulatus), and Summer Tanagers (Piranga rubra). The Red-winged Blackbird (Agelaius phoeniceus)...

Effect of increased water depth on growth of a common perennial freshwater-intermediate marsh species in Coastal Louisiana Effect of increased water depth on growth of a common perennial freshwater-intermediate marsh species in Coastal Louisiana
The response of Sagittaria lancifolia to increased water depths of 7.5 and 15 cm was examined in this field study. Water-depth treatments were achieved by digging sods containing one or two individual plants or ramets of S. lancifolia from the marsh, removing sediment from the resulting hole, and replacing the sods in their original location at the appropriate lower elevation. Plants...

Species-specific patterns of hyperostosis in marine teleost fishes Species-specific patterns of hyperostosis in marine teleost fishes
The occurrence of swollen or hyperostotic bones in skeletal preparations, preserved museum material or whole fresh specimens of marine teleost fishes was identified in 92 species belonging to 22 families. Patterns of hyperostotic skeletal growth were typically consistent and often species-specific in all individuals larger than a certain size. The taxonomic distribution of hyperostosis...

Survey for blood parasites in redheads (Aythya americana) wintering at the Chandeleur Islands, Louisiana Survey for blood parasites in redheads (Aythya americana) wintering at the Chandeleur Islands, Louisiana
We detected no infections with species of Plasmodium, Haemoproteus, Leucocytozoon, Sarcocystis or Trypanosoma in blood smears, liver and spleen impressions, and muscle tissue from 136 redheads (Aythya americana) collected or captured at the Chandeleur Islands, Louisiana (USA), during three winters (1987 to 1990). One bird, a juvenile male, was infected with an unidentified species of...

Seagrass distribution in the Northern Gulf of Mexico Seagrass distribution in the Northern Gulf of Mexico
Seagrass ecosystems are widely recognized as some of the most productive benthic habitats in estuarine and nearshore waters of the gulf coast. Seagrass meadows provide food for wintering waterfowl and important spawning and foraging habitat for several species of commercially important finfish and shellfish. Physical structure provided by seagrasses affords juveniles refuge from...

Southeastern freshwater fishes Southeastern freshwater fishes
North America has the richest fauna of temperate freshwater fishes in the world, with about 800 native species in the waters of Canada and the United States. The center of this diversity is in the southeastern United States, where as many as 500 species may exist (62% of the continental fauna north of Mexico). Many coastal marine species also enter fresh waters of the Southeast, and at...

Integration of manatee life-history data and population modeling Integration of manatee life-history data and population modeling
Aerial counts and the number of deaths have been a major focus of attention in attempts to understand the population status of the Florida manatee (Trichechus manatus latirostris). Uncertainties associated with these data have made interpretation difficult. However, knowledge of manatee life-history attributes increased and now permits the development of a population model. We describe a
