Wind damage effects of Hurricane Andrew on mangrove communities along the southwest coast of Florida, USA Wind damage effects of Hurricane Andrew on mangrove communities along the southwest coast of Florida, USA
On August 24, 1992, Hurricane Andrew downed and defoliated an extensive swath of mangrove trees across the lower Florida peninsula. Permanent field sites were established to assess the extent of forest damage and to monitor the rate and process of forest recovery. Canopy trees suffered the highest mortality particularly for sites within and immediately north of the storm's eyewall. The...

Dicofol and DDT residues in lizard carcasses and bird eggs from Texas, Florida, and California Dicofol and DDT residues in lizard carcasses and bird eggs from Texas, Florida, and California
Dicofol is an organochlorine agricultural pesticide used to control mites. The principal commercial dicofol product is known as Kelthane TM. More than 70% of dicofol product (about 3 million Ib or 1.4 million kg) sold annually in the U.S. is applied in California, Arizona, Texas, and Florida. Florida citrus and California cotton receive more than half the total (Clark 1990). In...

Identification of sex in hatchling loggerhead turtles (Caretta caretta) by analysis of steroid concentrations in chorioallantoic/amniotic fluid Identification of sex in hatchling loggerhead turtles (Caretta caretta) by analysis of steroid concentrations in chorioallantoic/amniotic fluid
A major difficulty in sea turtle conservation is the inability to nonlethally and noninvasively identify the sex of hatchling sea turtles. Traditional sexing techniques such as plasma sex steroid quantification cannot be applied to hatchlings without sacrificing the hatchlings or utilizing invasive procedures. This paper presents a technique for sexing hatchling sea turtles by analysis...

Reproduction and early-age survival of manatees at Blue Spring, Upper St. Johns River, Florida Reproduction and early-age survival of manatees at Blue Spring, Upper St. Johns River, Florida
We summarize reproduction of adults and survival of calves and subadult Florida manatees (Trichechus manatus latirostris) that were identified in winter at Blue Spring on the upper St. Johns River in Florida. Some records span more than 20 years, but most are from 15-year continuous annual observations during winter 1978-79 through winter 1992-93. Fifty-seven, first-year calves were...

Coastal ecosystem decision‐support GIS: Functions and methodology Coastal ecosystem decision‐support GIS: Functions and methodology
To solve coastal resource and environmental issues and handle complex spatial data and information effectively and efficiently, a coastal ecosystem decision‐support geographic information system (GIS) is being developed at the Southern Science Center of the U.S. National Biological Service. With three subsystems, natural resource management, environmental impact assessment, and data and

Florida manatees Florida manatees
The endangered Florida manatee (Trichechus manatus latirostris) is a survivor. It is one of only three living species of manatees which, along with their closest living relative, the dugong (Dugong dugon), make up the Order Sirenia. This taxonomic distinctiveness reflects their evolutionary and genetic uniqueness. Sirenians are the only herbivorous marine mammals; manatees feed on...
