The effects of landscape position on plant species density: Evidence of past environmental effects in a coastal wetland The effects of landscape position on plant species density: Evidence of past environmental effects in a coastal wetland
Here we propose that an important cause of variation in species density may be prior environmental conditions that continue to influence current patterns. In this paper we investigated the degree to which species density varies with location within the landscape, independent of contemporaneous environmental conditions. The area studied was a coastal marsh landscape subject to periodic...

Recent advances in life history of Gulf of Mexico sturgeon, Acipenser oxyrinchus desotoi, in the Suwannee River, Florida, USA: A synopsis Recent advances in life history of Gulf of Mexico sturgeon, Acipenser oxyrinchus desotoi, in the Suwannee River, Florida, USA: A synopsis
Gulf sturgeon spawn on portions of three sites in the upper Suwannee River, which may appropriately be described as spawning reefs. The same areas are utilized from year to year. Habitat factors important in spawning site determination include gravel/cobble substrate, the presence of eddy fields, a neutral to slightly alkaline pH, and an empirically observed range in calcium ion content...

Parasites and commensals of the West Indian manatee from Puerto Rico Parasites and commensals of the West Indian manatee from Puerto Rico
Metazoan parasites and commensals were collected from dead manatees salvaged in Puerto Rico. Thirty-five manatees were examined between 1980 and 1998. Parasites and commensals were identified in 20 (57%) manatees and included 3 species of helminths, 1 nematode (Heterocheilus tunicatus) and 2 digeneans (Chiorchis fabaceus and Cochleotrema cochleotrema). Two species of commensals were also

Modeling the effects of nutria (Myocastor coypus) on wetland loss Modeling the effects of nutria (Myocastor coypus) on wetland loss
We created a model to study the process in which nutria (Myocastor coypus) feeding activities lead to erosion and loss of marsh area. This model ties together data on nutria population dynamics and feeding behavior from the literature with data from field studies on the phenology of Scirpus americanus and Spartina patens conducted in the Barataria Basin, Louisiana, USA in 1992. The...

Management implications of fish trap effectiveness in adjacent coral reef and gorgonian habitats Management implications of fish trap effectiveness in adjacent coral reef and gorgonian habitats
A combination of visual census and trap sampling in St. John, USVI indicated that traps performed better in gorgonian habitat than in adjacent coral reef habitat. Although most families were seen more commonly in coral habitat, they were caught more often in gorgonian areas. Traps probably fished more effectively in gorgonian habitats, especially for migrating species, because traps...
