Atlantic white cedar plantings in St. Tammany Parish, Louisiana, and the Bogue Chitto National Wildlife Refuge, Mississippi Atlantic white cedar plantings in St. Tammany Parish, Louisiana, and the Bogue Chitto National Wildlife Refuge, Mississippi
Populations of Atlantic white cedar (Chamaecyparis thyoides (L.) B.S.P.) growing at the extreme western range of the species are in danger of being lost, and information on the ecology of these populations is limited. Seeds and seedlings ("wildlings") were collected near Vancleave, MS. The wildlings were transplanted to bay-head sites on Bogue Chitto National Wildlife Refuge where canopy...

USGS develops a drainage-based system to track ANS introductions USGS develops a drainage-based system to track ANS introductions
The U.S. Geological Survey (USGS) Nonindigenous Aquatic Species (NAS) Program has tracked the distribution of introduced species for more than 20 years. This effort began with foreign fishes in Florida and later expanded to include aquatic nuisance species nationwide. The tracking database contains locational and temporal data for introductions and spread. This data is generally derived...

Spatial and temporal patterns of nonindigenous fish introductions in the United States Spatial and temporal patterns of nonindigenous fish introductions in the United States
In 1978 biologists in Gainesville, Florida, began compiling records on the distribution and status of nonindigenous fishes known in U.S. inland waters. The database, now in electronic format, currently contains approximately 17,000 records representing more than 500 nonindigenous fish taxa (i.e., species, hybrids, and unidentified forms). Of these taxa, 317 (61%) are native to the United...

Effects of environmental change on plant species density: Comparing predictions with experiments Effects of environmental change on plant species density: Comparing predictions with experiments
Ideally, general ecological relationships may be used to predict responses of natural communities to environmental change, but few attempts have been made to determine the reliability of predictions based on descriptive data. Using a previously published structural equation model (SEM) of descriptive data from a coastal marsh landscape, we compared these predictions against observed...

MOAB: a spatially explicit, individual-based expert system for creating animal foraging models MOAB: a spatially explicit, individual-based expert system for creating animal foraging models
We describe the development, structure, and corroboration process of a simulation model of animal behavior (MOAB). MOAB can create spatially explicit, individual-based animal foraging models. Users can create or replicate heterogeneous landscape patterns, and place resources and individual animals of a goven species on that landscape to simultaneously simulate the foraging behavior of...

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...
