Many studies have reported that imported fire ants can have negative impacts to property, wildlife, and ecosystem integrity. Depredation by fire ants can reduce native insect diversity and survival of hatchling birds and reptiles, including gopher tortoises. Because of the potential impacts of fire ants on gopher tortoise recruitment, we assessed infestation levels of red imported fire ants on public and private forest lands in south Mississippi. Our study design focused on surveys for estimation of densities of fire ant mounds on suitable and priority soils for gopher tortoises. We...

Wetlands created by American beaver (Castor canandensis) provide habitat for a diversity of resident and migratory birds. To estimate bird community characteristics of beaver wetlands and adjacent riparian forests, we conducted point count surveys in five beaver wetlands and adjacent floodplain ridges of first- and second-order streams during winter 2001-2002 and spring 2002 in central Mississippi. Ninety bird species were recorded in beaver wetlands and 69 bird species were detected in adjacent upland forests. In beaver wetlands, we recorded 57 species during winter 2001-2002 and 69...
