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 storm even

Gauging the impact of manipulative activities, such as rehabilitation or management, on wetlands requires having a notion of the unmanipulated condition as a reference. An understanding of the reference condition requires knowledge of dominant factors influencing ecosystem processes and biological communities. In this paper, we focus on natural physical factors (conditions and processes) that d

Hydrogeomorphic factors and ecosystem responses in coastal wetlands of the Great Lakes
Gauging the impact of manipulative activities, such as rehabilitation or management, on wetlands requires having a notion of the unmanipulated condition as a reference. And understanding of the reference condition requires knowledge of dominant factors influencing ecosystem processes and biological communities.

Vulnerability of coastal wetlands in the Southeastern United States: climate change research results, 1992-97
As part of the USGCRP research framework on coastal lands and ecosystems, the Biological Resources Division of the U.S. Geological Survey (National Wetlands Research Center) entered into partnership with Rice University, Louisiana State University, Duke University, Clemson University, University of Southwestern Louisiana, University of Georgia, and the Virginia Institute of Marine Studies (Univers

Understory plant species composition in remnant stands along an urban-to-rural land-use gradient
We examined the understory species composition of 24 remnant forest stands along an urban-to-rural gradient in the metropolitan Milwaukee, Wisconsin region to determine the relationships between plant community composition, human disturbance, and contrasting types of land use along a gradient of urbanization. A significant difference was found in shrub species community composition among three con

Coastal wetlands and global change: overview
The potential impacts of climate change are of great practical concern to those interested in coastal wetland resources. Among the areas of greatest risk in the United States are low-lying coastal habitats with easily eroded substrates which occur along the northern Gulf of Mexico and southeast Atlantic coasts. The Intergovernmental Panel on Climate Change (IPCC) and the World Meteorological Organ

Global change and submerged aquatic vegetation research
Communities of submerged aquatic vegetation (SAY) are important components of many freshwater, brackish, and marine
aquatic ecosystems. They prevent erosion by baffling the impacts of waves, especially from storms. These aquatic plant
communities remove nutrients and other pollutants from river and runoff inputs to coastal areas, preventing their entry into
surrounding waters. They provide nursery

Disturbance and recovery of the Louisiana coastal marsh landscape from the impacts of Hurricane Andrew
The impact of Hurricane Andrew on the Louisiana coastal landscape and the initial recovery of wetland plant communities was determined from extensive surveys of a large geographic region of coastal marsh near Atchafalaya Bay and intensive studies of an oligohaline marsh on Otter Bayou. Wind and water movements associated with the hurricane resulted in the formation of compressed marsh, thick sedim

The interactive effects of herbivory and fire on an oligohaline marsh, Little Lake, Louisiana, USA
Herbivory and fire have been shown to affect the structure and composition of marsh communities. Because fire may alter plant species composition and cover, and these alterations may have an effect on herbivore populations or foraging patterns, an interactive effect of herbivory and fire may be expected. In this study, the effects of fire and vertebrate herbivory in a Louisiana oligohaline marsh w
