Coastal wetlands and global change: overview 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...

Global change and submerged aquatic vegetation research 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...

Disturbance and recovery of the Louisiana coastal marsh landscape from the impacts of Hurricane Andrew 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...

The interactive effects of herbivory and fire on an oligohaline marsh, Little Lake, Louisiana, USA 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...

The examination of a competition matrix for transitivity and intransitive loops The examination of a competition matrix for transitivity and intransitive loops
Recent examinations of competition matrices for transitivity (species A > species B > species C) have used techniques that can be subject to certain biases. First, recent theoretical and empirical analyses have shown that traditional measures of competitive performance are biased in favor of the larger species. It is argued that this size bias has the potential to bias analyses of...

Size bias in traditional analyses of substitutive competition experiments Size bias in traditional analyses of substitutive competition experiments
The objective of this study was to examine the claim that traditional measures of competitive performance in substitutive experiments are biased towards larger plants. Results from a three-year diallele experiment of 6 marsh plant species were analyzed using both Relative Yields (a traditional analysis) and the Relative Efficiency Index (a recently proposed analysis presumed to be size...
