Structural instability, multiple stable states, and hysteresis in periphyton driven by phosphorus enrichment in the Everglades Structural instability, multiple stable states, and hysteresis in periphyton driven by phosphorus enrichment in the Everglades

Periphyton is a key component of the Everglades ecosystems. It is a major primary producer, providing food and habitat for a variety of organisms, contributing material to the surface soil, and regulating water chemistry. Periphyton is sensitive to the phosphorus (P) supply and P enrichment has caused dramatic changes in the native Everglades periphyton assemblages. Periphyton also...

Community food webs Community food webs

Community food webs describe the feeding relationships, or trophic interactions, between the species of an ecological community. Both the structure and dynamics of such webs are the focus of food web research. The topological structures of empirical food webs from many ecosystems have been published on the basis of field studies and they form the foundation for theory concerning the mean...

The importance of functional form in optimal control solutions of problems in population dynamics The importance of functional form in optimal control solutions of problems in population dynamics

Optimal control theory is finding increased application in both theoretical and applied ecology, and it is a central element of adaptive resource management. One of the steps in an adaptive management process is to develop alternative models of system dynamics, models that are all reasonable in light of available data, but that differ substantially in their implications for optimal...

A review of the literature on the worldwide distribution, spread of, and efforts to eradicate the coypu (Myocastor coypus) A review of the literature on the worldwide distribution, spread of, and efforts to eradicate the coypu (Myocastor coypus)

We conducted a literature review of coypu (Myocastor coypus) introduction and eradication efforts worldwide. The coypu (also called nutria) has been introduced from its origins in South America to every continent except Australia and Antarctica. While perceived in some regions as a valuable resource, in most regions the animals are considered a pest species. Coypus have caused damage to...

Interspecific differences in susceptibility to competition and predation in a species-pair of larval amphibians Interspecific differences in susceptibility to competition and predation in a species-pair of larval amphibians

Fundamental issues in the study of predator-prey interactions include addressing how prey coexist with their predators and, moreover, whether predators promote coexistence among competing prey. We conducted a series of laboratory experiments with a freshwater assemblage consisting of two predators that differed in their foraging modes (a crayfish, Procambarus sp., and the western...

Modeling the bathymetry of Catahoula Lake: Specialized technology for wetland management Modeling the bathymetry of Catahoula Lake: Specialized technology for wetland management

Catahoula Lake is the largest natural freshwater lake in Louisiana, covering more than 46 square miles (120 km2) (fig. 1). The lake is a principal stopover and wintering site for hundreds of thousands of migratory waterfowl and shorebirds. Scientists from the USGS National Wetlands Research Center are applying some of the research facility's specialties?wetland plant research, aerial and...
