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...

The use of resighting data to estimate the rate of population growth of the snail kite in Florida The use of resighting data to estimate the rate of population growth of the snail kite in Florida
The rate of population growth (lambda) is an important demographic parameter used to assess the viability of a population and to develop management and conservation agendas. We examined the use of resighting data to estimate lambda for the snail kite population in Florida from 1997-2000. The analyses consisted of (1) a robust design approach that derives an estimate of lambda from...

Genetic diversity in a morphologically conservative invasive taxon: Multiple introductions of swamp eels to the southeastern United States Genetic diversity in a morphologically conservative invasive taxon: Multiple introductions of swamp eels to the southeastern United States
Genetic analysis of introduced populations, especially in morphologically conservative taxa, can clarify introduction histories, identify management units and source populations, provide a more realistic estimate of the frequency of successful invasion, and suggest strategies for preventing further introductions. In the last 7 years, populations of swamp eels, referred to the Asian genus
