Importance of the predator's ecological neighborhood in modeling predation on migrating prey Importance of the predator's ecological neighborhood in modeling predation on migrating prey

Most mathematical descriptions of predator-prey interactions fail to take into account the spatio-temporal structures of the populations, which can lead to errors or misinterpretations. For example, a compact pulse of prey migrating through a field of quasi-stationary predators may not be well described by standard predator-prey models, because the predators and prey are unlikely to be...

. Ecological conceptual models: a framework and case study on ecosystem management for South Florida sustainability . Ecological conceptual models: a framework and case study on ecosystem management for South Florida sustainability

The Everglades and South Florida ecosystems are the focus of national and international attention because of their current degraded and threatened state. Ecological risk assessment, sustainability and ecosystem and adaptive management principles and processes are being used nationally as a decision and policy framework for a variety of types of ecological assessments. The intent of this...

The U.S. National Amphibian Research and Monitoring Initiative and the role of protected areas The U.S. National Amphibian Research and Monitoring Initiative and the role of protected areas

In response to concerns about the worldwide status of amphibians (Alford and Richards 1999; Bury 1999; Daszak et al. 1999; Houlahan et al. 2000), Congress in Fiscal Year 2000 provided initial support to agencies of the U.S. Department of the Interior for research and monitoring of amphibians. Most funds came to the U.S. Geological Survey (USGS), but additional funds for the U.S. Fish and...

Population dynamics and the ecological stability of obligate pollination mutualisms Population dynamics and the ecological stability of obligate pollination mutualisms

Mutualistic interactions almost always produce both costs and benefits for each of the interacting species. It is the difference between gross benefits and costs that determines the net benefit and the per-capita effect on each of the interacting populations. For example, the net benefit of obligate pollinators, such as yucca and senita moths, to plants is determined by the difference...

The importance of competition in regulating plant species abundance along a salinity gradient The importance of competition in regulating plant species abundance along a salinity gradient

Current theories differ in their predictions concerning the effects of interspecific interactions on species growth and distribution along environmental gradients. In this study, we examined the influence of competition on species composition across a salinity gradient. This work involved three common fresh and brackish marsh species. The three species, Spartina patens, Sagittaria...
