Some Thoughts on Using a Landscape Framework to Address Cumulative Impacts on Wetland Food Chain Support

摘要

A landscape-level approach is derived to hierarchically separate the nation's wetlands into ecological regions. The classification scheme allows for the predetermination of the environmental constraints and possible natural limits of the wetlands food chain support. A discussion follows that uses existing data on food webs to further classify wetlands into resistant or resilient ecosystems. The information can then be employed in formulating cumulative impact predictors. With the help of these predictors and extant models on resource productivity a model is suggested to predict the movement of animals between wetland patches. The suggested model is derived from entropy maximization principles and is based in spatial location theory. (Copyright (c) 1988 Springer-Verlag.)
