Special Section on Creating Bayesian Belief Network Models in Ecology

What Are "Bayesian Belief Network Models?" Bruce G. Marcot 24 April 2005 In short, a Bayesian belief network (BBN) is simply a way of showing how things interact and cause specific outcomes.

One facet of modeling wildlife-habitat relations and species-environment relations may pertain to depicting the ecological roles played by organisms. I have termed these "key ecological functions" or KEFs.

A new Species-Environment Relations (SER) modeling approach depicts key ecological functions (KEFs) and key environmental correlates (KECs) of terrestrial plant and animal species, as part of a regional assessment of the Interior Columbia Basin Ecosystem Management Project. Assessing KEFs of species is one facet of understanding management effects and ecological integrity of ecosystems. A relational database was developed that ties species' KEFs with their key habitats, KECs, and distribution maps. In this way, potential management activities can be evaluated for how they influence: habitats and environmental correlates; associated plant, invertebrate, and vertebrate species; the array of ecological functions associated with those species; geographic functional ecology; and potential effects on ecosystem productivity, diversity, and sustainability.
