Conservation Priorities when Species Interact: The Noah's Ark Metaphor Revisited

Abstract

This note incorporates ecological interactions into the Noah's Ark problem. In doing so, we arrive at a general model for ranking in situ conservation projects accounting for species interrelations and provide an operational cost-effectiveness method for the selection of best preserving diversity projects under a limited budget constraint.
