Summary

Symposium 17: Proceedings from “Evolution and the Aquatic Ecosystem Symposium,” held in Monterey, California, May 1994

Identifying units for conservation is now, and will likely remain, a complicated judgment call. A consensus process that addresses many factors is important to decisions about significant units of biodiversity. Thirty-six papers from a May 1994 symposium address conservation of aquatic diversity from an evolutionary and ecological point of view. This book represents the latest thinking on an issue that links the regulatory and scientific communities: evolutionarily significant units in conservation biology.

This book is intended for:

* conservation biologists * ecologists * policy makers
