"[...]overlap over an extensive geographic range throughout the year without interbreeding—thus reacting toward one another as do full species—so far as I know has not previously been found to exist in mammals. The overlapping end-members of the chain of subspecies of Sorex vagrans really do coexist; specimens of the overlapping subspecies have been taken together at the same localities from California to British Columbia. I have taken a specimen of S. v. vagrans and several of S. v. setosus in the same woodlot at Fort Lewis, Pierce County,[...]".

"In the past 40 years an amazing amount of data has been accumulated and analyzed on all aspects of the natural history of Point Reyes. Jules Evens has taken the difficult job of tackling an almost impossibly complicated subject and has succeeded masterfully. Natural History of the Point Reyes Peninsula provides an overview of not just the peninsula, but also adjacent land and ocean habitats, as well as thoughtful insights gleaned from research. The overwhelming draw to this area is observing some part of its natural history, and this book provides an intelligent summary of past and present knowledge."—Bob Stewart, former Naturalist in Residence for the Point Reyes National Seashore and author of Butterflies of Arizona: A Photographic Guide

From the polar bear and the gray wolf to the walrus and river otter, there are 115 species of mammals in Alaska that have never been fully catalogued until now. Biologists Joseph A. Cook and Stephen O. MacDonald have compiled here the first comprehensive guide to all of Alaska’s mammals, big and small, endearing and ferocious. Through extensive fieldwork and research the authors have produced a unique and authoritative reference. Detailed entries for each species include distribution and taxonomic information, status, habitat, and fossil history. Appendices include quick reference listings of mammal distribution by region, specimen locations, conservation status, and the incidence of Pleistocene mammals. The guide is generously illustrated with line drawings by Alaskan artist W. D. Berry and includes several maps indicating populations and locations of species. Mammals of Alaska will be an accessible, easy to use source for scholars and hobbyists alike.
