Biology of Small Mammals

Joseph F. Merritt is a senior mammalogist with the Illinois Natural History Survey, University of Illinois Urbana-Champaign, holding courtesy academic appointments at the University of Colorado, Indiana State University, and SUNY's College of Environmental Science and Forestry. He is the coauthor of Mammalogy: Adaptation, Diversity, Ecology, also published by Johns Hopkins.

Any college-level natural history library needs this survey. Midwest Book Review 2010 Highly recommended. Choice 2010 Utilizing fossil records and extant small mammals, the author provides an interesting look into their physical make up and way of life. Wildlife Activist 2010 Where Dr. Merritt's book shines and separates itself from other mammalogy books is when he adds the details, examples, and colorful commentary allowing readers to share his passion and enthusiasm for small mammals... Dr. Merritt manages to keep these passages both rigorous and entertaining, the true mark of a fine teacher. -- Robert McCleery Journal of Wildlife Management 2010 Merritt writes with evident enthusiasm for his subject, he is impressively up to date on most topics, and the book is copiously illustrated. -- William Z. Likicker Jr. Bioscience 2011
