With more than 1,400 species, bats are an incredibly diverse and successful group of mammals that can serve as model systems for many unique evolutionary adaptations. Flight has allowed them to master the sky, while echolocation enables them to navigate in the dark. Being small, secretive, nocturnal creatures has made bats a challenge to study, but over the past 50 years, innovative research has made it possible to dispel some of the mystery and myth surrounding them to give us a better understanding of the role these animals play in the ecosystem. The structure of the book is based on several broad themes across the biological sciences, including the evolution of bats, their ecology and behavior, and conservation of biodiversity. Within these themes are more specific topics on important aspects of bat research, such as morphology, molecular biology, echolocation, taxonomy, systematics, threats to bats, social structure, reproduction, movements, and feeding strategies. Given its scope, the book will appeal to the wider scientific community, environmental organizations, and government policymakers who are interested in the interdisciplinary aspects of biology and nature.

Presents a guide to what scientists know about bats, detailing their origins, evolution, diet, habitat, reproductive process, and social structure, and offers a discussion of echolocation and these mammals' role in the ecosystem.
Basing the volume on archival materials, Geoffrey Martin explains not only what American geographers did, but also why they chose the paths they took. The letters upon which the volume relies enable Martin to enter the minds of our predecessors in ways that histories based on secondary sources cannot. By tracing interpersonal connections among domestic geographers, and with overseas colleagues (especially in Germany and France), Martin sheds new light on the intellectual and structural foundations of American geography.
