As the loss of natural habitats and their resident species continues unabated, Bat Biology and Conservation, skilfully put together by chiroptera gurus Kunz and Racy, documents efforts to investigate bats in both tropical and temperate ecosystems. Compiled from the Tenth International Bat Research Conference at Boston University on August 6-11, 1995 it presents recent research and synthetic reviews by more than thirty of the world's leading authorities on bats, and discusses physiology and evolution, functional morphology, echolocation, and conservation biology. Several contributors focus on long-standing problems in bat systematics and illustrate the value of well-substantiated phylogenetic hypotheses for understanding diverse biological patterns. Others emphasize the importance of investigating both form and function and consider how morphological and ecological constraints influence flight, mastication, and the sensory systems used in echolation. Still others consider the conservation status of bats in most regions of the world and discuss the protection of both roosting and foraging habitats. Bat Biology and Conservation is an essential reference not only for bat scientists but also for conservation biologists and those working with other mammalian groups.
