Description
Book SynopsisProvides a discussion of bat biology and evolution as well as regional physiography and zoogeography. This book describes the behaviour and ecology of the 31 species of bats found in Montana, Idaho, Wyoming, Utah, Colorado, New Mexico, and Arizona. It features colour photographs and illustrations, distribution maps, and echolocation sonograms.
Table of ContentsCONTENTS Acknowledgments I. Introduction A powerful misunderstanding How much do we know? Origin of "batness" The structure of bats Bats today "Seeing" in complete darkness Echolocation: seeing with ears is not as easy as it sounds Echolocation pulse rates: speed kills CF versus FM bats: changing the channel is not optional Nature's arm-race: the insects fight back The world-wide importance of bats An unfortunate loss of biodiversity II. Physiography and Zoogeography of the Rocky Mountain Region Northern, Central, and Southern Rockies Geology Hydrology Climate Vegetation & Life Zones Desertscrub Desertscrub and bats Semidesert scrublands Pinon-juniper woodland Semidesert scrub, pinon-juniper woodlands and bats Chaparral Chaparral and bats Plains and desert grasslands Grasslands and bats Montane shrubland Montane shrubland and bats Montane forest Montane forest and bats Subalpine Forest Subalpine forest and bats Alpine tundra Alpine tundra and bats Riparian systems Riparian systems and bats Transition Zones North versus South-Facing Slopes Barriers to dispersal North-South corridors: the Canadian/Mexican connection III. Evolutionary Origins of Rocky Mountain Bats Bat origins: what do fossils say? North American bat fauna: mysterious origins Divergence of temperate from tropical forms: some like it not so hot Today's Temperate Bats Special adaptations to temperate environments: when heaven freezes over Torpor Hibernation Migration IV. Bats in Rocky Mountain Ecosystems Ecosystems of the Rockies: hotbeds of biodiversity Bat Diversity & Elevation: It's lonely at the top and the bottom Community structure of Rocky Mountain bats The shapes of bats: round pegs in round holes Shapes and sizes of wings: fitting in with the crowd Aerial versus gleaning insectivory: how picky should one be? The shapes and sizes of ears: better hearing or just plain cool Bats as natural insecticides: balancing the diet Other foraging modes: bats that really suck Water: simply a drink, or mineral sink? Potential competitors: poorwills, rich bats, and sneaky mice V. Rocky Mountain Bat Conservation Strategies Where do bats occur? Mountains: their effect on and importance to conservation efforts Protecting roost sites Protecting foraging habitat Importance of old-growth forests Protecting water resources Environmental contaminants and bats Wind turbines & communication towers Human-made structures and bats Bat houses: do they work? The future of bats. Accounts of Species Key to the Bats of the Rocky Mountains A. FAMILY MORMOOPIDAE 1. Ghost-faces Bat (Mormoops megalophylla) a. Description b. Distribution c. Ecology & Behavior d.
