Any scientific discipline needs a theoretical framework to guide its development and to sharpen the questions its researchers pursue. In biology, evolution is the grand theoretical framework, and an his torical perspective is necessary to understand present-day biological conditions. In its formative years, the modern study of the fruit-frugivore mutualism was guided by the 'specialist-generalist' paradigm developed by D. Snow, D. McKey, and H. Howe. Howe reviews the current status of this evolution ary paradigm and points out that it has been dismissed by many workers before being adequately...

The second largest order of mammals, "Chiroptera "comprises more than one thousand species of bats. Because of their mobility, bats are often the only native mammals on isolated oceanic islands, where more than half of all bat species live. These island bats represent an evolutionarily distinctive and ecologically significant part of the earth s biological diversity.
"Island Bats "is the first book to focus solely on the evolution, ecology, and conservation of bats living in the world s island ecosystems. Among other topics, the contributors to this volume examine how the earth s history...

In the darkness of the star-studded desert, bats and moths feed on the nectar of night-blooming cactus flowers. By day, birds and bees do the same, taking to blooms for their sweet sustenance. In return these special creatures pol-linate the equally intriguing plants in an ecological circle of sustainability. The Sonoran Desert is the most biologically diverse desert in the world. Four species of columnar cacti, including the iconic saguaro and organ pipe, are among its most conspicuous plants. No Species Is an Island describes Theodore H. Fleming's eleven-year study of the...
