A critical examination of current knowledge and ideas on cave biology, with emphasis on evolution, ecology, and conservation.
Biospeleology, the study of organisms that live in caves, has a tremendous potential to inform many aspects of modern biology; yet this area of knowledge remains largely anchored in neo-Lamarckian views of the natural world in both its approaches and jargon. Written for graduate students and academic researchers, this book provides a critical examination of current knowledge and ideas on cave biology, with emphasis on evolution, ecology, and conservation. Aldemaro Romero provides a historical analysis of ideas that have influenced biospeleology, discusses evolutionary phenomena in caves, from cave colonization to phenotypic and genotypic changes, and integrates concepts and knowledge from diverse biological viewpoints. He challenges the conventional wisdom regarding the biology of caves, and highlights urgent questions that should be addressed in order to get a better and more complete understanding of caves as ecosystems.

The true tales in this collection will take readers from the chicken houses of Arkansas to the caves of Venezuela and Mexico to the coast of Alaska. These fifteen adventures range from amusing to life threatening. Some are filled with suspense and danger in exotic places, while others document more routine but important biological field and lab work. Meet the roommate with the rash that wouldn't go away, a friendly bull, some blind cave fish, killer whales, drug smugglers, and hairy roots that are used to produce new medicines. Read about researchers crawling through rotten-egg-smelling muck in search of an elusive mosquitofish, diving into the cold black water of the White River in search of mussels, flying with bush pilots in Alaska, and working with David Attenborough in Arkansas. Here are teachers and researchers, biologists all, all from one university, real people who get their feet wet and their hands dirty in the pursuit of knowledge.
This book is a collection of readings that explore environmental issues in Latin America and the Caribbean using natural science and social science methods. These papers demonstrate the value of interdisciplinary approaches to analyze and solve environmental problems. The essays are organized into five parts: conservation challenges; national policies, local communities, and rural development; market mechanisms for protecting public goods; public participation and environmental justice; and the effects of development policies on the environment.
