Paperback. Condición: Good. As the Earth's number of species decreases, biologists have been concerned particularly with general decline in amphibian populations, viewing them as particularly sensitive indicators of the health of the environment. Yet one of the most difficult problems in conservation biology is the lack of baseline data against which to measure population changes. Measuring and Monitoring Biological Diversity is the first book to provide comprehensive coverage of standard methods for biodiversity sampling of amphibians, with information on analyzing and using data that will interest biologists in general. In this manual, nearly fifty herpetologists recommend ten standard sampling procedures for measuring and monitoring amphibian and many other populations. The contributors discuss each procedure, along with the circumstances for its appropriate use. In addition, they provide a detailed protocol for each procedure's implementation, a list of necessary equipment and personnel, and suggestions for analyzing the data. The data obtained using these standard methods are comparable across sites and through time and, as a result, are extremely useful for making decisions about habitat protection, sustained use, and restoration - decisions that are particularly relevant for threatened amphibian populations.…

Paperback. Condición: Good. Debate on the threat to humanity posed by the massive and widespread loss of biological diversity has largely emphasized economic and ecological consequences. In The Value of Life, a leading social scientist adds a critical new dimension. Stephen R. Kellert explores the actual and perceived importance of biological diversity for humankind's physical, emotional, intellectual, and even spiritual well-being. Kellert identifies ten basic values, which he describes as biologically based, inherent human tendencies that are greatly influenced and moderated by culture, learning, and experience. Throughout, Kellert argues that the preservation of biodiversity is fundamentally linked to human well-being as he illustrates the importance of biological diversity to the human sociocultural and psychological condition. His discussion provides the reader with a deeper understanding of how humans depend on a vast matrix of affiliations with other living things to achieve lives rich in meaning and value.…
