    To understand almost any part of the tropical rain forest's fabulously complex web of life, one must first learn to identify a bewildering array of plants. Alwyn Gentry's landmark book, completed just before his tragic death in 1993, is the only field guide to the nearly 250 families of woody plants in the most species-rich region of South America.As a consummate field researcher, Gentry designed this guide to be not just comprehensive, but also easy to use in rigorous field conditions. Unlike many field guides, which rely for their identifications on flowers and fruits that are only present during certain seasons, Gentry's book focuses on characters such as bark, leaves, and odor that are present year-round. His guide is filled with clear illustrations, step-by-step keys to identification, and a wealth of previously unpublished data.All biologists, wildlife managers, conservationists, and government officials concerned with the tropical rain forests will need and use this field guide.Alwyn Gentry was one of the world's foremost experts on the biology of tropical plants. He was senior curator at the Missouri Botanical Garden, and was a member of Conservation International's interdisciplinary Rapid Assessment Program (RAP) team, which inventories the biodiversity of the most threatened tropical areas. From 1967 to 1993 he collected more than 80,000 plant specimens, many of them new to science.

    Adaptive Strategies and Population Ecology of Northern Grouse was first published in 1988. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions.This book is at once a major reference to the species of grouse that inhabit North America and the Holarctic and a synthesis of all the available data on their ecology, sociobiology, population dynamics, and management. The book undertakes to answer two long-standing questions in population ecology: what actually regulates the numbers within a population, and what are the breeding and survival strategies evolved in this northern environment? For Volume I, editors Arthur T. Bergerud and Michael W. Gratson have drawn together their own work and that of colleagues in North America, Iceland, and Norway—in all, eleven research studies, averaging six years' duration, on eight species of grouse. These studies deal with the blue and ruffed grouse of the forest habitat; the sharp-tailed grouse, prairie chicken, and sage grouse of the prairie or steppe; and the white-tailed, rick, and willow ptarmigan found in alpine and arctic tundras. The authors describe the rich repertoire of behavior patterns developed by the hen and the cock to achieve their two primary objectives—first, to stay alive, and then to breed. Volume II, primarily the work of Bergerud, synthesizes the evidence in Volume I and in the grouse research literature from a theoretical perspective. Several potentially controversial sociobiological hypotheses are advanced to account for flocking behavior, migration, dispersal, roosting and feeding behavior, mate choice and mating systems. The demographic analysis provides new insights into cycles of abundance, the limitation of numbers, and the demographic factors that determine densities. The contributors, besides Bergerud and Gratson: R.C. Davies, A. Gardarson, J.E. Hartzler, R.A. Huempfner, D.A. Jenni, D.H. Mossop, S. Myrberget, R.E. Page, R.K. Schmidt, W.D. Svedarsky, and J.R. Tester.

    Channing (biodiversity and conservation biology, U. of the Western Cape, South Africa) and Howell (zoology and marine biology, U. of Dar es Salaam, Tanzania) have written the first field guide and reference book on the amphibians of East Africa (Tanzania, Kenya, and Uganda), covering 194 frogs and toads and 9 caecilians. For each species, scientific names are explained and local names and other names in the literature are listed. Along with species descriptions, information is given on known habitat preferences and distribution, advertisement call, breeding biology, and known tadpoles, and key references. Prior to the species studies, there are chapters on the history of amphibian studies in East Africa, geography and environment, conservation, classification, and identification. Also included are 185 color photographs of various species. Annotation ©2006 Book News, Inc., Portland, OR (booknews.com)

    Attitudes to Animals provides a foundation that the reader can use to make ethical choices about animals. It will challenge readers to question their current views, attitudes, and perspectives on animals and the nature and development of the human-animal relationship. Human perspectives on the human-animal relationship reflect what we have learned, together with spoken and unspoken attitudes and assumptions, from our families, societies, media, education, and employment. This thought-provoking book delves into what it means to be human, what it means to be animal, and the nature of the relationship between them. This is accomplished with philosophical and ethical discussions, scientific evidence, and dynamic theoretical approaches.
