This field guide includes all the flora and fauna you're most likely to see in the forests of eastern North America. With 53 full-color plates and 80 color photos illustrating trees, birds, mammals, wildflowers, mushrooms, reptiles, amphibians, butterflies, moths, beetles, and other insects.

This full-color illustrated textbook offers the first comprehensive introduction to all major aspects of tropical ecology. It explains why the world's tropical rain forests are so universally rich in species, what factors may contribute to high species richness, how nutrient cycles affect rain forest ecology, and how ecologists investigate the complex interrelationships among flora and fauna. It covers tropical montane ecology, riverine ecosystems, savanna, dry forest--and more.Tropical Ecology begins with a historical overview followed by a sweeping discussion of biogeography and evolution, and then introduces students to the unique and complex structure of tropical rain forests. Other topics include the processes that influence everything from species richness to rates of photosynthesis: how global climate change may affect rain forest characteristics and function; how fragmentation of ecosystems affects species richness and ecological processes; human ecology in the tropics; biodiversity; and conservation of tropical ecosystems and species.Drawing on real-world examples taken from actual research, Tropical Ecology is the best textbook on the subject for advanced undergraduates and graduate students.Offers the first comprehensive introduction to tropical ecologyDescribes all the major kinds of tropical terrestrial ecosystemsExplains species diversity, evolutionary processes, and coevolutionary interactionsFeatures numerous color illustrations and examples from actual researchCovers global warming, deforestation, reforestation, fragmentation, and conservationThe essential textbook for advanced undergraduates and graduate studentsSuitable for courses with a field component Leading universities that have adopted this book include:Biola UniversityBucknell UniversityCalifornia State University, FullertonColorado State University - Fort CollinsFrancis Marion UniversityMichigan State UniversityMiddlebury CollegeNorthern Kentucky UniversityOhio Wesleyan UniversitySt. Mary's College of MarylandSyracuse UniversityTulane UniversityUniversity of California, Santa CruzUniversity of Central FloridaUniversity of CincinnatiUniversity of FloridaUniversity of MissouriUniversity of New MexicoUniversity of North Carolina at Chapel HillUniversity of the West Indies

The idea of a balance of nature has been a dominant part of Western philosophy since before Aristotle, and it persists in the public imagination and even among some ecologists today. In this lively and thought-provoking book, John Kricher demonstrates that nature in fact is not in balance, nor has it ever been at any stage in Earth's history. He explains how and why this notion of a natural world in balance has endured for so long, and he shows why, in these times of extraordinary human influence on the planet's ecosystems, it is critical that we accept and understand that evolution is a fact of life, and that ecology is far more dynamic than we ever imagined. The Balance of Nature traces the fascinating history of the science of ecology and evolutionary biology, from the discipline's early innovators to the advent of Darwin and evolution, to the brilliant and inquisitive scientific minds of today. Blending insights and entertaining stories from his own remarkable life in science, Kricher reveals how evolution is a powerful engine that drives ecological change, how nature is constantly in flux and, in effect, quite naturally out of balance--and how notions to the contrary are misguided and ultimately hazardous to us all. The Balance of Nature forcefully argues that an understanding of the dynamic nature of ecology and evolution is essential to formulating policies of environmental ethics to guide humanity toward a more responsible stewardship of our planet's ecosystems.

The acclaimed guide to the ecology and natural history of the American tropics-now fully updated and expandedThe New Neotropical Companion is the completely revised and expanded edition of a book that has helped thousands of people to understand the complex ecology and natural history of the most species-rich area on Earth, the American tropics. Featuring stunning color photos throughout, it is a sweeping and cutting-edge account of tropical ecology that includes not only tropical rain forests but also other ecosystems such as cloud forests, rivers, savannas, and mountains. This is the only guide to the American tropics that is all-inclusive, encompassing the entire region's ecology and the amazing relationships among species rather than focusing just on species identification.The New Neotropical Companion is a book unlike any other. Here, you will learn how to recognize distinctive ecological patterns of rain forests and other habitats and to interpret how these remarkable ecosystems function-everything is explained in clear and engaging prose free of jargon. You will also be introduced to the region's astonishing plant and animal life.Informative and entertaining, The New Neotropical Companion is a pleasurable escape for armchair naturalists, and visitors to the American tropics will want to refer to this book before, during, and after their trip.Covers all of tropical AmericaDescribes the species and habitats most likely to be observed by visitorsIncludes every major ecosystem, from lowland rain forests to the high AndesFeatures a wealth of color photos of habitats, plants, and animals
