This classic by the distinguished Harvard entomologist tells how life on earth evolved and became diverse, and now, how diversity and life are endangered by us, truly. While Wilson contributed a great deal to environmental ethics by calling for the preservation of whole ecosystems rather than individual species, his environmentalism appears too anthropocentric: "We should judge every scrap of biodiversity as priceless while we learn to use it and come to understand what it means to humanity." And: "Signals abound that the loss of life's diversity endangers not just the body but the spirit." This reprint of the 1992 Belknap Press publication contains a new foreword.

The more we study the world around us, the more living things we discover every day. The planet is full of millions of species of plants, birds, animals, and microbes, and every single one including us is part of a big, beautiful, complicated pattern. When humans interfere with parts of the pattern, by polluting the air and oceans, taking too much from the sea, and cutting down too many forests, animals and plants begin to disappear. What sort of world would it be if it went from having many types of living things to having just one?--

The diversity of living forms and the unity of evolutionary processes are the focus of these essays. The collection helps form much of the basis of contempoary undertanding of evolutionary biology.

This sophisticated coloring book is a beautifully detailed illustration of the world's living diversity. It is written for science students, teachers, and anyone else who is curious about the extraordinary variety of living things that inhabit this planet. It opens with an introduction to the classification systems, distinctions between prokaryotic and eukaryotic cells, an introduction to life cycles, Earth history, and an explanation of how to best use this coloring book. The next section is organized by communities in which the organisms live. The final section details the variety of major groupings - phyla - within each kingdom and shows how the organisms in each are distinguished from one other. This coloring book gives a visual understanding of the enormous diversity of life on this planet and will be an enlightening and educational resource for students from a variety of backgrounds.

The lavish array of organisms known as "biodiversity" is an intricately linked web that makes the Earth a uniquely habitable plane. In this book, a noted science writer examines the threats posed to humans by the loss of biodiversity and explains key findings from the ecological sciences. It is the first book of its kind to clearly explains the practical consequences of declining biodiversity of ecosystem hjealth and function and, consequently, on human society.

This study, first published in 1942, helped to revolutionize evolutionary biology by offering a new approach to taxonomic principles, and correlating the ideas and findings of modern systematics with those of other life disciplines. This book is one of the foundational documents of the Evolutionary Synthesis. It is the book in which Ernst Mayr pioneered his concept of species based chiefly on such biological factors as interbreeding and reproductive isolation, taking into account ecology, geography and life history. In the introduction to this edition, Mayr reflects on the place of this work in the subsequent history of his field.

This important book for scientists and nonscientists alike calls attention to a most urgent global problem: the rapidly accelerating loss of plant and animal species to increasing human population pressure and the demands of economic development. Based on a major conference sponsored by the National Academy of Sciences and the Smithsonian Institution, Biodiversity creates a systematic framework for analyzing the problem and searching for possible solutions.

Eloquent, practical and wise, this book by one of the world’s most important scientists—and two time Pulitzer Prize winner—should be read and studied by anyone concerned with the fate of the natural world. It "makes one thing clear ... we know what we do, and we have a choice" (The New York Times Book Review). E.O. Wilson assesses the precarious state of our environment, examining the mass extinctions occurring in our time and the natural treasures we are about to lose forever. Yet, rather than eschewing doomsday prophesies, he spells out a specific plan to save our world while there is still time. His vision is a hopeful one, as economically sound as it is environmentally necessary.

Labeling exercises, self-quizzes, review questions, and critical thinking exercises help students with retention and better test results.

Such is the pressure on teaching time in schools and universities that students are taught less and less of the diversity that is life on this planet. Most students, and indeed most professional biologists that these students become, know far more of cell function than of biodiversity. This text is a profusely illustrated, quick-reference guide to all types of living organisms, from the single-celled prokaryotes and eurkaryotes to the multicellular fungi, plants and animals. All surviving phyla and their component classes are characterised and described, as are their lifestyles, ecology, relationships, and within-group diversity (with orders displayed in list form). Overall, the book's aim is to provide biologists and others with a clear, concise picture of the nature of all groups of organisms with which they may be unfamiliar.
