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 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.
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 Principles of Biology sequence (BI 211, 212 and 213) introduces biology as a scientific discipline for students planning to major in biology and other science disciplines. Laboratories and classroom activities introduce techniques used to study biological processes and provide opportunities for students to develop their ability to conduct research.
Biology has entered an era in which interdisciplinary cooperation is at an all-time high, practical applications follow basic discoveries more quickly than ever before, and new technologiesâ€"recombinant DNA, scanning tunneling microscopes, and moreâ€"are revolutionizing the way science is conducted. The potential for scientific breakthroughs with significant implications for society has never been greater. Opportunities in Biology reports on the state of the new biology, taking a detailed look at the disciplines of biology; examining the advances made in medicine, agriculture, and other fields; and pointing out promising research opportunities. Authored by an expert panel representing a variety of viewpoints, this volume also offers recommendations on how to meet the infrastructure needsâ€"for funding, effective information systems, and other supportâ€"of future biology research. Exploring what has been accomplished and what is on the horizon, Opportunities in Biology is an indispensable resource for students, teachers, and researchers in all subdisciplines of biology as well as for research administrators and those in funding agencies.
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.
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.
By using an issues-oriented approach, the new edition of this respected text grabs student interest with real-life issues that hit home. This text includes new coverage and pedagogy that encourages students to think critically about hot-button issues and includes outstanding new features that take students beyond memorization and encourage them to ask questions in new ways as they learn to interpret data.Show students how biology matters – Biology's connections to real life are reflected in every chapter of this new edition, beginning with opening Impacts, Issues essays—a brief case study on a biology-related isue or research finding and is revisited throughout the chapter, reminding students of the real-world significance of basic concepts. Additional, online exercises promote critical thinking about issues students will face as consumers, parents, and citizens.Link concepts from chapter to chapter – Links to Earlier Concepts appear near the Key Concepts, to help students remember what they've learned in earlier chapters and apply it to the new material to come. At the beginning of each section, students are reminded of the earlier link that is most appropriate for their current study.
This accessible and timely book provides a comprehensive overview of how to measure biodiversity. The book highlights new developments, including innovative approaches to measuring taxonomic distinctness and estimating species richness, and evaluates these alongside traditional methods such as species abundance distributions, and diversity and evenness statistics. Helps the reader quantify and interpret patterns of ecological diversity, focusing on the measurement and estimation of species richness and abundance. Explores the concept of ecological diversity, bringing new perspectives to a field beset by contradictory views and advice. Discussion spans issues such as the meaning of community in the context of ecological diversity, scales of diversity and distribution of diversity among taxa Highlights advances in measurement paying particular attention to new techniques such as species richness estimation, application of measures of diversity to conservation and environmental management and addressing sampling issues Includes worked examples of key methods in helping people to understand the techniques and use available computer packages more effectively
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.
