Long ago when people still lived in caves-perhaps at the same time when they developed habits that were different from those of other animals- humans began to practice ecology. They became keen observers of nature through such basic and instinctive actions as tracking both large wild animals and small prey, discerning edible plants from poisonous ones, and noting the time of year when different plants could be gathered. From necessity and inherent curiosity, humans began to learn about the relationships between living things and the environment. As the field of ecology grew, its focus went beyond the simple cataloging of living things in the world. Ecologists also became interested in understanding how living things function and how they interrelate with one another and with the environment-to explain that peculiar element that makes the Earth unique: life. We will begin by learning what ecology is and what it is not. (At times the word has been used incorrectly as a synonym for environmental protection.) Later, we will look at how living things are classified, before moving into the study of the environments in which they live: the land, water, and air.

Updated for 2013, Ecology is one title in the Britannica Illustrated Science Library Series.

"This book is unique in focusing on nonequilibrium aspects of ecology, providing evidence for nonequilibrium and equilibrium in populations (and metapopulations), in extant communities and in ecological systems over evolutionary time, including nonequilibrium due to recent and present mass extinctions. The assumption that competition is of overriding importance is central to equilibrium ecology, and much space is devoted to its discussion. As communities of some taxa appear to be shaped more by competition than others, an attempt is made to find an explanation for these differences."--Jacket

"This sixth edition of Ecology, written for undergraduate students taking their first course in ecology, provides comprehensive yet concise coverage of fundamental ecological principles, with attention to relevant issues including climate change, spread of invasive species, and pollution. The text utilizes a variety of learning tools-such as Case Studies, Connections in Nature, Climate Change Connection vignettes, Ecological Toolkit boxes, and Learning Objectives-to engage students, highlight critical information, and make real-world connections to the source material. The text is complemented by an enhanced ebook and an updated, user-friendly digital suite full of interactive activities, quizzes, videos, and layered figures to reinforce key concepts"
"Despite their often dangerous and unpredictable nature, landslides provide fascinating templates for studying how soil organisms, plants, and animals respond to such destruction. The emerging field of landslide ecology helps us to understand these responses, aiding slope stabilization and restoration and contributing to progress made in geological approaches to landslide prediction and mitigation. Summarizing the growing body of literature on the ecological consequences of landslides, this book provides a framework for the promotion of ecological tools in predicting, stabilizing, and restoring biodiversity to landslide scars at both local and landscape scales. It explores nutrient cycling; soil development; and how soil organisms disperse, colonize, and interact in what is often an inhospitable environment. Recognizing the role that these processes play in providing solutions to the problem of unstable slopes, the authors present ecological approaches as useful, economical, and resilient supplements to landslide management"--
