Every plant, microorganism, and animal on Earth exists within an ecosystem: a complex network of interdependent relationships in which each individual strand is important and contributes to the success of the whole. Ecosystems, in turn, interact with one another to form the biosphere: the zone of life on our planet.

But these systems, so important to the world around us, are far from stable. Instead, ecosystems are constantly changed by the pressures of biological, geological, and physical forces. In addition, the rapid growth of human populations and their attendant technologies has created unprecedented forces of ecological change. Only when you look beyond the individual level and observe how populations of different species interact with themselves, with other species, and with their physical environment, as well as how they respond and adapt to change, can you fully understand how life truly works.

Now, with Earth at the Crossroads: Understanding the Ecology of a Changing Planet, you can explore the rich interconnections that make up the great and fascinating web of life on Earth. In this compelling 36-lecture course, behavioral ecologist Eric G. Strauss of Boston College provides you with a comprehensive overview that is a hallmark of the study of ecology. With Professor Strauss as your guide, you'll investigate the remarkably complex workings of Earth's biosphere and learn about the myriad forces that shape the world's habitats, from the movement of water and nutrients within an ecosystem to the reproductive strategies employed by plants and animals around the world.

As you delve into the biosphere's intricate network of relationships, you develop a deeper appreciation of the rich complexity of the life around you. You'll also strengthen your understanding of some of the most important debates in current affairs, including questions of climate change, protection of endangered species, and alternative energy sources. Earth at the Crossroads exposes you to the science behind these debates, allowing you to develop your own opinions and back them up with the latest scientific evidence.

Professor Eric G. Strauss is a Research Associate Professor of Biology and the director of the Environmental Studies Program at Boston College, as well as a science adviser for the Urban Ecology Institute. He received his Ph.D. from Tufts University. His research focuses on behavioral ecology and science education. He is editor in chief of the Web-based journal Cities and the Environment and senior author of the textbook Biology: The Web of Life.
