Explore fundamental concepts in ecology, from the nature of ecosystems and the basics of ecosystem structure and function, to the complex relationships within and between species and between humans and their environment. Ecology includes a comprehensive chapter on practical ecological techniques and the design and implementation of field studies.

A fresh approach to teaching evolutionary principles at this level. Students are encouraged to explore and critically evaluate the wealth of evidence for our current understanding of evolution through a variety of engaging and thought-provoking activities. Beginnning with theories for the origin of life, Evolution builds understanding of microevolutionary processes though modeling activities and numerous historical and current case studies. Larger scale evolutionary patterns, including adaptive radiation, convergence and extinction are explained using relevant examples from around the world. The role of humans in evolutionary processes provides the final thought-provoking chapter.
