Students may think of ecologists as people who pick up trash and protest for a cleaner environment. In this book, the term ecologist is used to refer to scientists who study ecology—the study of relationships among organisms and between organisms and their physical environment. Through the readings, exercises, protocols, and research projects students will learn not only about important ecological concepts, but also about how ecologists conduct research. They will also learn how ecological science and research can be applied to solving a real-life environmental problem—the control of invasive species. This free selection also includes Inquiry and Ecology, Table of Contents, and Introduction.
