Robert E Ricklefs - Curators' Professor of Biology at the University of Missouri-St. Louis, where he has been a member of the faculty since 1995. His teaching at Missouri, and previously at the University of Pennsylvania, has included courses in introductory and advanced ecology, biogeography, evolution, and biological statistics. Bob's research has addressed a broad range of topics in ecology and evolutionary biology, from the adaptive significance of life-history traits of birds, to island biogeography and the community relationships of birds, herbivorous insects, and forest trees.
Rick Relyea - the Director of the Darrin Fresh Water Institute at Rensselaer Polytechnic Institute. He also serves as Director of the Jefferson Project at Lake George, a groundbreaking partnership between Rensselaer, IBM, and the FUND for Lake George. For the project, Relyea leads a team of Rensselaer scientists, engineers, computer scientists, and artists who are using the latest in science and technology to understand, predict, and enable a resilient ecosystem for nearby Lake George.

Now in its eighth edition, this landmark textbook has helped to define introductory ecology courses for over four decades. With a dramatic transformation from previous editions, this text helps lecturers embrace the challenges and opportunities of teaching ecology in a contemporary lecture hall. 
The text maintains its signature evolutionary perspective and emphasis on the quantitative aspects of the field, but it has been completely rewritten for today's undergraduates. Modernised in a new streamlined format, from 27 to 23 chapters, it is manageable now for a one-term course. Chapters are organised around four to six key concepts that are repeated as major headings and repeated again in streamlined summaries. Ecology: The Economy of Nature is available with SaplingPlus. An online solution that combines an e-book of the text, Ricklefs' powerful multimedia resources, and the robust problem bank of Sapling Learning. Every problem entered by a student will be answered with targeted feedback, allowing your students to learn with every question they answer.
