The Habitable Planet: A Systems Approach to Environmental Science 

Ecosystems Scientists

Content Developer

Paul R. Moorcroft
Paul Moorcroft is a professor of biology at Harvard University who specializes in terrestrial ecosystem dynamics. His research investigates how ecological processes affect the structure, composition, and functioning of terrestrial ecosystems at regional to global scales. He has published a book with Mark Lewis on animal movement, entitled Mechanistic Home Range Models: From Individual Behavior to Large-scale Pattern.

Featured Scientists

Robert H. Crabtree
Robert Crabtree is the founder and chief scientist of the Yellowstone Ecological Research Center—a unique, private, non-profit scientific organization that specializes in long-term, large-scale, collaborative ecological study in the Greater Yellowstone Area. Dr. Crabtree has lead or collaborated in more than 40 research efforts, including a variety of remote sensing applications. Trained as a quantitative ecologist, Dr. Crabtree also specializes in landscape ecology and predictive habitat attribute modeling. He is a well-known expert on predator/prey relations, and is one of the leading authorities on the far-reaching ecological effects resulting from the reintroduction of the wolf to Yellowstone National Park. //Read interview transcript


Stuart J. Davies
Stuart Davies is the director of the Center for Tropical Forest Science (CTFS) at the Smithsonian Tropical Research Institute. This program coordinates a global network of 17 large-scale tropical forest research plots in 13 countries. The goals of the CTFS program are to: (i) to monitor representative biodiverse tropical forests of the world through a network of large long-term plots; (ii) to conduct research on the origin and maintenance of diversity in tropical forests, (iii) to understand the function of tropical forests and how tropical forests and their biodiversity can best be conserved, managed, and used in sustainable ways for human benefit; and (iv) to develop opportunities in training, capacity building, education and international collaborative studies in tropical forest science. Davies received his Ph.D. from Harvard University in 1996. He is a tropical ecologist and taxonomist specializing in the plants and ecosystems of Southeast Asia. His research investigates ecological and evolutionary influences on variation in rain forest communities across the tropics. Prior to becoming the director of the CTFS, Davies coordinated the Asia Program of CTFS which is cosponsored by Harvard University. Before joining CTFS, he was a senior research associate at the Center for International Development at Harvard University (2001-2003) and associate professor at the Institute for Biodiversity and Environmental Conservation, University of Malaysia Sarawak (1997-2001). // Read interview transcript
