Colin A. Chapman has conducted fieldwork in the Caribbean, Costa Rica, and now has established a long-term research program in Kibale National Park, Uganda. Trained in both anthropology and zoology, his research focuses on how the environment influences primates and how primates influence their environment (herbivory, seed dispersal). Given the current plight of primates that he has witnessed around the world, his research attempts to understand what determines the abundance of primates in a variety of natural and human-modified settings and the impact of primate loss.
Born and raised in northern Brazil, Carlos Peres has conducted fieldwork on forest primates and other vertebrates throughout the Atlantic forest and all major river basins of Amazonia, including the largest standardized program of line-transect censuses in any tropical forest region. He is co-director of two field stations in Brazilian Amazonia and is currently assisting in the design and implementation of a major network of Amazonian nature reserves. In 1995, he received a Bay Foundation Award for his research contribution to tropical ecology and leadership in biodiversity conservation, and in 1999 was named an environmentalist “Leader for the New Millennium” by Time magazine. He divides his time between fieldwork in Brazil and the School of Environmental Sciences, University of East Anglia, UK.
