BioS. Joseph Wright is Senior Scientist at the Smithsonian Tropical Research Institute in Panama. He received his B.A. from Princeton University (1974) and his Ph.D. from the University of California at Los Angeles (1980). He has published more than 200 peer-reviewed articles, which have been cited more than 12,000 times. He served as President of the Association for Tropical Biology and Conservation. His research interests include forest ecology, plant phenology and conservation biology. He developed protocols to study flower and seed production and seedling biology that have been replicated in 14 forests in eight tropical countries. His work on the future of tropical forests concerns nutrient deposition, global atmospheric and climate change, the consequences of overhunting (the ‘bushmeat crisis’) for plant species composition, the second chance abandoned lands and secondary forests present for tropical conservation, and evidence for successful strategies for the conservation of tropical forests. A full list of publications is available.
