Simon Queenborough is the Musser Director of the Tropical Resources Institute, Senior Lecturer and Research Scientist in the Yale School of the Environment. Dr. Simon Queenborough is a botanical ecologist whose work focuses on how individuals, species, and communities (including humans) interact over ecological and evolutionary time. Over the past 20 years, he has spent extended periods in the field in Latin America and Europe, carrying out long-term research on plant population dynamics in old-growth tropical forests and managed arable farming communities, as well as working on theoretical models of population dynamics. Current research interests include understanding mechanisms of diversity, breeding systems and resource allocation, and quantitative methods in population dynamics. His long-term research in Yasuni National Park (Ecuador), one of the most diverse ecosystems on the planet, examines individual-level reproduction as a function of climate and local environment in a variety of tree species, from long-lived shade-tolerant trees to fast-growing pioneers. Results will help us understand the effects of climate change on tropical forests.
