Impact of human activities on ecosystem functioning
Identifying cost-effective solutions to halt biodiversity loss
- I am interested in finding cost-effective opportunities for biodiversity conservation and do so by focusing at the nexus of biodiversity values and economic costs. In particular, I have worked on the potential for ecosystem services, such as pollination services to crops and other payments for ecosystem services (e.g., carbon-based ones such as REDD+) to offset the opportunity costs of agriculture development and thus support conservation. My work in this area has been primarily carried out in India and Brazil.
Hummingbird functional roles along a latitudinal gradient
Understanding the consequences of species loss for the functional capabilities of ecosystems is critical given on-going global change. The role a species plays in a community has been demonstrated to be dynamic and dependent on species composition. However, what remains unresolved is how species diversity modulates these dynamic functional roles and what the consequences are at the community level. To fill this gap, this project is currently evaluating structural changes in plant-hummingbird interaction networks within communities harboring resident and migratory hummingbird species along a latitudinal gradient of increasing species diversity from central Mexico to Alaska. The project will survey plant and hummingbird communities in the presence and absence of the migratory species to evaluate changes in species functional roles and community structure.
