I'm interested in a broad-range of topics, including land-use change, habitat fragmentation, biodiversity monitoring and practically anything involving camera-trapping and-or mammals. I've spent a lot of my time trying to understand how species and communities are affected by human-impacts, in particular in the tropics. Two examples of this are: 1) predicting the number of "living dead" species hanging on in Amazonia, and 2) looking at what patterns of beta-diversity tell us about how we should design conservation set-aside.
Advancing Research on Tropical Time Trends (ART3).
Over the last two decades, technology has played an ever increasing role in ecology and conservation. Thousands of sensors have been deployed in the field over this period, collecting verifiable and systematic data on the locations and activities of species. We are now in a position to use these datasets to examine, for the first time, how species and ecosystems are faring over time in an ever-changing world.
This project will integrate historical camera trap data, remote-sensing data and cutting-edge statistical models to uncover temporal trends in Southeast Asian mammals, a highly threatened group of species. Many mammal species in the region depend on small protected areas and-or fragmented landscapes for their persistence, and we will examine whether such habitats are indeed effective for mammal conservation. This work will inform protected area policy and management, as well as guidelines for sustainability schemes (such as RSPO, FSC and High Carbon Stock).
