Research:
Tropical forest community assembly
The role of environment in trait diversity of Ficus assemblages
See the blog I am producing for middle school students in Austin.
This is in collaboration with Dr. Tang Yong of Xishuangbanna Tropical Botanical Garden
Estimating dispersal limitation in community assembly in tropical forest tree communities
I am working on developing statistical models to test the importance of dispersal limitation and environmental limitation as processes that structure tree communities. I am using the BCI 50 ha plot dataset.
The effects of landscape structure on the movements of edge frugivores and seed rain
In eastern Amazonian rainforest fragments I am studying how spatial structure of vegetation affects the movement of avian frugivore species that forage at the edge of primary forests and in neighboring open habitats. Seed input into secondary growth can be limiting to forest succession, and the spatial distribution of frugivore dispersers is likely correlated to the spatial distribution of the seeds they deposit. This work is being conducted at the Fazenda São Marcos, near Aurora in the state of Pará. Support for this project comes from the Brazil Center and the department of Ecology Evolution and Behavior at the University of Texas at Austin, and from Tarcísio Meira, owner of Fazenda São Marcos.
Biogeography of the U.S.-Mexico border and its dispersal barriers
The border fence and border anthropogenic landscapes represent serious challenges to dispersal for many animals. I used biogeographical patterns along the border to identify species potentially threatened by 1) potential extensive border barriers in the future and 2) current border barriers. I then identified regions rich in such potentially threatened species.
The figure at right shows levels of regional species richness in a sliding window (r = 50km) across the transboundary region. Only species found along the border are considered. Blue shows the locations of pedestrian fences. Dotted lines are representative species ranges potentially divided by border barriers
This work is being conducted in collaboration with Walter Jetz.
