Biodiversity-ecosystem functioning, global change biology, terrestrial-aquatic linkages

---------------------------------------------

I am broadly interested in exploring the functional implications of biodiversity loss and global environmental change in terrestrial and aquatic ecosystems.  

My research has focused on the indirect effects of elevated atmospheric CO2 and human land-use on aquatic ecosystems, as well as the importance of resource and consumer diversity in determining organic matter processing in terrestrial and aquatic ecosystems. 

I am currently investigating: 1) how changes in riparian forest composition influence stream biodiversity, and resource-consumer dynamics; 2) scaling consumer (top-down) influences on decomposition, primary production, and metabolism; 3) how variation in stream water nutrient ratios (N:P) differentially alters food web structure and metabolism; 4) the influence of drought on Southwestern and Southeastern US freshwater ecosystems.

Please contact me with research interests.
