Woody plant encroachment into grasslands:  Impacts on the 3-dimensional spatial patterns of soil biogeochemical processes

My research is aimed at understanding how woody plant invasion into grasslands alters the 3-dimensional spatial patterns of soil biogeochemical processes. To accomplish this, I am taking spatially-specific soil samples to a depth of 1.2 meters across a landscape in southern Texas where woody plants have been encroaching into grasslands for the past century. My research objectives are to: (1) quantify changes in spatial patterns of soil carbon and nitrogen storage with increasing soil depth; (2) investigate spatial patterns of δ15N with soil depth to understand how nitrogen cycling processes are altered by woody invasion; (3) reconstruct vegetation dynamics by linking spatial patterns of δ13C across soil depths with sequential aerial photographs; (4) examine the flexibility of soil stoichiometry in response to grassland-to-woodland conversion at the landscape scale.
