“I received my Ph.D. in Wildlife Science and Mathematics from Texas Tech University under the primary direction of Loren M. Smith.  We examined the effects of agricultural land use (i.e., grassland vs. cultivation) and landscape structure (i.e., patch juxtaposition, geometric complexity) on postmetamorphic body size and population demographics of amphibians using playa wetlands in the Southern High Plains (SHP).  I also investigated with Linda J. S. Allen (Biomathematics Research Group) the presence of biological chaos in Southern High Plains amphibian populations.  Ultimately, we discerned potential regulating mechanisms (i.e., density dependence, environmental stochasticity) in SHP amphibian populations via modeling with deterministic and stochastic nonlinear difference equations.”
