Background:

Hello!

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.

I received my M.S. in Wildlife Ecology and Statistics from Mississippi State University under the primary guidance of Richard M. Kaminski. We evaluated effects of natural and man-induced wetland management techniques in moist-soil wetlands and hardwood bottomlands via 3 experiments at Noxubee National Wildlife Refuge, Mississippi. Specifically, we tested effects of autumn mowing, disking, and tilling on aquatic invertebrate and moist-soil plant responses. We also evaluated methods to predict seed yield of wetland plants using linear models. Finally, we evaluated influences of 2 winter flood regimes (periodic vs. continuous) in hardwood bottomlands on survival of oak seedlings.

During the interim (1996-98) between my M.S. and Ph.D., I worked as a Visiting Research Scientist for the Mississippi Cooperative Fish and Wildlife Research Unit with Francisco J. Vilella. We conducted an ecological assessment, and wrote a comprehensive conservation and management plan for the Puerto Rico Department of Natural and Environmental Resources (DNER). Subsequently, we consulted the Puerto Rico DNER in the development of the first moist-soil management complex in the Caribbean on the Humacao Wildlife Refuge. I also have instructed (2002-2004) Introductory Statistics and Calculus in the Department of Mathematics and Statistics at Texas Tech University, and did a short post-doc in ecology with Drs. Nancy McIntyre and Mike Willig in the Department of Biological Sciences at Texas Tech prior to starting my position at UT-Knoxville. While in biology at Texas Tech, I taught Principles of Ecology.
