Tim Colston PhD student (website)
Tim is interested in phylogeography/biogeography and conservation of reptiles and amphibians. He is particularly interested in the use of phylogenies to answer ecological and evolutionary questions. Tim employs a multi-disciplinary approach, using phylogeny and GIS-based methods to explore macro-evolutionary questions. For his thesis research Tim investigated the spatial and temporal components that have shaped South American reptile diversity using a widely-distribued species, Corallus hortulanus, to test several biogeographic hypotheses. In addition Tim conducted a molecular review of the genus Corallus using both ML and Bayesian approaches. In conjunction with continued investigation of biogeographic patterns of reptiles and amphibians in the Neotropics, Tim is exploring patterns of community assembly using molecular approaches.


Jason Jackson M.Sc. student
Jason is interested in the biogeography of islands, particularly, using phylogenetic methods to explore island colonization, diversification, speciation, and population structure. Jason is also interested in tracking the population structure of colonizing or invading organisms as well as the effects on native species affected by these events.


JP Lawrence PhD student
JP is primarily interested in how ecology dictates the evolution of tropical species (particularly amphibians and reptiles). For his masters, he examined ecological factors driving population size in the Strawberry Poison Dart Frog (Oophaga pumilio). For his dissertation, he will examine what mechanisms can drive and maintain the polymorphism seen in the Dyeing Poison Dart Frog (Dendrobates tinctorius). He will take a multidisciplinary approach using ecology, phylogenetics, and behavioral studies to better elucidate how polymorphism can arise and be maintained in an aposematic vertebrate. His research should aid in understanding how novel aposematic forms can arise and persist in a population.


Stuart Nielsen PhD student
Stu is interested in the alpha-level systematics, biogeography/phylogeography and conservation of Gondwanan reptile and amphibian radiations. His work primarily revolves around one of the basal gekkotan families, Diplodactylidae, found in New Zealand, New Caledonia and Australia, although he is also opening collaborations to work on endemic New Zealand frogs (Leiopelma). After species-level resolution for groups are acquired, Stu would like to use niche modeling and other such methods to explain past and present geographical distributions and how speciation was affected by various geological events through time (e.g. climate change, volcanism, tectonics, glaciations, etc.).


Dustin D. Rhodes PhD/MS (to be determined) student
Dusty is broadly interested in population genetics and phylogeography and is exploring project options with the ratsnake genus Bogertophis.


Andrew Snyder PhD/MS (to be determined) student
Andrew is broadly interested in population genetics and phylogeography and is exploring project options that compliment his field program in Guyana.


Alumni



Aaron Comeault M.Sc. 2010
Aaron's research focuses on the description of selective pressures acting on populations and the effect that these pressures have on the genetic structure or gene flow which exists between those populations.
Currently Aaron is pursuing his PhD in the lab of Patrick Nosil at the University of Colorado at Boulder.


Ken Sterling M.Sc. 2011
Ken examined the population structure of the Mississippi endemic Yazoo Darter throught it's native range. The first chapter of his thesis is currently in review at Conservation Genetics and the next two chapters will be submitted soon! Ken is currently a Ph.D. student at Utah State University in the lab of Karen Beard studying invasive bark beetles.


Nicole Davison M.Sc. 2011
Nicole's research focused on the distribution and speciation of an ant species in Madagascar. She is presently an instructor in the Biology Department at the University of Mississippi.


Drew Hataway Ph.D. 2011
Drew studied the population genetics of a dune inhabiting species of wolf spider endemic to the northern Gulf Coast, Arctosa sanctarosae. His research focused on the impacts of habitat fragmentation and the impact of this population structure on post-hurricane recovery. Drew is now an Assistant Professor at Samford University.
