Aaron Comeault M.Sc. student
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 working on the poison frog Dendrobates tinctorius. Dendrobates tictorius is a Neotropical anuran endemic to the Guiana Shield that exhibits extreme interpopulation variation in aposematic coloration. We are currently looking at how the selective pressures of predation and assortative mating within populations can act as barriers to gene flow. By interpreting the results of predator selection and mate choice experiments in relation to phylogeographic and population genetic data we can move towards a greater understanding of how selective forces act to produce and maintain interpopulation variation and drive the process of speciation.


Nicole Davison M.Sc. student
Nicole's research focuses on the distribution and speciation of an ant species in Madagascar. She is interested in the phylogeography/biogeography and conservation of these species and is using molecular techniques (anonymous nuclear loci) to examine patterns of divergence and relate these to climatic history and landscape features.


Stuart Nielsen Ph.D. 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.).
