Current projects include comparative phylogeography, particularly of vertebrates in the western US, phylogenetics of various reptile lineages, population genetics of several local vertebrate species to establish population connectivity and adaptive potential, coevolution between garter snakes and newts, speciation and isolating mechanisms in several local reptile species, assessing biogeographic “rules” in vertebrates, and examining patterns of morphological and molecular w88 sports betting app and their underlying causes.

Evolution, w88 sports betting app and Conservation Biology of Reptiles and Amphibians

We are interested in a broad array of evolutionary, ecological, and w88 sports betting app topics, primarily in reptiles and amphibians, ranging from simple questions of diet differences between sympatric lizards, to patterns of molecular evolution in specific snake proteins. In general, our research program combines traditional field studies (i.e. collection of specimens and associated data in the wild) with emerging molecular genetic techniques (i.e. DNA sequence data, DNA fragment data, gene expression data) to address fundamental questions in these vertebrate systems. We typically analyze these data in a phylogenetic framework which allows inferences about patterns of adaptive change, molecular evolution, fluctuations in population structure through time, and can even identify unique evolutionary lineages worthy of w88 sports betting app attention.
