Headshot of Mary Peacock.


I have an active research program in Conservation Science with an emphasis in Conservation Genetics. I am especially interested in the how organisms assort themselves on the landscape and the effect of habitat fragmentation on population dynamics. This general interest acts as an umbrella for a variety of research projects that range from basic research on metapopulation dynamics for variety of organisms including pikas (Ochotona princeps) and toads (Bufo boreas) to viability modeling of Lahontan cutthroat trout (Oncorhynchus clarki henshawi) populations in both fragmented and non-fragmented systems. I use a variety of research tools to address these questions including molecular genetic techniques, population viability modeling, and traditional behavioral ecology methods. I have used a combination of mark-recapture and genetic methods, to examine mating and dispersal patterns, population genetic structure and the maintenance (or loss) of genetic variation in spatially heterogeneous habitats. I also use phylogeographic and phylogenetic approaches to species conservation issues.
