Population Genetics

Small, Amy [1], Hanes, Margaret [2].

Inferring population structure and mechanisms of population differentiation in the carnivorous Pitcher Plant, Sarracenia purpurea, throughout Michigan.

Numerous complex historical and biological processes have likely contributed to the evolution of Pitcher Plants in the genus Sarracenia (Sarraceniaceae). Previous work in S. alata suggests that rivers and changes in population size play an important role in population diversification. Work here aims to summarize population genetic variation in S. purpurea throughout Michigan and to identify population demographic models responsible for variation throughout the Lower and Upper Peninsulas. To address these questions we analyzed sequence data from 10 nuclear, anonymous, and variable loci developed from a next-generation sequencing project. Bayesian clustering was used to discover population structure in 35 individuals across 7 populations throughout the state and a population tree was estimated in *BEAST. This study brings us closer to identifying the processes that promote speciation in North American Pitcher Plants and whether similar processes are at play throughout the genus.
