Resolving the Phylogeny and Understanding the Molecular Evolution of Rapidly Diversifying South American Pitcher Plants Heliamphora(Sarraceniaceae).

The carnivorous pitcher plant family Sarraceniaceae consists of three genera of pitcher plants that show dramatic differences in distribution: Darlingtonia restricted to disjunct populations in the northwestern US, Sarracenia with a large distribution in the eastern North America, and Heliamphorawith the highest species richness and most restricted distributions in the Guiana Highland. Recent geologic processes, such as weathering and erosion, have possibly fragmented the continuous highland habitat of Heliamphora, resulting in rapid diversification possibly due to allopatric speciation. This poster explains my research plan that aims to construct a phylogeny of Heliamphora in order to understand the family’s historical biogeography, allowing us to infer possible ecological and evolutionary processes that might have resulted in each species’ present-day distributions. Secondly, I plan to use RNA sequencing to identify genes related to carnivory and how they evolved from their non-carnivorous ancestors.
