Vernal pool plant metagenomics

Quantifying biological diversity in vernal pool plant communities has typically relied on traditional observational approaches, which can be problematic for a variety of reasons i.e., cost, logistics, required expertise. In addition, the complex spatial heterogeneity, rapid seasonal change, and unpredictable  variation in annual climate that is inherent to the system make detecting individual plant species presence and understanding ecological patterns of plant communities extremely complicated.

Thus, I use complementary eDNA metabarcoding and visually-based plant survey approaches, as well as experimentation to better understand ecological patterns and biogeographical effects that might shape diversity in vernal pool plant communities.
