Ziziphus celata conservation genetics
Ziziphus celata is a federally endangered shrub species restricted to a handful of populations in the Lake Wales Ridge of central Florida. I am currently investigating the genetic properties of Ziziphus, identifying both variation in natural populations, as well as providing data for the choice of individuals in introduced populations. Additionally, I am investigating the genetic mechanism that controls self incompatibility to facilitate the production of seedlings for introductions.
With about 90 species, the genus Lomatium is endemic to western North America. Species relationships within the genus are poorly understood. I am currently working on a molecular phylogenetic analysis of the genus. Using this phylogeny, I will focus on a small group of species that contains rare and widespread species and study the evolutionary dynamics leading to specieation as well as the population genetic factors effecting commonness.
