Adriana Lopez Villalobos, PhD student
Adriana hails from Mexico City, where she completed a BSC and MSc at UNAM. Making her way north, she turned her attention from pollination ecology to the ecology and evolution of range limits, with a particular interest in the extent to which variation in demography across species’ ranges influences population genetic structure and, in turn, the adaptive potential of populations across the range. Her project involves very large-scale surveys of demographic variables and genetic structure in the Pacific coastal dune endemic Camissoniopsis cheiranthifolia. By surveying a very high proportion of extant populations distributed along the near 1-dimensional geographic range of this species, Adriana is applying population and landscape-genetic analyses to test theoretical predictions concerning how demography and geographic location combine to determine the genetic diversity within populations and the degree of differentiation and gene flow between them. Adriana is also using population-genetic and phylogeographic analyses to shed light on the evolutionary history of mating system differentiation in C. cheiranthifolia. This species exhibits the full range of mating systems: from strict self-incompatibility associated with large flowers and complete outcrossing, to fully self-compatible, cleistogamous flowers and obligate self-fertilization. Adriana’s preliminary results suggests multiple independent origins of self-fertilization within this single species as well as hybridization associated with the maintenance of self-incompatibility.
