Comparisons Of Genetic Diversity Among Disjunct Populations Of Magnolia Tripetala, Victoria A. Gilkison
Mahurin Honors College Capstone Experience/Thesis Projects
Plant ranges are often made up of core areas where the distribution is continuous and the population density is high with small disjunct populations at the margins of the core. One well-studied type of disjunct population is formed by long distance dispersal as plants migrate away from disjunct Pleistocene refugial populations. The retreat of the Wisconsinan glaciation resulted in the outward dispersal of many plant species from their refugial locations to areas with suitable habitat. Many plants expanded their ranges through rare-long-distance dispersal.
This study used microsatellites to compare the genetic diversity, inbreeding levels, and gene flow frequency of disjunct …
