Population Genetic Structure Of Asclepias Tuberosa In Northwest Iowa: A Comparison Within And Between Remnant Prairies And Commercially Available Seed, Jeffrey T. Ploegstra, Brittany De Ruyter, Tony Jelsma

Journal of the Iowa Academy of Science: JIAS

Isolated in scattered remnants, less than 0.1% of Iowa’s original tallgrass prairie remains. The small populations remaining are at risk for reduced genetic diversity, inbreeding depression, and outbreeding depression. In light of these concerns, we used microsatellite analysis to assess the genetic structure of butterfly milkweed (Asclepias tuberosa) populations on prairie remnants in northwest Iowa. We compared remnant populations with a restoration population at Dordt College in Sioux Center, Iowa, and with an Oklahoma seed source. Microsatellites identified for use in common milkweed (Asclepias syriaca) had sufficient polymorphism information content (PIC) across the butterfly milkweed ( …
