Common milkweed (Asclepias syriaca) and the Anthropocene: Insights from population genetics and common garden experiments.

Agricultural expansion over the past 200 years has dramatically altered our planet. Disturbed agricultural fields have been the devil for some plants and a paradise for others. In his influential 1982 work, “On the Origin of the Field Plants of the Northeastern United States”,  Prof. Peter Marks addresses the question - ‘In the primeval landscape, where were the plants that are abundant today in old fields?’ In this current study, we seek to provide more insight into this question by using common milkweed, Asclepias syriaca, as a model system.  Through a combination of detailed population genetic analyses, common garden experiments, and herbaria data mining, this study attempts to reconstruct population trends and understand phylogeography of ecologically relevant variation in common milkweed.  This study provides insight into how human-mediated changes to the natural ecosystem may impact the botanical world.
