"Identifying Unique Biotypes of Eurasian Watermilfoil Using A Genetic Fingerprinting Method"

Conference Name: Aquatic Plant Management Society (APMS) National Meeting

Aquatic plant managers increasingly recognize the role of unique biotypes that exhibit unique growth responses to management practice.  One challenge to identifying biotypes is that they are often indistinguishable from one another based on morphology.  I am exploring approaches involving the utilization of molecular markers to identify potentially unique biotypes.  Here, I present the result of a genetic survey of Eurasian watermilfoil in North America using highly polymorphic molecular markers.  This data reveals several genetically distinct populations, which may correspond to the presence of unique biotypes.  This research emphasizes the degree of genetic variation that occurs within this system and how this variation may correspond to attributes of management concern.
