Minnesota AIS Detectors  will be hosting Minnesota Aquatic Invasive Species Research Center graduate student, Carli Wagner, during this FREE webinar to discuss her recent research on one of Minnesota’s newest (and least understood) aquatic invasive species, starry stonewort. Read more about her talk below.

“The invasive alga starry stonewort (Nitellopsis obtusa) has become an increasing problem in Minnesota lakes since it was first identified here in 2015. In several lakes, starry stonewort is widely established and can grow abundant and dense. This growth certainly has recreational impacts, but the ecological effects of starry stonewort in Minnesota lakes are unknown. Potential impacts to native aquatic plants are of particular concern since they are an integral part of lake ecosystems.

I examined the impacts of starry stonewort on native aquatic plants and tracked its invasion over multiple years to assess how it spreads and changes habitat. I found that starry stonewort negatively affected multiple aspects of native aquatic plant communities – from individual species to functional groups to overall diversity and abundance. Starry stonewort can quickly expand and alter plant communities as a result. These findings fill knowledge gaps related to the impacts of starry stonewort in Minnesota lakes and can be used to guide response efforts.”
