Lewis University students Erin Cox and Kaitlyn Curtis presented a poster entitled, “Changing Patterns in Attachment as Dreissena Populations Mix” at the 106th Annual Meeting of the Illinois State Academy of Science recently held at Governors State University.
The students were studying the attachment of the two invasive species, which physically and chemically alter submerged surfaces in North American fresh waters. They used slides placed in the Milwaukee Harbor of Lake Michigan to collect samples over a four-week periods and then compared how many attached larvae of Dreissena polymorpha (zebra mussel) and Dreissena bugensis (quagga mussel) were present among the different treatments.
Previous research demonstrated that surfaces covered with biofilms had a greater number of zebra mussel postveliger larvae than initially clean surfaces. However, with quagga mussels among the Dreissena populations, the trend is no longer present.
“This research provides greater insight on the environmental cues these organisms use to decide where to attach,” Dr. Jerry Kavouras, chair and associate professor of biology at Lewis University, said. He served as a faculty mentor for the project.
The research was funded by the Lewis University Caterpillar Scholar Award, which provides an award up to $6,000 for research or scholarly work for one academic year in the areas of science, technology, engineering and math (STEM).
