Surveying Eastern Hemlocks In The Northwestern Portion Of Port Sheldon Natural Area For Hemlock Woolly Adelgid, Murielle A. Garbarino
Honors Projects
Hemlock woolly adelgid (Adelges tsugae, HWA) is an insect native to Asia that feeds on the starches of hemlock trees (Tsuga spp.). HWA is invasive to the Eastern United States and can kill Eastern hemlock trees (Tsuga canadensis). Eastern hemlock is the only hemlock species native to Michigan. As of 2019, the invasion of HWA in Michigan is concentrated in the western portion of the lower peninsula. Monitoring is important to determine the extent of HWA within the state and to establish infested areas in need of treatment. This purpose of this project was to do a 100 percent survey …

Questions: Restoring native-dominated plant communities often requires controlling invasive species, reintroducing native species, and implementing continued management practices. Can single herbicide applications to control Centaurea stoebe L. encourage establishment of seeded native species more effectively than a single mowing? Can annual hand pulling to control C. stoebe favor the persistence of seeded native species? Can mid-spring burning reduce C. stoebe and increase native forbs and grasses? After eight years, will the restored plant communities differ from those in untreated areas?
Location: Bass River Recreation Area, Ottawa County, MI, USA.
Methods: We studied the effects of site preparation (mowing, clopyralid, glyphosate), …

The recent establishment of the round goby (Neogobius melanostomus), an invasive fish in Lake Michigan, provides a model system to view fine scale evolutionary and ecological processes that can create genetic structure within a population. We used seven nuclear polymorphic microsatellite markers (N = 11-17 per site) and measurements of fish total length, weight, and sex (N = 20-74 per site) on round gobies captured by minnow traps and angling among 12 sites around the entire shore of Lake Michigan to determine if evolutionary processes are present in Lake Michigan by characterizing population structure of the round goby. Specific objectives …
