Influences Of Adjacent Land-Use On Avian Community Structure In Sub-Boreal Peatlands Of The Midwest, Lucas J. Wandrie
Influences Of Adjacent Land-Use On Avian Community Structure In Sub-Boreal Peatlands Of The Midwest, Lucas J. Wandrie

Surrounding land use influences avian community structure; moreover, anthropogenic manipulation of habitat can alter bird species richness and composition. In the first chapter of my thesis work, I conducted avian surveys at 20 sub-boreal peatlands in eastern Minnesota and western Wisconsin to detect correlations between land development and bird community structure. Peatlands are wetlands that accumulate decaying organic plant material (peat) and provide valuable and diverse habitats to a variety of flora and fauna. I measured urban and cropland development at three spatial scales (500 m, 1000 m, and 2500 m radii). Effects of development on avian communities also were …
The Effects Of Invasion By Reed Canarygrass (Phalaris Arundinacea) On Avian Communities And Nesting Success In Minnesota Wetlands, Emily J. Hutchins
The Effects Of Invasion By Reed Canarygrass (Phalaris Arundinacea) On Avian Communities And Nesting Success In Minnesota Wetlands, Emily J. Hutchins
All Graduate Theses, Dissertations, and Other Capstone Projects
Invasive plants are a primary contributor to loss of biodiversity worldwide. In southern Minnesota, many wetlands have been invaded by reed canarygrass (Phalaris arundinacea). The current perception among ecologists and resource managers is that these wetlands are of little value to wildlife, yet little is known about the effects on birds of the widespread conversion of diverse wetlands to apparent monocultures of P. arundinacea. The purpose of this study was to determine the effects of P. arundinaceamediated changes in the wetland plant community on avian communities and nesting success. During 2006 and 2007, I studied four diverse sedge wetlands paired …
Analysis Of The Genetic Structure Of Bithynia Tentaculata Snail Populations In Wisconsin And Minnesota, Sarah J. Whalen
Analysis Of The Genetic Structure Of Bithynia Tentaculata Snail Populations In Wisconsin And Minnesota, Sarah J. Whalen
All Graduate Theses, Dissertations, and Other Capstone Projects
In recent years, there have been tens of thousands of waterfowl mortalities in Wisconsin and Minnesota. An invasive species of snail, Bithynia tentaculata, is a host for the trematode parasites (Cyathocotyle bushiensis and Sphaeridiotrema globulus) that have caused these deaths. A microsatellite-enriched genomic library was detected using DNA from a B. tentaculata specimen from Lake Onalaska (Pool 7 of the Upper Mississippi River). Seven polymorphic microsatellite loci were used to genotype snails collected from Lake Butte des Morts, Shawano Lake, and Lake Onalaska in Wisconsin, as well as Lake Winnibigoshish in Minnesota. The genetic diversity of each population was measured …
