Vegetation Surveys In Southern Minnesota Prairies: Management, Invasive Species And Future Directions, Ainsley Peterson
Vegetation Surveys In Southern Minnesota Prairies: Management, Invasive Species And Future Directions, Ainsley Peterson
All Graduate Theses, Dissertations, and Other Capstone Projects
This paper is formatted into two chapters: a general introduction on prairies, management, and this study (Chapter 1), and the study formatted for submission to a journal for publication (Chapter 2). To manage habitat loss in Southern Minnesota prairies, and subsequent ecological damage, private and public individuals have responded with restoration. This study investigated the use of an accepted vegetation monitoring tool to survey prairies (N=31) in Southern Minnesota during June/July (2019), targeting peak growing season to see whether restored prairies had lower invasive species richness, and relatively greater native richness. We hypothesized that restored prairies would have higher species …
Zebra Mussel (Dreissena Polymorpha) Habitat Associations In Four West-Central Minnesota Lakes, April Rose Londo
Zebra Mussel (Dreissena Polymorpha) Habitat Associations In Four West-Central Minnesota Lakes, April Rose Londo
All Graduate Theses, Dissertations, and Other Capstone Projects
In 1989, zebra mussels (Dreissena polymorpha) were first documented in the land of ten thousand lakes in the Lake Superior Basin at Duluth. Zebra mussels are successful invaders because the species attaches to substrates with byssal threads, can adapt to a wide range of environmental conditions, and has a free-swimming veligers that are easily transported. Although invasive mollusks pose a range of economic and ecological threats to inland waters, our understanding of zebra mussels in Minnesota lakes remains limited. To gain additional information regarding zebra mussel ecology in lake systems, I conducted research in four west-central Minnesota lakes that were …
Communication Effectiveness And The Emerald Ash Borer Mitigation Campaign, Jonathon Heide
Communication Effectiveness And The Emerald Ash Borer Mitigation Campaign, Jonathon Heide
All Graduate Theses, Dissertations, and Other Capstone Projects
Environmental risk communication is scrutinized by several research fields including, as Herndl and Brown (1996) show, technical communications. This technical communications thesis rhetorically analyses how large and small government agencies in the State of Minnesota communicate a specific environmental risk: emerald ash borer (EAB). EAB is an insect native to Asia and arrived in Detroit on a cargo ship sometime in the 1990s (Cappaert 2005, 153; Poland 2011, 46). By 2012, it spread to the 15 states and two Canadian provinces (USDA--APHIS 2012). EAB's life cycle will causes tree decline in Minnesota, the state with the most ash (MNDNR 2012). …
