The Effects Of Dormant Season Burning And Flooding On Invasive Cattail, Typha X Glauca, On Rainy Lake And Lake Kabetogama In Northern Minnesota, Erika Meints Aug 2023

The Effects Of Dormant Season Burning And Flooding On Invasive Cattail, Typha X Glauca, On Rainy Lake And Lake Kabetogama In Northern Minnesota, Erika Meints

All NMU Master's Theses

Typha x glauca is one of the most invasive plants in North America. The plant exhibits hybrid vigor and displaces native flora by rapidly forming dense monotypic stands that can break free from the substrate and form floating mat types when established. I tested the effects of prescribed burning, on Typha x glauca in wetlands to adjacent large lakes in Voyageurs National Park in northern Minnesota. My team surveyed four wetlands that were burned in late winter of 2020-21, and six that were unburned controls. Pre-burn data was also collected for all ten wetlands. Pre-flooding data from other wetlands within …

Understanding Neglect Of Plant Biology Education In Michigan Middle Schools, Kim Smith May 2019

Understanding Neglect Of Plant Biology Education In Michigan Middle Schools, Kim Smith

All NMU Master's Theses

The purpose of this study was to identify historical trends of neglect in plant biology education, their continuation today in Michigan middle school classrooms, and to uncover reasons for this neglect. A content analysis of state and national science standards and an online survey of Michigan middle school life science teachers were conducted. Findings showed a trend of increasing references in national standards from animals or plants to general organisms, as well as a decrease in the overall number of specific references in the standards. The data also revealed that nearly half of the teachers surveyed spent less than ten …


Ecological Drivers Of Plant Community Composition In A Patterned Fen At Seney National Wildlife Refuge, Michigan, Alex Graeff Aug 2018

Ecological Drivers Of Plant Community Composition In A Patterned Fen At Seney National Wildlife Refuge, Michigan, Alex Graeff

All NMU Master's Theses

Regional variation in geomorphology, vegetation, fen landforms, and water chemistry create a variety of unique peatlands across the Northern Hemisphere. In the Great Lakes region, patterned fens have been extensively studied in northern Minnesota, but largely ignored in Michigan. The purpose of this study was to describe vegetation, landforms, and water chemistry in a patterned fen at Seney National Wildlife Refuge. Percent cover of plant species and environmental variables were measured at 298 relevé style plots across 6 landform types: triangular swamp forests, featureless water tracks, peripheral water tracks, strings, flarks, and ponded sedge lawns. Additionally, several morphometric parameters were …
