Effects Of Hydrology On The Growth And Recruitment Of Stream Fish In The Eastern Broadleaf Province Of Minnesota, Eric J. Krumm
Effects Of Hydrology On The Growth And Recruitment Of Stream Fish In The Eastern Broadleaf Province Of Minnesota, Eric J. Krumm
All Graduate Theses, Dissertations, and Other Capstone Projects
Agricultural practices and urban development have altered streamflows within the Eastern Broadleaf Province of Minnesota. Stream-flow alteration can produce significant changes in native freshwater communities. Therefore, knowledge of streamflow effects on representative freshwater populations and communities within the province are needed to maintain ecological integrity. Fish community and population dynamics often display predictable responses to flow regimes, which can make fishes model organisms for examining flow-ecology relationships.
In lotic systems, annual variation in streamflow can influence the annual growth and recruitment of fishes. Understanding the growth and recruitment of fish populations is essential for management and conservation efforts. Growth can …
Development And Evaluation Of A Habitat Suitability Model For White-Tailed Deer In An Agricultural Landscape, Eric Anstedt
Development And Evaluation Of A Habitat Suitability Model For White-Tailed Deer In An Agricultural Landscape, Eric Anstedt
All Graduate Theses, Dissertations, and Other Capstone Projects
White-tailed deer (Odocoileus virginianus) are an ecological, economical, and socially significant species that occupy a variety of ecoregions. White-tailed deer are mobile habitat generalists that prefer habitats containing woody cover. Deer have successfully adapted to habitat-fragmented, agricultural landscapes. As a result, deer are not uniformly distributed across intensively cultivated areas, which make field surveys difficult with often highly variable spatial data. To increase sampling efficiency (deer observed / sampling effort), the landscape can be stratified based upon preferred habitat types. Habitat suitability models (HSI) have been used to represent hypothesized wildlife-habitat relationships, and therefore the likelihood of deer being observed …
Hydrologic And Temperature Regime Influence On Growth And Recruitment Of Fishes In An Upper Midwest Riverine Ecosystem, Brett Donald Nelson
Hydrologic And Temperature Regime Influence On Growth And Recruitment Of Fishes In An Upper Midwest Riverine Ecosystem, Brett Donald Nelson
All Graduate Theses, Dissertations, and Other Capstone Projects
The natural flow regime is often identified as the primary driver of ecological integrity in rivers. The Minnesota River basin is characterized by a row-crop agricultural landscape with an extensive network of drainage tiles and ditches to improve land productivity. Intensive surface and subsurface drainage alters flow regimes, increasing the magnitude and frequency of high flows. Changes in river hydrology lead to alterations in geomorphology, including increased bank erosion, channel widening, and downward incision that can lead to floodplain disconnection. Disruption of historical hydrology can alter energy flow and connection to specialized habitats subsequently affecting important aquatic communities and populations …
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 …
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 …
