Effects Of Hydrology On The Growth And Recruitment Of Stream Fish In The Eastern Broadleaf Province Of Minnesota, Eric J. Krumm Jan 2016

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 …

All Graduate Theses, Dissertations, and Other Capstone Projects

My thesis show opened on Friday, March 11, 2016 at the 410 project's art gallery, located in downtown Mankato.

The artwork consisted of sculptures displayed on pedestals, hanging on the walls, sitting on specifically constructed arrangements, and hanging from the ceiling. The materials I used to create these sculptures have a dramatically contrasting appearance, but have one universal similarity. At some point most of the materials used were liquid or fluid. I used metals, ceramics, hand blown glass, plastics, and wax. I like to work with these materials in that fluid state because of the added flexibility and forgiveness they …


Development And Evaluation Of A Habitat Suitability Model For White-Tailed Deer In An Agricultural Landscape, Eric Anstedt Jan 2016

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 …


A Measure Theoretic Approach To Problems Of Number Theory With Applications To The Proof Of The Prime Number Theorem, Russell Lee Jahn Jan 2016

A Measure Theoretic Approach To Problems Of Number Theory With Applications To The Proof Of The Prime Number Theorem, Russell Lee Jahn

All Graduate Theses, Dissertations, and Other Capstone Projects

In this paper we demonstrate how the principles of measure theory can be applied effectively to problems of number theory. Initially, necessary concepts from number theory will be presented. Next, we state standard concepts and results from measure theory to which we will need to refer. We then develop our repertoire of measure theoretic machinery by constructing the needed measures and defining a generalized version of the multiplicative convolution of measures. A suitable integration by parts formula, one that is general enough to handle various combinations of measures, will then be derived. At this juncture we will be ready to …


Early Detection Of Mountain Pine Beetle Damage In Ponderosa Pine Forests Of The Black Hills Using Hyperspectral And Worldview-2 Data, Kyle Edward Mullen Jan 2016

Early Detection Of Mountain Pine Beetle Damage In Ponderosa Pine Forests Of The Black Hills Using Hyperspectral And Worldview-2 Data, Kyle Edward Mullen

All Graduate Theses, Dissertations, and Other Capstone Projects

A leading cause for mortality in the pine forests of western North America, the mountain pine beetle, has impacted over 400,000 acres of ponderosa pine forest in the Black Hills of South Dakota since 1996. Methods aimed at earlier detection, prior to visual manifestation of a mountain pine beetle damage in the tree crown, have not been successful because of the overlap and variability of spectral response between the initial stages of attack (green-attacked) and non-attacked tree crowns. Needle-level reflectance spectra was measured from green-attack and non-attack ponderosa pine trees in early spring following an infestation and analyzed using a …


Land Cover Mapping And Change Analysis At The Tensleep Preserve In Wyoming, Tyler Richard Grupa Jan 2016

Land Cover Mapping And Change Analysis At The Tensleep Preserve In Wyoming, Tyler Richard Grupa

All Graduate Theses, Dissertations, and Other Capstone Projects

Mapping land cover and land cover change are important, especially for land managers who protect natural lands and generate restoration projects. Accurate land cover assessment of rangelands can be difficult because the spectral difference between plant species may be minimal. The goal of this research is to map the land cover in the Tensleep Preserve and highlight change that has occurred over the past twenty-three years using the Feature Analyst extension. The land cover change map will highlight significant changes and Feature Analyst will accurately identify different land covers using historical aerial photographs and ground truthing data collected in 2013. …


Cleaning Up Minnesota's Archeological Record With Maid: The Minnesota Archeological Integrated Database, Andrew Allen Brown Jan 2016

Cleaning Up Minnesota's Archeological Record With Maid: The Minnesota Archeological Integrated Database, Andrew Allen Brown

All Graduate Theses, Dissertations, and Other Capstone Projects

Minnesota archeologists face many difficulties in conducting archeological research and managing the state's cultural resources such as a lack of standardized data formats and field/lab procedures, a lack of a centralized data repository, and insufficient existing databases. The purpose of this thesis is to build the foundation for a database system that addresses these difficulties along with being efficient and effective for entering, managing, and analyzing archeological data produced in the field and in the lab. The Minnesota Archeological Integrated Database is being built to be a long-lasting, constantly evolving system to be used by archeologists and cultural resource managers …
