Sustainability Of Western Kentucky University: An Examination Of Campus Environmental Policies, Performance And Potential For Change, Christian Ryan-Downing
Sustainability Of Western Kentucky University: An Examination Of Campus Environmental Policies, Performance And Potential For Change, Christian Ryan-Downing
Masters Theses & Specialist Projects
Institutions of higher learning are in a pivotal position to address the environmental problems that global society faces now, but response to this challenge requires transformation in priorities and practices. Recognizing the impacts that universities have on the environment and the social and economic costs associated with these impacts, institutions of higher learning are changing policies and management to become more sustainable. Sustainability is defined by the World Commission on Environment and Development as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs" (1987). To evaluate the environmental impacts …
Auditory Hair Cell Regeneration And Gene Expression In Noise-Exposed Zebrafish (Danio Rerio), Julie Schuck
Auditory Hair Cell Regeneration And Gene Expression In Noise-Exposed Zebrafish (Danio Rerio), Julie Schuck
Masters Theses & Specialist Projects
Fishes are capable of regenerating sensory hair cells in the inner ear after exposure to excessive noise. However, a time course of auditory hair cell regeneration has not been characterized for zebrafish, nor has gene expression following noise exposure. To establish a time course of hair cell regeneration, adult zebrafish were exposed to a 100 Hz pure tone at 179 dB re 1 |u.Pa RMS for 36 hours, and then allowed to recover for 0 to 14 days before morphological analysis. Hair cell loss and recovery were determined using phalloidin and DAPI labeling to visualize hair cell bundles and nuclei, …
The Effects Of Human/Wildlife Conflict On The Potential For Community-Based Ecotourism In The Kasigau Region Of Southeast Kenya, Natalie Mountjoy
The Effects Of Human/Wildlife Conflict On The Potential For Community-Based Ecotourism In The Kasigau Region Of Southeast Kenya, Natalie Mountjoy
Masters Theses & Specialist Projects
Many believe community-based ecotourism (CBE) can assist in conservation efforts and community development; however, little research has been done to assess the potential of CBE in a specific region. As part of a large, long-term, international research project, I define three problematic areas that may impede successful CBE efforts in the Kasigau location of southeast Kenya: bushmeat utilization, community attitudes and wildlife abundance. Samples of meat purchased from butcheries and meat markets are identified to species using molecular analysis, community attitudes are ascertained via written social surveys and transect sampling methods are used to determine the relative abundance and diversity …
The Environmental Factors Regulating The Distribution Of Crayfish In The Upper Green River Basin Kentucky, Usa, Eva Ngulo
Masters Theses & Specialist Projects
Despite the importance of crayfish in aquatic systems there are major issues threatening their conservation, including invasive species, habitat alterations, and species with small distributions or have limited geographical ranges. There is limited information regarding native range, habitat requirements, life histories and biological interactions between crayfish species. In order to examine the relationship between lotic crayfish assemblages and environmental variables at both the watershed and reach scales, data were collected from 46 stream segments in the Upper Green River Basin of Kentucky, U.S.A. An independent sample t-test compared crayfish densities between segments with gravel - small cobble, and large cobble …
Some Barriers To Development In Cameroon, Kenya And Swaziland, Matthew Moore
Some Barriers To Development In Cameroon, Kenya And Swaziland, Matthew Moore
Masters Theses & Specialist Projects
In the study of development, researchers attempt to identify and measure the independent variables believed to influence economic growth and social development indicators in countries throughout the world. These researchers employ quantitative cross-national research methods, also known as the variable-oriented approach, while others may pursue a more case-oriented approach and examine a handful of countries employing a historical-comparative method. Education is a variable that has been identified in both of these research traditions to be positively related to the development of a country. However, when the effects of education on development are examined cross-nationally, it is clear that the countries …
The Whitehead Link On The Cubic Lattice, Elizabeth Haynes
The Whitehead Link On The Cubic Lattice, Elizabeth Haynes
Masters Theses & Specialist Projects
The cubic lattice is a graph in Â3 where the vertices are points with integer coordinates and edges are unit length line segments parallel to the x-, y-, or z-axis. A step is a line segment that connects one vertex to a neighboring vertex one unit away in the x-, y-, or z-direction. This thesis will show that the Whitehead Link needs at least 34 steps to be embedded on the cubic lattice.
P27 Expression In Endothelin-1 Stimulated Mitogenesis, Joseph Kiriu
P27 Expression In Endothelin-1 Stimulated Mitogenesis, Joseph Kiriu
Masters Theses & Specialist Projects
Bovine corneal endothelial cells (BCECs) have been shown in our lab to synthesize and secrete endothelin-1 (ET-1). The endothelin-1 binds ETA receptors, this elevates intracellular calcium, stimulate DNA replication and cell division. This investigation explores ET-l's role as a mitogenic factor in corneal endothelial cells and addresses whether mitogenic activity is mediated through the cyclin dependent kinase inhibitor p27. BCEC were isolated from bovine eyes and grown in DMEM-10% serum in a 5% C02, 37° C incubator. Confluent cultures of BCEC were incubated for 24 hours with lOOnM Endothelin-1, luM BQ123 and BQ123 +100nM Endothelin-1 and some left untreated. Total …
The Effect Of Ecological Gradients On The Fish Assemblages Of The Green And Tradewater River Basins Of Kentucky, Brian Lewis
The Effect Of Ecological Gradients On The Fish Assemblages Of The Green And Tradewater River Basins Of Kentucky, Brian Lewis
Masters Theses & Specialist Projects
The composition of lotic assemblages is influenced by many landscape factors. Foremost among these are basin geomorphology, fluvial and substrate characteristics, stream size, and land use. The primary purpose of this investigation was to determine if fish assemblages within Kentucky's Green River and Tradewater River Basins were associated with local scale environmental gradients and, if so, which gradients were the most important in shaping fish assemblages and which fish species were most closely associated with these gradients. A secondary purpose was to determine which regionalization or characterization strategy best segregated streams within the study area according to fish assemblages. Eighty-eight …
Conservation Studies Of Insect Cave Faunas In Mammoth Cave National Park And Ghana, West Africa, Chris Dewildt
Conservation Studies Of Insect Cave Faunas In Mammoth Cave National Park And Ghana, West Africa, Chris Dewildt
Masters Theses & Specialist Projects
As part of a long term ecological monitoring effort at Mammoth Cave National Park, a blind cave beetle, Neaphaenops tellkampfi, was collected and data on populations trends gathered from September 2005 through December 2006 in Great Onyx Cave. The sex and age of each individual in each of 15 sites were determined and density trends of the entire population was measured. The species was chosen due to its role as an indicator species, since potential anthropogenic threats to the environment can be detected via population response. This was the initial implementation of a new monitoring method and a test of …
Phylogenetic Analysis Of The Cetonini Of The New World (Coleoptera: Scarabaeidae: Cetoninae), Jesus Orozeo
Phylogenetic Analysis Of The Cetonini Of The New World (Coleoptera: Scarabaeidae: Cetoninae), Jesus Orozeo
Masters Theses & Specialist Projects
The American genera of Cetoniini (Coleoptera: Cetoniinae) are analyzed. Fifty-eight morphological characters of seventy two taxa, including Cetoniini from the entire world and other representative tribes of Cetoniinae, were included in a phylogenetic analysis and studied under the parsimony criterion. The Cetoniini, a tribe including species from all continents, is monophyletic and appears supported by two homoplastic characters: the elytra-thorax articulation in a glove-like shape and the mesosternal process basally compressed and apically expanded in shape. No clade supporting a hypothesis of common ancestry for the American species was found. Of the traditionally defined genera in the American continents only …
