Fish Assemblages In Manistee River Tributaries: Longitudinal Distribution Analysis, Seasonal Variation, And Riparian Improvement Evaluation, Nicholas J. Gressick
Fish Assemblages In Manistee River Tributaries: Longitudinal Distribution Analysis, Seasonal Variation, And Riparian Improvement Evaluation, Nicholas J. Gressick
Masters Theses
Sedimentation affects both stream physical and biological integrity. Improperly designed stream passage accompanied with sedimentation and altered hydrology can impede fish passage and reduce fish assemblage integrity. The purpose of this study was to: 1) quantify impacts of poorly constructed road stream crossings and eroding banks on fish assemblages, and 2) assess these sites as sediment sources and connectivity breaks on entire fish assemblages and individual fish species. Electrofishing was conducted during spring and fall 2004 and 2005. A total of 29 electrofishing reaches were sampled which included 5 road-stream and streambank restoration sites. Sickle Creek (1st order) had reduced …
A Community Ecology And Stable Isotope Study Of Plankton, Macroinvertebrate, And Fish Communities Surrounding Groundwater Vents In Lake Huron, Michigan, Thomas Garrison Sanders Jr.
A Community Ecology And Stable Isotope Study Of Plankton, Macroinvertebrate, And Fish Communities Surrounding Groundwater Vents In Lake Huron, Michigan, Thomas Garrison Sanders Jr.

Extreme environments can create ecotones with uncharacteristic physicochemical conditions and ecological communities. Recently, several submerged sinkholes were discovered in Lake Huron where hypoxic groundwater that is rich with dissolved ions intrudes into surrounding lake water. Researchers have documented large growths of cyanobacteria and chemosynthetic bacteria surrounding these groundwater vents, but little is known if this production is utilized by upper trophic level organisms and how the environmental conditions affect local community density and diversity. My objectives were threefold: (1) I wanted to confirm the presence and describe the nature and extent of chemical and physical gradients in the sublacustrine sinkhole …
From In-Vitro To In-Vivo: Corporate Development And Efficacy Of A Topical Hair Growth Agent Derived From Natural Extracts, Kelly Michael Glynn
From In-Vitro To In-Vivo: Corporate Development And Efficacy Of A Topical Hair Growth Agent Derived From Natural Extracts, Kelly Michael Glynn
Masters Theses
Androgenetic alopecia (male pattern baldness) affects up to 50% of the world’s population, propelling the development for a possible treatment. The hair follicle is influenced by several genetic and physiologic factors, which, when gone awry, lead to androgenetic alopecia. Vascular endothelial and keratinocyte growth factors are believed to be promoters of hair growth, as is inhibition of the proteasome complex. The cytokine IL-1α is also known to regulate follicle dynamics. The research objective described herein was an attempt to develop a botanical blend, which could mediate the above biomarkers, be successfully incorporated into a safe topical product and be evaluated …
Sediment Remediation Impacts On Macroinvertebrate Community Structure: Assessing The Success Of Urban Stream Restoration, Laurie Beth Nederveld
Sediment Remediation Impacts On Macroinvertebrate Community Structure: Assessing The Success Of Urban Stream Restoration, Laurie Beth Nederveld
Masters Theses
Land use practices altering the natural landscape have resulted in the widespread degradation of stream ecosystems and the need for urban stream restorations. While a number of studies have evaluated the success of these stream restoration efforts, few have assessed the recovery of macroinvertebrate communities following the remediation of contaminated sediments. The purpose of my study was to evaluate the impact of sediment remediation activities on macroinvertebate abundance, diversity, and richness to determine the success of stream restoration in Ruddiman Creek, a small stream in the Muskegon Lake watershed. During my investigation, macroinvertebrate samples were collected from all available habitat …
