A Quantitative Analysis Of Morphological Changes In Specific Laminae Of The Olfactory Bulb Of Adult Zebrafish Following Peripheral Sensory Deafferentation, Travis L. Devlin Dec 2006

A Quantitative Analysis Of Morphological Changes In Specific Laminae Of The Olfactory Bulb Of Adult Zebrafish Following Peripheral Sensory Deafferentation, Travis L. Devlin

Masters Theses

Permanent removal of the olfactory organ in adult zebrafish has been shown to result in a significant reduction in the total volume of the ipsilateral olfactory bulb. The overall objective of the current project was to investigate the hypothesis that contact between the axons of the olfactory sensory neurons and the olfactory bulb is necessary for the maintenance of the normal post-synaptic organization of the olfactory bulb by quantifying the morphological changes that take place within specific laminae of the olfactory bulb following peripheral deafferentation. Complete, unilateral ablation of the olfactory organ resulted in permanent deafferentation of the ipsilateral olfactory …


Metabolic And Phenotypic Characterization Of Aerobic Pcb Degrading Bacteria Isolated From Kalamazoo River Sediments, Brenton K. Lehmkuhl Dec 2006

Metabolic And Phenotypic Characterization Of Aerobic Pcb Degrading Bacteria Isolated From Kalamazoo River Sediments, Brenton K. Lehmkuhl

Masters Theses

The Kalamazoo River is contaminated with polychlorinated biphenyls (PCBs) which are neurotoxins and suspected carcinogens. The goal of this study was to isolate, identify, and metabolically characterize PCB degrading strains of aerobic bacteria. Biphenyl enrichments resulted in the isolation of putative PCB degrading strains from different locations along the river. Based on 16S rRNA gene analysis the isolated strains were identified as belonging to the genera of Achromobacter, Acidovorax, Cellulosimicrobium, Paenibacillus, Pseudomonas, and Rhodococcus. These strains were screened for their PCB degrading ability and congener specificity. All of the isolated strains degraded PCBs via the 2,3-dioxygenase pathway. The range …


Changes In Microbial Community Structure Of Petroleum Contaminated Sediments Are Reflected In Subsurface Geophysical Signatures, Jonathan P. Allen Aug 2006

Changes In Microbial Community Structure Of Petroleum Contaminated Sediments Are Reflected In Subsurface Geophysical Signatures, Jonathan P. Allen

Masters Theses

Petroleum contamination of sediments leads to dynamic changes in the subsurface. These include changes in the microbiota as well as in the subsurface geophysical and geochemical properties. Anomalously high conductivity values observed in subsurface zones contaminated with light non aqueous phase liquids (LNAPLs) have been suggested to be the result of microbial activity. Therefore, we investigated the interdependence between geoelectrical signatures and microbial community structure in petroleum contaminated field sediments and laboratory column experiments. Spatial and temporal changes in electrical conductivity of the subsurface paralleled changes in microbial community composition, with the highest conductivity values concomitant with specific anaerobic hydrocarbon-degrading …


Identification And Characterization Of Cellular Targets Of The Bacterial Cytotoxin Yopt In Saccharomyces Cerevisiae, Paul David Caccamo Aug 2006

Identification And Characterization Of Cellular Targets Of The Bacterial Cytotoxin Yopt In Saccharomyces Cerevisiae, Paul David Caccamo

Masters Theses

Human pathogenic Yersinia spp. utilize Type III Secretion to deliver six effector proteins into host cells. The injected proteins resemble eukaryotic signal transduction molecules and are capable of disrupting signaling pathways in order to subvert the functions of the targeted cell or disrupt communication with surrounding cells. As a result, bacterial invaders are not only able to survive the threat of a host immune response, but can thrive despite it. YopT is a cysteine protease that cleaves RhoGTPases, releasing them from the membrane and thus from their role as initiators of signaling pathways, including the nucleation of actin and …


Predicting Distribution, Habitat Suitability And The Potential Loss Of Habitat For Sitta Formosa, The Beautiful Nuthatch, Jill C. Witt Apr 2006

Predicting Distribution, Habitat Suitability And The Potential Loss Of Habitat For Sitta Formosa, The Beautiful Nuthatch, Jill C. Witt

Masters Theses

The beautiful nuthatch, Sitta formosa, occurs in high-altitude evergreen and semi-evergreen forests throughout the south and southeastern extent of the Himalayan Mountains. Populations of S. formosa are small, declining and severely fragmented as a result of habitat degradation and fragmentation, and therefore it is considered vulnerable by the World Conservation Union and is included in the 2004 Red List of Threatened Species. I used ecological niche factor analysis to model the potential distribution and predict suitable habitat for S. formosa. By using 59 presence locations, collected from museum specimens and biodiversity surveys, and together with topographic and …

Changes In The Diet Of Lake Trout (Salvelinus Namaycush) In Near-Shore Lake Michigan With The Invasion Of The Round Goby (Neogobius Melanostomus): 1995-2005, Marybeth Kathryn Brey Jan 2006

Changes In The Diet Of Lake Trout (Salvelinus Namaycush) In Near-Shore Lake Michigan With The Invasion Of The Round Goby (Neogobius Melanostomus): 1995-2005, Marybeth Kathryn Brey

Masters Theses

The predator-prey base of the Great Lakes has been altered since the early 1900's, with the majority of these changes occurring due to invasive species such as the sea lamprey (Petromyzon marinus), alewife (Alosa pseudoharangus), and rainbow smelt (Osmerus mordax). These changes have forced large piscivorous fish to find alternate prey species. One predator, the lake trout (Salvelinus namaychush) has experienced a series of diet shifts in the last century, due to a changing prey base. In recent years the Great Lakes, particularly Lake Michigan has experience a new invader, the round goby (Neogobius melanostomus), which has colonized the …
