Transcriptome Analysis For Novel Peptide In Breeding Gland Of Hymenochirus Boettgeri, Minjin Ko

University of the Pacific Theses and Dissertations

The primary goal of the project was to find nucleotide sequences potentially encoding a pheromone from the breeding gland of Hymenochirus boettgeri. The reasons in searching for the sequence of a pheromone were to better understand the organism and to use the information for application in reproduction of other species. Due to climate change and rampant deforestation, such as in Africa’s Congo Basin, many amphibian species are being threatened. With these increasing threats, a viable option for the future may be breeding in captivity for the amphibian species. Pheromone characterization from the breeding gland of Hymenochirus boettgeri may help with …

Development Of A Biomarker Panel For Identifying Stressed Marine Mammals, Laura Pujade

University of the Pacific Theses and Dissertations

Increasing anthropogenic disturbance in marine ecosystems such as fishing, oil-drilling, and noise pollution can have detrimental effects on the reproduction and survival of apex predators such as marine mammals. Stress activates the hypothalamic-pituitary-adrenal (HPA) axis, resulting in increased circulating glucocorticoid (GCs) hormones, which alter expression of target genes encoding metabolic enzymes and other mediators of stress. Prolonged HPA axis stimulation may increase catabolism of nutrient stores and suppress immune and reproductive functions, impacting the fitness of marine mammals. GCs measurements are used to identify wild animals experiencing stress. However, these measurements may not be sensitive enough to distinguish between an …

Phylogenomic Analyses Clarify Butterfly Species Within The Genus Speyeria Despite Evidence Of A Recent Adaptive Radiation, Erin Thompson

University of the Pacific Theses and Dissertations

The North American genus Speyeria is an especially challenging radiation of butterflies due to ongoing hybridization, incomplete lineage sorting, and similar morphological characters among species. Adaptive radiations often require considerable evidence in order to resolve the evolutionary relationships of closely related individuals. Previous studies of this genus have found paraphyly among species and have been unable to disentangle these taxa due to a lack of data and/or incomplete sampling of the genus. As a result, the interspecific relationships among Speyeria remain unresolved. In an attempt to achieve phylogenetic resolution of the genus, we conducted population genomic and phylogenomic analyses of …

Characterization Of The Blood-Feeding Patterns Of Culex Quinquefasciatus In San Bernadino County, California, Aelish Ann Guinn

University of the Pacific Theses and Dissertations

Culex quinquefasciatus has been identified as one of the most prominent vectors of West Nile virus (WNV) in Southern California. WNV is a zoonotic disease that is endemic in North America and is known to primarily cause flu-like symptoms in humans, and in rare cases, life-threatening conditions. The goal of this study was to identify which animal species are most frequently fed upon by these mosquitoes in this region. To examine the relationship between blood-feeding patterns and West Nile virus activity in San Bernardino County, the feeding patterns of Cx. quinquefasciatus are determined in a variety of habitat types, which …

A Trio Of Sigma Factors Control Hormogonium Development In Nostoc Punctiforme, Alfonso Gonzalez Jr.

University of the Pacific Theses and Dissertations

Cyanobacteria are prokaryotes capable of oxygenic photosynthesis, and for many species, nitrogen fixation, giving cyanobacteria an important role in global carbon and nitrogen cycles. Furthermore, multicellular filamentous cyanobacteria are developmentally complex, capable of differentiation into different cell types, including cells capable of nitrogen fixation and cells for motility, making them an ideal platform for studying development, as well as for practical use in biotechnology. Understanding how developmental programmes are activated require an understanding of the role of alternative sigma factors, which are required for transcriptional activation in bacteria. In order to investigate the gene regulatory network and to determine the …

Foreman, J. N. Baker, J. A. Walker, J. D. Orkin, A. D. Melin, Kimberley A. Phillips, M. K. Konkel, M. A. Batzer

Psychology Faculty Research

Platy-1 elements are Platyrrhine-specific, short interspersed elements (SINEs) originally discovered in the Callithrix jacchus (common marmoset) genome. To date, only the marmoset genome has been analyzed for Platy-1 repeat content. Here, we report full-length Platy-1 insertions in other New World monkey (NWM) genomes (Saimiri boliviensis, squirrel monkey; Cebus imitator, capuchin monkey; and Aotus nancymaae, owl monkey) and analyze the amplification dynamics of lineage-specific Platy-1 insertions. A relatively small number of full-length and lineage-specific Platy-1 elements were found in the squirrel, capuchin, and owl monkey genomes compared to the marmoset genome. In addition, only a few older …

Animal and Food Sciences Faculty Publications

Bovine mammary gland biopsies allow researchers to collect tissue samples to study cell biology including gene expression, histological analysis, signaling pathways, and protein translation. This article describes two techniques for biopsy of the bovine mammary gland (MG). Three healthy Holstein dairy cows were the subjects. Before biopsies, cows were milked and subsequently restrained in a cattle chute. An analgesic (flunixin meglumine, 1.1 to 2.2 mg/kg of body weight) was administered via jugular intravenous [IV] injection 15-20 min prior to biopsy. For standing sedation, xylazine hydrochloride (0.01-0.05 mg/kg of body weight) was injected via the coccygeal vessels 5-10 min before the …

Externality In Hegel's Philosophy Of Nature, Martin Krahn

Electronic Theses and Dissertations

The topic of my dissertation is the metaphysics of laws of nature in Hegel’s philosophy of nature. I argue that Hegel differentiates laws of nature from norms of culture through a concept of “externality,” according to which the universals or laws of nature stand outside of, apart from, independent from their particulars. He contrasts this with norms of culture, where the universals are internal to the particulars, such that in culture the particular events or actions shape the norms, whereas in nature, the laws remain the same through their independence from the particular events. I then address the consequences this …

Using Clay Models To Measure Seasonal Predation On Eastern Red-Backed Salamanders, Emma Perry

Honors Program Theses and Projects

One of the many gaps we have in our knowledge of salamanders is that of predation. Most studies suggest that salamanders are eaten mainly by birds and snakes, but there are still several unanswered questions: What other types of animals tend to prey on salamanders? Is there any difference in predator type during different times of the year? In order to answer these questions, I studied predation on one particular species of salamander, Plethodon cinereus (eastern red-backed salamander). Models of the two primary color morphs of P. cinereus (striped and unstriped) were created using impressionable clay to determine types and …

Sex Determination By Morphological Measurements Of Young Rockhopper Penguins (Eudyptes Chrysocome) During The Crèche Phase, Virginia Morandini, Miguel Ferrer, Lynelle Perry, Marc Bechard

Raptor Research Center Publications and Presentations

To provide an easy and reliable work tool to identify the sex of Rockhopper Penguin (Eudyptes chrysocome) chicks, we weighed and measured 95 nestlings in the crèche phase during 24-31 January 2017 on the Falkland Islands, Argentina. Sex was subsequently determined using DNA analyses of blood from the same individuals. Significant differences were found in bill length (exposed culmen), bill depth and width, flipper length, and diagonal tarsus, but stepwise discriminant analysis showed bill length to be the best predictor for sex determination. Our model correctly classified 82.7% of males and 90.2% of females (overall correct classification 86.2%). …

Midguts, Microbes, And Mosquitoes: An Analysis Of The Microbiomes Of Aedes Aegypti And Aedes Albopictus, Flor Alicia Martinez

Theses and Dissertations

Experiment 1: Mosquito microbiomes are influenced by the environment and diets of mosquitoes. There is great variability within and among mosquito populations with few microbe inhabitants being well established among mosquitoes of similar species and environments. By understanding the potential variation in midgut microbiomes in lab and wild populations, we may assess the effect that microbiomes have on vector competency.

Experiment 2: Mosquito midgut microbes are essential for development and may influence the vector competency. Native and non-native strains of the midgut inhabitant, Cedecea, were introduced to laboratory colonies of Aedes aegypti and Aedes albopictus mosquitoes to help elucidate …

Illuminating Endocrine Evolution: The Power And Potential Of Large-Scale Comparative Analyses, Maren N. Vitousek, Michele A. Johnson, Jerry F. Husak

Biology Faculty Research

Hormones are central mediators of genotype–phenotype and organism–environment interactions. Despite these important functions, the role of selection in shaping hormonal mediators of phenotype remains poorly understood. Thanks to decades of work by endocrinologists, circulating hormone levels have been measured in a diversity of organisms. Variation in other endocrine traits and mediators (e.g., receptor expression and binding globulins), and the hormonal response to standardized challenges (e.g., restraint, pharmacological challenges) are also increasingly measured in both captive and free-living populations. Large-scale comparative analyses of the multitude of available endocrine data represent a particularly promising approach to addressing the function and evolution of …
