Modifications to Rearing Environments as a Method for Reducing Domestication Selection in Hatchery-reared Steelhead (Oncorhynchus mykiss)

Creator:: Obley, Miriam
Abstract:: Since the decline of salmonid populations in the Pacific Northwest, supplementation programs have become frequently implemented by hatcheries as a way to protect and conserve wild stock. However, hatchery-reared fish have lower fitness than wild fish which is likely due to adaptation to the hatchery environment, i.e., domestication selection. Fish...

Cellular Recognition, Division, and Proliferation in the Cnidarian-Dinoflagellate Symbiosis

Creator:: Tivey, Trevor R.
Abstract:: Cnidarians and their symbiotic dinoflagellates form a productive mutualism that shapes marine environments. In this symbiosis, dinoflagellate species from the family Symbiodiniacea reside within cnidarian host gastrodermal cells and provide the host with photosynthetically fixed carbon in exchange for host metabolites. This nutritional exchange allows both partners to thrive in...

From Microbes to Megafauna: The Ecology of Gut Microbiomes in Wild Herbivores

Creator:: Couch, Claire E.
Abstract:: All mammals host communities of commensal microbes in and on their bodies. Recent technological advances, combined with experimental studies in laboratory animals, are beginning to reveal the ubiquitous links between the gut microbiome and host disease, metabolism, immunity, and numerous other host functions. A new challenge of microbiome research is...

Phylogenomics and Evolution of Ground Beetles, with an Emphasis on the Speciose Tribes Chlaeniini and Bembidiini (Coleoptera: Carabidae)

Creator:: Pflug, James M.
Abstract:: In this dissertation, I investigate the evolution and genomes of carabid beetles, a worldwide family of over 38,000 species. I focus on two species-rich groups, the tribes Chlaeniini and Bembidiini, both of which are primarily found on the shores of bodies of water. The former are distinctive for their defensive...

Gene expression of four carbonic anhydrase paralogs across the symbiotic states of the model temperate sea anemone, Anthopleura elegantissima (Brandt 1835)

Creator:: Meier, Emily K.
Abstract:: Anthropogenic CO₂ emissions are shifting the global climate equilibrium, causing widespread losses in biodiversity. Anthozoan cnidarians are some of the species most vulnerable to environmental change. Environmental stress causes corals and sea anemones to expel their endosymbiotic algae, which constitute a primary source of nutrition for some Anthozoa. Carbonic anhydrase...

Influence of the Environment and Morphology on Physiological and Genomic Homeostasis in a Temperate Cnidarian-microbe Symbiosis

Creator:: Koch, Jack C.
Abstract:: Climate change and other anthropogenic impacts are threatening the existence of millions of species around the globe. On western continental boundaries, the large-scale secondary process of upwelling, which brings low pH, deoxygenated, high nutrient seawater to the surface, is compounded by climate change, that together could drive some species to...

Context and Scale Mediate the Impact of Climate on a Widespread Avian Predator

Creator:: Brawner, Michael D.
Abstract:: Anthropogenic climate change is threatening biodiversity as I currently understand it. There is now a large body of work highlighting species responses, globally, to this threat. Importantly, responses at the species level emerge from responses at lower levels of biological organization (individuals and populations) across a species’ geographic range. For...

Abstract:: The intricate relationship between wildlife health and the quality of their environment is well established, with technological advances increasing our understanding and aiding the unraveling of underlying mechanisms. Large herbivores require forage of sufficient quality to maintain their condition to reproduce and survive, all while warding off parasites and predators...

Creator:: Sproul, John S.
Abstract:: Species are one of the foundational units upon which entire fields of scientific inquiry are built. Discovering and documenting the planet’s biodiversity remains one of the grand challenges of science. A proper conceptualization of species provides a critical framework for diverse fields such as biophysics, biochemistry, agriculture and pharmacology, and...
