Sperm depletion and sperm competition in the red-sided garter snake, Thamnophis sirtalis parietalis

Creator:: Kerns, Amelia R.
Abstract:: Sperm competition is the post-copulatory analog of male-male combat, wherein sperm from more than one male coincide in a female’s reproductive tract and compete with one another for fertilization of a limited number of ova. Post-copulatory sexual selection, such as sperm competition, can be a powerful driving force for the...

Neural gene expression profiling in chinook salmon (Oncorhynchus tshawytscha) of alternate run times

Creator:: Bernier, Jeremiah C.
Abstract:: Chinook salmon (Oncorhynchus tshawytscha) display the greatest variability of return times to freshwater of all Pacific salmon. Differential return times to freshwater have segregated populations of Chinook into two broad types or runs, fall and spring, named for the time of year in which they migrate to freshwater. Migration time...

Detection of Physical and Biological Fronts in the Northern California Current System and the Drivers Behind Their Seasonal to Interannual Variability

Creator:: Jamil, Aliya L.
Abstract:: Oceanic fronts mark the boundary between two water masses and are often sites of complex bio-physical processes and multi-trophic level interactions, making them particularly important features in marine ecosystems. As global climate change induces multi-scale shifts in the driving physical mechanisms of fronts, spatiotemporal tracking of frontal variability can aid...

Identification of candidate genes for survival and their use in predicting field performance of Pacific oyster Crassostrea gigas families in coastal waters

Creator:: Lang, Robert Paul
Abstract:: Summer mortality of farmed Pacific oysters causes financial losses for shellfish growers, and selective breeding to improve survival of offspring is a promising way to reduce losses. This dissertation has two objectives to assist the development of tools for use in selective breeding programs. Objective 1: Identify candidate genes for...

Ultraviolet radiation as an environmental stressor of amphibians

Creator:: Bancroft, Betsy A.
Abstract:: My thesis explored the effects of and potential mediating mechanisms for an important environmental stressor, ultraviolet-B (UVB) radiation. UVB radiation has negative effects on organisms in both terrestrial and aquatic systems. I used meta-analysis to quantify the effects of UVB radiation on a diversity of aquatic organisms (Chapter 2). UVB...

Advancing marine reserve science : from field experiments to marine conservation planning tools

Creator:: Leslie, Heather M.
Abstract:: This dissertation focuses on science relevant to the design and implementation of marine reserves. The chapters explore a range of topics related to among-site variation in population, community, and ecosystem dynamics. My results demonstrate the value and feasibility of integrating this knowledge into more comprehensive conservation and management approaches. While...

Establishment of an in vitro System for Studying Mycobacterium avium Protein Secretion

Creator:: Chinison, Jessica J.
Abstract:: Cases of pulmonary diseases caused by Mycobacterium avium complex (MAC) have increased over the years and have become a major health concern in Europe, Asia, and the United States. MAC, comprised of M. avium species and M. intracellulare, are found everywhere in the environment: in water sources and the soil....

Linkages between mangrove forests and coral reefs : quantifying disturbance effects and energy flow between systems

Creator:: Granek, Elise F.
Abstract:: Interface habitats are considered valuable natural systems, tightly linked to adjacent habitats through the flow of matter and energy. However, there is limited research on mechanisms of connectivity such as movement of organisms and particulate matter and ways in which anthropogenic disturbance to interface habitats may affect immediate and adjacent...

Activation, modification and suppression of sex pheromone production in garter snakes

Creator:: Parker, M. Rockwell
Abstract:: Vertebrates communicate with one another and coordinate intraspecific reproduction by using a variety of sexually dimorphic signals, such as plumage, ornaments, sounds, and/or scents. These sexual dimorphisms are maintained by physiological factors, typically sex-specific hormones (though see Chapter 3 for an exception). The purpose of the research in this dissertation...

What is killing the corals? Viral and bacterial interrogations using metagenomics and microscopy

Creator:: Soffer, Nitzan
Abstract:: Corals have multiple roles in maintaining ocean health and are some of the world’s most diverse ecosystems. The coral animal is host to a multitude of taxa, including symbiotic dinoflagellate algae, fungi, bacteria, protists, and viruses. Environmental stressors and disease agents can perturb the delicate balance of the coral host...
