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...

Diversity and Evolution of Sexual Traits in Ground Beetles (Family Carabidae)

Creator:: Gomez, R. Antonio
Abstract:: Biologists have long been fascinated with reproductive traits, in part because they are frequently exaggerated or showy, and they commonly vary among closely related species. Exaggerated sexual traits, in particular, have been the focus of intense empirical and theoretical research, but most of this work has focused on traits involved...

Multiple Stressors Drive Changes in Coral Microbiome Diversity and Composition Demonstrating the Role of a Bacterial Symbiont in Microbial Community Sensitivity and Resilience

Creator:: Maher, Rebecca L.
Abstract:: On coral reefs, disturbances rarely occur in isolation. Global stressors such as increasing seawater temperature often coincide with local stressors like nutrient pollution. In the face of increasing anthropogenic stress, corals can function as environmental sentinels, although little is known about how multiple stressors interact to disrupt their associated bacterial...

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....

The effects of environmental stressors on cardiac gene expression and contractility in rainbow trout (Oncorhynchus mykiss)

Creator:: Momoda, Tracey S.
Abstract:: Rainbow trout (Oncorhynchus mykiss) experience a variety of stressors in their natural environment as well as in aquaculture that can have negative effects on their physiology. The effects of physiological stress and endocrine disruption have been well described in fish. However, there is a scarcity of information on the effects...

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...

All hosts are not created equal : variation in amphibian responses to an emerging fungal pathogen and why it matters

Creator:: Gervasi, Stephanie S.
Abstract:: Emerging infectious diseases are increasing globally and are a threat to human, wildlife, and ecosystem health. The emerging fungal pathogen, Batrachochytrium dendrobatidis (Bd), or amphibian chytrid fungus, is associated with worldwide amphibian population declines and extinctions. Bd has been found on every continent where amphibians exist and has been documented...

The heat shock response and its regulation in congeneric marine snails (genus Tegula) from different thermal habitats : implications for the limits of thermotolerance and biogeographic patterning

Creator:: Tomanek, Lars
Resource Type:: Dissertation

Linking marine communities and ecosystems : invertebrates mediate nutrient availability in intertidal communities

Creator:: Bracken, Matthew E.
Abstract:: While community ecologists have traditionally focused on local-scale processes, it has become apparent that a broader perspective, which explores the community-level ramifications of material fluxes within and between ecosystems, is necessary to effectively evaluate bottom-up influences on community structure and dynamics. In this dissertation, I employed ecosystem principles to understand...

Regulation by male-specific fruitless of neural circuitry used during courtship and copulation behavior in Drosophila melanogaster

Creator:: Latham, Kristin Lynn
Abstract:: Courtship and copulation behaviors in Drosophila melanogaster males are regulated by sex-specific products from the gene fruitless (fru). Male-specific FRU proteins (FRU[superscript M]) are putative transcription factors of the BTB-ZnF family that likely act by controlling development and maintenance of the neural circuitry used during male sexual behavior. However, which...
