Metabolic adjustment to temperature in Strongylocentrotus purpuratus (Stimpson)

Creator:: Ulbricht, Richard Jules
Abstract:: The metabolism of Strongylocentrotus purpuratus (Stimpson) was investigated at several levels of urchin organization. Some experiments were performed with tissues from recently collected (acclimatized) urchins, Other experiments were performed with tissues from urchins held at one of two temperatures (acclimated) for 30 days. Body-component oxygen consumption was measured for bodywall,...

Neuroendocrine mechanisms that regulate context-dependent behavioral responses to acute stress

Creator:: Coddington, Emma
Abstract:: In nature, animals survive threats by responding physiologically and behaviorally in ways that are appropriate to the situation. Which responses are appropriate depend on the animals' surroundings and current physiological and behavioral state. This dissertation investigated the neuroendocrine mechanisms that control context-dependent behavioral responses to stress by focusing on the...

The incidence and development of somatic polyploidy in the marine isopod Idothea wosnesenskii

Creator:: Matlock, Daniel Budd
Abstract:: (Brandt) were surveyed for the presence of polyploid cells. Large polyploid cells were found in the hepatic cecum, gut and sheath of the testis. The relative DNA content of the polyploid nuclei was measured by means of two wavelength cytophotometry. Histograms plotted from the data provide information on the level...

Pheromonal mediation of reproductive behavior in the brown tree snake

Creator:: Greene, Michael John
Abstract:: In animals, reproductive behaviors serve to attract individuals together during the breeding season and to coordinate the behavioral and physiological states of individuals so that mating can successfully occur. In snakes, the various reproductive behaviors including courtship, mating, courtship inhibition, male combat and trailing are mediated primarily by pheromones. Pheromones...

Molecular investigation of the cnidarian-dinoflagellate symbiosis and the identification of genes differentially expressed during bleaching in the coral Montipora capitata

Creator:: Hauck, Laura L.
Abstract:: Cnidarians, such as anemones and corals, engage in an intracellular symbiosis with photosynthetic dinoflagellates. Corals form both the trophic and structural foundation of reef ecosystems. Despite their environmental importance, little is known about the molecular basis of this symbiosis. In this dissertation we explored the cnidariandinoflagellate symbiosis from two perspectives:...

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...

Comparative studies of the population ecology and life history patterns of an alkaline salt lake insect : Ephydra (Hydropyrus) hians Say (Diptera:Ephydridae)

Creator:: Herbst, David B.
Abstract:: Seasonal abundance and life history traits were compared between populations of the brine fly Ephydra (Hydrokyrus) hians Say (Diptera:Ephydridae), from two western Great Basin alkaline salt lakes. Abert Lake, Oregon, has a relatively low salinity (20-30 g/1 total dissolved solids) and more co-inhabitant benthic species than the higher salinity Mono...

Modulation of respiratory burst activity of trout (Oncorhynchus mykiss) phagocytic cells

Creator:: Galvan, Irja S.
Abstract:: In a comparison of the mammalian and fish immune systems many similarities and differences are found. While most of the differences occur in the acquired or lymphoid arm of immunity, the nonlymphoid immune systems of fish and mammals share many similarities. For instance, both animal groups use phagocytic neutrophils and...
