Identification and characterization of vasotocin and mesotocin peptides and receptors

Creator:: Searcy, Brian T.
Abstract:: The neurohypophysial peptide system is involved in modulating a variety of physiological, neurological, and behavioral responses in vertebrates. The principal forms of these peptides in non-mammalian tetrapods are vasotocin (VT) and mesotocin (MT). The studies described in this thesis used pharmacological, molecular, and biochemical techniques, along with phylogenetic analyses, to...

Aggregational behavior in the boreal toad Bufo boreas boreas Baird and Girard

Creator:: Dorsch, Anthony James
Abstract:: The object of this study was to investigate the possibilities of tracing aggregational behavior among Bufo boreas boreas larvae with reference to tadpole development, and to attempt to determine what aggregational factors initiate and maintain this behavior. Additionally, an attempt was made to determine the significance of temperature as an...

Stress and reproduction in male garter snakes

Creator:: Moore, Ignacio T.
Abstract:: Animals respond to stressful situations with increases in plasma levels of glucocorticoid stress hormones. These hormones originate from the adrenal cortex in response to stimulation of the hypothalamic-pituitary-adrenal axis. Glucocorticoids (corticosterone in reptiles) function to mobilize energy and suppress unnecessary functions until the stress passes. Among these immediately unnecessary functions...

Phytoplankton shading of marine benthic macrophytes: Implications for intertidal community structure

Creator:: Kavanaugh, Maria T.
Abstract:: Previous observations of light levels and phytoplankton abundances along the Oregon coast demonstrated that phytoplankton attenuated light sufficiently to potentially limit the growth of intertidal macrophytes and therefore structure local intertidal communities. Inspired by this observation, in spring 2004, I initiated a study to quantify the direct and indirect benthic...

An experimental test of optimal outbreeding in the harpacticoid copepod Tigriopus californicus (Baker)

Creator:: Brown, Alice F.
Abstract:: Hypotheses concerning relative costs of inbreeding and outbreeding were evaluated for the harpacticoid copepod Tigriopus californicus, which inhabits high intertidal tidepools. Field studies indicate high variation in biotic and abiotic parameters among pools. These findings coupled with previous information about very low dispersal rates and local adaptations to individual pools...

Marine herbivore-plant interactions : the feeding ecology of the sea slug Placida dendritica

Creator:: Trowbridge, Cynthia D.
Abstract:: The feeding ecology of a common temperate mesoherbivore, the oligophagous sea slug Placida dendritica (Gastropoda: Opisthobranchia: Ascoglossa), was examined from April 1985 to June 1989. Along the central coast of Oregon, Placida consumed three host species: the low intertidal green algae Codium setchellii, C. fragile, and Bryopsis corticulans. Individual slugs...

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...

Population genetics of ranid frogs : investigating effective population size and gene flow

Creator:: Phillipsen, Ivan C.
Abstract:: This dissertation focuses on the evolutionary forces of genetic drift and gene flow in frog populations. The balance of these two forces and the force of mutation largely determine the amount of neutral genetic variation within populations as well as the degree of genetic similarity among populations. The stochastic evolutionary...

Singing behavior of the Bewick's wren : development, dialects, population structure, and geographical variation

Creator:: Kroodsma, Donald E.
Abstract:: The songs of the Bewick's Wren are discrete units of one to three seconds duration with intersong intervals several times the length of the song. Individual song repertoires at the William Finley National Wildlife Refuge, Oregon, range from 13 to 20 song types, and a given song type is repeated...

Reproductive and aggressive behaviors in the giant hairy desert scorpion

Creator:: Tallarovic, Sara K.
Abstract:: The giant hairy desert scorpion, Hadrurus arizonensis, is a long-lived species of North American scorpion that is presented here as an important model for research in mating systems evolution and sexual selection. Many behaviors found in this species were undocumented and are described here for the first time. This thesis...

The roles of nutrient dynamics, oceanography, and light in the structure and functioning of rocky intertidal macrophyte assemblages

Creator:: Close, Sarah L.
Abstract:: The influence of the physical environment on organisms has long been a subject of ecological research. But, the complex drivers of environmental variation, and the multiple scales at which this can occur, make studying this topic a difficult challenge. In rocky intertidal habitats, oceanographic- and climate-scale variability influence benthic communities...

The effects of an emerging pathogen on amphibian host behaviors and interactions

Creator:: Han, Barbara A.
Abstract:: Contemporary environmental change encompasses massive biodiversity loss and increasing numbers of emerging diseases worldwide. As part of a global biodiversity crisis, amphibians are disappearing at unprecedented rates. Batrachochytrium dendrobatidis is an emerging infectious pathogen prominently associated with many declines. Chapter 1 reviews the past decade of research on this system...

Nearshore distribution of barnacle and mussel larvae and oceanographic mechanisms of onshore transport and delivery

Creator:: Tyburczy, Joe A.
Abstract:: Recruitment of larvae from the plankton is an important determinant of community structure in marine systems. In populations of many marine species, recruitment determines the basic demographic parameters of immigration, emigration, and reproduction. Moreover, the effect of recruitment as an "ecological subsidy" can determine the strength of interactions among species...

Abstract:: A method for isolating the salt gland (SG) from the larval brine shrimp has been developed. This extra-renal organ is removed from 5-10% of Stage Inauplii by vortexing after incubating the animals at 37°C for 8 hours in a saline solution buffered with 100 mM sodium phosphate at pH 7.6....
