Bridging environmental physiology and community ecology : temperature effects at the community level

Creator:: Iles, Alison C.
Abstract:: Most climate change predictions focus on the response of individual species to changing local conditions and ignore species interactions, largely due to the lack of a sound theoretical foundation for how interactions are expected to change with climate and how to incorporate them into climate change models. Much of the...

The ecology of ocean acidification : integrating the effects of pH variation among other environmental stressors on biogeography and organismal performance in rocky intertidal communities

Creator:: Rose, Jeremy M.
Abstract:: Ocean Acidification (OA) has emerged as a major threat to marine ecosystems, particularly regarding calcifying organisms. A growing body of literature describing laboratory investigations into pH stress indicates broadly deleterious effects for calcifiers, but responses vary greatly across taxa and can be influenced by variations in other environmental characteristics. Scaling...

The effects of multiple pathogens on amphibians in the Pacific Northwest

Creator:: Romansic, John M.
Abstract:: The earth is undergoing a “biodiversity crisis” characterized by loss of populations, species, genetic diversity, and ecosystem services. Part of this crisis consists of population declines, extinctions, and increased incidence of deformities in amphibians. It is unknown whether deformities contribute to these declines. Many cases of population declines in amphibians...

Heart rate, survivorship, oxygen consumption, and metabolic end product accumulations in the intertidal limpets Collisella pelta and Collisella digitalis in relation to desiccation and hypoxia

Creator:: Boese, Bruce Leon
Abstract:: The heart rate, oxygen consumption, survivorship, and 1-lactate accumulation were determined in the intertidal limpets Collisella pelta and Collisella digitalis in relation to laboratory desiccation at 15°C or 30°C. Water loss was computed as a percentage of total initial body water (wet weight - dry weight). Although water was lost...

An ultrastructural study of early cleavage in Mytilus

Creator:: Elvin, Patricia J.
Abstract:: Ultrastructural analysis and chemical inhibition studies were carried out on first cleavage of Mytilus zygotes to determine possible relationships between the mitotic apparatus and the cortex during polar lobe formation. The stages of mitosis correlated with the appearance of the polar lobe were first determined by light microscopy. The polar...

A biological and taxonomic study of selected myxosporida of some Oregon fresh-water fishes

Creator:: Wyatt, Ellis Junior
Abstract:: Biological studies were conducted on a histozoic myxosporidan Myxobolus insidiosus (Wyatt and Pratt, 1963) from the musculature of Oncorhynchus tshawytscha (Walbaum). This organism is known to occur in spring chinook salmon in Oregon and coho salmon O. kisutch (Walbaum) in Washington. In addition Myxobolus kisutchi (Yasutake and Wood, 1957) was...

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...

Resource allocation in four syntopic species of marine diving birds

Creator:: Scott, James Michael, 1941-
Abstract:: During 1969-1971 I studied patterns of resource allocation and behavioral interaction among Brandt's Cormorants, Pelagic Cormorants, Common Murres and Pigeon Guillemots in the area of a breeding colony on Yaquina Head on the central Oregon coast. Extensive studies of the breeding colony were combined with detailed observations of the distribution,...
