The species composition, density, and distribution of the littoral zooplankton assemblage in Crater Lake, Oregon

Creator:: Warncke, William Madara
Abstract:: The species compositions and densities of the littoral and pelagic zooplankton assemblages in Crater Lake were compared. The littoral and pelagic zooplankton assemblages of most lakes are typically different due to different habitat conditions in the two zones. The littoral zone of Crater Lake lacks many of the habitat characteristics,...

Seasonal floodplain wetlands as fish habitat in Oregon and Washington

Creator:: Baker, Cynthia F.
Abstract:: To begin to understand freshwater seasonal floodplain fish communities in the context of human alteration of the physical system, species introductions and wetland restoration efforts, I studied fish assemblages in fifteen seasonal floodplain wetlands within four geographic regions (coastal, upper Columbia River estuary, Puget Sound and eastern Oregon/Washington) in the...

Marine Neritic and Epipelagic Community Dynamics: An Investigation of the 'Yin' and 'Yang', No-Analog, and Refugia from a Multi-species Perspective

Creator:: Barceló, Caren
Abstract:: Changes in ocean conditions influenced by climatic fluctuations have lead to changes in individual species distributions, which alter the diversity, communities and species interactions across marine ecosystems worldwide. Assessing the species composition and identifying regions and habitats that can safeguard the persistence of biota are critically important. In this dissertation,...

Vertebral elemental markers in elasmobranchs : potential for reconstructing environmental history and population structure

Creator:: Smith, Wade D.
Abstract:: Differences in the chemical composition of calcified structures can be used to reveal natal origins, connectivity, metapopulation structure, and reconstruct the environmental history or movement patterns of many marine organisms. Sharks, skates, and rays (elasmobranchs) lack the calcified structures, known as otoliths, that are typically used for geochemical studies of...

Patterns of distribution, abundance, and change over time in the marine bird community of Prince William Sound, Alaska, 1989-2012

Creator:: Cushing, Daniel A.
Abstract:: Over recent decades, the marine ecosystems of Prince William Sound (PWS), Alaska have experienced the concurrent effects of a major anthropogenic disturbance, the 1989 Exxon Valdez oil spill (EVOS), and a dynamic atmospheric-oceanic environment. Studies of top marine consumers can provide insights into processes of ecosystem change. Using data collected...

Ecological Consequences of Marine Debris: Understanding Large-Scale Species Transport on Tsunami Debris and Research Priorities in Oregon

Creator:: Gillman, Reva A.
Abstract:: The release of marine debris into the oceans and seas is a global issue of growing concern. These materials are harmful to marine environments and can also transport non-native species to novel habitats. Non-native species floating on marine litter is one of the lesser known impacts associated with marine debris....

Comparative study of the population dynamics, secondary productivity, and reproductive ecology of the euphausiids Euphausia pacifica and Thysanoessa spinifera in the Oregon upwelling region

Creator:: Gutierrez, Jaime Gomez
Abstract:: I compare the seasonal abundance variation, population dynamics, fecundity, egg hatching mechanism and success, and apostome ciliate parasites of the euphausiids Euphausia pac?fica and Thysanoessa spinfera from the Oregon coast, USA. Community structure and nearshore distributions were examined from bi-weekly oceanographic surveys (1970-1972). This region has a strong cross-shelf change...

Impacts of dredged material disposal on estuarine benthic macrofaunal communities in Coos Bay, Oregon

Creator:: Erman, Lisa T.
Abstract:: Hopper dredge disposal of coarse grained sediment was investigated between May and September, 1986, at a designated disposal area, Site G, in Coos Bay, Oregon. The objectives of the study were to: (a) identify and describe the benthic macrofaunal community structure at Site G during May and September, 1986; (b)...
