Spatial and temporal variations in respiration rates and hypoxia on the Oregon shelf

Creator:: Wolf, Megan J.
Abstract:: Inner shelf hypoxia has occurred along the Oregon coast between the latitudes 44ºN and 45ºN since 2002 with increasing duration and intensity, posing a threat to marine life. The objective of this research was to determine whether variation in respiration rate explains spatial and temporal variation in hypoxia. Dissolved oxygen...

Human Visitation in the Rocky Intertidal and its Effects on Abundance of Algal and Invertebrate Species

Creator:: Silbernagel, Justin J.
Abstract:: The rocky intertidal is a diverse ecosystem with a variety of species and ecological interactions. Many biotic and abiotic interactions act together to restrict the abundance and distribution of species. Anthropogenic effects can have an important impact on species abundance and distribution as well. This study looks at how human...

The Predictability of Qualitative Food Web Dynamics in Response to Extinction and Invasion

Creator:: Rockow, David J.
Abstract:: Food webs are extraordinarily complex, containing myriad direct interactions and indirect effects. Determining how this network of interactions and effects influences a food web’s qualitative dynamics is a challenging task, especially because data on food web structure and individual interaction strengths is unknown in virtually all real-world ecosystems. The goal...

Marine reserves in The Bahamas and Ecuador : a scientific and socioeconomic perspective

Creator:: Lamb, Robert W.
Abstract:: Marine reserves are known to directly replenish overfished species. However, the community-wide effects of reserves are less clear. I examined the community of coralreef fishes in a large, fully protected marine reserve in The Bahamas: the Exuma Cays Land and Sea Park. Visual-transect surveys provided estimates and comparisons of the...

Coral-reef fishes : insights into larval dispersal and invasion ecology

Creator:: Pusack, Timothy J.
Abstract:: Because many coral-reef fishes are observable in situ, are amenable to transplantation, have small home ranges and short generation times, they provide a excellent system to investigate many topics within general ecology, fisheries biology, and conservation biology. The primary goal of this dissertation was to use the coral-reef fishes system...

Early succession in beds of the red alga, Iridaea cornucopiae Post. & Rupr. (Gigartinaceae) : alternate pathways

Creator:: Olson, Annette M.
Abstract:: Multiple successional sequences have been observed following disturbance in communities on marine hard substrata. Observations of the turf-forming alga, Iridaea cornucopiae Post. & Rupr. (Gigartinaceae), suggest that I. cornucopiae may assume its dominance by its ability to vegetatively pre-empt space. High limpet densities in the natural community, suggest that I....

The biology of a shallow-water methane vent

Creator:: Juhl, Andrew R.
Abstract:: In September of 1989, the site of an active seafloor methane vent was confirmed approximately 20 km off the coast of Oregon in shelf waters 135 m deep. The location of the vent had been described to Oregon State University oceanographers by a local commercial fisherman. Preliminary observations in 1989...

Movement Patterns of Rockfishes at the Redfish Rocks Marine Reserve, Oregon

Creator:: Calvanese, Thomas P.
Abstract:: The effects of Marine protected areas (MPAs) on adult fish populations depend on the degree of protection provided, which is partly a function of MPA size and the spatial extent of fish movements. The Redfish Rocks Marine Reserve (RRMR) and MPA, located on the south coast of Oregon near Port...
