Indirect effects of ultraviolet-B radiation on larval amphibians as mediated by food quality and trophic interactions

Creator:: Scheessele, Erin A.
Abstract:: Ultraviolet-B radiation (UVB) is an abiotic stressor in both terrestrial and aquatic systems. The stratospheric ozone layer, depleted due to anthropogenic activities and the cause of elevated UVB at earth's surface over the last four decades, is predicted to recover by 2065. However, UVB levels in aquatic systems may continue...

The ecological and behavioral dynamics of breeding in three sympatric anuran amphibians

Creator:: Olson, Deanna H.
Abstract:: Breeding ecology and behavior were investigated in a field study of three sympatric anuran amphibians in the Oregon Cascade Mountains: the western toad (Bufo boreas), the Cascades frog (Rana cascadae) and the Pacific treefrog (Hyla regilla). A comprehensive study of the western toad mating system was conducted at three populations...

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...

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...

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...

Formation and maintenance of fish assemblages in a high desert Oregon stream

Creator:: Pearsons, Todd N.
Abstract:: Considerable controversy exists about how fish assemblages are organized. I explicitly took fish movement into account while I studied the effects of disturbance, habitat complexity, and predation at different times of the summer to understand the major factors influencing assemblage structure in a high desert Oregon stream. The effects of...

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...

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...
