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...

The Influence of Prey Predictability on the Foraging Behavior and Movement of Intertidal Predators

Creator:: Hennessey, Shannon M.
Abstract:: Fluctuations and spatial heterogeneity of habitat and resources is thought to underlie niche variation in animal populations, with intraspecific differences serving to produce or maintain population-, community-, or ecosystem-level patterns. Individual diet variation, defined as individual variation in food resource use within a population that is consistent over time, is...

The effects of pathogens, UV-B radiation, and introduced species on amphibians in the Pacific Northwest

Creator:: Kiesecker, Joseph Michael
Abstract:: I examined two amphibian communities to assess factors that may impact amphibian biodiversity. The results suggest that the potential factors which influence the maintenance of amphibian biodiversity are multi-faceted and thus, attempts to understand these factors must reflect these complexities. I investigated factors that influenced the susceptibility of western toad...

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...

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...

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...

Population and production ecology of Lipsothrix spp. (Diptera:Tipulidae)

Creator:: Dudley, Thomas L.
Abstract:: Craneflies of the genus Lipsothrix inhabit decomposing wood in streams. The life cycles and ecological relationships of L. nigrilinea (Doane) and L. fenderi Alexander were investigated to determine how they exploit and respond to the wood habitat and their role in degradation of woody debris in western Oregon. Surveys of...

Population and community ecology of the red alga Rhodomela larix (Turner) C. Agardh, on the central Oregon coast

Creator:: D'Antonio, Carla Marie, 1956-
Abstract:: Aspects of the life history and ecology of the intertidal turf-forming alga Rhodomela larix (Turner) C. Agardh were examined over a two year period at several sites on the Oregon coast. Rhodomela occurred over a broad tidal range and exhibited different growth and morphology characteristics with respect to tidal height....

Multiple stressors and amphibian population declines

Creator:: Hatch, Audrey C.
Abstract:: In the past decade, declines in amphibian populations have captured scientific and popular interest. The causes of the declines are likely to be complex and involve interactions between several environmental stressors. Using multifactorial experiments, I investigated the combined effects of several anthropogenic stressors on developing amphibians in Oregon, USA. In...
