Terrestrial amphibian distribution, habitat associations and downed wood temperature profiles in managed headwater forests with riparian buffers in the Oregon Coast Range

Creator:: Kluber, Matthew R.
Abstract:: Western forests have become increasingly fragmented landscapes dominated by young stands. Given that western Oregon forests largely consist of headwater systems, there is a need to better understand how headwater forest taxa and their habitats are impacted by forest management practices. Several amphibian species associated with forested headwater systems have...

Diversity and community structure of aquatic insects in isolated montane desert streams

Creator:: Bogan, Michael T.
Abstract:: Local aquatic insect diversity and community structure is the result of multiple local and regional factors, and observed patterns depend upon the spatial and temporal scale under examination. Isolated stream systems in arid regions represent a new challenge in understanding the drivers of diversity and community structure, as most studies...

Pool habitat characteristics and juvenile anadromous salmonids in two Oregon coastal streams

Creator:: Haapala, Deborah L.
Abstract:: Relations between the diversity of juvenile anadromous salmonids and pool features were examined in a managed and a pristine watershed in Oregon during the summer of 1990. There were no differences (p>0.05) in pool depth, velocity or pool wood volumes between streams. However, the pristine system had twice the number...

Drought, dispersal, and community dynamics in arid-land streams

Creator:: Bogan, Michael T.
Abstract:: Understanding the mechanisms that regulate local species diversity and community structure is a perennial goal of ecology. Local community structure can be viewed as the result of numerous local and regional processes; these processes act as filters that reduce the regional species pool down to the observed local community. In...

Surfgrasses (Phyllospadix spp.) as dynamic foundation species for macroinvertebrates along the Oregon coast

Creator:: Moulton, Orissa M.
Abstract:: Foundation species are important components of ecosystems because they provide habitat and ameliorate stressful conditions for residents. This thesis considers the role of surfgrasses (Phyllospadix spp.) as dynamic foundation species on the coast of Oregon in two studies. Chapter 2, which presents an observational survey of two Phyllospadix congeners, investigates...

A satellite-derived climatology of global ocean winds

Creator:: Risien, Craig Miller
Abstract:: A satellite-derived Climatology of Global Ocean Winds (COGOW) on a 0.5° latitude by 0.5° latitude grid is presented based on 5-years (August 1999 July 2004) of measurements from the SeaWinds scatterometer that was launched on 19 June 1999 onboard the QuikSCAT satellite. SeaWinds is an active microwave radar that estimates...

Evaluating benthic macroinvertebrates as bio-indicators of freshwater habitat quality in an eastern Oregon agro-ecosystem

Creator:: Scherr, Melissa A.
Abstract:: The effect of anthropogenic disturbance on river systems is gaining attention, and concerns about the state of freshwater natural resources are increasing globally, as are efforts to restore habitat that has been degraded by disturbance. In rivers, non-point source pollution affects the physical characteristics of the habitat and the endemic...

Treatment of dairy wastewater in a constructed wetland system : evapotranspiration, hydrology, hydraulics, treatment performance, and nitrogen cycling processes

Creator:: Niswander, Steven Francis
Abstract:: Five unique but related studies were conducted at the Oregon State University Dairy Wetland Treatment System (OSUDWTS), Corvallis, OR. The research site consisted of six parallel wetland cells, which were built in 1992 and began receiving concentrated dairy wastewater in the fall of 1993. Hydrologic, hydraulic, and water quality data...

Biophysical factors driving the distribution and abundance of redband/steelhead trout (Oncorhynchus mykiss gairdneri) in the South Fork John Day River Basin, Oregon, USA

Creator:: Madriñán, Luis Francisco
Abstract:: The overall goal of this study was to identify multiple scales of habitat use and habitat electivity by redband/steelhead trout and define the limiting factors affecting the distribution patterns of this species during summer flows. The main objective in chapter 2 was to identify the most important habitat associations that...

Meander scars : reflections on healing a river

Creator:: Metzger, Abby P.
Abstract:: As Europeans settled the Willamette Valley in the 1800s, they began to simplify Oregon's largest river contained wholly within state boarders—the Willamette. The river lost miles of channels from dikes, dams, and development. Some channels vanished under concrete. Others became meander scars, or shallow, dry depression in the land where...
