Conditioning of northern Great Basin grasses with livestock grazing

Creator:: Aguilera, Lisa M.
Abstract:: Because forage quality of cool season grasses declines to sub-maintenance levels for ruminants late in the growing season in the northern Great Basin, there is a need to elevate protein levels and digestibility of grasses for both wild and domestic ruminants in late summer. Anderson and Scherzinger (1975) proposed using...

Invertebrate composition and distribution in desert springs of Oregon

Creator:: Mauger, Susan
Abstract:: In the summers of 1998 and 1999, aquatic invertebrate and plant communities were sampled from nineteen springs in the Warner Basin of southeastern Oregon. Across the landscape, these springs exhibited a broad range in water temperature (5-24°C), pH, conductivity, elevation, and gradient. Within a particular spring, water temperature and chemistry...

Intrinsic and extrinsic quality of West Coast albacore tuna (Thunnus alalunga)

Creator:: Wheeler, Sena C.
Abstract:: The purpose of this study is to identify the intrinsic and extrinsic quality characteristics of West Coast albacore tuna (Thunnus alalunga). Albacore tuna were troll caught off the Oregon coast and transferred to the Oregon State University Seafood laboratory in Astoria, Oregon. Core samples were extracted from six designated body...

The short term temporal and spatial variability of nitrogen and phosphorus in two Oregon Coast Range streams

Creator:: Scherer, Robert A.
Abstract:: High intensity sampling was undertaken to characterize the temporal and spatial variability of oxidized nitrogen (NO3-N + NO2-N), ammonia-nitrogen (NH3-N), total dissolved phosphorus, total unfiltered phosphorus and orthophosphorus (PO4-P) from two adjacent small streams in Western Oregon's Coast Range, Deer Creek (303 ha) and Flynn Creek (203 ha). Deer Creek...

Soil engineering properties and vegetative characteristics for headwall slope stability analysis in the Oregon coast range

Creator:: Bransom, Mark
Abstract:: Six headwalls in the central Oregon coast range were selected for study of soil engineering properties and vegetativecharacteristics important for analysis of slope stability. The headwalls were considered representative of those which would be candidates for timber leave areas due to geomorphic and topographic features, including steepness of slope and...

Arthropod community structure in regenerating Douglas-fir and red alder forests : influences of geography, tree diversity and density

Creator:: Schaerer, Brett L.
Abstract:: The structuring of canopy arthropod communities was reviewed and investigated in relation to tree species diversity and its component factors, interspersion of different species and density of each tree species. Fifteen treatments of Douglas-fir (Pseudotsuga menziesii) and red alder (Alnus rubra) (various densities and proportions of each) were randomly assigned...

Chemical and physical properties of Douglas fir bark relevant for the production of container crops in Oregon

Creator:: Buamscha, Maria Gabriela
Abstract:: It is widely accepted among nursery producers that [Pseudotsuga menziesii (Mirbel) Franco] bark (DFB) is an excellent substrate for container production, hence its widespread use in Oregon and other regions where Douglas fir constitutes a significant portion of the forest products industry. Despite its widespread use, little information is available...

Variation and heritability of vegetative, reproductive and fruit chemistrytraits in black raspberry (Rubus occidentalis L.)

Creator:: Dossett, Michael
Abstract:: In recent years, there has been renewed interest in black raspberry (Rubus occidentalis L.) breeding. This has been spurred by an increase in black raspberry consumption due to studies that have shown them to be particularly high in anthocyanin content indicating high levels of antioxidants. Present cultivars are ill adapted...

Autonomous in situ measurements of estuarine surface PCO₂ : instrument development and initial estuarine observations

Creator:: Wall, Colleen McKay
Abstract:: A novel, low-cost instrument capable of measuring surface water PCO₂ was designed for use in dynamic, shallow-water environments. The instrument was tested in the Yaquina River Estuary, a macrotidal estuary known to experience a wide range of conditions ranging from dominance by the coastal ocean during summer upwelling to substantial...

Geochemical characteristics of iron-manganese nodules in seasonally-saturated soils of the Willamette Valley, Oregon

Creator:: Seter, Lisa M.
Abstract:: This study was initiated to characterize the distribution of Fe-Mn nodules and to elucidate trends of Fe, Mn, and P relative to the intensity of the annual cycles of reduction and oxidation. Nodules were enriched in Fe, Mn, and P relative to the soil matrix making them an integral part...
