Patterns of coastal cutthroat trout survival in two headwater stream networks

Creator:: Berger, Aaron M.
Abstract:: Mark-recapture methods were used to examine watershed-scale survival rates of coastal cutthroat trout (Oncorhynchus clarkii clarkii) from two headwater stream networks located in the foothills of the Cascade Mountain Range, Oregon. Differences in survival were explored among spatial (stream segment, stream network [main stem or tributaries], and watershed) and temporal...

The Role of Emerging Pathogens in Amphibian Population Declines : Experimental Evidence

Creator:: Hambalek, Natalie M.
Abstract:: Rapid rates of biodiversity loss have supported the notion that Earth is experiencing a sixth major extinction event. The causes of worldwide biodiversity loss are multifaceted and context dependent. One of the most prominent groups experiencing population declines and extinctions are amphibians. Several pathogens and their associated diseases are especially...

Effect of nitrogen rates, row spacings and population densities on yield and ear characteristics of sweet corn

Creator:: Yassen, Abdulameir Ali
Abstract:: The response of sweet corn Zea mays L. var. rugosa (cultivar 'Jubilee') to row spacing, nitrogen and population density at two planting dates was studied in a field experiment at the OSU Vegetable Research Farm in 1984. Variables included two row spacings, 75 cm and 90 cm, three nitrogen rates,...

Effects of Whey Protein Consumption on Inflammatory Biomarker Levels in Healthy Older Adults

Creator:: Adler, Samuel
Abstract:: Whey protein’s potential for bioactivity is well documented, but there is disagreement on the extent to which it may modulate the immune system towards decreased inflammation. Decreased inflammation is generally perceived as a beneficial bioactivity in foods as excessive chronic inflammation is linked to morbidity and mortality. This thesis first...

Holocene accumulation rates of pelagic sediment components in the Panama Basin, Eastern Equatorial Pacific

Creator:: Swift, Stephen Atherton
Abstract:: Holocene bulk sediment and component accumulation rates were measured in twenty-eight piston and gravity cores taken from the floor of the western Panama Basin and on the surrounding ridges. Radiocarbon ages and oxygen isotope curves provided Holocene age control in nine cores. Time datums in nineteen other cores were inferred...

A comparison of porous polymers used in collecting organic volatiles in foods

Creator:: Boyko, Alayne Linda
Abstract:: Porapak Q, Chromosorb 102, and Tenax GC, three porous polymers commonly used as adsorbents in headspace analyses were investigated. The retention times of various low-boiling compounds relative to water were measured on the collection columns to determine which compounds would be lost during the water removal step employed after sampling...

Seasonal Movement of Coastal Cutthroat Trout (Oncorhynchus clarkii clarkii) in Headwater Streams in Oregon

Creator:: Linkem, Christina N.
Abstract:: Headwater streams in the Oregon Coastal Range are subject to drastic fluctuations in flow and temperature because of the changing seasonality of a Mediterranean climate. In response to these changes, stream fishes exhibit a variety of movement patterns. Coastal Cutthroat Trout (Oncorhynchus clarkii clarkii) have evolved an assortment of life...

Surface sediments of the Panama Basin : coarse components

Creator:: Kowsmann, Renato O.
Abstract:: The abundance and distribution of biogenic, terrigenous and volcanic particles in the Panama Basin are markedly dependent on bottom topography and dissolution of calcite in the deeper parts of the basin. Of the coarse fraction (>62μ), foraminiferal tests and acidic volcanic glass shards are concentrated on the Cocos and Carnegie...

Effects of wildfire on growth and demographics of coastal cutthroat trout in headwater streams

Creator:: Heck, Michael P.
Abstract:: Wildfire is a largely terrestrial perturbation broadly recognized as an agent of disturbance and ecological change in forested biomes. Effects of post-fire conditions on biotic components of aquatic systems have been less well-documented, although hypothetically, the two are strongly connected. In fact, the influence of wildfire may be most profound...

The influence of supplemental alfalfa quality on the intake and utilization of low-quality roughages by beef cattle

Creator:: Weder, Christoph E.
Abstract:: Three experiments were conducted to evaluate the influence of quality of supplemental alfalfa quality on beef cattle consuming low-quality meadow grass (MG) roughages. Fifteen steers (250 kg) were assigned randomly to one of three treatments: 1) meadow grass (5.2% CP), no supplement (MNS); 2) meadow grass plus high quality alfalfa...
