Residence and growth of juvenile chum salmon (Oncorhynchus keta) in Netarts Bay, Oregon

Creator:: Wilson, Matthew T.
Abstract:: Estuarine residence and growth of juvenile chum salmon (Oncorhynchus keta) from Netarts Bay, Oregon were estimated from daily-formed growth increments of sagittal otoliths which are distinguishable from accretion patterns formed during freshwater residence. Estuarine residence time was inversely related to the average size at which juvenile chum salmon entered Netarts...

Glass capillary gas chromatographic analysis for trace amounts of cyclopropenoid fatty acids

Creator:: Ryan, Daberath
Abstract:: Dietary cyclopropenoid fatty acids (CPFA) have long been known to cause pronounced physiological disorders in both farm and laboratory animals. Past work has shown CPFA to be a powerful promoter of carcinogenesis in trout, rats and mice. Sterculic and malvalic acids (CPFA's) are found in seed lipids of plants from...

Deposition and characterization of transition metal oxides from aqueous solution

Creator:: Betterton, Sharon A.
Abstract:: The aqueous chemistries of two transition metal cations, Zr⁴⁺ and Nb⁵⁺, are examined and then used to develop inorganic precursor solutions. The oxides of these cations (ZrO₂ and Nb₂O₅) are deposited and characterized, and their morphological and optical properties discussed. Due to the obstacles created by niobium's aqueous chemistry, an...

Effect of sucrose on the production of flavor compounds by yogurt culture bacteria

Creator:: Yang, Chang-su
Abstract:: Organoleptically, flavored yogurts appear to contain lower levels of acetaldehyde than plain yogurt. This study was undertaken to seek the reasons for this phenomenon by focusing on the analyses of acetaldehyde production by yogurt culture bacteria in yogurt base containing added sucrose and by performing other analyses such as the...

Making the Connection: Linking Stress Physiology of Juvenile Northern Spotted Owls to Environmental Variation and Long-term Survival

Creator:: Mikkelsen, Ashlee J.
Abstract:: The northern spotted owl (Strix occidentalis caurina; spotted owl) is of conservation concern and endemic to mature forests of the Pacific Northwest. Adult survival has a strong effect on population growth rate, but juvenile survival and recruitment are also important components of population change. Despite the importance of this life...

The Role of Grazing and Weather in Nest Predator-Prey Dynamics and Reproductive Success of Sagebrush-obligate Songbirds

Creator:: Schroeder, Vanessa M.
Abstract:: Livestock grazing occurs worldwide, spanning over 25% of land globally. Effective conservation of biodiversity relies upon understanding the interactions of agricultural management practices and increasingly variable weather associated with climate change. I evaluated grazing, weather and predator-prey interactions within a grazing experiment in the sagebrush ecosystem of southeastern Oregon. I...

Diel Rest Structure Selection and Multiscale Analysis of Pacific Marten Resting Habitat in Lassen National Forest, California

Creator:: Tweedy, Patrick J.
Abstract:: Forests in the western United States have changed drastically over the past 150 years given a long history of utilization (harvest and grazing) and associated fire exclusion. These actions have altered the composition and structure of these forests as well as affected ecosystem function. Current policies for federal land management...

Nitrogen 15 studies with nonleguminous nitrogen-fixing plants

Creator:: Webster, Stephen Russell
Abstract:: Snowbrush (Ceanothus velutinus), red alder (Alnus rubra), and bitterbrush (Purshia tridentata) are three important nitrogen- fixing nonleguminous species. They commonly grow in association with commercially important conifers in western United States and conceivably could be utilized to add nitrogen to forest ecosystems. Nitrogen 15 gas was used to study nitrogen...
