Aquatic insect adaptations to different flow regimes

Creator:: Yamamuro, Asako Melody
Abstract:: My thesis explored the effects of environmental variability on population dynamics and community composition of aquatic insects. Environmental variability in the form of flow regime in streams can limit the distribution and life-history traits of aquatic insects. I used tributaries to the McKenzie River in Oregon with dramatically different flow...

Early events in hydrocortisone induced glutamine synthetase activity in differentiating chick neural retina

Creator:: Hull, Shirley Anne
Abstract:: Glutamine synthetase in the embryonic chick neural retina shows a 50 fold increase in activity between the 16th and 17th day of embryonic development. This increase in enzyme activity results from de novo enzyme synthesis thus making it a useful marker of differential gene expression. A precocious rise in activity...

The oplophorid and pasiphaeid shrimp from off the Oregon coast

Creator:: Forss, Carl Albert
Abstract:: The 13 species of shrimps studied for this thesis were collected off the Oregon coast. The family Oplophoridae is well represented in this area. Five of the seven known genera were identified. Hymenodora frontalis, H. glacialis, and H. gracilis were described and further differentiating characters were illustrated. Other members of...

The effects of community composition, landscape structure, and climate on host-pathogen interactions

Creator:: Moore, Sean M.
Abstract:: Like other species interactions in ecological systems, host-pathogen interactions are influenced by environmental factors, landscape characteristics and the broader community context. My thesis explores the potential influences of food-web interactions (Chapter 2), climate change (Chapter 3), landscape structure and host movement patterns (Chapter 4), and the combined influences of local...

Geographic variation and systematics of the western Plethodon

Creator:: Brodie, Edmund D.
Abstract:: The western Plethodon include vandykei vandykei, v. idahoensis, larselli, dunni,vehiculum, stormi, elongatus, and an undescribed form referred to as the "unstriped" Plethodon. These salamanders have been placed into three species groups: the Vandykei group, the Vehiculum group, and the Elongatus group. Range maps are provided and geographic variation is discussed...

The influence of biophysical feedbacks and species interactions on grass invasions and coastal dune morphology in the Pacific Northwest, USA

Creator:: Zarnetske, Phoebe Lehmann
Abstract:: Biological invasions provide a unique opportunity to study the mechanisms that regulate community composition and ecosystem function. Invasive species that are also ecosystem engineers can substantially alter physical features in an environment, and this can lead to cascading effects on the biological community. Aquatic-terrestrial interface ecosystems are excellent systems to...

Patterns of macrophyte wrack deposition on sandy beaches of the Pacific Northwest coast, U.S.A.

Creator:: Reimer, Jessica N.
Abstract:: Dislodged macroalgae and seagrasses, also known as marine wrack, frequently wash into coastal ecosystems from the ocean and are potentially important ecological resources for biological communities. These!nutrient and organic matter subsidies may be especially important on sandy beaches, where little in situ primary productivity exists for higher trophic levels. To...
