Revision of Wyeomyia (Hystatomyia) Dyar & Knab (Diptera: Culicidae: Sabethini

Creator:: Adkins, Jessica Y.
Abstract:: Members of the tribe Sabethini (Diptera: Culicidae) oviposit and develop in phytotelmata (plant-held waters) and are primarily distributed in a pantropical pattern. Recent cladistic studies have demonstrated that while the tribe is monophyletic, three of its 13 genera are not. The genus Wyeomyia is particularly problematic and debate among culicidologists...

Trophically transmitted parasites as ecosystem indicators : relationships among parasite community structure, juvenile salmon diet composition, and ocean conditions

Creator:: Losee, James P.
Abstract:: Recent research conducted throughout the Northern California Current (NCC) on the ecology of Pacific salmon (Oncorhynchus spp.) indicates that variable ocean conditions affect the community composition of zooplankton in the nearshore environment which, in turn, can affect the quality of prey for fish, sea birds and mammals. Interannual variability in...

Re‐establishment of the native oyster, Ostrea conchaphila, in Netarts Bay, Oregon, USA

Creator:: Archer, Pamela Emily
Abstract:: Olympia oysters, “Ostrea conchaphila,” were once common along the west coast of North America. A popular delicacy, native oyster populations began to decline in the late 1800’s due to over‐harvest, degraded water quality, and habitat loss. Interest in re‐establishing the native oyster in a small Oregon estuary, Netarts Bay, culminated...

A comparison of early marine residence in hatchery and natural Chinook salmon (Oncorhynchus tshawytscha)

Creator:: Claiborne, Andrew M.
Abstract:: The mechanisms of mortality during critical life stages of fish are not well-understood and, for many species, it is not clear if the mechanisms are similar for naturally and artificially propagated individuals. For Chinook salmon (Oncorhynchus tshawytscha), natural fish potentially face negative interactions, such as competition, and survival disadvantages, such...

College students' multiracial identity perceptions and experiences of programs and associations

Creator:: Plaza, Lauren S.
Abstract:: This thesis examined the identity transitions that occurred prior to enrollment at a predominantly, White, large, public research university and after completing at least one year of college for students who identify as multiracial. As a secondary purpose, this thesis also examined whether these students sought support through groups that...

Mentoring student leaders of color

Creator:: White, Leann E.
Abstract:: Involvement in student leadership provides opportunities for student development (Foubert and Grainger, 2006) and is linked with higher rates of persistence (Astin, 1984), making leadership programs an important tool for increasing the retention and success of students of color. Unfortunately, traditional leadership paradigms often used in student leadership programs are...

Spatiotemporal Drivers of Seabird Distribution at the Pacific Marine Energy Center off Newport, Oregon

Creator:: Porquez, Jessica M.
Abstract:: The central Oregon coast was selected as an ideal site for wave energy development and establishment of the Pacific Marine Energy Center (PMEC). PMEC will consist of two nearshore sites, one north (NETS) and one south (SETS) of the Yaquina River, Oregon. Our study aims to assess how the development...

Ecological Consequences of Marine Debris: Understanding Large-Scale Species Transport on Tsunami Debris and Research Priorities in Oregon

Creator:: Gillman, Reva A.
Abstract:: The release of marine debris into the oceans and seas is a global issue of growing concern. These materials are harmful to marine environments and can also transport non-native species to novel habitats. Non-native species floating on marine litter is one of the lesser known impacts associated with marine debris....

Evaluation of Pacific Lamprey Entosphenus Tridentatus Anatomical Structures as Records of Age and Isotope Histories

Creator:: Pelekai, Keala N.
Abstract:: The anadromous Pacific Lamprey (Entosphenus tridentatus) is a biologically and culturally important species native to the North Pacific Ocean and its adjacent freshwater tributaries. Pacific Lamprey have experienced declines in abundance and distribution throughout their native range, highlighting a need for further research on the species to better inform conservation...

Year-class regulation of mid-upper Columbia River spring Chinook salmon Oncorhynchus tshawytscha : the role of juvenile size, growth, and migratory behavior

Creator:: Tomaro, Londi M.
Abstract:: Early ocean residence is assumed to be a critical period for juvenile Pacific salmon Oncorhynchus spp. However, the specific mechanisms influencing growth and survival in the ocean have not been identified for most populations. Therefore, three hypotheses regarding the relationship between early marine residence and subsequent survival of mid-upper Columbia...
