Growth of juvenile Pacific oysters, Crassostrea gigas (Thunberg) and Manila clams, Tapes japonica (Deshayes) in effluent from salmon-macroalga polyculture system

Creator:: Diaz, Maria Elena, 1958-
Abstract:: Experiments were carried out in fall and winter, 1990 and spring and summer, 1991 , to determine growth and mortality of juvenile Pacific oysters {Crassostrea gigas) in effluent from cultured coho salmon {Oncorhynchus kisutch) , and effluent from salmon in which the red macroalga Palmaria mollis was cultured. Ambient sea...

Hydrologic and vegetation responses associated with restoration of wetlands in the Willamette Valley, Oregon

Creator:: Coleman, Gregory A.
Abstract:: I examined hydrological and plant community changes associated with the implementation of a restoration management plan in two riparian meadows located within an agricultural landscape of the central Willamette Valley, Oregon. I established exclosure fencing (a form of passive restoration) in one agricultural field and established fencing and plugged a...

Effects of Synchronous Low Flow and Temperature Maxima on Coastal Cutthroat Trout and Coastal Giant Salamander: An Experimental Approach

Creator:: Tinoco Pickens, Francisco Andrew
Abstract:: As regional climates warm in the Pacific Northwest, USA, flow minima and temperature maxima may become more synchronous in headwater streams over time. The dual stresses from lower flows and warmer temperatures will be energetically costly for cold-water species such as Coastal Cutthroat Trout and Coastal Giant Salamander. Individual fates...

Riparian vegetation composition and structure associated with channel morphology of headwater meadow streams in the Blue Mountains, northeast Oregon

Creator:: Toledo, Zachary O.
Abstract:: Relationships between the structure and composition of riparian vegetation with channel morphology were examined in three montane meadow streams in the headwaters of the Upper Grande Ronde River and North Fork John Day River in the Blue Mountains, northeast Oregon. Vegetation composition, root biomass, and channel morphology cross-sections were sampled...

The Soundcheck of the Sea : Comparing Marine Soundscapes on a Continental Scale

Creator:: Haver, Samara M.
Abstract:: Monitoring marine ambient sound using standardized methods supports assessments of ocean sound levels across widespread ecosystems. This thesis quantifies differences among coastal and deep-water marine soundscapes in the Atlantic and Pacific oceans. The sources of sound in a soundscape are compartmentalized into three components and compared over time and among...

Phylogeography and population genetic structure of double-crested cormorants (Phalacrocorax auritus)

Creator:: Mercer, Dacey M.
Abstract:: The Double-crested Cormorant (Phalacrocorax auritus) is a widespread, colonial, North American waterbird with bicoastal and inland distributions. Four subspecies have been described within North America corresponding to five geographic breeding regions: Interior and North Atlantic cormorants (P. a. auritus); Southeastern cormorants (P. a. floridanus); Alaskan cormorants (P. a. cincinnatus); and...

Fine scale foraging behavior of gray whales in relation to prey fields and vessel disturbance along the Oregon Coast

Creator:: Sullivan, Florence A.
Abstract:: The desire to understand the spatial and temporal drivers of animal behavior and distribution relative to scale is central to movement ecology. Optimal foraging theory states that a predator should continue exploiting a patch until it is no longer profitable to do so. As human developments increasingly encroach on the...

Vegetation and Small Mammal Responses to Western Juniper (Juniperus occidentalis) Control in Eastern Oregon

Creator:: Morozumi, Corinne N.
Abstract:: Shrub-steppe ecosystems of western North America provide habitat for many wildlife species, are important components of public and private rangelands, and offer recreational opportunities for millions of people. They are some of the most vulnerable ecosystems in the United States and have been altered by human activities such as livestock...

Evaluating the fatty acid signature technique for studies of diet composition inpiscivorous waterbirds

Creator:: Myers, Anne Mary
Abstract:: This research was designed to evaluate the Fatty Acid Signature (FAS) technique as a non-lethal alternative to more traditional, and sometimes destructive, methods of studying the diet composition of piscivorous birds. Specifically we tested the technique with Caspian terns (Hydroprogne caspia) which currently nest in large numbers in the Columbia...
