Seismicity at the Cascadia plate boundary beneath the Oregon continental shelf

Creator:: Williams, Mark Charles
Abstract:: Since 2003, 39 small earthquakes have been detected offshore central Oregon in the nominally locked part of the Cascadia subduction zone, where very little seis- mic activity has been recorded in spite of a paleo-seismic record of great subduction events. Although the regional earthquake bulletin reports depths of 29 and...

Utilizing cooperative fisheries research to monitor and understand harmful algal blooms along the Oregon coast

Creator:: Gilliland, Raquel C.
Abstract:: Harmful algal blooms (HABs) are a problem for coastal communities, the fishing industry, and coastal organisms. Pseudo-nitzschia spp. is a regularly occurring diatom in Oregon’s coastal waters. At times, Pseudo-nitzschia spp. can facultatively produce domoic acid, a neurotoxin that can bioaccumulate in the food chain. While regular shore-based sampling provides...

Spatial and Temporal Assessment of Vertically Migrating Myctophids as Biotransporters of Microplastics to Mesopelagic Food Webs

Creator:: Boisen, Olivia C.
Abstract:: It is well documented that microplastics and semi-synthetic particles (<5 mm) pervade the marine environment, with their ingestion by marine fauna eliciting global concern. While fishes exposed to microparticles in a laboratory setting have exhibited both sub-lethal and lethal effects, the diversity in material, morphology, and size of these contaminants...

Growth, residence, and movement of juvenile Chinook salmon within restored and reference estuarine marsh channels in Salmon River, Oregon

Creator:: Hering, David K.
Abstract:: Tidal wetland channels provide rearing habitat for juvenile Chinook salmon as they emigrate from freshwater habitat and prepare to enter the ocean. Widespread diking and drainage of estuarine marshes for agricultural and urban development may have contributed to a decline in salmon abundance in the Pacific Northwest, prompting efforts to...

Encounter norms of snorkelers and scuba divers at Molokini, Hawai'i : methodological and managerial applications

Creator:: Bell, Caitlin M.
Abstract:: Over the past few decades, tourism and recreation activities have increased in tropical marine settings, and studies have examined social and ecological impacts of these activities. Some studies have examined social impacts such as encounters, crowding, and encounter norms or standards that individuals use to evaluate encounters with others as...

Does Disability Severity Matter? The Daily Lives of Parent Caregivers of Children with Developmental Disabilities

Creator:: Fenn, Meghann L.
Abstract:: Individuals with disabilities and their parents, even within specific disability diagnoses, have diverse life experiences and trajectories. The current study focuses on parents of individuals with developmental disabilities. Developmental disabilities (DD) are a diverse group of severe chronic conditions evident at birth or acquired during childhood that affect major life...

Cruise ship disturbance to Kittlitz's murrelets (Brachyramphus brevirostris) in Glacier Bay National Park and Preserve, Alaska

Creator:: Marcella, Timothy K.
Abstract:: The Kittlitz's murrelet (Brachyramphus brevirostris), a small pursuit-diving seabird in the family Alcidae, occurs across much of coastal Alaska and parts of the Russian Far East. Glacier Bay National Park, located in Southeast Alaska, is believed to support approximately 37% of the worldwide breeding population of Kittlitz's murrelets during the...

Vegetation response to prescribed fire in mountain big sagebrush ecosystems at Lava Beds National Monument, California

Creator:: Ellsworth, Lisa M.
Abstract:: Anthropogenic land use alterations such as livestock grazing and fire suppression have greatly altered sagebrush grasslands of the Great Basin, facilitating invasion of exotic annuals, increases in woody species, and losses of native species. Much of the current research surrounding wildland and prescribed fire in sagebrush dominated ecosystems has focused...

Parasitoid wasps of Douglas-fir Needle Midge (Contarinia pseudotsugae Condrashoff,1961) larvae in two Christmas tree farms, Willamette Valley, Oregon

Creator:: Voyvot, Saliha
Abstract:: Douglas-fir needle midge (Contarinia pseudotsugae, Diptera: Cecidomyiidae) is a native invasive species in Pacific Northwest Christmas tree farms, seed orchards, and nurseries where Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) is present. Douglas-fir needle midge (DFNM) causes discoloration and galls on the needles, thereby it affects the market value of the Christmas...
