Long term albacore (Thunnus alalunga) spatio-temporal association with environmental variability in the Northeastern Pacific

Creator:: Phillips, A. Jason
Abstract:: This study investigated long-term (1961-2008) changes in albacore (Thunnus alalunga) abundance and distribution in relation to local environmental and large-scale climate indices in the Northeastern Pacific using time series and spatial analyses. Prior to the time series analysis, a wavelet analysis was conducted to examine nonrandom patterns of cyclical variability...

Influence of spatial and temporal factors on plants, pollinators and plant-pollinator interactions in montane meadows of the western Cascades Range

Creator:: Pfeiffer, Vera W.
Abstract:: Montane meadows comprise less than 5% of the landscape of the western Cascades of Oregon, but they provide habitat for diverse species of plants and pollinators. Little is known about plant-pollinator network structure at these sites. This study quantified plant-pollinator interactions over the summer of 2011, based on six observations...

Analyzing the present and future Pacific-North American teleconnection using global and regional climate models

Creator:: Allan, Andrea M.
Abstract:: In this thesis I present the results of a comprehensive assessment of the Pacific-North American (PNA) teleconnection pattern in general circulation models (GCMs) and a regional climate model (RCM). The PNA teleconnection pattern is a quasi-stationary wave field over the North Pacific and North America that has long been recognized...

A cooperative effort to track Humboldt squid invasions in Oregon

Creator:: Chesney, Tanya A.
Abstract:: Interannual variability of Humboldt squid (Dosidicus gigas) occurrence in the northern California Current System is largely unknown. In Oregon, the distribution of this versatile predator and what is influencing their range expansion from Mexico is poorly understood due to the recent nature of their "invasion" and a lack of monitoring....

Prey Patch Patterns Predict Habitat Use by Top Marine Predators with Diverse Foraging Strategies

Creator:: Benoit-Bird, Kelly J., Battaile, Brian C., Heppell, Scott A., Hoover, Brian, Irons, David, Jones, Nathan, Kuletz, Kathy J., Nordstrom, Chad A., Paredes, Rosana, Suryan, Robert M., Waluk, Chad M., and Trites, Andrew W.
Abstract:: Spatial coherence between predators and prey has rarely been observed in pelagic marine ecosystems. We used measures of the environment, prey abundance, prey quality, and prey distribution to explain the observed distributions of three co-occurring predator species breeding on islands in the southeastern Bering Sea: black-legged kittiwakes (Rissa tridactyla), thick-billed...

What's that on the beach? Designing a Protocol for the Identification and Reporting of Stranded Marine Fish, Squid, and Turtles Using the Oregon Coast as a Proof-of-Concept

Creator:: Asson, Danielle and Asson, Danielle C.
Abstract:: It is not unusual to see stranded or washed-up marine animals and birds along any coastline. Various networks nationwide exist to report marine mammals and sea birds, yet, we have been unable to find a network in Oregon or nationally to report other stranded marine animals, namely fish, cephalopods, and...

Characterization of ecosystem structure and function recovery within the NOAA MOC-P mitigation basin, Newport, Oregon

Creator:: Lewis, Nate S.
Abstract:: Seagrass ecosystems are considered some of the most productive coastal habitats in the world. One such seagrass within estuaries of the Pacific Northwest, Zostera marina (eelgrass), is recognized to be an ecosystem engineering species that provides many important ecosystem functions and services. In 2010, construction of the National Oceanic and...

Determinants of moth diversity and community in a temperate mountain landscape: vegetation, topography, and seasonality

Creator:: Highland, Steven A., Miller, Jeffrey C., and Jones, Julia A.
Abstract:: Macromoth diversity, abundance, and community structure in the topographically complex HJ Andrews Experimental Forest and LTER site was studied on the west slope of the Cascade Range, Oregon. Data on 493 macromoth species (62,221 individuals) was sampled eight times/year at 20 locations from 2004 to 2008 and examined using multivariate...

Cooperative product development between researchers and commercial fishermen to find applications for ocean condition forecasting technology

Creator:: Duncan, Colin
Abstract:: This is a case study of the cooperative development of an ocean condition forecasting tool by Oregon commercial fishermen, Oregon State University (OSU) scientists, and OSU student software engineers. Ocean condition forecasting models developed by OSU scientists were used to create an online tool to assist decision-making for fishermen. This...

Anomalous porosity preservation and preferential accumulation of gas hydrate in the Andaman accretionary wedge, NGHP-01 site 17A

Creator:: Rose, Kelly K., Johnson, Joel E., Torres, Marta E., Hong, Wei-Li, Giosan, Liviu, Solomon, Evan A., Kastner, Miriam, Cawthern, Thomas, Long, Philip E., and Schaef, H. Todd
Abstract:: In addition to well established properties that control the presence or absence of the hydrate stability zone, such as pressure, temperature, and salinity, additional parameters appear to influence the concentration of gas hydrate in host sediments. The stratigraphic record at Site 17A in the Andaman Sea, eastern Indian Ocean, illustrates...
