A Multi-Year Longitudinal Study of Water Quality Parameters in Four Salmon-Bearing and Recreational Streams on Mount Hood, Oregon

Creator:: Wasowski, Ronald, Alexander, David, Kolmes, Steven, Banet, Nathan, Card, Amy, Haines, Morgan, Kolmes, Elijah, Northcutt, Kelly, Roemer, Derek, and Webber, Sarah
Abstract:: Four streams-Clear Fork, Lost Creek, Camp Creek and Still Creek-in northwestern Oregon's Sandy River Basin were monitored for temperature, dissolved oxygen levels, and fecal bacterial concentrations in a multi-year analysis examining stream health for recreational users and anchor habitat for Pacific Salmon. Temperatures were recorded using micro -T temperature loggers...

A Numerical Examination of ¹⁴CO₂ Chamber Methodologies for Sampling at the Soil Surface

Creator:: Egan, Jocelyn, Nickerson, Nick, Phillips, Claire, and Risk, Dave
Abstract:: Radiocarbon is an exceptionally useful tool for studying soil-respired CO₂, providing information about soil carbon turnover rates, depths of production, and the biological sources of production through partitioning. Unfortunately, little work has been done to thoroughly investigate the possibility of inherent biases present in current measurement techniques, like those present...

A regional real-time forecast of marine boundary layers during VOCALS-REx

Creator:: Wang, S., O'Neill, L. W., Jiang, Q., de Szoeke, Simon P., Hong, X., Jin, H., Thompson, W. T., and Zheng, X.
Abstract:: This paper presents an evaluation and validation of the Naval Research Laboratory's COAMPS® real-time forecasts during the VOCALS-REx over the area off the west coast of Chile/Peru in the Southeast Pacific during October and November 2008. The analyses focus on the marine boundary layer (MBL) structure. These forecasts are compared...

AI, Robot: A Rhetorical Analysis of Jeopardy! Matches Featuring IBM’s Artificial Intelligence

Creator:: Steele, Evan T.
Abstract:: The relationship between the public and new technologies has historically been a tumultuous one, with public perceptions ranging from excited rapid adoption to standoffish pessimism. In 2011, IBM tried to use competition as a means of showcasing a new technology to the public. This thesis is a work of rhetorical...

An Evaluation of Putative Sympatric Speciation within Limnanthes (Limnanthaceae)

Creator:: Meyers, Stephen C., Liston, Aaron, and Meinke, Robert
Abstract:: Limnanthes floccosa ssp. floccosa and L. floccosa ssp. grandiflora are two of five subspecies within Limnanthes floccosa endemic to vernal pools in southern Oregon and northern California. Three seasons of monitoring natural populations have quantified that L. floccosa ssp. grandiflora is always found growing sympatrically with L. floccosa ssp. floccosa...

Assessing the design and power of capture-recapture studies to estimate demographic parameters for the Endangered Oceania humpback whale population

Creator:: Carroll, E. L., Brooks, L., Baker, C. S., Burns, D., Garrigue, C., Hauser, N., Jackson, J. A., Poole, M. M., and Fewster, R. M.
Abstract:: Capture-recapture studies offer a powerful tool to assess abundance, survival and population rate of change (λ). A previous capture-recapture study, based on DNA profiles, estimated that the IUCN-listed Endangered Oceania population of humpback whales had a superpopulation size of 4329 whales (95% confidence limits, CL: 3345, 5315) and λ =...

Circumpolar Diversity and Geographic Differentiation of mtDNA in the Critically Endangered Antarctic Blue Whale (Balaenoptera musculus intermedia)

Creator:: Sremba, Angela L., Hancock-Hanser, Brittany, Branch, Trevor A., LeDuc, Rick L., and Baker, C. Scott
Abstract:: The Antarctic blue whale (Balaenoptera musculus intermedia) was hunted to near extinction between 1904 and 1972, declining from an estimated initial abundance of more than 250,000 to fewer than 400. Here, we describe mtDNA control region diversity and geographic differentiation in the surviving population of the Antarctic blue whale, using...

Comparative Composition, Diversity and Trophic Ecology of Sediment Macrofauna at Vents, Seeps and Organic Falls

Creator:: Bernardino, Angelo F., Levin, Lisa A., Thurber, Andrew R., and Smith, Craig R.
Abstract:: Sediments associated with hydrothermal venting, methane seepage and large organic falls such as whale, wood and plant detritus create deep-sea networks of soft-sediment habitats fueled, at least in part, by the oxidation of reduced chemicals. Biological studies at deep-sea vents, seeps and organic falls have looked at macrofaunal taxa, but...

Critically low abundance and limits to human-related mortality for the Maui's dolphin

Creator:: Hamner, Rebecca M., Wade, Paul, Oremus, Marc, Stanley, Martin, Brown, Phillip, Constantine, Rochelle, and Baker, C. Scott
Abstract:: The New Zealand endemic Maui’s dolphin Cephalorhynchus hectori maui is characterized by several life history traits thought to be important predictors of extinction risk in marine mammals, including a slow rate of reproduction, small geographic range, small group size, and coastal distribution. We continued the genetic monitoring of the remnant...

Development and Infectious Disease in Hosts with Complex Life Cycles

Creator:: Searle, Catherine L., Xie, Gisselle Yang, and Blaustein, Andrew R.
Abstract:: Metamorphosis is often characterized by profound changes in morphology and physiology that can affect the dynamics of species interactions. For example, the interaction between a pathogen and its host may differ depending on the life stage of the host or pathogen. One pathogen that infects hosts with complex life cycles...
