Decomposition and nitrogen dynamics of ¹⁵N‑labeled leaf, root, and twig litter in temperate coniferous forests

Creator:: van Huysen, Tiff L., Harmon, Mark E., Perakis, Steven S., and Chen, Hua
Abstract:: Litter nutrient dynamics contribute significantly to biogeochemical cycling in forest ecosystems. We examined how site environment and initial substrate quality influence decomposition and nitrogen (N) dynamics of multiple litter types. A 2.5-year decomposition study was installed in the Oregon Coast Range and West Cascades using ¹⁵N-labeled litter from Acer macrophyllum,...

Investigating the impact of chronic atrazine exposure on sexual development in zebrafish

Creator:: Corvi, Margaret M., Stanley, Kerri A., Peterson, Tracy S., Kent, Michael L., Feist, Stephen W., La Du, Jane K., Volz, David C., Hosmer, Alan J., and Tanguay, Robert L.
Abstract:: Atrazine (ATZ) is a selective triazine herbicide used primarily for pre-emergent weed control in corn, sorghum and sugar cane production. It is one of the most widely used herbicides in North America. Some research published over the last decade suggests that chronic exposure to environmentally relevant ATZ concentrations can adversely...

Nighttime foraging by deep diving echolocating odontocetes off the Hawaiian islands of Kauai and Ni’ihau as determined by passive acoustic monitors

Creator:: Au, Whitlow W. L., Giorli, Giacomo, Chen, Jessica, Copeland, Adrienne, Lammers, Marc, Richlen, Michael, Jarvis, Susan, Morrissey, Ronald, Moretti, David, and Klinck, Holger
Abstract:: Remote autonomous ecological acoustic recorders (EARs) were deployed in deep waters at five locations around the island of Kauai and one in waters off Ni'ihau in the main Hawaiian island chain. The EARs were moored to the bottom at depths between 400 and 800 m. The data acquisition sampling rate...

Minimizing the Pain and Probability of Rejection: Evidence for Relational Distancing and Proximity Seeking Within Face-to-Face Interactions

Creator:: Sommer, Kristin L. and Bernieri, Frank
Abstract:: Prior research has revealed evidence for both proximity seeking and relational distancing following interpersonal rejection (Williams, 2007). The present study explored evidence for both processes in the context of face-to-face interactions. Participants were accepted or rejected by one person then asked to interact with a new relationship partner for the...

Capture-Related Stressors Impair Immune System Function in Sablefish

Creator:: Lupes, Sarah C., Davis, Michael W., Olla, Bori L., and Schreck, Carl B.
Abstract:: The sablefish Anoplopoma fimbria is a valuable North Pacific Ocean species that, when not targeted in various commercial fisheries, is often a part of discarded bycatch. Predictions of the survival of discarded fish are dependent on understanding how a fish responds to stressful conditions. Our objective was to describe the...

Mortality of Lingcod Towed in a Net as Related to Fish Length, Seawater Temperature, and Air Exposure: A Laboratory Bycatch Study

Creator:: Davis, Michael W. and Olla, Bori L.
Abstract:: The mortality of discarded bycatch is a critical problem in the management of fisheries worldwide. Little is known about the key principles involved in the mortality of discarded bycatch. These principles are best elaborated under controlled conditions in the laboratory where the actions and interactions of stressors found in fishing...

Cumulative Effects of Natural and Anthropogenic Stress on Immune Function and Disease Resistance in Juvenile Chinook Salmon

Creator:: Jacobson, Kym C., Arkoosh, Mary R., Kagley, Anna N., Clemons, Ethan R., Collier, Tracy K., and Casillas, Edmundo
Abstract:: Previous studies have shown that juvenile chinook salmon Oncorhynchus tshawytscha exposed in the field or the laboratory to polychlorinated biphenyls (PCBs), an anthropogenic stressor, are immunosuppressed. It is not known whether simultaneous exposure to natural stressors can increase this immunosuppression. To examine the effects of natural and anthropogenic stressors on...

Alder Canopy Dieback and Damage in Western Oregon Riparian Ecosystems

Creator:: Sims, Laura, Goheen, Ellen, Kanaskie, Alan, and Hansen, Everett
Abstract:: We gathered baseline data to assess alder tree damage in western Oregon riparian ecosystems. We sought to determine if Phytophthora-type cankers found in Europe or the pathogen Phytophthora alni subsp. alni, which represent a major threat to alder forests in the Pacific Northwest, were present in the study area. Damage...

Invaded range of the blackberry pathogen Phragmidium violaceum in the Pacific Northwest of the USA and the search for its provenance

Creator:: Morin, Louise, Gomez, Don R., Evans, Katherine J., Neill, Tara M., Mahaffee, Walt F., and Linde, Celeste C.
Abstract:: Field surveys in 2006 confirmed that the exotic rust fungus Phragmidium violaceum was widespread on Rubus armeniacus and Rubus laciniatus in the Pacific Northwest of the USA. The origin and dispersal pattern of this obligate biotrophic pathogen in the USA were investigated by comparing the genetic diversity and structure of...
