Toxic Pollutants Measured in Surface Water and Fish Collected from the Willamette River Basin by the Oregon Department of Environmental Quality (2008 – 2010)

Creator:: Coyle, Jim, Hamel, Allen, and Johnson, Ben
Abstract:: In 2008 the Oregon Department of Environmental Quality (ODEQ) initiated a program to monitor Oregon’s surface waters and aquatic biota for the presence of pollutants that pose risks to human and/or environmental health. ODEQ’s Toxics Monitoring Program was first implemented in the Willamette River Basin (WRB) between 2008 and 2010....

Interannual variability in the Northern California Current food web structure: Changes in energy flow pathways and the role of forage fish, euphausiids, and jellyfish

Creator:: Ruzicka, James J., Brodeur, Richard D., Emmett, Robert L., Steele, John H., Zamon, Jeannette E., Morgan, Cheryl A., Thomas, Andrew C., and Wainwright, Thomas C.
Abstract:: The Northern California Current (NCC) is a seasonally productive and open ecosystem. It is home to both a diverse endemic community and to seasonally transient species. Productivity and food web structure vary seasonally, interannually, and decadally due to variability in coastal upwelling, climate-scale physical processes, and the migratory species entering...

Shared compatibility of ectomycorrhizae on Pseudotsuga menziesii and Betula papyrifera seedlings grown in mixture in soils from southern British Columbia

Creator:: Simard, Suzanne W., Molina, Randy, Smith, Jane E., Perry, David A., and Jones, Melanie D.
Abstract:: Seedlings of Pseudotsuga menziesii (Mirb.) Franco and Betula papyrifera Marsh. were grown in the greenhouse in monoculture and dual culture in soils collected from a young mixed species plantation in the southern interior of British Columbia. The objectives of the study were (i) to evaluate the ability of P. menziesii...

Perceived Support, Knowledge Tacitness, and Provider Knowledge Sharing

Creator:: Swift, Michele L. and Virick, Meghna
Abstract:: This study provides a direct test of social exchange theory on knowledge sharing from the perspective of the provider by examining the role of both perceived coworker support (PCS) and perceived organizational support (POS) on the extent to which employees share their knowledge with their coworkers. Also examined is the...

Creator:: Ebert, T. A., Hernandez, J. C., and Russell, M. P.
Abstract:: Intraspecific life history attributes of growth, survival, and reproduction can vary in response to changes in the physical environment. These changes can induce a cascading effect across trophic levels. In marine systems, shifts in ocean conditions such as warm and cold phases of ENSO can change primary production in benthic...

Novel bioactive secondary metabolites from the marine cyanobacterium Lyngbya majuscula

Creator:: Wu, Min, 1963-
Abstract:: Marine algae have been recognized as a rich resource of new and unusual organic molecules with diverse biological properties. The current need to develop new antifungal, anticancer, antibiotic and antiviral drugs has led to an intense research effort into the discovery, isolation and structure determination of potential medicinal agents from...

Creator:: Gladics, Amanda J.
Abstract:: Variable ocean conditions can greatly impact lower trophic level prey assemblages in marine ecosystems, with effects propagating up to higher trophic levels. Our goal was to better understand how varying ocean conditions influence diets and niche overlap among a suite of low- to mid trophic level predators. We studied the...

Spatial overlap between forage fishes and the large medusa Chrysaora fuscescens in the northern California Current region

Creator:: Brodeur, Richard D., Barceló, Caren, Robinson, Kelly L., Daly, Elizabeth A., and Ruzicka, James J.
Abstract:: As in many regions of the world, the shelf waters of the western United States have experienced large increases and high interannual variability in jellyfish populations in recent decades. The northern California Current (NCC) is a productive upwelling zone that is home to large populations of medusae, particularly during some...
