Characterization of the physiological stress response in lingcod

Creator:: Milston, Ruth H., Davis, Michael W., Parker, Steven J., Olla, Bori L., Clements, Shaun, and Schreck, Carl B.
Abstract:: The goal of this study was to describe the duration and magnitude of the physiological stress response in lingcod Ophiodon elongatus after exposure to brief handling and sublethal air stressors. The response to these stressors was determined during a 24‐h recovery period by measuring concentrations of plasma cortisol, lactate, glucose,...

Abundance, movements, and feeding habits of harbor seals, Phoca vitulina, at Netarts and Tillamook Bays, Oregon

Creator:: Brown, Robin F. and Mate, Bruce R.
Abstract:: Patterns of seasonal abundance of harbor seals at Netarts and Tillamook Bays, Oregon, were documented by recording numbers of seals hauling out on tidally exposed sand flats in both bays. Harbor seal abundance at Tillamook Bay peaked during pupping (May-June) and molting (August) periods, while peak abundance at Netarts Bay...

Spatial and Temporal Variability of Macroinvertebrates in Spawning and Non-Spawning Habitats during a Salmon Run in Southeast Alaska

Creator:: Campbell, Emily Y., Merritt, Richard W., Cummins, Kenneth W., and Benbow, M. Eric
Abstract:: Spawning salmon create patches of disturbance through redd digging which can reduce macroinvertebrate abundance and biomass in spawning habitat. We asked whether displaced invertebrates use non-spawning habitats as refugia in streams. Our study explored how the spatial and temporal distribution of macroinvertebrates changed during a pink salmon (Oncorhynchus gorbuscha) spawning...

When is bigger better? Early marine residence of middle and upper Columbia River spring Chinook salmon

Creator:: Tomaro, Londi M., Teel, David J., Peterson, William T., and Miller, Jessica A.
Abstract:: Early ocean residence is considered a critical period for juvenile salmon although specific survival mechanisms are often unidentified and may vary by species or life stage. Columbia River spring-run Chinook salmon Oncorhynchus tshawytscha abundance has declined dramatically since the early 1900s. To elucidate mechanisms of early marine survival, we tested...

Meta-analysis of avian and small-mammal response to fire severity and fire surrogate treatments in U.S. fire-prone forests

Creator:: Fontaine, Joseph B. and Kennedy, Patricia L.
Abstract:: Management in fire-prone ecosystems relies widely upon application of prescribed fire and/or fire surrogate (e.g., forest thinning) treatments to maintain biodiversity and ecosystem function. Recently, published literature examining wildlife response to fire and fire management has increased rapidly. However, none of this literature has been synthesized quantitatively, precluding assessment of...

Translocating Adult Pacific Lamprey within the Columbia River Basin: State of the Science

Creator:: Ward, David L., Clemens, Benjamin J., Clugston, David, Jackson, Aaron D., Moser, Mary L., Peery, Chris, and Statler, David P.
Abstract:: The Pacific lamprey (Entosphenus tridentatus) is in decline in the Columbia River Basin, and translocating adult lamprey to bypass difficult migration corridors has been implemented since 2000. We describe and report results from two current translocation programs, provide context for use of translocation, and discuss potential benefits, risks, and uncertainties....

Surprises and Insights from Long-Term Aquatic Data Sets and Experiments

Creator:: Dodds, Walter K., Robinson, Christopher T., Gaiser, Evelyn E., Hansen, Gretchen J. A., Powell, Heather, Smith, Joseph M., Morse, Nathaniel B., Johnson, Sherri L., Gregory, Stanley V., Bell, Tisza, Kratz, Timothy K., and McDowell, William H.
Abstract:: Long-term research on freshwater ecosystems provides insights that can be difficult to obtain from other approaches. Widespread monitoring of ecologically relevant water-quality parameters spanning decades can facilitate important tests of ecological principles. Unique long-term data sets and analytical tools are increasingly available, allowing for powerful and synthetic analyses across sites....

Can catch share fisheries better track management targets?

Creator:: Melnychuk, Michael C., Essington, Timothy E., Branch, Trevor A., Heppell, Selina S., Jensen, Olaf P., Link, Jason S., Martell, Steven J. D., Parma, Ana M., Pope, John G., and Smith, Anthony D. M.
Abstract:: Fisheries management based on catch shares – divisions of annual fleet-wide quotas among individuals or groups – has been strongly supported for their economic benefits, but biological consequences have not been rigorously quantified. We used a global meta-analysis of 345 stocks to assess whether fisheries under catch shares were more...

Individual condition and stream temperature influence early maturation of rainbow and steelhead trout, Oncorhynchus mykiss

Creator:: McMillan, John R., Dunham, Jason B., Reeves, Gordon H., Mills, Justin S., and Jordan, Chris E.
Abstract:: Alternative male phenotypes in salmonine fishes arise from individuals that mature as larger and older anadromous marine-migrants or as smaller and younger freshwater residents. To better understand the processes influencing the expression of these phenotypes we examined the influences of growth in length (fork length) and whole body lipid content...

Harmful algal blooms along the North American west coast region: History, trends, causes, and impacts

Creator:: Lewitus, Alan J., Horner, Rita A., Caron, David A., Garcia-Mendoza, Ernesto, Hickey, Barbara M., Hunter, Matthew, Huppert, Daniel D., Kudela, Raphael M., Langlois, Gregg W., Largier, John L., Lessard, Evelyn J., RaLonde, Raymond, Rensel, J. E. Jack, Strutton, Peter G., Trainer, Vera L., and Tweddle, Jacqueline F.
Abstract:: Along the Pacific coast of North America, from Alaska to Mexico, harmful algal blooms (HABs) have caused losses to natural resources and coastal economies, and have resulted in human sicknesses and deaths for decades. Recent reports indicate a possible increase in their prevalence and impacts of these events on living...
