Using Spatial Resampling to Assess Redd Count Survey Length Requirements for Pacific Lamprey

Creator:: Mayfield, M. P., Schultz, L. D., Wyss, L. A., Colvin, M. E., and Schreck, C. B.
Abstract:: Pacific Lamprey Entosphenus tridentatus has declined across its range along the West Coast of North America, and an understanding of all life history phases is needed to address population recovery. Spawning surveys (redd counts) are common tools currently used to monitor returning adult salmonids, but such methodologies are in their...

Life Histories, Demography, and Distribution of a Fluvial Bull Trout Population

Creator:: Howell, Philip J., Colvin, Michael E., Sankovich, Paul M., Buchanan, David V., and Hemmingsen, Alan R.
Abstract:: To describe the life histories and demography of a fluvial population of Bull Trout Salvelinus confluentus, we PIT-tagged and radio-tagged Bull Trout captured in Mill Creek, a tributary of the Walla Walla River (Washington–Oregon), during 1998–2009. Adult abundance declined 63% during 2006–2010, driven primarily by a 10-fold reduction in subadult-to-adult...

Innate and adaptive immune responses in migrating spring-run adult chinook salmon, Oncorhynchus tshawytscha

Creator:: Dolan, Brian P., Fisher, Kathleen M., Colvin, Michael E., Benda, Susan E., Peterson, James T., Kent, Michael L., and Schreck, Carl B.
Abstract:: Adult Chinook salmon (Oncorhynchus tshawytscha) migrate from salt water to freshwater streams to spawn. Immune responses in migrating adult salmon are thought to diminish in the run up to spawning, though the exact mechanisms for diminished immune responses remain unknown. Here we examine both adaptive and innate immune responses as...

Regional Differences in Taste Responsiveness: Effect of Stimulus and Tasting Mode

Creator:: Colvin, Julie L., Pullicin, Alexa J., and Lim, Juyun
Abstract:: Previous studies have shown that there are differences in taste responses between various regions of the tongue. Most of those studies used a controlled "passive" tasting mode due to the nature of investigation. However, food is rarely tasted in a passive manner. In addition, recent studies have suggested that humans...

Phytochemical profiles and antioxidant activity of some grape accessions (Vitis spp.) native to Eastern Anatolia of Turkey

Creator:: Eyduran, Sadiye Peral, Akin, Meleksen, Ercisli, Sezai, and Eyduran, Ecevit
Abstract:: Phytochemical profiles and antioxidant activity of four historical grape accessions (‘Kuzu Kuyrugu’, ‘Miskali’, ‘Erkek Miskali’, and ‘Kirmizi Kismis’) grown in Igdir province located in Eastern Anatolia Region of Turkey were examined. The amount of vitamin C, organic acids (citric acid, tartaric acid, malic acid, succinic acid and fumaric acid), sugars...

Tolerance and Efficacy of Emamectin Benzoate and Ivermectin for the Treatment of Pseudocapillaria tomentosa in Laboratory Zebrafish (Danio rerio)

Creator:: Collymore, Chereen, Watral, Virginia, White, Julie R., Colvin, Michael E., Rasmussen, Skye, Tolwani, Ravi J., and Kent, Michael L.
Abstract:: Tolerance of adult zebrafish and efficacy of emamectin benzoate and ivermectin in eliminating Pseudocapillaria tomentosa infection were evaluated. In the tolerance study, behavioral changes, fecundity, histopathology, and mortality were evaluated for in-feed administration of emamectin (0.05, 0.10, and 0.25 mg/kg) and ivermectin (0.05 and 0.10 mg/kg). All doses of emamectin...

Sediment depths determined by comparison of grape and logging denisty data during Leg 138

Creator:: Mix, Alan C., Harris, Sara E., Hagelberg, T. K., Pisias, Nicklas G., and Shackleton, N. J.
Abstract:: Establishing true depths of recovered sediments is critical to determining sedimentation rates for high-resolution paleoclimatic studies. We have corrected the composite depth scale, which accounts for the entire continuous sedimentary sequence, so that sediment depths are consistent with logging depths, or "true" depths. We accomplished this by taking advantage of...

Headwater Streams and Wetlands are Critical for Sustaining Fish, Fisheries, and Ecosystem Services

Abstract:: Headwater streams and wetlands are integral components of watersheds that are critical for biodiversity, fisheries, ecosystem functions, natural resource-based economies, and human society and culture. These and other ecosystem services provided by intact and clean headwater streams and wetlands are critical for a sustainable future. Loss of legal protections for...

Occupancy Modeling for Improved Accuracy and Understanding of Pathogen Prevalence and Dynamics

Creator:: Colvin, Michael E., Peterson, James T., Kent, Michael L., and Schreck, Carl B.
Abstract:: Most pathogen detection tests are imperfect, with a sensitivity < 100%, thereby resulting in the potential for a false negative, where a pathogen is present but not detected. False negatives in a sample inflate the number of non-detections, negatively biasing estimates of pathogen prevalence. Histological examination of tissues as a...

Data report : trace element, Sr isotope, and Ge/SI composition of fluid and sediments in ridge-flank low-temperature hydrothermal environments

Creator:: Hulme, Samuel M., Wheat, C. Geoffrey, Coggon, Rosalind M., and McManus, James
Abstract:: The data presented in this report demonstrate significant improvements in the ability to constrain trace element and Sr isotopic concentrations in sediments overlying ridge-flank hydrothermal systems. Improved sampling methods orchestrated by the Integrated Ocean Drilling Program (i.e., advanced piston coring and anoxic sample processing) enabled the collection of reactive pore...
