Visible Implant Elastomer (VIE) Tags for Marking Small Rainbow Trout

Creator:: Leblanc, C. A. and Noakes, D. L.
Abstract:: Being able to individually follow fish <40 mm in length is a challenge for fish research. In the present study we examined whether the use of visible implant elastomer (VIE) tags is suitable for research on first-feeding rainbow trout Oncorhynchus mykiss raised under laboratory conditions. We assessed the effect of...

Settlement patterns of young-of-the-year rockfish among six Oregon estuaries experiencing different levels of human development

Creator:: Dauble, Alison D., Heppell, Scott A., and Johansson, Mattias L.
Abstract:: In the US Pacific Northwest, rockfishes Sebastes spp. have recently become a focus for increased management efforts; several species are currently managed under extreme conservation measures due to low population levels and intense fishing pressure. Rockfish recruitment is extremely variable, and a better understanding of the factors influencing recruitment and...

Effects of water withdrawals on macroinvertebrate emergence: Unexpected results for three holometabolous species

Creator:: Brown, P. D., Wooster, D., Johnson, S. L., and DeBano, S. J.
Abstract:: Small, low-head diversion dams are capable of withdrawing much of the flow of a river, often resulting in elevated water temperatures. Accelerated growth and development of aquatic invertebrates has been demonstrated in warmer temperatures, suggesting that the timing of insect emergence and adult body size may be significantly altered by...

Effects of juvenile steelhead on juvenile chinook salmon behavior and physiology

Creator:: Kelsey, D. A., Schreck, Carl B., Congleton, J. L., and Davis, L. E.
Abstract:: Experiments were designed to determine whether and how steelhead Oncorhynchus mykiss affect chinook salmon O. tshawytscha when the two species are confined together. In a behavioral experiment, we observed groups of juvenile chinook salmon and steelhead together and groups of chinook salmon alone to determine whether the steelhead were aggressive...

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....

Intra‐ and inter‐annual variation in gray whale body condition on a foraging ground

Creator:: Soledade Lemos, Leila, Burnett, Jonathan D., Chandler, Todd E., Sumich, James L., and Torres, Leigh G.
Abstract:: Baleen whales store energy gained on foraging grounds to support reproduction and other metabolic needs while fasting for long periods during migration. Whale body condition can be used to monitor foraging success, and thus better understand and anticipate individual‐ and population‐level trends in reproduction and survival. We assessed the body...

Evidence for regional‐scale controls on eelgrass (Zostera marina) and mesograzer community structure in upwelling‐influenced estuaries

Creator:: Hayduk, Jennifer L., Hacker, Sally D., Henderson, Jeremy S., and Tomas, Fiona
Abstract:: Community structure and function in ecosystems are dependent on top‐down and bottom‐up factors, which vary across local, regional, and temporal scales. In estuaries of the U.S. Pacific Northwest coast, eelgrass (Zostera marina) ecosystems are exposed to latitudinally varying oceanographic inputs in the form of ocean upwelling. Previous research suggests that...

Environmental stewardship practices of veterinary professionals and educators related to use and disposal of pharmaceuticals and personal care products

Creator:: Stone, David, Lam, Jennifer, Conway, Flaxen D. L., and Chan, Samuel S.
Abstract:: OBJECTIVE To document the environmental stewardship practices (decisions and actions regarding use and disposal) of pet and human pharmaceuticals and personal care products (PPCPs) among pet-owning veterinary-care professionals (practicing veterinarians, veterinary students, and veterinary technicians and trainees) and environmental educators. DESIGN Internet-based cross-sectional survey. SAMPLE 191 pet owners (103 veterinary-care...

Colonization and extinction in dynamic habitats: an occupancy approach for a Great Plains stream fish assemblage

Creator:: Falke, Jeffrey A., Bailey, Larissa L., Fausch, Kurt D., and Bestgen, Kevin R.
Abstract:: Despite the importance of habitat in determining species distribution and persistence, habitat dynamics are rarely modeled in studies of metapopulations. We used an integrated habitat-occupancy model to simultaneously quantify habitat change, site fidelity, and local colonization and extinction rates for larvae of a suite of Great Plains stream fishes in...

Macondo-1 well oil-derived polycyclic aromatic hydrocarbons in mesozooplankton from the northern Gulf of Mexico

Creator:: Mitra, Siddhartha, Kimmel, David G., Snyder, Jessica, Scalise, Kimberly, McGlaughon, Benjamin D., Roman, Michael R., Jahn, Ginger L., Pierson, James J., Brandt, Stephen B., Montoya, Joseph P., Rosenbauer, Robert J., Lorenson, Thomas D., Wong, Florence L., and Campbell, Pamela L.
Abstract:: Mesozooplankton (>200 μm) collected in August and September of 2010 from the northern Gulf of Mexico show evidence of exposure to polycyclic aromatic hydrocarbons (PAHs). Multivariate statistical analysis revealed that distributions of PAHs extracted from mesozooplankton were related to the oil released from the ruptured British Petroleum Macondo-1 (M-1) well...
