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...

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...

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...

Phylotastic! Making tree-of-life knowledge accessible, reusable and convenient

Creator:: Stoltzfus, Arlin, Lapp, Hilmar, Matasci, Naim, Deus, Helena, Sidlauskas, Brian, Zmasek, Christian M., Vaidya, Gaurav, Pontelli, Enrico, Cranston, Karen, Vos, Rutger, Webb, Campbell O, Harmon, Luke J., Pirrung, Megan, O'Meara, Brian, Pennell, Matthew W., Mirarab, Siavash, Rosenberg, Michael S., Balhoff, James P., Bik, Holly M., Heath, Tracy A., Midford, Peter E., Brown, Joseph W., McTavish, Emily Jane, Sukumaran, Jeet, Westneat, Mark, Alfaro, Michael E., Steele, Aaron, and Jordan, Greg
Abstract:: Background: Scientists rarely reuse expert knowledge of phylogeny, in spite of years of effort to assemble a great “Tree of Life” (ToL). A notable exception involves the use of Phylomatic, which provides tools to generate custom phylogenies from a large, pre-computed, expert phylogeny of plant taxa. This suggests great potential...

Impact of land use patterns and agricultural practices on water quality in the Calapooia River Basin of western Oregon

Creator:: Mueller-Warrant, G. W., Griffith, S. M., Whittaker, G. W., Banowetz, G. M., Pfender, W. F., Garcia, T. S., and Giannico, G. R.
Abstract:: Agricultural practices, including tillage, fertilization, and residue management, can affect surface runoff, soil erosion, and nutrient cycling. These processes, in turn, may adversely affect (1) quality of aquatic resources as habitat for amphibians, fish, and invertebrates, (2) costs of treating surface and ground water to meet drinking water standards, and...

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...

Survival and Home-range Size of Northern Spotted Owls in Southwestern Oregon

Creator:: Schilling, Jason W., Dugger, Katie M., and Anthony, Robert G.
Abstract:: In the Klamath province of southwestern Oregon, Northern Spotted Owls (Strix occidentalis caurina) occur in complex, productive forests that historically supported frequent fires of variable severity. However, little is known about the relationships between Spotted Owl survival and home-range size and the characteristics of fire-prone, mixed-conifer forests of the Klamath...

A new species of western Atlantic lizardfish (Teleostei: Synodontidae: Synodus) and resurrection of Synodus bondi Fowler, 1939, as a valid species from the Caribbean with redescriptions of S. bondi, S. foetens (Linnaeus, 1766), and S. intermedius (Agassiz, 1829)

Creator:: Frable, Benjamin W., Baldwin, Carole C., Luther, Brendan M., and Weigt, Lee A.
Abstract:: Western Atlantic synodontid species were studied as part of an ongoing effort to reanalyze Caribbean shorefish diversity. A neighbor-joining tree constructed from cytochrome c oxidase I (COI) data revealed 2 highly divergent genetic lineages within both Synodus intermedius (Agassiz, 1829) (Sand Diver) and S. foetens (Linnaeus, 1766) (Inshore Lizardfish).

Characterizing coal and mineral mines as a regional source of stress to stream fish assemblages

Creator:: Daniel, Wesley M., Infante, Dana M., Hughes, Robert M., Tsang, Yin-Phan, Esselman, Peter C., Wieferich, Daniel, Herreman, Kyle, Cooper, Arthur R., Wang, Lizhu, and Taylor, William W.
Abstract:: Mining impacts on stream systems have historically been studied over small spatial scales, yet investigations over large areas may be useful for characterizing mining as a regional source of stress to stream fishes. The associations between co-occurring stream fish assemblages and densities of various “classes” of mining occurring in the...

Body Size and Growth Rate Influence Emigration Timing of Oncorhynchus mykiss

Creator:: Tattam, Ian A., Ruzycki, James R., Li, Hiram W., and Giannico, Guillermo R.
Abstract:: Juvenile Oncorhynchus mykiss migrate extensively in freshwater during fall. We used individual tagging to study the spatial origin, influences, and outcomes of fall migration on fish that emigrated from summer rearing tributaries during fall (early-emigrants) and those that did not (late-emigrants) in the South Fork John Day River, Oregon. Fall...
