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

Creator:: Colvin, Susan A. R., Sullivan, S. Mazeika P., Shirey, Patrick D., Colvin, Randall W., Winemiller, Kirk O., Hughes, Robert M., Fausch, Kurt D., Infante, Dana M., Olden, Julian D., Bestgen, Kevin R., Danehy, Robert J., and Eby, Lisa
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...

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...

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...

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...

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...

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...

Detailed volcanostratigraphy of an accreted seamount: Implications for intraplate seamount formation

Creator:: Schnur, Susan R. and Gilbert, Lisa A.
Abstract:: Seamounts are a ubiquitous feature of the seafloor but relatively little is known about their internal structure. A seamount preserved in the Franciscan mélange of California suggests a sequence of formation common to all seamounts. Field mapping, geophysical measurements, and geochemical analyses are combined to interpret three stages of seamount...

Deforestation Trends of Tropical Dry Forests in Central Brazil

Creator:: Bianchi, Carlos A. and Haig, Susan M.
Abstract:: Tropical dry forests are the most threatened forest type in the world yet a paucity of research about them stymies development of appropriate conservation actions. The Paran~a River Basin has the most significant dry forest formations in the Cerrado biome of central Brazil and is threatened by intense land conversion...

Food deprivation affects vertical distribution and activity of a marine fish in a thermal gradient: potential energy-conserving mechanisms

Creator:: Sogard, Susan M. and Olla, Bori L.
Abstract:: The effects of reduced food availability on the behavior of juvenile walleye pollock Theragra chalcogramma were examined in laboratory experiments designed to test for potential energy-conserving responses. Groups of juvenile fish were held on 1 of 6 ration treatments ranging from ad libitum to near starvation, and then vertical distribution...
