Differential gene expression between fall- and spring-run Chinook salmon assessed by long serial analysis of gene expression

Creator:: Bernier, Jeremiah C., Birkeland, Shanda R., Cipriano, Michael J., McArthur, Andrew G., and Banks, Michael A.
Abstract:: Of all Pacific salmonids, Chinook salmon Oncorhynchus tshawytscha display the greatest variability in return times to freshwater. The molecular mechanisms of these differential return times have not been well described. Current methods, such as long serial analysis of gene expression (LongSAGE) and microarrays, allow gene expression to be analyzed for...

Buoyancy regulation by hatchery and wild coho salmon during the transition from freshwater to marine environments

Creator:: Weitkamp, Laurie A.
Abstract:: One aspect of diadromy that has received little attention is buoyancy regulation in fish moving between freshwater and marine environments. Because of density differences between the two water types, fish must alter their whole-fish density (WFD) or they will become positively (float) or negatively (sink) buoyant as they change environments....

Effects of Stage 0 treatment on spring Chinook juveniles within South Fork McKenzie River in Oregon

Creator:: Hahn, Aleah
Abstract:: Low-tech habitat restoration techniques, including Stage 0 treatments, are increasingly applied but often lack robust evaluation of their effects. In 2018, one kilometer of the South Fork McKenzie (SFMK) River, OR was modified to the Stage 0 condition for the benefit of ESA-listed Chinook by raising the incised channel to...

Creator:: Falke, Jeffrey A., Flitcroft, Rebecca L., Dunham, Jason B., McNyset, Kristina M., Hessburg, Paul F., and Reeves, Gordon H.
Abstract:: Linked atmospheric and wildfire changes will complicate future management of native coldwater fishes in fire-prone landscapes, and new approaches to management that incorporate uncertainty are needed to address this challenge. We used a Bayesian network (BN) approach to evaluate population vulnerability of bull trout (Salvelinus confluentus) in the Wenatchee River...

Creator:: Batchelder, Harold P., Daly, Kendra L., Davis, Cabell S., Ji, Rubao, Ohman, Mark D., Peterson, William T., and Runge, Jeffrey A.
Abstract:: The 20-year US GLOBEC (Global Ocean Ecosystem Dynamics) program examined zooplankton populations and their predators in four coastal marine ecosystems. Program scientists learned that environmental controls on zooplankton vital rates, especially the timing and magnitude of reproduction, growth, life-cycle progression, and mortality, determine species population dynamics, seasonal and spatial distributions,...

Hepatic heat shock protein 70 and plasma cortisol levels in rainbow trout after tagging with a passive integrated transponder

Creator:: Feldhaus, Joseph W., Heppell, Scott A., Mesa, Matthew G., and Li, Hiram W.
Abstract:: This study examined the potentially stressful effects of tagging juvenile rainbow trout Oncorhynchus mykiss with passive integrated transponder (PIT) tags by measuring short-term (<120-h) changes in plasma concentrations of cortisol and hepatic heat shock protein 70 (hsp70). In a laboratory experiment, plasma cortisol levels were measured in fish before they...

Lamprey of the Goose Lake Basin: A Multi-Scale Habitat & Distribution Analysis

Creator:: Dickey, Jacob C.
Abstract:: Two ecologically important lamprey species found in the endorheic Goose Lake Basin face conservation threats; however, relatively little is known about their habitat needs or spatial distribution. Lamprey and their habitat are often found to be patchy; to evaluate these relationships for the lamprey in this basin, I utilized a...

Position estimation

Creator:: McKenney, Paul E.
Abstract:: Acoustic position estimation is used where high accuracy navigation is required over a small area, such as for searching or for collecting gravitational or geomagnetic data. In this position estimation method, a surface ship or submersible periodically sends out a high-frequency acoustic 'ping' at a prearranged frequency. This ping is...

Riparian defoliation by the invasive green alder sawfly influences terrestrial prey subsidies to salmon streams

Creator:: Roon, David A., Wipfli, Mark S., and Kruse, James J.
Abstract:: Invasive species in riparian forests are unique as their effects can transcend ecosystem boundaries via stream-riparian linkages. The green alder sawfly (Monsoma pulveratum) is an invasive wasp whose larvae are defoliating riparian thin-leaf alder (Alnus tenuifolia) stands across southcentral Alaska. To test the hypothesis that riparian defoliation by this invasive...

Anadromy and residency in steelhead and rainbow trout (Oncorhynchus mykiss): a review of the processes and patterns

Creator:: Kendall, Neala W., McMillan, John R., Sloat, Matthew R., Buehrens, Thomas W., Quinn, Thomas P., Pess, George R., Kuzishchin, Kirill V., McClure, Michelle M., and Zabela, Richard W.
Abstract:: Oncorhynchus mykiss form partially migratory populations with anadromous fish that undergo marine migrations and residents that complete their life cycle in fresh water. Many populations’ anadromous components are threatened or endangered, prompting interest in understanding ecological and evolutionary processes underlying anadromy and residency. In this paper, we synthesize information to...
