Statistical analysis on otolith data of anadromous fishes

Creator:: Gao, Yongwen, Conrad, Robert, Bean, David, and Noakes, David L. G.
Abstract:: Stable oxygen and carbon isotope δ[superscript 18]O and δ[superscript 13]C analyses of otoliths are becoming increasingly common in fisheries science and management. However, little is known about the statistical properties of isotopic data and few attempts have been made to explore appropriate statistical methods that could be used for otolith...

Creator:: Putman, Nathan F., Meinke, Amanda M., and Noakes, David L. G.
Abstract:: We used simulated magnetic displacements to test orientation preferences of juvenile steelhead trout (Oncorhynchus mykiss) exposed to magnetic fields existing at the northernmost and southernmost boundaries of their oceanic range. Fish reared in natural magnetic conditions distinguished between these two fields by orienting in opposite directions, with headings that would...

Instream cover and shade mediate avian predation on trout in semi-natural streams

Creator:: Penaluna, Brooke E., Dunham, Jason B., and Noakes, David L. G.
Abstract:: Piscivory by birds can be significant, particularly on fish in small streams and during seasonal low flow when available cover from predators can be limited. Yet, how varying amounts of cover may change the extent of predation mortality from avian predators on fish is not clear. We evaluated size-selective survival...

Developmental rate: A unifying mechanism for sympatric divergence in postglacial fishes?

Creator:: Mcphee, Megan V., Noakes, David L. G., and Allendorf, Fred W.
Abstract:: Morphologically divergent ecotypes arise in fish populations on postglacial time scales, and resource polymorphisms are often invoked to explain their origin. However, genetic recombination can constrain the ability of divergent selection to produce reproductive isolation in sympatry. Recombination breaks up favorable combinations of traits (”adaptive suites”) if individual traits are...

Imprinting of Hatchery-Reared Salmon to Targeted Spawning Locations: A New Embryonic Imprinting Paradigm for Hatchery Programs

Creator:: Dittman, Andrew H., Pearsons, Todd N., May, Darran, Couture, Ryan B., and Noakes, David L. G.
Abstract:: Straying by hatchery-reared salmon is a major concern for conservation and recovery of many salmon populations. Fisheries managers have attempted to minimize negative ecological and genetic interactions between hatchery and wild fish by using parr-smolt acclimation facilities to ensure successful olfactory imprinting and homing fidelity. However, the effectiveness of offsite...

Effect of short-term decrease in water temperature on body temperature and involvement of testosterone in steelhead and rainbow trout, Oncorhynchus mykiss

Creator:: Miura, Go, Munakata, Arimune, Yada, Takashi, Schreck, Carl B., Noakes, David L. G., and Matsuda, Hiroyuki
Abstract:: The Pacific salmonid species Oncorhynchus mykiss is separated into a migratory form (steelhead trout) and a non-migratory form (rainbow trout). A decrease in water temperature is likely a cue triggering downstream behavior in the migratory form, and testosterone inhibits onset of this behavior. To elucidate differences in sensitivity to water...

Fine-scale parallel patterns in diversity of small benthic Arctic charr (Salvelinus alpinus) in relation to the ecology of lava/groundwater habitats

Creator:: Kristjansson, Bjarni K., Skulason, Skuli, Snorrason, Sigurour S., and Noakes, David L. G.
Abstract:: It is critical to study factors that are important for origin and maintenance of biological diversity. A comparative approach involving a large number of populations is particularly useful.We use this approach to study the relationship between ecological factors and phenotypic diversity in Icelandic Arctic charr (Salvelinus alpinus). Numerous populations of...

Salinity effects on plasma ion levels, cortisol, and osmolality in Chinook salmon following lethal sampling

Creator:: Stewart, Heather A., Noakes, David L. G., Cogliati, Karen M., Peterson, James T., Iversen, Martin H., and Schreck, Carl B.
Abstract:: Studies on hydromineral balance in fishes frequently employ measurements of electrolytes following euthanasia. We tested the effects of fresh- or salt-water euthanasia baths of tricaine mesylate (MS-222) on plasma magnesium (Mg²⁺) and sodium (Na⁺) ions, cortisol and osmolality in fish exposed to saltwater challenges, and the ion and steroid hormone...

Evidence for geomagnetic imprinting as a homing mechanism in Pacific salmon

Creator:: Putnam, Nathan F., Lohmann, Kenneth J., Putnam, Emily M., Quinn, Thomas P., Klimley, A. Peter, and Noakes, David L. G.
Abstract:: In the final phase of their spawning migration, Pacific salmon use chemical cues to identify their home river, but how they navigate from the open ocean to the correct coastal area has remained enigmatic [1]. To test the hypothesis that salmon imprint on the magnetic field that exists where they...
