Spatial Segregation of Spawning Habitat Limits Hybridization between Sympatric Native Steelhead and Coastal Cutthroat Trout

Spatial Segregation of Spawning Habitat Limits Hybridization between Sympatric Native Steelhead and Coastal Cutthroat Trout
T. W. Buehrens, J. Glasgow, C. O. Ostberg, T. P. Quinn
Abstract
Native Coastal Cutthroat Trout Oncorhynchus clarkii clarkii and Coastal  Steelhead O. mykiss irideus hybridize naturally in watersheds of the Pacific Northwest yet maintain species integrity. Partial reproductive isolation due to
differences in spawning habitat may limit hybridization between these species, but this process is poorly understood.

Dispersal and tributary immigration by juvenile coho salmon contribute to spatial expansion during colonisation

Dispersal and tributary immigration by juvenile coho salmon contribute to spatial expansion during colonisation
Joseph H. Anderson, George R. Pess, Peter M. Kiffney, Todd R. Bennett, Paul L. Faulds, William I. Atlas*, Thomas P. Quinn
Accepted for publication July 12, 2012
Abstract
Anadromous fishes are frequently restricted by artificial barriers to movement such as dams and culverts, so measuring dispersal helps identify sites where improved connectivity could promote range expansion and population viability.

Summer emigration and resource acquisition within a shared nursery lake by sockeye salmon (Oncorhynchus nerka) from historically discrete rearing environments

Summer emigration and resource acquisition within a shared nursery lake by sockeye salmon (Oncorhynchus nerka) from historically discrete rearing environments
R.K. Simmons,* T.P. Quinn, L.W. Seeb, D.E. Schindler, and R. Hilborn. School of Aquatic and Fishery Sciences, Box 355020, University of Washington, Seattle, WA 98195, USA.
Abstract
Many fish species disperse broadly during juvenile life history stages. While this may enable persistence in variable environments, it may also produce novel competitive interactions in recipient habitats that contain conspecifics from other populations.

Single-nucleotide polymorphisms reveal distribution and migration of Chinook salmon (Oncorhynchus tshawytscha) in the Bering Sea and North Pacific Ocean (publication)

Larson, W. A., F. M. Utter, K. W. Myers, W. D. Templin, J. E. Seeb, C. M. Guthrie, A. V. Bugaev, and L. W. Seeb. 2013. Single-nucleotide polymorphisms reveal distribution and migration of Chinook salmon (Oncorhynchus tshawytscha) in the Bering Sea and North Pacific Ocean Canadian Journal of Fisheries and Aquatic Sciences 70:128-141.
Abstract
We genotyped Chinook salmon (Oncorhynchus tshawytscha) from the Bering Sea and North Pacific Ocean for 43 singlenucleotide polymorphisms (SNPs) to investigate seasonal distribution and migration patterns.
