    Genomic signatures predict migration and spawning failure in wild Canadian salmon (2011)

    Description: Long-term population viability of Fraser River sockeye salmon (Oncorhynchus nerka) is threatened by unusually high levels of mortality as they swim to their spawning areas before they spawn. Functional genomic studies on biopsied gill tissue from tagged wild adults that were tracked through ocean and river environments revealed physiological profiles predictive of successful migration and spawning. We identified a common genomic profile that was correlated with survival in each study. In ocean-tagged fish, a mortality-related genomic signature was associated with a 13.5-fold greater chance of dying en route. In river-tagged fish, the same genomic signature was associated with a 50% increase in mortality before reaching the spawning grounds in one of three stocks tested. At the spawning grounds, the same signature was associated with 3.7-fold greater odds of dying without spawning. Functional analysis raises the possibility that the mortality-related signature reflects a viral infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miller, Kristina M -- Li, Shaorong -- Kaukinen, Karia H -- Ginther, Norma -- Hammill, Edd -- Curtis, Janelle M R -- Patterson, David A -- Sierocinski, Thomas -- Donnison, Louise -- Pavlidis, Paul -- Hinch, Scott G -- Hruska, Kimberly A -- Cooke, Steven J -- English, Karl K -- Farrell, Anthony P -- New York, N.Y. -- Science. 2011 Jan 14;331(6014):214-7. doi: 10.1126/science.1196901.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Genetics Section, Pacific Biological Station, 3190 Hammond Bay Road, Fisheries and Oceans Canada, Nanaimo, BC V9T 6N7, Canada. kristi.miller@dfo-mpo.gc.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21233388" target="_blank"〉PubMed〈/a〉

    Differences in thermal tolerance among sockeye salmon populations (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-04-02
    Description: Climate change-induced increases in summer water temperature have been associated with elevated mortality of adult sockeye salmon (Oncorhynchus nerka) during river migration. We show that cardiorespiratory physiology varies at the population level among Fraser River sockeye salmon and relates to historical environmental conditions encountered while migrating. Fish from populations with more challenging migratory environments have greater aerobic scope, larger hearts, and better coronary supply. Furthermore, thermal optima for aerobic, cardiac, and heart rate scopes are consistent with the historic river temperature ranges for each population. This study suggests that physiological adaptation occurs at a very local scale, with population-specific thermal limits being set by physiological limitations in aerobic performance, possibly due to cardiac collapse at high temperatures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eliason, Erika J -- Clark, Timothy D -- Hague, Merran J -- Hanson, Linda M -- Gallagher, Zoe S -- Jeffries, Ken M -- Gale, Marika K -- Patterson, David A -- Hinch, Scott G -- Farrell, Anthony P -- New York, N.Y. -- Science. 2011 Apr 1;332(6025):109-12. doi: 10.1126/science.1199158.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of British Columbia, 6270 University Boulevard, Vancouver, BC, Canada, V6T 1Z4. eliason@zoology.ubc.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21454790" target="_blank"〉PubMed〈/a〉
