Ecologically, morphologically and genetically distinct populations within single taxa often coexist in postglacial lakes and have provided important model systems with which to investigate ecological and evolutionary processes such as niche partitioning and ecological speciation.
Can interbreeding of wild and artificially propagated animals be prevented by using broodstock selected for a divergent life history?
Evol Appl. 2012 Nov;5(7):705-19
Authors: Seamons TR, Hauser L, Naish KA, Quinn TP
TWO STRATEGIES HAVE BEEN PROPOSED TO AVOID NEGATIVE GENETIC EFFECTS OF ARTIFICIALLY PROPAGATED INDIVIDUALS ON WILD POPULATIONS: (i) integration of wild and captive populations to minimize domestication selection and (ii) segregation of released individuals from the wild population to minimize interbreeding.
Impacts of ocean acidification on marine seafood.
Trends Ecol Evol. 2012 Nov 1;
Authors: Branch TA, Dejoseph BM, Ray LJ, Wagner CA
Ocean acidification is a series of chemical reactions due to increased CO(2) emissions. The resulting lower pH impairs the senses of reef fishes and reduces their survival, and might similarly impact commercially targeted fishes that produce most of the seafood eaten by humans.
The paper, “Elevated pCO2 causes developmental delay in early larval Pacific oysters, Crassostrea gigas“, is included in an upcoming special issue on ocean acidification in the journal Marine Biology. I did the research in Emily Carrington’s lab in Friday Harbor during the summer of 2011 with the help of researcher Michael “Moose” O’Donnell. Other co-authors and contributors are SAFS professors Carolyn Friedman and Steven Roberts.Read more
Trade-offs in the design of fishery closures: management of silky shark bycatch in the eastern Pacific Ocean tuna fishery.
Conserv Biol. 2009 Jun;23(3):626-35
Authors: Watson JT, Essington TE, Lennert-Cody CE, Hall MA
Bycatch–the incidental catch of nontarget species–is a principal concern in marine conservation and fisheries management. In the eastern Pacific Ocean tuna fishery, a large fraction of nonmammal bycatch is captured by purse-seine gear when nets are deployed around floating objects.
Synchronous Cycling of Ichthyophoniasis with Chinook Salmon Density Revealed during the Annual Yukon River Spawning Migration
Transactions of the American Fisheries Society, Volume 141, Issue 3, 2012

Populations of Chinook salmon Oncorhynchus tshawytscha in the Yukon River declined by more than 57% between 2003 and 2010, probably the result of a combination of anthropogenic and environmental factors.
Pattern and process of biotic homogenization in the New Pangaea.
Proc Biol Sci. 2012 Oct 10;
Authors: Baiser B, Olden JD, Record S, Lockwood JL, McKinney ML
Human activities have reorganized the earth’s biota resulting in spatially disparate locales becoming more or less similar in species composition over time through the processes of biotic homogenization and biotic differentiation, respectively. Despite mounting evidence suggesting that this process may be widespread in both aquatic and terrestrial systems, past studies have predominantly focused on single taxonomic groups at a single spatial scale.
In this month’s issue of the Journal of Shellfish Research, results from a research project carried out in the lab section of FISH441: Integrative Environmental Physiology was published. David Metzger and Paul Pratt (now both SAFS alum) are primary authors on the paper entitled: Characterizing the Effects of Heavy Metal and Vibrio Exposure on Hsp70 Expression in Crassostrea gigas Gill Tissue.Read more
Characterizing short read sequencing for gene discovery and RNA-Seq analysis in Crassostrea gigas.
Comp Biochem Physiol Part D Genomics Proteomics. 2012 Jun;7(2):94-9
Authors: Gavery MR, Roberts SB
Advances in DNA sequencing technology have provided opportunities to produce new transcriptomic resources for species that lack completely sequenced genomes. However, there are limited examples that rely solely on ultra-short read sequencing technologies (e.g.
A drawback to the attention garnered by high-profile invasive species is the tendency to infer that every non-native species is bad news, the inverse assumption being that all native species must be ‘good’. While this storyline works well for Hollywood films and faerie tales, in ecology the truth is rarely that simple. A new review article that Julian Olden and colleagues at NOAA Fisheries co-authored in the September issue of Frontiers in Ecology and the Environment, describes the challenges and heartbreaks when native species run amok in the sense of having negative ecological impacts we typically associate with non-native species.Read more
