Pesticides in urban streams and early life stages of Pacific coho salmon.
Environ Toxicol Chem. 2013 Apr;32(4):920-31
Authors: King KA, Grue CE, Grassley JM, Fisk RJ
Pesticides are frequently detected in urban streams and are believed to be primarily the result of homeowner use. Although concentrations in most cases are low (<1 µg/L), there is concern that pesticide inputs threaten efforts to restore and enhance salmon habitat.
Meiotic maps of sockeye salmon derived from massively parallel DNA sequencing.
BMC Genomics. 2012;13:521
Authors: Everett MV, Miller MR, Seeb JE
BACKGROUND: Meiotic maps are a key tool for comparative genomics and association mapping studies. Next-generation sequencing and genotyping by sequencing are speeding the processes of SNP discovery and the development of new genetic tools, including meiotic maps for numerous species.
Efficacy, fate, and potential effects on salmonids of mosquito larvicides in catch basins in Seattle, Washington.
J Am Mosq Control Assoc. 2012 Sep;28(3):206-18
Authors: Sternberg M, Grue C, Conquest L, Grassley J, King K
We investigated the efficacy, fate, and potential for direct effects on salmonids of 4 common mosquito larvicides (Mosquito Dunks and Bits (AI: Bacillis thuringiensis var. israelensis, [Bti]), VectoLex WSP (AI: Bacillus sphaericus [Bs], VectoLex CG [AI: Bs], and Altosid Briquets [AI: s-methoprene]) in Seattle, WA, during 3 summers.

Evidence for an amoeba-like infectious stage of Ichthyophonus sp. and description of a circulating blood stage: a probable mechanism for dispersal within the fish host.
J Parasitol. 2013 Apr;99(2):235-40
Authors: Kocan R, LaPatra S, Hershberger P
Small amoeboid cells, believed to be the infectious stage of Ichthyophonus sp., were observed in the bolus (stomach contents) and tunica propria (stomach wall) of Pacific staghorn sculpins and rainbow trout shortly after they ingested Ichthyophonus sp.-infected tissues.
Pesticides in Urban Streams and Prespawn Mortality of Pacific Coho Salmon.
Arch Environ Contam Toxicol. 2013 Jun 7;
Authors: King KA, Grue CE, Grassley JM, Hearsey JW
The listing of several runs of Pacific salmon as threatened or endangered and associated federal, state, and local efforts to restore/enhance salmon habitat in the Pacific Northwest make it imperative that the factors associated with these population declines are understood.

Hybridization between genetically modified Atlantic salmon and wild brown trout reveals novel ecological interactions

Interspecific hybridization is a route for transgenes from genetically modified (GM) animals to invade wild populations, yet the ecological effects and potential risks that may emerge from such hybridization are unknown.
Characterization of genes involved in ceramide metabolism in the Pacific oyster (Crassostrea gigas).
BMC Res Notes. 2012;5:502
Authors: Timmins-Schiffman E, Roberts S
BACKGROUND: The lipid signaling molecule, ceramide, is a key component of the vertebrate stress response, however, there is limited information concerning its role in invertebrate species. In order to identify genes involved in ceramide metabolism in bivalve molluscs, Pacific oyster genomic resources were examined for genes associated with ceramide metabolism and signaling.

How does the availability of food affect the selectivity of the consumer? It has long been known that survival of prey can depend on their density, as predators become satiated or cannot catch them all. In addition, many studies have shown that predators are selective, tending to kill and consume some species or sizes of prey over others, but very few are examples of prey density driving patterns of selection by predators.
