Resource competition induces heterogeneity and can increase cohort survivorship: selection-event duration matters.
Oecologia. 2013 Aug 3;
Authors: Gosselin JL, Anderson JJ
Determining when resource competition increases survivorship can reveal processes underlying population dynamics and reinforce the importance of heterogeneity among individuals in conservation. We ran an experiment mimicking the effects of competition in a growing season on survivorship during a selection event (e.g., overwinter starvation, drought).
Injuries from non-retention in gillnet fisheries suppress reproductive maturation in escaped fish.
PLoS One. 2013;8(7):e69615
Authors: Baker MR, Swanson P, Young G
Exploitation of fisheries resources has unintended consequences, not only in the bycatch and discard of non-target organisms, but also in damage to targeted fish that are injured by gear but not landed (non-retention). Delayed mortality due to non-retention represents lost reproductive potential in exploited stocks, while not contributing to harvest.
Identifying preservation and restoration priority areas for desert fishes in an increasingly invaded world.
Environ Manage. 2013 Mar;51(3):631-41
Authors: Pool TK, Strecker AL, Olden JD
A commonly overlooked aspect of conservation planning assessments is that wildlife managers are increasingly focused on habitats that contain non-native species. We examine this management challenge in the Gila River basin (150,730 km(2)), and present a new planning strategy for fish conservation.
Genomic resource development for shellfish of conservation concern.
Mol Ecol Resour. 2013 Mar;13(2):295-305
Authors: Timmins-Schiffman EB, Friedman CS, Metzger DC, White SJ, Roberts SB
Effective conservation of threatened species depends on the ability to assess organism physiology and population demography. To develop genomic resources to better understand the dynamics of two ecologically vulnerable species in the Pacific Northwest of the United States, larval transcriptomes were sequenced for the pinto abalone, Haliotis kamtschatkana kamtschatkana, and the Olympia oyster, Ostrea lurida.
Effects of the herbicide imazapyr on juvenile Oregon spotted frogs.
Environ Toxicol Chem. 2013 Jan;32(1):228-35
Authors: Yahnke AE, Grue CE, Hayes MP, Troiano AT
Conflict between native amphibians and aquatic weed management in the Pacific Northwest is rarely recognized because most native stillwater-breeding amphibian species move upland during summer, when herbicide application to control weeds in aquatic habitats typically occurs.
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.
