Brain Acetylcholinesterase Activity in Shiner Perch (Cymatogaster aggregata) and Juvenile Chinook Salmon (Oncorhynchus tshawytscha) After Application of Carbaryl to Control Burrowing Shrimp Within Willapa Bay, Washington.

Brain Acetylcholinesterase Activity in Shiner Perch (Cymatogaster aggregata) and Juvenile Chinook Salmon (Oncorhynchus tshawytscha) After Application of Carbaryl to Control Burrowing Shrimp Within Willapa Bay, Washington.
Arch Environ Contam Toxicol. 2013 Sep 17;
Authors: Troiano AT, King KA, Grue CE, Grassley JM, Ekblad CJ
Abstract
Carbaryl has been applied in Willapa Bay, Washington, for five decades to control burrowing shrimp (Neotrypaea californiensis and Upogebia pugettensis) on commercial oyster (Crassostrea gigas) beds.

Relationship between effective population size, inbreeding and adult fitness-related traits in a steelhead (Oncorhynchus mykiss) population released in the wild.
Mol Ecol. 2013 Mar;22(5):1295-309
Authors: Naish KA, Seamons TR, Dauer MB, Hauser L, Quinn TP
Abstract
Inbreeding is of concern in supportive breeding programmes in Pacific salmonids, Oncorhynchus spp, where the number of breeding adults is limited by rearing space or poor survival to adulthood, and large numbers are released to supplement wild stocks and fisheries.

Citation patterns of a controversial and high-impact paper: Worm et al. (2006) “Impacts of biodiversity loss on ocean ecosystem services”.
PLoS One. 2013;8(2):e56723
Authors: Branch TA
Abstract
Citation patterns were examined for Worm et al. 2006 (Science 314:787-790), a high-impact paper that focused on relationships between marine biodiversity and ecosystem services. This paper sparked much controversy through its projection, highlighted in the press release, that all marine fisheries would be collapsed by 2048.

High-throughput sequencing and pathway analysis reveal alteration of the pituitary transcriptome by 17α-ethynylestradiol (EE2) in female coho salmon, Oncorhynchus kisutch.

High-throughput sequencing and pathway analysis reveal alteration of the pituitary transcriptome by 17α-ethynylestradiol (EE2) in female coho salmon, Oncorhynchus kisutch.
Aquat Toxicol. 2013 Aug 9;142-143C:146-163
Authors: Harding LB, Schultz IR, Goetz GW, Luckenbach JA, Young G, Goetz FW, Swanson P
Abstract
Considerable research has been done on the effects of endocrine disrupting chemicals (EDCs) on reproduction and gene expression in the brain, liver and gonads of teleost fish, but information on impacts to the pituitary gland are still limited despite its central role in regulating reproduction.

How stock of origin affects performance of individuals across a meta-ecosystem: an example from sockeye salmon.
PLoS One. 2013;8(3):e58584
Authors: Griffiths JR, Schindler DE, Seeb LW
Abstract
Connectivity among diverse habitats can buffer populations from adverse environmental conditions, influence the functioning of meta-ecosystems, and ultimately affect the reliability of ecosystem services. This stabilizing effect on populations is proposed to derive from complementarity in growth and survival conditions experienced by individuals in the different habitats that comprise meta-ecosystems.

Effects of management tactics on meeting conservation objectives for Western North American groundfish fisheries.
PLoS One. 2013;8(2):e56684
Authors: Melnychuk MC, Banobi JA, Hilborn R
Abstract
There is considerable variability in the status of fish populations around the world and a poor understanding of how specific management characteristics affect populations. Overfishing is a major problem in many fisheries, but in some regions the recent tendency has been to exploit stocks at levels below their maximum sustainable yield.

Predation by bears drives senescence in natural populations of salmon.
PLoS One. 2007;2(12):e1286
Authors: Carlson SM, Hilborn R, Hendry AP, Quinn TP
Abstract
Classic evolutionary theory predicts that populations experiencing higher rates of environmentally caused (“extrinsic”) mortality should senesce more rapidly, but this theory usually neglects plausible relationships between an individual’s senescent condition and its susceptibility to extrinsic mortality.
