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
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 their maximum sustainable yield.
Estimation of genotyping error rate from repeat genotyping, unintentional recaptures and known parent-offspring comparisons in 16 microsatellite loci for brown rockfish (Sebastes auriculatus).
Mol Ecol Resour. 2012 Nov;12(6):1114-23
Authors: Hess MA, Rhydderch JG, LeClair LL, Buckley RM, Kawase M, Hauser L
Genotyping errors are present in almost all genetic data and can affect biological conclusions of a study, particularly for studies based on individual identification and parentage.
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
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.
Impacts of ocean acidification on marine seafood

A review of the effects of ocean acidification that arose from
graduate student participants in the 2011 Bevan Series on Sustainable
Seafood has just been published in Trends in Ecology and Evolution.
Ocean acidification is a series of chemical reactions due to
increased CO2 emissions.
The Soundscapes of Lakes across an Urbanization Gradient.
PLoS One. 2013;8(2):e55661
Authors: Kuehne LM, Padgham BL, Olden JD
BACKGROUND/METHODOLOGY: A significant implication of increasing urbanization is anthropogenic noise pollution. Although noise is strongly associated with disruption of animal communication systems and negative health effects for humans, the study of these consequences at ecologically relevant spatial and temporal scales (termed soundscape ecology) is in early stages of application.
Characterizing coastal foodwebs with qualitative links to bridge the gap between the theory and the practice of ecosystem-based management

Tools that integrate the complexity of natural systems are needed to facilitate ecosystem-based management (EBM).
Spatial Segregation of Spawning Habitat Limits Hybridization between Sympatric Native Steelhead and Coastal Cutthroat Trout
T. W. Buehrens, J. Glasgow, C. O. Ostberg, T. P. Quinn
Native Coastal Cutthroat Trout Oncorhynchus clarkii clarkii and Coastal Steelhead O. mykiss irideus hybridize naturally in watersheds of the Pacific Northwest yet maintain species integrity. Partial reproductive isolation due to
differences in spawning habitat may limit hybridization between these species, but this process is poorly understood.
Dispersal and tributary immigration by juvenile coho salmon contribute to spatial expansion during colonisation

Accepted for publication July 12, 2012
Anadromous fishes are frequently restricted by artificial barriers to movement such as dams and culverts, so measuring dispersal helps identify sites where improved connectivity could promote range expansion and population viability.
Summer emigration and resource acquisition within a shared nursery lake by sockeye salmon (Oncorhynchus nerka) from historically discrete rearing environments
R.K. Simmons,* T.P. Quinn, L.W. Seeb, D.E. Schindler, and R. Hilborn. School of Aquatic and Fishery Sciences, Box 355020, University of Washington, Seattle, WA 98195, USA.
Many fish species disperse broadly during juvenile life history stages. While this may enable persistence in variable environments, it may also produce novel competitive interactions in recipient habitats that contain conspecifics from other populations.
