Research on food webs increasingly relies on sampling biomarkers (stable isotopes and fatty acids) in consumers and their potential prey. In studies of macroalgal and seagrass biomarkers in the northeast Pacific, Dethier and coworkers found substantial variation in biomarkers across dates and sites.
Branch TA, Hively DJ, Hilborn R (2013) Is the ocean food provision index biased? Nature 495:E5-E6
How close to maximum sustainable food provision is current seafood harvest from the world’s oceans? Halpern et al.  suggest that the answer is 25% from a global index of food provision, part of their multifaceted index of ocean health. Rigorous methods used for management, however, demonstrate that their food provision index is uncorrelated with actual food provision, and that global ocean food provision is in the range of 71–95%.
Temporal variation in selection on body length and date of return in a wild population of coho salmon, Oncorhynchus kisutch.
BMC Evol Biol. 2012;12:116
Authors: Kodama M, Hard JJ, Naish KA
BACKGROUND: A number of studies have measured selection in nature to understand how populations adapt to their environment; however, the temporal dynamics of selection are rarely investigated.
Phenotype flexibility in wild fish: Dolly Varden regulate assimilative capacity to capitalize on annual pulsed subsidies.

Authors: Armstrong JB, Bond MH
Large digestive organs increase rates of energy gain when food is plentiful but are costly to maintain and increase rates of energy loss when food is scarce. The physiological adaptations to this trade-off differ depending on the scale and predictability of variation in food abundance.
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
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.

Selective exploitation can cause adverse ecological and evolutionary changes in wild populations and also affect sex ratios but few studies have empirically documented skewed sex ratios in exploited fishes (other than species with extreme sexual size dimorphism, SSD). To investigate the possibility of sex-selective fishing on Alaskan sockeye salmon Oncorhynchus nerka, we assessed sex ratios in fish at two spatial scales: within each of five fishing districts and among 13 breeding populations in one of these districts.
Reproductive success of captively bred and naturally spawned Chinook salmon colonizing newly accessible habitat.
Evol Appl. 2013 Feb;6(2):165-79
Authors: Anderson JH, Faulds PL, Atlas WI, Quinn TP
Captively reared animals can provide an immediate demographic boost in reintroduction programs, but may also reduce the fitness of colonizing populations. Construction of a fish passage facility at Landsburg Diversion Dam on the Cedar River, WA, USA, provided a unique opportunity to explore this trade-off.
Stage-specific effects of androgens and estradiol-17beta on the development of late primary and early secondary ovarian follicles of coho salmon (Oncorhynchus kisutch) in vitro.
Biol Reprod. 2012 Sep;87(3):64
Authors: Forsgren KL, Young G
An in vitro system was used to analyze the effects of sex steroids on the development of primary (late perinucleolar stage) and early secondary, previtellogenic (early cortical alveolus stage) ovarian follicles of coho salmon cultured for up to 21 days.
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.
