Small-scale biocomplexity in coastal Atlantic cod supporting a Darwinian perspective on fisheries management
Open accessAbstract
Harvesting of marine resources raises concerns about how to identify and preserve biocomplexity, including the diversity of life histories found within and among wild populations of a species. In order to fully accomplish this, there is a need to elucidate the underlying causes of phenotypic variation, and how this variation responds to environmental changes. In general, both evolutionary (genetic) and nonevolutionary (plastic) responses may occur. Plastic responses to environmental change are expected to shift the phenotype along a reaction norm, while an evolutionary response is expected to shift the reaction norm itself. Here, we assess the maturation patterns of coastal Atlantic cod (Gadus morhua) in Skagerrak, where studies using neutral markers have revealed genetically differentiated populations of this harvested fish within tens of kilometres of coastline. Our results suggest that physiological state prior to the spawning season, as well as juvenile growth, both influence the probability of completing sexual maturation at a given age. Furthermore, our results point towards a spatial structuring of this plasticity (i.e. the maturation reaction norms) comparable with population connectivity inferred from neutral markers. We argue that such fine‐scale biocomplexity calls for a Darwinian approach to fisheries management.

Atlantic cod fits in this category, having a high scope for local adaptations but limited scope for phenotypic plasticity.
“Atlantic cod also fits in this category, having a high scope for local adaptations (Knutsen et al., 2003;Olsen et al., 2008Olsen et al., , 2009)).”
From Evolutionary and ecological constraints of fish spawning habitats (2015) · cites this paper as Olsen et al., 2008
The Discussion (page not provided) finds fine-scale differences in coastal cod life histories indicative of a genetic component, supporting the possibility of local adaptation. It does not establish a high scope for adaptation or limited phenotypic plasticity; the Discussion instead reports that plasticity influences cod maturation. The verbatim citing sentence does not explicitly make the limited-plasticity claim. (LLM, conf=0.86)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
