Fisheries-induced evolutionary changes in maturation reaction norms in North Sea sole Solea solea (2007, background): “Because of the difficulty of measuring selection differentials (Sinclair et al. 2002) and heritabilities, especially in the wild, the rate of evolution is not well understood.”
Spatial and temporal scales of adaptive divergence in marine fishes and the implications for conservation (2006, background): “These changes are exceedingly rapid, i.e. on the order of 0 6–1 5 H. Intensively exploited Atlantic cod from the Gulf of St Lawrence display greatly reduced size at age that persisted after a moratorium on harvest (Sinclair et al., 2002).”
Fisheries-induced adaptive change in reproductive investment in North Sea plaice (Pleuronectes platessa)? (2005, background): “This index, however, does not necessarily track changes in growth rate among age groups, as it does not take account of changes in (size-selective) mortality (Rijnsdorp 1999; Sinclair et al. 2002).”
Marine Fish Population Collapses: Consequences for Recovery and Extinction Risk (2004, background): “Cod in some areas have also become smaller at a given age (Sinclair et al. 2002) and are reproducing at smaller sizes than those observed historically (COSEWIC 2003).”
Disentangling the effects of size-selective mortality, density, and temperature on length-at-age (2002, background): “Indices of size selection were developed from a database of backcalculated length-at-age (Sinclair et al. 2002).”
Fishing‐induced evolution of growth: concepts, mechanisms and the empirical evidence (2012, background): “…harvesting may lead to differential mortalities within a cohort, for example when the largest members of a given age class are harvested and the smaller ones survive, leading to demographic change in mean trait values over time even within one cohort (Sinclair et al. 2002; Swain et al. 2007).”
Otolith science entering the 21st century (2005, background): “However, the most comprehensive study of this type was one based on more than 13 000 back-calculations of cod otoliths, which were used to estimate both the direction and magnitude of size-selective mortality as a result of fishing (Sinclair et al. 2002).”
Assessing changes in age and size at maturation in collapsing populations of Atlantic cod (Gadus morhua) (2005, unknown): “…genetic variability in growth exists and that growth rates may thus evolve as a response to selective harvesting (Conover and Munch 2002; also see Sinclair et al. 2002; Munch et al. 2005), it is very unlikely that growth variation in a species exposed to an environment as unpredictable as that…”
A statistical framework to explore ontogenetic growth variation among individuals and populations: a marine fish example (2015, methodology): “…we only fit a linear Age-at-capture term and explore potential directional (positive and negative) selection; quadratic or nonlinear terms could potentially also be fitted to explore other types of selection, such as stabilizing or disruptive or a combination of these (e.g., Sinclair et al. 2002a).”
