“…Using these discriminant functions, only 22% of the recruits were correctly reclassified, which, with few exceptions, lie at the borders of the discriminant function analysis space generated by larvae ratios in the natal core of recruit statoliths collected from the northern region may be interpreted in relation to the presence of a persistent upwelling shadow inside Antofagasta Bay , Lagos et al 2008). This agrees with the significant reduction in Ba/Ca from southern to northern recruit statoliths, and might be associated with the negative effect of temperature in the incorporation of Ba as has been reported in studies conducted in gastropods (Zacherl et al 2003a, Zumholz et al 2007, Lloyd et al 2008 and bivalves (Carson 2010). Interestingly, pre-hatch larval statoliths (where individuals are fixed in place) do not show this pattern, and instead show a significant increase of the Ba/Ca ratio from southern to northern populations.…”
