Crangon crangon, newly hatched larvae. Smoothing function (S) obtained by generalized additive model (GAM) for larval carbon content (C, μg larva−1) exploring the effects of pre-hatching factors [a initial egg biomass and b incubation temperature] and the environmental conditions prevailing at the time of hatching [c temperature and d phytoplankton biomass]. These plots allow evaluating the relationships between explanatory variables (x-axis) and adjusted residuals of dependent variable (carbon, y-axis). Solid line estimated smoothing function; dotted lines 95 % confidence intervals. Total variance is quantified by values of r 2, the significance of the smoothing function by values of F and P; dots represent mean values, in all cases n = 128.
