Fig. 2 Total length (a) and survival probability (b) of the marbled goby larvae at successive dph. White bars represent a family selected for the blue spot on the male dorsal fin and reared at 18 °C; black bars represent a family selected for body size and reared at 18 °C; grey bars represent a family selected for body size and reared in captivity at 24 °C. The warmer line (24 °C) was lost between 130 and 160 dph. Each family has offspring from the same mother and two different fathers (double bars). Since survival and size remained almost constant after 160 dph successive measures between 160 and 360 dph are omitted and only the final values at 360 dph are reported. Error bars in a represent the standard error of the mean
