Modelling the effect of temperature on hatching and settlement patterns of meroplanktonic organisms: the case of octopus

The duration of embryonic development and the planktonic stage of meroplanktonic species is highly temperature dependent and thus the seasonal temperature oscillations of temperate regions greatly affect the patterns of hatching and benthic settlement. Based on data from the literature on e...
