Early developmental plasticity and integrative responses in arctic charr ( Salvelinus alpinus): effects of water velocity on body size and shape
Abstract Environmental conditions such as temperature and water velocity may induce changes among alternative developmental pathways, i.e. phenotypic responses, in vertebrates. However, the extent to which the environment induces developmental plasticity and integrated developmental responses during...
