Diet-induced developmental plasticity in life histories and energy metabolism in a beetle

Adaptive phenotypic plasticity, has been recognized as an important strategy by which organisms maximize fitness in variable environments, which vary through development. A disassociation among stages should represent a null effect of the environment experienced during early ontogeny in the expressi...
