Notes:
Arctic charr Salvelinus alpinus juveniles reared from eggs collected from four Scottish populations showed inherited variation in their expression of trophic morphology, measured as a suite of eight characteristics of the head and mouth, before their first exogenous feeding. This demonstrated a genetic component to trophic morphology expression. During a period of 5 months following first feeding, typified by rapid growth, the differential between groups exposed to a common rearing and feeding environment was reduced significantly. It was concluded that this was the result of common environmental exposure acting on phenotypic plasticity in trophic morphology.
