Introduced to Lake Allos in 1924, Arctic charr exhibit remarkable metabolic adaptations within just a century. These fish showcase rapid physiological changes, attributed mainly to their phenotypic plasticity, resulting in distinct body shapes. Notably, juveniles from Lake Allos consistently demonstrate elevated metabolic rates, even under controlled conditions. This research underscores the species' ability to swiftly adapt to their ever-changing environmental landscape.
