Biological clocks drive the physiology and behaviour of all organisms, from bacteria to humans. Much attention has focused on the circadian 24 h clock, and rapid progress made in defining key molecular components that regulate our rhythmic physiology. The circadian clock also drives a linked timing system that controls annual cycles of hormone secretion and metabolism, this is most evident in wild species, such as hibernating mammals. Annual cycles are also key feature of dome...
