To deal with the predictable changes in
their environments, all taxonomic groups have evolved genetically programmed
timing mechanisms. These govern seasonal cycles in physiology and behaviour that
optimise survival and reproductive success, and have been formally described as
circannual rhythms. Experimentally, under conditions of constant day length and
temperature, circannual rhythms of many species continue to be expressed, even
throughout the life cycle, illustrating the fundamental endogenous control.
