annual cycles to that of the synchronizing role of a Zeitgeber, in the sense of Aschoff (1955), for an innate quasi-annual reproductive periodicity. Photoperiodism, thus defined, is a part of the large and fascinating field of annual biochronometry. Whether an organism has an annual cycle that is generated by an annual environmental periodicity or simply phased or synchronized by it, the most conspicious reliable annual en vironmental periodicity at mid- and high-latitudes is the annual change… Expand
