Describes biorhythms - those states or conditions characterised by regular repetition in time, whether on the scale of seconds, hours, days, or seasons. It could also cover phenomena such as "plant flowering" or "chewing rates". Life cycles are treated in the field for Life Cycle. Seasonal migration and reproduction are usually treated separately.
