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.
General description of the sites where the species is found (ecosystem, forest, environment or microhabitat). Includes realm (e.g Terrestrial etc) and climatic information (e.g Boreal); also includes requirements and tolerances; horizontal and vertical (altitudinal) distribution. Also includes information referring to territorial extension of the individual or group in terms of its activities (feeding, mating, etc.), associated mostly to vertebrates.
Describes the likelihood of the species becoming extinct in the present day or in the near future. Population size is treated under Population Biology, and trends in population sizes are treated under Trends. However, this is the preferred element if an object includes all of these things and details about conservation listings.
