intensity of body moult A intensity of body moult is a measurement datum that describes the intensity of the periodic replacement of epidermis (skin), pelage (hair, fur, wool), or other external layer. In some species, other body parts may be shed, for example, wings in some insects. Examples include old feathers in birds, old hairs in mammals (especially dogs and other canidae), old skin in reptiles, and the entire exoskeleton in arthropods. http://en.wikipedia.org/wiki/Moult 20110823: this term initially refered only to bird in its definition. We may also need to create a moulting process. 20110823, MC: need to check on the unit for this. If it has a unit it should be asserted under scalar measurement datum
