Chapman (4) observed that the levels assumed by a population of poikilothermic animals depended upon the 'resistance' that the environment presented to the 'biotic potential' (ability of organisms to survive and reproduce) of the organisms of that population. He postulated that a modification of Ohm's law for electrical resistance could be used in the calculation of the resistance that any environment presents to a species. Thus the degree to which various environments affect the biotic potential of a species could be expressed by a series of exponential factors.
