WebSurvivorship curves show the distribution of individuals in a population according to age. Humans and most mammals have a Type I survivorship curve because death primarily occurs in the older years. Birds have a Type II survivorship curve, as death at any age is equally probable. WebWhen the logarithm of the number of survivors is plot against age, then three distinct, idealized “types” are distinguished (Type-I, Type-II and Type-III (Deevey 1947 ); Fig. 1a ). Survival curves, by deduction, give some indication of the rate at which mortality increases with age and, therefore, the rate of senescence of the population.
