On population aspects of group disasters: an evolutionary view.
Simple mathematical models were constructed (using a DEC PDP 11/40 computer) to evaluate the probable significance of differences between individuals in adaptive reserve--survival time (modelled as "failure rate")--for group survival and of basic population parameters (fertility and mortality) for the gradual compensation of group size/age distribution of a population after an acute group disaster. The results indicate that reversion to prehuman biological regulative mechanisms probably occurs, and that after short-lasting group disasters the time-course for compensation (normalization) of population size and age distribution (when probable values of fertility and mortality were considered) is prolonged.
