Abstract
Using the ratios of successive densities of an increasing insect population, Morris (1963a, b) fitted a straight line to the points in the plot of log Nt+1 versus log Nt, and used its slope as an index of density—dependence. Salt (1966) applied the method to protozoan populations, and also demonstrated that the points so plotted may fit a shallow curve rather than a straight line. He used the ratio between the slopes at the beginning and end of the curve as an index of density—dependence. This ratio is however an index of change in density—dependence rather than a measure of its intensity. The implications and treatment of such changes in slope are discussed.This publication has 0 references indexed in Scilit:
