New Size Measurements in Population Ecology

Abstract

In organizational ecology, the analysis of the impact of competition between populations on vital ratios is relatively underdeveloped. This paper addresses this issue by developing new competition measurements that focus on the importance of organizational size. The application of these measurements in the case of competition between organizational subforms in a population, and their impact on mortality rates, demonstrate their usefulness for modelling competition. Specifically, the results show how levels of competition between firms in a population can be more clearly analysed when the rival population mass or concentration indices are used.
