Abstract
A simple model of competition among individuals for space is defined and analyzed. Each individual is assumed to occupy a certain area and grow at a specified rate. When two individuals attempt to occupy the same area, one or the other dies. An analytic approximation for the model is developed and tested against computer simulations. The implications of the model for the self—thinning of even—aged stands, for the generation of overdispersed spatial patterns, and for the generation of bimodal size distributions are discussed.

Journal of EcologyCompetition and Stand Structure in Some Even-Aged Plant Monocultures
425 Citations1975E. David Ford
Work on competition in monocultures has concentrated on studies of population structures or on changes in individual plant characteristics observed under conditions where competition is thought to take place; it is the assumed outcome of competition which is studied.
Journal of Theoretical BiologyThe allometric interpretation of the self-thinning rule
326 Citations1981James F. White
An attempt to reformulate the self-thinning rule, based on the traditional allometric derivation, is shown to be unsatisfactory and an alternative allometry derivation is presented.

224 Citations1960E. C. Pielou
In studying aggregated plant populations allowance for the effects of plant size appears to have been made only by Skellam (1952) who calculated a distribution based on the assumption that clumps of plants occurred at random but within a clump the individuals exhibited a positive binomial distribution owing to the effectsof competition.
Annals of BotanyA Model for Growth and Self-thinning in Even-aged Monocultures of Plants
114 Citations1980D. P. Aikman, Andrew R. Watkinson
A theoretical model is derived from simple postulates to describe the rates of growth and mortality of plants in populations of different densities and exhibits characteristics that appear realistic upon comparison with published data.
EcologyNearest Neighbor Assessments of Spatial Confirgurations of Circles rather Than Points
91 Citations1979Daniel Simberloff
Analysis of nearest neighbor analysis for circles finds that distortion may be sufficient to lead to incorrect conclusions, such as regularity for an arrangement which is, in fact, clumped.

62 Citations1979Deborah Rabinowitz
The distribution of seedling weight in even-aged stands of Festuca paradoxa, a native North American prairie grass, is studied, and it is reported that though bimodality may be an eventual outcome of interference, it cannot be used as a measure of the strength of interaction between individuals.
Journal of Theoretical BiologyBimodality in even-aged plant monocultures
58 Citations1978D. J. Gates
A model of competition between plants or forest crops by mutual shading leads to bimodality in the frequency distributions of plant dimensions in agreement with the recent experimental study by Ford.
