为了资源的更新而竞争的物种服从与最小化某二次型条件相等的联立微分方程。从这个意义上说，竞争的作用是选择物种丰度，使其在一个表达式中具有最佳的最小二乘拟合[公式：见文本]。因此，能够竞争共存的物种的数量主要受种间竞争系数不平等的限制，而不受其大小的明显限制。季节性和资源数量成为限制共存物种数量的主要因素。
Species competing exclusively for renewing resources are shown to obey simultaneous differential equations equivalent to the conditions for minimizing a certain quadratic form. In this sense competition acts to select species abundances giving the best least-squares fit in an expression [Formula: see text] Thus the number of species which can coexist competitively is limited mostly by the inequality of the interspecies competition coefficients and not appreciably by their magnitude. Seasonality and number of resources become the main factors limiting the number of coexisting species.
