使用莱斯利矩阵和类似种群模型进行的蒙特卡罗模拟表明，随着存活率或繁殖力方差的增加，预期种群增长率会下降。这是由于詹森的不等式，他观察到增长率是特定年龄存活率和生育率的凹函数。建议将此观察结果应用于人口统计研究、种群模拟、最佳收获策略以及针对生育率和存活率差异的自然选择。
Monte Carlo simulations with the Leslie matrix and similar population models show that as variance in survivorship or fecundity increases, expected population growth rate decreases. This is attributed to Jensen''s inequality with the observation that rate of increase is a concave function of age-specific survivorship and fertility rates. Applications of this observation are advised for demographic studies, population simulation, optimal harvest strategies and natural selection for variance in fertility and survivorship rates.
