A computer simulation was used to investigate the relative effects of changes in net fecundity and development time on population growth rate (r). Increases in net fecundity had the largest effect on r when net fecundity is small. Conversely, decreases in developmental time had the largest effect on r when net fecundity was large. The intersection point where similar changes in developmental time, and net fecundity had equivalent effects on r was also investigated in four organisms with very different life histories. Cases were considered where changes in net fecundity and developmental time are correlated and different results were obtained.
使用计算机模拟来研究净繁殖力和发育时间的变化对种群增长率（r）的相对影响。当净繁殖力较小时，净繁殖力的增加对r的影响最大。相反，当净繁殖力较大时，发育时间的减少对r的影响最大。还在四种具有非常不同生活史的生物体中研究了发育时间和净繁殖力的类似变化对r具有等效影响的交点。考虑了净繁殖力和发育时间的变化相关的情况，并获得了不同的结果。
