Seeds collected from parents that flowered at different times were dispersed onto experimental plots at different times during the normal dispersal season. Parental flowering and dispersal times, which are correlated with each other, independently affected offspring germination, growth, and time of reproduction. Estimated population growth rates were highest for offspring that were dispersed early in the dispersal season and that came from early flowering parents. The data provide evidence that 1) an individual's fate is determined by the environment of the previous generation, and that 2) an individual's fitness should be calculated from life history data that span more than one generation.
从在不同时间开花的亲本收集的种子，在正常传播季节的不同时间被播撒到实验地块上。亲本的开花时间和传播时间相互关联，它们各自独立地影响子代的萌发、生长和繁殖时间。对于在传播季节早期传播且来自早开花亲本的子代，估计的种群增长率最高。这些数据提供了以下证据：1）个体的命运由上一代的环境决定；2）个体的适合度应根据跨越不止一代的生活史数据来计算。
