Longitudinal analysis of Plantago: adaptive benefits of iteroparity in a short-lived, herbaceous perennial

Longitudinal analysis of Plantago: adaptive benefits of iteroparity in a short-lived, herbaceous perennial

Ecology 91(2): 441-447

Theory suggests that iteroparity may confer greater fitness than semelparity in situations in which temporal environmental variation is high and unpredictable. Variable age-specific mortality, density dependence, and other factors may also favor iteroparity over semelparity. Here, we empirically test the adaptive benefits of greater numbers of reproductive years in a study of reproductive schedules in an experimental population of a short-lived polycarpic perennial, <i>Plantago lanceolata</i>.
