Abstract

Recent analysis of a simple population model with Darwinian evolution found conditions under which semelparity (a single reproductive event at the end of an organism's life) or iteroparity (multiple reproductive events over a lifetime) evolve in a population when the trade-off between reproduction and survival is linear. Additionally, previous works using different mathematical techniques show that the concavity of the trade-off relationship can alter the expected life history strategies. Thus, we developed a model and found that the concavity of the reproduction-survival curve can still have a large impact on life history strategies in an ecological model with Darwinian evolution.
