Optimal Timing of Reproduction: Late Breeding Wins in Competition

This paper's main proof relies on the classic Lotka-Volterra competition model, describing the competitive relationship between two species. Each species' growth rate is determined by its own population density and the other species' density.

The authors use this model to study competition between two species with contrasting reproductive strategies: one breeds early, the other late. They found that in the absence of competition, early breeders have higher reproductive value. However, when the two species compete, late breeders are more likely to win the competition.

Further proof shows that as competition intensity increases, late breeders' fitness increases faster. This is because they can avoid competition in intense environments, whereas early breeders are more susceptible.

Therefore, the authors conclude that late breeders have a more optimal reproductive strategy, enabling them to better adapt to competitive environments. This conclusion has wide applications in ecology, aiding in understanding species competition and its impact on ecosystems.
