Abstract: Possibility of a coexistence of different species is one of the important issues in ecology. Various mechanism and methods have been proposed to describe biodiversity. In this paper we present and discuss a new model describing the tolerance-fecundity trade-off on a homogeneous habitat, as a mechanisms for sustaining biodiversity. The model is investigated using two techniques – difference equations operating on globally defined functions and computer simulations dealing with individual plants. We show that while the first approach excludes the possibility of a coexistence of species, the second method allows it. We argue that it is the individual treatment of each plant life history which allows for coexistence, while operating on a whole population denies such a possibility.
