| Abstract | This paper presents simulation results of a spatially explicit, individual based, discrete state model of two species competing for growth sites. An organism's survival and reproduction usually depend on interactions with nearby individuals. Predicting how these local processes influence population levels and community-level patterns requires spatially explicit models. In environments disturbed by high birth and death rates, an inferior species could invade and coexist with a superior species. A larger interaction neighborhood decreased coexistence when species differed in dispersal rate, but increased coexistence when competitors differed in mortality rate. In an environment with low birth and death rates, the inferior species was generally excluded, but larger interaction neighborhoods increased the probability of coexistence. |
