| Zusammenfassung: | Rain forests exhibit enormous species diversity, but the mechanisms for establishing and maintaining such diversity are unknown. Models involving both exploitative and pre-emptive competition have been proposed. We examine two of these models mathematically and show that neither can exhibit species diversity. The inclusion of random fruiting events, together with seedling population decay, can result in both models exhibiting long-term coexistence of many species. However, the parameter values required |
