Neutral ecological theory comes in two flavors-a two-stage model with space implicit and a spatially explicit version. Reconciliation of the two flavors has proven problematic. Panmixis, an implicit assumption of the two-stage model, is neither realistic for nor supported by tropical forest trees. However, in spatially explicit versions, stochastic species input in local communities is still necessary to retain high species richness. A unified theory of biodiversity must include both stochasticity and relevant ecological mechanisms.
