Speciation Mode | Synopsis | References |
---|---|---|
Point mutation | Speciation whereby each individual in the metacommunity has an equal probability of producing an offspring of a new species. Produces many rare species with lifetimes unrealistically short | Hubbell (2001) |
Random fission | Speciation occurs through a population randomly dividing into two distinct species. Produces species with lifetimes unrealistically long | Hubbell and Lake (2003), Hubbell (2005), Etienne and Haegeman (2011) |
Peripheral isolate | Divergence follows the isolation of populations. Newly arisen species have abundances drawn from a normal distribution | Hubbell and Lake (2003), Hubbell (2005) |
Generalized speciation | A generalized neutral community model incorporating numerous modes | Haegeman and Etienne (2009) |
Protracted speciation | Speciation is a gradual, drawn out process. Results in a new predicted metacommunity SAD (termed the “difference logseries”) | Rosindell et al. (2010) |
