Table 2.
Ecological scenario | Dispersal frequency | Among-habitat dispersal | Importance of dispersal in mating system evolution |
---|---|---|---|
Island/continent (or exotic invader) | Rare | Highly asymmetric | Little |
Range limits | Regular | Asymmetric | Middle |
Metapopulation dynamics (e.g. weeds) | Regular | Symmetric | High |
As a consequence of heterogeneous among-habitat dispersal, the heterogeneity of pollination environment is expected to influence more or less the outcome of mating system evolution.
