Other claims from this paper (5)
- Observation Of 307 AFLP bands, 97.7% were polymorphic.
- Observation Population differentiation did not differ significantly between established and colonizing populations.
- Observation Colonizing populations had reduced genetic divergence indicated by private and rare bands.
- Mechanism A founder effect from limited nearby founding propagules had not been offset by later growth and migration.
- Mechanism Low secondary dispersal, within-population kin structure, and slow growth appeared to contribute to slow genetic diversity recovery.
