Age estimation for the ten largest clones of Zostera noltei assuming no asexual hydrochory.

N–number of clonemates sampled; distance–maximum distance sampled between two clonemates; O1 through O4 –shortest distance to the estimated point of origin; t0 through t3 –estimated age of the clone assuming rhizome elongation from the point of origin at different sea levels (APPENDIX A); Data is also shown for one clone of the seagrass Cymodocea nodosa in the Ria Formosa lagoon (reanalyzed from Alberto et al. 2008).
