| Abstract | dc.description.abstract | The effect of colonization on the distribution of genetic diversity within and among populations in relation to species characteristics
remains an open empirical question. The objective of this study was to contrast genetic diversity within and among established
and colonizing populations of Nassauvia lagascae var. lanata on Volc á n Lonquimay (Araucan í a Region, Chile), which
erupted on 25 December 1988, and relate genetic diversity to biological characteristics of the populations. We analyzed a total of
240 individuals from 15 populations distributed along the Andes Cordillera using AFLP and obtained a total of 307 AFLP bands,
of which 97.7% are polymorphic. Values of population differentiation ( F ST ) did not differ signifi cantly among established and
colonizing populations, but colonizing populations did have reduced levels of genetic divergence (as indicated by private and rare
bands) and genetic variation (e.g., Shannon index). We conclude that a founder effect through limited numbers of founding
propagules derived from nearby source populations has not yet been compensated for by subsequent population growth and migration.
Low rates of secondary dispersal via running water, kin-structure within populations, and slow population growth seem to
contribute to the slow recovery of genetic diversity. | en_US |
