Past and present genetic structure of the tropical rainforest palm Astrocaryum mexicanum: effects of anthropogenic fragmentation.

Abstract excerpt

To assess whether fragmentation of the lowland rainforest of Los Tuxtlas natural reserve has altered the genetic structure of understory palm Astrocaryum mexicanum, we analyzed populations from undisturbed forest and forest fragments. The questions that this study addressed were: Has habitat fragmentation reduced gene flow and within-population genetic variation (allele loss)? Has this process, in turn, increased...
