Abstract

This article sought to assess the genetic diversity within and between natural populations of Astrocaryum acaule
by means of AFLP markers. Ninety individuals were sampled in three populations located in Manaus (state of
Amazonas) across regions with different intensities of anthropogenic activity. Two clusters were differentiated
by means of dendrograms and Bayesian cluster analysis, the first consisting of individuals from the Tarumã-Açu
population in an intensely agricultural region, and the second, of populations from UFAM and Tupé conservation
areas. The physical isolation of A. acaule populations has resulted in good conservation of its genetic identity, since
anthropogenic activity is an important modifier of the genetic diversity of natural populations. Genetic diversity was
higher within populations (74.58%) than between them (25.42%), which means that we have to collect representative
samples from each of the genetically distinct groups for genetic conservation of the species. Therefore, in situ
conservation is recommended.
