Moreover, considering that the samples collected in this study provide a snapshot of the species' distribution area as a whole in Northeastern Brazil and that the genetic differentiation detected is low, *ex situ* conservation should be considered in conservation strategies these bromeliads. Despite the possibility of *ex situ* conservation, *in situ* conservation must be considered as a priority. More extensive studies must be carried out to delineate areas protected by law that effectively help to preserve these species. Furthermore, the potential of the ISSR and SSR markers in studies of population structuring in *A. fulgens* was also demonstrated, this possibly constituting a useful aid in the studies of other bromeliads species.
