Speciation with gene flow between two Neotropical sympatric species (Pitcairnia spp.: Bromeliaceae).

ABSTRACT: The study of mechanisms that generate new species is considered fundamental for broad areas of ecology and evolution. Speciation is a continuous process in which reproductive isolation is established, and it is of fundamental importance to understand the origins of the adaptations that contribute to this process. Hybrid zones are considered natural laboratories for the study of speciation and represent ideal systems for such studies. Here, we investigated genomic differentiation between hybridizing Neotropical species Pitcairnia staminea (G. Lodd.) and P. albiflos (Herb.). Using thousands of SNPs genotyped through RAD-seq, we estimate effective population sizes, interspecific gene flow, as well as time of divergence between these two sister species and identify candidate geno
