Inferências filogeográficas e estruturação populacional de Sturnira lilium (Phyllostomidae) da Mata Atlântica

Abstract

Bats species exhibit degrees of genetic structure because they have a high potential for dispersal.Some scientist proposed that bats species with a continental distribution report low levels of genetic divergence and not much geographical structure. However, others researches shown that some bats species has high level of sequence divergence between geographical distances individuals. Sturnira liliumwas characterized as a bat specie that presents low levels of sequence divergence within shared haplotypes and little geographic structure of the mtDNA clades. The objective of this study were to describe and analyze the possible geographical structure for genes lineages of Sturnira liliumpopulations; analyze intra and inter-population genetic diversity from Sturnira liliumin Atlantic rain forest and infer phylogenetics relation between the used samples. For this we used mitochondrial DNA gene cytochrome b. Either the phylogenetics analyses as the genetic population analyses indicate the same thing: S.lilium populations do not shown an evident geographical structure inside brazilian Atlantic rain forest., do not have isolated populations ( high values of Nm and low values of Fst) and S.liliumpopulations maybe under a rapid expansion (stralike phylogeny and negative significant Tajima"s D and Fu Fs). The higher levels of sequence divergence between the two clades pointed by phylogenetics analyses and the fact that this divergence aren"t related with geographical structure guide us to question if brazilian Atlantic rain forest S.liliummight represents a home range expansion for the subspecie Sturnira lilium pavidensor if this divergence indicated Sturnira liliumas a criptical species complex
