摘要

Studies on population genetic differentiation are essential for understanding the ecological, biological, and behavioral aspects of species, as well as their diversification patterns and how populations evolve over time. The species Artibeus planirostris, one of the best-known Neotropical fruit bats, has a wide distribution. This species exhibits high dietary plasticity and plays a significant ecological role. While A. planirostris has been used as a model organism in various studies, no comprehensive research has yet explored its population dynamics. Here, we analyzed fragments of the mitochondrial Cytochrome b (Cyt b) and Cytochrome c Oxidase 1 (COI) genes to investigate the genetic diversity, population structure and demographic history of A. planirostris in the Neotropics. Our findings reveal a weakly structured geographic population pattern. Nevertheless, in peripheral populations, we have observed limited maternal gene flow due to isolation by distance or potentially geographic barriers. It suggests that local adaptations, shaped by specific environmental pressures and Pleistocene climatic fluctuations, may have influenced the dispersal and colonization abilities of A. planirostris in these regions. The demographic history of A. planirostris indicates a recent population expansion during the late Pleistocene, approximately 50,000–60,000 years ago.
