Abstract excerpt

Astyanax bimaculatus are small characids known as piabas or lambaris that form a complex encompassing 18 species, including cryptic species. The present study aimed to use DNA barcode to analyze populations of A. bimaculatus found in Maranhão hydrographic basins, comparing molecular diversity indices between populations from the other Brazilian basins. The results revealed the formation of 32 haplotypes (h =...
