Phylogeny and phylogeography of Barbonymus schwanenfeldii (Cyprinidae) from Malaysia inferred using partial cytochrome b mtDNA gene

A study on the genetic variation of Barbonymus schwanenfeldii (Bleeker) populations from Malaysia was done using partial sequencing of cytochrome b mtDNA gene. Samples were collected from various localities in Peninsular Malaysia, Sarawak and Sabah, including the Indonesian (Kalimantan) type of B. s...
