| description | A study on phylogeny of eight species of babblers (Family: Timaliidae) in Sarawak by using mitochondrial
DNA (mtDNA) cytochrome oxidase I (COI) gene was conducted. The samples were taken from both fresh
and also voucher specimens that were available in UNIMAS. Four phylogenetic trees were constructed by
using four different methods namely, Neighbour-Joining (NJ), Maximum Parsimony (MP), Maximum
Likelihood (ML) and Bayesian inferences in this study. The ML and Bayesian trees showed that Timaliidae
can be grouped into two groups that is group 1, genus Stachyris, and group 2, which consist of Pellorneum,
Trichastoma, Malacocincla and Malacopteron genera. This showed that Pellorneum, Trichastoma,
Malacocincla and Malacopteron are closely related compared to genus Stachyris. COI is a good genetic
marker which can detect intraspecific variation within species and the relationship of the individuals by
comparing the genetic divergence and the length of tree. |
