Ancient polymorphism within hylarana signata (amphibia: anura: Ranidae) lineages of west (peninsular) and east (Sarawak, Borneo) Malaysia
The Hylarana signata group in Malaysia, as currently construed, comprises two species- Hylarana signata and H. picturata. Both are similar in morphology and habits, but differ in colouration (chiefly, the presence or absence of a dorsolateral line). It has been suggested recently that Malaysian...

| description | The Hylarana signata group in Malaysia, as currently construed,
comprises two species- Hylarana signata and H. picturata. Both are similar
in morphology and habits, but differ in colouration (chiefly, the presence or
absence of a dorsolateral line). It has been suggested recently that Malaysian
H. signata (from both Peninsular and Borneo) is different from H. signata of
Philippines and may be non-conspecific, also from what is currently referred
to this taxon on Malaysian Borneo. Specimens of the Hylarana signata group
were sequenced to detect genetic variation among species and to confirm the
existence of cryptic species, via 16S rRNA gene. Seven study sites in Sarawak
were chosen for data collection, namely four National Parks (Matang/Matang,
Bako, Mulu and Similajau), and three unprotected areas (Borneo Heights,
Sadong Jaya and Bario). Data from Tasik Chini, Pahang, West (Peninsular)
Malaysia were included in our molecular analysis, to infer relationships
within the species group. PCR amplification and direct sequencing of partial
16S rRNA mitochondrial DNA was used to infer the phylogeny presented. The
study revealed phylogenetic complexity within Malaysia Hylarana signata
group due to the occurrence of cryptic species or ancient polymorphism of the
lineages. The results obtained underscore the need for a complete sequence of
DNA regions or multigenes of the same rate of evolution in order to elucidate
the phylogenetic relationship in the group through more extensive samplings
spanning wider geographical ranges. |
