| Summary: | Studies have shown that some characters, such as morphological, biochemical and behavioural characteristics were
shared among con-specifics of closely related frog species. It is hypothesized that closely related frogs would have similar
vocal apparatus structure to produce similar call characteristics, in order to be recognized by con-specifics. The vocal
apparatus structures of the frogs from Ranidae were, thus, investigated and calls were recorded from various locations
in Sarawak, Borneo. The vocal apparatus was sliced and stained using haematoxylin and eosin staining method. The
prepared slides were scanned using Dotslide System Olympus BX51. Captured images were further measured using
Microscope Olympus BX51. The results showed that the vocal apparatus structure of ranids in Sarawak differed in length
between pulvinar vocale and posterior margin (pvpm) or known as vocal cord stricter. This character was deemed to
be the most significant character to discriminate the Sarawak ranids. It is suggested that histological analysis is also a
good method for study of phenotypic variation of frog species, as shown by the vocal apparatus structure of the anurans.
This study provides an alternative method to differentiate taxonomic identity among frog species. |
