Abstract

Baram River Frog (Pulchrana baramica) is a ranid species distributed in the Malay Peninsula, Borneo, Sumatra and represents the sole species from the genus Pulchrana on Java Island. Cryptic species are commonly encountered within the amphibian group which can cause confusion in the identification process. Due to the broad distribution range of P. baramica and the frequent occurrence of cryptic species within the amphibian group, it is important to evaluate the taxonomic status of P. baramica. Therefore, we investigated the taxonomic position of P. baramica from three populations (Kalimantan, Sumatra, and Java) and identified the interpopulation genetic variation based on molecular data of the 16S mitochondrial gene. We reconstructed phylogenetic relationships using Neighbour Joining, Maximum Likelihood, and Bayesian Inference. The research results revealed that Pulchrana baramica is a monophyletic group and nested within a group together with P. glandulosa and P. laterimaculata. The monophyletic group of P. baramica consisted of four distinct lineages that molecularly showed interspecific genetic variation. Clade 1 represents the population of Sumatra and Borneo (Kalimantan), clade 2 comprises the population from Borneo (Sarawak), clade 3 consists of population from Java, and clade 4 represents the population from Sumatra. Further research is required with the addition of morphological and acoustic data as supportive evidence to obtain more extensive comprehension of species identification.

Abstract

River is one of the habitats for reptiles. Based on the research along Code River, Opak River and Gadjahwong River, reptiles commonly found along rivers in Yogyakarta were lizards and snakes. Research on lizards and snakes’ diversity is essential to know its diversity and to understand its habitat along rivers in Yogyakarta. Methods used was Visual Encounter Survey combined with time search. Data analyzed using Shannon-Wiener Index, Pielou Evenness Index and degree of abundance based on Buden (2000). Result obtained were lizards 9 species and 15 snakes’ species. Lizard diversity based on Shannon-Wiener Index, on upstream, midstream and downstream were categorized as low with H’ 0,246; 0,228 and 0,185 respectively. Snake diversity based on Shannon-Wiener Index, on upstream was low with H’: 0,099; on midstream and downstream were moderate with H’: 0,182 and 0,135. Lizard evenness based on Pielou Index, on upstream, midstream and downstream were categorized as low with E 0,178; 0,127 and 0,115 respectively. Snake evenness based on Pielou Index, on upstream, midstream and downstream were also categorized as low with E 0,099; 0,182 and 0,135 respectively. Most abundant lizards were: Eutropis multifasciata and Bronchocela jubata, meanwhile most abundant snakes were: Dendrelaphis pictus, Ahaetulla prasina, and Homalopsis buccata.
