Abstract

Reptilia merupakan kelompok hewan darat pertama yang sepanjang hidupnya bernafas dengan paru-paru, bersisik, serta telurnya mempunyai cangkang. Terdapat tiga ordo Reptilia yang dapat ditemukan di Indonesia yaitu Crocodilia, Testudinata, dan Squamata. Ordo Squamata merupakan ordo terbesar yang terdiri dari 722 spesies di antaranya mencakup sub ordo Lacertilia dan terdiri atas famili Iguanidae, Agamidae, Varanidae, Scincidae, Chamelonidae, dan Gekkonidae. Tokek adalah nama umum untuk menyebut cicak besar atau spesies kadal dari anggota famili Gekkonidae yang secara sempit merujuk pada spesies dari anggota genus Gekko. Pola kemiripan antar spesies anggota genus Gekko di Indonesia perlu diketahui sehingga tujuan konservasinya semakin mudah dilaksanakan. Tujuan dari pengamatan ini adalah untuk mengetahui karakter morfologi anggota genus Gekko berdasarkan spesimen Museum Zoologicum Bogoriense Puslit Biologi-LIPI. Analisis data berdasarkan prosedur Similarity for Qualitative Data (SIMQUAL) yang selanjutnya dilakukan pengelompokkan Sequential Angglomerative, Hierarachial, and Nested (SAHN) dengan metode Unweighted Pair Group Method with Aritmethic Average (UPGMA) menggunakan program komputer Numerical Taxonomy and Multivariate Analysis System (NTSYSpc) 2.02 untuk menentukan kekerabatan antarspesies. Pengamatan dilakukan pada 24 sampe Gekko yang tergolong dalam 4 spesies berbeda, yaitu Gekko gecko, Gekko smithii, Gekko monarchus, dan Gekko vittatus dengan 14 karakter morfologi: Dorsal Tubercles (DTR), Gender (GD), Granulars on Throat (GOT), Nuchal Loop (NL), Post-Mental (PM), Precloacal Pores (PP), Precloacal-Femoral Pores (PFP), Rostral-Nostril (RN), Snout Vent Length 100 (SVL), Subcaudal Devided (SCD), Tail-Depressed (TDR), dan Tail Tubercles (TT). Hasil matriks kemiripan morfologi 4 spesies Gekko memiliki nilai koefisien fenotipik (Kf) tertinggi sejumlah 0,68 yang menandakan hubungan korelasi sedang. Empat spesies Gekko yang diamati membentuk 2 kelompok besar, yaitu kelompok I yang terdiri atas Gekko gecko, G. smithii, dan G. monarchus, sedangkan kelompok II hanya berisi G. vittatus; kelompok I dan II dibedakan berdasarkan karakter subcaudal not devided dan tidak adanya Y-pattern pada kelompok I.

Abstract

Two of the six Chirixalus species currently known are distributed in Indonesia. Both species are only known to be distributed in Java, and they are Chirixalus trilaksonoi and Chirixalus pantaiselatan. During two field expeditions conducted in 2022 in Palembang, South Sumatra, we encountered several individuals exhibiting morphological similarities to C. trilaksonoi. Subsequent analysis, encompassing molecular, morphological, and bioacoustic, was undertaken to ascertain the identity of these individuals. The analyses outcomes unequivocally confirm that the specimens from Palembang are indeed C. trilaksonoi. Nevertheless, slight variations were observed between the Javanese and Sumatran populations of C. trilaksonoi. These populations exhibited a low genetic distance of 0.6% in mitochondrial DNA and displayed three polymorphic sites. Furthermore, there are slight differences in various morphological characteristics, and in advertising calls. The IUCN red-list status of this species was also evaluated, and based on the available evidence, we propose C. trilaksonoi as Vulnerable according to criteria B1ab(iii). This study stresses the importance of comprehensive taxon studies, especially in neighboring island, and in one biogeographical region.

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

Morphological variations in species with a relatively broad distribution, including the genus Tytthosincus, were likely a result of island isolation. This research was conducted to map the morphological variations of the genus Tytthoscincus in Indonesia. A total of 32 specimens of the Tytthoscincus scientific collection in the Zoologicum Bogoriense Museum (MZB) - National Research and Innovation Agency (BRIN) and identified as T. temmincki, T. textus, and T. parvus have been examined and data collection which includes six morphometric characters and 12 meristic characters. Morphometric data were analyzed in univariate and multivariate. Univariate analysis was carried out by the Kruskal-Wallis test, while multivariate analysis was done with the Principal Component Analysis (PCA) test. The results showed morphology in T. temmincki and T. textus, namely the number of loreal scales and tympanum diameter. Both T. temmincki and T. textus consist of two groups, but the morphological variation in T. temmincki and T. textus in this study has yet to provide certainty as a different species. However, one was T. textus Type 2, isolated from other species on Jampea Island, Sulawesi. Further research was needed to clarify the taxonomic status of these variations by increasing the number of adequate samples supported by the molecular analysis approach. Keywords: meristic, morphometric, species, Tytthoscincus, variation.
