Abstract

Cuscus is marsupial’s animal (Phalageridae) which has limited spread in eastern Indonesia (Sulawesi,Maluku, Papua), Australia and Papua New Guinea. The ex-situ and in-situ conservation of cuscus undercaptivating condition is an alternative solution to protect cuscus from extinction. This study aimed todetermine nucleotide sequence and genetic markers on 12Sr RNA gene with sequencing method of eachspecies on three islands. Whole genome DNA was extracted from 17 samples of cuscus obtained fromdifferent habitats, Sulawesi (2 individual), Maluku (7 individual), and Papua (8 individual) according tothe protocol of Qiamp DNA Blood Mini Kit (Qiagen), and then it was used as template for amplificationof 12Sr RNA gene by using PCR. PCR product were then purified using column chromatography and wereused as template for sequencing reaction. Result sequencing of 12Sr RNA gene were analyzed usingMEGA program version 6. PCR product gives a result nucleotida of 958 bp according to databasegenebank, sequencing product gives result nucleotida of 896 bp and found of 105 different nucleotide sites.Filogram based on nucleotide sequences 12SrRNA gene from Sulawesi cuscus is Ailurops ursinus whereasthe cuscus from Papua and Maluku is Phalanger sp. and Spilocuscus maculatus species. Thirteen nucleotidasites were found, sites no 67 (A/G), 89 (G/C), 137 (T/C), 285 (G/A), 468 (T/C), 595 (T/C, 598 (T/C), 647 (T/C),654 (G/A), 665 (T/C), 769 (C/T), 874 (C/T), and 876 (A/G) which can be used as genetic marker betweenPhalanger genera from Papua and Maluku, and three nucleotida sites (sites no 127 (G/A), 481 (C/T), and885 (T/C) can be used as genetic marker between Spilocuscus genera from Papua and Maluku.

Abstract

Bottlenose dolphins (Tursiops sp.) is one of the aquatic mammals widely spread in the marines ofIndonesia archipelago, especially the Java Sea. The taxonomy of the genus Tursiops is still  controversial.The purpose of this study was to examine the molecular basis of Tursiops sp of Java sea marine origin onthe basis of its NADH dehydrogenase gene subunit 6 (ND6) sequences. Samples of blood were collectedfrom five male bottle nose dolphins from captivity of PT. Wersut Seguni Indonesia. DNA was isolated,amplified by polymerase chain reaction (PCR), sequenced, and analyzed the data using the MEGA v. 5.1program. The results of PCR amplification was 868 base pairs (bp), DNA sequencing showed that 528nucleotides were ND6 gene, nucleotide at the position of 387 could be used to distinguish the bottle nosedolphins Java marine origin with T. aduncus.   Filogram using Neighbor joining method based on thenucleotide sequence of the gene ND6, showed that bottle nose dolphins Java marine origin belong to groupof T. aduncus.

Abstract

In a conservation effort, the identification of Tarsier species, on the bases of the morphological andmolecular characteristic is necessary. Up to now, the identification of the animals were based on themorphology and vocalizations, which is extremely difficult to identify each, tarsier species. The objective ofthis research was to study the genetic diversity on ATP6 gene of Tarsius sp. Based on sequencing of PCRproduct using primer ATP6F and ATP6R with 681 nts. PCR product. The sequence of ATP6 fragmentswere aligned with other primates from Gene bank with aid of software Clustal W, and were analyzed usingMEGA program version 4.0. Three different nucleotide sites were found (nucleotide no. 288, 321 and 367).The genetic distance based on nucleotide ATP6 sequence calculated using Kimura 2-parameter modelindicated that the smallest genetic distance 0%, biggest 0.8% and average 0, 2%. The phylogenetic treeusing neighbor joining method based on the sequence of nucleotide ATP6 gene could not be used todifferentiate among T. Dianae (from Central Sulawesi), T. Spectrum (from North Sulawesi), T. bancanus(from lampung, South Sumatera) and T.bancanus from West Kalimantan.

Abstract

In conservation, identification of tarsier species based on morphological and molecular characters isrequired. However, to date the identification of animals is simply based on their morphological characterand vocalizations, while in fact it is difficult to identify each species of Tarsius sp morphologicaly.  Thepurpose of this study is to obtain genetic markers that can be used to identify Tarsius sp on ND6 mitochondrialgenes and reveal affiliations and phylogenetic relationships Tarsius sp. with other members of primates.Samples were obtained from several original habitats of Tarsius sp. Three samples were taken from NorthSulawesi, one sample was collected from Central Sulawesi, three samples from Kalimantan  and threesamples from South Sumatra. The isolated DNA is then used as a template for amplification of DNAfragments by PCR. Amplicon (PCR product) obtained 566 bp and 629 bp. Nucleotide sequencing resultsshows 513 nucleotides, the smallest genetic distances of 0%, the highest of 30.2% and average of 16.3%.Nucleotide and amino acid sequences of ND6 can be used as genetic markers to differenciate T. spectrum,T. dianae and  T. bancanus but they fail to function as genetic markers to distinguish  T. bancanus ofKalimantan and Sumatra origin.
