Abstract

ABSTRACTThe Sumatran rhinoceros is one of the most critically endangered species of large mammals due to habitat loss, fragmentation and illegal hunting so that the population of this species drastically decreased. At present, reproductive problems with a limited population are also a threat and require an appropriate solution. Therefore, data on molecular genetic information is very important as a basis for conservation management in maintaining long-term persistence of this species. Phylogenetic analysis based on sequences of CO1, 12SrRNA, and Cytochrome b gen from mitochondrial DNA genomes using neighbor-joining and genetic distance matrix calculations with the Kimura 2-parameter model (K2P) were implemented in pairwise distance calculations in the Mega (Molecular Evolutionary Genetics Analysis) program version 6.05. The study results show the genetic distance of Sumatran Rhinos from Sumatra and Kalimantan respectively 0.2 ± 0.00%, 0.8 ± 0.4%, and 0%. These results were reconfirmed that the Sumatran Rhino species in Sumatra and Kalimantan were taxonomy is no different. The study of genetic diversity based on D-loop of mitochondrial DNA contained 5 haplotypes, namely haplotypes 1 and 2 originating from the island of Sumatra and haplotypes 3, 4, and 5 originating from the island of Borneo. The genetic distance between individuals in this study ranged from 2.54 ± 1.4%, haplotype diversity (Hd) was 0.8 ± 0.172, nucleotide diversity (Pi) was 0.02269, Fu?s Fs value was 2.523, and Tajima?s test was 0.69497. The positive value (Fu?s Fs and Tajima?s test) indicated low genetic diversity and population expansion in the Sumatran rhino. In the study using 10 microsatellite loci, where the average number of allel/loci in Kalimantan (1.68) was higher than in Sumatra (1.22). Data from this study show that genetic variation between Sumatran rhinoceros from Sumatra and Kalimantan can be used as a basis for alternative that the populations of Sumatra and Borneo be considered as a single management unit.  Keywords: Sumateran  Rhinoceros, Mitochondrial DNA, Microsatellite

Abstract

ABSTRACTThere are six species of cockatoos in Indonesia which are well known as exotic, smart, and they can be trained in a variety of attractions. Thus, many people want to keep those birds as pets. All of pets which have been kept by community should be evaluated from various aspects before being reintroduced to their natural habitat. The examination of sex and species of illegal cocktoos play as a key role for the reintroduction programme. Theobjective of this study was to evaluate the reliability and effectivity of evaluation technique of morphometric and molecular for reintroduction programme of cockatoos. We used the COI gene sequences from 68individuals of cockatoos from pet communities in and around Jakarta and four sequences from GenBank. The phylogenetic analysis used the neighbor-joining method, in which the genetic distance matrix calculations with Kimura 2-parameter models that are implemented on a pairwise distance calculation in the MEGA program version 6:05. The result of the genetic variation of the cockatoo species which shows intraspecific divergence was Cacatua alba (n=4)= 0%, C. galerita (Australia n=9)= 0.6%, C. galerita (Indonesia n=53)= 0.3%, C .goffiniana (n=3)= 0%, C. moluccensis (n=7)= 0.1%, and C. sulphurea (n=2)= 0.3%, with a range of 0-0.6%. The results indicate that the average of intraspecific of COI in the cockatoos community was 0.25±0.055%, and interspecific divergences ranged from 3.1 to 11.6%. The phylogenetic tree shows the monophyletic clade of cockatoo species in Indonesia. In addition, DNA barcode analysis and molecular sexing could correct the error and doubts the result of five individual species identification and two individual sexing identification of C.galerita by morphological identification. The results of morphological examanation base on body weight, body length and head-bill length of C. galerita triton were not significantly different (P?0,5). Finally, 19 individuals C. galerita triton and two individuals P. aterrimus were reintroduced to their natural habitat.Keywords: cockatoo, barcodes DNA, reintroduction

Abstract

Sumatran elephants (Elephas maximus sumatranus) is endemic of Asian elephants in Indonesia, an endangered animal andlisted on Appendix I of CITES. Therefore, information on the status and distribution of the population of Sumatranelephants, including the distribution of genetic diversity is necessary to facilitate the development of adequate conservationand management strategies. The purpose of this research was to use Amely gene to trace paternal lineage of Sumatranelephants based on Y chromosome variation. A total of 22 blood samples of male Sumatran elephants were collected inSumatra (Way Kambas , Seblat, Bentayan, Sugihan, dan Bukit Serelo Lahat). We amplified intronic regions of the Ylinkedgene (Amely) using published primer sequences (Amely-R2 and Amely-F2) and sequenced. Sequences generatedfrom this study, aligned with reference sequences available in the GenBank, namely Elephas maximus (AY823325.1),Loxodonta Africana (AY 823320.1; AY 823321.1), Loxodonta cyclotis (AY823322.1; AY8233223.1, AY 823324.1).Neighbour Joining tree of Sumatran elephants was performed using MEGA version 5.2.2. The analysis results of 22-maleSumatran elephants, indicating that no diversity (no variation) of the Y chromosome obtained among the population ofSumatran elephants. Sumatran and Asian elephants have the same haplotypes. Further results confirmed that the savannaelephants (Loxodonta africana ) and the forest elephants (Loxodonta cyclotis ) formed two (2) separate clades, which showstwo different species. Results obtained in this study may help to design future conservation programs for the species.Keywords: Sumatran elephant, Amely gene, Y chromosome, Genbank, haplotype

Abstract

The cytochrome c oxidase subunit I (COI) gene is a reprensentative of all the protein-coding genes of the mitochondrial DNA genome that has been widely used as an animal species identification tool. In this study, 86 sequences of DNA barcodes of members of the family Accipitridae in Indonesia including Nisaetus bartelsi, Nisaetus cirrhatus, Haliaeetus leucogaster, Spilornis cheela, Haliastur indus, and 11 sequences from Genbank were examined. Each species was confirmed through the Basic Local Alignment Search Tool (BLAST). The construction of phylogeny trees based on COI gene sequences was performed by the Neighbors-joining method where the calculation of the genetic distance matrix with the Kimura 2-parameter model was implemented in pairwise distance calculation in the Mega version 6.05 programe. The results of the analysis showed that the divergence within species ranged from 0 to 0.3% (0.13 ± 0.12%), between species ranged from 1.6 to 18.5% (12.8 ± 3.73%), between genera ranged from 13 to 18.6%, and the average in the Accipitridae Family was 11.8%. Therefore, it could form clusters in each species cohesively and clearly separated between the taxa analyzed.
