New Guinea singing dogs (NGSD) are identifiable by their namesake vocalizations, which are unlike any other canid population. Their novel behaviors and potential singular origin during dog domestication make them an attractive, but elusive, subject for evolutionary and conservation study. Although once plentiful on the island of New Guinea (NG), they were presumed to currently exist only in captivity. This conclusion was based on the lack of sightings in the lowlands of the island and the concurrent expansion of European- and Asian-derived dogs. We have analyzed the first nuclear genomes from a canid population discovered during a recent expedition to the highlands of NG. The extreme altitude (>4,000 m) of the highland wild dogs’ (HWD) observed range and confirmed vocalizations indicate their potential to be a wild NGSD population. Comparison of single-nucleotide polymorphism genotypes shows strong similarity between HWD and the homogeneous captive NGSD, with the HWD showing significantly higher genetic diversity. Admixture analyses and estimation of shared haplotypes with phylogenetically diverse populations also indicates the HWD is a novel population within the distinct evolutionary lineage of Oceanic canids. Taken together, these data indicate the HWD possesses a distinct potential to aid in the conservation of NGSD both in the wild and under human care.

Thermophilic bacteria are bacteria that are able to survive in environmental conditions with high temperatures. Thermophilic bacteria are one of the important sources of thermostable enzymes that can be isolated from geothermal environments such as hot springs with temperatures ranging from 50–80 oC. Aims of the study to isolate and identify local isolates of thermophilic bacteria from hot springs in Moso Muara Tami District, Papua. The results showed that 7 isolates (A1, A2, A3, A4, B1, B2, and B3) that were isolated and identified based on phenotypic characters were included in the genus Bacillus. Key words: Thermophilic, characterization, isolation, identification, phenotypic.
Daun gatal (Laportea aestuans) is an indigenous plant of Papua hich has been widely used for pain relief as traditional medication in the local community. The leaves were just picked then treated to cure for painful body. This treatment are giving itchy sense as an indication that medication is working on the body as local people assumed. The aim of the study was to determine the activity of antibacteria of daun gatal against Escherichia coli, Staphylococcus aureus and Salmonella typhi. Samples of daun gatal were collected from Biak Numfor Papua. The methods are started with filtering of daun gatal using 100 mash and extracted with ethanol. Extract was made in 250, 500, 750, 1000 ppm, with chloramphenicol as a control positive, while the test of antibacterial activity was done by disc diffusion method. The results showed that daun gatal has antibacterial activity against E. coli, S. aureus and S. typhi. Daun gatal extract (L. aestuans) is effective in inhibiting the growth of bacterias with zone inhibition of 1000 ppm extracts which were 8.55 mm (E. coli), 9.02 mm (S. typhi), dan 9.37 mm (S. aureus). Key words: Antibacteria, E. coli, L. aestuans, S. aureus and S. typhi.
Conservation effort and knowledge on coral reef ecosystem are necessary to protect marine ecosystem. Coral reef ecosystem is very important to support marine biota especially fishes and benthos. The presence of coral reef indirectly support local people income, therefore is is necessary to conserve coral reef ecosystem. District of South Waigeo is one of tourist area as well as preserve area in Raja Ampat Regency of Papua Barat Province. The aim of this study is to identify the current condition of coral reef in Saporken Village of South waigeo District. Data were collected by survey method using coral reefs Point intercept transect method, observation and interviews to determine the social, economic and cultural impact., and measures taken to manage coral reef management in village Saporkren Marine Protected Areas. The results showed that knowledge Saporkren Village community, the conservation community knows about how destructive such arrests are not carried out the bombing, while the traditional way people work is local wisdom. Condition of coral cover in the village of Marine Protected Areas Saporkren in good condition (live coral cover=51%) and very good water quality, flow velocity at high tide ranged from 4.25 to 22.3 cm/sec and the flow velocity at low tide over small ranging from 5.07 to 19.60 cm/sec, salinity ranged from 32–35‰ and wave height ranged from 0.75 m. Based on the results of this study concluded that: Village community know Saporkren conservation activities of local government programs, and the traditional way to preserve coral reef still implemented.Key words: Conservation, coral reefs, Saporkren village, Raja Ampat.
