Java slow loris

Java slow loris
Slow loris-sometimes also referred to shy-is kind of slow-moving primate. Hair color varies from whitish-gray, brown, to blackish. On the back there is a brown line across the back until your forehead, then branched into the ear and eye base. 0.375 to 0.9 kg body weight, adult body length 19-30 cm.

In Indonesia, this species can be found in Sumatra, Java and Kalimantan. Slow Loris (Nycticebus coucang) is a kind of primate are cute and adorable, so no wonder many of the general public which makes this primate to be used as a target for pets.

The slow loris family are often cited shy, consists of eight genera (genus) and subdivided into 14 species. The distribution is quite broad, ranging from Africa south of the Sahara, India, Sri Lanka, South Asia, East Asia and Southeast Asia. From 8 genus, in Indonesia only found a clan, namely Nycticebus.

Nycticebus clan consists of five types, namely:
Nycticebus coucang spread in the Malay Peninsula, Sumatra and surrounding islands.
Nycticebus pygmaeus in Indochina, Laos and Cambodia.
Nycticebus bengalensis in India to Thailand.
Nycticebus javanicus, only found in Java.
Nycticebus menagensis, only found in Borneo and surrounding islands.

Slow loris is a primate that lived in Indonesia's tropical forests, like the primary and secondary forests, shrubs and bamboo groves. Slow loris spread in Southeast Asia. In Indonesia lemurs are found in Sumatra, Kalimantan and Java. However, until now there is no definite and accurate data about the number of population in the wild. However, the shrinkage of the lemur habitat and the rampant poaching and illegal trade can be used as an indicator that the decline in the wild.

Based on the results of research conducted by Javan Slow Loris Conservation Project (2006) from University of Indonesia it is known that the population in the forests TNGGP is as follows: from 8 (eight locations used as a research site contained about 15 the number of lemur groups by the number of individuals around 21 tail.

Research conducted by the Center for Biodiversity & Conservation in collaboration with the University of Indonesia PSBKUI Wildlife Comata Study Group is a premiere surveys for the slow loris TNGGP and only include locations at the Resort Bodogol on Field Management Region III TN Bogor. Subsequent research conducted by Jarot Arisona (2007) of Population Studies, Behavior and Ecology of Java Slow Loris (Nycticebus javanicus Geoffroy, 1812) In Forest National Park Bodogol Pangrango Mount Gede, West Java. Based on the results of research conducted by Jarot Arisona this we can conclude some of the following as initial data the existence of Java Slow Loris (Nycticebus javanicus Geoffroy, 1812) in the region TNGGP:
1. Javanese lemurs in the forest survey Bodogol TNGGP done as much as 66 times (29 times in the forest 37 times in primary & secondary forest).
2. Surveys conducted in primary forests on seven lines, while in secondary forest observations conducted at six transect lines.
3. Repetition of the surveys were conducted three to four times for each transect.
4. Java is not spread evenly slow loris. There are individuals who live in one area alone and there are roaming individuals home range area overlap (overlap) one another.
5. Java lemur density in primary forest was lower (4.29 individual/km2) compared with the density of Javanese lemurs on a secondary forest (12.16 individual/km2).
6. Javanese lemurs the observed composition in primary forest and secondary forest showed that the number of adult individuals more than younger individuals.
7. Slow loris Java can be found as solitary individuals or as groups.
8. Each group comprised of lorises encountered two individuals with the composition of each group varies the pair consisting of an adult male individual with an individual adult female or a pair consisting of two individuals adult transplant or adult female with her baby.
9. Java slow loris is more often show a neutral response (58.33%) than negative responses (41.67%). It can be an indication that human disturbances in forest Bodogol still low.
10. Javanese lemurs on activity patterns of primary forest was significantly different patterns of activity in the primary forest lemurs.
11. Slow loris females more active than males.
12. Although the movement is slow, slow loris has a wide range of posture in motion with the following percentage, 24% sit, climb down 12%, sleeping ball 12%, 10% quadropedal walk, walk upside down quadropedal 10%, climb up 9%, 6% quadropedal stand , bridge 6%, 5% quadropedal hangs, hangs bipedal 4%, 2% tripedal hangs.
13. The most frequent use of slow loris java twigs or branches 5-10 cm in diameter (36.11%), then a small twig diameter <1cm (25%), branch or trunk diameter> 10 cm (22.22%), large twig diameter 1 - 5 cm (13.89%), and lianas (2.76%).
14. Level of vegetation that is used is the level of 5-35 cm diameter pole (52.78%), tree diameter> 35cm (30.56%), and saplings 5-10 cm in diameter (16.67%).
15. The observed tree species used for the move is a slow loris Java Rasamala (Altingia excelsa), Pine (Pinus perkusii), Replace (Quercus lineata), rattan (Calamus sp.) Mangong (Macaranga rhizinoides) and Kaliandra (Caliandra calothryrsus).

Endangered slow loris

Based on monitoring conducted suvey and ProFauna from 2000 to 2006, estimated that each year there are approximately 6000 to 7000 animals per day are captured from the wild in Indonesia for trade. This becomes a serious threat to the preservation in the wild, given the proliferation of fairly slow lorises, which only give birth to one offspring in a year and a half. Another problem is the absence of definitive scientific data on wild populations in the wild. Lorises are nocturnal and slow moving makes it very difficult to see in the wild. Surprisingly captors lemurs could easily find in the wild. Concern unwitting population in the wild will come down drastically due to the arrest to be traded. Although lemurs have been protected, but the law enforcement efforts must be improved. Protection at the international level more stringent by including lemurs in Appendix I of CITES help lemurs to remain stable. Because the slow loris has been protected by the laws of the Republic of Indonesia, the Indonesian government is fitting also supports efforts to raise the status of lemurs for entry in Appendix I of CITES. Thus international trade in slow lorises will not be longer than the natural result of the arrest.
