TL;DR: A conservation action plan for the Mentawai Islands is presented in this paper, which evaluates the status of and makes conservation recommendations for the four endemic primates of the MentAWai Islands: Kloss's gibbon (Hylobates klossii primates of Mentawali Islands: KG), simakobu monkey (Simias concolor), Mentawi macaque (Macaca pagensis), and Mentawahi langur (Presbytis potenziani langur).
Abstract: In this Conservation Action Plan, I evaluate the status of and make conservation recommendations for the four endemic primates of the Mentawai Islands: Kloss's gibbon (Hylobates klossii primates of the Mentawai Islands: Kloss's gibbon (Hylobates klossii primates of the Mentawai Islands: Kloss's gibbon ( ), the simakobu monkey (Simias concolor), the Mentawai langur (Presbytis potenziani langur (Presbytis potenziani langur ( ), and the Mentawai macaque (Macaca pagensis). There are two subspecies of each of the cercopi- thecines. They are threatened mainly by hunting and commercial logging. This action plan follows up on the recommendations made for the Mentawai primates in the IUCN/SSC Primate Specialist Group's Action Plan for Asian Primate Conservation: 1987-91 by Ardith Eudey, and includes data and recommendations from researchers who have studied them since 1980. I also include a brief history of conservation action in the Mentawai Islands to put these recommendations in a historical context. I recommend the following conservation status changes: Kloss's gibbon, Endangered; simakobu monkey, Critically Endangered; Mentawai langur, Endangered; and Mentawai macaque, Vulnerable. The largest populations of the four species can be found in Siberut National Park on the largest and northernmost island, but all but Kloss's gibbon have distinct subspecies on the southern islands of Sipora, North Pagai, and South Pagai, and these are urgently in need of protective measures. The national park is remote and diffi cult to access by researchers and tourists. I suggest the following conservation actions: 1) increased protection for the Siberut National Park, which currently lacks enforcement; 2) formal protection of the Peleonan forest in North Siberut, which is home to unusually high primate populations and is easily accessible; 3) protect areas in the Pagai Islands by cooperating with a logging corporation that has practiced sustainable logging techniques there since 1971; 4) conservation education, especially regarding hunting; and 5) the development of alternative economic models for the local people to reduce the likelihood of selling

TL;DR: In this paper, the authors present recent data on deforestation rates and primate distribution patterns to argue, yet again, for action to avert potential extinctions of Sumatran primates in the near future.
Abstract: The severe declines in forest cover on Sumatra and adjacent islands have been well-documented but that has not slowed the rate of forest loss. Here we present recent data on deforestation rates and primate distribution patterns to argue, yet again, for action to avert potential extinctions of Sumatran primates in the near future. Maps of forest loss were constructed using GIS and satellite imagery. Maps of primate distributions were estimated from published studies, museum records and expert opinion, and the two were overlaid on one another. The extent of deforestation in the provinces of Sumatra between 2000 and 2012 varied from 3.74% (11,599.9 ha in Lampung) to 49.85% (1,844,804.3 ha in Riau), with the highest rates occurring in the provinces of Riau, Jambi, Bangka Belitung and South Sumatra. During that time six species lost 50% or more of their forest habitat: The Banded langur Presbytis femoralis lost 82%, the Black-And-white langur Presbytis bicolor lost 78%, the Black-crested Sumatran langur Presbytis melalophos and the Bangka slow loris Nycticebus bancanus both lost 62%, the Lar gibbon Hylobates lar lost 54%, and the Pale-Thighed langur Presbytis siamensis lost 50%. Two species, the Pagai langur Presbytis potenziani and the Pagai macaque Macaca pagensis, both from the southern part of the Mentawai islands, are not represented in national parks or protected areas at all, and a further five species are found in only one protected area. The causes of deforestation are many and varied, but by far the leading causes are logging, followed by fire and/or conversion to plantations. Enforcement of existing regulations protecting primates, disentanglement of land claims and overlapping boundaries, a halt to logging in existing forests, a halt to road building through forests, clarification of how traditional adat law relates to protected areas, and the creation of new, enforceable laws protecting species from trade and exploitation will all be needed if Indonesia is to uphold the commitments to primate conservation that it has already made.

TL;DR: Sur la base of ces caracteres, nous concluons qu'il represente bien une espece distincte, M. siberu, dont il est morphologiquement bien distinct.
Abstract: Bien que Macaca pagensis soit connu des Iles Mentawai depuis le debut du XX e siecle, on ne savait rien d'une de ces iles, Pulau Siberu, jusqu'en 1970. C'est par hasard que Fuentes et Olson (1995) ont nomme le macaque de Siberut M. p. siberu. Deux specimens seulement de ce macaque sont connus: un mâle decrit comme un hybride de Padang, Sumatra, qui a vecu au Zoo de Londres jusqu'en 1933, et un mâle qui a vecu au Zoo de Bristol jusqu'en 1997. Dans cet article, nous decrivons en detail pour la premiere fois le macaque de Siberut, d'apres ces deux specimens. Nous l'avons compare avec d'autres especes du groupe M. nemestrina dont il est morphologiquement bien distinct. Sur la base de ces caracteres, nous concluons qu'il represente bien une espece distincte, M. siberu.
TL;DR: Taking together the paraphyletic origin of Mentawai macaques and genetic differences detected among pigtailed macaque populations, it is proposed to separate macaques from Siberut and Sipora, North and South Pagai into two distinct species, Macaca siberu and Macaca pagensis, respectively.
