The golden bamboo lemur (Hapalemur aureus), bokombolomena or varibolomena in Malagasy, is a medium-sized bamboo lemur endemic to south-eastern Madagascar.
It is able to ingest twelve times as much cyanide as would be considered lethal for other species of its size.
The golden bamboo lemur is crepuscular i.e. is a most active at dawn and dusk. It is about the size of a domestic cat and is 28–45 cm (11–18 in) long plus a tail of 24–40 cm (9.4–15.7 in), and on average weighs 1.6 kg (3.5 lb). [4]
The species is endemic to the rain forests of south–eastern Madagascar at elevations of 600–1,400 m (2,000–4,600 ft). It is known from the vicinity of Ranomafana National Park (first discovery in 1986 by Patricia Wright), Andringitra National Park (discovered in 1993), possibly in a forest corridor that connects Ranomafana with Andringitra National Park. [1]
As its name indicates, this lemur feeds almost exclusively on grasses, especially the giant bamboo or volohosy ( Cathariostachys madagascariensis ) feeding on new shoots, leaf bases and the creepers. [5] The growing shoots of this bamboo contain 0.015% (1 part in 6667) of cyanide. Each adult lemur eats about 500 g (18 oz) of bamboo per day, which contain about twelve times the lethal dose of cyanide for most other animals of this size. [6] [4]
They live in small groups of two to six individuals and have a home range of up to 80 hectares (0.31 sq mi). but usually move less than 400 m (1,300 ft) in a day. Females have a gestation period of approximately 138 days and give birth to one infant (occasionally two) at the beginning of the rainy season, in November or December. The young are highly dependent on their mothers and are kept hidden in dense vegetation for the first two weeks. [1] [4]
The golden bamboo lemur was discovered in 1986 by Dr. Patricia Wright and Bernhard Meier, [7] in what is now Ranomafana National Park. The park was opened in 1991 to protect this endangered lemur, as well as several other lemur species and its flora and fauna. The population is declining, predominantly due to hunting and to ongoing habitat loss; with only about 1,000 individuals remaining. The principal loss of habitat is due to slash-and-burn agriculture or the harvesting of bamboo, for use as a building material as well as for carrying water and basket making. The species is classified as critically endangered by the International Union for Conservation of Nature (IUCN) and is listed on Appendix I of CITES, CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention).

Lemuridae is a family of strepsirrhine primates native to Madagascar and the Comoros. They are represented by the Lemuriformes in Madagascar with one of the highest concentration of the lemurs. One of five families commonly known as lemurs. These animals were once thought to be the evolutionary predecessors of monkeys and apes, but this is no longer considered correct. They are formally referred to as lemurids.
The Madagascar lowland forests or Madagascar humid forests are a tropical moist broadleaf forest ecoregion found on the eastern coast of the island of Madagascar, home to a plant and animal mix that is 80 to 90% endemic, with the forests of the eastern plain being a particularly important location of this endemism. They are included in the Global 200 list of outstanding ecoregions.
The bamboo lemurs or gentle lemurs are the lemurs in genus Hapalemur. These medium-sized primates live exclusively on Madagascar.
The red-bellied lemur is a medium-sized strepsirrhine primate with a luxuriant chestnut brown coat. This lemur is endemic to eastern Madagascan rainforests and is distinguished by patches of white skin below the eyes, giving rise to a "teardrop" effect, particularly conspicuous in the male.
Patricia Chapple Wright is an American primatologist, anthropologist, and conservationist. Wright is best known for her extensive study of social and family interactions of wild lemurs in Madagascar.
The greater bamboo lemur, also known as the broad-nosed bamboo lemur and the broad-nosed gentle lemur, is a species of lemur endemic to the island of Madagascar.
The eastern lesser bamboo lemur, also known as the gray bamboo lemur, the gray gentle lemur, and the Mahajanga lemur is a small lemur endemic to Madagascar, with three known subspecies. As its name suggests, the eastern lesser bamboo lemur feeds mainly on bamboo. The lemurs of the genus Hapalemur have more manual dexterity and hand–eye coordination than most lemurs. They are vertical climbers and jump from stalk to stalk in thick bamboo forests.
Ranomafana National Park is a national park in southeastern Madagascar, in the Haute Matsiatra and Vatovavy regions. It was established as Madagascar's fourth national park in 1991 following the rediscovery of the greater bamboo lemur and the discovery of the golden bamboo lemur by the primatologist Dr. Patricia Wright.
The Lac Alaotra bamboo lemur, also known as the Lac Alaotra gentle lemur, Alaotran bamboo lemur, Alaotran gentle lemur, Alaotra reed lemur, or locally as the bandro, is a bamboo lemur. It is endemic to the reed beds in and around Lac Alaotra, in northeast Madagascar. It is about 40 cm (16 in) long, with a similar length tail, and is a brownish-gray colour. It is the only bamboo lemur to live in and feed on papyrus reeds, and other reeds and grasses, and some authorities argue that it should be regarded as a subspecies of the eastern lesser bamboo lemur. The population of this lemur has been declining because of habitat destruction and the International Union for Conservation of Nature has rated it as being "critically endangered".
The small-toothed sportive lemur, or small-toothed weasel lemur, is a primate species in the family Lepilemuridae that—like all extant lemurs—is endemic to Madagascar. The species lives in dense rainforest in southeastern Madagascar, and can be found in Ranomafana and Andringitra National Parks. Described in 1894, it was considered either a subspecies or taxonomic synonym of the weasel sportive lemur throughout most of the 20th century. Phylogenetic studies not only support its species status, but also suggest that it is the only eastern Malagasy sportive lemur that is more closely related to western than to other eastern species.
The western lesser bamboo lemur, also known as the northern bamboo lemur, western gentle lemur, or Sambirano lesser bamboo lemur, is a species of bamboo lemur endemic to Madagascar.
The southern lesser bamboo lemur, also known as the southern bamboo lemur, rusty-gray lesser bamboo lemur, and southern gentle lemur, is a species of bamboo lemur endemic to southern Madagascar.
The Betsileo sportive lemur is a sportive lemur endemic to Madagascar. Like all members of its genus, it is nocturnal and largely folivorous. It is threatened by habitat loss.
Randrianasolo's sportive lemur, or the Bemaraha sportive lemur, is a sportive lemur endemic to a small area of western Madagascar. It is threatened by habitat loss.
Cathariostachys madagascariensis, the Madagascar giant bamboo or volohosy in Malagasy language, is a bamboo species found in Madagascar.
Milne-Edwards's sifaka, or Milne-Edwards's simpona, is a large arboreal, diurnal lemur endemic to the eastern coastal rainforest of Madagascar. Milne-Edwards's sifaka is characterized by a black body with a light-colored "saddle" on the lower part of its back. It is closely related to the diademed sifaka, and was until recently considered a subspecies of it. Like all sifakas, it is a primate in the family Indriidae.
Lemurs' Park is a small botanical garden and lemur reserve covering 5 ha, and is located 22 km (14 mi) southwest of Antananarivo, Madagascar. It was founded around 2000 by Laurent Amouric and Maxime Allorge. Most of its nine lemur species are free-ranging within the park, which also contains more than 70 of Madagascar's endemic plant species. The park is open to the public, offering guided tours as well as standard amenities, a gift shop, and a restaurant. Visitors can arrange transportation between downtown Antananarivo and Lemurs' Park on a private park shuttle.
Groves' dwarf lemur is a species of dwarf lemur known from Ranomafana and Andringitra national parks and surrounding areas in southeastern Madagascar. The identification was based on comparison of mitochondrial and nuclear gene sequences with other members of the C. crossleyi group. Individuals from this clade first came under genetic study in 1999 and were recognized as a new species in 2014, but it was not formally described until 2017. The lemur was named after mammalologist Colin Groves. Known from altitudes from 754 to 999 m, it is significantly larger than other members of the C. crossleyi group, with a 20 cm body length, a 29 cm tail, and a weight of 0.41 kg. While the conservation status of the new species has not yet been assessed, its presence in several national parks does not guarantee that it will not be threatened by deforestation ongoing on the island, or possibly by hunting.
