The Golden Bamboo Lemur (Hapalemur aureus) is a medium-sized bamboo lemur endemic to south-eastern Madagascar. is most active at dawn and dusk. The golden bamboo lemur, apparently tolerant of high concentrations of cyanide, eats the cyanide containing leaf bases, shoots, and piths of new-growth giant bamboo. Description The golden bamboo lemur is crepuscular i.e. [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. The lemurs are the most basal living primate, derived from a lineage that has evolved independe… viguieri. Golden Bamboo Lemur ~ Hapalemur aureus General Information Class: Mammalia Order: Primates Family: Lemuridae Genus: Hapalemur Species: Golden Bamboo L H. simus prefers the woody pulp and culms of C. cf. It’s discovery in the mid-1980’s was a crucial factor that led to the foundation of the now famous Ranomafana National Park – a reserve that protects over 400 sq. Some manifestations of toxicity are subtle. Bamboo lemurs are a genus of 5 species, and the only primate in the world that specializes in the bamboo diet. On the other hand, the Golden Bamboo Lemur eats an average of 500 g of this cyanide laden bamboo every day, thus intaking an estimated 12 times the toxic dose for a primate of its body mass. There are three species of Bamboo lemurs: the Greater Bamboo Lemur (H. simus), three subspecies of the Lesser or Gentle Bamboo Lemur, (H. griseus), and the Golden Bamboo Lemur, (H. aureus), who has the dubious honor of being the world's most recently discovered primate, having been found by Dr. Patricia Wright of SUNY Stonybrook in 1984. This species has been transformed and developed to resist high levels of cyanide, which eat in small amounts of bamboo leaves. [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). Madagascar, an island off the southeast coast of Africa, is home to the group of primates known as the lemurs. More than 90% of the diets of the Greater Bamboo Lemur (Prolemur simus) and Golden Bamboo Lemur (Hapalemur aureus) are cyanide-producing bamboo. The park was created in 1991. In the 1 pound of bamboo that golden bamboo lemurs eat daily, they consequently consume twelve times the lethal dose of cyanide in comparable mammals. The golden bamboo lemur is so called because of the golden fur around its face, inner limbs and belly. 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). [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). These are weaned after about four months (if the food supply is ample) and are fully mature at two years of age. The Golden bamboo lemur has evolved with a resistance to the extreme levels of cyanide in the leaves of the young bamboo that it eats. Unfortunately, the mechanism H. aureus uses to detoxify this poison is as yet unknown. How bamboo lemurs can detoxify the high amounts of cyanide (from bamboo shoots) in their diets is unknown. Hapalemur aureus Discovered in 1987, critically endangered due to its very specialised diet of Volohosy bamboo leaves, a tree endemic to Madagascar. is most active at dawn and dusk.

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. The growing tips of Cephalostachyum ef uiguieri selected by the golden bamboo lemur (Hapalemuraureus) contained 15 mg of cyanide per 100 g fresh weight bamboo while the leaves of C. perrieri selected by the gentle bamboo lemur (H. griseus)and the mature culms of C. cf uiguieri selected by the greater bamboolemur (H. simus) did not contain cyanide. 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. It is 28–45 cm long plus a tail of 24–40 cm, and weighs on average 1.6 kg. Gestation lasts 135 to 150 days and ends between September and January, when the female bears one to two young. PLEASE NOTE:"Poisonous" does not mean deadly. The answer is simple: cyanide. The golden bamboo lemur is known for feeding primarily on the new shoots of the giant bamboo plant, which contains 12x the lethal dose of cyanide ☠️ per pound (what the golden bamboo lemur eats in a day). 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. How then is major competition avoided? of tropical forest. The growing tips of Cephalostachyum ef uiguieri selected by the golden bamboo lemur (Hapalemuraureus) contained 15 mg of cyanide per 100 g fresh weight bamboo while the leaves of C. perrieri selected by the gentle bamboo lemur (H. griseus)and the mature culms of C. cf uiguieri selected by the greater bamboolemur (H. simus) did not contain cyanide. With an adult weight of approximately 1.3–1.7 kg, it is the largest member of the genus Hapalemur, since the greater bamboo lemur (formerly H. simus) has now been placed in its own genus, Prolemur (see Groves, 2001). km. but usually move less than 400 m (1,300 ft) in a day.

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).[1][5][2]. The giant and grey bamboo lemurs eat from parts of the plant which are very low in cyanide (safe doses like in almonds) or from which cyanide is virtually absent. These three sympatric species inhabit the same habitat and feed on the same bamboo species, Cephalostachyum cf viguieri and C. perrieri. Consumption of cyanogenic bamboo by a newly discovered species of bamboo lemur. But the reason I am writing about little buddy the golden bamboo lemur is because it eats primarily the fresh young shoots of the giant bamboo, which are just chock full of cyanide.

Lemurs are a special type of primate called prosimians, which are the oldest group of primates. However, large amounts of cyanide have been measured in the feces which are the food source specifically selected … A cyanide is a chemical compound that contains the group C≡N. The question then arises, what prevents the H. griseus from encroaching on the territory of their cousins by eating the shoots of both bamboo species? Every day the golden bamboo lemur eats around 500g of soft stalks and growing tips of giant bamboo, which represents 12 times the lethal dose of cyanide for … The golden bamboo lemur is crepuscular i.e. The park was opened in 1991 to protect this endangered lemur, as well as several other lemur species and its flora and fauna. The amount of cyanide consumed daily by this species is enough to kill three men. The growing tips of Cephalostachyum ef uiguieri selected by the golden bamboo lemur (Hapalemuraureus) contained 15 mg of cyanide per 100 g fresh weight bamboo while the leaves of C. perrieri selected by the gentle bamboo lemur (H. griseus)and the mature culms of C. cf uiguieri selected by the greater bamboolemur (H. simus) did not contain cyanide. If the forest is damaged by fire or trees are cut, other faster imported tree species like eucalyptus will grow, leaving no space for new Volohosy trees. With fewer than a thousand individuals remaining in the wild, the Critically Endangered Golden Bamboo Lemur (Hapalemur aureus) holds on to a tenuous existence in the rainforests of Madagascar.

Each adult lemur eats about 500 g (18 oz) of bamboo per day, which contain about 12 times the lethal dose of cyanide for most other animals of this size. However, large amounts of cyanide have been measured in the feces which are the food source specifically selected by a species of dung beetle who seems to have co-evolved with the Golden bamboo Lemur. viguieri, while H. griseus eats the leaf bases of both species and selects the shoots of C. perrieri. The golden bamboo lemur was first discovered in 1985, and was described two years later (Meier et al., 1987). viguieri contain 15 mg of cyanide per 100 g of fresh weight. The population is declining, predominantly due to hunting and to ongoing habitat loss; with only about 1,000 individuals remaining. The golden bamboo lemur feeds on young shoots, creepers and leaf bases of the endemic giant bamboo (Cephalostachium viguieri) (4), and has evolved to be resistant to the high concentrations of cyanide found within the tissues of this plant (3).Around 500 g of bamboo are eaten every day; this represents roughly 12 times the usual mammalian lethal dose of cyanide (4). The H. griseus stay away from the shoots of this plant because they are highly toxic. H. aureus meanwhile eats only the shoots of C. cf. The golden bamboo lemur is crepuscular.
