The bamboo lemurs or gentle lemurs are the lemurs in genus Hapalemur. These medium-sized primates live exclusively on Madagascar.

Etymology

Bamboo lemurs were first described by French zoologist Isidore Geoffroy Saint-Hilaire in 1851. Comparing their small size, proportions, speckled fur, and other traits to those of marmosets—then classified in the genus Hapale—he named the genus Hapalemur. Hapale derives from the Greek word ἁπαλός (hapalos), meaning "gentle". [4]

In their discussion of lemur name etymologies, Dunkel et al. speculated that the once popular vernacular name for the genus, "gentle lemur", derived from the translation of Hapalemur, despite their notoriety for being one of the most aggressive lemurs in captivity—an observation first noted in a letter by Dutch naturalist François Pollen published in 1895. More recently, the common name "bamboo lemur" first appeared in the mid- to late-1980s following the rediscovery of the greater bamboo lemur (Hapalemur simus). However, the name became more generally used a year or two later following the discovery of the golden bamboo lemur (Hapalemur aureus) in 1987. For a few years, both names or combinations of both were widely used, but "bamboo lemur" became the preferred name in 1994 with the publication of the first edition of Lemurs of Madagascar . The term "gentle lemur" has seen little use in both popular and academic literature since the early 2000s. [4]

Description

Lesser bamboo lemur (Hapalemur griseus)

The bamboo lemurs are characterized by a grey-brown fur, which varies by species. Their muzzles are short and their ears are round and hairy. Lengths vary from 26 to 46 cm (10.2 to 18.1 inches), with tails just as long or longer, and they weigh up to 2.5 kg (5.5 pounds.)

Bamboo lemurs prefer damp forests where bamboo grows. Although they can be active any time of the day, they are often active just after dawn. Though primarily arboreal, they sometimes come down to the ground. The Lac Alaotra gentle lemur or "bandro" (Hapalemur alaotrensis), which lives in the reed beds of Lac Alaotra, spends much of its time in water and can swim well, unlike other lemur species, which only venture to water to drink.

The lesser gentle lemurs live together in groups of three to five animals, which probably represent families composed of a male, one or two females, and their offspring. They communicate with a variety of sounds.

Gestation lasts 135 to 150 days and ends between September and January, when the female bears one to two young. These are weaned after about four months (if the food supply is ample) and are fully mature at two years of age. Their life expectancy is up to 12 years.

Cyanide consumption

Not all bamboo contain cyanide, but H. aureus selects the growing tips of Cephalostachyum viguieri , which contain 15 mg of cyanide per 100 g (3.5 oz). Other bamboo lemurs have been found to consume less cyanogenetic forms of bamboo, such as mature shoots of C. viguieri or the leaves of Cephalostachyum perrieri. [5] How certain bamboo lemurs can detoxify the high amounts of cyanide in their diets is unknown. [6]

Classification

As of 2010, the classification of bamboo lemurs lists five species and three subspecies. [7] The greater bamboo lemur was removed from this genus in 2001 to Prolemur [8] but was restored in 2016. [9]

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 sportive lemurs are the medium-sized primates that make up the family Lepilemuridae. The family consists of only one extant genus, Lepilemur. They are closely related to the other lemurs and exclusively live on the island of Madagascar. For a time, this family was named Megaladapidae, but the current name was given precedence since the extinct genus Megaladapis was removed from the family.

Lake Alaotra is the largest lake in Madagascar, located in Alaotra-Mangoro Region and on the island's northern central plateau. Its basin is composed of shallow freshwater lakes and marshes surrounded by areas of dense vegetation. It forms the center of the island's most important rice-growing region. It is a rich habitat for wildlife, including some rare and endangered species, as well as an important fishing ground. Lake Alaotra and its surrounding wetlands cover 7,223 square kilometres (2,789 sq mi), and include a range of habitats, including open water, reedbeds, marshes, and rice paddies. The lake itself covers 900 km2 (350 sq mi). Lake Alaotra was declared a wetland of international importance under the international Ramsar Convention on February 2, 2003.

Ankarana Special Reserve is a protected area in northern Madagascar created in 1956. It is a small, partially vegetated plateau composed of 150-million-year-old middle Jurassic limestone. With an average annual rainfall of about 2,000 millimetres (79 in), the underlying rocks have been eroded to produce caves and feed subterranean rivers—a karst topography. The rugged relief and the dense vegetation have helped protect the region from human intrusion.

They are vertical climbers and jump from stalk to stalk in thick bamboo forests.

<span class="mw-page-title-main">Lac Alaotra bamboo lemur</span> Species of lemur

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".

<i>Pachylemur</i> Extinct genus of lemurs

Pachylemur is an extinct, giant lemur most closely related to the ruffed lemurs of genus Varecia. Two species are known, Pachylemur insignis and Pachylemur jullyi, although there is some doubt as to whether or not they may actually be the same species. Pachylemur is sometimes referred to as the giant ruffed lemur, because although it and the living ruffed lemurs had similar teeth and skeletons, Pachylemur was more robust and as much as three to four times larger. DNA studies have confirmed a sister group relationship between these two types of lemur. Like living ruffed lemurs, Pachylemur specialized in eating fruit, and was therefore an important seed disperser, possibly for tree species with seeds too large for even ruffed lemurs to swallow. In the spiny thickets of southwestern Madagascar, they were also likely to have dispersed seeds evolved to attach to fur and be carried away. Unlike ruffed lemurs, the fore- and hindlimbs of Pachylemur were nearly the same length, and therefore it was likely to be a slow, deliberate climber. However, both used hindlimb suspension to reach fruit on small branches below them.
