Demographic features of the population of Madagascar include population density, ethnicity, education level, health of the populace, economic status, religious affiliations and other aspects of the population.
Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm Bombyx mori reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors.
The aye-aye is a long-fingered lemur, a strepsirrhine primate native to Madagascar with rodent-like teeth that perpetually grow and a special thin middle finger that they can use to catch grubs and larvae out of tree trunks.
Bombyx mori, commonly known as the domestic silk moth, is a moth species belonging to the family Bombycidae. It is the closest relative of Bombyx mandarina, the wild silk moth. Silkworms are the larvae of silk moths. The silkworm is of particular economic value, being a primary producer of silk. The silkworm's preferred food are the leaves of white mulberry, though they may eat other species of mulberry, and even leaves of other plants like the osage orange. Domestic silk moths are entirely dependent on humans for reproduction, as a result of millennia of selective breeding. Wild silk moths, which are other species of Bombyx, are not as commercially viable in the production of silk.
The Madagascar subhumid forests are a tropical moist broadleaf forest ecoregion that covers most of the Central Highlands of the island of Madagascar. They are included in the WWF's Global 200 list of outstanding ecoregions. Most of the original habitats have been lost due to human pressure.
The fauna of Madagascar is a part of the wildlife of Madagascar.
Nepenthes madagascariensis is one of two Nepenthes pitcher plant species native to Madagascar, the other being N. masoalensis.
Chrysiridia rhipheus, the Madagascan sunset moth, is a species of day-flying moth of the family Uraniidae. It is considered one of the most impressive and appealing-looking lepidopterans. Famous worldwide, it is featured in most coffee table books on Lepidoptera and is much sought after by collectors, though many older sources misspell the species name as "ripheus". The colours originate from optical interference in the iridescent parts of the wings, while the black parts are pigmented. Adults have a wingspan of 7–9 cm (2.8–3.5 in).
Isalo National Park is a National Park in the Ihorombe Region of Madagascar, in the southwestern corner of the Province of Fianarantsoa. The closest town is Ranohira, and the closest cities are Toliara and Ihosy. It is a sandstone landscape that has been dissected by wind and water erosion into rocky outcrops, plateaus, extensive plains and up to 200 m (660 ft) deep canyons. There are permanent rivers and streams as well as many seasonal watercourses. Elevation varies between 510 and 1,268 m.
The lesser chameleon or minor chameleon is a species of lizards in the family Chamaeleonidae. It is endemic to Madagascar.
The Madagascan flying fox, Madagascar flying-fox, or Madagascar fruit bat is a species of megabat in the genus Pteropus. It is endemic to Madagascar. Its natural habitats are diverse, and include moist lowland forests, dry forests, succulent woodlands, and spiny thickets, and mangroves. It eats figs and other fruits, flowers, and leaves. It is threatened by habitat loss.
Wild silks have been known and used in many countries from early times, although the scale of production is far smaller than that from cultivated silkworms. Silk cocoons and nests often resemble paper or cloth, and their use has arisen independently in many societies.
The Bara people are a Malagasy ethnic group living in the southern part of the central plateaus of Madagascar, in the Toliara Province, concentrated around their historic capital at Ihosy. The Bara are the largest of the island's zebu-herding peoples and have historically lived a semi-nomadic lifestyle, although an increasing proportion are practicing agriculture. Bara society is highly patriarchal and endogamy and polygamy are practiced among some Bara tribes. Young men practice cattle rustling to prove their manhood before marriage, and the kilalaky musical and dance tradition associated with cattle rustlers has gained popularity across the island.
Philibert Rabezoza, better known by the name Rakoto Frah, was a flautist and composer of traditional music of the central highlands of Madagascar. Born in 1923 near the capital city of Antananarivo to a poor rural family, Rakoto Frah surmounted the challenges posed by his underprivileged origins to become the most acclaimed 20th century performer of the sodina flute, one of the oldest traditional instruments on the island. Through frequent international concerts and music festival performances, he promoted the music of the highlands of Madagascar and became one of the most famous Malagasy artists, both within Madagascar and on the world music scene.
The flora of Madagascar consists of more than 12,000 species of plants, as well as a poorly known number of fungi and algae. Around 83% of Madagascar's vascular plants are found only on the island. These endemics include five plant families, 85% of the over 900 orchid species, around 200 species of palms, and such emblematic species as the traveller's tree, six species of baobab and the Madagascar periwinkle. The high degree of endemism is due to Madagascar's long isolation following its separation from the African and Indian landmasses in the Mesozoic, 150–160 and 84–91 million years ago, respectively. However, few plant lineages remain from the ancient Gondwanan flora; most extant plant groups immigrated via across-ocean dispersal well after continental break-up.
The Kirindy Forest is a private nature reserve situated in western Madagascar, about 50 km northeast of the town of Morondava, near Ambivy. The forest reserve falls within the boundaries of the Kirindy Mitea National Park, which spreads further to the south.
Uapaca bojeri, or tapia, is a tree species endemic to Madagascar. A characteristic element of the Madagascan flora, it occurs in the central highlands, where it dominates a type of sclerophyllous forest or woodland. Tapia forest has a high ecological value due to the fauna, flora, and funga it harbours, and is of economic interest to the local population, e.g. for collection of tapia fruits, firewood, mushrooms or wild silkworms, and hunting. Local impact through fire and cutting is seen as a form of sustainable use however tapia woodlands are now found only in scattered, isolated stands totaling at most 132,255 ha. Native woody vegetation of the central highlands is increasingly replaced by grasslands, primarily due to increased fire frequency as areas are burned annually.
Borocera madagascariensis is a species of lasiocampid moth endemic to coastal Madagascar. It is one of three species of silk producing moths found on the island of Madagascar. B. madagascariensis is often confused with the similar Borocera cajani, which is distributed throughout the island and whose silk is more widely used for silk production. Many publications erroneously refer to B. cajani as B. madagascariensis. It shares the common name of landibe with B. cajani. The pupae of B. madagascariensis is consumed by the people of Madagascar, and is known in Malagasy as soherina.
