Cathariostachys Madagascariensis
''Cathariostachys madagascariensis'', the Madagascar giant bamboo or in Malagasy language, is a bamboo species found in Madagascar. Description The culms are tall and erect, usually between but occasionally reaching up to ; with arching or drooping upper sections often leaning on nearby trees or vegetation for partial support. Culm diameters vary between 5 and 8 (up to 12) cm in diameter with internodes between 40 and 60 cm. Young shoots are pale to purplish green and covered with sharp, stiff, black to brown hairs. The rhizomes have very long, narrow necks, long, which help it to spread much more rapidly than most clumping forms of bamboo. Shoots are quite bitter and have high concentrations of cyanide. Flowers are both determinant and hemispherical, an unusual form for bamboos. Range and habitat C. ''madagascariense'' is endemic to the interior of Madagascar and can be found in lower montane forests, at forest margins, in disturbed forest, or in areas of open ground at ele ...

Aimée Antoinette Camus
Aimée Antoinette Camus (1 May 1879 – 17 April 1965) was a French botanist. She was best known for her study of orchids and oaks. Camus also has the legacy of authoring the second highest number of land plant species among female scientists, in total naming 677 species. Camus was the daughter of Edmond Gustave Camus, also a botanist, and was born in L'Isle-Adam, about 50 kilometres north of Paris. Under her father's influence she specialized in the study of orchids and the anatomy of the plant and worked for some time with other professionals such as Paul Bergon (1863-1912) and Paul Henri Lecomte (1856-1934). Her sister was the painter Blanche-Augustine Camus (1881-1968). She also produced a major treatment of the oaks and stone oaks, providing the first comprehensive systematic treatment of the latter genus. Camus published the work ''L'Iconographie des Orchidées d´Europe et du Bassin Méditerranéen''. She gave the name of ''Neohouzeaua'' to a genus of seven tropi ...

Malagasy Language
Malagasy (; ) is an Austronesian language and the national language of Madagascar. Malagasy is the westernmost Malayo-Polynesian language, brought to Madagascar by the settlement of Austronesian peoples from the Sunda islands around the 5th century AD. The Malagasy language is one of the Barito languages and is most closely related to the Ma'anyan language, still spoken on Borneo to this day. Malagasy also includes numerous Malay loanwords, from the time of the early Austronesian settlement and trading between Madagascar and the Sunda Islands. After c. 1000 AD, Malagasy incorporated numerous Bantu and Arabic loanwords, brought over by traders and new settlers. Malagasy is spoken by around 25 million people in Madagascar and the Comoros. Most people in Madagascar speak it as a first language, as do some people of Malagasy descent elsewhere. Malagasy is divided between two main dialect groups; Eastern and Western.

Bamboo
Bamboos are a diverse group of evergreen perennial flowering plants making up the subfamily Bambusoideae of the grass family Poaceae. Giant bamboos are the largest members of the grass family. The origin of the word "bamboo" is uncertain, but it probably comes from the Dutch or Portuguese language, which originally borrowed it from Malay or Kannada. In bamboo, as in other grasses, the internodal regions of the stem are usually hollow and the vascular bundles in the cross-section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody xylem is also absent. The absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos, to be columnar rather than tapering. Bamboos include some of the fastest-growing plants in the world, due to a unique rhizome-dependent system. Certain species of bamboo can grow within a 24-hour period, at a rate of almost an hour (equivalent to 1 mm every 90 seco ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Madagascar Subhumid Forests
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. Geography The Madagascar subhumid forests ecoregion covers Madagascar's highlands, which extend north and south along the length of the island, above approximately elevation on the east and above meters elevation on the west. The Central Highlands is the largest highland region on the island, extending from approximately 16º to 23º south. The Central Highlands include Ankaratra and the Andringitra Massif, which is home to Pic Boby (2,658 m), the Central Highlands' highest peak.Everson, Kathryn M.; Jansa, Sharon A.; Goodman, Steven M.; Olson, Link E..

Ranomafana National Park
Ranomafana National Park is in the southeastern part of Madagascar in Haute Matsiatra and Vatovavy. With more than 41,600 hectares (161 square miles) of tropical rainforest, it is home to several rare species of flora and fauna including the golden bamboo lemur, the greater bamboo lemur, black and white ruffed lemur and Milne-Edwards sifaka, and over 130 species of frogs. Bird species including ground rollers, blue vangas, short-legged ground rollers and brown mesites can be seen. The park was established in 1991 with the purpose of conserving the unique biodiversity of the local ecosystem and reducing the human pressures on the protected area. It is part of the World Heritage Site Rainforests of the Atsinanana. Adjacent to the park is the Centre ValBio research station, established in 2003 and managed by Stony Brook University with a focus on biodiversity research, community health and education, environmental arts and reforestation. The place name comes from the Malagasy w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bamboo Lemur
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". 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 greate ...

Cyanogenesis
Cyanide is a naturally occurring, rapidly acting, toxic chemical that can exist in many different forms. In chemistry, a cyanide () is a chemical compound that contains a functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom. In inorganic cyanides, the cyanide group is present as the anion . Soluble salts such as sodium cyanide (NaCN) and potassium cyanide (KCN) are highly toxic. Hydrocyanic acid, also known as hydrogen cyanide, or HCN, is a highly volatile liquid that is produced on a large scale industrially. It is obtained by acidification of cyanide salts. Organic cyanides are usually called nitriles. In nitriles, the group is linked by a covalent bond to carbon. For example, in acetonitrile (), the cyanide group is bonded to methyl (). Although nitriles generally do not release cyanide ions, the cyanohydrins do and are thus rather toxic. Bonding The cyanide ion is isoelectronic with carbon monoxide and wi ...
