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 ...

Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...

Southern Lesser Bamboo Lemur
The southern lesser bamboo lemur (''Hapalemur meridionalis''), 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. Taxonomy It was originally considered to be a subspecies of the eastern lesser bamboo lemur (''Hapalemur griseus''), and is of similar size, but is darker and redder than the eastern lesser bamboo lemur, with a shorter tail and different vocalizations. The type locality is the forestry station of Mandena, and it is further supported as a separate species by recent mitochondrial DNA research. It is possible that hybridisation with ''H griseus'' occurs on the Andringitra Massif at altitudes of . Distribution The precise distribution is not known but it is found in south-eastern Madagascar from the Mananara River south to Andohahela and up to an altitude of .

Greater Bamboo Lemur
The greater bamboo lemur (''Hapalemur simus''), 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. Taxonomy Originally described as ''Hapalemur (Prolemur) simus'' by John Edward Gray in 1870, it was regarded simply as ''Hapalemur simus'' as early as 1880. With the understanding that this species is more closely related to the ring-tailed lemur (''Lemur catta'') than to the other ''Hapalemur'' species, Colin Groves resurrected ''Prolemur'' as a full genus in 2001, with this species as its only member. More recent research by Herrera and Dávalos (2016) indicates that the species is sister to all of ''Hapalemur'', and that ''Lemur'' is sister to ''Hapalemur'' + ''simus'', and that it should remain in ''Hapalemur''. Description The greater bamboo lemur is the largest bamboo lemur, at over . It has greyish brown fur and white ear tufts, and has a head-body length of around . They have relativel ...

Cyanide
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 a ...

Lac Alaotra Gentle Lemur
The Lac Alaotra bamboo lemur (''Hapalemur alaotrensis''), also known as the Lac Alaotra gentle lemur, Alaotran bamboo lemur, Alaotran gentle lemur, Alaotra reed lemur, or locally as the ', is a bamboo lemur. It is endemic to the reed beds in and around Lac Alaotra, in northeast Madagascar. It is about long, with a similar length tail, and is a brownish-gray colour. It is the only bamboo lemur to live in and feed on Cyperus papyrus, 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 (''Hapalemur griseus''). 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". Taxonomy The classification of the'' bandro'' is disputed, with some classifying it as a subspecies of ''Hapalemur griseus'', while others see it as a separate species.

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 ...

Mass
Mass is an intrinsic property of a body. It was traditionally believed to be related to the quantity of matter in a physical body, until the discovery of the atom and particle physics. It was found that different atoms and different elementary particles, theoretically with the same amount of matter, have nonetheless different masses. Mass in modern physics has multiple definitions which are conceptually distinct, but physically equivalent. Mass can be experimentally defined as a measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied. The object's mass also determines the strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg). In physics, mass is not the same as weight, even though mass is often determined by measuring the object's weight using a spring scale, rather than balance scale comparing it directly with known masses. An object on the Moon would weigh le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
