Eastern Lesser Bamboo Lemur
The eastern lesser bamboo lemur (''Hapalemur griseus''), also known as the gray bamboo lemur, the gray gentle lemur, and the Mahajanga lemur is a small lemur endemic to Madagascar, with three known subspecies. As its name suggests, the eastern lesser bamboo lemur feeds mainly on bamboo. The lemurs of the genus ''Hapalemur'' have more manual dexterity and hand–eye coordination than most lemurs. They are vertical climbers and jump from stalk to stalk in thick bamboo forests. Subspecies Eastern lesser bamboo lemur The eastern lesser bamboo lemur (''Hapalemur griseus griseus''), also known as the gray bamboo lemur, eastern gray bamboo lemur, or gray gentle lemur, was the original species described in 1795 by Johann Heinrich Friedrich Link. It is grey in colour, sometimes with a red patch on its head. It averages in length with a tail of . Based on data from more than one hundred transect surveys which took place between 2004 and 2009, the population is estimated to be declining ...

Johann Heinrich Friedrich Link
Johann Heinrich Friedrich Link (2 February 1767 – 1 January 1851) was a German naturalist and botanist. Biography Link was born at Hildesheim as a son of the minister August Heinrich Link (1738–1783), who taught him love of nature through collection of 'natural objects'. He studied medicine and natural sciences at the Hannoverschen Landesuniversität of Göttingen, and graduated as MD in 1789, promoting on his thesis ''"Flora der Felsgesteine rund um Göttingen"'' (Flora of the rocky beds around Göttingen). One of his teachers was the famous natural scientist Johann Friedrich Blumenbach (1752–1840). He became a private tutor (''Privatdozent'') in Göttingen. In 1792 he became the first professor of the new department of chemistry, zoology and botany at the University of Rostock. During his stay at Rostock, he became an early follower of the antiphlogistic theory of Lavoisier, teaching about the existence of oxygen instead of phlogiston. He was also a proponent of the ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Described In 1795
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with ...

Bamboo Lemurs
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 seconds) ...

Betsiboka River
Betsiboka River is a long river in central-north Madagascar. It flows northwestward and empties to Bombetoka Bay, forming a large river delta, delta. It originates to the east of Antananarivo. The river is surrounded in mangroves. The river is distinctive for its red-coloured water, which is caused by river sediments. The river carries an enormous amount of reddish-orange silt to the sea. Much of this silt is deposited at the mouth of the river or in the bay. It is dramatic evidence of the catastrophic erosion of northwestern Madagascar. Removal of the native forest for cultivation and pastureland during the past 50 years has led to massive annual soil losses approaching 250 metric tonnes per hectare (112 tons per acre) in some regions of the island, the largest amount recorded anywhere in the world. Several fish species are Endemism, endemic to the river basin, including the three cichlids ''Kotso, Paretroplus petiti'', ''Paretroplus tsimoly, P. tsimoly'' and ''Damba mipentina, P ...

Tsingy De Bemaraha Strict Nature Reserve
Tsingy de Bemaraha Strict Nature Reserve is a nature reserve located near the western coast of Madagascar in Melaky Region at . The area was listed as a UNESCO World Heritage Site in 1990 due to the unique geography, preserved mangrove forests, and wild bird and lemur populations. National Park The southern end of the protected area has subsequently been changed into the Tsingy de Bemaraha National Park, covering . The northern end of the protected area remains as a strict nature reserve (Réserve Naturelle Intégrale) covering . It is characterised by needle-shaped limestone formations, above cliffs over the Manambolo River. The incredibly sharp limestone formations can cut through equipment and flesh easily, which makes traversing them extremely difficult. The word "Tsingy" is derived from a local word meaning "the place where one cannot walk barefoot". Tourism Tourists can access the national park by road from Morondava, a town 150 km south of the park. Limited access ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Deficient
A data deficient (DD) species is one which has been categorized by the International Union for Conservation of Nature (IUCN) as offering insufficient information for a proper assessment of conservation status to be made. This does not necessarily indicate that the species has not been extensively studied; but it does indicate that little or no information is available on the abundance and distribution of the species. The IUCN recommends that care be taken to avoid classing species as "data deficient" when the absence of records may indicate dangerously low abundance: "If the range of a taxon is suspected to be relatively circumscribed, if a considerable period of time has elapsed since the last record of the taxon, threatened status may well be justified""The Categories," in IUCN (1983). (see also precautionary principle). See also * IUCN Red List data deficient species * List of data deficient amphibians * IUCN Red List data deficient species (Annelida) * List of data deficien ...
