Lac Alaotra Bamboo 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 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. Current genetic data do not support species sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Alaotra
Lake Alaotra ( mg, farihin' Alaotra, ; french: Lac Alaotra) is the largest lake in Madagascar, located in Alaotra-Mangoro, 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 , and include a range of habitats, including open water, reedbeds, marshes, and rice paddies. The lake itself covers . Lake Alaotra was declared a Ramsar List of Wetlands of International Importance, wetland of international importance under the international Ramsar Convention on February 2, 2003. The Oreochromis macrochir, longfin tilapia (''Oreochromis macrochir'') was introduced into Lake Alaotra from the mainland in 1954 and proliferated quickly. By 1957 ...

Hapalemur Griseus
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 ...

Mammals Of Madagascar
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 Sauropsida ...

Endemic Fauna Of Madagascar
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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) ...

Captive Breeding
Captive breeding, also known as captive propagation, is the process of plants or animals in controlled environments, such as wildlife reserves, zoos, botanic gardens, and other conservation facilities. It is sometimes employed to help species that are being threatened by the effects of human activities such as climate change, habitat loss, fragmentation, over hunting or fishing, pollution, predation, disease, and parasitism. For many species, relatively little is known about the conditions needed for successful breeding. Information about a species' reproductive biology may be critical to the success of a captive breeding program. In some cases a captive breeding program can save a species from extinction, but for success, breeders must consider many factors—including genetic, ecological, behavioral, and ethical issues. Most successful attempts involve the cooperation and coordination of many institutions. History Captive breeding techniques began with the first human do ...

Durrell Wildlife Conservation Trust
Durrell Wildlife Conservation Trust is a conservation organization with a mission to save species from extinction. Gerald Durrell founded the Jersey Wildlife Preservation Trust as a charitable institution in 1963 with the dodo as its symbol. The trust was renamed Durrell Wildlife Conservation Trust in its founder's honor on 26 March 1999. Its patron is Princess Anne, the Princess Royal. Its headquarters are at Les Augrès Manor on the isle of Jersey in the English Channel. The grounds of Les Augrès Manor form the Durrell Wildlife Park, which was originally established by Gerald Durrell in 1959 as a sanctuary and breeding center for endangered species. The zoological park was known as the ''Jersey Zoo'' at that time. As of 2016, the zoo was home to more than one hundred species of reptiles, birds and mammals, many of which are designated as endangered in the wild. Despite strong resistance to his ideas from much of the zoological community, in 1959 Gerald Durrell succeeded in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Echinochloa Crus-galli
''Echinochloa crus-galli'' is a type of wild grass originating from tropical Asia that was formerly classified as a type of panicum grass. It is commonly known as cockspur (or cockspur grass), barnyard millet, Japanese millet, water grass, common barnyard grass, or simply "barnyard grass" (which may refer to any species of ''Echinochloa'' or the genus as a whole however). This plant can grow to 60" (1.5 m) in height and has long, flat leaves which are often purplish at the base. Most stems are upright, but some will spread out over the ground. Stems are flattened at the base. The seed heads are a distinctive feature, often purplish, with large millet-like seeds in crowded spikelets. Considered one of the world's worst weeds, it reduces crop yields and causes forage crops to fail by removing up to 80% of the available soil nitrogen. It acts as a host for several mosaic virus diseases.Heuzé V., Thiollet H., Tran G., Lebas F., 2017. Cockspur grass (Echinochloa crus-galli) forage. Fe ...

Phragmites Communis
''Phragmites australis'', known as the common reed, is a species of plant. It is a broadly distributed wetland grass that can grow up to tall. Description ''Phragmites australis'' commonly forms extensive stands (known as reed beds), which may be as much as or more in extent. Where conditions are suitable it can also spread at or more per year by horizontal runners, which put down roots at regular intervals. It can grow in damp ground, in standing water up to or so deep, or even as a floating mat. The erect stems grow to tall, with the tallest plants growing in areas with hot summers and fertile growing conditions. The leaves are long and broad. The flowers are produced in late summer in a dense, dark purple panicle, about long. Later the numerous long, narrow, sharp pointed spikelets appear greyer due to the growth of long, silky hairs. These eventually help disperse the minute seeds. Taxonomy Recent studies have characterized morphological distinctions between the int ...

Papyrus
Papyrus ( ) is a material similar to thick paper that was used in ancient times as a writing surface. It was made from the pith of the papyrus plant, '' Cyperus papyrus'', a wetland sedge. ''Papyrus'' (plural: ''papyri'') can also refer to a document written on sheets of such material, joined side by side and rolled up into a scroll, an early form of a book. Papyrus is first known to have been used in Egypt (at least as far back as the First Dynasty), as the papyrus plant was once abundant across the Nile Delta. It was also used throughout the Mediterranean region. Apart from a writing material, ancient Egyptians employed papyrus in the construction of other artifacts, such as reed boats, mats, rope, sandals, and baskets. History Papyrus was first manufactured in Egypt as far back as the fourth millennium BCE.H. Idris Bell and T.C. Skeat, 1935"Papyrus and its uses"(British Museum pamphlet). The earliest archaeological evidence of papyrus was excavated in 2012 and 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
