Madagascan Fruit Bat
The Madagascan fruit bat (''Eidolon dupreanum'') is a species of bat in the family Pteropodidae. It is endemic to Madagascar and is listed as "Vulnerable" by the IUCN because it is hunted as bushmeat. Distribution and habitat ''Eidolon dupreanum'' is named after the Governor of Réunion from 1864 to 1869, Marie Jules Dupré, for the help he gave to scientific researchers. The Madagascan fruit bat is found both around the coastal plain and in the inland high plateau. It has not been recorded in some areas but that is likely to be because it has not been observed rather than that it is absent from these areas. It requires suitable rock fissures and caves in which to roost during the day. Colony size varies between about ten and five hundred individuals. Biology Examination of the droppings from the Madagascan fruit bat show that it mainly consumes fruit but also feeds on the flowers of ''Eucalyptus'' spp. It was found to fly as far as to reach trees of ''Polyscias'' spp. while la ...

Hermann Schlegel
Hermann Schlegel (10 June 1804 – 17 January 1884) was a German ornithologist, herpetologist and ichthyologist. Early life and education Schlegel was born at Altenburg, the son of a brassfounder. His father collected butterflies, which stimulated Schlegel's interest in natural history. The discovery, by chance, of a buzzard's nest led him to the study of birds, and a meeting with Christian Ludwig Brehm. Schlegel started to work for his father, but soon tired of it. He travelled to Vienna in 1824, where, at the university, he attended the lectures of Leopold Fitzinger and Johann Jacob Heckel. A letter of introduction from Brehm to gained him a position at the Naturhistorisches Museum. Ornithological career One year after his arrival, the director of this natural history museum, Carl Franz Anton Ritter von Schreibers, recommended him to Coenraad Jacob Temminck, director of the natural history museum of Leiden, who was seeking an assistant. At first Schlegel worked mainly o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adansonia Suarezensis
''Adansonia suarezensis'', the Suarez baobab, is an endangered species of ''Adansonia ''endemic to Madagascar. It is locally called "bozy" (pronounced "boojy"), the common name used for all baobabs in northern Madagascar.Baum, D.A., 1995, A Systematic Revision of Adansonia (Bombacaceae). Annals of the Missouri Botanical Garden , 1995, Vol. 82, No. 3 (1995), pp. 440-471 Description ''Adansonia suarezensis'' is a large tree up to tall, with a cylindrical trunk to in diameter. The bark is smooth and greyish-brown and a photosynthetic greenish layer can be seen underneath. The short, thick branches project horizontally from high on the trunk forming a horizontal crown. The leaves are palmate with 6 to 9 leaflets, yellowish-green, untoothed and deciduous. Large white flowers, drying to reddish brown, are produced after the leaves have fallen.

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 ...

Bushmeat
Bushmeat is meat from wildlife species that are hunted for human consumption, most often referring to the meat of game in Africa. Bushmeat represents a primary source of animal protein and a cash-earning commodity for inhabitants of humid tropical forest regions in Africa, Latin America and Asia. Bushmeat is an important food resource for poor people, particularly in rural areas. The numbers of animals killed and traded as bushmeat in the 1990s in West and Central Africa were thought to be unsustainable. By 2005, commercial harvesting and trading of bushmeat was considered a threat to biodiversity. As of 2016, 301 terrestrial mammals were threatened with extinction due to hunting for bushmeat including primates, even-toed ungulates, bats, diprotodont marsupials, rodents and carnivores occurring in developing countries. Bushmeat provides increased opportunity for transmission of several zoonotic viruses from animal hosts to humans, such as Ebolavirus and HIV. Nomenclature The ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide scie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollination
Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds, most often by an animal or by wind. Pollinating agents can be animals such as insects, birds, and bats; water; wind; and even plants themselves, when self-pollination occurs within a closed flower. Pollination often occurs within a species. When pollination occurs between species, it can produce hybrid offspring in nature and in plant breeding work. In angiosperms, after the pollen grain (gametophyte) has landed on the stigma, it germinates and develops a pollen tube which grows down the style until it reaches an ovary. Its two gametes travel down the tube to where the gametophyte(s) containing the female gametes are held within the carpel. After entering an ovum cell through the micropyle, one male nucleus fuses with the polar bodies to produce the endosperm tissues, while the other fuses with the ovule to produce the embr ...

Ceiba Pentandra
''Ceiba pentandra'' is a tropical tree of the order Malvales and the family Malvaceae (previously emplaced in the family Bombacaceae), native to Mexico, Central America and the Caribbean, northern South America, and (as the variety ''C. pentandra'' var ''guineensis'') West Africa. A somewhat smaller variety was introduced to South and Southeast Asia, where it is cultivated. The tree and the cotton-like fluff obtained from its seed pods are commonly known in English as kapok, a Malay-derived name which originally applied to ''Bombax ceiba'', a native of tropical Asia. In Spanish-speaking countries the tree is commonly known as "ceiba" and in French-speaking countries as fromager. The tree is cultivated for its cottonlike seed fibre, particularly in south-east Asia, and is also known as the Java cotton, Java kapok, silk-cotton or samauma. Characteristics The tree grows to as confirmed by climbing and tape drop with reports of Kapoks up to . These very large trees are in the N ...

François Pollen
François Paul Louis Pollen (1842–1886) was a Dutch naturalist and merchant. He made major contributions to the study of the Malagasy fauna. Biography Pollen was born on 8 January 1842 in Rotterdam, Netherlands. He had four siblings. His father M.P. Pollen (1806–1857) was owner of the distillery M.P. Pollen & Zoon in Rotterdam. In 1862, he moved to Leiden to study medicine, but Hermann Schlegel encouraged him to study zoology. Together with his companion Douwe Casparus van Dam (1827–1898) he made an expedition to Madagascar which lasted from November 1863 to July 1866. They collected insects, fish, birds, and mammals for the Rijksmuseum van Natuurlijke Historie in Leiden. Thanks to his wealth Pollen was able to finance this trip by himself. Subsequently, he also financed the field work of other naturalists on Madagascar without being directly involved. Further he collected animal and plant specimens on the Comoros and on the Mascarenes island of Réunion. In 1875 Pollen wa ...
