The IUCN 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 sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Didiereaceae
Didiereaceae is a family of flowering plants found in continental Africa and Madagascar. It contains 20 species classified in three subfamilies and six genera. Species of the family are succulent plants, growing in sub-arid to arid habitats. Several are known as ornamental plants in specialist succulent collections. The subfamily Didiereoideae is endemic to the southwest of Madagascar, where the species are characteristic elements of the spiny thickets. Systematics The family was long considered entirely endemic to Madagascar until the genera ''Calyptrotheca'', ''Ceraria'', and ''Portulacaria'' from the African mainland were included. Molecular phylogenetic analysis confirmed the monophyly of the family and its three subfamilies: The family is closely related to the New World family Cactaceae (cacti), sufficiently closely so that species of Didiereaceae can be grafted successfully on some cacti. Calyptrothecoideae Contains only one genus, ''Calyptrotheca'', with two specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Verreaux's Sifaka
Verreaux's sifaka (''Propithecus verreauxi''), or the white sifaka, is a medium-sized primate in one of the lemur families, the Indriidae. It lives in Madagascar and can be found in a variety of habitats from rainforest to dry deciduous forests of western Madagascar and the spiny thickets of the south. Its fur is thick and silky and generally white with brown on the sides, top of the head, and on the arms. Like all sifakas, it has a long tail that it uses as a balance when leaping from tree to tree. However, its body is so highly adapted to an arboreal existence, on the ground its only means of locomotion is hopping. The species lives in small troops which forage for food. Anatomy In adulthood, the full head and body length is between . The tail of a fully grown Verreaux's sifaka grows to be between long. In weight, adult females reach on average, and adult males . Verreaux's sifaka has a relatively low, flat braincase. The face is broader than that of most other indriids, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Commiphora Aprevalii
''Commiphora aprevalii'', known locally as the Vazaha tree, is a member of the Burseraceae family endemic to Madagascar. In Malagasy, "Vazaha" means stranger or foreigner; the name likens the characteristic peeling bark to the peeling skin of a badly sunburnt tourist. The Vazaha tree is a deciduous succulent, which tolerates dry season conditions by shedding its leaves and storing water in its trunk and branches. The peeling bark is thought to help the trunk and branches photosynthesize. The leaves of ''C. aprevalii'' are pinnate with lanceolate leaflets. The species is a close relative of the myrrh tree, ''Commiphora myrrha''. The species was named after André Revillon d'Apreval, a French botanical illustrator active at the turn of the twentieth century. Another member of the Burseraceae family from across the world, the gumbo-limbo ''Bursera simaruba'', commonly known as gumbo-limbo, copperwood, chaca, West Indian birch, naked Indian, and turpentine tree, is a tree sp ...

Operculicarya Decaryi
''Operculicarya decaryi'', known as elephant tree or jabily, is a thick stemmed succulent plant species in the family Anacardiaceae, named after the botanical collector Raymond Decary. It is found in Madagascar and is also grown as a bonsai tree. It has small (less than 2 mm) red flowers in winter. The inflorescence is at the end of short branches and often consist of about five flowers. Woody cuttings need a soil mixture kept uniformly moist for propagation. It can also be propagated using pieces of the tuberous Tubers are a type of enlarged structure used as storage organs for nutrients in some plants.

Alluaudia Procera
''Alluaudia procera'', or Madagascar ocotillo, is a deciduous succulent plant species of the family Didiereaceae. It is endemic to south Madagascar. Description This plant is a spiny succulent shrub, with thick water-storing stems and leaves that are deciduous in the long dry season. Although strikingly similar in appearance, it is not closely related to the ocotillo, '' Fouquieria splendens'' of the Sonoran Deserts in North America. Young alluaudias form a tangle of stems that last for several years, after which a strong central stem develops. The basal stems then die out, leaving a tree-like stem that branches higher up on the main trunk. Like other members of family Didiereaceae, the leaves of ''Alluaudia'', produced from brachyblasts similar to the areoles found in cacti, are small, appear single and are accompanied with conical spines. Its flowers are unisexual and radially symmetric. Taxonomy The Didiereaceae comprise 11 species divided into 4 genera, of which the la ...

Madagascar Spiny Thickets
The Madagascar spiny forests (also known as the Madagascar spiny thickets) is an ecoregion in the southwest of Madagascar. The vegetation type is found on poor substrates with low, erratic winter rainfall. The ecoregion contains an outstanding proportion of endemic plant species and is listed as one of the 200 most important ecological regions in the world; one of the Global 200. Flora This is the area with the highest level of plant endemism in Madagascar, with 48% of the genera and 95% of the species endemic.Elmqvist T, Pyyko ̈nen M, Tengo ̈M, Rakotondrasoa F, Rabakonandrianina E, et al (2007) Patterns of Loss and Regeneration of Tropical DryForest in Madagascar: The Social Institutional Context.

Emmanuel Drake Del Castillo
Emmanuel Drake del Castillo (28 December 1855 – 14 May 1904) was a French botanist. He was born at Paris and studied with Louis Édouard Bureau (1830–1918) at the Muséum national d'histoire naturelle (National Museum of Natural History). Between 1886 and 1892, he published ''Illustrationes Florae Insulae Maris Pacifici'' ("Illustrations of the flora of the islands of the Pacific Ocean") a summarization of his work on the flora of French Polynesia. He also studied the flora of Madagascar. In addition, he put together a herbarium which contained more than 500,000 samples. He died in 1904 at Saint-Cyran-du-Jambot, bequeathing his herbarium to the Muséum national d'histoire naturelle. Taxa He was the taxonomic authority of numerous plants. The following is a list of botanical genera that he described: * ''Alluaudia'', family Didiereaceae * '' Apaloxylon'', family Leguminosae * '' Bathiaea'', family Leguminosae * ''Cullumiopsis'', family Asteraceae (now classed a sy ...

Area Of Occupancy
Area is the quantity that expresses the extent of a region on the plane or on a curved surface. The area of a plane region or ''plane area'' refers to the area of a shape or planar lamina, while '' surface area'' refers to the area of an open surface or the boundary of a three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analogue of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept). The area of a shape can be measured by comparing the shape to squares of a fixed size. In the International System of Units (SI), the standard unit of area is the square metre (written as m2), which is the area of a square whose sides are one metre long. A shape with an area of three square metres would have the same area as three such squares. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
