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] |
IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angraecum
The genus ''Angraecum'', abbreviated as Angcm in horticultural trade, common name comet orchid, contains about 220 species. Etymology Despite the genus's distribution being largely confined to Africa and its offshore islands, the genus name is a latinization of the Indonesian and Malay word anggrek (“orchid”), itself ultimately from Javanese ꦲꦔ꧀ꦒꦿꦺꦏ꧀ (anggrék, “orchid”). Description Angraecums are quite varied vegetatively and florally, and are adapted to dry tropical woodland habitat and have quite fleshy leaves as a consequence. Most are epiphytes, but a few are lithophytes. The long-lasting flowers are racemose and grow from the leaf axils. They are mostly white, but a few are yellow, green or ochre. They all have a long spur at the back of the labellum (lip). In the case of ''Angraecum sesquipedale'', a species from Madagascar, on observing the spur in the lip, Charles Darwin made the hypothesis that, since the nectar was at the bottom of the sp ...

Phorophyte
In botany phorophytes are plants, on which epiphyte An epiphyte is an organism that grows on the surface of a plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phoroph ...s grow. The term is composed of ''phoro'', meaning bearer or carrier and ''phyte'', meaning plant. Commensalistic interactions The epiphytes benefit from the habitats provided, but the phorophyte is unaffected. In other words, the obligate epiphytes utilize phorophytes as habitats, without parasitizing them.Sáyago, R., Lopezaraiza-Mikel, M., Quesada, M., Álvarez-Añorve, M. Y., Cascante-Marín, A., & Bastida, J. M. (2013). Evaluating factors that predict the structure of a commensalistic epiphyte–phorophyte network.

Klainedoxa Gabonensis
''Klainedoxa gabonensis'' is a large tropical African tree of the family Irvingiaceae growing to 40m in height. Its straight trunk is buttressed and up to 25m long, while its spreading evergreen crown makes it one of the largest trees of the rainforest. It is found from Senegal to Sudan, Cameroons, Ivory Coast, Democratic Republic of the Congo, Uganda and Tanzania, growing as far south as Angola and Zambia. The timber is dense (0.91-1.15) and extremely hard so that cutting and local usage is very limited, but trees are still exploited for firewood. Sapwood is thin, light brown in colour, and liable to insect attack. Heartwood is reddish to golden brown with wide dark veining, and zigzag markings. Poles are resistant to rotting and are used in hut construction and to make spring traps. This tree is usually left standing when forest is cleared for agriculture and forms a prominent part of the resultant landscape. Round about October the tree produces a spectacular flush of bright ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gilbertiodendron Dewevrei

Calamus (palm)
''Calamus'' is a genus of flowering plants in the palm family Arecaceae that are among several genera known as rattan palms. There are an estimated 400 species in this genus, all native to tropical and subtropical Asia, Africa, and Australia. Description They are dioecious, mostly leaf-climbing lianas with slender, reedy stems. To aid scrambling some species have evolved hooks on the underside of the midrib, or more commonly by modified "pinnae" or tendrils in the form of stout, backward-pointing spines. These stems may grow to lengths of 200 metres. The fruits of certain species, in particular ''Calamus draco'', produce a red resin known as "Dragon's blood".

Irvingia Smithii
''Irvingia'' is a genus of African and Southeast Asian trees in the family Irvingiaceae, sometimes known by the common names wild mango, African mango, bush mango, dika, mbukpap uyo or ogbono. They bear edible mango-like fruits, and are especially valued for their fat- and protein-rich nuts. The fruit is a large drupe, with fibrous flesh. The subtly aromatic nuts are typically dried in the sun for preservation, and are sold whole or in powder form. They may be ground to a paste known variously as dika bread or Gabon chocolate. Their high content of mucilage enables them to be used as thickening agents for dishes such as ogbono soup. The nuts may also be pressed for vegetable oil. The trees yield a hard wood, useful in construction. ''Irvingia'' was described as a genus in 1860. It is native to Africa and Southeast Asia. The genus is named in honour of Edward George Irving, a Royal Navy The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships ...
