Avodiré
''Turraeanthus africanus'' is a species of plant in the family Meliaceae, also known by the common names avodiré, apeya, engan, agbe, lusamba, wansenwa, African satinwood, and African white mahogany. Nomenclature Although the species epithet given by François Pellegrin in the first publication is ''africana'', it should be amended into masculine form, i.e. ''africanus'' per the ICN (ed. 2017, Art. 62.2 (c)): "Compounds ending in ''‑ceras, ‑dendron, ‑nema, ‑stigma, ‑stoma'', and other neuter words, are neuter. An exception is made for names ending in ''‑anthos'' (or ''‑anthus''), ''‑chilos'' (''‑chilus'' or ''‑cheilos''), and ''‑phykos'' (''‑phycos'' or ''‑phycus''), which ought to be neuter, because that is the gender of the Greek words άνθος, anthos, χείλος, cheilos, and φύκος, phykos, but are treated as masculine in accordance with tradition." Description The species is found in Angola, Benin, Cameroon, the Democratic Republic of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trees Of Africa
In botany, a tree is a perennial plant with an elongated Plant stem, stem, or trunk (botany), trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller Arecaceae, palms, Cyatheales, tree ferns, Musa (genus), bananas, and bamboos are also trees. Trees are not a Taxon, taxonomic group but include a variety of plant species that Convergent evolution, have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

IUCN Red List
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 provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baka (Cameroon And Gabon)
The Baka people, known in the Congo as Bayaka (''Bebayaka, Bebayaga, Bibaya''), are an ethnic group inhabiting the southeastern rain forests of Cameroon, northern Republic of the Congo, northern Gabon, and southwestern Central African Republic. They are sometimes called a subgroup of the Twa, but the two peoples are not closely related. Likewise, the name "Baka" is sometimes mistakenly applied to other peoples of the area who, like the Baka and Twa, have been historically called pygmies, a term that is now considered derogatory. Identity Baka people are all hunter-gatherers, formerly referred to as pygmies, located in the Central African rain forest. Having average heights of 1.52 meters (5 feet) on average as well as living semi-nomadic lifestyles, the Baka are often discriminated against and marginalized from society. They reside in southeastern Cameroon, northern Gabon and in the northern part of the Republic of Congo. In Congo, the Baka people are otherwise known as the ...

Marquetry
Marquetry (also spelled as marqueterie; from the French ''marqueter'', to variegate) is the art and craft of applying pieces of veneer to a structure to form decorative patterns, designs or pictures. The technique may be applied to case furniture or even seat furniture, to decorative small objects with smooth, veneerable surfaces or to freestanding pictorial panels appreciated in their own right. Marquetry differs from the more ancient craft of inlay, or intarsia, in which a solid body of one material is cut out to receive sections of another to form the surface pattern. The word derives from a Middle French word meaning "inlaid work". Materials The veneers used are primarily woods, but may include bone, ivory, turtle-shell (conventionally called "tortoiseshell"), mother-of-pearl, pewter, brass or fine metals. Marquetry using colored straw was a specialty of some European spa resorts from the end of the 18th century. Many exotic woods as well as common European varieties ...

Panelling
Panelling (or paneling in the U.S.) is a millwork wall covering constructed from rigid or semi-rigid components. These are traditionally interlocking wood, but could be plastic or other materials. Panelling was developed in antiquity to make rooms in stone buildings more comfortable both by insulating the room from the stone, and reflecting radiant heat from wood fires, making heat more evenly distributed in the room. In more modern buildings, such panelling is often installed for decorative purposes. Panelling, such as wainscoting and boiserie in particular, may be extremely ornate and is particularly associated with 17th and 18th century interior design, Victorian architecture in Britain, and its international contemporaries. Wainscot panelling The term wainscot ( or ) originally applied to high quality riven oak boards. Wainscot oak came from large, slow-grown forest trees, and produced boards that were knot-free, low in tannin, light in weight, and easy to work wit ...

Wood Veneer
In woodworking, veneer refers to thin slices of wood and sometimes bark, usually thinner than 3 mm (1/8 inch), that typically are glued onto core panels (typically, wood, particle board or medium-density fiberboard) to produce flat panels such as doors, tops and panels for cabinets, parquet floors and parts of furniture. They are also used in marquetry. Plywood consists of three or more layers of veneer. Normally, each is glued with its grain at right angles to adjacent layers for strength. Veneer beading is a thin layer of decorative edging placed around objects, such as jewelry boxes. Veneer is also used to replace decorative papers in Wood Veneer HPL. Background Veneer is obtained either by "peeling" the trunk of a tree or by slicing large rectangular blocks of wood known as flitches. The appearance of the grain and figure in wood comes from slicing through the growth rings of a tree and depends upon the angle at which the wood is sliced. There are three main types ...

Mottle
Mottle is a pattern of irregular marks, spots, streaks, blotches or patches of different shades or colours. It is commonly used to describe the surface of plants or the skin of animals. In plants, mottling usually consists of yellowish spots on plants, and is usually a sign of disease or malnutrition. Many plant viruses cause mottling, some examples being: * Tobacco vein mottling virus * Bean pod mottle virus Mottling is sometimes used to describe uneven discolored patches on the skin of humans as a result of cutaneous ischemia (lowered blood flow to the surfaces of the skin) or Herpes zoster infections. The medical term for mottled skin is dyschromia. Although this is not always the case, mottling can occur in the dying patient and commonly indicates that the end of life is near. Mottling usually occurs in the extremities (lower first) and progresses up as cardiac function declines and circulation throughout the body is poor. In animals, mottling may be a sign of disease, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wood Grain
Wood grain is the longitudinal arrangement of wood fibers or the pattern resulting from such an arrangement. Definition and meanings R. Bruce Hoadley wrote that ''grain'' is a "confusingly versatile term" with numerous different uses, including the direction of the wood cells (e.g., ''straight grain'', ''spiral grain''), surface appearance or figure, growth-ring placement (e.g., ''vertical grain''), plane of the cut (e.g., ''end grain''), rate of growth (e.g., ''narrow grain''), and relative cell size (e.g., ''open grain'').Hoadley, R. Bruce. "Glossary." ''Understanding Wood: A Craftsman's Guide to Wood Technology''. Newtown, Conn.: Taunton, 1980. 265. Print. Physical aspects Perhaps the most important physical aspect of wood grain in woodworking is the grain direction or slope (e.g. against the grain). The two basic categories of grain are straight and cross grain. Straight grain runs parallel to the longitudinal axis of the piece. Cross grain deviates from the longitudinal a ...
