Rhodesian Teak
''Baikiaea plurijuga'', known as African teak, Mukusi, Rhodesian teak, Zambian teak, or Zambesi redwood, is a species of Afrotropical tree from the legume family, the Fabaceae from southern Africa. The genus is named for William Balfour Baikie (1824-1864), a Scottish explorer of the Niger River, and the species name means "having many pairs." Description ''Baikiaea plurijuga'' is a medium-sized deciduous tree with pinnate leaves, each with 4-5 pairs of opposed leaflets. They show pink to deep mauve flowers, have yellow stamens, and are clustered in large axillary racemes; they flower from November to April. The fruit are flattened, woody pods with a hooked tip that splits explosively, sending the seeds out over some distance. Habitat ''Baikiaea plurijuga'' is confined to the Kalahari sands, and its dominant woodland is known as Gusu woodland. This woodland grows on the deep, aeolian, and fluvial Kalahari Sands, which have virtually no clay or silt. These sands provide exceptiona ...

Namibia
Namibia, officially the Republic of Namibia, is a country on the west coast of Southern Africa. Its borders include the Atlantic Ocean to the west, Angola and Zambia to the north, Botswana to the east and South Africa to the south; in the northeast, approximating a quadripoint, Zimbabwe lies less than 200 metres (660 feet) away along the Zambezi, Zambezi River near Kazungula, Zambia. Namibia's capital and largest city is Windhoek. Namibia is the driest country in sub-Saharan Africa, and has been inhabited since prehistoric times by the Khoekhoe, Khoi, San people, San, Damara people, Damara and Nama people. Around the 14th century, immigration, immigrating Bantu peoples arrived as part of the Bantu expansion. From 1600 the Ovambo people#History, Ovambo formed kingdoms, such as Ondonga and Oukwanyama. In 1884, the German Empire established rule over most of the territory, forming a colony known as German South West Africa. Between 1904 and 1908, German troops waged a punitive ...

Trees Of Southern Africa
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that 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 trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported clear of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Southern Africa
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...

Detarioideae
The subfamily Detarioideae is one of the subdivisions of the plant family Fabaceae (legumes). This subfamily includes many tropical trees, some of which are used for timber or have ecological importance. The subfamily consists of 84 genera, most of which are native to Africa and Asia. Pride of Burma (''Amherstia nobilis'') and tamarind (''Tamarindus indica'') are two of the most notable species in Detarioideae. It has the following clade-based definition: The most inclusive crown clade containing '' Goniorrhachis marginata'' Taub. and '' Aphanocalyx cynometroides'' Oliv., but not '' Cercis canadensis'' L., '' Duparquetia orchidacea'' Baill., or '' Bobgunnia fistuloides'' (Harms) J.

Baikiain
Baikiain is an organic compound with the molecular formula . Chemically, it is classified as a tetrahydropyridine substituted with a carboxylic acid. Because it contains both this carboxylic acid and an adjacent amine group, it is also an alpha-amino acid. Baikiain is one of the two enantiomers of the chiral compound 4,5-didehydropipecolic acid. Sources Baikiain has been found in diverse natural sources including dates, African teak African teak is a common name for several plants and may refer to: *'' Baikiaea plurijuga'', native to the northern Kalahari *'' Milicia excelsa'', also known as iroko, native to Africa from the Ivory Coast to Ethiopia and south to Angola and Moz ... (''Baikiaea plurijuga'') wood, and the red algae '' Serraticardia maxima''. Several laboratory syntheses of baikiain and its racemic form have been reported. Effects Baikiain is hypothesized to be the causative agent of illnesses resulting from consumption of food products containing tara flour. Re ...

Coppicing
Coppicing is the traditional method in woodland management of cutting down a tree to a tree stump, stump, which in many species encourages new Shoot (botany), shoots to grow from the stump or roots, thus ultimately regrowing the tree. A forest or grove that has been subject to coppicing is called a copse or coppice, in which young tree stems are repeatedly cut down to near ground level. The resulting living stumps are called Living stump, stools. New growth emerges, and after a number of years, the coppiced trees are harvested, and the cycle begins anew. Pollarding is a similar process carried out at a higher level on the tree in order to prevent grazing animals from eating new shoots. ''Daisugi'' (台杉, where ''sugi'' refers to Japanese cedar) is a similar Japanese technique. Many silviculture practices involve cutting and regrowth; coppicing has been of significance in many parts of lowland temperate Europe. The widespread and long-term practice of coppicing as a landscape ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Over-exploited
Overexploitation, also called overharvesting or ecological overshoot, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish. The term applies to natural resources such as water aquifers, grazing pastures and forests, wild medicinal plants, fish stocks and other wildlife. In ecology, overexploitation describes one of the five main activities threatening global biodiversity. Ecologists use the term to describe populations that are harvested at an unsustainable rate, given their natural rates of mortality and capacities for reproduction. This can result in extinction at the population level and even extinction of whole species. In conservation biology, the term is usually used in the context of human economic activity that involves the taking of biological resources, or organisms, in larger numbers than their populations can withstand. The term is als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Termite
Termites are a group of detritivore, detritophagous Eusociality, eusocial cockroaches which consume a variety of Detritus, decaying plant material, generally in the form of wood, Plant litter, leaf litter, and Humus, soil humus. They are distinguished by their moniliform antennae and the soft-bodied, unpigmented worker caste for which they have been commonly termed "white ants"; however, they are not ants but highly Apomorphy and synapomorphy, derived cockroaches. About 2,997 extant species are currently described, 2,125 of which are members of the family Termitidae. Termites comprise the infraorder Isoptera, or alternatively the Taxonomic rank#All ranks, epifamily Termitoidae, within the order Blattodea (the cockroaches). Termites were once classified in a separate Order (biology), order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are deeply nested within the group, and the sister group to wood-eating cockroaches of t ...
