Isoberlinia Doka
''Isoberlinia doka'' is a hardwood tree native to African tropical savannas and Guinean forest-savanna mosaic dry forests where it can form single species stands. The tree is exploited for its economic value as a commercial timber. The leaves and shoots of the tree dominate the diet of the Giant Eland in its range. The tree is a host plant for '' Anaphe moloneyi'' (superfamily Thaumetopoeidae), one of the caterpillars that produces a wild silk Wild silks have been known and used in many countries from early times, although the scale of production is far smaller than that from cultivated silkworms.

Thaumetopoeidae
Thaumetopoeinae is a subfamily of moths in the family Notodontidae. This group is sometimes treated as a family Thaumetopoeidae with three subfamilies: Thaumetopoeinae, Anaphinae and Epicominae. However, it is now commonly treated at subfamily rank based on morphological and molecular phylogenetic evidence. The etymology of the subfamily name derives from the Ancient Greek words (, 'marvelous') and (, 'to do') and literally means ''showing beautiful things''. This explains why the name is sometimes spelled ''Thaumatopoeinae'', incorrectly from the taxonomic standpoint, but in accordance with etymology. The larval stage of some Thaumetopoeinae are known as processionary caterpillars, so named because they move in columns in search of food, resembling a procession. Some of the species, like the pine and oak processionaries, can constitute a health hazard due to their urticating hairs.

Flora Of Uganda
The wildlife of Uganda is composed of its flora and fauna. Uganda has a wide variety of different habitats, including mountains, hills, tropical rainforest, woodland, freshwater lakes, swamps and savanna with scattered clumps of trees. The country has a biodiverse flora and fauna reflecting this range of habitats and is known for its primates, including eastern gorilla, gorillas and eastern chimpanzee, chimpanzees. There are ten national parks and thirteen wildlife reserves; some 345 species of mammal and 1020 species of bird have been recorded in the country. Geography Uganda is a large country in East Africa lying on the equator. It is bounded by the Democratic Republic of the Congo to the west, South Sudan to the north, Kenya to the east and Rwanda and Tanzania to the south. Three large lakes, Lake Victoria, Lake Edward and Lake Albert (Africa), Lake Albert lie on the borders and Lake Kyoga lies in the centre. The country forms part of the Lake Victoria Basin and consists m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trees Of 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miombo
Miombo woodland is a tropical and subtropical grasslands, savannas, and shrublands biome (in the World Wide Fund for Nature scheme) located in central and southern tropical Africa. It includes three woodland savanna ecoregions (listed below) characterized by the dominant presence of '' Brachystegia'' and '' Julbernardia'' genera of trees, and has a range of climates ranging from humid to semi-arid, and tropical to subtropical or even temperate. The trees characteristically shed their leaves for a short period in the dry season to reduce water loss and produce a flush of new leaves just before the onset of the wet season with rich gold and red colours masking the underlying chlorophyll, reminiscent of autumn colours in the temperate zone. Miombo woodlands extend across south-central Africa, running from Angola in the west to Tanzania in the east, including parts of Democratic Republic of the Congo, Malawi, Mozambique, Zambia, and Zimbabwe. They are bounded on the north by the humid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Northeast Tropical 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.

Silk
Silk is a natural fiber, natural protein fiber, some forms of which can be weaving, woven into textiles. The protein fiber of silk is composed mainly of fibroin and is most commonly produced by certain insect larvae to form cocoon (silk), cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm ''Bombyx mori'' reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular Prism (optics), prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors. Harvested silk is produced by several insects; but, generally, only the silk of various moth caterpillars has been used for textile manufacturing. There has been some research into other types of silk, which differ at the molecular level. Silk is mainly produced by the larvae of insects undergoing holometabolism, complete metamorphosis, but some insects, such as webspinners and Gr ...

Wild Silk
Wild silks have been known and used in many countries from early times, although the scale of production is far smaller than that from cultivated silkworms. Silk cocoons and nests often resemble paper or cloth, and their use has arisen independently in many societies. Background Silk taken from various species has been used since ancient times, either in its natural state or after some form of preparation. Spider webs were used as a wound dressing in ancient Greece and Rome, and as a base for painting from the 16th century. Caterpillar nests were used to make containers and fabric in the Aztec Empire. To make a woven fabric, silk threads must first be either carded and spun, or extracted as a single intact thread. Commercially reared silkworms of the species ''Bombyx mori'' (Linnaeus, 1758) are normally killed before the pupae emerge, either by pricking them with a needle or dipping the cocoons into boiling water, thus allowing the whole cocoon to be unravelled as one contin ...
