Apocynaceae
Apocynaceae (from ''Apocynum'', Greek for "dog-away") is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae (now known as Asclepiadoideae) is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here. Many species are tall trees found in tropical forests, but some grow in tropical dry (xeric) environments. Also perennial herbs from temperate zones occur. Many of these plants have milky latex, and many species are poisonous if ingested, the family being rich in genera containing alkaloids and cardiac glycosides, those containing the latter often finding use as arrow poisons. Some genera of Apocynaceae, such as '' Adenium'', bleed clea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buttress Root
Buttress roots also known as plank roots are large, wide roots on all sides of a shallowly rooted tree. Typically, they are found in nutrient-poor tropical forest soils that may not be very deep. They prevent the tree from falling over (hence the name buttress) while also gathering more nutrients. Buttresses are tension elements, being larger on the side away from the stress of asymmetrical canopies. The roots may intertwine with buttress roots from other trees and create an intricate mesh, which may help support trees surrounding it. They can grow up to tall and spread for 30 metres above the soil then for another 30 metres below. When the roots spread horizontally, they are able to cover a wider area for collecting nutrients. They stay near the upper soil layer because all the main nutrients are found there. Buttress roots vary greatly in size from barely discernable to many square yards (square meters) of surface. The largest for which there is photographic evidence is a More ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lower Guinean Forests
The Lower Guinean forests is region of coastal tropical moist broadleaf forest in West Africa, extending along the eastern coast of the Gulf of Guinea from eastern Benin through Nigeria and Cameroon. The Dahomey Gap, a region of savanna and dry forest in Togo and Benin, divides the Lower Guinean forests from the Upper Guinean forests to the west, which extend along the western coast of the Gulf of Guinea from Togo to Liberia and north to Guinea. To the north and northeast, the Lower Guinean forests transition to the drier inland Guinean forest–savanna mosaic and Northern Congolian forest–savanna mosaic and to the southeast by the Congolian Coastal forests, whose boundary is the Sanaga River in Cameroon.Linder, H. Peter, Helen M. de Klerk Julia Born et al. (2012). "The partitioning of Africa: statistically defined biogeographical regions in sub‐Saharan Africa".

Upper Guinean Forests
The Upper Guinean forests is a tropical seasonal forest region of West Africa. The Upper Guinean forests extend from Guinea and Sierra Leone in the west through Liberia, Côte d'Ivoire and Ghana to Togo in the east, and a few hundred kilometers inland from the Atlantic coast. A few enclaves of montane forest lie further inland in the mountains of central Guinea and central Togo and Benin. In the drier interior, the Upper Guinean forests yield to the Guinean forest-savanna mosaic, a belt of dry forests and savannas that lies between the coastal forests and the savannas and grasslands of the Sudan further north. The Dahomey Gap, a region of Togo and Benin where the Guinean forest-savanna mosaic extends to the Atlantic coast, separates the Upper Guinean forests from the Lower Guinean forests to the east, which extend from eastern Benin through Nigeria, Cameroon, and south along the coast of the Gulf of Guinea. The Upper Guinean forests are a Global 200 ecoregion. The Guinean moist fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latex
Latex is an emulsion (stable dispersion) of polymer microparticles in water. Latexes are found in nature, but synthetic latexes are common as well. In nature, latex is found as a milky fluid found in 10% of all flowering plants (angiosperms). It is a complex emulsion that coagulates on exposure to air, consisting of proteins, alkaloids, starches, sugars, oils, tannins, resins, and gums. It is usually exuded after tissue injury. In most plants, latex is white, but some have yellow, orange, or scarlet latex. Since the 17th century, latex has been used as a term for the fluid substance in plants, deriving from the Latin word for "liquid". It serves mainly as defense against herbivorous insects. Latex is not to be confused with plant sap; it is a distinct substance, separately produced, and with different functions. The word latex is also used to refer to natural latex rubber, particularly non-vulcanized rubber. Such is the case in products like latex gloves, latex condoms ...

Guere Language
Guéré (Gere), also called Wè (Wee), is a Kru languages, Kru language spoken by over 300,000 people in the Dix-Huit Montagnes and Moyen-Cavally regions of Ivory Coast. Phonology The phonology of Guere (here the Zagna dialect of Central Guere / Southern Wè) is briefly sketched out below. Consonants The consonant phonemes are as follows: Allophones of some of these phonemes include: * is an allophone of before nasal vowels * is an allophone of before nasal vowels * is an allophone of before nasal vowels * is an allophone of in word-initial position * is an allophone of after a coronal consonant (alveolar or palatal) In addition, while the nasal consonants and contrast with and before oral vowels, and are thus separate phonemes, before nasal vowels only the nasal consonants occur. and do not occur before nasal vowels, suggesting that historically a Phonemic differentiation, phonemic merger between these sounds and the nasals may have occurred in this position. ...

Birdlime
Birdlime or bird lime is an adhesive substance used in trapping birds. It is spread on a branch or twig, upon which a bird may land and be caught. Its use is illegal in many jurisdictions. Manufacture Historically, the substance has been prepared in various ways, and from various materials. In South Africa, birdlime (called ''voëlent'' in Afrikaans) is prepared from mistletoe fruits. A handful of ripe fruits is chewed until sticky, and the mass is then rubbed between the palms of the hands to form long and extremely sticky strands which are then coiled around small thin tree branches where birds perch. A popular form in Europe was made from holly bark, boiled for 10 to 12 hours. After the green coating is separated from the other, it is stored in a moist place for two weeks. It is then pounded into a thick paste, until no wood fibres remain, and washed in running water until no small specks appear. After fermenting for four or five days, during which it is frequently skimmed, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Mozambique
The wildlife of Mozambique consists of the flora and fauna of this country in southeastern Africa. Mozambique has a range of different habitat types and an ecologically rich and diverse wildlife. This includes 236 species of mammal, 740 species of bird and 5,692 species of vascular plant. The Maputaland-Pondoland-Albany hotspot, with significantly high levels of biodiversity, stretches from the southern tip of Mozambique into northeastern South Africa.

It is bounded by Eswatini to the south, South Africa to the south and southwest, Zimbabwe to the west, Zambia and Malawi to the northwest, Tanzania to the north and the Indian Ocean to the east. Mozambique lies between latitudes 10° and 27°S, and longitudes 30° and 41°E. The country is divided into two topographical regions by the Zambezi River. To the north of the Zambezi, the narrow coastal strip gives way to inland hills and low plateaus. Rugged highland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of West Tropical Africa
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. 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) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
