East Saharan Montane Xeric Woodlands
The East Saharan montane xeric woodlands is an ecoregion of central Africa, a number of high mountains in the middle of the huge area of savanna on the edge of the Sahara Desert. Location and description The ecoregion covers the higher elevations of the Ennedi Plateau and the Ouaddaï Highlands of eastern Chad and the extinct volcano system Jebel Marra in Darfur, western Sudan. These mountain ranges rise above the semi-desert sahelian Acacia savanna at the southern edge of the Sahara Desert. The ecoregion covers an area of . The summer rains are irregular, even more so in Chad than on Jebel Marra, which has two crater lakes. Flora Plant life includes many species typical of the sahel belt including ''Ammania gracilis'', the grass ''Panicum laetum'', the forb '' Chrozophora brocchiana'' and the herbs '' Farsetia stenoptera'', ''Indigofera senegalensis'' and ''Tephrosia gracilipes''. One classic element of the natural flora was Laperrine's Olive ''(Olea europaea laperrinei)' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afrotropical Realm
The Afrotropical realm is one of Earth's eight biogeographic realms. It includes Africa south of the Sahara Desert, the majority of the Arabian Peninsula, the island of Madagascar, southern Iran and extreme southwestern Pakistan, and the islands of the western Indian Ocean. It was formerly known as the Ethiopian Zone or Ethiopian Region. Major ecological regions Most of the Afrotropic, with the exception of Africa's southern tip, has a tropical climate. A broad belt of deserts, including the Atlantic and Sahara deserts of northern Africa and the Arabian Desert of the Arabian Peninsula, separate the Afrotropic from the Palearctic realm, which includes northern Africa and temperate Eurasia. Sahel and Sudan South of the Sahara, two belts of tropical grassland and savanna run east and west across the continent, from the Atlantic Ocean to the Ethiopian Highlands. Immediately south of the Sahara lies the Sahel belt, a transitional zone of semi-arid short grassland and vachellia sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forb
A forb or phorb is an herbaceous flowering plant that is not a graminoid (grass, sedge, or rush). The term is used in biology and in vegetation ecology, especially in relation to grasslands and understory. Typically these are dicots without woody stems. Etymology The word "forb" is derived from Greek ''phorbḗ'' (), meaning "pasture" or "fodder". The Hellenic spelling "phorb" is sometimes used, and in older usage this sometimes includes graminids and other plants currently not regarded as forbs. Guilds Forbs are members of a guilda group of plant species with broadly similar growth form. In certain contexts in ecology, guild membership may often be more important than the taxonomic relationships between organisms. In informal classification In addition to its use in ecology, the term "forb" may be used for subdividing popular guides to wildflowers, distinguishing them from other categories such as grasses, sedges, shrubs, and trees. Some examples of forbs are clovers, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neotis Nuba
The Nubian bustard (''Neotis nuba'') is a species of bird in the bustard family. This is a medium-large bustard found in the sparsely vegetated interface between the southern margins of the Sahara desert and the northern part of the Sahel. It is found in Burkina Faso, Cameroon, Chad, Mali, Mauritania, Niger, Nigeria, and Sudan. Its natural habitats are dry savanna and subtropical or tropical dry shrubland. Description In this species, males average around and measure around in length and in wingspan. Females are much smaller at around and in length and across the wings.Beaman & Madge, ''The Handbook of Bird Identification for Europe and the Western Palearctic''. Princeton University Press (1998), It is smaller than the sympatric Arabian bustard, as well as more rufous with a different body shape. Compared to larger bustards the Nubian has a more rounded body, a relatively long, thin neck and a rounded head. Life history Observation of breeding has occurred from July to Oct ...

Red-fronted Gazelle
The red-fronted gazelle (''Eudorcas rufifrons'') is widely but unevenly distributed gazelle across the middle of Africa from Senegal to northeastern Ethiopia. It is mainly resident in the Sahel zone, a narrow cross-Africa band south of the Sahara, where it prefers arid grasslands, wooded savannas and shrubby steppes. One authority considers Thomson's gazelle (''E. thomsoni''), of East Africa, a subspecies of red-fronted gazelle. The red-fronted gazelle was formerly considered a member of the genus ''Gazella'' within the subgenus ''Eudorcas'' before ''Eudorcas'' was elevated to generic status. Taxonomy The scientific name of the red-fronted gazelle is ''Eudorcas rufifrons''. It was first described by British zoologist John Edward Gray. * ''Eudorcas rufifrons centralis'' W. Schwarz, 1914 – eastern Chad red-fronted gazelle * ''E. r. hasleri'' Pocock, 1912 – north Nigeria red-fronted gazelle. * ''E. r. kanuri'' Schwarz, 1914 – Kanuri red-fronted gazelle * ''E. r. laevipes'' Su ...

Dorcas Gazelle
The dorcas gazelle (''Gazella dorcas''), also known as the ariel gazelle, is a small and common gazelle. The dorcas gazelle stands about at the shoulder, with a head and body length of and a weight of . The numerous subspecies survive on vegetation in grassland, steppe, wadis, mountain desert and in semidesert climates of Africa and Arabia. About 35,000–40,000 exist in the wild. Taxonomy and evolution The scientific name of the dorcas gazelle is ''Gazella dorcas''. It is a member of the genus ''Gazella'' and the family Bovidae. The species was first described by Swedish zoologist Carl Linnaeus in the 10th edition of ''Systema Naturae'' in 1758. Although zoologist Theodor Haltenorth considered ''G. d. pelzelnii'' to be an independent species, the following six subspecies are identified: *''G. d.'' subsp. ''beccarii'' De Beaux, 1931 – Eritrean dorcas gazelle *''G. d.'' subsp. ''dorcas'' (Linnaeus, 1758) – Egyptian dorcas gazelle *''G. d.'' subsp. ''isabella'' Gray, ...

Dama Gazelle
The dama gazelle (''Nanger dama''), also known as the addra gazelle or mhorr gazelle, is a species of gazelle. It lives in Africa, in the Sahara desert and the Sahel. A critically endangered species, it has disappeared from most of its former range due to overhunting and habitat loss, and natural populations only remain in Chad, Mali, and Niger. Its habitat includes grassland, shrubland, semi-deserts, open savanna and mountain plateaus. Its diet includes grasses, leaves (especially ''Acacia'' leaves), shoots, and fruit. In Niger, the dama gazelle has become a national symbol. Under the Hausa name or , the dama gazelle appears on the badge of the Niger national football team, who are popularly called the ''Ménas''. Description The dama gazelle is white with a reddish-brown head and neck. Both sexes usually have medium-length ringed horns curved like an "S". Males' horns are about long, while females' horns are much shorter. The head is small with a narrow muzzle, and the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Addax
The addax (''Addax nasomaculatus''), also known as the white antelope and the screwhorn antelope, is an antelope native to the Sahara Desert. The only member of the genus ''Addax'', it was first described scientifically by Henri de Blainville in 1816. As suggested by its alternative name, the pale antelope has long, twisted horns – typically in females and in males. Males stand from at the shoulder, with females at . They are sexually dimorphic, as the females are smaller than the males. The colour of the coat depends on the season – in the winter, it is greyish-brown with white hindquarters and legs, and long, brown hair on the head, neck, and shoulders; in the summer, the coat turns almost completely white or sandy blonde. The addax mainly eats grasses and leaves of any available shrubs, leguminous herbs and bushes. They are well-adapted to exist in their desert habitat, as they can live without water for long periods of time. Addax form herds of five to 20 members, ...

Antelope
The term antelope is used to refer to many species of even-toed ruminant that are indigenous to various regions in Africa and Eurasia. Antelope comprise a wastebasket taxon defined as any of numerous Old World grazing and browsing hoofed mammals belonging to the family Bovidae of the order Artiodactyla. A stricter definition, also known as the "true antelopes," includes only the genera ''Gazella'', ''Nanger'', ''Eudorcas'' and ''Antilope''. One North American species, the pronghorn, is colloquially referred to as the "American antelope," but it belongs to a different family from the African and Eurasian antelopes. A group of antelope is called a herd. Unlike deer antlers, which are shed and grown annually, antelope horns grow continuously. Etymology The English word "antelope" first appeared in 1417 and is derived from the Old French ''antelop'', itself derived from Medieval Latin ''ant(h)alopus'', which in turn comes from the Byzantine Greek word ἀνθόλοψ, ''anthó ...

Olive
The olive, botanical name ''Olea europaea'', meaning 'European olive' in Latin, is a species of small tree or shrub in the family Oleaceae, found traditionally in the Mediterranean Basin. When in shrub form, it is known as ''Olea europaea'' 'Montra', dwarf olive, or little olive. The species is cultivated in all the countries of the Mediterranean, as well as in Australia, New Zealand, North and South America and South Africa. ''Olea europaea'' is the type species for the genus ''Olea''. The olive's fruit, also called an "olive", is of major agricultural importance in the Mediterranean region as the source of olive oil; it is one of the core ingredients in Mediterranean cuisine. The tree and its fruit give their name to the plant family, which also includes species such as lilac, jasmine, forsythia, and the true ash tree. Thousands of cultivars of the olive tree are known. Olive cultivars may be used primarily for oil, eating, or both. Olives cultivated for consumption ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tephrosia
''Tephrosia'' is a genus of flowering plants in the pea family, Fabaceae. It is widespread in both the Eastern and Western Hemisphere, where it is found in tropical and warm-temperate regions. The generic name is derived from the Greek word τεφρος (''tephros''), meaning "ash-colored," referring to the greyish tint given to the leaves by their dense trichomes. Hoarypea is a common name for plants in this genus, along with Goat's Rue and Devil's Shoestring. Uses Many species in the genus are poisonous, particularly to fish, for their high concentration of rotenone. The black seeds of ''Tephrosia'' species have historically been used by indigenous cultures as fish toxins.NTFlora Northern Territory Flora online:''Flora of the Darwin Region: Fabaceae.''Retrieved 10 June 2018 In the last century, several ''Tephrosia'' species have been studied in connection with the use of rotenone as an insecticide and pesticide.
