Wildlife Of Sudan
The wildlife of Sudan is composed of its flora and fauna. A variety of climate types in Sudan results in a wide range of habitats and the range of wildlife is diverse. Some 287 species of mammal have been recorded in the country and some 634 species of bird. Geography Sudan is located in northeastern Africa, with an 853 km (530 mi) coastline bordering on the Red Sea. The terrain is generally flat, with low-lying plains broken by a few mountain ranges. In the west, the Marrah Mountains are the highest part of Sudan, while in the east lie the Red Sea Hills. The Blue Nile and the White Nile converge at Khartoum to form the Nile, which flows northwards to the Mediterranean Sea. The climate ranges from hyper-arid in the north of the country to tropical wet-and-dry in the south. Variations in the length of the wet and dry seasons depend on which of two air flows predominates: dry northern winds from the Sahara and the Arabian Peninsula or moist southwesterly winds from the Co ...

Agricultural Activities
Agriculture or farming is the practice of cultivating Plant, plants and livestock. Agriculture was the key development in the rise of Sedentism, sedentary human civilization, whereby farming of Domestication, domesticated species created food Economic surplus, surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into Food, foods, Fiber, fibers, fuels, and raw materials (such as Natural rubber, rubber). Food clas ...

Adansonia
''Adansonia'' is a genus made up of eight species of medium-to-large deciduous trees known as baobabs ( or ). They are placed in the Malvaceae family, subfamily Bombacoideae. They are native to Madagascar, mainland Africa, and Australia.Tropicos.org. Missouri Botanical Garden. 8 Jul 2020 http://www.tropicos.org The trees have also been introduced to other regions such as Asia. The generic name honours Michel Adanson, the French naturalist and explorer who described ''Adansonia digitata''. The baobab is also known as the "upside down tree", a name that originates from several myths. They are among the most long-lived of vascular plantsAdrian Patrut et al.

Rock Hyrax
The rock hyrax (; ''Procavia capensis''), also called dassie, Cape hyrax, rock rabbit, and (in the King James Bible) coney, is a medium-sized terrestrial mammal native to Africa and the Middle East. Commonly referred to in South Africa as the dassie (; af, klipdassie), it is one of the five living species of the order Hyracoidea, and the only one in the genus ''Procavia''. Rock hyraxes weigh and have short ears and tails. Rock hyraxes are found at elevations up to above sea level in habitats with rock crevices, allowing them to escape from predators. They are the only extant terrestrial afrotherians in the Middle East. Hyraxes typically live in groups of 10–80 animals, and forage as a group. They have been reported to use sentries to warn of the approach of predators. Having incomplete thermoregulation, they are most active in the morning and evening, although their activity pattern varies substantially with season and climate. Over most of its range, the rock hyrax is not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crested Porcupine
The crested porcupine (''Hystrix cristata''), also known as the African crested porcupine, is a species of rodent in the family Hystricidae native to Italy, North Africa and sub-Saharan Africa. Characteristics The adult crested porcupine has an average head and body length around long, discounting the tail, and weighs from . It is one of the largest rodents in the world. Almost the entire body is covered with bristles which are either dark brown or black and rather coarse. This mammal is recognizable by the quills that run along the head, nape, and back that can be raised into a crest, hence the name crested porcupine. Also, some sturdier quills which are about in length run along the sides and back half of the body. These sturdier quills are used, for the most part, for defense and are usually marked with light and dark bands which alternate; these are not firmly attached. This porcupine has a short tail which has rattle quills at the end. The rattle quills broaden at t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elephant Shrew
Elephant shrews, also called jumping shrews or sengis, are small insectivorous mammals native to Africa, belonging to the family Macroscelididae, in the order Macroscelidea. Their traditional common English name "elephant shrew" comes from a perceived resemblance between their long noses and the trunk of an elephant, and their superficial similarity with shrews (family Soricidae) in the order Eulipotyphla. However, phylogenetic analysis has revealed that elephant shrews are not properly classified with true shrews, but are in fact more closely related to elephants than to shrews. In 1997, the biologist Jonathan Kingdon proposed that they instead be called "sengis" (singular ''sengi''), a term derived from the Bantu languages of Africa, and in 1998, they were classified into the new clade Afrotheria. They are widely distributed across the southern part of Africa, and although common nowhere, can be found in almost any type of habitat, from the Namib Desert to boulder-strewn ou ...

Insectivore
A robber fly eating a hoverfly An insectivore is a carnivorous animal or plant that eats insects. An alternative term is entomophage, which can also refer to the human practice of eating insects. The first vertebrate insectivores were amphibians. When they evolved 400 million years ago, the first amphibians were piscivores, with numerous sharp conical teeth, much like a modern crocodile. The same tooth arrangement is however also suited for eating animals with exoskeletons, thus the ability to eat insects is an extension of piscivory. At one time, insectivorous mammals were scientifically classified in an order called Insectivora. This order is now abandoned, as not all insectivorous mammals are closely related. Most of the Insectivora taxa have been reclassified; those that have not yet been reclassified and found to be truly related to each other remain in the order Eulipotyphla. Although individually small, insects exist in enormous numbers. Insects make u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose i ...

Papyrus
Papyrus ( ) is a material similar to thick paper that was used in ancient times as a writing surface. It was made from the pith of the papyrus plant, '' Cyperus papyrus'', a wetland sedge. ''Papyrus'' (plural: ''papyri'') can also refer to a document written on sheets of such material, joined side by side and rolled up into a scroll, an early form of a book. Papyrus is first known to have been used in Egypt (at least as far back as the First Dynasty), as the papyrus plant was once abundant across the Nile Delta. It was also used throughout the Mediterranean region. Apart from a writing material, ancient Egyptians employed papyrus in the construction of other artifacts, such as reed boats, mats, rope, sandals, and baskets. History Papyrus was first manufactured in Egypt as far back as the fourth millennium BCE.H. Idris Bell and T.C. Skeat, 1935"Papyrus and its uses"(British Museum pamphlet). The earliest archaeological evidence of papyrus was excavated in 2012 and 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sudd
The Sudd (' or ', Dinka language, Dinka: Toc) is a vast swamp in South Sudan, formed by the White Nile's ''Mountain Nile, Baḥr al-Jabal'' section. The Arabic language, Arabic word ' is derived from ' (), meaning "barrier" or "obstruction". The term "the sudd" has come to refer to any large solid floating vegetation island or mat. The area which the swamp covers is one of the world's largest wetlands and the largest freshwater wetland in the Nile Basin. For many years the swamp, and especially its thicket of vegetation, proved an impenetrable barrier to navigation along the Nile. The ancient Egyptians failed to penetrate the Sudd and reach the areas south of it. In AD 61, Nero's exploration of the Nile, a party of Roman soldiers sent by the Emperor Nero proceeded up the White Nile but were not able to get beyond the Sudd, which marked the limit of Roman penetration into equatorial Africa. For the same reasons in later times, the Nile#Search for the source of the Nile, search for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vachellia Tortilis
''Vachellia tortilis'', widely known as ''Acacia tortilis'' but now attributed to the genus ''Vachellia'', is the umbrella thorn acacia, also known as ''umbrella thorn'' and Israeli babool, a medium to large canopied tree native to most of Africa, primarily to the savanna and Sahel of Africa (especially the Somali peninsula and Sudan), but also occurring in the Middle East. Distribution and growing conditions ''Vachellia tortilis'' is widespread in Africa, being found in countries like Tunisa, Morocco, Uganda, Angola, Zimbabwe, Djibouti, and Botswana. It tends to grow in areas where temperatures vary from and rainfall is anywhere from about per year. Characteristics In extremely arid conditions, it may occur as a small, wiry bush. It grows up to in height. The tree carries leaves that grow to approx. in length with between 4 and 10 pair of pinnae each with up to 15 pairs of leaflets. Flowers are small and white, highly aromatic, and occur in tight clusters. Seeds a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sorghum
''Sorghum'' () is a genus of about 25 species of flowering plants in the grass family (Poaceae). Some of these species are grown as cereals for human consumption and some in pastures for animals. One species is grown for grain, while many others are used as fodder plants, either cultivated in warm climates worldwide or naturalized in pasture lands. Taxonomy ''Sorghum'' is in the Poaceae (grass) subfamily Panicoideae and the tribe Andropogoneae (the same as maize, big bluestem and sugarcane). Species Accepted species recorded include: Distribution and habitat Seventeen of the 25 species are native to Australia, with the range of some extending to Africa, Asia, Mesoamerica, and certain islands in the Indian and Pacific Oceans. Toxicity In the early stages of the plants' growth, some species of sorghum can contain levels of hydrogen cyanide, hordenine, and nitrates, which are lethal to grazing animals. Plants stressed by drought or heat can also contain toxic lev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
