Grey Duiker
The common duiker (''Sylvicapra grimmia''), also known as the grey or bush duiker, is a small antelope and the only member of the genus ''Sylvicapra''. This species is found everywhere in Africa south of the Sahara, excluding the Horn of Africa and the rainforests of the central and western parts of the continent. Generally, they are found in habitats with sufficient vegetation cover to allow them to hide—savanna and hilly areas, including the fringes of human settlements. Description Colouration of this species varies widely over its vast geographic range. There are 14 subspecies described, ranging from chestnut in forested areas of Angola to grizzled gray in northern savannas and light brown shades in arid regions. It grows to about in height and generally weighs ; although females are generally larger and heavier than the males. Only the male has horns and these can grow to long. Behavior Breeding is year round and the female gives birth to one fawn after a gestation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pendjari National Park
The Pendjari National Park (french: Parc National de la Pendjari) lies in north western Benin, adjoining the Arli National Park in Burkina Faso. Named for the Pendjari River, the national park is known for its wildlife and is home to some of the last populations of big game like the African forest elephant, lion, hippopotamus, African buffalo, and various antelopes in West Africa. The park is also famous for its richness in birds. The Pendjari National Park has an area of and is part of the WAP complex (W National Park, W-Arli National Park, Arli-Pendjari), a large protected area in Benin, Burkina Faso and Niger. Hills and cliffs in the Togo Mountains, Atakora range are visible from the park. In March 2009, the park was tentatively nominated for UNESCO's World Heritage Site program, and in July 2017, it was officially inscribed as a UNESCO World Heritage Site as part of a transnational extension of the WAP Complex. Ecology The rocky cliffs of the area are sparsely wooded with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of Sub-Saharan Africa
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saur ...

Duikers
A duiker is a small to medium-sized brown antelope native to sub-Saharan Africa, found in heavily wooded areas. The 22 extant species, including three sometimes considered to be subspecies of the other species, form the subfamily Cephalophinae or the tribe Cephalophini. Taxonomy and phylogeny The tribe Cephalophini (formerly the subfamily Cephalophinae) comprises three genera and 22 species, three of which are sometimes considered to be subspecies of the other species. The three genera include ''Cephalophus'' (15 species and three disputed taxa), ''Philantomba'' (three species), and ''Sylvicapra'' (one species). The subfamily was first described by British zoologist John Edward Gray in 1871 in ''Proceedings of the Zoological Society of London''. The scientific name "Cephalophinae" probably comes from the combination of the New Latin word ''cephal'', meaning head, and the Greek word ''lophos'', meaning crest. The three disputed species in ''Cephalophus'' are Brooke's duiker (' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kidepo Valley National Park
Kidepo Valley National Park is a national park in the Karamoja region in northeast Uganda. Kidepo is rugged savannah, dominated by the Mount Morungole and transected by the Kidepo and Narus rivers. Location Kidepo Valley National Park is located near Karenga in Kaabong District, in the northeastern corner of Uganda. The park is approximately , by road northwest of Moroto, the largest town in the sub-region. It is approximately , by road, northeast of Kampala, Uganda's capital and largest city. The northwestern boundary of the park runs along the international frontier with Bira, South Sudan and abuts against its Kidepo Game Reserve. History The Ketebo or Mening are the original inhabitants of the area, who had been living here since 1800. It was gazetted as a game reserve by the British colonial government in 1958, and the people were evicted. The purpose was both to protect the animals from hunting and to prevent further clearing of bush for tsetse fly-control. The evict ...

Generalist And Specialist Species
A generalist species is able to thrive in a wide variety of environmental conditions and can make use of a variety of different resources (for example, a heterotroph with a varied diet). A specialist species can thrive only in a narrow range of environmental conditions or has a limited diet. Most organisms do not all fit neatly into either group, however. Some species are highly specialized (the most extreme case being monophagous, eating one specific type of food), others less so, and some can tolerate many different environments. In other words, there is a continuum from highly specialized to broadly generalist species. Description Omnivores are usually generalists. Herbivores are often specialists, but those that eat a variety of plants may be considered generalists. A well-known example of a specialist animal is the monophagous koala, which subsists almost entirely on eucalyptus leaves. The raccoon is a generalist, because it has a natural range that includes most of North ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Territory (animal)
In ethology, territory is the sociographical area that an animal consistently defends against conspecific competition (or, occasionally, against animals of other species) using agonistic behaviors or (less commonly) real physical aggression. Animals that actively defend territories in this way are referred to as being territorial or displaying territorialism. Territoriality is only shown by a minority of species. More commonly, an individual or a group of animals occupies an area that it habitually uses but does not necessarily defend; this is called its home range. The home ranges of different groups of animals often overlap, and in these overlap areas the groups tend to avoid each other rather than seeking to confront and expel each other. Within the home range there may be a ''core area'' that no other individual group uses, but, again, this is as a result of avoidance. Function The ultimate function of animals inhabiting and defending a territory is to increase the indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carrion
Carrion () is the decaying flesh of dead animals, including human flesh. Overview Carrion is an important food source for large carnivores and omnivores in most ecosystems. Examples of carrion-eaters (or scavengers) include crows, vultures, condors, hawks, eagles, hyenas, Virginia opossum, Tasmanian devils, coyotes and Komodo dragons. Many invertebrates, such as the carrion and burying beetles, as well as maggots of calliphorid flies (such as one of the most important species in '' Calliphora vomitoria'') and flesh-flies, also eat carrion, playing an important role in recycling nitrogen and carbon in animal remains. Carrion begins to decay at the moment of the animal's death, and it will increasingly attract insects and breed bacteria. Not long after the animal has died, its body will begin to exude a foul odor caused by the presence of bacteria and the emission of cadaverine and putrescine. Some plants and fungi smell like decomposing carrion and attract insects that a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gestation Period
In mammals, pregnancy is the period of reproduction during which a female carries one or more live offspring from implantation in the uterus through gestation. It begins when a fertilized zygote implants in the female's uterus, and ends once it leaves the uterus. Fertilization and implantation During copulation, the male inseminates the female. The spermatozoon fertilizes an ovum or various ova in the uterus or fallopian tubes, and this results in one or multiple zygotes. Sometimes, a zygote can be created by humans outside of the animal's body in the artificial process of in-vitro fertilization. After fertilization, the newly formed zygote then begins to divide through mitosis, forming an embryo, which implants in the female's endometrium. At this time, the embryo usually consists of 50 cells. Development After implantation A blastocele is a small cavity on the center of the embryo, and the developing embryonary cells will grow around it. Then, a flat layer cell forms on ...

Kruger National Park
Kruger National Park is a South African National Park and one of the largest game reserves in Africa. It covers an area of in the provinces of Limpopo and Mpumalanga in northeastern South Africa, and extends from north to south and from east to west. The administrative headquarters are in Skukuza. Areas of the park were first protected by the government of the South African Republic in 1898, and it became South Africa's first national park in 1926. To the west and south of the Kruger National Park are the two South African provinces of Limpopo and Mpumalanga, respectively. To the north is Zimbabwe, and to the east is Mozambique. It is now part of the Great Limpopo Transfrontier Park, a peace park that links Kruger National Park with the Gonarezhou National Park in Zimbabwe, and with the Limpopo National Park in Mozambique.
