South African Springhare
The South African springhare (''Pedetes capensis'') ( af, springhaas) is a medium-sized terrestrial and burrowing rodent. Despite the name, it is not a hare. It is one of two extant species in the genus ''Pedetes'', and is native to southern Africa. Formerly, the genus was considered monotypic and the East African springhare (''P. surdaster'') was included in ''P. capensis''. Springhares live throughout semi-arid areas in southern Africa, preferentially in sandy plains and pans with short grasses. In agricultural areas, springhares can be considered a pest due to their destructive feeding on crops. However, they are not currently considered under an impending risk of extinction. Characteristics The springhare resembles a small kangaroo with well-developed hind legs, short front legs, and a long tail which comprises half of its body length. As well as a long tail, springhares have relatively large eyes and ears. Adults can attain in length and weigh an average of . Similar to ...

Calabrian (stage)
Calabrian is a subdivision of the Pleistocene Epoch of the geologic time scale, defined as 1.8 Ma—774,000 years ago ± 5,000 years, a period of ~. The end of the stage is defined by the last magnetic pole reversal (781 ± 5 Ka) and plunge into an ice age and global drying possibly colder and drier than the late Miocene ( Messinian) through early Pliocene (Zanclean) cold period. Originally the Calabrian was a European faunal stage primarily based on mollusk fossils. It has become the second geologic age in the Early Pleistocene. Many of the mammalian faunal assemblages of the Early Pleistocene start in the Gelasian. For example, the Platygonus and other Blancan fauna appear first in the Gelasian. History of the definition of the Calabrian Because sea shells are much more abundant as fossils, 19th- and early-20th-century geo-scientists used the plentiful and well-differentiatable Mollusca (mollusks) and Brachiopods to identify stratigraphic boundaries. Thus the Calabrian was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-footed Cat
The black-footed cat (''Felis nigripes''), also called the small-spotted cat, is the smallest wild cat in Africa, having a head-and-body length of . Despite its name, only the soles of its feet are black or dark blackish brown. With its bold small spots and stripes on the tawny fur, it is well camouflaged, especially on moonlit nights. It bears black streaks running from the corners of the eyes along the cheeks, and its banded tail has a black tip. The first black-footed cat known to science was discovered in the northern Karoo of South Africa and described in 1824. It is endemic to the arid steppes and grassland savannas of Southern Africa. In the late 1960s, it was recorded in southern Botswana, but only few authentic records exist in Namibia, in southern Angola, and in southern Zimbabwe. Due to its restricted distribution, it has been listed as a vulnerable species on the IUCN Red List since 2002. The population is suspected to be declining due to poaching of prey species f ...

Mammals Of Southern 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 Saurops ...

Biofluorescence
Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore a lower photon energy, than the absorbed radiation. A perceptible example of fluorescence occurs when the absorbed radiation is in the ultraviolet region of the electromagnetic spectrum (invisible to the human eye), while the emitted light is in the visible region; this gives the fluorescent substance a distinct color that can only be seen when the substance has been exposed to UV light. Fluorescent materials cease to glow nearly immediately when the radiation source stops, unlike phosphorescent materials, which continue to emit light for some time after. Fluorescence has many practical applications, including mineralogy, gemology, medicine, chemical sensors (fluorescence spectroscopy), fluorescent labelling, dyes, biological detectors, cosmic-ray detection, vacuum ...

Batswana
The Tswana ( tn, Batswana, singular ''Motswana'') are a Bantu-speaking ethnic group native to Southern Africa. The Tswana language is a principal member of the Sotho-Tswana language group. Ethnic Tswana made up approximately 85% of the population of Botswana in 2011. Batswana are the native people of south and eastern Botswana, and the Gauteng, North West, Northern Cape and Free State provinces of South Africa, where the majority of Batswana are located. History Early history of Batswana The Batswana are descended mainly from Bantu-speaking tribes along with the Khoi-San. Tswana tribe migrated southward to Africa around 600 CE, living in tribal enclaves as farmers and herders. Several Iron Age cultures flourished around the 900 CE, including the Toutswemogala Hill Iron Age settlement. The Toutswe were in the eastern region of what is now Botswana, relying on Tswana cattle breed held in kraals as their source of wealth. The arrival of the ancestors of the Tswana-speaker ...

San People
The San peoples (also Saan), or Bushmen, are members of various Khoe, Tuu, or Kxʼa-speaking indigenous hunter-gatherer cultures that are the first cultures of Southern Africa, and whose territories span Botswana, Namibia, Angola, Zambia, Zimbabwe, Lesotho and South Africa. In 2017, Botswana was home to approximately 63,500 San people (roughly 2.8% of the population) making it the country with the highest number of San people. Definition The term "San" has a long vowel and is spelled Sān (in Khoekhoegowab orthography). It is a Khoekhoe exonym with the meaning of "foragers" and was often used in a derogatory manner to describe nomadic, foraging people. Based on observation of lifestyle, this term has been applied to speakers of three distinct language families living between the Okavango River in Botswana and Etosha National Park in northwestern Namibia, extending up into southern Angola; central peoples of most of Namibia and Botswana, extending into Zambia and Zimbabwe ...

Ground Pangolin
The ground pangolin (''Smutsia temminckii''), also known as Temminck's pangolin, Cape pangolin or steppe pangolin, is one of four species of pangolins which can be found in Africa, and the only one in southern and eastern Africa. The animal was named for the Dutch zoologist Coenraad Jacob Temminck. As a group, pangolins are among the most critically endangered and illegally trafficked animals in the world. Physical description Pangolins are almost completely covered in overlapping, protective scales, which makes up about 20% of their body weight.African Wildlife Foundatio"Pangolin"/ref> The scales are composed of keratin, the same material that forms human hair and fingernails, and give pangolins an appearance similar to a pinecone or artichoke.John D.
