Gcwihaba
Gcwihaba is a cave in Botswana located in Okavango Delta region. The Gcwihaba Caves were part of the Kalahari landscape around 2 million years ago, at least for the entire period of the Pleistocene. The name of the cave is a San word and stands for "hyena's lair". The cave is situated 10 km away from the Namibian border. In 1932 it was first shown to a European, Ghanzi region farmer Martinus Drotsky, and the main cavern was named Drotsky's cavern after him. Gwchihaba is a Botswana National Monument under the Monuments, Relics and Antiquities Act, and has been put forward to become a UNESCO World Heritage Site in 1999. It is the type locality of the mineral gwihabaite (IMA1994-011). Even though nothing was found in the first 50 cm of cave during the excavations to affirm that the cave was settled as a camp, 51 stone artefacts (33 of them made from travertine) were released in the upper 50 cm of the cave. 50–80 cm of the cave is called The Terminal Pl ...

Gwihabaite
Gwihabaite is a rare ammonium potassium nitrate mineral (NH4,K)(NO3). It is orthorhombic in form, colorless with a vitreous luster. It has a Mohs hardness of 5 and a specific gravity of 1.77. It is deliquescent and water-soluble. The mineral is also known as ''nitrammite''. It was first described in 1996 for an occurrence in Gcwihaba Caves (Drotsky's Cavern, type locality), Maun, North-West District, Botswana. The spelling of the name was simplified, omitting the "c", which represents the "click" sound used by the San people. It occurs as incrustations and efflorescences on cave surfaces formed by bacterial action on bat guano Guano (Spanish from qu, wanu) is the accumulated excrement of seabirds or bats. As a manure, guano is a highly effective fertilizer due to the high content of nitrogen, phosphate, and potassium, all key nutrients essential for plant growth. ....

Botswana
Botswana (, ), officially the Republic of Botswana ( tn, Lefatshe la Botswana, label= Setswana, ), is a landlocked country in Southern Africa. Botswana is topographically flat, with approximately 70 percent of its territory being the Kalahari Desert. It is bordered by South Africa to the south and southeast, Namibia to the west and north, and Zimbabwe to the northeast. It is connected to Zambia across the short Zambezi River border by the Kazungula Bridge. A country of slightly over 2.3 million people, Botswana is one of the most sparsely populated countries in the world. About 11.6 percent of the population lives in the capital and largest city, Gaborone. Formerly one of the world's poorest countries—with a GDP per capita of about US$70 per year in the late 1960s—it has since transformed itself into an upper-middle-income country, with one of the world's fastest-growing economies. Modern-day humans first inhabited the country over 200,000 years ago. The Tswa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Slit-faced Bat
''Nycteris'' comprises a genus of bats commonly called slit-faced or hollow-faced bats. They are grouped in the family Nycteridae. The bats are found in East Malaysia, Indonesia, and many parts of Africa. Description They are small bats, from in body length, and with grey, brown, or reddish fur. The skull is distinguished by a characteristic interorbital concavity, externally connected to a long slit that runs down the centre of their faces from between the eyes to the nostrils, and probably assists in echolocation. They have large ears, and a complex nose-leaf. Their tails end in a T-shape, formed from cartilage, a unique feature among mammals. Their dental formula is: Nycterids have a reduction of the hand phalanges: the 2nd digit has only metacarpus, and the 3rd only two phalanges. The pectoral girdle has parallel features to birds. The sternum is strongly developed and the mesosternum has a keel. Habitat and biology Slit-faced bats inhabit rainforests and savanna, and r ...

Commerson's Roundleaf Bat
Commerson's roundleaf bat (''Macronycteris commersoni''), also known as Commerson's leaf-nosed bat, is a species of bat endemic to Madagascar. It is named after French naturalist Philibert Commerson (1727-1773). Bat populations of Africa or São Tomé and Príncipe formerly considered part of this species are now classified separately as '' M. gigas'', '' M. thomensis'' or '' M. vattatus'', while one from Madagascar was split off to become '' M. cryptovalorona''. It was formerly placed in the genus ''Hipposideros'', but moved to the resurrected ''Macronycteris'' in 2017 on the basis of molecular evidence. Distribution and habitat The species is found in forests of several types on Madagascar, including dry deciduous forest, littoral forest and gallery forest, at elevations from sea level to at least 1350 m. It roosts in caves, on mature trees and in buildings. While its habitat is largely intact forest, it sometimes feeds near or in villages. Biology Commerson's roundleaf bat ...

Rüppell's Parrot
Rüppell's parrot (''Poicephalus rueppellii'') or Rueppell's parrot, is a bird that is endemic to southwestern Africa from central Namibia to southwest Angola. It lives in savanna where there are trees or in dry woodland. It is more common near streams or rivers. The name commemorates the German naturalist and explorer Eduard Rüppell. Description Rüppell's parrot is 22–25 cm (9 in) long and weighs 121–156 g. It has an overall dark brown color and its head is dark greyish. Both adult male and female birds have some yellow feathers on the leading edge of the wings, and yellow feathers covering their upper legs; in immature birds, the yellow is dull or missing. They are sexually dimorphic; adult female birds have blue feathers on the lower back and the rump, whilst male birds lose this blue feather coloration as they become mature. Diet The Ruppell's Parrot eats mainly seeds, flowers, leaves, anthropods, and bark. It has been found that during the rainy seasons th ...

Travertine
Travertine ( ) is a form of terrestrial limestone deposited around mineral springs, especially hot springs. It often has a fibrous or concentric appearance and exists in white, tan, cream-colored, and even rusty varieties. It is formed by a process of rapid precipitation of calcium carbonate, often at the mouth of a hot spring or in a limestone cave. In the latter, it can form stalactites, stalagmites, and other speleothems. It is frequently used in Italy and elsewhere as a building material. Similar (but softer and extremely porous) deposits formed from ambient-temperature water are known as tufa. Definition Travertine is a sedimentary rock formed by the chemical precipitation of calcium carbonate minerals from fresh water, typically in springs, rivers, and lakes; that is, from surface and ground waters. In the broadest sense, travertine includes deposits in both hot and cold springs, including the porous, spongy rock known as tufa, and also the cave features known as speleot ...

African Bullfrog
The African bullfrog (''Pyxicephalus adspersus'') is a species of frog in the family Pyxicephalidae. It is also known as the pixie frog due to its scientific name. It is found in Angola, Botswana, Kenya, Malawi, Mozambique, Namibia, South Africa, Tanzania, Uganda, Zambia, Zimbabwe, and possibly the Democratic Republic of the Congo. It has been extirpated from Eswatini. It has long been confused with the edible bullfrog (''P. edulis'') and species boundaries between them, including exact range limits, are not fully understood. Additionally, '' P. angusticeps'' of coastal East Africa only was revalidated as a separate species in 2013. The natural habitat of the African bullfrog is moist to dry savanna, subtropical to tropical dry shrubland, intermittent freshwater lakes, intermittent freshwater marshes, arable land, pastureland, canals, and flooded ditches. It is among the largest anurans on the planet, sixth only to the goliath frog, the helmeted water toad, the Lake Junin frog ...
