Namib Desert
The Namib ( ; pt, Namibe) is a coastal desert in Southern Africa. The name is of Khoekhoegowab origin and means "vast place". According to the broadest definition, the Namib stretches for more than along the Atlantic coasts of Angola, Namibia, and South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River (Western Cape), Olifants River in Western Cape, South Africa. The Namib's northernmost portion, which extends from the Angola-Namibia border, is known as Moçâmedes Desert, while its southern portion approaches the neighboring Kalahari Desert. From the Atlantic coast eastward, the Namib gradually ascends in elevation, reaching up to inland to the foot of the Great Escarpment, Southern Africa, Great Escarpment. Annual precipitation ranges from in the most arid regions to at the escarpment, making the Namib the only true desert in southern Africa. Having endured Desert climate, arid or Semi-arid climate, semi-arid cond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moderate Resolution Imaging Spectroradiometer
The Moderate Resolution Imaging Spectroradiometer (MODIS) is a satellite-based sensor used for earth and climate measurements. There are two MODIS sensors in Earth orbit: one on board the Terra (satellite), Terra (Earth Observing System, EOS AM) satellite, launched by NASA in 1999; and one on board the Aqua (satellite), Aqua (EOS PM) satellite, launched in 2002. MODIS has now been replaced by the VIIRS, which first launched in 2011 aboard the Suomi NPP satellite. The MODIS instruments were built by Santa Barbara Remote Sensing. They capture data in 36 spectral bands ranging in wavelength from 0.4 μm to 14.4 μm and at varying spatial resolutions (2 bands at 250 m, 5 bands at 500 m and 29 bands at 1 km). Together the instruments image the entire Earth every 1 to 2 days. They are designed to provide measurements in large-scale global dynamics including changes in Earth's cloud cover, radiation budget and processes occurring in the oceans, on land, and in the Atmos ...

Badain Jaran Desert
The Badain Jaran Desert () is a desert in China which spans the provinces of Gansu, Ningxia and Inner Mongolia. It covers an area of . By size it is the third largest desert in China. This desert is home to some of the tallest stationary dunes on Earth, with some reaching a height of more than , although most average at around . Its tallest dune is also measured, from base to peak, as the world's third tallest dune and highest stationary dune in the world. The desert also features over 100 spring-fed lakes that lie between the dunes, some of which are fresh water while others are extremely saline. These lakes give the desert its name which is Mongolian for "mysterious lakes". These lakes are not completely studied and high pH lakes harbor extremely interesting animal communities. It is also crossed by one river, the Ruo Shui ("weak water"), which has formed an alluvial plain in the desert. Geography Measuring over , the Badain Jaran Desert covers a significant part of the south ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Zebra
The mountain zebra (''Equus zebra'') is a zebra species in the family Equidae, native to southwestern Africa. There are two subspecies, the Cape mountain zebra (''E. z. zebra'') found in South Africa and Hartmann's mountain zebra (''E. z. hartmannae'') found in south-western Angola and Namibia. Taxonomy The mountain zebra comprises two subspecies: In 2004, C. P. Groves and C. H. Bell investigated the taxonomy of the zebras (genus ''Equus'', subgenus ''Hippotigris''). They concluded that the mountain zebra (''Equus zebra zebra'') and Hartmann's mountain zebra (''Equus zebra hartmannae'') are distinct, and suggested that the two would be better classified as separate species, ''Equus zebra'' and ''Equus hartmannae''. However, in a sexual genetic study that included 295 mountain zebra specimens, Moodley and Harley (2005) found nothing to support the separation of the two mountain zebra populations into separate species. They concluded that the Cape mountain zebra and Hartmann' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
African Bush Elephant
The African bush elephant (''Loxodonta africana'') is one of two extant African elephant species and one of three extant elephant species. It is the largest living terrestrial animal, with bulls reaching a shoulder height of up to and a body mass of up to . It is distributed across 37 African countries and inhabits forests, grasslands and woodlands, wetlands and agricultural land. Since 2021, it has been listed as Endangered on the IUCN Red List. It is threatened foremost by habitat destruction, and in parts of its range also by poaching for meat and ivory. It is a social mammal, travelling in herds composed of cows and their offspring. Adult bulls usually live alone or in small bachelor groups. It is a herbivore, feeding on grasses, creepers, herbs, leaves, and bark. The menstrual cycle lasts three to four months, and females are pregnant for 22 months, the longest gestation period of any mammal. Taxonomy ''Elephas africanus'' was the scientific name proposed by Johann Fri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Namib-Naukluft National Park
The Namib-Naukluft Park is a national park in western Namibia, situated between the coast of the Atlantic Ocean and the edge of the Great Escarpment. It encompasses part of the Namib Desert (considered the world's oldest desert), the Naukluft mountain range, and the lagoon at Sandwich Harbour. The best-known area of the park and one of the main visitor attractions in Namibia is Sossusvlei, a clay pan surrounded by dunes, and Sesriem, a small canyon of the Tsauchab. The desert research station of Gobabeb is situated within the park. Location and description With an overall area of , the Namib-Naukluft National Park was at the time of its last expansion the largest game park in Africa and the fourth largest in the world. It consists of a strip of land on the Atlantic Ocean, including of sea, that extends roughly north-to-south from the Swakop River to the B4 road to Lüderitz.

Lion
The lion (''Panthera leo'') is a large Felidae, cat of the genus ''Panthera'' native to Africa and India. It has a muscular, broad-chested body; short, rounded head; round ears; and a hairy tuft at the end of its tail. It is sexually dimorphic; adult male lions are larger than females and have a prominent mane. It is a social species, forming groups called ''prides''. A lion's pride consists of a few adult males, related females, and cubs. Groups of female lions usually hunt together, preying mostly on large ungulates. The lion is an apex predator, apex and keystone predator; although some lions scavenge when opportunities occur and have been known to hunt Human, humans, lions typically don't actively seek out and prey on humans. The lion inhabits grasslands, savannas and shrublands. It is usually more diurnality, diurnal than other wild cats, but when persecuted, it adapts to being active nocturnality, at night and crepuscular, at twilight. During the Neolithic period, the li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Fur Seal
The brown fur seal (''Arctocephalus pusillus''), also known as the Cape fur seal, South African fur seal and Australian fur seal, is a species of fur seal. Description The brown fur seal is the largest and most robust member of the fur seals. It has a large and broad head with a pointed snout that may be flat or turned up slightly. They have external ear flaps (pinnae) and their whiskers (vibrissae) are long, and may extend backward past the pinnae, especially in adult males. The fore flippers are covered with sparse hair over about three-quarters of their length. The hind flippers are short relative to the large body, with short, fleshy tips on the digits. The size and weight of the brown fur seal depends on the subspecies. The Southern African subspecies is on average slightly larger than the Australian subspecies. Males of the African subspecies (''A. p. pusillus'') are in length on average and weigh . Females are smaller, averaging in length and typically weighing .King, ...

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nama People
Nama (in older sources also called Namaqua) are an African ethnic group of South Africa, Namibia and Botswana. They traditionally speak the Nama language of the Khoe-Kwadi language family, although many Nama also speak Afrikaans. The Nama People (or Nama-Khoe people) are the largest group of the Khoikhoi people, most of whom have disappeared as a group, except for the Namas. Many of the Nama clans live in Central Namibia and the other smaller groups live in Namaqualand, which today straddles the Namibian border with South Africa. History For thousands of years, the Khoisan peoples of South Africa and southern Namibia maintained a nomadic life, the Khoikhoi as pastoralists and the San people as hunter-gatherers. The Nama are a Khoikhoi group. The Nama originally lived around the Orange River in southern Namibia and northern South Africa. The early colonialists referred to them as Hottentots. Their alternative historical name, "Namaqua", stems from the addition of the Khoekhoe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herero People
The Herero ( hz, Ovaherero) are a Bantu ethnic group inhabiting parts of Southern Africa. There were an estimated 250,000 Herero people in Namibia in 2013. They speak Otjiherero, a Bantu language. Though the Herero primarily reside in Namibia, there are also significant populations in Botswana and Angola. In Botswana, the Hereros or Ovaherero are mostly found in Maun and some villages surrounding Maun. These villages among others are Sepopa, Toromuja, Karee and Etsha. Some of them are at Mahalapye. In the South eastern part of Botswana they are at Pilane. There are also a few of them in the Kgalagadi South, that is Tsabong, Omawaneni, Draaihoek and Makopong Villages. Overview Unlike most Bantu, who are primarily subsistence farmers,Immaculate N.

Himba People
The Himba (singular: OmuHimba, plural: OvaHimba) are an indigenous people with an estimated population of about 50,000 people living in northern Namibia, in the Kunene Region (formerly Kaokoland) and on the other side of the Kunene River in southern Angola. There are also a few groups left of the OvaTwa, who are also OvaHimba, but are hunter-gatherers. Culturally distinguishable from the Herero people, the OvaHimba are a semi-nomadic, pastoralist people and speak OtjiHimba, a variety of Herero, which belongs to the Bantu family within Niger–Congo. The OvaHimba are semi-nomadic as they have base homesteads where crops are cultivated, but may have to move within the year depending on rainfall and where there is access to water. The OvaHimba are considered the last (semi-) nomadic people of Namibia. Culture Subsistence economy The OvaHimba are predominantly livestock farmers who breed fat-tailed sheep and goats, but count their wealth in the number of their cattle. They al ...
