Yaeda Valley
The Yaeda Valley, or Yaida Valley, is a swampy valley located in Mbulu District of Manyara Region, Tanzania. The Valley is situated south of Lake Eyasi. The valley forms an endorheic basin with no drainage outlet. A low ridge running northeast–southwest separates the valley from the basin of Lake Eyasi. The Yaeda Swamp is fed from the northeast by the Yaeda River, which originates in the Mbulu Highlands to the east.Hughes, R. H. (1992). ''A Directory of African Wetlands''. IUCN, 1992. pp. 253-254. On the valley floor are 16,200 ha of seasonal swamp with extensive areas of rush and sedge, and 8,000 ha of floodplain grassland with ''Vachellia drepanolobium'' thicket at the northern end of the valley that are inundated during periods of exceptionally high rainfall. Above the floodplain are approximately 12,100 ha of wooded hillsides, with ''Vachellia tortilis'' near the edge of the floodplain, '' Vachellia kirkii'' woodland near the ''V. drepanolobium'' thickets at the north end ...

Other native tribes are the Wah ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-necked Grebe
The black-necked grebe or eared grebe (''Podiceps nigricollis'') is a member of the grebe family of water birds. It was described in 1831 by Christian Ludwig Brehm. There are currently three accepted subspecies, including the nominate subspecies. Its breeding plumage features a distinctive ochre-coloured plumage which extends behind its eye and over its ear coverts. The rest of the upper parts, including the head, neck, and breast, are coloured black to blackish brown. The flanks are tawny rufous to maroon-chestnut, and the abdomen is white. When in its non-breeding plumage, this bird has greyish-black upper parts, including the top of the head and a vertical stripe on the back of the neck. The flanks are also greyish-black. The rest of the body is a white or whitish colour. The juvenile has more brown in its darker areas. The subspecies ''californicus'' can be distinguished from the nominate by the former's usually longer bill. The other subspecies, ''P. n. gurneyi'', can be dif ...

Southern Eastern Rift
The Southern Eastern Rift is a freshwater ecoregion in Kenya and Tanzania. It occupies the southern end of the Eastern Rift Valley, or Gregory Rift, and includes a number of closed or endorheic basins which drain into central lakes with no outlet to the sea. The Southern Eastern Rift extends 700 km, from central Kenya to Central Tanzania. The Eastern Rift Valley is 50 to 100 km wide for most of its length, but widens out at its southern end. The lake basins are, from north to south, Lake Baringo, Lake Bogoria, Lake Nakuru, Lake Naivasha, Lake Elementaita, and Lake Magadi in Kenya, and Lake Natron, Lake Manyara, Lake Burungi, Lake Eyasi, Lake Kitangiri, Lake Balangida, Lake Singida, and Lake Sulunga in Tanzania."Southern Eastern Rift" "Freshwater Ecoregions of the World".

Endorheic Basins Of Africa
An endorheic basin (; also spelled endoreic basin or endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but drainage converges instead into lakes or swamps, permanent or seasonal, that equilibrate through evaporation. They are also called closed or terminal basins, internal drainage systems, or simply basins. Endorheic regions contrast with exorheic regions. Endorheic water bodies include some of the largest lakes in the world, such as the Caspian Sea, the world's largest inland body of water. Basins with subsurface outflows which eventually lead to the ocean are generally not considered endorheic; they are cryptorheic. Endorheic basins constitute local base levels, defining a limit of erosion and deposition processes of nearby areas. Etymology The term was borrowed from French ''endor(rh)éisme'', coined from the combining form ''endo-'' (from grc, ἔνδον ''éndon'' 'withi ...

Pastoralism
Pastoralism is a form of animal husbandry where domesticated animals (known as "livestock") are released onto large vegetated outdoor lands (pastures) for grazing, historically by nomadic people who moved around with their herds. The animal species involved include cattle, camels, goats, yaks, llamas, reindeer, horses and sheep. Pastoralism occurs in many variations throughout the world, generally where environmental characteristics such as aridity, poor soils, cold or hot temperatures, and lack of water make crop-growing difficult or impossible. Operating in more extreme environments with more marginal lands means that pastoral communities are very vulnerable to the effects of global warming. Pastoralism remains a way of life in many geographic areas, including Africa, the Tibetan plateau, the Eurasian steppes, the Andes, Patagonia, the Pampas, Australia and many other places. , between 200 million and 500 million people globally practised pastoralism, and 75% ...

Hadza People
The Hadza, or Hadzabe (''Wahadzabe'' in Swahili), are a Tanzanian indigenous ethnic group mostly based in southwest Karatu District of Arusha Region. They live around Lake Eyasi in the central Rift Valley and in the neighboring Serengeti Plateau. There are, as of 2015, between 1,200 and 1,300 Hadza people living in Tanzania, however only around 400 Hadza still survive exclusively based on the traditional means of foraging. Additionally, the increasing impact of tourism and encroaching pastoralists pose serious threats to the continuation of their traditional way of life. Genetically, the Hadza are not closely related to any other people. Once classified among the Khoisan languages, primarily because it has clicks, the Hadza language (Hadzane) is actually thought to be an isolate, unrelated to any other. Hadzane is an entirely oral language, but it is not predicted to be in danger of extinction. UNESCO states that the language is not endangered but vulnerable because most child ...

Leopard
The leopard (''Panthera pardus'') is one of the five extant species in the genus '' Panthera'', a member of the cat family, Felidae. It occurs in a wide range in sub-Saharan Africa, in some parts of Western and Central Asia, Southern Russia, and on the Indian subcontinent to Southeast and East Asia. It is listed as Vulnerable on the IUCN Red List because leopard populations are threatened by habitat loss and fragmentation, and are declining in large parts of the global range. The leopard is considered locally extinct in Hong Kong, Singapore, South Korea, Jordan, Morocco, Togo, the United Arab Emirates, Uzbekistan, Lebanon, Mauritania, Kuwait, Syria, Libya, Tunisia and most likely in North Korea, Gambia, Laos, Lesotho, Tajikistan, Vietnam and Israel. Contemporary records suggest that the leopard occurs in only 25% of its historical global range. Compared to other wild cats, the leopard has relatively short legs and a long body with a large skull. Its fur is marked with rosett ... [...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] |
Knob-billed Duck
The knob-billed duck (''Sarkidiornis melanotos''), or African comb duck, is a duck found in tropical wetlands in Sub-Saharan Africa, Madagascar and the Indian Subcontinent from northern India to Laos and extreme southern China. Most taxonomic authorities split this species and the comb duck from each other. The supposed extinct "Mauritian comb duck" is based on misidentified remains of the Mauritius sheldgoose (''Alopochen mauritiana''); this was realized as early as 1897, but the mistaken identity can still occasionally be found in recent sources. Description and systematics This common species is unmistakable. It is one of the largest species of duck. Length can range from , wingspan ranges from and weight from . biodiver ...

Fulvous Whistling Duck
The fulvous whistling duck or fulvous tree duck (''Dendrocygna bicolor'') is a species of whistling duck that breeds across the world's tropical regions in much of Mexico and South America, the West Indies, the southern United States, sub-Saharan Africa and the Indian subcontinent. It has plumage that is mainly reddish brown, long legs and a long grey bill, and shows a distinctive white band across its black tail in flight. Like other members of its ancient lineage, it has a whistling call which is given in flight or on the ground. Its preferred habitat consists of wetlands with plentiful vegetation, including shallow lakes and paddy fields. The nest, built from plant material and unlined, is placed among dense vegetation or in a tree hole. The typical clutch is around ten whitish eggs. The breeding adults, which pair for life, take turns to incubate, and the eggs hatch in 24–29 days. The downy grey ducklings leave the nest within a day or so of hatching, but the parents contin ...

Ruff (bird)
The ruff (''Calidris pugnax'') is a medium-sized wading bird that breeds in marshes and wet meadows across northern Eurasia. This highly gregarious sandpiper is migratory and sometimes forms huge flocks in its winter grounds, which include southern and western Europe, Africa, southern Asia and Australia. The ruff is a long-necked, pot-bellied bird. This species shows marked sexual dimorphism; the male is much larger than the female (the reeve), and has a breeding plumage that includes brightly coloured head tufts, bare orange facial skin, extensive black on the breast, and the large collar of ornamental feathers that inspired this bird's English name. The female and the non-breeding male have grey-brown upperparts and mainly white underparts. Three differently plumaged types of male, including a rare form that mimics the female, use a variety of strategies to obtain mating opportunities at a lek, and the colourful head and neck feathers are erected as part of the elaborate mai ...
