Zanzibar Servaline Genet
The Zanzibar servaline genet (''Genetta servalina archeri'') is a recently discovered subspecies of servaline genet endemic to Unguja Island in the Tanzanian archipelago of Zanzibar. Its conservation status is uncertain. Evolutionary history The closest known relative of the Zanzibar servaline genet is Lowe's servaline genet, ''G. s. lowei'', a subspecies which is found in the Eastern Arc Mountains of mainland Tanzania. These two animals have presumably been evolving independently since at least the end of the last ice age, when Unguja was separated from continental Africa by rising sea levels. The survival of the servaline genet on the island parallels that of the endemic Zanzibar leopard, and the Zanzibar red colobus. Discovery and description Although the servaline was known to rural Zanzibaris, zoologists remained unaware of its existence until the last decade of the 20th century. In 1995 Tony Archer, a wildlife consultant working in Zanzibar, acquired a dried skin and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Van Rompaey
A van is a type of road vehicle used for transporting goods or people. Depending on the type of van, it can be bigger or smaller than a pickup truck and SUV, and bigger than a common car. There is some varying in the scope of the word across the different English-speaking countries. The smallest vans, microvans, are used for transporting either goods or people in tiny quantities. Mini MPVs, compact MPVs, and MPVs are all small vans usually used for transporting people in small quantities. Larger vans with passenger seats are used for institutional purposes, such as transporting students. Larger vans with only front seats are often used for business purposes, to carry goods and equipment. Specially-equipped vans are used by television stations as mobile studios. Postal services and courier companies use large step vans to deliver packages. Word origin and usage Van meaning a type of vehicle arose as a contraction of the word caravan. The earliest records of a van as a vehicle i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Tanzania
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of Tanzania
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 wi ...

Jozani-Chwaka Bay National Park
The Jozani Chwaka Bay National Park is a national park in Tanzania located on the island of Zanzibar. It is the only national park in Zanzibar. The Zanzibar red colobus, '' Procolobus kirkii'' (its population count is about 1000) found in the park, a rain forest species (unlike the black-and-white colobus found in other regions of Africa), is also known as Kirk's red colobus, named after Sir John Kirk, the British Resident of Zanzibar who had first brought it to the attention of zoological science. It is now adopted as the flagship species for conservation in Zanzibar, from the mid-1990s. Other species of fauna found in the park are the Sykes monkey, bush babies, more than 50 species of butterfly and 40 species of birds. The nocturnal Zanzibar tree hyrax, which has four ‘toes’ on its front feet and three on its back, is said to be the first hyrax species that has acclimatized to the forest. As part of the tourism circuit, the park attracts 10% of the over 100,000 visitors t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zanzibar Red Colobus
The Zanzibar red colobus (''Piliocolobus kirkii'') is a species of red colobus monkey endemism, endemic to Unguja, the main island of the Zanzibar Archipelago, off the coast of Tanzania. It is also known as Kirk's red colobus after John Kirk (explorer), Sir John Kirk, the Resident (title), British Resident of Zanzibar who first brought it to the attention of zoology, zoological science. It is now classified as an endangered species and in the mid-1990s was adopted as the flagship species for conservation biology, conservation in Zanzibar. The population is still decreasing, and conservationists are attempting to work with the local government to devise a proper, effective strategy to protect the population and habitat. Challenges include the species' habitat, which is limited to the archipelago. The species has been reclassified three times; it was previously in the genus ''Colobus'', then in the genus ''Procolobus'', and later in the genus ''Piliocolobus''. Evolutionary history ...

Zanzibar Leopard
The Zanzibar leopard is an African leopard (''Panthera pardus pardus'') population on Unguja Island in the Zanzibar archipelago, Tanzania, that is considered extirpated due to persecution by local hunters and loss of habitat. It was the island's largest terrestrial carnivore and apex predator. Increasing conflict between people and leopards in the 20th century led to the demonization of the Zanzibar leopard and determined attempts to exterminate it. Efforts to develop a leopard conservation program in the mid-1990s were shelved when wildlife researchers concluded that there was little prospect for the population's long-term survival. In 2018, a leopard was recorded by a camera trap, thus renewing hopes for the population's survival, although some experts remain skeptical. Taxonomy The Zanzibar leopard was described as a leopard subspecies by Reginald Innes Pocock, who proposed the scientific name ''Panthera pardus adersi'' in 1932. Following molecular genetic analysis of leo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Level Rise
Globally, sea levels are rising due to human-caused climate change. Between 1901 and 2018, the globally averaged sea level rose by , or 1–2 mm per year on average.IPCC, 2019Summary for Policymakers InIPCC Special Report on the Ocean and Cryosphere in a Changing Climate .-O. Pörtner, D.C. Roberts, V. Masson-Delmotte, P. Zhai, M. Tignor, E. Poloczanska, K. Mintenbeck, A. Alegría, M. Nicolai, A. Okem, J. Petzold, B. Rama, N.M. Weyer (eds.) Cambridge University Press, Cambridge, UK and New York, NY, USA. https://doi.org/10.1017/9781009157964.001. This rate is accelerating, with sea levels now rising by 3.7 mm per year. Climate scientists expect further acceleration during the 21st century. Climate change heats (and therefore expands) the ocean and melts land-based ice sheets and glaciers. Between 1993 and 2018, the thermal expansion of water contributed 42% to sea level rise; melting of temperate glaciers, 21%; Greenland, 15%; and Antarctica, 8%. Over the next 2 ...

Ice Age
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the Quaternary glaciation. Individual pulses of cold climate within an ice age are termed ''glacial periods'' (or, alternatively, ''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called '' interglacials'' or ''interstadials''. In glaciology, ''ice age'' implies the presence of extensive ice sheets in both northern and southern hemispheres. By this definition, Earth is currently in an interglacial period—the Holocene. The amount of anthropogenic greenhouse gases emitted into Earth's oceans and atmosphere is predicted to prevent the next glacial period for th ...

Eastern Arc Mountains
The Eastern Arc Mountains is a chain of mountains found in Kenya and Tanzania. The chain runs from northeast to southwest, with the Taita Hills being in Kenya and the other ranges being in Tanzania. They are delimited on the southwest by the fault complex represented by the Makambako Gap that separates them from the Kipengere Range. To the northeast, they are delimited by more recent volcanism represented by Mount Kilimanjaro. The chain is considered a Tentative World Heritage Site. Mountain ranges The Eastern Arc Mountains forms a roughly crescent-shaped arc and consists of: # Taita Hills # North and South Pare Mountains # East and West Usambara Mountains # Nguru Mountains # Ukaguru Mountains # Uluguru Mountains # Uvidunda Mountains # Rubeho Mountains # Malundwe Mountain # Udzungwa Mountains # Mahenge Mountains Geology These mountain ranges are the oldest in East Africa, and though physically separated from each other, share a similar geomorphology and ecology. They were for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lowe's Servaline Genet
The servaline genet (''Genetta servalina'') is a genet species native to Central Africa. As it is widely distributed and considered common, it is listed as Least Concern on the IUCN Red List.
