Uganda Mangabey
The Uganda mangabey (''Lophocebus ugandae'') is a species of Old World monkey found only in Uganda and in the Minziro Forest Reserve, just over the border in Tanzania. This crested mangabey was previously thought to just be a population of the grey-cheeked mangabey (''L. albigena''). Colin Groves upgraded the Ugandan population to the new species ''L. ugandae'' on 16 February 2007. This species is significantly smaller than the grey-cheeked mangabey, with a shorter skull and smaller face. 2008 was the most recent year in which the International Union for Conservation of Nature assessed the conservation status of ''L. albigena'', describing it as being of least concern, and the status of ''L. ugandae'' has not been assessed separately. Taxonomy In 1978, Colin Groves recognized three subspecies of ''Lophocebus albigena'', namely ''L. a. albigena''; ''L. a. johnstoni''; and ''L. a. osmani''. Three decades later, in 2007, he raised these subspecies to full species rank on phyloge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paul Matschie
Paul Matschie Paul Matschie (11 August 1861, Brandenburg an der Havel – 7 March 1926, Friedenau) was a German zoologist. He studied mathematics and natural sciences at the Universities of Halle and Berlin, afterwards working as an unpaid volunteer at the Berlin Zoological Museum under Jean Cabanis (1816–1906). In 1892 he was in charge of the department of mammals at the museum, later becoming a curator (1895), and in 1902 attaining the title of professor. In 1924 he was appointed second director at the museum. During the years 1891–93, he described 11 new species of reptiles. A species of gecko, '' Hemidactylus matschiei'' ( Tornier, 1901), is named in his honor. Matschie organized the fifth International Congress of Zoologists in Berlin and was for some years co-editor of the journal ''Natur und Haus''. Matschie's tree-kangaroo (''Dendrolagus matschiei'') and Matschie's galago (''Galago matschiei'') are two species of mammals which bear his name. Selected writings ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Uganda
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] |
Primates Of Africa
Primates are a diverse order of mammals. They are divided into the strepsirrhines, which include the lemurs, galagos, and lorisids, and the haplorhines, which include the tarsiers and the simians (monkeys and apes, the latter including humans). Primates arose 85–55 million years ago first from small terrestrial mammals, which adapted to living in the trees of tropical forests: many primate characteristics represent adaptations to life in this challenging environment, including large brains, visual acuity, color vision, a shoulder girdle allowing a large degree of movement in the shoulder joint, and dextrous hands. Primates range in size from Madame Berthe's mouse lemur, which weighs , to the eastern gorilla, weighing over . There are 376–524 species of living primates, depending on which classification is used. New primate species continue to be discovered: over 25 species were described in the 2000s, 36 in the 2010s, and three in the 2020s. Primates have large brai ...

Lophocebus
The crested mangabeys are West African Old World monkeys belonging to the genus ''Lophocebus''. They tend to have dark skin, eyelids that match their facial skin, and crests of hair on their heads. Another genus of mangabeys, ''Cercocebus'', was once thought to be very closely related, so much so that all the species were placed in one genus. However, ''Lophocebus'' species are now understood to be more closely related to the baboons in genus ''Papio'', while the ''Cercocebus'' species are more closely related to the mandrill. In 2006, the highland mangabey was moved from ''Lophocebus'' to a new genus, ''Rungwecebus The kipunji (''Rungwecebus kipunji''), also known as the highland mangabey, is a species of Old World monkey that lives in the highland forests of Tanzania.

Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Elaeis Guineensis
''Elaeis guineensis'' is a species of palm commonly just called oil palm but also sometimes African oil palm or macaw-fat. It is the principal source of palm oil. It is native to west and southwest Africa, specifically the area between Angola and the Gambia; the species name, ''guineensis'', refers to the name for the area, Guinea, and not the modern country now bearing that name. The species is also now naturalised in Madagascar, Sri Lanka, Malaysia, Indonesia, Central America, Cambodia, the West Indies, and several islands in the Indian and Pacific Oceans. The closely related American oil palm ''Elaeis oleifera'' and a more distantly related palm, ''Attalea maripa'', are also used to produce palm oil. ''E. guineensis'' was domesticated in West Africa along the south-facing Atlantic coast. There is insufficient documentation and insufficient research to make any guesses as to when this occurred. Human use of oil palms may date as far back as 5,000 years in Egypt; in the late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phoenix (plant)
''Phoenix'' is a genus of 14 species of Arecaceae, palms, native plant, native to an area starting from the Canary Islands in the west, across northern and central Africa, to the extreme southeast of Europe (Crete), and continuing throughout southern Asia from Turkey east to southern China and Malaysia. The diverse habitats they occupy include swamps, deserts, and mangrove sea coasts. Most ''Phoenix'' species originate in Semi-arid climate, semi-arid regions, but usually occur near high groundwater levels, rivers, or Spring (hydrosphere), springs. The genus is unusual among members of subfamily Coryphoideae in having pinnate, rather than palmate leaves; tribe Caryoteae also have pinnate or bipinnate leaves.Riffle, Robert L. & Craft, Paul (2003) ''An Encyclopedia of Cultivated Palms''. Portland: Timber Press. / The palms were more numerous and widespread in the past than they are at present. Some ''Phoenix'' palms have become naturalised in other parts of the world; in particular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Breadfruit
Breadfruit (''Artocarpus altilis'') is a species of flowering tree in the mulberry and jackfruit family (Moraceae) believed to be a domesticated descendant of ''Artocarpus camansi'' originating in New Guinea, the Maluku Islands, and the Philippines. It was initially spread to Oceania via the Austronesian expansion. It was further spread to other tropical regions of the world during the Colonial Era. British and French navigators introduced a few Polynesian seedless varieties to Caribbean islands during the late 18th century. Today it is grown in some 90 countries throughout South and Southeast Asia, the Pacific Ocean, the Caribbean, Central America and Africa. Its name is derived from the texture of the moderately ripe fruit when cooked, similar to freshly baked bread and having a potato-like flavor. The trees have been widely planted in tropical regions, including lowland Central America, northern South America, and the Caribbean. In addition to the fruit serving as a staple fo ...

Canopy (biology)
In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. In forest ecology, canopy also refers to the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms ( epiphytes, lianas, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Sometimes the term canopy is used to refer to the extent of the outer layer of leaves of an individual tree or group of trees. Shade trees normally have a dense canopy that blocks light from lower growing plants. Observation Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs susp ...
