Jentink's Duiker
Jentink's duiker (''Cephalophus jentinki''), also known as ''gidi-gidi'' in Krio and ''kaikulowulei'' in Mende, is a forest-dwelling duiker found in the southern parts of Liberia, southwestern Côte d'Ivoire, and scattered enclaves in Sierra Leone. It is named in honor of Fredericus Anna Jentink. Jentink's duikers stand around tall at the shoulder and weigh about , making them the largest species of the duikers. They are gray from the shoulders back and dark black from the shoulders forward. A white band goes over the shoulders, between the two colours and joining the white undersides. Jentink's duikers have long, thin horns, which curl back a little at the ends, and reach between . Jentink's duikers live mainly in very thick rainforest, where they eat fruit, flowers, and leaves which have fallen from the canopy, as well as stems of seedlings, roots, and, to the annoyance of local farmers, palm nuts, mangos, and cocoa pods. They are nocturnal and shelter during the day in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oldfield Thomas
Michael Rogers Oldfield Thomas (21 February 1858 – 16 June 1929) was a British zoologist. Career Thomas worked at the Natural History Museum on mammals, describing about 2,000 new species and subspecies for the first time. He was appointed to the museum secretary's office in 1876, transferring to the zoological department in 1878. In 1891, Thomas married Mary Kane, daughter of Sir Andrew Clark, heiress to a small fortune, which gave him the finances to hire mammal collectors and present their specimens to the museum. He also did field work himself in Western Europe and South America. His wife shared his interest in natural history, and accompanied him on collecting trips. In 1896, when William Henry Flower took control of the department, he hired Richard Lydekker Richard Lydekker (; 25 July 1849 – 16 April 1915) was an English naturalist, geologist and writer of numerous books on natural history. Biography Richard Lydekker was born at Tavistock Square in London. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...

New Latin Languages
The Romance languages, sometimes referred to as Latin languages or Neo-Latin languages, are the various modern languages that evolved from Vulgar Latin. They are the only extant subgroup of the Italic languages in the Indo-European language family. The five most widely spoken Romance languages by number of native speakers are Spanish (489 million), Portuguese (283 million), French (77 million), Italian (67 million) and Romanian (24 million), which are all national languages of their respective countries of origin. By most measures, Sardinian and Italian are the least divergent from Latin, while French has changed the most. However, all Romance languages are closer to each other than to classical Latin. There are more than 900 million native speakers of Romance languages found worldwide, mainly in the Americas, Europe, and parts of Africa. The major Romance languages also have many non-native speakers and are in widespread use as linguae francae.M. Paul Lewis,Summary by la ...

Generic Name (biology)
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demonstr ...

Scientific 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 zoolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bovidae
The Bovidae comprise the biological family of cloven-hoofed, ruminant mammals that includes cattle, bison, buffalo, antelopes, and caprines. A member of this family is called a bovid. With 143 extant species and 300 known extinct species, the family Bovidae consists of 11 (or two) major subfamilies and thirteen major tribes. The family evolved 20 million years ago, in the early Miocene. The bovids show great variation in size and pelage colouration. Excepting some domesticated forms, all male bovids have two or more horns, and in many species, females possess horns, too. The size and shape of the horns vary greatly, but the basic structure is always one or more pairs of simple bony protrusions without branches, often having a spiral, twisted or fluted form, each covered in a permanent sheath of keratin. Most bovids bear 30 to 32 teeth. Most bovids are diurnal. Social activity and feeding usually peak during dawn and dusk. Bovids typically rest before dawn, during midday ...

Bay Duiker
The bay duiker (''Cephalophus dorsalis''), also known as the black-striped duiker and the black-backed duiker, is a forest-dwelling duiker native to western and southern Africa. It was first described by British zoologist John Edward Gray in 1846. Two subspecies are identified. The bay duiker is reddish-brown and has a moderate size. Both sexes reach at the shoulder. The sexes do not vary considerably in their weights, either; the typical weight range for this duiker is . Both sexes have a pair of spiky horns, measuring . A notable feature of this duiker is the well-pronounced solid stripe of black extending from the back of the head to the tail. The bay duiker is a nocturnal animal. It tends to remain solitary, but pairs can also be observed. The leopard is the main predator of this duiker. It mainly prefers fruits, but may also feed on animal matter such as bird eggs. Females may conceive by the age of 18 months. Breeding occurs throughout the year. Gestation lasts about 240 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow-backed Duiker
The yellow-backed duiker (''Cephalophus silvicultor'') is a forest dwelling antelope in the order Artiodactyla from the family Bovidae. Yellow-backed duikers are the most widely distributed of all duikers. They are found mainly in Central and Western Africa, ranging from Senegal to Western Uganda with possibly a few in Gambia. Their range also extends southward into Rwanda, Burundi, Zaire, and most of Zambia. Taxonomy and etymology The scientific name of the yellow-backed duiker is ''Cephalophus silvicultor''. It is the type species of ''Cephalophus'', and placed in the subfamily Cephalophinae and family Bovidae. The species was first described by English botanist Adam Afzelius in the journal ''Nova Acta Regiæ Societatis Scientiarum Upsaliensis'' in 1815. The generic name has possibly originated from the combination of the New Latin word ''cephal'', meaning head, and the Greek word ''lophos'', meaning crest. The specific name ''silvicultor'' is composed by two Latin words: ''s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
