Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

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] |
Charming Thicket Rat
The charming thicket rat (''Thamnomys venustus'') is a species of rodent in the family Muridae. It is described as data deficient as ''Thamnomys schoutedeni''. It is found in Democratic Republic of the Congo, Rwanda, and Uganda. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss 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 .... References * Dieterlen, F. 2004.Thamnomys schoutedeni 2006 IUCN Red List of Threatened Species.

Murinae
The Old World rats and mice, part of the subfamily Murinae in the family Muridae, comprise at least 519 species. Members of this subfamily are called murines. In terms of species richness, this subfamily is larger than all mammal families except the Cricetidae and Muridae, and is larger than all mammal orders except the bats and the remainder of the rodents. Description The Murinae are native to Africa, Europe, Asia, and Australia. They are terrestrial placental mammals. They have also been introduced to all continents except Antarctica, and are serious pest animals. This is particularly true in island communities where they have contributed to the endangerment and extinction of many native animals. Two prominent murine species have become vital laboratory animals: the brown rat and house mouse are both used as medical subjects. The murines have a distinctive molar pattern that involves three rows of cusps instead of two, the primitive pattern seen most frequently in ...

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] |

Guy Dollman
Captain John Guy Dollman BA, Linnean Society of London, FLS (4 September 1886 – 21 March 1942), known as Guy Dollman, was a British zoologist and Linnaean taxonomy, taxonomist. Dollman's tree mouse and Dollman's vlei rat are named after him. Life and work Elder son of the artist John Charles Dollman, Guy Dollman was born on 4 September 1886 and attended St Paul's School (London), St Paul's School, winning a scholarship to study at St John's College, Cambridge. In February 1907, while still a student, he was employed by the Department of Zoology at the British Museum (Natural History), where he spent most of his working life as Assistant Keeper of Mammals. In 1912, on an expedition to Vietnam, he discovered and named the Tonkin snub-nosed langur. He joined the British Army in 1915, and obtained a commission in the 19th London Regiment. He did not see active service abroad during World War I as he was injured in a bomb accident. He returned to the museum in 1919. He was a member ...

Hatt's Thicket Rat
Hatt's thicket rat (''Thamnomys major''), is a species of thicket rat indigenous to the northern slopes of Mount Karisimbi, an inactive volcano in North Kivu (Nord-Kivu) province of the Democratic Republic of the Congo (DRC). Since the species is identifiable only via the holotype A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of sever ..., its exact distribution is indeterminable. Contemporary analysis suggests a 'significant' difference in the size of the holotype and '' T. kempi'', where the former also exhibits molar features atypical of the later. Yet other specimens collected from the slopes of Mount Karisimbi, rats that Hatt had considered as examples of ''T. major'', were subsequently described as consistent with ''T. kempi''.

Rodent Genera
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose incisors ...
