Tufted Ground Squirrel
The tufted ground squirrel or groove-toothed squirrel (''Rheithrosciurus macrotis'') is a species of rodent in the family Sciuridae. It is the sole species in the genus ''Rheithrosciurus''. It is found only on the island of Borneo. Confirmed elements of its diet include nuts, seeds and insects, for which it has been filmed foraging on the forest floor. Description The squirrel's head and body measure about long, with the tail measuring a further long. It weighs about . Its incisors have 7-10 distinctive longitudinal grooves. Its skull is also distinctive, being longer and flatter than most squirrels. The animal's dorsum is predominantly brown with a reddish tone, and it has unusually hairy ears with large red to dark brown tufts. A longitudinal stripe of a white to buff to yellow colour, sometimes accompanied by a dark brown stripe, runs along the flank. ''Rheithrosciurus'' is noted for having the largest known tail to body size ratio of any mammal, with the volume of its tail ...

John Edward Gray
John Edward Gray (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Banks (naturalist)
Edward (Bill) Banks (1903–1988) was a British administrator, amateur naturalist and museum curator. Life Banks was born in Newport, Wales. He was the only son of Reginald Clare Banks, a colliery proprietor, but had three older sisters and went on to study zoology at Oxford University. In 1925 Banks entered the Sarawak Service and served as a District Officer during the period of the White Rajahs. He was also Curator of the Sarawak Museum in Kuching from 1925 to 1945. During the Japanese occupation of Sarawak in the Second World War, Banks was interned at Batu Lintang camp near Kuching. Banks retired in 1950. A collection of Banks' papers are in the Papers of the Brooke Family of Sarawak (1941–1981), held in the Rhodes House Library in Oxford, England.Ooi 1998, 535-6 Selected publications Articles *1931 "A trip through the Murut country.

Mammals Described In 1857
A mammal () is a vertebrate animal of the class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, cats, Canidae, do ...

Rodents Of Malaysia
Rodents (from Latin , 'to gnaw') are mammals of the Order (biology), order Rodentia ( ), which are characterized by a single pair of continuously growing incisors in each of the upper and Mandible, lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for 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/ricochetal (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 Mouse, mice, rats, squirrels, prairie dogs, porcupines, beavers, Cavia, guinea pigs, and hamsters. Once included wi ...

Endemic Fauna Of Borneo
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Tree Squirrels
Tree squirrels are the members of the squirrel family (Sciuridae) commonly just referred to as "squirrels". They include more than 100 arboreal species native to all continents except Antarctica and Oceania. They do not form a single natural, or monophyletic, group; they are variously related to others in the squirrel family, including ground squirrels, flying squirrels, marmots, and chipmunks. The defining characteristic used to determine which species of Sciuridae are tree squirrels is dependent on their habitat rather than their physiology. Tree squirrels live mostly among trees, as opposed to those that live in burrows in the ground or among rocks. An exception is the flying squirrel that also makes its home in trees, but has a physiological distinction separating it from its tree squirrel cousins: special flaps of skin called patagia, acting as glider wings, which allow gliding flight. The best-known genus of tree squirrels is ''Sciurus'', which includes the eastern gra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gunung Palung National Park
Mount Palung National Park () lies on the island of Borneo, in the Indonesian province of West Kalimantan, north of Ketapang and east of Sukadana. History Mount Palung was first protected in 1937 as a forest nature reserve covering . In 1981, the size was increased to and its status raised to a wildlife reserve, and on 24 March 1990 the area became a national park. Geography The park is notable for its diversity of habitat types, ranging from mangrove and freshwater swamp forest, to lowland alluvial (empran bench) forest, to montane forest, and for its diversity of wildlife. It is one of only a handful of parks in the world where orangutans can be seen in the wild. A research station (Cabang Panti) was established at the western foot of the main Mount Palung mountains in 1985, and is owned and operated by the park management authority. Research there has contributed significantly to our understanding of Borneo forest biology. Illegal, non-mechanized, 'hand logging' has b ...
