Bornean Smooth-tailed Treeshrew
The Bornean smooth-tailed treeshrew (''Dendrogale melanura'') is a species of treeshrew in the family Tupaiidae. It is endemic to Borneo. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss. Description The head and body length of the species is , with tail length . The body mass is about . Upper parts of the small body are dark brown, while the under parts are orange-buff with gray bases, and shiny black with reddish streaking along the sides. It has a short snout, with large ear flaps. Prominent orange-brown rings exist around the eyes, with weakly marked facial streaks present on both side of the face, extending from the snout to ears. No shoulder streaks are present. The claws are notably sharp. The thin tail is covered with fine, smooth hair, with darkening towards the tip. ''D. m. melanura'' has darker colour above and more reddish below than ''D. m. baluensis''.Francis, C.M. & Payne, J. (2005). A field guide to the mammals of Borneo. ...

Oldfield Thomas
Michael Rogers Oldfield Thomas (21 February 1858 – 16 June 1929) was a British zoologist. Career Thomas worked at the Natural History Museum, London, 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, 1st Baronet, 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 to rearrange the exhibitions, allowing Thomas to concentrate on these new specimens. Thomas viewed his taxonomy efforts from the scope of British impe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects
Insects (from Latin ') are hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes, and a pair of antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a brain and a ventral nerve cord. Most insects reproduce by laying eggs. Insects breathe air through a system of paired openings along their sides, connected to small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in vessels, and some circulates in an open hemocoel. Insect vision is mainly through their compound eyes, with additional small ocelli. Many insects can hear, using tympanal organs, which may be on the legs or other parts of the b ...

Taxa Named By Oldfield Thomas
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Described In 1892
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 middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,640 extant species of mammals have been described and divided into 27 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, moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including cats, dogs, and seals). Mammals are the only living members of Synapsida; this clade, together with Sauropsida (reptiles and birds), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of Malaysia
The wildlife of Malaysia is diverse, with Malaysia being a Megadiverse countries, megadiverse country. Most of the country is covered in rainforest, which hosts a huge biodiversity, diversity of plant and animal species. There are approximately 361 mammal species, 694 #Birds, bird species, 250 reptile species, and 150 frog species found in Malaysia. Its large marine territory also holds a great diversity of life, with the country's coastal waters comprising part of the Coral Triangle. Terrestrial fauna Malaysia is estimated to contain 20% of the world's animal species, and includes some of the most biodiverse areas on the planet. High levels of endemism are found in the diverse forests of Malaysian Borneo's mountains, as populations are isolated from each other by lowland forest.

Mammals Of Borneo
The mammal species of Borneo include 288 species of terrestrial and 91 species of marine mammals recorded within the territorial boundaries of Brunei, Indonesia and Malaysia. The terrestrial mammals are dominated by the chiroptera (102 species of bats) and rodents (61 species of rats and mice). Introduction The high diversity and endemicity of mammals is related to the many niches found in the tropical rain forest of Borneo and past Pleistocene events within the Sundaland region. During interglacial and post-glacial periods, there was migration of animal from the Asian mainland into Borneo and into Sulawesi via the Philippines. Due to lack of favourable habitats and small founder population, some species of animals have become extinct and others have radiated into endemic species. Of the 57 mammal species that were identified from archaeological remains in the Niah Caves, Sarawak, 13 were bats. Four of these were megachiropterans, '' Pteropus vampyrus'', '' Rousettus amplexicaudat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Agricultural Expansion
Agricultural expansion describes the growth of agricultural land ( arable land, pastures, etc.) especially in the 20th and 21st centuries. The agricultural expansion is often explained as a direct consequence of the global increase in food and energy Energy () is the physical quantity, quantitative physical property, property that is transferred to a physical body, body or to a physical system, recognizable in the performance of Work (thermodynamics), work and in the form of heat and l ... requirements due to population growth (both which in turn have been attributed to agricultural expansion itself), with an estimated expectation of 10 billion people on Earth by end of this century. It is foreseen that most of the world's non-agrarian ecosystems (terrestrial ecosystem, terrestrial and aquatic ecosystem, aquatic) will be environmental impact, affected adversely, from habitat loss, land degradation, overexploitation, and other problems.

Loss Of Habitat
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduction of invasive species, ecosystem nutrient depletion, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they ...
