Leptomys
''Leptomys'' is a genus of rodent endemic to New Guinea. It is considered part of the New Guinea Old Endemics, meaning it was part of the first wave of murine rodents to colonize the island. ''Leptomys'' are seen to have minimal adaptations to their aquatic life style. Elongated hind feet accompanied by elongated centre toes suggest the ability to leap. The third molar which is lost is many rodents is retained, albeit smaller. Small eyes and ears can be seen amongst its velvety soft fur.Walkers Mammals, Nowak, 1983 Species * '' Leptomys arfakensis'' Musser, Helgen & Lunde, 2008 * Long-footed water rat, ''Leptomys elegans'' * Ernst Mayr's water rat, ''Leptomys ernstmayri'' * '' Leptomys paulus'' Musser, Helgen & Lunde, 2008 * Fly River water rat The Fly River water rat (''Leptomys signatus'') is a species of rodent in the family Muridae.

Long-footed Water Rat
The long-footed water rat (''Leptomys elegans'') is a species of rodent in the family Muridae. It is found in the mountains of southern Papua New Guinea. Its natural habitat is subtropical or tropical dry forest. Distribution and habitat The long-footed water rat is endemic to the eastern half of the island of New Guinea. Its range includes the Owen Stanley Range, Mount Dayman, Mount Sisa, and Mount Victory in Papua New Guinea, and its altitudinal range extends from . Relatively few specimens of this rat have been observed, and its habitat includes secondary forest and old gardens, and it is presumed to be also present in primary forest. Status No particular threats are known for this species. It is sometimes hunted, presumably for food, but this is unlikely to be of much significance to the species. Previously classified as "critically endangered", the long-footed water rat has been found to have a much wider distribution and to be more plentiful than was once thought and has ...

Leptomys Paulus
''Leptomys paulus'' is a small rodent belonging to the family Muridae endemic to New Guinea. Description ''L. paulus'' has a head and body length of between 117 and 132 mm, and a tail length of between 138 and 163 mm. Its ears are 18 to 23 mm, dark brown in colour and have a few dark hairs, its feet are 31 to 36 mm . It can weigh up to 52 g. Its thick and soft fur is dark reddish brown on dorsal parts, yellowish on its sides and grayish white on the ventral parts. There is a hairless strip of skin that extends from the middle of the shoulders towards the forehead. It has long whiskers (60 mm) and white cheeks with a darker colour around the eyes. The tail is almost hairless with a white tip. Habitat The species has been observed in the tropical low-montane Montane ecosystems are found on the slopes of mountains.

Murine Rodent
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 mu ...

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] |
New Guinea
New Guinea (; Hiri Motu: ''Niu Gini''; , fossilized , also known as Papua or historically ) is the List of islands by area, world's second-largest island, with an area of . Located in Melanesia in the southwestern Pacific Ocean, the island is separated from Mainland Australia, Australia by the wide Torres Strait, though both landmasses lie on the same continental shelf, and were united during episodes of low sea level in the Pleistocene glaciations as the combined landmass of Sahul. Numerous smaller islands are located to the west and east. The island's name was given by Spanish explorer Yñigo Ortiz de Retez during his maritime expedition of 1545 due to the perceived resemblance of the indigenous peoples of the island to those in the Guinea (region), African region of Guinea. The eastern half of the island is the major land mass of the nation of Papua New Guinea. The western half, known as Western New Guinea, forms a part of Indonesia and is organized as the provinces of Pap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 taxonomy (biology), 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. Phylogeneti ...

Rodent Genera
Rodents (from Latin Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area aroun ... , '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 shar ...
