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 but smaller in size. Small eyes and ears can be seen amongst its velvety soft fur.

Rodent
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 i ...

Muridae
The Muridae, or murids, are the largest family of rodents and of mammals, containing approximately 1,383 species, including many species of mice, rats, and gerbils found naturally throughout Eurasia, Africa, and Australia. The name Muridae comes from the Latin ' (genitive '), meaning "mouse", since all true mice belong to the family, with the more typical mice belonging to the genus '' Mus''. Distribution and habitat Murids are found nearly everywhere in the world, though many subfamilies have narrower ranges. Murids are not found in Antarctica or many oceanic islands. Although none of them are native to the Americas, a few species, notably the house mouse and black rat, have been introduced worldwide. Murids occupy a broad range of ecosystems from tropical forests to tundras. Fossorial, arboreal, and semiaquatic murid species occur, though most are terrestrial animals. The extensive list of niches filled by murids helps to explain their relative abundance. Diet and dentiti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernst Mayr
Ernst Walter Mayr (; 5 July 1904 – 3 February 2005) was one of the 20th century's leading evolutionary biologists. He was also a renowned Taxonomy (biology), taxonomist, tropical explorer, ornithologist, Philosophy of biology, philosopher of biology, and History of science, historian of science. His work contributed to the conceptual revolution that led to the Modern synthesis (20th century), modern evolutionary synthesis of Gregor Mendel, Mendelian genetics, systematics, and Charles Darwin, Darwinian evolution, and to the development of the Species, biological species concept. Although Charles Darwin and others posited that multiple species could evolve from a single common ancestor, the mechanism by which this occurred was not understood, creating the ''species problem''. Ernst Mayr approached the problem with a new definition for species. In his book ''Systematics and the Origin of Species'' (1942) he wrote that a species is not just a group of Morphology (biology), morph ...

Foja Mountains
The Foja Mountains (Foja Range, Foya Mountains) ( id, Pegunungan Foja) are located just north of the Mamberamo river basin in Papua, Indonesia. The mountains rise to , and have 3,000 square kilometers of old growth tropical rainforest in the interior part of the range. The Foja forest tract covers 9,712 square kilometers and is the largest tropical forest without roads in the Asia Pacific region. The Foja Range languages are spoken within the mountain range and nearby areas. Geography The Foja Mountains are cooler than the lowlands below because of their elevation, but January and July temperatures still average . The rainy season is from December to March, but the area can receive rain throughout the year. In a typical year, the range receives more than of precipitation. Relative humidity ranges from 73 to 87%. The nearest villages include Sragafareh, Jomen, Beggensabah, Aer Mati, and Dabra.

Papua Province
Papua is a province of Indonesia, comprising the northern coast of Western New Guinea together with island groups in Cenderawasih Bay to the west. It roughly follows the borders of Papuan customary region of Tabi Saireri. It is bordered by the sovereign state of Papua New Guinea to the east, the Pacific Ocean to the north, Cenderawasih Bay to the west, and the provinces of Central Papua and Highland Papua to the south. The province also shares maritime boundaries with Palau in the Pacific. Following the splitting off of twenty regencies to create the three new provinces of Central Papua, Highland Papua, and South Papua on 30 June 2022, the residual province is divided into eight regencies (''kabupaten'') and one city (''kota''), the latter being the provincial capital of Jayapura. The province has a large potential in natural resources, such as gold, nickel, petroleum, etc. Papua, along with four other Papuan provinces, has a higher degree of autonomy level compared to other ...

Mammals Described In 1932
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together wi ...
