Mesembriomys Macrurus
The golden-backed tree rat (''Mesembriomys macrurus'') is a species of rodent in the family Muridae, found only in Australia. Its native range was across Northern Australia, but it has since become extinct from these regions. It is now only found in remote near-coastal areas in the Kimberley, Western Australia. It is present in the Charnley River–Artesian Range Wildlife Sanctuary. Description Golden-backed tree rats are named for their broad stripe of golden-coloured fur that runs from the top of its head to the base of their tail, of which has a white brush tip. They are nocturnal and arboreal. During day, they sleep in their nests made in hollow trees, dense foliage or among rocks. They range in size from 18 to 34 cm with a 29 to 36 cm tail, and weigh 200-330 grams. Golden-backed tree rats are thought to breed throughout the year, with a gestation period of 48 days and litter size of 2. Their young are weaned at either six or seven weeks old. In captivity, the maximum l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-footed Tree-rat
The black-footed tree-rat (''Mesembriomys gouldii''), also known as Djintamoonga, is one of two endemic Australian rodent species in the genus ''Mesembriomys.'' Both the black-footed tree-rat and its congener, the golden-backed tree-rat ('' M. macrurus''), are found in northern Australia. The species is one of the largest murids found in Australia. Haematological and blood chemistry research has been performed on the black-footed tree-rat to aid in the captive and natural management of Australian native murids held in captivity for conservation purposes. Description The tree-rat has a greyish-brown coat that is shaggy and coarse and has a creamy white underbelly. The hind feet are black with well developed pads and strong sharp claws. They have large ears and a long tail with a brush of white hair at the tip. They grow to a mass of . The head and body length of the tree-rat is typically with a tail length of . Three subspecies of the black-footed tree-rat have been recogn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Early Pleistocene
The Early Pleistocene is an unofficial epoch (geology), sub-epoch in the international geologic timescale in chronostratigraphy, representing the earliest division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently estimated to span the time between 2.580 ± 0.005 annum, Ma (million years ago) and 0.773 ± 0.005 Ma. The term Early Pleistocene applies to both the Gelasian, Gelasian Age and the Calabrian (stage), Calabrian Age. While the Gelasian and the Calabrian have officially been defined by the International Union of Geological Sciences (IUGS) to effectively constitute the Early Pleistocene, the succeeding Chibanian and Tarantian ages have yet to be ratified. These proposed ages are unofficially termed the Middle Pleistocene and Late Pleistocene respectively. The Chibanian provisionally spans time from 773 ka to 126 ka, and the Tarantian from then until the definitive end of the whole Pleistocene, c. 9700 BC in the 10th millennium BC. Notes {{Ge ...

Theodore Sherman Palmer
Theodore Sherman Palmer (January 26, 1868 – July 24, 1955) was an American zoologist. Palmer was born in Oakland, California, and studied at the University of California. He was the son of Henry Austin and Jane Olivia (Day) Palmer, and his mother was the daughter of Sherman Day, granddaughter of Yale President Jeremiah Day, and the great-granddaughter of American founding father Roger Sherman, meaning that Palmer was Sherman's great-great grandson. In 1889, he joined the Division of Economic Ornithology and Mammalogy of the United States Department of Agriculture under Clinton Hart Merriam. In 1891 he was a member of the 1891 Death Valley Expedition and its leader for its first 3 months. He was Assistant Chief of the Department from 1896 to 1902, and then from 1910 to 1914. He became interested in the legislation affecting wildlife, leading a branch of the organization to deal with it from 1902 to 1910 and from 1914 to 1916. He wrote the preliminary draft of the treaty for ... [...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
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 ...

Muridae
The Muridae, or murids, are either the largest or second-largest family of rodents and of mammals, containing approximately 870 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 (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 relat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
