Thalpomys Lasiotis
The hairy-eared cerrado mouse (''Thalpomys lasiotis'') or hairy-eared akodont, is a rodent species from South America. It is found in the cerrado grassland of Brazil. Description The hairy-eared cerrado mouse has a head-and-body length of less than and is generally smaller than the only other species in the genus, the cerrado mouse (''Thalpomys cerradensis''). The two are similar in appearance, but the hairy-eared mouse has a more intense colour and longer, more lax fur.

Akodontini
Akodontini is the second most speciose rodent tribe of the subfamily Sigmodontinae. It includes at least 106 living species in 19 genera and is distributed mainly in the southern half of South America, with only two genera extending into Guyana ('' Podoxymys'') and Venezuela (''Necromys''). It also includes genera previously placed in tribe Scapteromyini. The following genera are now generally recognized: *''Akodon'' *'' Bibimys'' *'' Blarinomys'' *''Brucepattersonius'' *'' Deltamys'' *'' Juscelinomys'' *'' Kunsia'' *'' Lenoxus'' *''Necromys'' (previously ''Bolomys'' or ''Cabreramys'') *'' Neomicroxus'' *''Oxymycterus'' *'' Podoxymys'' *''Scapteromys'' *''Thalpomys'' *'' Thaptomys'' ''Chalcomys'', ''Hypsimys'', and ''Microxus'' have been synonymized under the genus ''Akodon''. Several other genera were previously placed in Akodontini, but are now placed in a separate tribe Abrotrichini Abrotrichini, also known as the Andean clade or southern Andean clade,Musser and Carleton, 2 ...

Oldfield Thomas
Michael Rogers Oldfield Thomas (21 February 1858 – 16 June 1929) was a British zoologist. Career Thomas worked at the 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, 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 imperialism. "You and I in our scientific lives have seen th ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency ...

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, wh ...

Cricetidae
The Cricetidae are a family of rodents in the large and complex superfamily Muroidea. It includes true hamsters, voles, lemmings, muskrats, and New World rats and mice. At almost 608 species, it is the second-largest family of mammals, and has members throughout the Americas, Europe and Asia. Characteristics The cricetids are small mammals, ranging from just in length and in weight in the New World pygmy mouse up to and in the muskrat. The length of their tails varies greatly in relation to their bodies, and they may be either furred or sparsely haired. The fur of most species is brownish in colour, often with a white underbelly, but many other patterns exist, especially in the cricetine and arvicoline subfamilies. Like the Old World mice, cricetids are adapted to a wide range of habitats, from the high Arctic to tropical rainforests and hot deserts. Some are arboreal, with long balancing tails and other adaptations for climbing, while others are semiaquatic, with w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerrado
The ''Cerrado'' (, ) is a vast ecoregion of tropical savanna in eastern Brazil, particularly in the states of Goiás, Mato Grosso do Sul, Mato Grosso, Tocantins, Minas Gerais, and the Federal District. The core areas of the Cerrado biome are the Brazilian highlands – the ''Planalto''. The main habitat types of the Cerrado consist of forest savanna, wooded savanna, park savanna and gramineous-woody savanna. The ''Cerrado'' also includes savanna wetlands and gallery forests. The second largest of Brazil's major habitat types, after the Amazonian rainforest, the Cerrado accounts for a full 21 percent of the country's land area (extending marginally into Paraguay and Bolivia). The first detailed European account of the Brazilian cerrados was provided by Danish botanist Eugenius Warming (1892) in the book ''Lagoa Santa'', : The above is the original. There are other, later French and Portuguese translations not listed here. in which he describes the main features of the ce ...

Tropical Savanna
Tropical and subtropical grasslands, savannas, and shrublands is a terrestrial biome defined by the World Wide Fund for Nature. The biome is dominated by grass and/or shrubs located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes. Description Grassland is dominated by grass and other herbaceous plants. Savanna is grassland with scattered trees. Shrubland is dominated by woody or herbaceous shrubs. Large expanses of land in the tropics do not receive enough rainfall to support extensive tree cover. The tropical and subtropical grasslands, savannas, and shrublands are characterized by rainfall levels between per year. Rainfall can be highly seasonal, with the entire year's rainfall sometimes occurring within a couple of weeks. African savannas occur between forest or woodland regions and grassland regions. Flora includes acacia and baobab trees, grass, and low shrubs. Acacia trees lose their leaves in the dry season to conserve moisture, while t ...
