Rio Guaporé Mouse
The Rio Guaporé mouse or Guaporé akodont (''Juscelinomys guaporensis'') was formerly considered a rodent species in the family Cricetidae. It is known only from a small savanna in eastern Bolivia , image_flag = Bandera de Bolivia (Estado).svg , flag_alt = Horizontal tricolor (red, yellow, and green from top to bottom) with the coat of arms of Bolivia in the center , flag_alt2 = 7 × 7 square p ... near the Rio Guaporé. However, in 2012 it was described as being conspecific with '' J. huanchacae''.

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 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 Mouse, mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and ...

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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in for ...

Guaporé River
Guaporé River ( pt, Rio Guaporé, es, Río Iténez) is a river in western Brazil and northeastern Bolivia. It is long; of the river forms the border between Brazil and Bolivia. The Guaporé River is part of the Madeira River basin, which eventually empties into the Amazon River. The Guaporé River crosses the eastern part of the Beni savanna region. It forms the border of the Guaporé Biological Reserve, and is fed by rivers originating in the reserve, the São Miguel, Branco, São Simão, Massaco and Colorado. About 260 fish species are known from the Guaporé River basin, and about 25 of these are endemic.Hales, J., and P. Petry (2013). Guapore - Itenez'. Freshwater Ecoregions of the World. Retrieved 28 February 2013 While many fish species in the river essentially are Amazonian, the fauna in the Guaporé also has a connection with the Paraguay River The Paraguay River (Río Paraguay in Spanish, Rio Paraguai in Portuguese, Ysyry Paraguái in Guarani) is a major river ...

Juscelinomys Huanchacae
The Huanchaca mouse or Huanchaca akodont (''Juscelinomys huanchacae'') is a rodent species in the family Cricetidae. It is known from savannas in an area at an elevation of in Serrania Huanchaca, Noel Kempff Mercado National Park in eastern Bolivia. Description The Huanchaca mouse is a fairly uniform olive-brown colour, the pelage being about in length along the spine. The individual hairs on the back and flanks have grey bases, dark shafts and either black or yellowish tips. The ventral pelage is grey or yellowish buff. The sides of the muzzle and the chin are pale and the ears are well clad with short, pale-tipped hairs and fringed with pale-coloured hairs. The feet are clad with dark hairs with whitish tips. The tail is well-covered with stiff, dark-coloured hairs on the upper surface and paler hairs underneath. Distribution and habitat This mouse is endemic to eastern Bolivia. It has a rather small range, with between the most widely separated of the four localities from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of Bolivia
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 ...

Juscelinomys
''Juscelinomys'' is a genus of burrowing mice. The name is derived from Brazilian president Juscelino Kubitschek who created the city of Brasilia where the Brasilia burrowing mouse was discovered. There are two living species: * †''J. candango'' Candango mouse * ''J. guaporensis'' Rio Guaporé mouse * ''J. huanchacae'' Huanchaca mouse A fourth species, ''J. talpinus'', is known only from subfossil A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved ... remains. Some authorities treat it as a distinct species or a senior synonym for one or all species in ''Juscelinomys''. References * {{Taxonbar, from=Q910254 Rodent genera ...
