As their common name indicates, they are notable for their acoustic communication. They are insectivorous. The two species show substantial divergence in behaviour and reproduction,Hooper, E.

Alston's Brown Mouse
Alston's brown mouse, also called Alston's singing mouse, short-tailed singing mouse, or singing mouse (''Scotinomys teguina''), is a species of rodent in the family Cricetidae. It is found in Central America, from Chiapas, Mexico, to western Panama. This species produces vocalizations in both the sonic and ultrasonic range that are thought to be an important component of its communication behavior.Reid, Fiona A. (1997): "''A field guide to the mammals of central america and southeast mexico''. Oxford University Press, New York Distribution and habitat ''S. teguina'' is exclusively found in the highland forests of southern North America and throughout Central America, from Chiapas, Mexico to western Panama, at elevations between 1100 and 2950 meters.Hooper, Emmet T., and Carleton Michael D.

Scotinomys Xerampelinus
The Chiriqui brown mouse (''Scotinomys xerampelinus''), also known as the long-tailed singing mouse, is a species of rodent in the family Cricetidae. It is found in cloud forest and paramo at elevations of 2100 to 3400 m in Costa Rica and Panama. Male Chiriqui brown mice sing to attract mates and to warn off other males from their territories. Their songs also serve to repel members of the related, smaller, competing species, '' S. teguina''. Additionally, the length and aggression of male Chiriqui brown mice's calls are modulated by androgen An androgen (from Greek ''andr-'', the stem of the word meaning ) is any natural or synthetic steroid hormone that regulates the development and maintenance of male characteristics in vertebrates by binding to androgen receptors.

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] |

Edward Richard Alston
Edward Richard Alston (1 December 1845 – 7 March 1881) was a Scottish zoologist. Alston was born at Stockbriggs, near Lesmahagow, on 1 December 1845. He was delicate in youth, so chiefly self-educated at home. He very early contributed to ''The Zoologist'' and various Scottish magazines, and ultimately became an acknowledged authority on mammalia and birds. His principal papers in the ''Proceedings of the Zoological Society'' (1874–80) are upon rodents, especially American squirrels (1878 and 1879). The division Mammalia in Salvin and Godman's ''Biologia Centrali-Americana'' was written by him, though its publication was incomplete at his death. In 1880, he was elected zoological secretary of the Linnean Society The Linnean Society of London is a learned society dedicated to the study and dissemination of information concerning natural history, evolution, and taxonomy. It possesses several important biological specimen, manuscript and literature collec ..., which office ... [...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 ...

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 over 870 species, it is either the largest or 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 ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
