The Labo shrew rat (Rhynchomys labo) is a species of shrewlike rat in the subfamily Murinae. It was discovered at elevations above 1250 m [1] on Mt. Labo of the Bicol Peninsula of Luzon in the Philippines and described in 2019. [2]
The Old World rats and mice, part of the subfamily Murinae in the family Muridae, comprise at least 519 species. Members of this subfamily are called murines. In terms of species richness, this subfamily is larger than all mammal families except the Cricetidae and Muridae, and is larger than all mammal orders except the bats and the remainder of the rodents.
The genus Chrotomys contain a unique group of rodents found only in the Philippines, specifically the islands of Luzon, Mindoro, and Sibuyan. Instead of being predominantly herbivorous or omnivorous like other murines, these rats feed predominantly on invertebrates although they do eat some vegetable matter. This vermivory is probably the result of a rat-like animal moving into an ecological niche usually filled by shrews. Shrews and other insectivores are absent on these Philippine islands.
Batomys is a genus of rodent endemic to the Philippines. It has six extant described species.
Mount Isarog is an active stratovolcano located in the province of Camarines Sur, Philippines, on the island of Luzon. The mountain has active fumaroles and hot springs. It has an elevation of 2,011 m (6,598 ft) above mean sea level.
The cloud rats or cloudrunners are a tribe (Phloeomyini) of arboreal and nocturnal herbivorous rodents endemic to the cloud forests of the Philippines. They belong to the family Muridae and include five genera: Batomys, Carpomys, Crateromys, Musseromys, and Phloeomys. They range in size from as large as 50 cm (20 in) to as small as 74 mm (2.9 in). Cloud rats are threatened by habitat loss and illegal hunting. Several species are endangered or critically endangered.
The shrewlike rats, genus Rhynchomys, also known as the tweezer-beaked rats are a group of unusual Old World rats found only on the island of Luzon in the Philippines. They look a great deal like shrews and are an example of convergent evolution. Shrewlike rats evolved to be vermivores (worm-eaters) and insectivores feeding on soft-bodied invertebrates associated with leaf litter.
The Luzon montane forest mouse is a species of rodent in the family Muridae, from the genus Apomys. It occurs only in the Philippines, where it has been found on the large northern island Luzon. It is most closely related to the large Mindoro forest mouse, which occurs on Mindoro. There may be another related species in the Sierra Madre, but this species is yet undescribed. The Luzon montane forest mouse is a relatively large, ground-dwelling rat with a tail that is quite short for its genus.
Archboldomys, the shrew-mice, are a genus of rodents in the family Muridae. They are carnivores that feed on invertebrates much like shrews do. An apparently smaller relatives of the true shrew-rats Chrotomys and Rhynchomys, Archboldomys are somewhat convergent to the more distantly related Crunomys.
Phloeomys, the slender-tailed cloud rats, is a genus of large rodents in the family Muridae. Both species in this genus are endemic to the island of Luzon in the Philippines. Although their tail is covered by hairs, it is considerably less dense and shorter than in the rarer bushy-tailed cloud rats that also inhabit the Philippines.
The Isarog shrew-rat or Mount Isarog shrew-rat is a species of rodent in the family Muridae. It is found only in the Philippines.
The Mount Data shrew-rat is a species of rodent in the family Muridae. It is found only in the Philippines.
A shrew rat or shrew-rat is not a true rat but a rodent that resembles a shrew in physical form and, presumably, lifestyle. There are twelve known species distributed across seven known genera, all from island southeast Asia, specifically the Indonesian island of Sulawesi and several islands of the Philippines:
Paucidentomys is a genus of rodents of a type commonly known as shrew-rats which was discovered in 2012 in a remote rainforest on the Indonesian island, Sulawesi. The genus is monotypic, consisting of the species Paucidentomys vermidax, or the edented Sulawesi rat. The Latin name may also be translated to its other common name "few-toothed worm-eating rat", referring to the fact that they have only two teeth and may live exclusively on a diet of earthworms.
The Banahao shrew-rat is a species of rodent in the genus Rhynchomys. It was described in 2007.
The Tapulao shrew-rat is a rodent in the subfamily Murinae. It was described in 2007.
Soricomys, the shrew-mice, are a genus of rodents in the family Muridae. They are carnivores that feed on invertebrates much like shrews do. An apparently smaller relatives of the true shrew-rats Chrotomys and Rhynchomys, Soricomys are somewhat convergent to the more distantly related Crunomys.
The Mingan shrew rat is a species of shrewlike rat in the subfamily Murinae. It was discovered at elevations above 1450 m on Mt. Mingan of the central Sierra Madre of Luzon in the Philippines and described in 2019.
Danilo S. Balete, also known as Danny Balete, was a Filipino zoologist and biologist. His is known for his work on the Philippines' endemic mammal species. He pursued the question of what determines species diversity. The research by Balete and his team overturned previously held notions that diversity decreased in mountainous regions, showing that harsh environments could generate, rather than suppress, species diversity.
Hydromyini is a very large, diverse tribe of muroid rodents in the subfamily Murinae. They are the dominant native rodents in Australasia and one of only two native rodent groups there, the other being the R. fuscipes group of the genus Rattus in the tribe Rattini. They are also found in parts of Southeast Asia.
Rattini is a very large, diverse tribe of muroid rodents in the subfamily Murinae. They are found throughout Asia and Australasia, with a few species ranging into Europe and northern Africa. The most well-known members of this group are the true rats, several species of which have been introduced worldwide.
