The Solomon Islands rain forests are a terrestrial ecoregion covering the Solomon Islands archipelago.
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 earless water rat is a New Guinea rodent, part of the Hydromys group of the subfamily of Old World rats and mice (Murinae). It is the only species in the genus Crossomys. This species is probably most closely related to Baiyankamys. It is still unclear to which species this group is related. It is one of the most aquatically adapted rodents of the world.
The giant white-tailed rat is an Australian rodent native to tropical rainforest of north Queensland, with subspecies occurring in New Guinea and the Aru Islands. It is one of the largest rodents in Australia, reaching up to 1 kg in weight. It is grey-brown above, cream to white below, and has a long, naked tail of which the distal section is white.
The brush-tailed rabbit rat is a species of rodent in the family Muridae. It is found in Australia and Papua New Guinea.
Melomys is a genus of rodents in the family Muridae. Members of this genus live in the wet habitats of northern Australia, New Guinea, Torres Strait Islands and islands of the Indonesian archipelago.
The Bramble Cay melomys, or Bramble Cay mosaic-tailed rat, is a recently extinct species of rodent in the family Muridae and subfamily Murinae. It was an endemic species of the isolated Bramble Cay, a low-lying vegetated coral cay with a habitable area of approximately 5 acres located at the northern tip of the Great Barrier Reef in Australia. Described by researchers as having last been seen in 2009 and declared extinct by the Queensland Government and University of Queensland researchers in 2016, it was formally declared extinct by the International Union for Conservation of Nature (IUCN) in May 2015 and the Australian government in February 2019. Having been the only mammal endemic to the reef, its extinction was described as the first extinction of a mammal species due to anthropogenic climate change.
Poncelet's giant rat or Poncelet's naked-tailed rat is a species of rodent in the family Muridae. It is found on Bougainville Island, part of Papua New Guinea, and nearby Choiseul Island in the Solomon Islands.
Solomys is a genus of rodent in the family Muridae. These large rats, which are all seriously threatened, are native to the Solomon Islands.
The Ugi naked-tailed rat is a poorly known and possibly extinct species of rodent in the family Muridae. It is known from a single specimen collected on Ugi Island in the Solomon Islands.
The Bougainville naked-tailed rat or Bougainville giant rat is a species of rodent in the family Muridae. It is found in Papua New Guinea and the Solomon Islands.
The Isabel naked-tailed rat is a species of rodent in the family Muridae. It is found only on the island of Santa Isabel in the Solomon Islands.
The giant naked-tailed rat is a species of rodent in the family Muridae. It is found in West Papua, Indonesia and Papua New Guinea. It lives in tropical forests, wetlands, and in degraded forests.
The Solomon Archipelago is a terrestrial ecoregion and marine ecoregion in the Pacific Ocean. It includes the tropical ocean waters surrounding most of the Solomon Islands archipelago, and includes Bougainville Island and Buka Island of Papua New Guinea and their surrounding waters.
The Rossel Island melomys is a species of rodent from the family Muridae. It is endemic to Rossel Island in Papua New Guinea, but Flannery (1955) presumed that "it did exist previously on other islands of the group, but has become extinct on all except Rossel." For many years it was seen as a subspecies of the white-bellied mosaic-tailed rat, but is now considered a distinct species. It is listed as data deficient by the IUCN Red List in light of little information on "population status, ecological requirements, and threats". The Rossel Island melomys has not been officially recorded since 1956, but its habitat is still in good condition. The IUCN lists determining population status of the melomys as a "high priority".
Buka Rural LLG is a local-level government (LLG) of comprising Buka Island in the Autonomous Region of Bougainville, Papua New Guinea. Several Northwest Solomonic languages are spoken in the LLG.
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.
