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.

Vangunu is an island, part of the New Georgia Islands in Western Province, Solomon Islands. It is located between New Georgia and Nggatokae Island. To the north and east of the island is Marovo Lagoon. The island has an area of 509 square kilometres (197 sq mi).

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 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 Guadalcanal monkey-faced bat or Guadalcanal flying monkey is a megabat endemic to Solomon Islands. It is listed as an endangered species. In 2013, Bat Conservation International listed this species as one of the 35 species of its worldwide priority list of conservation.

The Biak–Numfoor rain forests is a tropical moist forest ecoregion in Indonesia. The ecoregion covers the islands of Biak, Supiori, Numfoor, and several smaller islands, which lie in Cenderawasih Bay north of Yapen and New Guinea.

The Vangunu giant rat, locally known as the vika, is a giant arboreal species of rodent in the family Muridae. The rat was discovered in the island of Vangunu in the Solomon Islands in 2015, after years of searching based on local stories, and described in 2017. It was identified as a new species on the basis of its skull, skeleton and a detailed DNA analysis. The single individual initially collected from a felled tree measured 46 cm (18 in) long, weighed between 0.5 and 1.0 kg and had orange-brown fur. Its diet is believed to include thick-shelled nuts like ngali nuts and coconuts, and probably fruits. The species is likely to be designated critically endangered, due to the small amount of forest habitat remaining on the island and ongoing logging. In 2021, the species was observed in the wild for the first time, with at least four individuals being observed via camera trap in Vangunu's last remaining lowland primary forest. They are highly threatened by proposed logging plans for their remaining habitat.

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.
