Leptomys arfakensis is a species of rodent in the family of Muridae. It is found in the Arfak Mountains of West Papua, Indonesia. [1]
The Muridae, or murids, are the largest family of rodents and of mammals, containing approximately 1,383 species, including many species of mice, rats, and gerbils found naturally throughout Eurasia, Africa, and Australia.
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.
Apodemus is a genus of Muridae. The name is unrelated to that of the Mus genus, instead being derived from the Greek ἀπό-δημος.
Papuacedrus papuana is a species in the conifer family Cupressaceae, the sole species in the genus Papuacedrus. Some botanists do not consider this species as forming a distinct genus, but include it in the related genus Libocedrus. It is native to New Guinea and to the Indonesian Province of Maluku.
Batomys is a genus of rodent endemic to the Philippines. It has six extant described species.
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.
Gymnosphaera biformis, synonyms Alsophila biformis and Cyathea biformis, is a species of tree fern native to New Guinea and the Maluku Islands, where it grows against trees in mossy forest and rain forest at elevations of 850–2200 m. The climbing trunk is very thin, only 1–2 cm in diameter, but can reach 3 m in height. The apex of the trunk is covered in scales. Two types of fronds are produced, simple pinnate fronds, which are sterile, and bipinnate fronds, which may be fertile. The stipe is smooth, glossy and very dark, almost to the point of being black. It is covered at the base with long, very dark scales that have a pale margin. Fertile pinnules are distinctly stalked and lobed. Sori occur in four pairs per pinnule lobe and lack indusia.
Leptomys is a genus of rodent endemic to New Guinea. It is considered part of the New Guinea Old Endemics, meaning it was part of the first wave of murine rodents to colonize the island. Leptomys are seen to have minimal adaptations to their aquatic life style. Elongated hind feet accompanied by elongated centre toes suggest the ability to leap. The third molar which is lost is many rodents is retained but smaller in size. Small eyes and ears can be seen amongst its velvety soft fur.
Paraleptomys is a genus of rodent from New Guinea. It is considered part of the New Guinea Old Endemics, meaning it was part of the first wave of murine rodents to colonize the island. Members of the genus are similar to those in Leptomys but differ in that they do not have elongated hind feet or a third molar. Little is known of the two species' biology.
Alsophila arfakensis, synonym Cyathea kanehirae, is a species of tree fern native to western New Guinea, where it grows in montane forest at an altitude of 1600–2700 m. The trunk of this plant is erect and 1–4 m tall. Fronds may be bi- or tripinnate and 1–2 m in length. The rachis is smooth, while the stipe is dark and warty. The stipe is covered with flat, brown, scattered scales. Sori are borne near the fertile pinnule midvein. They are protected by small indusia that are cup-like in appearance.
Hylomyscus is a genus of rodent in the family Muridae endemic to Africa.
The long-footed water rat is a species of rodent in the family Muridae. It is found in the mountains of southern Papua New Guinea. Its natural habitat is subtropical or tropical dry forest.
Ernst Mayr's water rat is a species of rodent in the family Muridae, named for evolutionary biologist Ernst Mayr. It is found in the Foja Mountains of Papua Province, Indonesia, and in the mountains of northeastern Papua New Guinea.
The Fly River water rat is a species of rodent in the family Muridae. It is found only in Papua New Guinea. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.
Myristica arfakensis is a species of plant in the family Myristicaceae. It is endemic to West Papua (Indonesia).
German's one-toothed moss mouse is a species of rodent in the family Muridae which occurs in the mountains of southeastern New Guinea.
The Central Range montane rain forests is a tropical moist forest ecoregion on the island of New Guinea. The ecoregion covers the Central Range of the New Guinea Highlands, which extends along the spine of the island. The montane rain forests of the ecoregion are distinct from the surrounding lowland forests, and are home to many endemic plants and animals.
The New Ireland forest rat is a large rodent in the family Muridae. It is endemic to New Ireland, in the Bismarck Archipelago, Papua New Guinea.
Leptomys paulus is a small rodent belonging to the family Muridae endemic to New Guinea.
Praomys coetzeei is a species of mouse in the family Muridae.
