There are 138 species of mammals in the ecoregion, mostly marsupials, bats, and murid rodents.Seven mammal species are endemic: broad-striped dasyure (Paramurexia rothschildi), giant bandicoot (Peroryctes broadbenti), Papuan bandicoot (Microperoryctes papuensis), New Guinea big-eared bat (Pharotis imogene), Chiruromys lamia, Long-nosed mosaic-tailed rat (Melomys levipes), and Van Deusen's rat ...
The Northern New Guinea montane rain forests is a tropical moist forest ecoregion in northern New Guinea. The ecoregion covers several separate mountain ranges lying north of New Guinea's Central Range and south of the Pacific Ocean. [2] [3] [4]
The ecoregion includes the foothills and lowlands south of New Guinea's Central Range. Above 1000 meters elevation, the lowland forests transition to the Central Range montane rain forests . The Southern New Guinea freshwater swamp forests ecoregion covers extensive areas of the Fly River lowlands to the south, and the lower reaches of some ...
New Guinea is in the Australasian realm, which also includes the islands of Wallacea to the west, the Bismarck Archipelago, Solomon Islands, and Vanuatu to the east, and Australia and New Zealand. [1] Sea levels were lower during the Ice Ages, which exposed the shallow continental shelf and connected New Guinea to Australia into a single land mass.
Lowland evergreen rain forest is the most extensive, and includes alluvial forests in the plains, and hill forests in the foothills of the adjacent mountains. [ citation needed ] There are extensive freshwater swamp forests in the coastal lowlands and in the Lakes Plains region between the Van Rees-Foja mountains and the Central Range.
A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
In order to more efficiently show the quantity of organisms at each trophic level, these food chains are then organized into trophic pyramids. [1] The arrows in the food chain show that the energy flow is unidirectional, with the head of an arrow indicating the direction of energy flow; energy is lost as heat at each step along the way.

Papua New Guinea is largely mountainous, and much of it is covered with tropical rainforest. The New Guinea Highlands (or Central Range) run the length of New Guinea, and the highest areas receive snowfall—a rarity in the tropics. Within Papua New Guinea Mount Wilhelm is the highest peak, at 4,509 m
