Rainforests can be generally classified as tropical rainforests or temperate rainforests, but other types have been described. Estimates vary from 40% to 75% of all biotic species being indigenous to the rainforests. [1] There may be many millions of species of plants, insects and microorganisms still undiscovered
The Congolian rainforests are home to over 10,000 species of plants of which 30% are endemic. [2] The Congolian rainforests are less biodiverse than the Amazon and Southeast Asian rainforests. However, its plant and animal life is still more rich and varied than most other places on Earth. The Congolian Forests are a global 200 ecoregion.
Tropical rainforests are located around and near the equator, therefore having what is called an equatorial climate characterized by three major climatic parameters: temperature, rainfall, and dry season intensity. [21] Other parameters that affect tropical rainforests are carbon dioxide concentrations, solar radiation, and nitrogen availability.
Scientists estimate that more than half of all the world's plant and animal species live in tropical rainforests. Tropical seasonal forests , also known as moist deciduous , monsoon or semi-evergreen (mixed) seasonal forests, have a monsoon or wet savannah climates (as in the Köppen climate classification ): receiving high overall rainfall ...
Beyond the northern end of Vancouver Island, is the "perhumid rain forest zone". Douglas fir wanes as a dominant species, and the forest is primarily made up of western red cedar, Sitka spruce, and western hemlock. The Gulf of Alaska begins where the fjords of southeast Alaska end, and marks the transition into "sub-polar rain forest". Here the ...
A forest ecosystem is a natural woodland unit consisting of all plants, animals, and micro-organisms (biotic components) in that area functioning together with all of the non-living physical factors of the environment. [2]
Tropical ecology is the study of the relationships between the biotic and abiotic components of the tropics, or the area of the Earth that lies between the Tropic of Cancer and the Tropic of Capricorn (23.4378° N and 23.4378° S, respectively). The tropical climate experiences hot, humid weather and rainfall year-round.
Most of the interior of the Amazon basin is covered by rainforest. [6] The dense tropical Amazon rainforest is the largest tropical rainforest in the world. [2] It covers between 5,500,000 and 6,200,000 square kilometres (2,100,000 and 2,400,000 sq mi) of the 6,700,000 to 6,900,000 square kilometres (2,600,000 to 2,700,000 sq mi) Amazon biome.
