Some tropical areas may receive abundant rain the whole year round, but others have long dry seasons which last several months and may vary in length and intensity with geographic location. These seasonal droughts have a great impact on the vegetation, such as in the Madagascar spiny forests. [1] Rainforest vegetation is categorized by five ...
An area of the Amazon rainforest in Brazil. The tropical rainforests of South America contain the largest diversity of species on Earth. [1] [2] Tropical rainforest climate zones (Af). Tropical forests: from the UN FRA2000 report. Tropical rainforests are dense and warm rainforests with high rainfall typically found between 10° north and south ...
Despite the growth of vegetation in a tropical rainforest, soil quality is often quite poor. Rapid bacterial decay prevents the accumulation of humus. The concentration of iron and aluminium oxides by the laterization process gives the oxisols a bright red colour and sometimes produces mineral deposits such as bauxite. Most trees have roots ...
The Amazon rainforest, [a] also called Amazon jungle or Amazonia, is a moist broadleaf tropical rainforest in the Amazon biome that covers most of the Amazon basin of South America. This basin encompasses 7,000,000 km 2 (2,700,000 sq mi), [ 2 ] of which 6,000,000 km 2 (2,300,000 sq mi) are covered by the rainforest . [ 3 ]
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 ...
The Hawaiian tropical rainforests are a tropical moist broadleaf forest ecoregion in the Hawaiian Islands. They cover an area of 6,700 km 2 (2,600 sq mi) in the windward lowlands and montane regions of the islands. [1] Coastal mesic forests are found at elevations from sea level to 300 m (980 ft). [2]
In tropical lowland forest environments, a minimum of 22 species from eight different families are known to create monodominant forests. [1] Examples of persistent monodominance are seen in Africa, Central and South America, and Asia. [5] Dipterocarpaceae is one example of a plant family that is recognized as persistently dominant in Asia. [5]
The Borneo lowland rain forests is an ecoregion, within the tropical and subtropical moist broadleaf forests biome, of the large island of Borneo in Southeast Asia. [1] It supports approximately 15,000 plant species, 380 bird species and several mammal species.
