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 ...
This is a list of plants found in the wild in Amazon Rainforest vegetation of Brazil. The estimates from useful plants suggested that there are 800 plant species of economic or social value in this forest, according to Giacometti (1990). [1]
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 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]
An example is the role of fiddler crabs and their carapace-associated microbial biofilm as hotspots of microbial nitrogen transformations and sources of nitrogen within the mangrove ecosystem. [ 42 ] Among coastal ecosystems, mangrove forests are of great importance as they account for three quarters of the tropical coastline and provide ...
Australian Tropical Rainforest Plants, also known as RFK, is an identification key giving details—including images, taxonomy, descriptions, range, habitat, and other information—of almost all species of flowering plants (i.e. trees, shrubs, vines, forbs, grasses and sedges, epiphytes, palms and pandans) found in tropical rainforests of Australia, with the exception of most orchids which ...
