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.
There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the "world's largest pharmacy", because over one quarter of natural medicines have been discovered there. [2]
Rainforests are home to half of all the living animal and plant species on the planet and roughly two-thirds of all flowering plants can be found in rainforests. [ 7 ] [ 8 ] The most representative are the Borneo rainforest, one of the oldest rainforests in the world, the Brazilian and Venezuelan Amazon Rainforest , as well as the eastern Costa ...
The Wet Tropics rainforests are a biodiversity hotspot and recognised internationally for their ancient ancestry and many unique plants and animals. The area covers 0.1% of the Australian landmass but contains 50 per cent of all the nation's species. [5] Many plant and animal species in the Wet Tropics are found nowhere else in the world.
The unique ecosystem found in the intricate mesh of mangrove roots offers a quiet marine habitat for young organisms. [30] In areas where roots are permanently submerged, the organisms they host include algae , barnacles , oysters , sponges , and bryozoa , which all require a hard surface for anchoring while they filter-feed.
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 remaining rain forest contains a great number of unique plant species. The country has some 900 species of orchid. Bananas, mangoes, coconut, vanilla, and other tropical plants grow on the coasts, and the eucalyptus tree, brought from Australia, is widespread today. Wood and charcoal from the forests are used to meet 80% of domestic fuel needs.
The south Florida pine rockland is unique geographically. Southern Florida is located at the southern end of the temperate North American Floristic Region and at the northern end of the tropical Caribbean Floristic Region. [13] This location allows for the mixture of vegetation from two distinct areas at the extremes of their ranges. [14 ...
