A tropical rainforest is a luxuriant forest found in wet tropical uplands and lowlands near the Equator. Tropical rainforests are dominated by broad-leaved trees that form a dense upper canopy and contain a wide array of vegetation and other life.
Tropical rainforest - Biodiversity, Climate, Ecosystem: The equatorial latitude of tropical rainforests and tropical deciduous forests keeps day length and mean temperature fairly constant throughout the year. The sun rises daily to a near-vertical position at noon, ensuring a high level of incoming radiant energy at all seasons.
Tropical rainforests are found primarily in South and Central America, West and Central Africa, Indonesia, parts of Southeast Asia, and tropical Australia. The climate in these regions is one of relatively high humidity with no marked seasonal variation.
Tropical rainforest - Biodiversity, Ecosystems, Canopy: Tropical rainforests are distinguished not only by a remarkable richness of biota but also by the complexity of the interrelationships of all the plant and animal inhabitants that have been evolving together throughout many millions of years.
Amazon Rainforest, large tropical rainforest occupying the Amazon basin in northern South America and covering an area of 2,300,000 square miles (6,000,000 square km). It is the world’s richest and most-varied biological reservoir, containing several million species.
For example, a study of insects in the canopy of four different types of tropical rainforest in Brazil revealed 1,080 species of beetle, of which 83 percent were found in only one forest type, 14 percent in two, and only 3 percent in three or four types.
temperate rainforest, in ecology, a biome dominated by a mix of broad-leaved or coniferous trees that occurs in the middle latitudes, mostly between approximately 40° and 60° in both Northern and Southern hemispheres, and characterized by abundant moisture present throughout the year.
Tropical rainforest - Flora, Fauna, Relationships: Some of the tallest trees and lianas, and the epiphytes they support, bear flowers and fruits at the top of the rainforest canopy, where the air moves unfettered by vegetation. They are able to depend on the wind for dispersal of pollen from flower to flower, as well as for the spreading of ...
tropical dry forest, biome of any open woodland in tropical areas that have a long dry season followed by a season of heavy rainfall. Tropical dry forests are found between 10° and 25° latitude and are often found north and south of the world’s tropical rainforests.
Tropical rainforests occur around the equator in the hot, wet region called the tropics. They are found in parts of the tropics that get more than 70 inches (180 centimeters) of rain each year. Parts of South America and Central America, western and central Africa, Southeast Asia, and Australia have tropical rainforests.
