Borneo rainforest. Some tropical forest types are difficult to categorize. While forests in temperate areas are readily categorized on the basis of tree canopy density, such schemes do not work well in tropical forests. [1] There is no single scheme that defines what a forest is, in tropical regions or elsewhere.
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 with a warm summer wet season and (often) a cooler winter dry season. Some trees in these forests drop some or all of ...
Amazon River rain forest in Peru. Tropical rainforests are hot and wet. Mean monthly temperatures exceed 18 °C (64 °F) during all months of the year. [4] Average annual rainfall is no less than 1,680 mm (66 in) and can exceed 10 m (390 in) although it typically lies between 1,750 mm (69 in) and 3,000 mm (120 in). [5]
Biogeography is related to the physical conditions and geography of the habitat. The temperature and geographical area of the tropics enforce the latitudinal species gradients by facilitating higher rates of speciation. Tropical biomes are defined as warm, moist habitats, and cover the largest amount of the terrestrial area on earth.
The tropical and subtropical grasslands, savannas, and shrublands are characterized by rainfall levels between 90–150 centimetres (35–59 in) per year. [1] Rainfall can be highly seasonal, with the entire year's rainfall sometimes occurring within a couple of weeks. African savannas occur between forest or woodland regions and grassland regions.
The Central Polynesian tropical moist forests is a tropical and subtropical moist broadleaf forests ecoregion in Polynesia. It includes the northern group of the Cook Islands , the Line Islands in Kiribati , and Johnston Atoll , Jarvis Island , Palmyra Atoll , and Kingman Reef which are possessions of the United States.
The terms "tropical forest" and "rainforest" have largely replaced "jungle" as the descriptor of humid tropical forests, a linguistic transition that has occurred since the 1970s. "Rainforest" itself did not appear in English dictionaries prior to the 1970s. [ 22 ]
The only forest birds are the Pacific imperial pigeon (Ducula pacifica), a year-round resident, and the migratory Pacific long-tailed cuckoo (Urodynamis taitensis), which winters in the tropical Pacific and breeds in New Zealand during the spring and summer. There are no native non-marine mammals or amphibians.
