Tropical Rainforest
What are Tropical Rainforest ?
A Tropical Rainforest is an ecosystem type that occurs roughly within the latitudes 28 degrees north or south of the equator (in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn). This ecosystem experiences high average temperatures and a big amount of rainfall. They are also warm and wet .
Where are the Topical Rainforests ?
They are located at South and Central America , Africa and Oceania ( which are islands around Australia ) and Asia .
They are also located at Amazon River Basin (South America), the Congo River Basin (western Africa), and Centra America , Madagascar .
Madagascar
Animal species
Aye-aye
This nocturnal lemur lives in the rainforests of Madagascar and feeds on insect larvae that it finds by tapping on tree bark with its stick-like middle finger. As it taps, the aye-aye listens for movement indicative of insects and gnaws away at the wood when it hears something appetizing.

Bamboo lemur

Bamboo lemurs
feed on bamboo and are generally found in the rainforests and cloud forests of Madagascar (two species are found outside these areas).

Lepilemur, Sportive or Weasel lemur

Lepilemurs are nocturnal lemurs that are easily spotted during daylight hours as they rest in tree hollows. Lepilemurs, which are neither weasel-like nor sportive, feed on leaves and are quite vocal at night.

Tropical Rainforest
There are three layers , the emergent which reaches a height of 40 or 50 meters (about 14 to 16 storeys high) . Trees often have buttress roots to support their tall , heavy trunks .
Canopy
Tall trees reach a height of 15 to 30 meters here ( about 5 to 10 storeys high ) . Crowns of trees interlock to form a continuos leaf cover ( or canopy ) .
Undergrowth
The undergrowth is made up of shrubs , grasses , ferns , mosses and fungi .

The latitudes and climate where the Rainforests are found .

Tropical Rainforest are located in a band around the equator ( zero degrees latitude ) , mostly in the area between the Tropic of Cancer ( 23.5 degrees N latitude ) and the Tropic of Capricorn ( 23.5 degrees S latitude ) .
There are three major climatic parameters: temperature, rainfall, and dry season intensity .
It is 592,800 square kilometres (228,900 sq mi) and The country lies mostly between latitudes 12°S and 26°S, and longitudes 43°E and 51°E. There are Baobabs , Travelers Palm , Alluaudia spiny plant and more ... The Baobabs are 5 to 30 m (16 to 98 ft) and have trunk diameters of 7 to 11 m (23 to 36 ft) . The tree provides a source of fiber, dye, and fuel. Indigenous Australians used baobabs as a source of water and food, leaves for traditional medicine, and painted or carved fruits to be worn as ornaments. Travelers Palm are enormous paddle-shaped leaves that are borne on long petioles, in a distinctive fan shape aligned in a single plane. Alluaudia spiny plant are spiny succulent shrubs and trees from 2–20 m tall, with leaves that are deciduous in the long dry season. The leaves are in pairs, 0.5-3.5 cm long, with one or two thorns 2-2.5 cm long in the axil of each pair of leaves. The flowers are small, grouped many together in large numbers .
