      This website is very descriptive.could help us all out at some point

    it has some stuff about our biome

The forest biome - 1 views

  • Temperature is on average 20-25° C and varies little throughout the year: the average temperatures of the three warmest and three coldest months do not differ by more than 5 degrees. Precipitation is evenly distributed throughout the year, with annual rainfall exceeding 2000 mm. Soil is nutrient-poor and acidic. Decomposition is rapid and soils are subject to heavy leaching. Canopy in tropical forests is multilayered and continuous, allowing little light penetration. Flora is highly diverse: one square kilometer may contain as many as 100 different tree species. Trees are 25-35 m tall, with buttressed trunks and shallow roots, mostly evergreen, with large dark green leaves. Plants such as orchids, bromeliads, vines (lianas), ferns, mosses, and palms are present in tropical forests. Fauna include numerous birds, bats, small mammals, and insects.

      This could help you with the fauna aspect of the project
  • However, forests are becoming major casualties of civilization as human populations have increased over the past several thousand years, bringing deforestation, pollution, and industrial usage problems to this important biome.

  • The average temperature ranges between 27° C and 32° C but the maximum ranges between38° C and 48° C during May and June. The average rainfall is1500 mm but vary from place to place. Some regions have less then 500mm of rainfall.  Even the temporal distribution of rainfall within a single year is highly variable because more than 80% of mean annual rainfall  is received within 3 wet months of summer season.(July, August, and September).Tropical deciduous forest biome : -There is maximum evaporation during warm dry summer months due to which the foliage is dropped to conserve water and prevent death from drought. This can occur any time in the year. Even in the local areas the timings of falling of leaves varies.The number of plant species is less in tropical deciduous forest biome than the tropical evergreen rainforest biome. The height of most of the trees ranges between 12 m and 30 m. Most of the trees are deciduous ( i.e. the foliage falls at least once a year) but the shrubs are evergreen. The large leaves enable the tree to trap more and more rainfall during the wet season, but these large leaves are shed during dry periods to conserve moisture, where as the small and hard xeromorphic leaves enables the tree to withstand dry weather and water deficiencies. The tropical deciduous forest trees are Oak, American beech, chest nut hickory, elm , Sal, bamboo etc.The animals of tropical deciduous forest are elephant, American bald eagle, Black bear, Rhinos, European red squirrel etc.

  • Tropical forests lie in the areas near the equator and their climatic conditions are a combination of hot and moist conditions. The rainforests of South America, Africa, and Southeast Asia are all tropical rain forests. The precipitation level is high and evenly distributed throughout the year. This combination of hot climate and abundance of rainfall allows a large number of animals and plants to exist. The climatic condition is also suitable for the growth of many bacteria which live on the fallen leaves. Much of the nutrients released after the decomposition of the leaves are absorbed by the new plants leaving the soil less fertile
  • Being the oldest and the most complex ecosystems on earth tropical forest are a home for a large number of animals. As these forests show an abundance of a large variety of plants, the animals also dwell at different levels in the forest. For example the birds live up in the canopies and mammals live at the ground level. Due to the abundance of species of animals there is a tough competition between them. List of some animals found in this area: Bengal tigers: These are the ferocious animals of the tropical forests which can climb trees and are good swimmers. The beautiful color of their fur helps them to blend into the rainforest.
  • Gorillas: They are smart animals which can learn sign language.

  • Boa Constrictors: They are the reptiles which grow longer than 10 feet. These snakes are not poisonous and are tanned in color with dark bands. They live on small animals like bats and lizards
  • Anaconda: They are the largest snake found in marshes and swamps which feed on rodents, pigs, deer, birds, fish, etc.
  • Bengal tigers
  • Capybaras: they are the largest rodents which feed on aquatic plants, tree barks and fruits.
  • Jaguars ; they are the species of wild cats which prey on capybaras, turtles, birds and reptiles.
  • Chimpanzees: These are smart animals which can prepare hunting tools and are close relatives of human beings. They spend some time on the ground and sleep in the nests built on the trees.
  • The animals in this area show some typical adaptations like long prehensile tail of the monkeys which help them to live on the trees. Bright colors and sharp patterns, diets heavy on fruits, and loud vocalizations are other adaptations of these animals.
