A surplus of rain and high insolation sunlight are other year-round attributes of a tropical rainforest. Tropical rainforests cover the site region, as well as equatorial regions in Africa, Southeast Asia, the east coast of Central America and elsewhere along the equator. These types of forest ecosystem are characterized by broadleaf evergreen trees, vines, tree ferns and palms.
Many tropical rainforests are known for their incredible biodiversity. Jungles like the site are home to thousands of different types of species. Those include animals that crawl along the ground, like insects, lizards and rodents, as well as those that swing through the trees, like monkeys.
Tropical rainforests also house vicious predators like anacondas and jaguars. Located on the edges of rainforests are the tropical seasonal forests that receive dwindling and irregular rainfall. Some of the key parts of a forest in this zone are broadleaf evergreen trees, some deciduous trees and thorn trees.
Structure and Functioning of Forest Ecosystems
Deciduous trees lose their leaves during the winter. Found in North America, Europe and Asia, temperate evergreen and deciduous forests tend to blend together at times.
Needleleaf and broadleaf trees inhabit the forests. In southern and eastern areas that are fervent with evergreen pines, controlled forest fires still take place as the natural cycle of forest re-growth and enrichment.
They are called temperate forests because of their weather conditions. Compared to the extreme heat and humidity of a tropical rainforest, temperate evergreen and deciduous forests have moderate climates, with pleasantly warm summers and bearably chilly winters.
The boreal forest, also known as the needleleaf forest, covers most of the subarctic climate areas located in Canada, Alaska, Siberia, Russia and Europe. While there aren't any boreal forests in the southern hemisphere, there are mountain forests comprised of needleleaf trees that survive all over the world at extremely high elevations.
Boreal forests are home to many of the plants and animals typically thought of as forest-dwellers, such as foxes, moose, reindeer, bears, squirrels and wolves. Plants like fungi, mosses and lichen do well in the boreal climate, because they are tough enough to survive what can often be extremely cold, icy winters. Savanna and woodland ecosystems have a susceptibility to fires and the ability to rejuvenate and re-grow.
Prevalent in South America, Africa and Australia, savannas and woodlands are characterized by vast areas of grasslands, bush thickets and clusters of sparse trees with flattened crowns.These materials are decomposed by worms, microbes, fungi, ants, and other bugs. Plants produce their own food, in the form of carbohydrates.
Deciduous trees lose their leaves during the winter. While there aren't any boreal forests in the southern hemisphere, there are mountain forests comprised of needleleaf trees that survive all over the world at extremely high elevations. When humans remove trees, this opens the overstory to suppressed trees, leading to quick changes in structure and function.
