THE BORNEO RAINFOREST
The tropical rainforest is earth's most complex biome in terms of both structure and species diversity. Tropical Rainforests can be found in South and Central America, Africa, Oceania (the islands around Australia), and Asia (15).Tropical rainforests cover only about 7% of the Earth's surface (13, )All Tropical Rainforests have similar characteristics including climate, precipitation, etc. They are located in a band around the equator. However, not every tropical rainforest can claim exact characteristics when compared by region. Many may blend with adjoining mangrove forests, moist forests, mountain forests, or tropical deciduous forests (13). Sunlight is

Usually, they call only when they defend their territories from other breeding pairs (12). Hornbills are critical to the dispersal of the figs because they eat the entire fruit, including the seed, and then fly long distances dispersing the seeds widely (11). They spend their entire lives on treetops. To nest, however they look for old or dead trees with cavity. When the female is ready to lay her eggs, she uses food and droppings to seal the entrance (10). The female incubates the egg in the cavity for the next 50 days. She keeps the nest clean by throwing out uneaten food and the poop. The male bird brings food for the female and chicks (11). Three months or 100 days after the chicks hatch, the female bird breaks out of the nest. The chicks then rebuild the covering and receive food from their parents for the next three months (12).When the chicks grow; they break the nesting hole and fly free.
The Rafflesia flower is one of the rarest and most astonishing flowers in the world, including the very largest, is found only in Borneo and Sumatra. It weighs up to 10kg (4). The Rafflesia flower starts as a small bud and can take over a year to flower. Rafflesia plants are parasitic, lacking both leaves and roots; it drains nourishment and gains physical support from its host vine (4). Its only body outside the flower consists of strands of fungus-like tissue that grow inside the Tetrastigma vine. The flower is not designed
Tropical rainforests are extremely humid because of the rainfall. Majority of rainforests receive an approximate 250cm of rain per year. Rainforests typically have rivers and streams and with the intense heat evaporation happens and the water cycle commences. This climate is found closer to the equator. Nearly 50% of all tropical rainforests are found in Latin America while one third is located in Brazil. Other Tropical rainforests are located in Southeast Asia and the Pacific islands with an estimated (25% of worlds rainforests) while west of Africa only has 18%.
As a result of deforestation and other causes, as few as 10,000 species go extinct every year, with a multitude lost in the rainforests across the world. The Amazon Rainforest, the largest rainforest in the world, houses roughly, “40,000 plant species, 427 mammals, 1,300 birds, 378 reptiles, and around 3,000 freshwater fish,” as well as more than 100,000 of invertebrate species (Amazon Wildlife). The rapid loss of the Amazon rainforest, precisely 17% in the last fifty years, critically cripples the biodiversity of the rainforest. To explain, every vehicle that destroys any sort of foliage is a loss to the animals that live in the forest. As known, every animal consumes a multitude of different plants or animals, and the more plants in the area,
The Interdependence of plants, animals, and humans is integral in the Amazon Rainforest ecosystem of the tropical rainforest biome. The key features of the Amazon Rainforest is the Amazon River. The Amazon Rainforest goes through Brazil, Peru, Colombia, and many other countries. Colombia has 10%, Brazil has 60%, and Peru has 13%. 80-90 degrees during the day and 50 degrees at night is the temperature of the Amazon Rainforest. There are dry and wet seasons. it gets 9 to 10 feet of rain a year. The terrain is in the Amazon Rainforest are rocky mountains, wetlands , plains, valleys, rivers, streams, and highlands. The dirt is poor with very few nutrients and it is very muddy. It is also dense with trees and rotting logs. The thin topsoils, made of decaying vegetable and animal parts, take up all the nutrients. In the Amazon Rainforest there 's the Congo River, the Rio Negro, and the Amazon River.
My team has discovered a new population of sloths in the Amazon Rainforest. The team has a job of figuring out three things regarding these sloths. The team has to determine if the new population is evolving, how it is related to other sloth populations near it, and if it is a different species than the other sloth populations.
More than half of the world’s tropical rainforests can be found in Central and South America, however they are also present in south eastern Asia and Africa. All of the world’s tropical rainforests can be found at the approximate location of -20 degrees latitude, also known as the area between the Tropic of Cancer and the Tropic of Capricorn. These types of areas exist because of the specific climate, soil types, and diversity present in these regions. This specific area falls in the equatorial and tropical zone and are therefore their climates are controlled by the intertropical convergence zone (ITCZ) and it’s low pressure centers around the equator. Winds present are moist equatorial (mE) and moist tropical
The tropical rainforest biome is an ecosystem covering around 6% of the Earth’s surface and being a home to over 50% of the plant and animal species. These environments are hot and humid all year round, with the average amount of rainfall being 250cm per year. The temperatures in a rain forest minimum tends to be around 20OC with the temperature not rising above 34OC regularly. Tropical rainforests are found spanning from both sides of the equator between the tropic of Cancer and the tropic of Capricorn meaning rainforests are in Central and South America, Southeast Asia, Africa and Australia.
Tropical rainforests are the Earth?s oldest, richest, most productive, and most complex living ecosystems. They are located throughout many of the world?s continents including South America, Africa, and Asia and are defined by a few specific factors. Their location must be within the regions of the tropics and they must receive between 4-8 meters of rain per year (compared to about 1-2 meters in the United States). These forests also have no ?seasonality?, which means that they lack a definite dry or cold season of slowed growth.
The bird will reach its sexual maturity at the age of 2 years old. The bird is monogamous, which means it mates with a bird for many years or even life. Usually only finding new mates when one of the other mates die. Also while together the mates will defend the same nesting territory for many years. The main threat to the nesting is the Great Horn Owl. The owl begins its mating and nesting before the hawk, so this is why the hawk defends its old nesting. The hawk and owl will destroy both each other’s nests and eggs. The owls are unable to build their own nest so they try to steal the hawks. While the birds are mating they will circle around each other shrilling loud shrilling sounds. The males will then begin to do air shows going up high a diving and climbing again. He may during this briefly grab the talons of the females with his. After the air show which can last 10 minutes or longer the birds will then begin some sexual intercourse. Although there is not always the air show before reproducing. This happens usually late winter to early spring. It will happen multiple times a
Did you know that the rainforest is a fantastic biome? It has three parts that make it special. The forest is also home to more plant life than any other. It’s pretty big. Rainforests have a climate and appearance, producers, and consumers specific to the ecosystem.
To begin, climate plays a major role in the creation and maintenance of soil. Firstly, wind can blow soil to a different area. In the 1930s, there was a drought in the prairies and topsoil blew away. The soil was dry and all the vegetation died, so it was light and the wind blew the topsoil away, exposing the subsoil. This greatly reduced the amount of topsoil in the prairies. Secondly, rain supports growth of plants, creating more humus from plant decay. In the west coast forest vegetation region, there is a lot of precipitation, which supports plant growth. The large amounts of precipitation in the west coast of canada supports the plant growth. After the plants grow, they eventually die and decay, turning into humus. This fertilizes the
The Joshua tree has two ways of obtaining and saving water through its root systems, it has a shallow system that runs just beneath the ground and it has a deeper system that goes about 30 feet under the earth and is larger in
It all started when I decided to go to the rainforest to explore new animal species. My helicopter had a random malfunction and fell into into the middle of nowhere, leaving me stranded in the middle of the rainforest. My only supplies that I could find was a single flare shot, emergency food rations and some rope. My first concern is finding water. I grabbed my supplies and started heading down a trail of mud and flattened grass. After about an hour of walking the sun started to set. I noticed a large tree that had huge wide leafs. I could use these leaves and sticks to form a temporary place to sleep. I started to gather up sticks to shape sort of a tipi. Then I laid the large leaves on the top and sides, and put one inside the fort to lay
In the season spring it is rainy, hot, wet, and steamy. As you can see from the map, the tropical rainforests are indeed located in the tropics a band around the equator from 23.5 N (the Tropic of Cancer) to 23.5 S (the Tropic of Capricorn because the earth tilts 23.5 degrees on its axis as it travels around the sun at some point in the year (June 22nd in the north, December 22nd in the south) the sun will be directly overhead on one of these lines. At the equinoxes the sun is directly over the equator. Thats what makes the rainforest so
I decided to do my presentation on biomes but not just any biome, I decided on the Tropical Rainforest. The tropical rainforest biome is an ecosystem that covers 6 percent of the earth. They are found all over the earth but the majority lie in South America. Tropical rainforests are defined by their hot and wet climate. The average temperature in this area is around 75 to 80 degrees Fahrenheit. These areas often get up to 12 hours of sunlight due to being located on the Earths equator. Obviously, since it’s called a rainforest, it gets a lot of rain. Most rainforests get up to 100 inches of rain annually. Because of this warm, wet climate, the rainforest is an ideal habitat for a wide range fauna and flora. Some examples of the fauna that live
The tropical rainforest biome is located near the Tropic of Cancer and the Tropic of Capricorn, as well as along the equator.
