The jaguar lives in a tropical rain forest biome.

The average temperature in a tropical rain-forest is 25 - 30 degrees.

The average monthly precipitation in a tropical rain-forest is about 160cm.


Physical Geography/ Features
The tropical rainforest biome is located in multiple regions around the world. All of them are located near the equator. This placement means that this biome is very hot and humid year - round, with a very constant temperature. In Manaus, the capital city of Amazonas, Brazil, the average temperature is 30 degrees celsius year-round. The Amazon contains more than half of the world's rainforests. These forests are home to hundreds of species. 1/3rd of the world's species, to be more precise. The tropical rainforest biome has great biodiversity. Even though this area is considered a tropical rainforest, it is also known as a monsoon climate, for its heavy rainfall year-round. The air in the Amazon forest is very humid, because of the hot, wet climate. The soil in the Amazon is extremely fertile because of the lush vegetation and wide range of species. Because of this humid climate, plants grow plentifully, making the oxygen very rich. The tropical rainforest biome is located near the South Pacific Ocean, the South Atlantic Ocean, and North Pacific Ocean.

Adaptations of Organisms
The Jaguar's rear legs are longer than the front legs to help it jump. This feature helps it to catch prey and jump higher. The jaguar also has loose belly skin so if it is ever kicked by an animal, there is less of a chance of injury. Its long, sharp claws make it easy for it to catch and kill prey, and climb trees. Some more of the jaguar's structural adaptations are their large head, which is used, ironically, to bite and crush the skulls of it's prey. This adaptation may also fall under behavioural, as most cats kill prey with a bite to the neck. The jaguar is also equipped with large spots all over its body, which increases its camouflage. Lastly, the jaguar is an exceptional swimmer, which comes in handy in the wet climate.

Some trees in the tropical rainforest grow smooth bark that helps limit the loss of moisture, making it more difficult for animals to climb the tree. This is a structural adaptation.

Squirrel monkeys have long tails to help them grab onto branches and balance. This is a structural adaptation.

Symbiosis with the Jaguar:

A symbiotic relationship that the jaguar has is with the entire jungle. It is a keystone predator, with a diet of up to 87 species. The jaguar keeps down the population of the other species in the forest by being the top predator. It has a Mutualism relationship with the tropical rainforest. The jaguar feeds, and the tropical rainforests's population is kept normal.


Human Impact on the Tropical Rainforest
Humans have had a major impact on the tropical rainforest. Originally, 14% of the earth was covered in lush, green rainforest. Today, a chunk approximately the size of a football field is cut down each second. Humans are the most invasive species known to the rainforest. Before we were introduced to this environment, the rainforest lived peacefully, and in balance. Humans began to deforest, clear-cutting hectare after hectare of rainforest, all for the beautiful natural resources it contains. Since then, many species have become endangered or extinct.

The jaguar's role in the tropical rainforests of Brazil is extremely important. The jaguar is a keystone species. This means that if the jaguar was ever to become extinct, the tropical rainforest would be off-balance and the ecosystem would begin to fail. The jaguar has become endangered because of the over-exploitation of the resources that come from the tropical rainforest, such as valuable wood, and usable land. Illegal logging takes place across the Amazon. This must stop. Clear cutting has reduced the rainforest by more than half of its original size. With the smaller amount of untouched luscious forest for the jaguar to roam in, it will have a harder time finding prey to feed on, and land to call home. This can and will lead to the extinction of the jaguar.

To stop this imminent threat, we must learn to not be so greedy, for that is what has caused this catastrophe. We must improve laws and reinforcement on illegal and commercial clear-cutting, and stop burning of the tropical rainforest. If we want to save this beautiful biome, we must counter-attack our actions.

Learning Outcomes
As a result of creating this project, I have become familiar with different biomes, how species interact within biomes, and creating climatographs. I have also become more familiar with the factors that influence a biome, and how to predict a biome.

In addition, I have learned how to use wikispaces more in-depth. I learned about adaptations of my organism, and others.
