Average Of 35 Species Of Rainforest Animals example essay topic

In this term paper, I will explain the great importance of the tropical Rainforests around the world and discuss the effects of the tragedy of rainforest destruction and the effect that it is having on the earth. I will write on some specific plants and animals that call the tropical rain forests their home; there are many different types of rainforest species and their uniqueness from the rest of the world is amazing. I will also touch on the efforts being made to help curb the rate of rainforest destruction and the peoples of the rainforest. Rain forests are located near the equator in the tropics and are most noted for their abundance of vegetation and extreme diversity. Classified by climate and location, all rain forests are dominated by various sized trees so clustered that different layers have developed in the depths of the jungles. The upper canopy, containing the tallest trees ranging from 100-150 feet, receives the most light.

Beneath the upper canopy are 1-3 layers of vegetation called the canopy. Here the plants are so condensed that so little light reaches past it, no allowing the final layer, the understory, to have a nice amount of sunlight. Only a handful of rays it the floor, causing little vegetation to grow. Due to climate and location, mother nature has created several rain forest classified differently due to unsimillar characteristics. The Equatorial rain forest is located in warm, we areas with low altitude, near the equator. Under primary influence of moisture, an average annual rainfall of 125 inches and constant temperatures of about 87 degrees together make such a diverse and fragile ecosystem (Encarta).

Tropical rain forests extended 10 degrees latitude from the equator are called subtropical rainforests. Most commonly found in Central America, West Indies and coastal Brazil, the changes in temperature and season switches give a less diverse forest compared to the Equatorial rain forests (Encarta) Some rainforests shouldnt be called rainforests at all. Found at low elevations and even farther away from the equator, the Monsoon rain forest barely gets any precipitation, 51 inches annually. Drought ed by a 4-5 month dry season, pant life is limited.

With a more open canopy, a dense under growth has grown on the forest floor. Because of the dry season and little rain fall, there is a high flammability rate. Tropical Rainforests are home to many of the strangest looking and most beautiful, largest and smallest, most dangerous and least frightening, loudest and quietest animals on earth. There are many types of animals that make their homes in the rainforest some of them include: jaguars, toucans, parrots, gorillas, and tarantulas. Dont be surprised if you see an antelope the size of a rabbit either (Rain forest Action Network). In the rain forest, all species of plants and animals work together to create and maintain such diversity.

There are so many fascinating animals in tropical rainforest that millions have not even identified yet. In fact, about half of the worlds species have not even been identified yet. But sadly, an average of 35 species of rainforest animals are becoming extinct every day (rain-tree. com). So many species of animals live in the rainforest than any other parts of the world because rainforests are believed to be the oldest ecosystem on earth. Some forests in southeast Asia have been around for at least 100 million years, ever since the dinosaurs have roamed the earth. During the ice ages, which occurred about 10,000 years ago, the frozen areas of the North and South Poles covered much of the earth, causing huge numbers of extinctions, but the great freeze did not reach many tropical rainforests.

Therefore, these plants and animals could continue to evolve, developing into the most diverse and complex ecosystems on earth. The nearly perfect conditions for life also help contribute to the great number of species. With temperatures constant at about 75-80 degrees Fahrenheit the whole year, the animals dont have to worry about freezing during the cold winters or finding hot shade in the summers (Encarta). They rarely have to search for water, because rain falls almost every day in tropical rainforests. Some rainforest species have populations that number in the millions.

Other species consist of only a few dozen individuals. Living in limited areas, most of these species are found nowhere else on earth. For example, the makes marmoset, a species of monkey, wasnt discovered until recently. Its entire tiny population lives within a few square miles in the Amazon rainforest. This species of monkey is so small that it could fit into a persons hand!

(Rain Forest Action Network) In a rainforest, it is difficult to see many things other than the millions of insects creeping and crawling around in every layer of the forest. Scientists estimate that there are more than 50 million different species of invertebrates living in rainforests. A biologist researching the rainforest found 50 different species of ant on a single tree in Peru! A few hours of crawling in a rainforest would produce several insects unknown to science. The same scientist, Al Gentry, also counting tree and liana species, observed an extravagant 2.5 acres in the Amazon basin rain forest with an amazing 283 species of trees, larger than 4 inches in diameter. In the same plot, Gentry counted a whopping 580 trees between those characterized above.

Globally, all rain forests, no matter how low quality contain an average of 185 species of trees in 2.5 acres (Emmons, p 2). Compared to the richest woodland areas of the United States, there are only about 20 species of trees with the same qualities. However, most temperate forests are much poorer than this (Emmons, p 2). The constant search for food, water, sunlight and space is a 24-hour pushing and shoving match. With this fierce competition, it is amazing that that so many species of animals can all live together. But this is actually the cause of the huge number of the different species.

The main secret lies in the ability of many animals to adapt to eating a specific plant or animal, which few other species are able to eat. An example of such adaptations would be the big beaks of the toucans and parrots. Their beaks give them a great advantage over other birds with smaller beaks. The fruits and nuts from many trees have evolved with a tough shell to protect them from predators. In turn toucans and parrots developed large, strong beaks, which serves as a nutcracker and provides them with many tasty meals. Many animal species have developed relationships with each other that benefit both species.

Birds and mammal species love to eat the tasty fruits provided by trees. Even fish living in the Amazon River rely on the fruits dropped from forest trees. Then, the fruit trees depend upon these animals to eat their fruit, which helps them to spread their seeds to far - off parts of the forest. In some cases both species are so dependent upon each other that if one becomes extinct, the other will as well.

This nearly happened with trees that relied on the now extinct dodo birds. They once roamed Mauritius, a tropical island located in the Indian Ocean. They became extinct during the late 19th century when humans over hunted them. The calvaria tree stopped sprouting seeds soon after. Scientists finally concluded that, for the seeds of the calvaria tree to sprout, they needed to be digested by the dodo bird.

By force feeding the seeds to a domestic turkey, who digested the seeds the same way as the dodo bird, the trees were saved. Unfortunately, humans will not be able to save each species in this same way. Each species has evolved with its own set of unique adaptations, ways of helping them to survive. Every animal has the ability to protect itself from being someones next meal. To prevent the extinction of a species each and every species must develop a defense tactic.

The following are just a few of Mother Natures tricks: The coloring of some animals acts as protection from their predators. Insects play some of the best hide-and-go-seek in the forest. The walking stick is one such insect; it blends in so well with the palm tree it calls its home that no one would notice unless its moved. Some butterflies, when they close their wings, look exactly like leaves. Camouflage can however help predators, such as boa constrictors, sneak up on unsuspecting animals and surprise them. The tree-toed sloth is born with brown fur, but you would never know this by looking at it.

The green algae that makes its home in the sloths fur helps it to blend in with the tops of the trees, the canopy, where it makes its home. But even green algae isn't the only thing living in a sloths fur; it is literally bugged with a variety of insects. 978 beetles were once found living on one sloth. The sloth has other clever adaptations. Known for its snail-like pace, it is one of the slowest moving animals on earth.

It is so slow that it often takes up to a month to digest its food. Being make a good meal for jaguars and other predators, most do not notice the sloth as it hangs in the trees, high up in the canopy (Encyclopedia Britannica). Other animals dont want to let their presence to the whole forest. Armed with dangerous poisons used in life threatening situations, their bright colors warn predators to stay away. This allows them to survive everyday emergency situations. The coral snake of the Amazon, with its brilliant red, yellow, and black coloring, is recognized as one of the most beautiful snakes in the world, but it is just as deadly as it is beautiful.

The coral snakes deadly poison can kill in seconds. Other animals know to stay away from it. The poison arrow frog also stands out with its brightly colored skin. It's skin produces some of the strongest natural poison in the world, which indigenous people often use for hunting purposes. It's poison is now being tested for use in modern medicine.

In a single rainforest habitat, several species of squires can live together without harming one another. Why can nine species of squirrels live together Well, in a brief summary each of the nine species is a different size; three have specialized diets or habitats, which leaves six species that feed on nuts, fruits and insects, and so potentially compete for food. A closer look showed that three of the six, a large, a medium, and a small one live in the forest canopy and never come to the ground. The largest squirrel feeds mainly on very large, hard nuts, and the smaller ones eat smaller fruits and nuts. The other three species, again a large medium and small one live in the ground and eat fruits and nuts of the same species as their canopy neighbors, but only after they fall to the ground. Tropical rainforests are bursting with life.

Not only do millions of species of plants and animals live in rainforests, but many people also call the rainforest their home. In fact, Indigenous, or native, people have lived in rainforests for thousands of years. In North and South America they were mistakenly named Indians by Christopher Columbus, who thought that he had landed in Indonesia, then called the East Indies. The native people of the rainforest live very different lives than us. In this section, I will explain how very different our lives differ than from the indigenous people of the rainforest.

Although many indigenous people live very much like we do, some still live as their ancestors did many years before them. These groups organize their daily lives differently than our culture. Everything they need to survive, from food to medicines to clothing, comes from the forest: FOOD Besides haunting, gathering wild fruits and nuts and fishing, Indigenous people also plant small gardens for other sources of food, using a sustainable farming method called shifting cultivating. First they clear a small area of land and burn it. Then they plant many types of plants, to be used for food and medicines. After a few years, the soil has become too poor to allow for more crops to grow and weeds to start to take over.

So they then move to a nearby uncleared area. This land is traditionally allowed to regrow 10-50 years before it is farmed again. Shifting cultivation is still practiced by those tribes who have access to a large amount of land. However, with the growing number of non-Indigenous farmers and the shrinking rainforest, other tribes, especially in Indonesia and Africa, are now forced to remain in one area. The land becomes a wasteland after a few years of overuse, and cannot be used for future agriculture.

EDUCATION Most tribal children dont go to schools like ours. Instead, they learn about the forest around them from their parents and other people in the tribe. They are taught how to survive in the forest. They learn how to hunt and fish, and which plants are useful as medicines or food. Some of these children know more about rainforests than scientists who have studied rainforests for many years. The group of societies known as Europeans includes such cultures such as Spanish and German.

Similarly, the broad group, Indigenous peoples includes many distinct culture groups, each with its own traditions. For instance, plantains (a type of banana) are a major food source for the Yanomami from the Amazon while the Pen an of Borneo, Southeast Asia, depend on the sago palm (a type of palm tree) for food and other uses. All Indigenous people share their strong ties to the land. Because the rainforest is so important for their culture, they want to take care of it.

They want to live what is called a sustainable existence, meaning they use the land without doing harm to the plants and animals that also call the rainforest their home. As a wise Indigenous man once said, The earth is our historian, our educator, the provider of food, medicine, clothing and protection. She is the mother of our races. Indigenous peoples have been losing their lives and the land they live on ever since Europeans began colonizing 500 years ago.

Most of them died from common European diseases which made Indigenous people very sick because they had never had these diseases before. A disease such as the flu could possibly kill an indigenous person because he / she has not been exposed to this disease before. Many Indigenous groups have also been killed by settlers wanting their land, or put to work as slaves to harvest the resources of the forest. Others were converts to Christianity by missionaries, who forced them to live like Europeans and give up their cultural traditions. Since we (the US and other countries) have been working with the Indigenous People and other rainforest protection agencies, we have learned many things about the forest, including its ecology, medicinal plants, food and other products.

It has also showed us how crucial it is for the Indigenous people of the rainforest to continue their daily and traditional activities because of their importance in the cycle if the rainforest (congo-online. com). One Indigenous man is leading the fight to preserve is home in the Amazon rainforest. Medicine man Davi Kopen awa Yanomami cures his brothers with the power and spirit provided to him by a giant anaconda spirit that lives in the Amazon basin. Using hallucinogenic powders to contact the spirit world, Davi, leader of the Yanomami Indians, is taking a modern approach to his quest. Davi is a prophet that sees his people, land and rain forest gods being swept towards exticntion. After tense pressure from Davi and friends, the Brazillian government set aside 36,000 square miles for the Yanomami homeland (McG irk, 83).

Scientists have come to the conclusion the rain forests are potentially more valuable on a long-term basis. If left intact, an even larger standing biomass can be created. Todays biodiversity of the rain forest has been conditioned independent of soil conditions by recycled nutrients. Rain forests properly managed and cared for are able to provide mass amounts of quality timber and stablalize the local climate, as well as many other beneficial good things. Medicinal products already available from the rain forest include diosgenin, an ingredient in contrasepitive pills; resperine, treating cardiac problems; and curare, used in heart and lung surgery. If the rain forest is left alone and allowed to evolve, more studies needed can be conducted for future benefits in the medical field as well as consumer products.

One company, Merck, specializing in medicinal drugs, has been during its part to help rainforests through biological prospecting. Merck has local technicians collect samples to possibly uncover a new medicine. If a breakthrough is found, Costa Rica will share in the profits, also the local people will earn a living by studying the rain forest instead of destroying it (Kowalski, 2). The large number of natural disasters, cyclones, lighting fires, etc., are just a minimal effect compared to human activity.

Logging, road construction, mining, and cattle farming have led the attack on the forests (Encarta) The method of slash and burn is commonly used, where small areas of land are used. Many areas were cleared for banana and coffee growing or pasture. However, due to the lack of nutrients in the soil, its value depleted and were abandoned. The time it takes for the area to regrow is insane to even think about, because the soil needs decaying plant matter to support the lush vegetation. The destruction of rainforests affects pollination patterns, migration routes, and food chain links (Kowalski, 32). If human impact is affecting these forest like this now, who knows what may happen to these brilliant ecosystems.
