Rainforest Animals - 5 views

  • Scientists believe that there is such a great diversity of animals because rainforests are the oldest ecosystem on earth.
  • Many animals 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 fruits dropped from forest trees. In turn, 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.

  • DOZENS OF ANIMAL SPECIES A DAY BECOME EXTINCT IN TROPICAL RAINFORESTS
    • Thomas C
       
      WHAT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
  • When rainforests are destroyed, animals living outside the tropics suffer as well. Songbirds, hummingbirds, warblers and thousands of other North American birds spend their winters in rainforests, returning to the same location year after year. Less return north each spring, as few make it through the winter because their habitat has been destroyed. The cutting down of trees is not the only reason for species extinction. Thousands of monkeys and other primates are traded illegally on the international market each year, wanted for their fur, as pets, or for scientific research. Parrots and macaws have also become popular pets; buyers will pay up to $10,000 for one bird. Even the king of the jungle, the jaguar, is in danger of becoming extinct. Its fur is highly valued for use on coats and shoes.

  • Scientists estimate that there are more than 50 million different species of invertebrates living in rainforests. One scientist found 50 different species of ants on a single tree in Peru! You would probably only need a few hours of poking around in a rainforest to find an insect unknown to science.
  • 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 overhunted 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 first 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 birds, the trees were saved. Unfortunately humans will not be able to save each species in this same way.

  • The constant search for food, water, sunlight and space is a 24-hour pushing and shoving match. With this fierce competition, you may be amazed that so many different species of animals can all live together. But this is actually the cause of the huge number of 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. Have you ever wondered, for instance, why toucans and parrots have such big beaks? These 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.
    • Gurupranav G
       
      This peice of information will be useful if you are looking at the adaptations of different animals in the rainforest. This is useful for me.
  • 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 someone's next meal. The following are just a few of these unique and often bizarre adaptations. CAMOUFLAGE 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 it unless it moved. Some butterflies, when they close their wings, look exactly like leaves. Camouflage also works in reverse, helping predators, such as boa constrictors, sneak up on unsuspecting animals and surprise them. SLOW AS A SNAIL The three-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 sloth's fur helps it to blend in with the tops of the trees, the canopy, where it makes its home. But green algae isn't the only thing living in a sloth's 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. Famous for its snail-like pace; it is one of the slowest-moving animals on earth. (It can even take up to a month to digest its food!) Although its tasty meat would make a good meal for jaguars and other predators, most do not notice the sloth as it hangs quietly in the trees, high up in the canopy. DEADLY CREATURES Other animals want to announce their presence to the whole forest. Armed with dangerous poisons used in life-threatening situations, their bright colors warn predators to stay away. 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 don't admire its beauty too long; its deadly poison can kill within seconds The poison arrow frog also stands out with its brightly colored skin. Its skin produces some of the strongest natural poison in the world, which Indigenous people often use for hunting purposes. Another animal with no friends is the hoatzin. Often called the stinkbird, it produces a horrible smell to scare

      This is also useful information if you are looking at the adaptations of the animals of a rainforest.
  • An average of 35 species becomes extinct every day in the world's tropical rainforests.
    • Chloe W
       
      Most of these species, we haven't discovered their uses yet. We don't care that we don't even know what they are and never will
  • Rivers have become both overfished and polluted. Gillnets now allow fishermen to kill huge amounts of fish at a time. They often use only the larger and more profitable fish, dumping the dead smaller fish and other animals such as dolphins back into the rivers.
    • Chloe W
       
      This is terrible. We are losing our air supply, and now our water supply is getting polluted. I hope we can stop it.
  • 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. You've probably heard of some of them; jaguars, toucans, parrots, gorillas, and tarantulas all make their homes in tropical rainforests. But have you ever heard of the aye-aye? Or the okapi? There are so many fascinating animals in tropical rainforests that millions haven't been named or even identified yet. In fact, about half of all the world's species live in tropical rainforests.

      How can we save the animals
  • During the Ice Ages, the last of which occurred about 10,000 years ago, the frozen areas of the North and South Poles spread over much of the earth, causing huge numbers of extinctions. But the giant 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 75 -80 degrees F. the whole year, animals don't have to worry about freezing during cold winters or finding shade in the hot summers. They rarely have to search for water, as 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 endemic, or found nowhere else on earth. The maues marmoset, a species of monkey, wasn't discovered until recently. Its entire tiny population lives within a few square miles in the Amazon rainforest. It is so small, it could sit in a person's hand!

  • Leaf-cutter, or parasol ants, can rightfully be called the world's first farmers. They climb trees up to 100-feet tall and cut out small pieces of leaves. They then carry these fragments, weighing as much as 50 times their body weight, back to their homes. Sometimes they must travel 200 feet, equal to an average human walking about 6 miles with 5,000 lbs. on his/her back! The forest floor is converted to a maze of busy highways full of these moving leaf fragments. These ants don't eat the leaves they have collected, but instead bury them underground. The combination of leaves and substances that the ants produce such as saliva allows a type of fungus to grow. This fungus is the only food that the ants need to eat. Azteca ants live on the swollen thorn acacia tree, which offers the ants everything needed for survival - lodging, water, and food for themselves and their young. In return, the ants protect the trees from predators. Whenever the ants feel something brush against the tree, they rush to fiercely fight the intruder. They also protect it from vines and other competing plants that would otherwise strangle it. As a result, nothing can grow near these trees. They are the only trees with a built-in alarm system!

      There are many people in the rainforest the main tribes are the Huli the Pygmies Yanomami who are protected by the government. They often have diffrent belifes as it is very rare to find same tribe in another place. Many tribes have not yet been out of the depths of our world and are totaly disconeccted but they now that there are others out there. But because of deforesttation the tribes will soon be in contact with our world and forget there ways of living.
  • Of these varying Amer-Indian people living in the Amazon Rainforest, one of the largest groups is the Yanomami.  “Yano” translates to “communal house”.  Their village life is centered around the “yano”, or communal house.  The “yano” is a large, circular shelter constructed of vine and leaf thatch, which has a living space in the middle.   Village activity revolves around the main house which has multiple living quarters built in the center.

    At one time almost 10 million native Indians occupied the lands of the South America Rainforest. At the time when Western and European explorers and conquistadors invaded the land in search of untold riches, there were less than one million indigenous people, today there are less than 250,000 indigenous natives. As the Rainforest dies, so does the heritage of the land and sadly so do the people of the Rainforest. The remarkable human diversity here has over 215 ethnic groups speaking 170 different languages in an area composing 190 million acres of land - roughly twice the size of California. 188 million acres of this land remains inside the Brazilian Amazon, in the states of Acre, Amapa, Amazonas, Maranhao, Mato Grosso, Para, Rondonia, Roraima, and Tocantins.

Pygmy Tribes, include Baka and Mbuti Pygmies, like the Bushmen of the Kalahari in Africa, are some of the last remaining "hunter-gatherers". Totally self-sufficient, these many Amazonian Indian Tribes have called the Amazon Rainforest home for centuries now. The Huli Indian Tribe are one of many who make their home in the remote highland forests of Papua New Guinea. In their culture, men and women live in large groups in separate quarters. The people of the Amazon are highly intelligent, even though many have never seen any modern technology. They live by the earth and the sea and have developed an extreme affinity with nature. Their ritual ceremonies and beliefs in their lives are often governed by nature. They look between the l

  • Two drugs obtained from a rainforest plant known as the Madagascar periwinkle, now extinct in the wild due to deforestation of the Madagascar rainforest, have increased the chances of survival for children with leukemia from 20 percent to 80 percent. Think about it: eight out of ten children are now saved, rather than eight of ten children dying from leukemia. How many children have been spared and how many more will continue to be spared because of this single rainforest plant? What if we had failed to discover this one important plant among millions before human activities had led to its extinction? When our remaining rainforests are gone, the rare plants and animals will be lost forever-and so will the possible cures for diseases like cancer they can provide.
    • Marius S
       
      Because of deforestation, all this has happened!
  • Rainforests have evolved over millions of years to turn into the incredibly complex environments they are today. Rainforests represent a store of living and breathing renewable natural resources that for eons, by virtue of their richness in both animal and plant species, have contributed a wealth of resources for the survival and well-being of humankind. These resources have included basic food supplies, clothing, shelter, fuel, spices, industrial raw materials, and medicine for all those who have lived in the majesty of the forest. However, the inner dynamics of a tropical rainforest is an intricate and fragile system. Everything is so interdependent that upsetting one part can lead to unknown damage or even destruction of the whole. Sadly, it has taken only a century of human intervention to destroy what nature designed to last forever. The scale of human pressures on ecosystems everywhere has increased enormously in the last few decades. Since 1980 the global economy has tripled in size and the world population has increased by 30 percent. Consumption of everything on the planet has risen- at a cost to our ecosystems. In 2001, The World Resources Institute estimated that the demand for rice, wheat, and corn is expected to grow by 40% by 2020, increasing irrigation water demands by 50% or more. They further reported that the demand for wood could double by the year 2050; unfortunately, it is still the tropical forests of the world that supply the bulk of the world's demand for wood.

      rainforest could be gone if the wood suplies keeps going up like this!
  • In 1950, about 15 percent of the Earth's land surface was covered by rainforest. Today, more than half has already gone up in smoke. In fewer than fifty years, more than half of the world's tropical rainforests have fallen victim to fire and the chain saw, and the rate of destruction is still accelerating. Unbelievably, more than 200,000 acres of rainforest are burned every day. That is more than 150 acres lost every minute of every day, and 78 million acres lost every year! More than 20 percent of the Amazon rainforest is already gone, and much more is severely threatened as the destruction continues. It is estimated that the Amazon alone is vanishing at a rate of 20,000 square miles a year. If nothing is done to curb this trend, the entire Amazon could well be gone within fifty years. Massive deforestation brings with it many ugly consequences-air and water pollution, soil erosion, malaria epidemics, the release of carbon dioxide into the atmosphere, the eviction and decimation of indigenous Indian tribes, and the loss of biodiversity through extinction of plants and animals. Fewer rainforests mean less rain, less oxygen for us to breathe, and an increased threat from global warming.
    • Yen Yu C
       
      that is just scary but it is something we must know inorder for someone to solve the problem someday...i guess
  • But who is really to blame? Consider what we industrialized Americans have done to our own homeland. We converted 90 percent of North America's virgin forests into firewood, shingles, furniture, railroad ties, and paper. Other industrialized countries have done no better. Malaysia, Indonesia, Brazil, and other tropical countries with rainforests are often branded as "environmental villains" of the world, mainly because of their reported levels of destruction of their rainforests. But despite the levels of deforestation, up to 60 percent of their territory is still covered by natural tropical forests. In fact, today, much of the pressures on their remaining rainforests comes from servicing the needs and markets for wood products in industrialized countries that have already depleted their own natural resources. Industrial countries would not be buying rainforest hardwoods and timber had we not cut down our own trees long ago, nor would poachers in the Amazon jungle be slaughtering jaguar, ocelot, caiman, and otter if we did not provide lucrative markets for their skins in Berlin, Paris, and Tokyo.

      Useful for my Q4
  • he problem and the solution of the destruction of the rainforest are both economic. Governments need money to service their debts, squatters and settlers need money to feed their families, and companies need to make profits. The simple fact is that the rainforest is being destroyed for the income and profits it yields, however fleeting. Money still makes the world go around . . . even in South America and even in the rainforest. But this also means that if landowners, governments, and those living in the rainforest today were given a viable economic reason not to destroy the rainforest, it could and would be saved. And this viable economic alternative does exist, and it is working today. Many organizations have demonstrated that if the medicinal plants, fruits, nuts, oils, and other resources like rubber, chocolate, and chicle (used to make chewing gums) are harvested sustainably, rainforest land has much more economic value today and more long-term income and profits for the future than if just timber is harvested or burned down for cattle or farming operations. In fact, the latest statistics prove that rainforest land converted to cattle operations yields the landowner $60 per acre; if timber is harvested, the land is worth $400 per acre. However, if medicinal plants, fruits, nuts, rubber, chocolate, and other renewable and sustainable resources are harvested, the land will yield the landowner $2,400 per acre. This value provides an income not only today, but year after year - for generations. These sustainable resources - not the trees - are the true wealth of the rainforest.

Tropical Rainforest- Trivia & Facts on Saving - 0 views

  • Today, we know that the soil of the tropical rainforests is thin and very low in nutrients. Decomposers like leaf-cutter ants, termites, bacteria, and fungi quickly turn falling leaves and dead organisms into nutrients. Plants take up these nutrients the moment they are available, so they don’t get a chance to enrich the soil. Keeping Tropical Rainforests Healthy Conservation of tropical rainforests should be easy. They have survived for millions of years. The trick to keeping them healthy is to not take too much too fast. This gives the rainforests time to recover from human activities like logging. But many countries that have tropical rainforests are poor. They can make money by cutting down and developing the rainforests. But uncontrolled development results in deforestation

      About the rainforest cycle. (First Paragraph)
  • Rainforests have 170,000 of the world's 400,000 known plant species. The United States has 81 species of frogs, while Madagascar (which is smaller than Texas) may have 300 species. Europe has 321 butterfly species, while Manu National Park in the tropical rainforest of Peru has 1,300 species! The world’s only species of flying snake and lizard live in the Borneo rainforest. The largest catfish in the world lives in a tropical rainforest river in Vietnam. It weighs over 300 kg. About one-quarter of all the medicines we use come from rainforest plants. Curare comes from a tropical vine. It is used as an anesthetic and to relax muscles during heart surgery. Quinine, from the cinchona tree, is used to treat malaria. A person with leukemia has a 99% chance that the disease will go into remission because of the rosy periwinkle. More than 1,400 varieties of tropical plants might be potential cures for cancer.

  • More than half the species on Earth are found in tropical rainforests. Many species living in these forests have never before been seen or studied by scientists. Most of these unknown species are insects, like moths.
  • Tropical rainforests are wet nearly all the time. They get lots of rain all year long, but they also help make rain through evaporation. Tropical rainforests help regulate weather all over the world.
  • Tropical rainforests are found in a narrow region around the equator that is known as the tropics. The climate is rainy and the temperatures are warm and nearly the same every day. The sun and the rain combine to create an environment that is very humid. This climate is ideal for the growth of many kinds of green plants.
  • Many different frog species live in the canopy of the rainforest. Most spend their entire lives in the canopy. They lay their eggs in little pools of water held in leaves instead of in ponds or streams.
  • Tropical rainforest plants have many adaptations for living in the forest. Some collect all their water from the air. For this reason, many of them have very large leaves. Others have flexible stems that allow them to bend and follow the sunlight so they can carry out photosynthesis all day.

Deforestation - 0 views

  • What is Deforestation Deforestation is defined as the destruction of forested land. It has proved to be a major problem all over world. However, the rates of destruction of forests are particularly high in the tropics. Causes of Deforestation The causes of deforestation vary form place to place. The most common causes, however, are logging, agricultural expansion, wars, and mining, Effects of Deforestation Deforestation has been the cause of many problems facing the world today such as erosions, loss of biodiversity through extinction of plant and animal species, and increased atmospheric carbon dioxide. Importnace of Vegetation Deforestation consequently decrease the supply of oxygen found on earth. Oxygen is essential to the existence of all living things and without it every living creature (including humans) will not be able to sustain life. In addition, forests provide homes for many important species such as the Northern Spotted Owl which can only survive in the northwestern United States .

Macaws - 0 views

  • Macaws are herbivores. They eat primarily seeds, nuts, and fruit. Using their impressive beaks, they have no problem opening even the toughest seed.

  • First they scratch a thin line with their beak’s sharp point, and then they shear the seed open. But inside some of those seeds are poisonous chemicals. How can macaws eat the seeds without getting sick or dying? They visit clay licks—the rainforest’s natural “drugstores.”
  • The Amazon rainforest has more than 100 of these special clay- and mineral-rich areas along riverbanks.

  • Most macaws live in South and Central America. However, at least two species—scarlet macaws and military macaws—can be found in Mexico as well. Most macaws live in tropical rainforests, where they make nests in holes in trees, but some live in other habitats.
    • Elizabeth B
       
      look on diigo to remember this note.
  • Macaws face two major threats: habitat destruction and the pet trade. Places where macaws live are being destroyed mostly as a result of deforestation. More than 18,000 square kilometers of Amazon rainforest are cut down every year. That’s an area larger than the state of Connecticut in the United States! So many macaws have been captured and sold into the pet trade that this has become a serious problem.
  • macaws mate for life. They form breeding pairs called pair bonds that live together, groom each other, and share food. Macaws lay eggs once a year. Breeding seasons generally begin in late fall or early winter.

Benefits of Deforestation - 0 views

  • One of the easiest benefits of deforestation to spot are the economic ones. Lumber products are one of the most staple constructive materials in human society. Whether it's raw lumber used for making tables and houses, or paper and other wood by-products, we simply cannot live without the use of lumber. Like steel and stone, wood is one of the most basic natural resources, and unlike steel and stone, it is renewable simply by growing more trees. The only real trick to balancing it's consumption is to grow more trees to replace the ones taken.

Like steel and stone, wood is one of the most basic natural resources, and unlike steel and stone, it is renewable simply by growing more trees. The only real trick to balancing it's consumption is to grow more trees to replace the ones taken. On a similarly related note, keep in mind that a lot of jobs revolve around the use of lumber. Wood cutters aside, there are those who work in processing plants to make glue from wood sap, process pulp into paper, and others. This is another benefit of deforestation; it opens more job opportunities for people who would otherwise be unemployed. These job opportunities are more than simply a humanitarian concept; society at large would suffer if all of the people working in the wood industry were to suddenly find themselves jobless. This benefit of deforestation not only covers the people who cut down trees and process them, but also extends to the people who "clean up" after them. For every patch of forest cut down, arable land becomes available for farmers, or can be used as an area to place urban living sites like apartments, houses, and buildings.

Or, if the city/government mandates replanting trees to replace the lost ones, then jobs are also provided for those people who do the seeding after a patch of forest is stripped. Thinking about it, the cleared areas are places which provide a lot of potential for growth, and this is yet another benefit of deforestation. As stated above, arable land is valuable, and the act of deforestation to clear a place for farm land provides a much needed additional food source for man. More often than not, the

Monkeys - 0 views

  • Lifespans The lifespan of monkeys depends on the species. In the wild, squirrel monkeys can live up to 20 years. Squirrel monkeys spend their lives in trees and are vulnerable as prey for eagles. Howler monkeys live 15 to 20 years in the wild. Howler monkeys have been hunted and their habitats have been destroyed. This greatly decreases the lifespan of the species. Mandrills live up to 45 years in the wild. They are also hunted for food.
  • The branches shake and dark objects scatter across the treetops. If you are standing in the tropical forest you probably just heard monkeys over your head. Agile and acrobatic monkeys easily leap through the forest but are often difficult to see and study. Most monkeys live in tropical regions in the Americas, Africa, and Asia and spend much of their lives in treetops. Monkeys belong to a larger group of mammals called primates. Primates have large brains, grasping hands and include lemurs, apes and humans.

Degrowth - Wikipedia, the free encyclopedia - 0 views

  • Ecological footprint Main article: Ecological footprint The ecological footprint is a measure of human demand on the Earth's ecosystems. It compares human demand with planet Earth's ecological capacity to regenerate. It represents the amount of biologically productive land and sea area needed to regenerate the resources a human population consumes and to absorb and render harmless the corresponding waste. According to a 2005 Global Footprint Network report,[7] while inhabitants of high-income countries live off of 6.4 global hectares (gHa), while those from low-income countries live off of a single gHa. For example, while each inhabitant of Bangladesh lives off of what they produce from 0.56 gHa, a North American requires 12.5 gHa. Each inhabitant of North America uses 22.3 times as much land as a Bangladeshi. Of the 12.5 hectares used by the North American, 5.5 is located in the United States, and the rest is found in foreign countries.[7] According to the same report, the average number of global hectares per person was 2.1, while current consumption levels have reached 2.7 hectares per person. In order for the world's population to attain the living standards typical of European countries, the resources of between three and eight planet Earths would be required. In order for world economic equality to be achieved with the current available resources, rich countries would have to reduce their standard of living through degrowth. The eventual reduction of all available resources would lead to a forced reduction in consumption. Controlled reduction of consumption would reduce the trauma of this change.
  • Degrowth and Sustainable Development Degrowth thought is in opposition to all forms of productivist economics. It is, thus, also opposed to sustainable development. While the concern for sustainability does not contradict degrowth, sustainable development is rooted in mainstream development ideas that aim to increase capitalist growth and consumption. Degrowth therefore sees sustainable development as an oxymoron[8], as any development based on growth in a finite and environmentally stressed world is seen as inherently unsustainable. Since current levels of consumption exceed the Earth's ability to regenerate these resources, economic growth will lead to their exhaustion. Those in favor of sustainable development argue that continued economic growth is possible if consumption of energy and resources is reduced. Furthermore, growth-based development has been shown to be more effective in expanding social inequality, concentrating wealth in the hands of a few, than in actually generating more wealth and increasing living standards[9][10]. Critics of degrowth argue that a slowing of economic growth would result in increased unemployment and increase poverty. Many who understand the devastating environmental consequences of growth still advocate for economic growth in the South, even if not in the North. But, a slowing of economic growth would fail to deliver the benefits of degrowth—self-sufficiency, material responsibility—and would indeed lead to decreased employment. Rather, degrowth proponents advocate for a complete abandonment of the current (growth) economic system, suggesting that relocalizating and abandoning the global economy in the Global South would allow people of the South to become more self-sufficient and would end the overconsumption and exploitation of Southern resources by the North

  • Many species of animal life can be found in the rain forest. Common characteristics found among mammals and birds (and reptiles and amphibians, too) include adaptations to a life in the trees, such as the prehensile tails of New World monkeys. Other characteristics are bright colors and sharp patterns, loud vocalizations, and diets heavy on fruits. Insects make up the largest single group of animals that live in tropical forests. They include brightly colored butterflies, mosquitoes, camouflaged stick insects, and huge colonies of ants. The Amazon river basin rainforest contains a wider variety of plant and animal life than any other biome in the world. The second largest population of plant and animal life can be found in scattered locations and islands of Southeast Asia. The lowest variety can be found in Africa. There may be 40 to 100 different species in 2.5 acres ( 1 hectare) of a tropical rain forest.   When early explorers first discovered the rainforests of Africa, Southeast Asia and South America, they They were amazed by the dense growth, trees with giant buttresses, vines and epiphytes . The tropical vegetation grew so dense that it was difficult to cut one's way through it. It was thought at the time that the soil of a rainforest must be very fertile, filled with nutrients, enabling it to support the immense trees and other vegetation they found. Today we know that the soil of the tropical rainforests is shallow, very poor in nutrients and almost without soluble minerals. Thousands of years of heavy rains have washed away the nutrients in the soil obtained from weathered rocks. The rainforest has a very short nutrient cycle. Nutrients generally stay in an ecosystem by being recycled and in a rainforest are mainly found in the living plants and the layers of decomposing leaf litter. Various species of decomposers like insects, bacteria, and fungi make quick work of turning dead plant and animal matter into nutrients. Plants take up these nutrients the moment they are released. A study in the Amazon rainforest found that 99% of nutrients are held in root mats. When a rainforest is burned or cut down the nutrients are removed from the ecosystem. The soil can only be used for a very short time before it becomes completely depleted of all nutrients.

  • Besides these four layers, a shrub/sapling layer receives about 3 % of the light that filters in through the canopies. These stunted trees are capable of a sudden growth surge when a gap in the canopy opens above them. The air beneath the lower canopy is almost always humid. The trees themselves give off water through the pores (stomata) of their leaves. This process, called transpiration, can account for as much as half of the precipitation in the rain forest. Rainforest plants have made many adaptations to their environment. With over 80 inches of rain per year, plants have made adaptations that helps them shed water off their leaves quickly so the branches don't get weighed down and break. Many plants have drip tips and grooved leaves, and some leaves have oily coatings to shed water. To absorb as much sunlight as possible on the dark understory, leaves are very large. Some trees have leaf stalks that turn with the movement of the sun so they always absorb the maximum amount of light. Leaves in the upper canopy are dark green, small and leathery to reduce water loss in the strong sunlight. Some trees will grow large leaves at the lower canopy level and small leaves in the upper canopy. Other plants grow in the upper canopy on larger trees to get sunlight. These are the epiphytes such as orchids and bromeliads. Many trees have buttress and stilt roots for extra support in the shallow, wet soil of the rainforests. Over 2,500 species of vines grow in the rainforest. Lianas start off as small shrubs that grow on the forest floor. To reach the sunlight in the upper canopy it sends out tendrils to grab sapling trees. The liana and the tree grow towards the canopy together. The vines grow from one tree to another and make up 40% of the canopy leaves. The rattan vine has spikes on the underside of its leaves that point backwards to grab onto sapling trees. Other "strangler" vines will use trees as support and grow thicker and thicker as they reach the canopy, strangling its host tree. They look like trees whose centers have been hollowed out. Dominant species do not exist in tropical rainforests. Lowland dipterocarp forest can consist of many different species of Dipterocarpaceae, but not all of the same species. Trees of the same species are very seldom found growing close together. This bio diversity and separation of the species prevents mass contamination and die-off from disease or insect infestation. Bio diversity also insures that there will be enough pollinators to take care of each species' needs. Animals depend on the staggered blooming and fruiting of rainforest plants to supply them with a year-round source of food.
    • Gurupranav G
       
      Again, another useful peice of info if you are looking at the diversity of plants in the rainforest.
  • There are four very distinct layers of trees in a tropical rain forest. These layers have been identified as the emergent, upper canopy, understory, and forest floor. Emergent trees are spaced wide apart, and are 100 to 240 feet tall with umbrella-shaped canopies that grow above the forest. Because emergent trees are exposed to drying winds, they tend to have small, pointed leaves. Some species lose their leaves during the brief dry season in monsoon rainforests. These giant trees have straight, smooth trunks with few branches. Their root system is very shallow, and to support their size they grow buttresses that can spread out to a distance of 30 feet. The upper canopy of 60 to 130 foot trees allows light to be easily available at the top of this layer, but greatly reduced any light below it. Most of the rainforest's animals live in the upper canopy. There is so much food available at this level that some animals never go down to the forest floor. The leaves have "drip spouts" that allows rain to run off. This keeps them dry and prevents mold and mildew from forming in the humid environment. The understory, or lower canopy, consists of 60 foot trees. This layer is made up of the trunks of canopy trees, shrubs, plants and small trees. There is little air movement. As a result the humidity is constantly high. This level is in constant shade. The forest floor is usually completely shaded, except where a canopy tree has fallen and created an opening. Most areas of the forest floor receive so little light that few bushes or herbs can grow there. As a result, a person can easily walk through most parts of a tropical rain forest. Less than 1 % of the light that strikes the top of the forest penetrates to the forest floor. The top soil is very thin and of poor quality. A lot of litter falls to the ground where it is quickly broken down by decomposers like termites, earthworms and fungi. The heat and humidity further help to break down the litter. This organic matter is then just as quickly absorbed by the trees' shallow roots

  • The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches (125 to 660 cm.) of rain falls yearly. Rain forests belong to the tropical wet climate group. The temperature in a rain forest rarely gets higher than 93 °F (34 °C) or drops below 68 °F (20 °C); average humidity is between 77 and 88%; rainfall is often more than 100 inches a year. There is usually a brief season of less rain. In monsoonal areas, there is a real dry season. Almost all rain forests lie near the equator. Rainforests now cover less than 6% of Earth's land surface. Scientists estimate that more than half of all the world's plant and animal species live in tropical rain forests. Tropical rainforests produce 40% of Earth's oxygen. A tropical rain forest has more kinds of trees than any other area in the world. Scientists have counted about 100 to 300 species in one 2 1/2-acre (1-hectare) area in South America. Seventy percent of the plants in the rainforest are trees. About 1/4 of all the medicines we use come from rainforest plants. Curare comes from a tropical vine, and is used as an anesthetic and to relax muscles during surgery. Quinine, from the cinchona tree, is used to treat malaria. A person with lymphocytic leukemia has a 99% chance that the disease will go into remission because of the rosy periwinkle. More than 1,400 varieties of tropical plants are thought to be potential cures for cancer. All tropical rain forests resemble one another in some ways. Many of the trees have straight trunks that don't branch out for 100 feet or more. There is no sense in growing branches below the canopy where there is little light. The majority of the trees have smooth, thin bark because there is no need to protect the them from water loss and freezing temperatures. It also makes it difficult for epiphytes and plant parasites to get a hold on the trunks. The bark of different species is so similar that it is difficult to identify a tree by its bark. Many trees can only be identified by their flowers. Despite these differences, each of the three largest rainforests--the American, the African, and the Asian--has a different group of animal and plant species. Each rain forest has many species of monkeys, all of which differ from the species of the other two rain forests. In addition, different areas of the same rain forest may have different species. Many kinds of trees that grow in the mountains of the Amazon rain forest do not grow in the lowlands of that same forest.

Elephants - 0 views

  • Elephants are the largest land animals. They can weigh over 6,000 kg, or more than the weight of four cars! The one feature that makes an elephant unmistakable is its long trunk. A trunk is an elephant's best tool for sucking up water, digging, grabbing, lifting, sniffing, and breathing. The trunk even has a fingerlike tip that can flick dirt from an elephant’s eye or pick up a single blade of grass. There are three species of elephants. Two species live in Africa and one lives in Asia. All three species are endangered.
  • Asian elephants have an arched body shape. They have triangular ears that do not reach their shoulders and two bumps on their foreheads. Their trunks have a single lip on the upper tip of the trunk. Male Asian elephants are 2-3.5 m tall. Their average weight is about 5,400 kg. Females average about 2.35 m tall and weigh about 2,700 kg. Often, only males have tusk
  • Elephants live in social groups called herds. Herds usually have about 10 to 20 members. Sometimes many herds will meet and form “super herds” of 100 or more elephants. Herds consist mainly of females that are related to each other. A typical herd might include mothers, daughters, aunts, and grandmothers, and a few young males. The oldest female is the herd’s matriarch. She leads the herd to water and finds food and a place to rest. There are also smaller bachelor herds that are made up of adult males.

A male may grow to be twice as large as a female of the same age. In the wild, elephants live to be about 60-years-old.
  • People have always been amazed at the great size and strength of elephants. Long ago, elephants were sometimes used on the battlefield. Soldiers riding atop them would charge at the enemy. The sight of a giant elephant in armor could terrify the enemy soldiers into running away. In Asia, elephants are trained to work for people. They carry people and supplies through tropical forests and help with logging by moving giant logs from place to place. Asian elephants have even been used as taxis to carry people through slow traffic. In India, Thailand, and other Asian countries, elephants are honored as symbols of good fortune. People sometimes decorate elephants and include them as part of traditional religious ceremonies.
  • In the early 1900s, there were more than 5 million elephants in Africa and Asia. Today, there are fewer than 500,000, as a result of hunting (legal and illegal) and habitat destruction. People are the biggest threat to the survival of elephants both in Africa and Asia.

  • Rainforests are home to half of all the living animal and plant species on the planet.[2] Tropical rain forests are called the "world's largest pharmacy" because over one-quarter of modern medicines originate from its plants.

  • The rainforest is divided into five different layers, each with different plants and animals, adapted for life in the particular area. These are: the floor layer, the shrub layer, the undercanopy layer, the canopy layer and the emergent layer. Only the emergent layer is unique to tropical rainforests, while the others are also found in temperate rainforests.

  • The emergent layer contains a small number of very large trees which grow above the general canopy, reaching heights of 45-55 m, although on occasion a few species will grow to 70 m or 80 m tall.

  • The undergrowth in a rainforest is restricted in many areas by the lack of sunlight at ground level.[4] This makes it possible for people and other animals to walk through the forest. If the leaf canopy is destroyed or thinned for any reason, the ground beneath is soon colonized by a dense tangled growth of vines, shrubs and small trees called a jungle.[5]

  • Canopy - This is the primary layer of the forest and forms a roof over the two remaining layers. Most canopy trees have smooth, oval leaves that come to a point. It's a maze of leaves and branches. Many animals live in this area since food is abundant.

  • Under canopy - Little sunshine reaches this area so the plants have to grow larger leaves to reach the sunlight. The plants in this area seldom grow to 12 feet

  • Shrub layer/forest floor - This layer is very dark. Almost no plants grow in this area, as a result. Since hardly any sun reaches the forest floor things begin to decay quickly. A leaf that might take one year to decompose in a regular climate will disappear in 6 weeks

  • An increase in tourism has increased economic support, allowing more revenue to go into the protection of the habitat. Tourism can contribute directly to the conservation of sensitive areas and habitat. Revenue from park-entrance fees and similar sources can be utilised specifically to pay for the protection and management of environmentally sensitive areas. Revenue from taxation and tourism provides an additional incentive for governments to contribute revenue to the protection of the forest. Tourism also has the potential to increase public appreciation of the environment and to spread awareness of environmental problems when it brings people into closer contact with the environment. Such increased awareness can induce more environmentally conscious behavior. Tourism has had a positive effect on wildlife preservation and protection efforts, notably in Africa but also in South America, Asia, Australia, and the South Pacific.[14]

Blue Planet Biomes - World Biomes - 0 views

  • A biome is a large geographical area of distinctive plant and animal groups, which are adapted to that particular environment. The climate and geography of a region determines what type of biome can exist in that region. Major biomes include deserts, forests, grasslands, tundra, and several types of aquatic environments. Each biome consists of many ecosystems whose communities have adapted to the small differences in climate and the environment inside the biome. All living things are closely related to their environment. Any change in one part of an environment, like an increase or decrease of a species of animal or plant, causes a ripple effect of change in through other parts of the environment. The earth includes a huge variety of living things, from complex plants and animals to very simple, one-celled organisms. But large or small, simple or complex, no organism lives alone. Each depends in some way on other living and nonliving things in its surroundings.

Rainforest Animals - 0 views

  • birds live in the canopy (upper leaves of the trees) and in the emergents (the tops of the tallest trees). Large animals (like jaguars) generally live on the forest floor, but others (like howler monkeys and sloths) are arboreal (living in trees). Insects are found almost everywhere.

  • Some animals try to convince predators that they are bigger and more fierce than they really are. For example, the larva of the lobster moth (Stauropus fagi), whose larva looks like a scorpion, but is in fact completely defenseless. Many butterflies have large "eye" designs on their wings. This makes them look like the head of a very large animal instead of a harmless butterfly, and scares many predators away.

The Food Chain - 0 views

    The Food Chain RealAudio Click here to be joined by your audio host! What is the difference between the 'Food Chain' and 'Food Web?' A popular misnomer, the 'food chain' is not actually a linear chain but a complex web. Energy is passed from one organism to another in a complex network like a spider's web. The food chain consists of four main parts: * The Sun, which provides the energy for everything on the planet. * Producers: these include all green plants. These are also known as autotrophs, since they make their own food. Producers are able to harness the energy of the sun to make food. Ultimately, every (aerobic) organism is dependent on plants for oxygen (which is the waste product from photosynthesis) and food (which is produced in the form of glucose through photosynthesis). They make up the bulk of the food chain or web. * Consumers: In short, consumers are every organism that eats something else. They include herbivores (animals that eat plants), carnivores (animals that eat other animals), parasites (animals that live off of other organisms by harming it), and scavengers (animals that eat dead animal carcasses). Primary consumers are the herbivores, and are the second largest biomass in an ecosystem. The animals that eat the herbivores (carnivores) make up the third largest biomass, and are also known as secondary consumers. This continues with tertiary consumers, etc. * Decomposers: These are mainly bacteria and fungi that convert dead matter into gases such as carbon and nitrogen to be released back into the air, soil, or water. Fungi, and other organisms that break down dead organic matter are known as saprophytes. Even though most of us hate those mushrooms or molds, they actually play a very important role. Without decomposers, the earth would be covered in trash. Decomposers are necessary since they recycle the nutrients to be used again by producers. This table shows the relational biomass of each of the major g
