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.

Primates - 0 views

  • Primates are a group of mammals that include prosimians, monkeys, and apes. Humans are primates, too. We are a type of ape. Most primates have hands and feet that can grasp, and many have tails. There are about 230 primate species. Most primates are found in tropical environments. The only great exception to this is humans. We live all over the planet. Almost all primates eat both plants and animals. Most primates are threatened or endangered.

Humans live all over the planet in almost every environment. ©G.Ellis/GLOBIO.org As primates evolved over the past 50-60 million years, two important things happened. 1) Their faces flattened and the eyes moved to the front of the head, giving them binocular vision. 2) They developed hands with separate fingers and opposable thumbs. This allowed them to grasp and hold on to branches and other objects. These two important developments make primates very different from all

  • Adult primates come in many different sizes. The pygmy marmoset is the smallest and weighs only 70 g. The largest primate is the gorilla. It may weigh as much as 181 kg!  Primate species live for different lengths of time, depending on their size. The mouse lemur is very small and lives about eight years. Chimpanzees, which are quite large, can live as long as some humans.

  • 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 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]

  • 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]

  • 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.

  • 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.

      A great peice of info if you want to look at the biodiversity of animals in a rainforest
  • 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.

  • 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.

      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.

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.

      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

  • An average of 35 species becomes extinct every day in the world's tropical rainforests.

      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.
    • Shaian R
       
      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!

  • The harpy eagle nests in the tallest trees and hunts birds, monkeys, and sloths. Swinging through the lower branches, the grey woolly monkey uses its tail to grip. But this is gradually being destroyed. The Amazon Basin once dense, is now rapidly being opened up. The land is being developed for oil, mining, and farming.

  • The Sumatran rhinoceros is a small, hairy rhinoceros which survives in limited numbers in pockets of Indonesian and Malaysian rain forests. In the early 1900s it ranged over most of Southeast Asia from the Himalayas in Bhutan, eastern India through Malaysia, Sumatra and Borneo. Now they are only found in little forest pockets on the Indonesian island of Sumatra and the Malay peninsula.

  • The smallest living rhinoceros, the Sumatran rhinoceros has a gray-brown leathery hide. Its deep folds around the neck, behind the front legs, and before the hind legs give the rhinoceros an armor-plated appearance. It has a short, stocky body and stumpy legs which are covered with coarse reddish-brown hair. Its body length is from 8 to 8.5 feet and stands 4.5 feet at the shoulders. A mature rhino weighs from 2200 to 4400 pounds.
  • The Sumatran rhinoceros is the only Asian rhinoceros with two horns. Both sexes of rhinos have horns, the front horn being larger, averaging 15 to 20 inches. The male's horns are usually bigger than the female's, whose second, smaller horn is often absent. The upper lip curves down and can move around to grasp objects.
  • ...10 more annotations...
  • Information about the Sumatran rhino has been difficult to come by because it survives in small, scattered populations in the thick undergrowth of their rainforest habitat. It is known that the females have territories of about 1.2 to 2.2 miles in diameter that partially overlap with other females. The males seem to be nomadic. The estimated density per animal is approximately one animal per 15 sq. miles in high density areas, and one animal per 31 to 46 sq. miles in low density areas.
  • They live in a variety of habitats, but prefer higher elevations in the mountain moss forests and tropical rain forests with few human developments. The rhinos are most often found near water, and spend much of the day in mud wallows, which they dig out themselves and whose perimeters are kept clean. The wallows help the rhino avoid biting insects and protects them from the heat .
  • Sumatran rhinos are solitary animals who only come together to breed. Breeding of captive Sumatran rhinos has shown that the female will not come into estrus until she senses the nearness of a male. This reduces energy spent on cycling when the rhinos don't come into contact with each other on a regular basis. Gestation is 475 days with one calf per birth. The calf is covered with a dense coat of reddish hair. Calves are weaned at 18 month, but stay close to their mother for 2 to 3 years. Females reach sexual maturity at 4 years, and males take 7 years to reach sexual maturity. Birth intervals between calves is 3 to 4 years. The life span of captive rhinos is around 35 years.
  • Rhinos feed just before dawn and after dusk and move about during the night. The normal diet of the Sumatran rhino includes wild durian mangoes, figs, bamboo and plants species characteristic of disturbed forests. It will knock down saplings to get at the tender leaves. They are very fond of salt licks and each territory will include one.
  • The Sumatran rhinoceros is the smallest and rarest rhinoceros species. There are thought to be only 300 animals still in existence and the IUCN has put it on its critically endangered list in 1996. These survive in very small and scattered populations, their habitat fragmented into smaller and smaller pieces by encroaching human populations. The number of Sumatran rhinos has declined 50% due to poaching in the last 10 years. There are no signs that the situation is stabilizing. Efforts have been made by IUCN to set up a 3 year program for the protection to the Sumatran rhino in Indonesia and Malaysia in the wild. They are seeking to extend the program, whose funding ended in 1998. Captive breeding programs have also been set up, but have not been very successful. Since 1984 40 rhinos have been captured to participate in breeding programs, but 19 of these have died. Artificial insemination efforts have also not been very successful. These failures were the result of lack of knowledge of the diet and reproduction of the Sumatran rhinoceros. Experience so far has shown that the rhinos need larger enclosures with more natural conditions. Time is running out as efforts to save the Sumatran rhinoceros from extinction continue.

Layers of a Rainforest - 0 views

  • The tallest trees are the emergents, towering as much as 200 feet above the forest floor with trunks that measure up to 16 feet around.   Most of these trees are broad-leaved, hardwood evergreens. Sunlight is plentiful up here.  Animals found are eagles, monkeys, bats and butterflies. CANOPY LAYER 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.   Those animals include: snakes, toucans and treefrogs. UNDERSTORY LAYER 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.  Many animals live here including jaguars, red-eyed tree frogs and leopards.  There is a large concentration of insects here. FOREST FLOOR It's very dark down here.  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.   Giant anteaters live in this layer.

  • The Amazon is the world's largest and most famous rainforest. The Amazon River Basin is roughly the size of the forty-eight contiguous United States (the United States not including Alaska and Hawaii) and includes parts of eight South American countries: Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana, and Suriname. The basin is drained by the Amazon River, the world's largest river (and the second longest river after the Nile). The Amazon is home to more species of plants and animals than any other ecosystem on the planet and perhaps 30% of the world's species are found there. Some of the better known animals found in the Amazon include the jaguar, tapir, and many kinds of monkeys.
