Most nonhuman primates live in tropical and subtropical areas of the new world and old world. Most primates live an arboreal lifestyle, that is, they travel, eat, and sleep in the tops of trees. Even the larger apes, like chimpanzees and orangutans, usually sleep in leafy nests they make in trees. The most notable exceptions to this behavior are gorillas and humans. Both are ground dwellers.

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.

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.

Because there are so many creatures living in the rainforest, there is a great deal of competition for food, sunlight and space. Some animals became very specialised. This means that they adapted to eating a specific plant or animal that few others eat. For example, parrots and toucans eat nuts, and developed big strong beaks to crack open the tough shells. Leafcutter ants climb tall trees and cut small pieces of leaves which they carry back to their nest.The leaf pieces are about 50 times their weight.The ants bury the leaf pieces, and the combination of the leaves and the ants' saliva encourages the growth of a fungus, which is the only food these ants eat. Sometimes there are relationships between animals and plants that benefit both. Some trees depend on animals to spread the seeds of their fruit to distant parts of the forest. Birds and mammals eat the fruits, and travel some distance before the seeds pass through their digestive systems in another part of the forest. One problem with specialisation is that if one species becomes extinct, the other is in danger too unless it can adapt in time. The dodo, a flightless bird of Mauritius, became extinct in 1681. Today there are just 13 calvaria trees left on the island, each over 300 years old, and nearly at the end of their life. Scientists realised that the seeds had to pass through a dodo's digestive system before they could germinate. It seemed that the tree species would also become extinct, but scientists tried domestic turkeys and have successfully managed to germinate some seeds.Many rainforest animals use camouflage to 'disappear' in the rainforest. Stick insects are perfect examples of this. There are some butterflies whose wings look like leaves. Camouflage is of course useful for predators too, so that they can catch prey that hasn't seen them. The Boa Constrictor is an example of a camouflaged predator. The South American three-toed sloth uses camouflage and amazing slowness to escape predators. Green algae grows in the sloth's fur, which helps camouflage it in the forest canopy. Sloths are among the slowest moving animals of all (inside too, as it takes about a month to digest food). They hang from branches in the canopy, and are so still that predators such as jaguars don't see them. Some animals are poisonous, and use bright colors to warn predators to leave them alone. There are several species of brightly colored poison arrow frogs. Native Central and South American tribes used to wipe the ends of their arrows onto the frog's skin to make their arrows deadly

This spotted cat most closely resembles the leopard physically, although it is usually larger and of sturdier build and its behavioral and habitat characteristics are closer to those of the tiger. While dense rainforest is its preferred habitat, the jaguar will range

The jaguar is a near threatened species and its numbers are declining. Threats include habitat loss and fragmentation. While international trade in jaguars or their parts is prohibited, the cat is still regularly killed by humans, particularly in conflicts with ranchers and farmers in South America.

The jaguar prefers large prey and will take deer, capybara, tapirs, peccaries, dogs, foxes, and sometimes even anacondas and caiman. However, the cat will eat any small species that can be caught, including frogs, mice, birds, fish, sloths, monkeys, and turtles;

A food chain is the sequence of who eats whom in a biological community (an ecosystem) to obtain nutrition. A network of many food chains is called a food web. The food chain starts with plants or other autotrophs (organisms that make their own food from light and/or chemical energy) - these organisms are called primary producers. The primary producers are eaten by herbivores (plant-eaters) called primary consumers. The herbivores are eaten by carnivores (meat-eaters) and omnivores (animals that eat both animals and plants) - these organisms are called secondary consumers. Secondary consumers may be eaten by other carnivores called tertiary consumers. When any organism dies, it is eaten by tiny microbes (detrivores) and the exchange of energy continues.

A Food Pyramid in the Hot Desert Biome      Here we see a food pyramid that shows how the Kilocalories pass up the food chain.      The first trophic level is occupied by the primary producers, which are the plants.  Plants make food through photosynthesis. The limiting factor for these plants is the shortage of water, so they produce fewer than 200 Kilocalories of food for the animals for each square meter each year.     The primary consumers, who eat the plants, occupy the second trophic level. These animals have very little to eat, and are small. Many are insects, or reptiles, who are cold blooded and who use less energy to maintain their bodies than mammals and birds do. As food for predators, they provide about 20 Kilocalories per square meter per year for predators.      The predators are the secondary consumers. They occupy the third trophic level. Again we see cold-blooded animals, such as snakes, insect-eating lizards, and tarantualas. Only about 2 Kilocalories per square meter per year are stored in their bodies. In the harsher desert environments, they are the top predators.     In areas where deserts get more rain, more plant material is produced and a few tertiary consumers may be able to survive. They form a fourth trophic level.      This diagram shows the energy available at each trophic level in the hot desert biome. These numbers tell about the numbers of Kilocalories per square meter per year.  Cold Desert Energy Pyramid  Introduction to Desert Biomes  Return to Introduction to Biomes © Elizabeth Anne Viau, 1999.

The boa constrictor is one of the largest snakes in the world, ranging in size from 10 to 14 feet long.  The boa is very large, but the anaconda in South America is larger.  Most boa constrictors live in Guiana and Brazil.  Boas defend themselves by striking.    The boa is a constrictor, which means it wraps around its prey tighter and tighter until their prey dies.  Whenever its prey breathes out, the boa wraps tighter.  After the prey has been constricted, the boa eats it whole.  Boas eat mice and rats, and occasionally a small deer. To eat bigger things (like deer), they stretch their mouths very wide by unhinging their jaws.  It can take several weeks for the boa to fully digest its food.     Boa constrictors vary in color from brown to gray.  A large female can give birth to as many as 50 young!  Boas use heat pits to sense their surroundings, because they have bad eyesight. 

The Orangutan lives on the islands of Borneo and Sumatra in Indonesia.

The Orangutan eats tropical fruit and also leaves, bark and insects at times.

Male Orangutans weigh approximately 100 - 250 lbs and are about 4 - 5 ft. in height.  Female Orangutans will weigh approximately 60 - 110 lbs and are about 3 - 3.5 ft. in height.

All Grown Up Male orangutans are large apes. They are generally more than twice the size of females. Males may weigh around 90 kg. Females rarely reach 40 kg. ©G.Ellis/GLOBIO.org Around the age of

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.

Kabul, the capital of Afghanistan, is a multi-ethnic city and has always been so. As the seat of government for the Afghan kings, food was an important part of royal life. Chefs were commissioned from all over the empire and places afar. They are credited for creating a myriad of dishes, blending different styles and in the process creating the best examples of true Afghan cooking. Their creations include exotic kormas, palaos, sumptuous rice dishes, desserts, and other creative items. These royal chefs passed down their art to the aristocratic denizens of Kabul and they in turn to others. Several attempts were made to record the arts of the royal chefs. Two have been published. The first one, published in Afghanistan in the early 1900s recorded the ingredients and cooking styles of Afghanistan's monarchy. The second, called Aushpazi, by Wali Zikria, published in the United States in English, during the early 1990s, was essentially the cookbook of one of Afghanistan's royal houses.

SavannaSavanna is grassland with scattered individual trees. Savannas of one sort or another cover almost half the surface of Africa (about five million square miles, generally central Africa) and large areas of Australia, South America, and India. Climate is the most important factor in creating a savanna. Savannas are always found in warm or hot climates where the annual rainfall is from about 50.8 to 127 cm (20-50 inches) per year. It is crucial that the rainfall is concentrated in six or eight months of the year, followed by a long period of drought when fires can occur. If the rain were well distributed throughout the year, many such areas would become tropical forest. Savannas which result from climatic conditions are called climatic savannas. Savannas that are caused by soil conditions and that are not entirely maintained by fire are called edaphic savannas. These can occur on hills or ridges where the soil is shallow, or in valleys where clay soils become waterlogged in wet weather. A third type of savanna, known as derived savanna, is the result of people clearing forest land for cultivation. Farmers fell a tract of forest, burn the dead trees, and plant crops in the ashes for as long as the soil remains fertile. Then, the field is abandoned and, although forest trees may recolonize, grass takes over on the bare ground (succession), becoming luxuriant enough to burn within a year or so. In Africa, a heavy concentration of elephants in protected parkland have created a savanna by eating leaves and twigs and breaking off the branches, smashing the trunks and stripping the bark of trees. Elephants can convert a dense woodland into an open grassland in a short period of time. Annual fires then maintain the area as a savanna.

The key species that supports almost all other ocean life is the Phaeton, a tiny, shrimp-like androgyne that is barely visible to the naked eye. Many species of fish and marine mammals eat primarily phaeton which float freely in the ocean's currents. Those species are, in turn, food for carnivorous predators, such as sharks, orcas, devil rays, and electric eels. When predators like these maul their prey, bits fall to the sea floor and decompose, providing a rich fertilizer for the "templa" or sea floor, one of the Ocean Biomes five layers. The second layer is the "firdga," (pronounced frid-ja) a very cool and dark band of stagnant water that supports moistly lampfish--species that use special lights on their bodies to navigate and find food. The third layer, the "fluvia," channels the strongest currents, but is too turbulent for most animal species. Most marine animals prefer to occupy the "luffa," the second layer from the surface wherein phaeton are abundant and light is able to penetrate and support plant life. The "nomar," the topmost ocean layer, which includes the surface of the ocean biome, also supports a few species, mostly flying-fish and damselflies, which use the surface to mate and hatch their young.

The taiga or coniferous forest is probably the world's largest land biome. It is located south of the tundra and stretches across portions of North America. Europe and Asia. During the summers, the soil remains very wet and is suitable for lichens and mosses. Fir and spruce trees grow well in this environment. The trees provide homes for many birds including the crossbill, which is capable of cracking cones to eat the seeds. A variety of animals are found in the taiga. They include moose, weasels. wolves, deer. Lynx, caribou, porcupines, beaver, mink and bears.

 INITIATION

The initiation lasts several days in a hidden place in the depths of the forest. After the boys to be initiated have been undressed, washed, shaved and palm oil is rubbed on their body, they are led into a special hut.

Then, they undergo multiple rituals, some public (such as dances and processions), some secret, for about a week during which they eat, drink and sleep very little.

The rainforest is an ideal place for many types of animals to live. There is plenty of water, shelter and food, and it is warm all year.

Many reptiles and amphibians also live in the forest. The most spectacular is the anaconda which can measure 9 metres. Others include the colourful, but deadly poisonous coral snake, the python and the carpet snake (a delicacy according to the natives who eat it

Tropical birds are also very numerous. Over 500 species are found in one small reserve in Costa Rica which is almost as many as the entire number of bird species found in the United Kingdom.

Hornbills are important to the tropical rainforest of Borneo. Their bills help them eat large fruits and carry seeds to new areas of the forest

The island of Borneo started as a single volcano beneath the sea. Millions of years ago, it erupted. Over time, smaller eruptions and earthquakes joined land together to form an island. Today, Borneo is the third largest island in the world. It is twice the size of Japan. Three countries share the island: Malaysia, Indonesia, and Brunei.

Over 16 million people live on Borneo. Borneo’s landscape and wildlife are diverse and include high mountains and rugged coastlines. Most of the island is covered with dense, ancient tropical rainforest. Borneo’s rare and endangered wildlife includes the orangutan, Asian elephant, proboscis monkey, flying frog, and many species of rare plants.
