Orangutans are apes found in the tropical rainforests of Borneo and Sumatra. There are two species, the Bornean orangutan and the Sumatran orangutan. Orangutans spend most of their time in trees eating fruits, leaves, flowers and bark. They are well adapted to an arboreal lifestyle with long arms for swinging between trees. Orangutans are endangered due to habitat loss and fragmentation as forests are cleared for agriculture, logging and palm oil plantations. Their populations have declined sharply over the past century and they now number around 55,000 remaining in the wild.

- 2. Food Web Tigers Sumatran Orangutan Flowers/Bark (10% of diet) Fruit (60% of diet) Leaves (20% of diet) Leopards Bornean Orangutan Ants/Termites/Pu pae/Crickets (5% of diet) Orangutans are eaten by Leopards and some tigers in Sumatra. Orangutans will spend 100% of their day eating, sleeping and travelling¡mostly likely in order to get food.They eat mostly fruits such as durian, jackfruit, figs, and rambutan.Young leaves, insects and flowers are a fallback food if fruit is unavailable to an orangutan.
- 3. Biomes ? There are two species of Orangutan, or Ponginae ? The Pongo pygmaeus, or Bornean orangutan, is native to the island of Borneo, Malaysia/Indonesia (the island of Borneo is shared by Mayalsia and Indonesia) ? The Pongo abelii, or Sumatran orangutan, are found on the island of Sumatra, Indonesia (it is more rare than the Bornean orangutan) ? The Pongo hooijeri is a prehistoric species of orangutan from the Pleistocene ofVietnam ? These three places are both tropical rainforest biomes ? The flowering plants and abundance of trees provide food and habitats for orangutans to live comfortably in
- 4. Orangutan Competition ? In general, orangutans do not need to compete with other orangutans or other animals for resources due to their usually solitary living habits ? However, aggressions may be formed over food especially common in fig trees ? Mature adults will usually win in any situations of competition being twice the size of female adults and sub adult males ? Orangutans will never eat other orangutans
- 5. Biodiversity ? Family: Hominidae ? Subfamily: Pongidae; the great apes including orangutans, gorillas, chimpanzees, and bonobos ? Genus: Pongo; includes gorillas and orangutans ? Species: Pongo pygmaeus (Bornean orangutan) Pongo abelii (Sumatran orangutan) ? Orangutans are related to gorillas the most out of apes being in the same genus ? Orangutans share 97% of the same DNA as humans ? Humans and orangutans have many similarities and it is suggested by some that humans and orangutans share a common ancestor that includes African apes
- 6. Adaptive Radiation ? Orangutans hardly ever traverse across the ground.The Bornean spends some time on the ground but the Sumatran will probably only stay in the tree canopies all their lives ? They live in tropical biomes and eat the tropical fruit within their reach. ? Therefore, orangutans will go where the food is.Their main sources of food have been in these tropical communities of Malaysia and Indonesia. ? Orangutans live in two places in the world, there are slight differences between the two species that live in one or the other of these places
- 7. Adaptions ? Orangutans are the largest arboreal animals in the world-they spend over 95% of their time in trees ? Males can have arm spans up to 8 feet long ? Quadrumanous scrambling- the unique way that they travel through the trees ? Long narrow hands and feet for grasping branches ? Short opposable thumbs and big toes help with hanging on tree bhanches and brachiation (hand over hand swinging from branches) ? Highly mobile hip and shoulder joints
- 8. Evolution ? Orangutans are part of the scientific order primates which contains all the monkeys, prosimians and apes living today ? Primates are one of the oldest surviving mammal groups, thought to go back at least 65 million years ? They inhabit almost every part of the world, non- human primates found predominantly inAfrica,Asia and Central and SouthAmerica. ? The Bornean orangutan is now endangered at about 41,000 and the Sumatran orangutan is now critically endangered at about 7,500 in population ? A century ago, there were more than 230,000 orangutans total
- 9. Primary and Secondary Succession? ? Orangutans live in habitats of Primary succession today ? The reason for their decline in population is due to clear cutting and initially the decrease of trees, land and resources that are essential to an orangutan life. ? If secondary succession were to take place in the orangutan wild habitats, they would become extinct ? The largest, most important contributor to orangutan survival are the tropical trees in which they live in and harvest food from ? If these trees were to disappear for centuries, orangutans would become extinct in that time ? (Another contributor to orangutan are palm oil plantations)
