Comparative Primate

Lemurs: Lemurs are native to Madagascar and found almost nowhere else in the world. The environment in Madagascar changes drastically at times from with a humid hot season to a dry season. Stereotypical lemurs are herbivores eating leaves and fruits. However mice and dwarf lemurs are omnivores eating the same as regular lemurs as well as small animals. While the lemurs do have preferred food they usually wont be too picky when hungry, eating anything the environment gives them. Which helps them surviv
e when fruit runs low during the drier seasons.



Spider Monkey: Spider Monkeys can be found in the rain forests of South America. The climate in these rain forests are usually warm and rainy. The Spider Monkey diet is similar to that of the Lemurs. The Spider Monkeys are usually omnivores eating fruits and seeds but also insects and even small bird eggs. When their is a large amount of food available the Spider Monkeys will usually live in large groups, if it is not a particular abundant food season they will live separately in order to get the food for themselves.

Baboon: The Baboons are native to Africa and are very adaptive to the environment around them. As long as Baboons have water and a tall place to sleep (like trees) they are set to live. Baboons are also mostly omnivores as well. They eat berries, seeds, leaves, fish, birds, hares, and even small antelopes. Like most primates the Baboons diet usually consists of whats around them in their environment. During seasons where food is scarce the Baboons could also eat bark, sap, and even velvet monkeys to survive.

Gibbon: Gibbons are found native in South Asia. The regions in which the Gibbons have active monsoon seasons and tend to be warm in temperature. Gibbons are also omnivores eating fruit, seeds, leaves, insects, spiders, and small birds. Gibbons, like other primates, are very adaptive to the surroundings around them in regards to their diet. When their preferred food source is low the Gibbon is able to eat whatever is necessary to survive.

Chimpanzee:
The Chimpanzee is normally found in central Africa. They are usually found in rain forests or areas that are near rain forests. These areas tend to be humid and dry at times. Like the other apes in this post the Chimpanzees are omnivores. They have no problem eating leaves, fruits, seeds, insects, and small bird eggs. Dr. Jane Goodall has even found that Chimps hunt for food. These Chimps are very adaptive to the surroundings around them in regards to their diet. If one food source is low they can survive off what is around them.

Summary: These primates share very similar characteristics in regards to their diets. Over the course of writing this post I found that these primates live in very similar environments and are able to thrive in the environments they do live in as long as they don't lose their homes to logging.

  1. In general, good descriptions and connections made with the environment for all five primates, but you miss a key point which would have explained even more of the dietary pattern. Three of these primates, lemurs, spider monkeys and gibbons, are predominately arboreal. This is usually for reasons of predation avoidance and defense, but this limits their dietary opportunity to what is in the trees and excludes them from what is available on the ground. Remember that "environment" isn't just the habitat, it also includes the organisms in that habitat, not just those might be food, but those that can also threaten the primate in question. That is a selection pressure as much as water or food availability might be.

    Conversely, baboons and chimpanzees, who are mostly terrestrial, are open to a wider variety of food items. They still have to worry about threats but have found other ways of dealing with it other than avoidance. This has a direct impact on diet.

    Okay on your summary, but digging a little deeper into environmental differences would have given you more insight into the dietary patterns. Good point on the logging, but this assignment addressed traits that have evolved over thousands of years, long before humans became a complication.

  2. Very interesting post I like the pictures where you see the animals eating and what they are eating. I think what you were writing about was very organized and set up the main conclusion of your post

  3. Just wanted to let you know that you have a squirrel monkey photo under the section for spider monkey. :)
