How do apes survive
Chimpanzees use more tools for more purposes than any other creatures except humans. A female chimp named Washoe knew more than signs. Chimpanzees in the wild rarely live longer than 50 years. Captive chimps can live more than 60 years.
Chimpanzees have a wide variety of tastes and are able to live in a wide variety of habitats, unlike gorillas and orangutans who have narrower diets.
Different chimpanzee groups use tools in different ways. Chimpanzees of the Tai Forest in Cote d'Ivoire crack open nuts with rocks, for example, while the Gombe chimps have never been seen doing this.
One of the chimpanzee calls is the "pant-hoot. Chimps groom each other. Grooming helps relations within the community and calms nervous or tense chimps. Male chimpanzees show their power in "displays. We carry within us physical evidence of the developmental processes and biological traits that humans share with all — yes, all — other organisms. What, if anything, unites primates as a single group, and how do primate adaptations reflects our evolutionary past? What did the earliest primates look like and how are they related to modern forms?
How has climate change influenced the diversification of different primate groups? How do primates navigate arboreal and terrestrial habitats?
What processes are involved in fossilization and in dating fossils from the distant past? Why do many primates live in groups? Why do some male primates commit infanticide? Why do some females form strong bonds? What do primates eat and how do they live in ecological communities with other animals? How do primates communicate? Do primates deceive each other? Unraveling the sociality and ecology of our closest living relatives, the non-human primates, can help us shed light on the selective pressures that shaped humans through evolutionary time.

Aa Aa Aa. Given the extreme diversity of living organisms on the planet many of which have not even been discovered yet , no one can study all species in a community.
Invariably, community ecologists study subsets of species within an assemblage. A taxocene , for example, is a subset of species sharing a common taxonomic classification. The monkeys and apes of Kibale National Park is an example of a taxocene: they are classified within the primate order Infraorder Catarrhini and live in the same forest in Uganda.
A guild is a subset of species within a community that use a set of resources in similar ways. An example of a guild is a nocturnal pollinating guild that might include prosimian primates, bats, and insects; these animal species are not closely related taxonomically, but are sympatric and consume the nectar of night-blooming flowers in similar ways. This essay focuses specifically on primates, and is thus an exploration into the community interactions in primate taxocenes.

Primates in communities.
Community ecologists have investigated species interactions and community structure since the early 20th century e. However, these topics have only more recently been investigated in primates more specifically as historically primatologists have tended to emphasize population ecology. Nonetheless, we are increasingly gaining insight into competition, predator-prey, parasite-host, and plant-primate interactions e.
In the following paragraphs, you will learn about the competitive, parasitic, predatory, and mutualistic interactions that primates have with other species — both plant and animal. Competitive Interactions Within a community, all species — including primates — occupy their own, unique niche. Predator-Prey Interactions. Primates as predators. Figure 3: A second level trophic level predator-prey interaction herbivory.

Since group-living increases the potential for intragroup feeding competition — , — , if there were no advantage to being social, it would not be expected to occur so commonly. One hypothesis is that it is the threat of predation that selects for social living in primates.
Virtually all primates are prey species, including the largest bodied primates — gorillas and chimpanzees. Primates are consumed as prey species by both terrestrial and aerial predators, including cats e. In Africa, the African crowned hawk-eagle Stephanoaetus coronatus is perhaps the most commonly identified predator and has been called a primate specialist predator. Humans prey upon primates as well; indeed, commercial hunting bushmeat trade is an exceptionally serious problem threatening primates in South America, Asia, and particularly Africa.
Primate Mutualisms. Polyspecific Associations. Some primate species, for example, form polyspecific associations in which social groups of two or more primate species aggregate. Others, however, appear to be non-random. Short term polyspecific associations are those that occur for relatively short periods of time but are observed more frequently — and are of longer duration — than would be expected by chance.
Long term polyspecific are particularly well-known among sympatric species of Saguinus in the Neotropics and Cercopithecus species in Africa. The functioning of these relatively permanent polyspecific associations may be quite different from those of short term and passing endurance. If polyspecific associations are not simply chance phenomena, then an adaptive reason for the existence of these mixed groups is expected, with at least one species benefitting, and no aspects of parasitism without some other mitigating benefit.
For example, in Kibale, in polyspecific associations among Cercopithecus ascanius , C. Seed dispersal. Figure 4.

Humans kill chimps in retaliation and to protect their families from future attacks. Bushmeat hunters target chimps because they provide more meat than smaller mammals, sometimes collecting their offspring as pets for themselves or to sell into the illegal pet trade.
And chimpanzees are susceptible to infectious diseases, too. Since the s, the Ebola virus has killed them in significant numbers. Chimpanzees are protected by national and international laws, including the U. Endangered Species Act. Some of their habitat is protected as sanctuaries or reserves, too. Conservation organizations are working to expand these protected areas, while also pushing for an end to the illegal killing and taking of the animals.
Key to securing the future of the chimpanzee, though, is improving its relationship with humans. All rights reserved. Animals Photo Ark. Common Name: Chimpanzees. Scientific Name: Pan troglodytes.
