However, the chimps did not exhibit normal hunting behavior, according to Pika. Unlike males who are ready to mate at any time of the year, female chimps are more open to copulation when they come into oestrus.

Males generally remain with their community for the rest of their lives but females will leave to join other chimpanzee communities. Chimps do sometimes hunt animals such as monkeys, and they may have taken the opportunity to kill the small gorillas for food. Female chimpanzees will reach sexual maturity at 13 years while males at 16. Pika can only speculate on why these unprecedented attacks occurred. Chimpanzee, common chimpanzee, robust chimpanzee Chimpanzs (Fr) Chimpanc (Sp). The researchers published their findings Monday (July 19) in the journal Scientific Reports (opens in new tab). The researchers do not know whether or not the second incident in December involved a different group of gorillas. The February encounter lasted 52 minutes, and the gorillas were forced to retreat without their infant. "But then, we heard chest beats, a display characteristic for gorillas, and realized that the chimpanzees had encountered a group of five gorillas." Southern, a doctoral student at Osnabrück University, said in a statement. "At first, we only noticed screams of chimpanzees and thought we were observing a typical encounter between individuals of neighboring chimpanzee communities," first author Lara M. Hergenrother presented the work at last week’s meeting of the Society for Molecular Biology and. The history of the chimpanzee (Pan troglodytes) breeding colony of the Southwest Foundation for Biomedical Research was evaluated over a 24-year period to. The chimps were returning from a territory patrol when the first attack occurred. In various groups of social animals, mating events are sometimes accompanied by acoustically distinct vocal signals, usually produced by the females.1Hauser MD. The chimp mating behaviour does appear to be the derived state, says Jensen-Seaman. The research team was following the chimpanzees responsible for the gorilla killings as part of a long-term study into chimp behavior in Gabon's Loango National Park. Chimps, however, aggressively defend their territories against other chimpanzees and are known to kill members of rival chimp groups. The two ape species typically avoid one another, and even feed on the same fruit trees, without conflict, according to Pika. In addition, they prune and assist in regenerating plant growth, as they choose to eat only green leaves and stalks.Chimpanzees and gorillas normally coexist peacefully where their ranges overlap in the rainforests of Central Africa. Orangutans are important for dispersing seeds, being consumers of a wide variety of fruit, and they also help to maintain the diversity of woody plants of the rainforest. Any adult Great Ape primate has the raw strength to do pretty much anything they want with a human being, and most primate species have been observed demonstrating forcible sexual behavior, including chimpanzees, bonobos, and orangutans. Sumatran orangutans have a big role in the Sumatran lowland rainforests and are therefore considered a keystone species. Even chimpanzee penises are only about 3' in length, and other primates have even shorter penises. Overall, Sumatran orangutans’ numbers are decreasing today and they are classified as critically endangered (CR) on the list of threatened species. In addition, a population that is being established in Jambi and Riau Provinces in the Bukit Tigapuluh National Park, numbers around 70 animals and is reproducing.

Population numberĪccording to the IUCN Red List, the total Sumatran orangutan population is around 7,300 individuals. Recent political instability in the area of their habitat has led to increased illegal logging in areas that are protected, and increased capture of infants to be sold for the illegal pet trade. mating strategies, and dispersal is extensive, and attests to the complexity of chimpanzee behavior and population dynamics. These animals have a unique vulnerability to exploitation due to their extremely long inter-birth period, usually eight years, which makes them the world’s slowest breeding primates.

The primary threat to Sumatran orangutans is loss of habitat.
