![]() During these patrols, chimpanzees travel to the periphery of the territory to search for signs of members of other communities or may even make deep incursions into neighbouring communities involving lethal coalitionary attacks 13, 14, 15, 15. The majority of killings involve intercommunity rather than intracommunity attacks, and most often are made by coalitions of males during territorial boundary patrols 5, 13. Rates of intraspecific killings vary considerably among chimpanzee communities, with adult males being both the main attackers and the main victims 11. However, it is nearly absent in bonobos ( Pan paniscus) (but see 11) and orangutans ( Pongo ssp.) 12. Similar content being viewed by othersĬoncerning our closest living relatives, the great apes, intraspecific killing has frequently been reported across multiple chimpanzee ( Pan troglodytes) communities e.g., 5, 6, 7 and gorilla ( Gorilla gorilla) 8, 9, 10 groups. In addition, they may aid in combining field data from extant models with the Pliocene hominid fossil record to better understand behavioural adaptations and interspecific killing in the hominin lineage. Our findings may spur further research into the complexity of interspecies interactions. Given these events meet conditions proposed to trigger coalitional killing of neighbours in chimpanzees, we also discuss them in light of chimpanzees’ intraspecific interactions and territorial nature. We discuss these observations in light of the two most widely accepted theoretical explanations for interspecific lethal violence, predation and competition, and combinations of the two-intraguild predation and interspecific killing. In both events, the chimpanzees significantly outnumbered the gorillas and victims were infant gorillas. ![]() Here, we provide the first information of two lethal coalitionary attacks of chimpanzees ( Pan troglodytes troglodytes) on another hominid species, western lowland gorillas ( Gorilla gorilla gorilla), that occur sympatrically in the Loango National Park in Gabon. ![]() Contrarily, interspecies violence has mainly been investigated in the context of predation and received most research attention in carnivores. "We found extensive dirt, chimp fur, and chimp teeth implanted in her bone.Intraspecies violence, including lethal interactions, is a relatively common phenomenon in mammals. "The monkey had ripped off her entire upper jaw, had ripped off her nose, which as hanging by a thread," said Dr.Kevin Miller, who treated Nash when she taken to the emergency room. Paramedics responding to a 911 call said they found pieces of Nash's fingers strewn on the floor and her hands looked as though they had been through a meat grinder. Nash was mauled by a 200-pound adult chimpanzee named Travis, owned by her friend and employer Sandra Herold. "I don't think about it Theres no time for that because I need to heal, you know, not look backwards." There are things that happen in life you can't change," she said. ![]() She said she felt no pain, was not angry and was ready to move on with her life rather than dwell on that horrific day. Nash, 56, must drink all of her meals with a straw though a small hole where her mouth used to be, She said she longs for the day when she might be able to eat "a hot dog or piece of pizza."Ĭlick here to see Charla Nash's uncovered faceĭespite her injuries, Nash seemed remarkably upbeat. I know that I have my forehead," she told Winfrey. "I don't ask a whole lot about my injuries. 11, 2009— - The Connecticut woman who was attacked by her friend's chimpanzee in February, revealed the mangled remains of her face on the Oprah Winfrey show today for the first time, publicly showing the remnants of her missing eyes, nose and lips.Ĭharla Nash, who wakes up every day in a hospital room at the Cleveland clinic where doctors change her bandages daily, told Winfrey she rarely touches her face so as not to learn the full extent of her injuries. ![]()
