Now, the wild mountain gorilla (Gorilla beringei beringei) in Rwanda’s Volcanoes National Park has “confessed” to the scientists secretly beating their breasts. The research has been published in the journal Scientific Reports under Nature and led by Dr. Edward Wright of the Max Planck Institute of Evolutionary Anthropology in Germany. The mountain gorilla (Gorilla beringei beringei) is one of two eastern gorilla subspecies, comprising two populations. A population found in the Virunga volcano in Central Africa belongs to three national parks: Mgahinga, in southwestern Uganda; Volcanoes, in northwestern Rwanda; and Virunga in the eastern Democratic Republic of the Congo. The remainder was found in Bwindi Prohibited National Park in Uganda. Some primateists consider the Bwindi population a separate subspecies, although no complete description has been made. As of November 2012, an estimated total population of mountain gorillas was 880 individuals. From January 2014 to July 2016, researchers observed 25 wild male silver-backed gorillas overseen by the Dian Fossey Gorilla Fund International (Dian Fossey Gorilla Fund International), and recorded more. 500 chest beats. They recorded the chest pounding sounds of six of the gorillas, measured the rhythm and duration of each gorilla’s chest beat, and the frequency of the chest beating sounds. At the same time, they used the photographs to measure the shoulder widths of these gorillas to determine the sizes of different gorillas. Mountain gorilla. Mountain gorillas are descendants of monkeys and ancient apes found in Africa and Arab in the early Oligocene (34-24 million years ago). The fossil where the mountain gorilla lives is poor and its evolutionary history is unclear. About 9 million years ago, a group of primates evolved into gorillas, separated from their common ancestors with humans and chimpanzees; This is when genus Gorilla comes in. The mountain gorilla split from the eastern delta gorilla about 400,000 years ago and the two subspecies split from the eastern gorilla about 2 million years ago. There is much unresolved debate about the classification of mountain gorillas. The genus Gorilla was originally named Troglodytes in 1847, then renamed as it is today in 1852. By 1967 taxonomist Colin Groves proposed that all Gorilla genus consisted of only one species (Gorilla gorilla) with three Subspecies Gorilla gorilla gorilla (western plains gorilla), Gorilla gorilla graueri (delta gorilla found in western Virungas) and Gorilla gorilla beringei (mountain gorilla). In 2003, after review, gorillas were divided into two species (Gorilla gorilla and Gorilla beringei) by the International Union for Conservation of Nature (IUCN). After analyzing these measurement data, they found that “mountain gorillas can reliably transmit body shape information by beating their chest”. Specifically, large males will emit a lower frequency sound when they strike the chest. Researchers speculate that this may be related to their body’s large resonance cavity. Researchers also found that males beat their breasts more often during oestrus in female gorillas, so the sound of the chest beats could be an important body manifestation during flirting, a on the one hand, attracting children, and on the other hand, frightening the opponents. Interestingly, the beats and timing of these gorillas have nothing to do with body size, and not that the larger the size, the longer the beat. The chest beat of each gorilla is like a behavior showing the different personality, duration and frequency that will carry the characteristics of each individual. Researchers have analyzed that personalized beats could allow other gorillas to distinguish who was beating their chest from them. Mountain gorillas have been reported to have led to a threat of extinction due to poaching – mountain gorillas are often permanently injured by traps. hunt wild animals or take young individuals to zoos. Occupation – the rapid expansion of people’s settlements around the park’s safety corridor. Disease – mountain gorillas are regularly in contact with tour groups from all over the world, they can completely infect human infections. War, political turmoil – refugees flock to mountainous areas, cut trees and hunt gorillas for their meat for temporary life. Because of the above reasons, the World Animal Protection Organization and the host country authorities have increased patrols, using armed soldiers to remove traps, in addition to the work of determining the number of Gorillas mountain remaining. Expand the area of ​​the national park, require tour groups to stand away from monkeys, better manage this type of ecotourism. Another important part is educating local communities, spreading propaganda through materials and books and teaching students about biodiversity and protecting endangered animals. Ultimately, the scientists concluded that mountain gorillas live in dense rainforests, and sometimes they cannot see each other even when very close, but throbbing conveys personal information. it’s important for them to communicate.

Chest patting is a means of communication However, recently a new study has revealed that gorilla clapping behavior is not quite as we know it. Research published in the journal Scientific Reports concluded that gorilla clapping was in fact a means of non-verbal communication that “encoded” their competitiveness instead of boasting of strength. The gorilla clapping itself represents an interesting kind of communication unlike a human. It is not really a voice but an act of inclination to show off visible and audible physical strength. To draw conclusions, the researchers sought to record the sound of the chest beating using photometry. With this method, scientists do not need to get close to the gorilla because the extremely powerful male monkeys pose many dangers in Volcanoes National Park, Rwanda. However, even using photometry, scientists still need to be in the right place and at the right time to catch chest beats from gorillas. The results showed that sounds had lower frequencies in large male mountain gorillas, while younger males had higher frequency sounds. Where low-frequency sounds travel further than high-frequency sounds, which means that larger males can be more formidable competitors. This is useful for males of similar or smaller size who can use the information to decide if it is worthwhile against the competitor or to step back. In previous research conducted by the same group of researchers found that the larger male mountain gorillas not only were socially dominant, they were also more likely to reproduce successfully than the offspring. the male is smaller. With female monkeys, they will also collect information from the male monkey’s chest pounding sound to decide on a worthy mate. “The gorilla’s chest banging is one of the iconic sounds of the animal kingdom, so it’s great that we can prove that gorilla’s body size has been encoded in the displays. This spectacular performance, “said Edward Wright, author of the study from the Planck Institute of Evolutionary Anthropology. Critically endangered species on the Red List Gorilla is a genus of primates belonging to the family of humans, herbivores living in the jungles of Africa, the largest of the extant primates. Gorillas are divided into two species (there can be 4 to 5 more subspecies). The DNA of the gorilla is the same as that of humans 98% -99%. They are very closely related to humans after only 2 species of chimpanzees. This primate has a massive body. Gorillas are 1.7–2 m tall when standing upright and weigh 180–200 kg. These animals usually walk on all fours, although they can stand on two legs. Gorilla lives in the tropical and subtropical forests of Africa. Gorillas move with their knuckles, although they can sometimes stand upright with food or on defense. Wild adult gorillas weigh 135 to 180 kg (298 to 397 lb) while females are usually half as much as 68–113 kg (150–249 lb) males. Adult males are 1.7 to 1.8 m (5.6 to 5.9 ft) tall, with an arm span of 2.3 to 2.6 m (7.5 to 8.5 ft). Females have a shorter arm span. The adult male gorilla is known as the “silver back” due to the silver hair on its back. Occasionally, a silverback greater than 1.8 meters and 230 kg is recorded in the wild. The obese gorilla in captivity 270 kg. Gorillas live in groups under the command of the strongest and most powerful male. It is the male’s duty to lead and protect the whole herd from being attacked by wild animals. The gorilla’s most dangerous enemy is the very ferocious leopard. When threatened, the male will stand upright and pound his stomach with two hands to warn him before fighting. The gorilla is known as a powerful beast with a large appearance, much stronger than a human, powerful and intelligent hands and a gorilla punch that can make everything facing a deformation. . Despite its massive and massive body, Gorilla has an average running speed of about 40 km / h. All species (and subspecies) of the gorilla are listed as Critically Endangered on the IUCN Red List. Now, more than 100,000 western lowland gorillas are thought to exist in the wild, with 4,000 in zoos; The eastern lowland gorilla has a population of less than 5,000 in the wild and 24 in the zoo. The mountain gorilla is the most endangered species, with an estimated population of 880 remaining in the wild and no species in the zoo.
