The person who discovered it was a … Central circus actor. This person found mutant orchids on a village banyan tree. At that time the flowers were blooming. They share with local people and also bring them to plant. Later, that orchid was named “Phu Tho white five-pointed”. Prof. Tran Duy Quy – Former Director of the Institute of Agricultural Genetics, Chairman of Hanoi Orchid Association analyzed the mutant orchid Those who study deeply about orchids divide mutant orchids into 2 main types according to the flower face: The first is the white five-pointed flower, the second is the pink five-pointed flower. In the five white wings again divided many criteria. The best criteria of a mutant flower must have the structure of 3 sepals and it must be balanced, not too big, not too small, the arrangement position must be balanced. There are species of wings like the swallow or a crane called “fake crane”. There are types of horizontal shoulder blades (orchid players like the one that is horizontal to gourd), petals, sepals white as jade and wax, when shooting light up like a meteor. Throat of flowers must not be smudged, multicolored, must be clean and have a uniform color … Mutant orchids are analyzed by orchid players according to the characteristics and criteria to evaluate beautiful orchids A beautiful flower must have all the criteria: The flower structure must be balanced, the petals and sepals are in balance, not too big, too small, smooth lips like snow, clean throat, clear hydrolyzed nose, aroma. seductive. If all of these criteria are met, they will be graded as the highest cotton, if lacking, then downgrade. Why spread expensive mutations? Professor Quy answered: Firstly, it is rare, millions of new trees have one mutant tree. Plants have less vitality than other types, with a healthy vitality type, the cotton face is not beautiful. Mutant orchids can only clone naturally to retain the shape, structure of the plant and the floral structure of the mother plant. If the nucleus implants tissue, it is, in principle, impossible to multiply. Because too many growth regulators are used, the plants at flowering are deformed. How to recognize mutant spread? Professor Tran Duy Quy affirmed, playing mutant orchids or playing normal orchids must have knowledge of farming. The orchid player must know to meet the 4 requirements of care: First, orchids like moisture but not too much water, like sunlight but not direct sunlight, like the wind but not too strong wind, like the temperature but must not be below 5 degrees and not higher than 42 degrees. Ensuring those four conditions to play spread. Mutant orchids must be balanced Second, want to distinguish an ordinary flower plant from a mutant orchid, in addition to distinguishing morphology of the leaf stems, it is imperative to have blooming flowers to distinguish. “The most famous morphological taxonomists in the world without flowers would dare not identify the scientific name, let alone normal players,” Quy warned. According to Professor Quy, orchids mutate from blooming to dying, lasting from a few weeks to a month, depending on the species. The flower player only keeps the flower at its best, then cuts it off to preserve the tree. If you play flowers until they fall, the flowers will take all the nutrients of the mother plant, which is very difficult to recover. Why there are several hundred billion orchid pots, Mr. Quy said, because it is the top, rare, beautiful type and other reason is the size of the orchid pot. “For example,” Peking Beauty “tree, 1 kie costs 5 billion. For a 2m tall tree, you can make 50 kie, each 4cm long, multiply by 5 billion to get 250 billion. So, seeing people say that the pot is a few hundred billion dong, you have to hear that the pot is short or thick, many bodies or less, ”explained Professor Tran Duy Quy. In the 5-pointed white-winged mutant orchid, it is divided into the popular, medium, medium, high, high, and special types. The popular type has 5 Phu Tho white wings, 5 HO white wings, 5 Ha Tinh white wings, 5 deer-eyed white wings, 5 Lac Long Quan white wings, 5 Da Bac white wings, 5 Nghe An white wings, 5 Lam white wings marine. The more upscale part has Snow White, Plây-ku Eyes, Beauty of Binh Duong, Grasslands, Anonymous Beauty … High-end orchids Juliet, Ngoc Son, Vinh Khang, Great Butterfly. In particular, the top of the table is now the “Long Khanh Beauty” orchid that costs up to 40 billion VND / cm.

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 beating 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 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 pound their breasts more often during oestrus in female gorillas, so the sound of the chest beats can be an important physical 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 government 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 the local community, spreading propaganda through materials and books and teaching students about biodiversity and protecting this endangered animal.

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.
