Recently, the British journal Nature Ecology and Evolution published an ecological study on the 11th, a deer with ungulates that is scientifically considered to have disappeared, was rediscovered in the Vietnamese wild, and the last time information about this species was heard was in 1990, when this silver-backed shrew deer was hunted and made into a specimen, after 30 years, researchers photographed a live silver-backed shrew deer for the first time.
Living in the Great An nam Ecoregion of Vietnam and Laos, where the world's most biodiversity is most pronounced, in 1910, following samples taken near Nha Trang in Vietnam, the silver-backed shrew deer was given a name for the species, the silver-backed shrew deer, which for a long time was not witnessed by humans, and it was once thought that large-scale local trap hunting may have pushed the species to the brink of extinction.
World Wildlife Conservation Society scientist Ann Nguyen and colleagues interviewed local residents to confirm sightings consistent with the description of the silver-backed weasels, trying to locate the species, after which they placed more than 30 traps in the nearby forest based on the information they obtained, and in the next 6 months, the researchers found more than 200 silverback shrews, but their populations are still unknown.
Although scientifically, the species is seen as "rediscovered" after disappearing, the local population does not believe that they have ever been extinct, and scientists believe that more intensive investigations and closer communication with the local population are needed to determine the population size of the species and ensure that the species can be more protected.
Strictly speaking, extinct species refers to species that have not been identified in the wild in the past 50 years, and the silverback shrew deer has disappeared in the past 30 years and is now reappearing, probably because the researchers' search scope has expanded, and there is also a good signal that the population is slowly recovering, and scientists have found that the silverback shrew deer does not mean that it is farther from extinction, after all, the population is the key, and when its existing number is not enough to maintain the population development, the wild extinction is still its fate, The best way to do this today is to preserve its population DNA and protect its habitat.
The silver-backed shrew deer is a subspecies of the weasel deer, there are 38 subspecies of the shrew deer, about the same size as the hare, weighing 125-210g, 42-60 cm long, shoulder height of more than 20 cm, is the smallest ungulate after the members of the ungulate rabbit order, and is also the smallest of the shrew deer family. The face is pointed and long, both male and female have no horns, and the male has developed fangs. It is mainly distributed in the Indochina Peninsula in Asia and the islands of Java and Sumatra in Indonesia.
The weasel is a rare species between the camel family and the deer family, and is the smallest ungulate on Earth, with the shape of a pocket version of the red deer. Because it maintains many of the original characteristics of deer, it has high scientific research value. They are also one of the oldest and most primitive species of existing ruminant ungulates. A small number of wild populations of shrew deer are distributed in the Xishuangbanna area of Yunnan, China, and the current population in China is only about 1300, which is a national first-class protected animal.
Let's protect these rare wildlife and maintain the diversity of species.
