BEIJING, Kunming, April 7 (Reporter Hu voyage) China Ke Xueyuan Kunming Institute of Zoology 7 news release, recently, the Institute and Zhongshan University, Academia Sinica and other units assembled its first green peacock genome and comprehensive Using a variety of analysis methods to reveal that human interference since prehistoric times is the main driving factor for green peacocks to endangered.
Academy of Sciences The green peacock is known as the "King of Birds".
In order to investigate the main risk factors caused by the process of green peafowl populations recession, and the Keyuan Kunming Institute of Zoology and Zhongshan University, Academia Sinica and other units assembled its first green peacock genome, carried out population genome resequencing, and the integrated use Various analysis methods reveal the rapid decline of the green peacock population since the middle of the Neolithic Age (~6000 years ago).
Zhong ASTRI ASTRI Studies have shown that since the middle of the Neolithic Age, the green peacock population has shrunk by 200 times.
In addition, further statistical analysis shows that historical climate changes have no significant impact on the distribution of green peacocks, while the intensity of human activities has a significant negative correlation with its effective population and current survival status.
The study also revealed that the existing populations of green peacocks have serious inbreeding, and there is an urgent need to strengthen habitat protection and ecological corridor construction to maintain its evolutionary potential to cope with future environmental changes.
Researchers said that biodiversity is currently being lost at an unprecedented rate, and how to carry out biological protection more effectively has become a common issue facing all mankind.
Related research results were recently published in Proceedings of the Royal Society B: Biological Sciences, the flagship publication of the Royal Society.
