CHANGSHA/HARBIN, Feb. 12 (Xinhua) -- As Chinese people are embracing the arrival of the Year of Tiger on Saturday, zoologists are worried about the survival of South China Tigers as the endangered species are facing a serious problem of inbreeding.No traces of the tigers have been found in the last decade, they said.The number of captive South China tigers (Panthera tigris amoyenesis) rose to 92 in 2009 from 60 in 2007 but all the tigers were the offsprings of six wild South China tigers which were caught more than 40 years ago, said Deng Xuejian, a professor with the Department of Biology of Hunan Normal University, based in Changsha, capital of central China's Hunan Province."The inbreeding may lead to genetic freaks, low survival rates and poor physical makeup," Deng said.All the genes have come from two male and four female tigers, which had lead to highly identical genes in the offspring, Deng said."The situation may reduce the genetic diversity and cause degradation or even the extinction of the species," he said.The tigers would lose genetic diversity if their genes were too similar, said Ma Zaiyu, president of veterinary hospital of Changsha Zoo."The number of the members of a species should be at least 1,000 to maintain the stability of the species," Ma said.Zoologists estimated the number of wild South China tigers could have been less than 30 in the 1990s. The remaining wild tigers are presumed to live in the remote areas of Guangdong, Hunan, Fujian and Jiangxi provinces, Deng Xuejian said.Based on analysis of relevant date combining field investigation, Deng estimated the number of wild South China tigers could be less than 10.No traces of wild South China tigers were reported in Hunan in the last two years, said Zhou Shuhuai, director of wildlife protection section of the Hunan provincial forestry bureau."The number is limited and the tigers scatter in different areas, which make it difficult for natural breeding between wild tigers," said Huang Gongqing, a tiger expert at South China Tiger Breeding Base in Suzhou, a city of east China's Jiangsu Province."The extinction of the wild tigers will happen sooner or later," Huang warned.Some experts have said that there may be already no wild South China tigers. "However, we cannot know as the animal is very difficult to trace," Deng said.Ma Zaiyu said to avoid extinction of the species, more captive tigers should be bred, and some genes might be recovered when the population reaches 1,000, while Deng suggested continuous search for wild tigers to enrich the captive tigers' genes.The situation is much better for the Siberian tigers (panthera tigris altaica) in northeast China as the number of the wild ones is quite stable, experts said.The number maintains at around 20 in China, among which 10 to 14 are in Heilongjiang Province and eight to ten are in Jilin Province, said Sun Haiyi, deputy director of Heilongjiang Wildlife Institute"But no more young tigers under one year old have been discovered in the past two years. The reason might be the number of female tigers are less than the males and the animals are relatively isolated by the mountains," Sun said.China established a breeding base for the Siberian tigers in Heilongjiang in 1986 and the number of captive tigers has increased from eight to current more than 800, Sun said.Experts called for more efforts to protect the habitats of the tigers for the purpose of protection and re-wilding of the tigers.

PARIS, March 8 (Xinhua) -- Nuclear power should be developed with due regulations and in an orderly way thanks to its strict requirement for human resources, technology, security and quality, a Chinese official said Monday here at the international conference on civilian use of nuclear energy.Nuclear power, a clean, safe and economic energy, "plays an important role in energy conservation, environment protection and the strive to cope with climate change," Deputy Director of China' s National Energy Administration Wu Yin said, adding it has became "a major choice to develop economy and optimize energy structure" for many developing countries.Speaking to representatives from about 60 countries at the headquarters of the Organization of Economic Cooperation and Development, Wu said that changing the mode of energy development, optimizing the energy mix and reducing carbon emission is now a shared aspiration of the world.According to him, China has accelerated the construction of nuclear power stations in recent years. Besides 11 nuclear power units that are already in operation, there are 21 many units under construction with a combined installed capacity of 23 gigawatts.Taking the nuclear security as the top priority, Wu presented some suggestions addressing the increasing global demand of nuclear access."The security of nuclear energy is beyond borders, we should strive to shape a culture on safe use of nuclear power. Developed countries in terms of nuclear use have the responsibility to help the less developed ones to establish laws and regulations, supervision and management systems on nuclear security," Wu said.On proper use of nuclear power, Wu said countries must take national conditions into consideration, enhance international cooperation to make nuclear power safer and cheaper.China would make "responsible efforts to develop nuclear energy in order to protect the environment, to cope with climate change and to promote sustainable development," Wu said.Hundreds of ministers, government officials and business leaders convened in Paris for the two-day conference on access to nuclear energy, which is initiated by France and co-organized by the International Atomic Energy Agency and OECD.

  

BEIJING, March 3 (Xinhua) -- Lawmakers from ethnic minorities in northwestern China's Qinghai Province on Wednesday urged for more favorable policies for the minority groups with small population, or the groups each with a population of less than 100,000."I hope the country will provide more support for industries with ethnic features in the the formulation of the 12th Five-Year Plan (2011-2015)," said Han Yongdong, who is also head of Qinghai's Xunhua Salar Autonomous County government."We also need more support for education and employment. Those policies would help the small ethnic groups cultivate an independent 'blood-making' capability to sustain their own development," said Han from Salar, one of China's 22 ethnic groups with small population.Compared with the country's booming coastal regions, regions where ethnic groups with small population live, mostly in central and western inland regions, remain relatively backward.To accelerate the development of the regions where ethnic groups with small population live, China's State Council passed in 2005 a guideline, promising to build roads, schools and basic medical institutions, and provide them with access to electricity, TV and phone service, and drinking water, in addition to sufficient farms and pastures to live on.According to statistics from the State Ethnic Affairs Commission, China had invested more than 2.5 billion yuan (about 368 million U.S. dollars) in 8,065 projects aimed to support small ethnic groups between 2005 and November 2009.But for Qiao Zhengxiao, another deputy to the NPC and Party chief of the Qinghai University, the aid to ethnic minority groups was still not enough."The central government mainly focused on Tibet and other regions of ethnic groups with relatively larger population last year and this year," said Qiao, from the Tu ethnic group."I hope the government will attach more importance to ethnic groups with smaller population in the future," he said.He suggested ethnic minority groups each with population less than 300,000 be covered by the favorable polices passed in 2005.Meanwhile, Han Yongdong also suggested that museums and research projects should be set up to protect the small ethnic groups' culture."My own kid cannot speak the Salar language. It would be too late if we don't start soon," he said.
