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.

BEIJING, March 10 (Xinhua) -- The Chinese government will adopt stricter measures to boost energy conservation this year to meet the goal set by an important five-year plan, Xie Zhenhua, vice minister of the National Development and Reform Commission, said Wednesday."It's the last and decisive year for us to realize the goals set by our country's 11th Five-Year Plan," Xie said at a press conference on the sidelines of the annual session of the National People's Congress, China's top legislature."The current energy conservation situation lags far behind the goal set in our plan and our task is still formidable," said Xie, one of China's leading negotiators for climate change talks.Under the 11th Five-Year Plan ending this year, China pledged to cut energy consumption per unit of gross domestic product (GDP) by 20 percent, or four percent each year, but consumption fell by a margin much smaller than the set target during the past four years.The per unit GDP energy consumption fell only 14.38 percent from the 2005 level.Xie said the Chinese government will enact a series of measures this year to boost energy conservation, including the introduction of an accountability mechanism for provincial governments and tight control of projects of high energy consumption and high pollution.China announced in November it aimed to reduce the intensity of carbon dioxide emissions per unit of GDP in 2020 by 40 to 45 percent compared with 2005 levels.

  

BEIJING, March 20 (Xinhua) -- The threat of inflation to China's economy is less worrisome compared with asset bubble, economists said Saturday at the China Development Forum 2010.China's economy is facing a new round of growth in the coming two years, but the risks of inflation and asset bubble remain, said Fan Gang, secretary general of the China Reform Foundation.Compared with inflation, tackling asset bubble is of greater importance because asset bubble, as one of the causes for this round of global financial crisis, is more dangerous, Fan said. He expected the country's economy to grow 8 to 9 percent this year in a "normal growth."Growth in China's property prices is accelerating and approaching an alarming level, said Nomura Holdings Inc. chairman Junichi Ujiie.Despite government measures to curb property prices, China's property market grew at its fastest pace in 20 months in February, with housing prices in 70 major cities rising 10.7 percent from a year ago.

  

BEIJING, Feb. 2 (Xinhua) -- China has dispatched inspectors to 16 provinces to urge local authorities to thoroughly investigate cases concerning food safety, the government's latest move against a string of reportedly resurfacing melamine-tainted milk products after a nationwide crackdown in 2008.Any law-breaking concerning food safety will be severely dealt with, an official with the National Food Safety Rectification Office led by Health Minister Chen Zhu said here Tuesday.The unnamed official said the office recently dispatched eight teams of inspectors. The official did not give details on the total number of inspectors involved or their identities.Milk powder laced with melamine that should have been destroyed has been used, local authorities discovered.Media reports said melamine-tainted dairy products have resurfaced in several Chinese provinces.Melamine is an industrial compound which can give a false positive on protein tests and cause kidney stones. Melamine-contaminated milk products left at least six children dead and 300,000 sickened in 2008."These cases reveal that the toxic milk powder recalled in 2008 was not completely destroyed and is now illegally reused for new products," the official said.In December 2009, three people from the Shanghai Panda Dairy Company were prosecuted on suspicion of producing and selling melamine-tainted milk powder. Local police said all the company's products had been recalled and that there was no harm to consumers.Another three people from the Shaanxi Jinqiao Dairy Co. Ltd. in northwest Shaanxi Province had also been detained by police over suspected tainted milk powder sales before its products reached retail stores.Food safety issues have became particularly sensitive in China after the 2008 milk scandal. The government has intensified supervision of food safety with new laws and regulations, including the Food Safety Law that took effect on June 1, 2009. Nationwide checks of food safety have also been increased.The official said food safety was a global issue, one that existed in both developing and developed countries.Improving food safety standards is a long-term tough task for China, the official added.
