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 8 (Xinhua) -- The recent number of earthquakes above 7-magnitude in 2010, though slightly more than average, was still within normal scope, said the China Earthquake Administration Monday.The administration cited that the frequency of the quakes were uneven. "It is a normal phenomenan of earth movement," it said.Some panicked netizens linked the recent spate of earthquakes to Doomsday Day as depicted by Hollywood disaster film "2012" shown in 2009.China is an earthquake-prone country, witnessing a total of 145 quakes on average on the mainland each year, with 20 quakes above 5 magnitude.

BEIJING, Jan. 31 (Xinhua) -- The Chinese mainland announced Sunday it would extend anti-dumping measures by five years on imports of phenol from Japan, the Republic of Korea, the United States and Taiwan.The Ministry of Commerce (MOC) said in a statement posted on its website that it decided to review the measures a year ago in response to applications from domestic phenol companies.According to the MOC, if anti-dumping measures were discontinued, dumping of phenol might continue and would hurt the domestic industry again.However, the MOC did not provide further information concerning what the measures were and when they would take effect.Phenol is a chemical compound used in the production of some medicines, plastics, pesticides and synthetic resins.

BEIJING, March 8 (Xinhua) -- China is making plans to upgrade its food safety system, stressing improved quality standards and strengthened supervision, according to a notice made public Monday at www.gov.cn.In late February, south China's Hainan Province took emergency measures to stop toxic cow peas from entering the market after about 3.5 tonnes of Hainan cow peas found were tainted with a poisonous pesticide.To prevent such incidents and help ensure food safety, the country plans to increase the frequency of food tests and inspections -- especially for dairy products and other high-risk food.National quality standards for diary products will also be released this year.At least six infants died and almost 300,000 became ill across the country after consuming dairy products tainted with the industrial chemical melamine. The scandal was first reported in September 2008 and prompted a food safety overhaul nationwide.
