BEIJING, Aug. 1 (Xinhua) -- The provinces of Guizhou and Hunan reported their lowest levels of precipitation since 1951 in July, the China Meteorological Administration (CMA) said on Monday.Precipitation levels across the country saw a decrease of 8.7 percent from the average level of 115.9 mm in July, the lowest levels seen in 11 years, said Chen Zhenlin, an expert with the CMA.The average temperature recorded across the country in July was 22.1 degrees Celsius, up 0.7 degrees Celsius from the average level.

PHNOM PENH, Aug. 17 (Xinhua) -- The critically endangered Irrawaddy dolphin population in the Mekong River numbers just 85, World Wildlife Fund (WWF) new research revealed on Wednesday.Calf survival was found to be very low, leading researchers to conclude that the small population is declining and at high risk of extinction, said the Fund's statement sent to Xinhua News Agency on Wednesday.According to Li Lifeng, Director of WWF's Freshwater Program, the research is based on photographic identification of dolphins through individually unique features of their dorsal fins. "Most of the dolphins can be identified, and we use that information to estimate the population size," he said.Although this population estimate is slightly higher than the previous estimate, the researchers were quick to note that the population had not increased over the last few years."With a larger dataset and recent analytical advances, previously unidentifiable dolphins which had few marks on their dorsal fins have been included," he added.However, surveys conducted from 2007 to 2010 show the population slowly declining."Evidence is strong that very few young animals survive to adulthood, as older dolphins die off and are not replaced," he explained."Pressures of gill net entanglement and high calf mortality we are really worried for the future of dolphins," Li said.However, Touch Seang Tana, chairman of Cambodia's Commission for Conversation and Development of the Mekong River Dolphins Eco- tourism Zone, rejected the WWF's finding, saying that last year, 4 dolphins were killed by fishing nets, but up to 7 newborn dolphin babies were found.He estimated that the total population of Mekong dolphins in the north-eastern provinces of Kratie and Stung Treng is between 155 and 177 now, up from just 100 in 2006.The Mekong River Irrawaddy dolphin has been listed as critically endangered on the World Conservation Union Red List of Threatened Species since 2004.

BEIJING, July 15 (Xinhua) -- The Chinese Academy of Agricultural Sciences (CAAS) announced Friday that a group of international scientists has finished sequencing the genetic code of the potato.The Potato Genome Sequencing Consortium (PGSC), which is led by Chinese scientists and made up of 97 researchers from 14 countries, has sequenced the complete potato genome and published a report of its findings in the latest issue of the scientific journal Nature, said the CAAS.The research took six years and revealed that the potato contains about 39,000 genes, said the CAAS.Qu Dongyu, a potato farming specialist with the Crop Science Society of China and a promoter of the PGSC, said the study helped discover genes that define the growth and insect resistance of potatoes.The sequenced genome will enable scientists to create new varieties of potato that are high in yield and quality and more resistant to insects and diseases, he said.Huang Sanwen, a researcher with the CAAS and one of the three corresponding authors of the report, said the sequencing will also allow potato breeders to accelerate the breeding process of new seeds from 10 to 12 years to about 5 years.China is the world's top potato grower, with its farmers planting potatoes on nearly 90 million mu (6 million hectares) of land each year. The average yield per mu stands at 1,000 kg, only one-third of that harvested by countries with advanced technologies, Qu said.

CANBERRA, June 6 (Xinhua) -- Australian beef is not to blame for a recent outbreak of E.coli in Japan, Meat and Livestock Australia confirmed on Monday.Twenty people have fallen ill in Japan's Toyama prefecture, with 15 of them infected with the O157 strain of E.coli after eating at a popular Korean-style barbecue restaurant chain, Gyukaka, on May 6.The operators of the restaurant chain, REINS International, said they suspected the bacterium might have been carried by beef imported from Australia.After conducting an investigation into the Japanese outbreak, regional manager for Meat and Livestock Australia, Melanie Brock, said testing shows Australian beef was not the source of the outbreak."The Toyama prefecture health authorities have confirmed following a thorough inspection that imported Australian beef was not the source of an incident of E.coli," Brock said in a statement on Monday."The authorities continue to investigate other food consumed by the affected customers."Brock said Australian beef has long been recognized by the Japanese trade and consumers for its strong safety record.Brock added that Australian beef for export to Japan is processed under the veterinary supervision of the Australian Quarantine and Inspection Service, and is recognized internationally as bearing a high hygienic standard.
