WASHINGTON,moncler, Dec. 11 (Xinhua) -- Female elephants living in protected populations in Africa and Asia live longer than those in captivity in European zoos,abercrombie, an international team of researchers reported Thursday in the journal Science.
The findings could mark the end of a long-standing debate about the physical and mental well-being of zoo elephants and may also bring about improvements in how these animals are kept,burberry pas cher, the researchers said.
Using data on more than 4,abercrombie and fitch,500 elephants,moncler pas cher, researchers from Britain,doudouen moncler, Kenya and Canada found that zoos can cause shortened adult life spans in both African and Asian elephants.
