Conservationists may be miscalculating the numbers
of the threatened animals such as elephants, say African and American
researchers. The error occurs because of a flaw in the way they estimate animal
numbers from the piles of dung the creatures leave behind. The mistake could lead researchers to think that there are twice as many elephants as there really are in some regions, according to Andrew Plumptre of the Wildlife conservation Society (WCS) in New York. Biologist Katy Payne of Cornell University in Ithaca, New York, agrees. "We really need to know elephant numbers and the evidence that we have is quite indirect," says Payne, who electronically tracks elephants. Counting elephants from aeroplanes is impossible in the vast, equatorial rainforests of Central Africa. So researchers often estimate elephant numbers by counting dung piles in A. "endangered" B. "frightened" C. "died" D. "angered" [判断题]定量投资对信息管理提出的要求反而更多地体现在定性的信息,而定性投资则需要更多定量的信息。
