II. Reading comprehension Part A
Directions: Read the following passages, and choose the correct answers. (30 points)
Passage 1
Conservationists (资源保护者) may get a wrong number of the threatened animals such as elephants, say African and American researchers. The error takes place because of a
,.
weakness in the way they estimate animal number from the piles of dung (粪便) 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 (生物学家) Katy Payne of Cornell University in Ithaca, New York, agrees. “We really need to know elephant number and the evidence (证据) that we have is quite indirect,” says Payne.
Counting elephants from planes is impossible in the vast rainforests of Central Africa, so researchers often estimate elephant number by counting dung piles in a given area. They also need to know the rate at which dung decays (腐化). Because it's quite difficult to decide these rates, however, researchers counting elephants in one region are likely to rely on standard decay rates set up elsewhere.
But researchers at the WCS have found that these decay rates differ from region to region depending on the weather and environment. Using the wrong number can mislead the census (统计), says Plumptre.
He and his colleague Anthony Chifu Nchanji studied decaying elephant dung in the forests of Banyang Wildlife Sanctuary (避难所) in southeast Cameroon. They found that the dung decayed between 55 and 65 percent more slowly than dung in the rainforests of neighboring Gabon. If researchers use decay rates from Gabon to count elephants in Cameroon, they would probably find more elephants than there are actually around.
This could mean estimates in Cameroon are at least twice as high as those got from decay rates calculated locally, says Plumtre. He says that similar problems may also exist in other animal census studies that rely on indirect evidence.
