Conservationists have believed that by concentrating their preservation efforts on habitats rich in an easily surveyed group of species, such as birds, they would thereby be preserving areas rich in overall species diversity. This belief rests on a view that a geographical area rich in one group of species will also be rich in the other group’s characteristic of the entire regional climate zone. Which of the following findings about widely scattered tracts 10 kilometers by 10 kilometers in a temperate climate zone would most seriously challenge the conservationists’ assumptions?
选项
A、The tracts show little damage from human intrusion and from pollution by human activities.
B、Where a certain group of species, such as birds, is abundant, there is also an abundance of the species, such as insects, on which that group of species feeds, or in the case of plants, of the land and water resources it requires.
C、The area of one of the tracts is generally large enough to contain a representative sample of the organisms in the region.
D、There is little overlap between the list of tracts that are rich in species of butterflies and the list of those that are rich in species of birds.
E、The highest concentration of individuals of rare species is found where the general diversity of species is greatest.
答案
D
解析
本题是要找一个选项对Conservationists assumption进行反对,即找一个选项说明富有一个物种的地区可能不会富有其他同气候区的物种。(D)选项指出在蝴蝶种类较多的地方,鸟类的种类不一定多,从而指出了Conservationists assumption的错误,所以(D)为正确答案。
