Into the wild 答案 P575 (2021·山东省临沂市高三期中) Conservationists have long known that using pandas, tigers and other charismatic (有号召力的) species to front their campaigns is a good way to raise money. But some people argue that focusing on these “ flagship” animals can ignore equally threatened but less cute ones. Now Jennifer McGowan at Macquarie Uni- versity in Sydney and her colleagues suggest that we can have it both ways after finding that fun- ding for flagship species also helps other threat- ened species in the surrounding areas. McGowan􀆳s team first drew up a list of 534 flagship species in wildlife-rich hot spots around the world. The biodiversity areas were each split into grids (网 格) of 100 by 100 kilometre squares. The re- searchers then compared two conservation approa- ches across eight simulated scenarios (模拟场景) which assumed different levels of human activity and protected areas. The first focused on protecting flagship spe- cies, while the second aimed to protect the maxi- mum number of species in an area, regardless of their fundraising potential. Their study has found that targeting grid squares with flagship species also protected 79 to 89 per cent of the non-flag- ship species in that area. The figure rose to 97 per cent in some scenarios. “The findings could help when choosing which species to promote. Flag- ship species are very effective at getting the public to care,” she says. Morgan Trimble, the author of a paper that has found scientists also have a bias towards charismatic animals, says
