Ed Arnett, a conservation scientist with Bat Conservation International, based in Austin, Texas, agrees with Brack that the study is significant but feels that in order to save bats' lives, more focus needs to be placed on understanding the interplay between wind farms and migration paths.

德克萨斯州奥斯汀市蝙蝠保护国际组织的生态保护科学家艾德·阿内特同意布拉克的观点——这项研究很重要。但是，他觉得为了挽救蝙蝠的生命，需要投入更多的注意力，以搞清风电场和和蝙蝠迁徙路线之间的相互影响。

Even in poor countries we can expect low levels of migration if people think that conditions there will improve, argues Brice Quillin, one of the report's authors.
