At least 88 wolves remain in Yellowstone, but the killings have ¡°been a big hit to us scientifically,¡± says project leader Douglas Smith. Particularly problematic, he says, is that seven of the animals were wearing radio-tracking collars. Two ¡°were the only collared members of their packs, so now we can¡¯t track those packs.¡± Only one wolf wearing a specialized GPS collar is now left in the study. ¹À¼Æ²¶ÁÔÕß±¾ÔÂÒѾÔÚ»ÆÊ¯¹«Ô°É±ËÀÁË10Ö»ÀÇ£¬ÕâÓ°ÏìÁ˼à²â1995ÄêÖØÐÂÒýÈ빫԰ÄÚµÄÀÇȺµÄ¿ÆÑÐÏîÄ¿¡£ÏîÄ¿¸ºÔðÈËDouglas Smith˵£¬Ä¿Ç°¹«Ô°ÄÚÖÁÉÙ»¹ÓÐ88Ö»ÀÇ£¬µ«ÊÇÕâ´Î²¶É±¡°¶ÔÎÒÃǵĿÆÑÐÊÇÒ»¸öÖØ´´¡±¡£Ëû²¹³äµÀ£¬ÓÈÆäÂé·³µÄÊÇÕâ´Î²¶É±µÄÀÇÆ¥ÖÐÓÐ7Ö»´÷×ÅÎÞÏß×·×ÙÏîȦ¡£ÓÐÁ½Ö»¡°ÊÇËüÃÇÄǸö×åȺÖнöÓеĴ÷£¨×·×Ù£©ÏîȦµÄÀÇ£¬ËùÒÔÏÖÔÚÎÒÃÇÎÞ·¨×·×Ùµ½ÕâЩÀÇȺ¡£¡±Ä¿Ç°¸ÃÊÔÑéÖнöÓÐÒ»Ö»´÷ÌØÊâGPSÏîȦµÄÀÇ»¹´æ»î×Å¡£ The killings, which were legal, occurred outside the park during the annual wolf hunting season that opened this fall in Montana, Idaho, and Wyoming. Some researchers fear hunters are targeting collared wolves (Science, 23 October 2009, p. 506), and have asked state officials to establish buffer zones around the park to protect the animals. Only Montana, however, has taken steps to protect wolves in one boundary region.
