在美国南达科他州风洞国家公园，土狼（Canis latranans）的活动范围大小和种群丰度指数尚未被记录。在2003年和2004年，我们共捕获了26只土狼，并给22只成年土狼（12英尺，10米）戴上了放射性项圈。2003年和2004年，17只土狼中有2只（12%）和9只土狼中有5只（56%）在捕获时感染了疥螨（疥螨）。因此，目标被修改为记录管理兽疫对土狼种群的影响。2003年，有管理的配偶土狼和被认为健康的配偶土狼的家园范围（适应内核）大小分别为8.26 +/- 1.63 (SE) km(2)和9.67 +/- 2.80 km(2)。2004年有管理和无管理的雄性土狼的活动范围分别为22.69 +/- 9.06 km(2)和12.51 +/- 2.73 km(2)。男性的家范围大小在年龄（P = 0.14）或状态（有或没有管理，P = 0.84）之间没有差异。2003年底，戴项圈的土狼的存活率为60%。粪线样条的相对丰度指数表明，2003 - 2004年，土狼的数量减少了48%。持续监测虫性管理动物流行病将使管理人员能够评估管理对土狼种群的影响。
Home-range size and population abundance indices of coyotes (Canis latrans) have not been documented in Wind Cave National Park, South Dakota, USA. In 2003 and 2004, we captured a total of 26 coyotes and radiocollared 22 adults (12 F, 10 M). In 2003 and 2004, 2 of 17 (12%) and 5 of 9 (56%) coyotes, respectively, were infected with sarcoptic mange (Sarcoptes scabiei) at the time of capture. Thus, objectives were modified to document effects of the mange epizootic on the coyote population. In 2003, home-range (adaptive-kernel) sizes for mate coyotes with mange and those considered healthy were 8.26 +/- 1.63 (SE) km(2) and 9.67 +/- 2.80 km(2), respectively. In 2004, home-range sizes for those male coyotes with and without mange were 22.69 +/- 9.06 km(2) and 12.51 +/- 2.73 km(2), respectively. Male home-range size did not differ berween years (P = 0.14) or by status (with or without mange; P = 0.84). Survival of collared coyotes was 60% at the end of 2003. Results from fecal line transects, an index of relative abundance, indicated that the coyote population decreased by 48% from 2003 to 2004. Continued monitoring of sarcoptic mange epizootics will enable managers to assess the effects of mange on coyote populations.
