摘要
2006年9月21日至10月21日、2007年1月14~20日、2月6~12日和3月13日至4月8日,应用无线电追踪技术对青海省都兰县沟里乡3只藏狐(2雄,1雌)进行追踪定位,采用Kernel方法计算了3只藏狐的家域面积,确定了该物种的核域,并探讨了不同藏狐个体间家域及核域的重叠状况。结果表明,沟里乡藏狐平均家域面积为6.4±0.4km^2,平均核域面积为1.6±0.2km^2,核域约占家域总面积的1/5~1/4。3只藏狐总体家域面积相差不大,藏狐家域及核域均有一定程度的重叠,家域重叠程度约为50%~60%,核域重叠程度则远远减小,约为7%~20%。
We documented home ranges for 3 radio-marked (2 ♂ , 1 ♀ ) Tibetan foxes (Vulpesferrilata) in Gouli township, Dulan County, Qinghai Province, China in Sep. 21 - Oct. 21, 2006 and Jan. 14 - Jan. 20, Feb. 6 - Feb. 12 and Mar. 13 - Apr. 8, 2007. Home ranges of 3 collared Tibetan foxes were quantified using the fixed kernel method, and a simple index of home range overlap was also calculated. Mean home range size was 6. 4 km^2 ( SE = 0. 4) and the mean core area was 1.6 km^2 ( SE = 0. 2). Home ranges and core area of all 3 foxes overlapped. Percentage home range overlap was 50% -60%, and overlap of core areas was 7% -20%.
