In this study, we estimated takin seasonal and annual home range size and its fidelity between years by utilizing 9 GPS radio collars on adult takin(2006-2009). Results shown annual home range of takin was (MCP/FKE)(15.01±2.92)km2 /(9.02±1.85) km2, suggesting individual home range varied among individuals and years. For each individual, we found variation of seasonal home range between years. Most of individuals shown similar pattern of seasonal home range variation, thus the largest home range always found in summer or spring. We extracted the centriods of seasonal / annual home range polygon and calculate its distance between years. We tried the distance between two centriods as one surrogate of home range fidelity. Besides, we considered the overlap ratio of home range between two consecutive years as the most important parameter of home range fidelity.Therefore, we found annual home range fidelity of certain season variation exist, especially for summer and autumn. Both ways of home range fidelity assessment produced similar results. 参考文献 相似文献 引证文献
