Accurate estimates of a primate's home range are important, yet methods vary greatly. This paper examines the accuracy of minimum convex polygon (MCP), adaptive kernel (AK) and fixed kernel (FK) estimators by comparing home range estimates of northern bearded saki monkeys (Chiropotes satanas chiropotes) living in forest fragments and continuous forest in the Brazilian Amazon area. MCP was more accurate than AK and FK in calculating home and day range when sample size was small, and AK overestimated range most frequently. It is important to consider the various home range methods, as the appropriate method may depend on sample size and the species' behavioral ecology.
准确估计灵长类动物的活动范围很重要,但方法差异很大。本文通过比较生活在巴西亚马逊地区森林片段和连续森林中的北方髯猴(Chiropotes satanas chiropotes)的活动范围估计值,研究了最小凸多边形(MCP)、自适应核(AK)和固定核(FK)估计器的准确性。当样本量较小时,MCP在计算活动范围和日间活动范围方面比AK和FK更准确,而AK最常高估活动范围。考虑各种活动范围估计方法很重要,因为合适的方法可能取决于样本量和物种的行为生态学。
