摘要(Abstract):
应用目标取样法和扫描取样法同时对5只圈养黑熊(Ursus thibetanus)的15种行为进行了观察和记录,并对两种方法所得结果进行比较和讨论,评估两种方法在动物行为学研究中的可靠性。结果表明:两种方法所得的行为实际频次间存在显著差异(χ2=4.388,P=0.036,df=1),相对频次间无显著差异(χ2=0.468,P=0.494,df=1);行为持续时间的长短是影响两种方法所得结果间差异的主要因素,其与相对偏差值(Rela-tive Deviation,RD)之间存在显著的负相关关系(实际频次:r=-0.900,P=0.000,df=13;相对频次:r=-0.898,P=0.000,df=13);两种方法所得行为发生频次间存在显著正相关关系(r=0.965,P=0.000,df=13);扫描取样法所得行为间的差异性分析结果中70.5%与目标取样法的分析结果一致,29.5%存在分歧,且在分歧组中,参与差异性分析的两种行为的持续时间之差极显著大于一致组(χ2=10.082,P=0.001,df=1)。
