【摘要】：2009年3~7月,在西藏自治区墨竹工卡县日多乡念村(29o46′N,92o19′~92o20′E,海拔4 423~5 015 m),采用目标动物抽样法对高原鼠兔(Ochotona curzoniae)的警戒行为和取食行为进行了观察,利用广义线性模型(GLM)的泊松回归模型分析了不同土地利用、植被覆盖度、植物类别和植被优势种对高原鼠兔行为影响的差异。研究结果表明,雌性高原鼠兔取食行为频率高于雄性(β=㧟0.203,SE=0.096,P0.05),警戒行为频率低于雄性(β=0.199,SE=0.088,P0.05)。高原鼠兔的取食行为(β=㧟0.009,SE=0.004,P0.05)随着栖息地内双子叶植物覆盖比例增高而呈递减趋势,相应地,随着栖息地内单子叶植物覆盖比例的增高呈现递增趋势(β=0.009,SE=0.004,P0.05)。高原鼠兔的警戒行为在放牧地(β=0.273,SE=0.131,P0.05)以及植被覆盖度高的栖息地内(β=0.007,SE=0.003,P0.05)均呈递增趋势。随着薹草属植物覆盖度比例增高,高原鼠兔的取食行为(β=0.023,SE=0.006,P0.001)呈现递增趋势,而警戒行为呈递减趋势(β=㧟0.018,SE=0.007,P0.05)。
[Abstract]:In March to July 2009 , the vigilance behavior and feeding behavior of Ochotona curzoniae were studied by using the Poisson regression model of the generalized linear model ( GLM ) . The results showed that the frequency of feeding behavior was higher in female plateau than in males ( 尾 = ? 0.203 , SE = 0.096 , P0.05 ) . The frequency of vigilance behavior was lower than that in males ( 尾 = 0.199 , SE = 0.088 , P0.05 ) . The feeding behavior ( 尾 = ? 0 . 009 , SE = 0.004 , P 0 . 05 ) of high altitude rat rabbits showed a decreasing trend with the increase of the proportion of plant covering in the habitat . Correspondingly , with the increase of the proportion of the monocotyledon in the habitat , the increasing trend ( 尾 = 0 . 009 , SE = 0.004 , P < 0 . 05 ) . There was an increasing trend of vigilance behavior in plateau pikas ( 尾 = 0.273 , SE = 0.131 , P0.05 ) and high vegetation coverage ( 尾 = 0.007 , SE = 0.003 , P0.05 ) .
