摘  要:
[目的]揭示松鼠贮食时对红松松塔的选择特征。[方法]通过样线调查的方法收集松鼠贮食时丢弃的松塔核,测量其长宽数据。根据已经建立的松塔质量评价标准进行分析。[结果]无论在哪个贮食阶段,松鼠都倾向于选择较大的松塔贮藏,且将最大的松塔贮藏在距离母树林150~300 m的范围内。[结论]松鼠选择较大的松塔贮藏以降低贮藏能耗,获得最大的能量收益。

摘  要:
[Objective] The research aims to reveal the Sciurus vulgaris' selectivity of Pinus koraiensis cones during hoarding pine seeds.[Method] According to line-transect investigation,we collected and measured the data of length and width of the cone cores abandoned by Sciurus vulgaris while they hoarded.Then the obtained data were analyzed by quantitative evaluation standard that we previously established.[Result] No matter in which hoarding phase,Sciurus vulgaris were apt to select the larger cones for storage and hoarded the largest cones within 150-300 m away from the parent forest.[Conclusion] During hoarding pine seeds,Sciurus vulgaris selected the larger pine cones in order to reduce energy consumption and gain the maximum energy incomes.
