中文摘要:赤腹松鼠Callosciueus erythraeus在四川省洪雅县已经成为第一大森林害鼠。为了揭示赤腹松鼠巢址选择特征并为控制该物种的危害服务,20083~8月采取样线法对洪雅县赤腹松鼠的巢址选择状况进行了调查。共发现81棵巢树,对其巢位参数的统计显示,赤腹松鼠可在11种阔叶树和3种针叶树上营巢,对柏木Cpuressus funebris和楠木Phoebe zhennan有明显选择性,分别为营巢树数量的34.6%33.3%。营巢树平均高度为18.6 m±0.6 m,巢距地面平均高度为16.2 m±0.5 m,巢位置一般靠近树的顶端,多朝东、南和东南方向,76.5%的巢位于树干与树枝的交界处。对无重复取样的巢址样方(n=65)和对照样方(n=65)15个生境因子的对比分析表明,赤腹松鼠倾向在乔木平均高度较高、林下灌木盖度相对较高、坡度较大的生境中营巢。
英文摘要:Information on habitat requirement is crucial for the management and control of tree squirrels. The red-bellied squirrel (Callosciueus erythraeus) has become the principle pest species in the forests of Hongya County, Sichuan Province. In order to better control its damage to trees, a study concerning nest-site selection by the red-bellied squirrel was conducted in Hongya County, from March to August, 2008. A total of 81 nests were found by the line transect method. Nests were built in 11 broadleaf species and 3 conifer species, significantly in the Chinese weeping cypress (Cpuressus funebris)and Nanmu (Phoebe zhennan), accounting for 34.6% and 33.3% of nests, respectively. The average height of nesting trees was 18.6 m±0.6 m and the average height of nests was 16.2 m±0.5 m. Nests were generally placed close to the apex of trees, more frequently towards the east, south and southeast. 76.5% nests were located at the trunk-branch junction. 15 habitat factors were compared between nest sites (n=65) and random sites (n=65). The results indicated that red-bellied squirrels significantly preferred to build nests in habitats with higher surrounding trees, greater shrub coverage and steeper slope gradients.
