摘要:

为了解栖息地片段化对次级洞巢鸟营巢资源利用的影响, 我们于2008年2-8月, 在千岛湖地区选取21个岛屿, 采用悬挂人工巢箱方法进行大山雀(Parus major)招引实验。通过测定岛屿面积、岛屿隔离度、捕食者活动率、人工巢箱周围植被盖度和人工巢箱巢向等5种参数, 分析大山雀人工巢箱利用与上述参数间的关系。实验期间, 共悬挂443个人工巢箱, 其中有72个(16.3%)被大山雀利用。大山雀倾向于选择捕食者活动率低、植被盖度低、巢口向东或向南的人工巢箱; 岛屿面积和隔离度对大山雀利用人工巢箱不存在显著的直接影响, 但岛屿面积可通过影响捕食者的活动率, 对大山雀利用人工巢箱产生间接影响。因此, 我们认为在栖息地片段化后, 应更多关注对洞巢鸟营巢资源利用有直接影响的栖息地特征因素, 以及片段化效应的间接影响。

Abstract:

To investigate the effects of habitat fragmentation on the use of nest site resources by a secondary cavity-nesting bird species, the great tit (Parus major), we placed 443 artificial nest boxes on 21 islands in Thousand Island Lake from February to August 2008. Among the nest boxes 72 (16.3%) were used by great tits. We analyzed the relationships between island area, island isolation, predator activity, vegetation cover and nest box orientation and the use of nest boxes by great tits. Great tits preferred nest boxes with lower predator activity, lower vegetation cover, and an eastern or southern orientation. Island area and isolation did not affect the use of nest boxes directly, but island area indirectly influenced the use of nest boxes by affecting predator activity. Our results suggest that attention should be paid to environmental variables that directly affect the use of nest site resources by great tits. Our study also highlights the importance of the indirect effects of habitat fragmentation on the use of nest site resources by great tits.

Key words: Parus major, artificial nest box, use of nest site resource, habitat fragmentation, the Thousand Island Lake
