| 摘 要： | 为了解栖息地片段化对鸟类巢捕食风险的影响,我们于2010年4-8月,在千岛湖地区选取16个岛屿,分别在岛屿边缘和内部区域用放置鸡蛋(大型卵)和鹌鹑(Coturnix japonica)蛋(小型卵)的方法进行人工模拟地面巢试验,研究不同体积大小鸟卵的巢捕食率及其差异,分析巢捕食率与岛屿面积、隔离度、形状指数和植物物种丰富...

| Abstract: | To investigate the effects of habitat fragmentation on avian nest predation risk,we placed 726 artificial ground nests with chicken or quail(Coturnix japonica) eggs on 16 islands in edge and interior locations in Thousand Island Lake from April to August 2010.We compared nest predation rates between nests with different egg types and between the nests located at different distances from the edge.We also evaluated the relationships between nest predation and island area,isolation,shape index and plant richne... |
