千岛湖两栖爬行类动物群落结构嵌套分析

Nested species subsets of amphibians and reptiles in Thousand Island Lake

  • 摘要: 生境片段化是导致生物多样性降低的主要原因之一。该文采用样线法对千岛湖23个岛屿的两栖爬行类进行了调查, 并结合植物种类调查数据和GIS技术提取的栖息地景观参数, 使用“BINMATNEST”软件和Spearman相关性分析等方法, 对这些岛屿上的两栖爬行类群落的分布格局及其影响因素进行分析。结果表明, 千岛湖两栖爬行类群落整体上呈现嵌套分布格局; 嵌套格局与岛屿面积和生境类型相关显著。因此, 在制定千岛湖地区两栖爬行动物保护措施时, 应优先考虑面积较大和生境类型多的岛屿。

     

    Abstract: Habitat fragmentation is a main cause for the loss of biological diversity. Combining line-transect methods to survey the amphibians and reptiles on 23 islands on Thousand Island Lake in Zhejiang province, along with survey data on nearby plant species and habitat variables collected by GIS, we used the “BINMATNEST (binary matrix nestedness temperature calculator)” software and the Spearman rank correlation to examine whether amphibians and reptiles followed nested subsets and their influencing factors. The results showed that amphibians and reptiles were significantly nested, and that the island area and habitat type were significantly associated with their nested ranks. Therefore, to effectively protect amphibians and reptiles in the Thousand Islands Lake area we should pay prior attention to islands with larger areas and more habitat types.
