Abstract

Snake response to habitat changes is frequently investigated at the species level, but it is still poorly known how snakes respond to habitat changes at the community level and at which spatial scale. Here, we used a multi-model inference approach to evaluate the effects of local and landscape composition (percentage of forest cover and silviculture) and habitat fragmentation (number of forest patches and total edge) on species, functional, and phylogenetic diversity of snake communities in tropical fragmented landscapes. Additionally, we tested whether silviculture acted as an environmental filter for snakes. Species and functional diversity responded primarily to landscape elements: species richness, abundance, and functional diversity decreased with deforestation. In addition, species richness and abundance increased with the proportion of forest and the number of patches in the landscape. In contrast, phylogenetic diversity was driven by the local habitat composition. Although habitat types did not filter entire clades and functional groups, each species tended to have a co-occurring species with similar traits (at landscape level) and a close relative (at both levels) in impacted habitats. In contrast, the co-occurrence of close relatives and functionally similar species was avoided in the native forest. Our findings indicate that snake responses to habitat changes occur on multiple scales and highlight the importance of conserving native forests to maintain multiple components of biodiversity. Strategies for conserving snake diversity in tropical fragmented landscapes should therefore consider management practices at both the local and landscape scales.

生境变化对雨林蛇类多样性的多尺度影响
摘要 蛇类对生境变化的响应经常在物种水平上进行研究,但对蛇类如何在群落水平上以及在何种空间尺度上对生境变化做出响应还知之甚少。在此,我们采用多模型推断法评估了热带破碎景观中地方和景观组成(森林覆盖率和造林)以及栖息地破碎化(森林斑块数量和总边缘)对蛇群落的物种、功能和系统发育多样性的影响。此外,我们还测试了造林是否对蛇类起到了环境过滤的作用。物种和功能多样性主要受景观要素的影响:物种丰富度、丰度和功能多样性随森林砍伐而降低。此外,物种丰富度和丰度随着景观中森林比例和斑块数量的增加而增加。相比之下,系统发育多样性则受当地栖息地组成的影响。虽然栖息地类型并不能过滤整个支系和功能群,但在受影响的栖息地中,每个物种往往都有一个性状相似的共生物种(在景观水平上)和一个近亲物种(在两个水平上)。与此相反,在原生林中则避免了近亲和功能相似物种的共存。我们的研究结果表明,蛇类对栖息地变化的反应发生在多个尺度上,并强调了保护原生林以维持生物多样性多个组成部分的重要性。因此,在热带破碎景观中保护蛇类多样性的策略应考虑当地和景观尺度的管理措施。

期刊介绍: Biodiversity and Conservation is an international journal that publishes articles on all aspects of biological diversity-its description, analysis and conservation, and its controlled rational use by humankind. The scope of Biodiversity and Conservation is wide and multidisciplinary, and embraces all life-forms. The journal presents research papers, as well as editorials, comments and research notes on biodiversity and conservation, and contributions dealing with the practicalities of conservation management, economic, social and political issues. The journal provides a forum for examining conflicts between sustainable development and human dependence on biodiversity in agriculture, environmental management and biotechnology, and encourages contributions from developing countries to promote broad global perspectives on matters of biodiversity and conservation.
