Abstract

ABSTRACT Several studies assert that transportation infrastructure rights-of-way can play a positive role for many animal species, especially in highly fragmented and human-dominated landscapes. This study examines the contribution of highway stormwater ponds to amphibian ecological networks, questioning both the influence of their location on species richness and their capacity to increase landscape connectivity. The ecological networks of amphibian species were modeled by graph theory around highway A77 (France). Stormwater ponds as well as natural ponds were included as potential habitats and several connectivity metrics were calculated at different scales. The connectivity values of the stormwater ponds were analyzed in relation to species presence data collected in 2018. While most of these ponds contribute little to regional connectivity, some of them represent important connector patches. Statistical analysis also suggests that highway ponds are used by amphibians in areas with few natural pools. This raises questions about how to improve the management of ecological networks by considering the capacity of artificial habitats to serve as a refuge for biodiversity.

公路雨水池对两栖动物生态网络连通性的贡献有多大?

摘要几项研究表明，交通基础设施通行权对许多动物物种都有积极作用，尤其是在高度分散和以人为主导的景观中。这项研究考察了公路雨水池对两栖动物生态网络的贡献，质疑其位置对物种丰富度的影响及其增加景观连通性的能力。两栖动物物种的生态网络是通过图论围绕A77公路（法国）建模的。雨水池塘和天然池塘被列为潜在栖息地，并在不同尺度上计算了几个连通性指标。结合2018年收集的物种存在数据分析了雨水池的连通性值。虽然大多数池塘对区域连通性的贡献很小，但其中一些池塘代表了重要的连接补丁。统计分析还表明，在天然水池很少的地区，公路池塘被两栖动物使用。这就提出了如何通过考虑人工栖息地作为生物多样性避难所的能力来改善生态网络管理的问题。
