Small shallow lakes (SSL) are reservoirs of biodiversity and provide numerous ecosystem services. Therefore, tools to easily and rapidly assess the biological integrity and conservation value of these aquatic ecosystems have been increasingly requested by environmental managers. In this study, we propose a new sampling method for monitoring aquatic invertebrates. This method, called S₃i, allows to sample SSL with a surface area from 1 m² to at least 20 ha. We applied the method to 268 SSL in France and used generalised additive models to investigate factors that correlate with (1) total richness, and (2) richness and relative abundance of functional group ε, i.e. group of taxa exclusive of SSL richness and determining SSL functioning. Elevation, surface area, and distance from the source—a proxy of river and watershed connectivity—were identified as determinants of invertebrate richness. Invasive crayfish may directly impact total and ε-richness, whereas fish impact ε-richness and ε-abundances. Shoreline vegetation and vegetation cover were especially determinant for total richness, ε-richness, and ε-relative abundance. The S₃i was successfully applied to a wide diversity of SSL in France. The sampling method can be considered as rapid, reproductible, and representative for monitoring aquatic invertebrates in SSL and should be applied to the management of a worldwide range of small shallow lakes.

小型浅湖 (SSL) 是生物多样性的蓄水池，可提供众多生态系统服务。因此，环境管理者越来越需要能够轻松快速地评估这些水生生态系统的生物完整性和保护价值的工具。在这项研究中，我们提出了一种监测水生无脊椎动物的新采样方法。这种称为 S ₃ i 的方法允许对表面积从 1 m ²到至少 20 ha 的SSL 进行采样。我们将该方法应用于法国的 268 SSL 并使用广义加性模型来研究与 (1) 总丰富度和 (2) 官能团ε 的丰富度和相对丰度相关的因素，即不包括 SSL 丰富性和确定 SSL 功能的分类群。海拔、表面积和与源头的距离——河流和流域连通性的代表——被确定为无脊椎动物丰富度的决定因素。入侵小龙虾可能直接影响总丰度和ε丰度，而鱼类则影响ε丰度和ε丰度。海岸线植被和植被覆盖对总丰富度、ε -丰富度和ε -相对丰度具有特别的决定作用。S ₃我已成功应用于法国广泛多样的SSL。该采样方法可以被认为是监测 SSL 中水生无脊椎动物的快速、可重复和具有代表性的方法，应应用于全球范围内小型浅水湖泊的管理。
