ABSTRACT

Dam installation causes profound changes in the structure and quality of aquatic habitats, transforming the lotic upstream stretches in lentic habitats and severely modifying hydrologic and sedimentary patterns downstream. As many impacts cannot be avoided, conservation actions are often implemented to minimize ecological losses. Translocation is a conservation tool that can be used to mitigate dams’ impacts on freshwater species, particularly those having restricted mobility. Building from the experience of translocations actions of freshwaters mussels carried out in Portugal by the authors, and the available literature, we address the challenges of planning, executing, and following up translocations of freshwater mussels. The guidelines presented increase chances of conducting successful freshwater mussels translocations and also provide guidance for others biological groups and project types.

通过易位将水坝对生物多样性的影响降至最低:淡水贻贝为例

抽象的

大坝的安装引起水生生境结构和质量的深刻变化,改变了透镜状生境上游的抽水作用,并严重改变了下游的水文和沉积模式。由于无法避免许多影响,因此经常采取保护措施以最大程度地减少生态损失。易位是一种保护工具,可用于减轻大坝对淡水物种的影响,尤其是那些流动性受限的物种。基于作者在葡萄牙进行的淡水贻贝易位行为的经验以及现有文献的基础上,我们解决了淡水贻贝易位的计划,执行和跟进的挑战。
