Environmental DNA metabarcoding revealing the distinct responses of phytoplankton and zooplankton to cascade dams along a river-way

As the crucial components of river ecosystem, the responses of phytoplankton and zooplankton to cascade dams have rarely been studied simultaneously, and thus, lacking the understanding of the difference in succession between them. Here, we investigated the phytoplankton and zooplankton communities in a river-way with cascade dams using an environmental DNA metabarcoding technology.

浮游植物与浮游动物作为河流生态系统的关键组成部分，二者对梯级大坝的响应鲜有被同时开展研究的案例，因此学界对二者群落演替的差异仍缺乏系统认知。本研究采用环境DNA宏条形码（environmental DNA metabarcoding）技术，对一座建有梯级大坝的河道中的浮游植物与浮游动物群落进行了调查。
