The biodiversity and biogeography of protists inhabiting many ecosystems have been intensely studied using different sequencing approaches, but tropical ecosystems are relatively under-studied. Here, we sampled planktonic waters from 32 lakes associated with four different river-floodplains systems in Brazil, and sequenced the DNA using a metabarcoding approach with general eukaryotic primers. The lakes were dominated by the largely free-living Discoba (mostly the Euglenida), Ciliophora, and Ochrophyta. There was low community similarity between lakes even within the same river-floodplain. The protists inhabiting these floodplain systems comprise part of the large and relatively undiscovered diversity in the tropics.
利用不同的测序方法，对栖息在许多生态系统中的原生生物的生物多样性和生物地理学进行了深入研究，但对热带生态系统的研究相对较少。在这里，我们从巴西四个不同的河流泛滥平原系统相关的 32 个湖泊中采集了浮游水样本，并使用通用真核生物引物的宏条形码方法对 DNA 进行了测序。这些湖泊主要由自由生活的 Discoba（主要是 Euglenida）、纤毛虫和 Ochrophyta 组成。即使在同一河流泛滥平原内，湖泊之间的群落相似性也很低。栖息在这些泛滥平原系统中的原生生物是热带地区大量尚未被发现的多样性的一部分。
