Contrasting prevalence of selection and drift in the community structuring of bacteria and microbial eukaryotes
Summary Whether or not communities of microbial eukaryotes are structured in the same way as bacteria is a general and poorly explored question in ecology. Here, we investigated this question in a set of planktonic lake microbiotas in Eastern Antarctica that represent a natural community ecology exp...

In sum, we conclude that microeukaryotes and bacteria inhabiting the same communities can be structured predominantly by different processes.
