Long-term dynamics in microbial eukaryotes communities: a palaeolimnological view based on sedimentary DNA
International audience Assessing the extent to which changes in lacustrine biodiversity are affected by anthropogenic or climatic forces requires extensive palaeolimnological data. We used high-throughput sequencing to generate time-series data encompassing over 2200 years of microbial eukaryotes (p...
