Comparative analysis of zooplankton diversity in freshwaters: What can we gain from metagenomic analysis?

Environmental DNA, Volume 4, Issue 6, Page 1250-1264, November 2022., 2022
We analyzed water sample metagenomes to estimate zooplankton diversity in 22 freshwater lakes across eastern Canada. We tested the coherence of data based on morphologically identified zooplankton taxa and molecular genetic data derived from shotgun sequencing of environmental DNA collected at the same time.
