Metagenomic analysis of metazoan diversity across Canadian lakes
Global changes threaten lake ecosystems and facilitate invasions by non-native species, which may greatly modify ecosystems and reduce services derived from lakes. Environmental DNA (eDNA) approaches are broadly used to assess biodiversity trends in aquatic environments. Environmental metagenomics (shotgun sequencing of an environmental sample) has recently emerged as a powerful approach to recover taxonomic and genetic diversity of whole taxonomic groups of plants and animals from water and sediment. The main goals of my project are to 1- determine the effectiveness of metagenomes of water samples in detecting metazoan diversity, and 2- determine how diversity derived from metagenomes compares with metabarcoding and morphologically-identified datasets. In a first step, I will validate the approach using datasets of zooplankton and rotifers and in a second step, I will extend the study to other groups of aquatic metazoans (e.g. fish and molluscs). This project is part of the LakePulse Network, a pan-Canadian initiative that aims at assessing the health of lakes across the country.
