eDNA (AnaEE France)

Analysis and Experimentation on Ecosystems

Platform manager : Stephen MULERO
Scientific manager : Frédéric BOYER

 

The AnaEE technical platform has been set up to allow ecologists to perform large-scale analysis of environmental DNA via a metabarcoding approach. DNA metabarcoding refers to high throughput DNA-based identification of multiple species from environmental DNA. The main applications of this technique consist in diet analysis from feces, in biodiversity inventory from soil samples, and in palaeo-environment reconstruction using lake sediments and permafrost samples.

The personnel involved in the eDNA platform is qualified to assist researchers in the following steps of the analysis of environmental samples :

  • conception of the experimental design
    (e.g. how many samples should be taken ?
    how many sequence reads are required ?
    how many positive and negative controls should be done ?
    how to produce the reference database ?)
  • wet lab analysis  
    (i.e., DNA extraction from the environmental sample and PCR-based amplification of selected regions)
  • standard bioinformatic analysis of sequencing output
    (using a collection of program developed within the eDNA platform, and specifically dedicated to DNA metabarcoding : the OBITools)
  • advice on the interpretation of results, especially on methodological limits

 

Note that next generation sequencing is performed using the Illumina technology and outsourced outside of the eDNA platform.

The eDNA platform has experience working on various environmental matrices : soil, lake sediments, permafrost, and feces. It also has experience with the identification of various groups of organisms within these matrices, including plants, vertebrates, arthropods, earthworms, fungi, bacteria.
