Tasks at the Ecotox Centre

  • Implementation, validation and development of biological methods based on the study of oligochaete and nematode communities for the assessment of the quality of sediments in watercourses and lakes
  • Development of an oligochaete index based on the identification of species with DNA barcodes (Next-generation sequencing)
  • Building of a DNA-barcode (COI) library for oligochaete species
  • Development and optimisation of sediment ecotoxicological tests, maintenance of cultures of benthic organisms

Areas of Expertise

  • Classical systematics : aquatic oligochaetes, initiation of works on aquatic nematodes
  • Molecular systematics
  • Aquatic ecology : establishment of ecological diagnoses, effects of sediment pollutants (metals, PCBs, PAHs) on oligochaete communities, establishment of in situ toxicity thresholds,
  • Sediment ecotoxicology
