Évaluation des effets de l’augmentation des débits réservés à l’aval de deux barrages du Haut-Rhône français à l’aide de l’examen des communautés d’oligochètes
Des travaux de restauration du chenal central du Haut-Rhône français à l’aval des barrages de Lavours et Champagneux ont été entrepris en 2005-2006 et ont consisté à augmenter les débits réservés. Les effets de cette opération ont été évalués en étudiant e ...
2021Effect thresholds of metals in stream sediments based on in situ oligochaete communities
Benoît Jean Dominique Ferrari, Régis Lionel Vivien
Aquatic oligochaetes, comprising a large number of species showing various degrees of resistance to chemical pollution, are recognized as valuable bioindicators of sediments’ quality. In the Geneva area (Switzerland), oligochaete tools were previously test ...
2020Assessment of abundance and community composition of benthic macroinvertebrates: recommendations for improved sampling, fixation and extraction of oligochaetes
Benoît Jean Dominique Ferrari, Régis Lionel Vivien
For several decades, the abundance and community structure of benthic macroinvertebrates have been studied to assess the biological quality of aquatic ecosystems. Procedures aiming at studying the whole of macroinvertebrate communities were mainly designed ...
2020The foreign oligochaete species Quistadrilus multisetosus (Smith, 1900) in Lake Geneva: morphological and molecular characterization and environmental influences on its distribution
Benoît Jean Dominique Ferrari, Régis Lionel Vivien
The presence of the oligochaete species Quistadrilus multisetosus (Smith, 1900) originating from North America has been mentioned for several decades in Europe, the Middle East and Russia. Its distribution and abundance in Europe is still unknown but it ca ...
2020High-throughput DNA barcoding of oligochaetes for abundance-based indices to assess the biological quality of sediments in streams and lakes
Benoît Jean Dominique Ferrari, Régis Lionel Vivien
Aquatic oligochaete communities are valuable indicators of the biological quality of sediments in streams and lakes, but identification of specimens to the species level based on morphological features requires solid expertise in taxonomy and is possible o ...
2020Testing different (e)DNA metabarcoding approaches to assess aquatic oligochaete diversity and the biological quality of sediments
Aquatic oligochaetes are important bioindicators of sediment quality in watercourses and lakes, but their morphological identification to the species level is challenging and sometimes impossible. The use of DNA barcoding and metabarcoding could greatly fac ...
2019Assessment of the effects of wastewater treatment plant effluents on receiving streams using oligochaete communities of the porous matrix
Human activities can disturb the natural dynamics of exchanges between surface water and groundwater in rivers. Such exchanges contribute to the self-purification of the environment and an excess of infiltration can lead to contamination of groundwater. In ...
2019Development and implementation of eco-genomic tools for aquatic ecosystem biomonitoring: the SYNAQUA French-Swiss program
The effectiveness of environmental protection measures is based on the early identification and diagnosis of anthropogenic pressures. Similarly, restoration actions require precise monitoring of changes in the ecological quality of ecosystems, in order to ...
SPRINGER HEIDELBERG2018Simultaneous preservation of the DNA quality, the community composition and the density of freshwater oligochaetes for the development of genetically based biological indices
Introduction. Oligochaetes are recognized as valuable bioindicators of sediment quality in streams and lakes. The development of an oligochaete index based on the identification of specimens using DNA barcodes requires a method for simultaneously preservin ...
2018Cytochrome c oxidase barcodes for aquatic oligochaete identification: development of a Swiss reference database
Introduction. Aquatic oligochaetes represent valuable indicators of the quality of sediments of watercourses and lakes, but their difficult identification based on morphological criteria compromises their more common use for eco-diagnostic analyses. This i ...
