Area of Science:

  • Aquatic Ecology
  • Environmental DNA (eDNA) Metabarcoding
  • Conservation Biology

Background:

  • Anthropogenic disturbances impact aquatic habitats in river networks.
  • Fish serve as bioindicator taxa for assessing habitat quality.
  • Environmental DNA (eDNA) metabarcoding offers a novel biomonitoring approach.

Purpose of the Study:

  • To assess habitat quality and fragmentation in southern Québec watersheds using a trait-based biomonitoring framework.
  • To evaluate fish community tolerance to pollution and its correlation with environmental factors.
  • To explore the utility of eDNA metabarcoding for large-scale riverine ecosystem health assessments.

Main Methods:

  • Sampling of 193 sites across the Châteauguay and St. François watersheds.
  • Estimation of fish community tolerance indices using 12S eDNA metabarcoding.
  • Application of random-forest modelling to predict fish community tolerance in unsampled areas.

Main Results:

  • A significant correlation was found between fish community tolerance index and environmental factors (land use, precipitation, elevation).
  • River fragmentation by dams altered fish assemblages and native fish movement, while impeding non-native common carp spread.
  • eDNA metabarcoding provided a cost-effective, non-invasive assessment of fish biodiversity and riverine health.

Conclusions:

  • eDNA metabarcoding is a powerful tool for large-scale biomonitoring and assessing river fragmentation impacts.
  • Fish tolerance indices, linked to environmental factors, offer insights into aquatic habitat quality.
  • This approach enhances understanding of riverine ecosystem health and informs conservation strategies.
