Understanding the dynamic of harmful algal blooms in boreal lakes of Abitibi-Temiscamingue

Cyanobacteria are the Earth’s oldest photoautotrophs and responsible for today’s oxygen level. However, when they overgrow and form a bloom, they cause ecological degradation and sometimes become life threatening because of the cyanotoxins they produce. This phenomenon is linked to high concentrations of nutrients, elevated water temperature and low water movement. Recent observations showed some unusual occurrence of harmful cyanobacterial blooms under the ice cover. This study aims to better understand the seasonal dynamic of harmful algal blooms in boreal lakes by identifying the specific driving factors responsible for their development in two lakes of Abitibi-Témiscamingue (Quebec, Canada). The outcomes of the project will contribute to develop comprehensive knowledge and new tools for improving water quality for Lake Beauchamp near the city of Amos and Lake Fortune, for which the watershed organisation of Temiscamingue is building a new management plan and for all Canadian lakes.
