💧Les écosystèmes d’eau douce deviennent de plus en plus salés. Voici un article écrit par Alison et basé sur les recherches effectuées dans le labo!

Les écosystèmes d’eau douce deviennent de plus en plus salés. Voici pourquoi c’est inquiétant Bien qu’elle ait été considérablement moins étudiée que d’autres problèmes environnementaux, la salinisation présente des défis majeurs pour la biodiversité des eaux douces et des zones côtières.

St. Lawrence River zones that are hostile to invasive species can be refuges for native fish Wetlands can help limit the spread of the voracious round goby, an invasive species that has infiltrated the Great Lakes and has become widespread in the St. Lawrence River.

Views and vistas from hiking our research equipment to study mountain lakes in the Canadian Rockies for Julien Beaulieu's PhD, Daphné Trépanier-Leroux's MSc, and Matthew Yates's PDF research.

Julien Beaulieu is a PhD student working on a whole lakes experiment in the Canadian Rockies in collaboration with the fraser lab. His project objective is to study the effect of size-selective harvesting on brook trout spatial distribution using eRNA, their diet, prey communities and ecosystems metabolism. He is currently working on a side project looking at aquatic invertebrate recovery after rotenone application.

Congratulations to PhD student Cristina Charette on being interviewed about her doctoral research for the famous Québec TV program, La Semaine Verte, last week. Her project addresses the impacts of invasive round goby fish on food web quality and contaminant transfer in the Upper St. Lawrence River. Stay tuned for a link to the program :)

This is the miniature house that we rented last summer to do our lake research in Alaska. Notice our plankton nets hanging out front! Next time we won't rent a house quite as miniature, we realized.

This is another one of our lab boats: 'The Whirligig', named after the aquatic beetle that has eyes that enable it to see both above and below the water as it skims along the surface. We keep it in Alaska for our lake research there. Shown here from last summer with myself, and MSc students Mariane and Sarah (L to R).
