The research objective was to understand ecosystemic responses to different types and schedules of allochthonous inputs, with a focus on the autotrophic and mixotrophic (bacterivory) responses of nanophytoplankton to such events. We conducted a mesocosm experiment in the summer of 2022 in which we added organic matter as pulses, either through insect larvae, tree leaves or a combination of both to in-lake mesocosms (Lac Triton, Station de biologie des Laurentides). A range of response variables was sampled to capture ecosystem metabolism, community composition, and the relative contributions of autotrophic, heterotrophic and mixotrophic activities.
