Metadata for: Ecosystem and mixoplankton responses to pulsed allochthonous inputs to lake mesocosms

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.

本研究旨在厘清生态系统对不同类型与施用节律的外源输入（allochthonous inputs）的响应，重点聚焦微型浮游植物（nanophytoplankton）对这类事件的自养与混养（噬菌作用，bacterivory）响应。我们于2022年夏季在特里同湖（Lac Triton）的劳伦琴生物站（Station de biologie des Laurentides）开展了一项湖内围隔中宇宙实验（mesocosm experiment），以脉冲形式向湖内围隔装置中添加有机质，供试有机质包括昆虫幼虫、树叶或二者的组合。本实验采集了一系列响应变量，用以表征生态系统代谢水平、群落组成结构，以及自养、异养与混养活动的相对贡献占比。
