In Canada, lakes and rivers are dominant features of the landscape, butknowledge of freshwater diversity of microorganisms at the base of food webs is still in infancy. The proposed research program will provide a fresh approach to microbial biodiversity, using freshwater zooplankton as a model community and a heuristic framework integrating community ecology, functional traits and phylogenetic biology. The research program involves a mix of database analyses and field studies. Four projects will be developed across scales (continental, regional and local) and ecosystems (lakes, rivers and ponds), using my unique database on zooplankton communities in Canadian lakes, and field studies in the St. Lawrence River, peri-urban lakes and urban ponds in Southern Québec. To address the research objectives, we will examine: 1. How the latitudinal temperature gradient determines crustacean zooplankton taxonomic, functional and phylogenetic diversity at the continental scale of Canada? 2. How regional landscape features, anthropogenic disturbances, and local environmental filters regulate zooplankton diversity and community structure in boreal lake districts? 3. How structural complexity of submerged vegetation affects zooplankton species richness, community structure and functional diversity in rivers and lakes? 4. How zooplankton biodiversity is distributed among taxonomic and functional groups, and ecosystems in peri-urban and urban landscapes? One of our primary goals is to train highly qualified personnel in aquatic community ecology and biodiversity science. Through the proposed research program, I will train 2 PDF, 3 Ph.D., 3 M.Sc., 2 Master, and at least 3 undergraduate students. I will offer training in theoretical ecology, zooplankton ecology, spatial modelling, macroecology, biodiversity, phylogeny, functional traits, and urban ecology. The research will lead to several deliverables and products: i) species and trait distribution maps for Canadian zooplankton, ii) a complete database on taxonomical, functional and phylogenetic diversity metrics for Canadian zooplankton, iii) metadata on freshwater zooplankton from different sources across scales linking zooplankton structure to environmental conditions, iv) scientific papers in high quality scientific journals, v) new imaging system application for analysing zooplankton functional groups in fresh waters, vi) bioassessment tools for evaluating ecological integrity and biodiversity conservation of aquatic biota in urban landscapes. Finally, I would like to edit a book on the systematics, taxonomy and distribution of freshwater copepods in Canada as the legacy of my long-term research on zooplankton ecology.Overall, my research program will give a better understanding of mechanisms that structure microbial life in fresh waters, and contribute to conservation of aquatic ecosystems.

在加拿大，湖泊和河流是景观的主要特征，但对食物网基础上的淡水微生物多样性的认识仍处于起步阶段。该研究计划将为微生物生物多样性研究提供一种新的方法，以淡水浮游动物为模式群落，并将群落生态学，功能性状和系统发育生物学结合起来。该研究计划涉及数据库分析和实地研究的混合。四个项目将开发跨尺度（大陆，区域和地方）和生态系统（湖泊，河流和池塘），使用我独特的数据库在加拿大湖泊浮游动物群落，并在圣劳伦斯河，城郊湖泊和城市池塘在魁北克省南部的实地研究。为了实现研究目标，我们将研究： 1.纬度温度梯度如何决定加拿大大陆尺度上甲壳类浮游动物分类、功能和系统发育多样性？ 2.区域景观特征、人为干扰和当地环境过滤器如何调节北方湖区浮游动物多样性和群落结构？ 3.河湖沉水植被结构复杂性对浮游动物物种丰富度、群落结构和功能多样性的影响？ 4.浮游动物生物多样性在分类和功能群以及城郊和城市景观生态系统中的分布情况如何？ 我们的主要目标之一是培养水生群落生态学和生物多样性科学方面的高素质人才。通过拟议的研究计划，我将培养2名PDF，3名博士，3名硕士，硕士2名，本科生3名以上。我将提供理论生态学，浮游动物生态学，空间建模，宏观生态学，生物多样性，生物发生学，功能特性和城市生态学的培训。该研究将产生若干可交付成果和产品：i）加拿大浮游动物的物种和特征分布图，ii）加拿大浮游动物分类学，功能和系统发育多样性指标的完整数据库，iii）将浮游动物结构与环境条件联系起来的不同来源的淡水浮游动物元数据，iv）高质量科学期刊上的科学论文，五）新的成像系统应用于分析淡水沃茨中的浮游动物功能群，六）生物评估工具，用于评估城市景观中水生生物群的生态完整性和生物多样性保护。最后，我想编辑一本关于加拿大淡水桡足类的系统学、分类学和分布的书，作为我长期研究浮游动物生态学的遗产。总的来说，我的研究计划将使我更好地了解淡水沃茨中微生物生命的结构机制，并为水生生态系统的保护做出贡献。
