项目摘要

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了解仍处于起步阶段。拟议的研究计划将以淡水浮游动物为模型，为微生物多样性提供一种新的方法。该研究计划涉及数据库分析和实地研究，将在不同尺度（大陆、区域和地方）进行开发。和生态系统（湖泊、河流和池塘），利用我关于加拿大湖泊浮游动物群落的独特数据库，以及对魁北克南部圣劳伦斯河、城郊湖泊和城市池塘的实地研究，我们将实现研究目标。检查： 1. 纬度温度梯度如何决定加拿大大陆尺度的甲壳类浮游动物的分类、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如何调节北方湖区浮游动物多样性和群落结构？ 3. 沉水植被结构复杂性如何影响河流湖泊浮游动物物种丰富度、群落结构和功能多样性？ 4. 浮游动物生物多样性如何在城郊和城市景观的分类群和功能群以及生态系统之间分布？我们的首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 人员、3 名博士人员、3 名硕士人员、2 名硕士人员和至少 3 名人员。我将为本科生提供理论生态学、浮游动物生态学、空间建模、宏观生态学、生物多样性、系统发育、功能特征和城市生态学方面的培训。加拿大浮游动物的物种和性状分布图，ii) 加拿大浮游动物分类、功能和系统发育多样性指标的完整数据库，iii) 跨尺度不同来源淡水浮游动物的元数据，将浮游动物结构与环境条件联系起来，iv) 高等科学论文优质科学期刊，v) 用于分析淡水中浮游动物功能群的新成像系统应用，vi) 用于评估生态完整性和保护生物多样性的生物评估工具最后，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，作为我对浮游动物生态学的长期研究的遗产。总体而言，我的研究计划将提供更好的理解。构造淡水中微生物生命并有助于保护水生生态系统的机制。
