A fresh approach to biodiversity patterns of freshwater zooplancton across scales and ecosystems

在加拿大，湖泊和河流是景观的主要特征，但在食物网基础上的淡水微生物多样性的知识仍处于起步阶段。该研究计划将为研究微生物多样性提供一种新的途径，以淡水浮游动物为模型群落，并将群落生态学、功能性状和系统发育生物学整合为启发式框架。这项研究计划包括数据库分析和实地研究。四个项目将跨越尺度（大陆、区域和地方）和生态系统（湖泊、河流和池塘），使用我在加拿大湖泊中独特的浮游动物群落数据库，以及在圣劳伦斯河、城市周边湖泊和城市池塘进行实地研究。为了解决研究目标，我们将检查：****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、人为干扰和局部环境过滤对北方湖泊浮游动物多样性和群落结构的调节作用[j]。3 .水淹植被结构复杂性对河湖浮游动物物种丰富度、群落结构和功能多样性的影响？浮游动物的生物多样性是如何在城市周边和城市景观的分类群、功能群和生态系统中分布的？*****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。通过提出的研究项目，我将培养2名PDF， 3名博士，3名硕士，2名硕士，至少3名本科生。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、系统发育、功能性状和城市生态学等方面的培训。该研究将产生以下几个可交付成果和产品：i)加拿大浮游动物的物种和性状分布图，ii)加拿大浮游动物的分类、功能和系统发育多样性指标的完整数据库，iii)不同来源的淡水浮游动物的元数据，将浮游动物的结构与环境条件联系起来，iv)高质量科学期刊上的科学论文，v)用于分析淡水浮游动物功能群的新成像系统应用，6)城市景观中水生生物群落生态完整性和生物多样性保护评价的生物评价工具。最后，我想编辑一本关于加拿大淡水桡足类的系统、分类和分布的书，作为我长期研究浮游动物生态学的遗产。总的来说，我的研究项目将更好地理解淡水中微生物生命结构的机制，并为水生生态系统的保护做出贡献

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.***
