报告人简介：
Prof. Marc Cadotte is currently a Professor of Biological Sciences at the University of Toronto-Scarborough where he also held the term-limited endowed TD Professor of Urban Forest Conservation and Biology chair (2013-2019). In 2020, he was elected Member of the College of New Scholars, Artists and Scientists, The Royal Society of Canada. He is also the Editor-in-Chief of Ecological Solutions and Evidence and Chair of Applied Ecology Resources, two new publication projects developed with the British Ecological Society and which provide a new communication paradigm for traversing the research-practice divide in ecology. He researches the links between biodiversity and ecosystem function, how to predict and control invasive species, and how environmental changes influences the delivery of ecosystem services. He has published more than 150 articles and has pioneered biodiversity measures that quantify species differences. Prof. Cadotte has accrued over 13,000 citations and has an H-index of 56 (according to Google Scholar), and is listed on Web of Science’s top 1% most cited scientists in environmental science since 2017.
报告内容简介:
Abstract: Human-caused change is altering biodiversity and ecosystem processes across spatial scales. Biodiversity is the foundation for the functioning of healthy ecosystems and for providing economic and other benefits to human wellbeing. Twenty years of experiments confirm such biodiversity-ecosystem function (BEF) relationships, but putting this research into real-world environmental change and management scenarios has been surprisingly limited. Environmental change drivers (hereafter referred to as stressors) can impact species differently, with positive, neutral, and negative impacts on their fitness, carrying capacity, interactions, and access to resources -and so predicting the impacts of multiple stressors on changes to biodiversity and ecosystem functioning can be complex. In this talk, I examine how biodiversity influences ecosystem functioning, and then focus on how stressors alter species contributions to function and the nature of the relationship between biodiversity and ecosystem functioning. I use theoretical models to examine how multiple stressors could impact BEF relationships, and then test this with experiments. I will then scale up these predictions to BEF patterns in different scenarios under anthropogenic stressors. I end off with how this research can provide insights and guidance to studying and managing biodiversity in cities.
