讲座简介：

In this talk I will discuss one of the oldest questions in plant ecology: how does plant (especially leaf) form and function vary along environmental gradients? Focusing on traits that are key targets for vegetation modelling, I will discuss (1) Plant traits and plant ecological strategies, (2) Climate and soil effects on traits, (3) Optimality theory for climate effects, and (4) How universal are trait–climate relationships across different situations?

主讲人简介：

Professor Ian J. Wright is a Distinguished Professor at the Hawkesbury Institute for the Environment, Western Sydney University, and a Chief Investigator at the ARC Centre of Excellence for Plant Success in Nature and Agriculture. He is best known for global-scale analysis of plant traits, mechanistic study of plant structure–function relationships, and applying economic concepts to plant ecology and evolution. He proposed the Leaf Economic Spectrum (LES), describing coordination in leaf carbon and nutrient investments and the rates and durations of photosynthetic returns; the related “least-cost theory” concerns co-optimisation of nitrogen and water costs for photosynthesis. Both provide a more robust theoretical basis for global vegetation productivity models. He is a Fellow of the Australian Academy of Science and a Highly Cited Researcher (2014–2021), with over 63,000 citations and an H-index of 93.
