报告人简介：
Belinda E. Medlyn is a Distinguished Professor at the Hawkesbury Institute for the Environment, Western Sydney University (Australia), with decades of work in ecological environment and plant science—internationally renowned for groundbreaking research on atmospheric CO₂-ecosystem interactions and plant physiological modeling. She holds a 1989 First-Class Honours BSc (Mathematics) from the University of Adelaide and a 1996 PhD from the University of New South Wales, having previously worked at institutions like the University of Edinburgh (UK), INRA (France), and Macquarie University (Australia); since 2015, she has served at Western Sydney University (Professor, Theme Leader of Ecosystem Function and Integration) and became Distinguished Professor in 2019. A key researcher in atmospheric CO₂’s impacts on plants/ecosystems and ecosystem modeling, she has over 200 high-impact papers and 7 book chapters, with honors including Clarivate Highly Cited Researcher (2018–2024), 2022 Ralph Slatyer Medal, 2023 Australian Academy of Science Fellowship, 2024 University of Barcelona Honorary Doctorate, and ARC Georgina Sweet Laureate Fellowship. She also edits New Phytologist, sits on Global Change Biology’s Editorial Advisory Board, chairs TERN’s Scientific Advisory Board (since 2021), and joins the Land Life Company’s Scientific Advisory Board and Oceania Ecological Forecasting Initiative Committee (since 2022) to advance global ecological research strategy.
报告内容简介：
The terrestrial biosphere is currently performing an ecosystem service worth trillions of dollars: over the last decade it has soaked up approximately 29% of anthropogenic CO2 emissions. However, the capacity of terrestrial ecosystems to continue taking up excess CO2 remains uncertain. Current Earth System Models project a continued sink for the rest of the century, but these projections may be too optimistic, particularly if we are over-estimating the fertilising effect of rising CO2 or under-estimating the negative impacts of increasing temperatures on terrestrial vegetation function. In this talk I will review the ways that vegetation responses to global change are currently embedded in process-based models, with a focus on the effects of rising CO2, warming and drought. I will discuss how evidence-based methods including model-data intercomparison, data assimilation and meta-analysis are driving advances in the predictive capacity of models, and I will outline what I see as the key research needs to deliver increased confidence in model projections of the terrestrial carbon cycle.
