CREAF Talk with Nicolas Martin St-Paul - "A plant hydraulic perspective on the impact of climate change on forests and strategies for adaptation"

Thursday, October 5, 2023 - From 12 to 1 pm

TITLE: "A plant hydraulic perspective on the impact of climate change on forests and strategies for adaptation"

DATE: Thursday, 5th October 2023.

TIME & FORMAT: form 12 to 1pm CET - In-person and online.

Seminars will combine in-person and online formats (CREAF, Sala Graus II, Universitat Autònoma de Barcelona, Spain) but in all cases, talks will be always streamed (not recorded), so they can be followed online.

HOW TO CONNECT: direct link to Nicholas Martin St-Paul's conference.


Forests are profoundly impacted by increased atmospheric and soil drought due to climate change, making it urgent to develop relevant adaptation strategies. In this presentation, Nicholas Martin St-Paul will show how the field of plant hydraulics provide a conceptual and methodological foundation for understanding and quantifying the impacts of climate change on forest disturbances risks and evaluating potential strategies for adaptation. He will present the plant hydraulic model SurEau, and how it can be used as hub to integrate climate, soil, remote sensing and plant hydraulic traits data and to provide an integrative and physiologically informed risk framework. He will show how this framework can be used to identify the most critical plant hydraulic traits and environmental parameters driving the risk of hydraulic failure. Finally, he will show how such a modelling framework can help to asses inter and intraspecific variability in drought resistance and evaluate the potential of some practices, such as mixed species plantations, in mitigating the risk of hydraulic failure.


Researcher at INRAE Avignon, France, his work focuses on how trees and forests response to drought and heatwaves. He is focused on the physiological mechanisms involved in water transport (plant hydraulic), to understand and model plant hydraulic failure and plant desiccation. This is why he uses the plant hydraulic theory as a hub to integrate various discipline and various sources of data and understand broader scales ecological patterns (disturbances, biogeography, species coexistence, ecosystems functions, etc).  

He develops the plant hydraulic model SurEau and uses it to integrate such data including, traits (from lab measurements), forestry data (inventory), soil, remote-sensing data and climate data into mechanistic model to propose an integrative and reliable risk framework. Nicholas Martin St-Paul's aims to use this knowledge to evaluate mechanistically the future of forest in terms of climate change impacts and forest adaptation possibilities.
