Dr. Elisa Stefaniak. "Modelling optimal plant carbon storage under stress"
Metsätieteiden talo 332/ https://helsinki.zoom.us/j/66176963105?pwd=QUk3Yzk1UDRLK0dQR1dxL1lHSXB4dz09 (passcode 908134)
Predicting how environmental stress modifies vegetation function involves understanding how plant tolerate stress. For example, plants store non-structural carbohydrates which provide them with energy and materials during stress and expedite post-stress recovery. However, storing carbon requires an a priori action that, while having positive effects on future survival during stress, may be detrimental in the short-term by re-directing carbon from other crucial processes such as growth. I explore this growth-storage trade-off by employing a range of modelling techniques to describe the response of the optimal storage utilisation trajectory. The three methods used: optimal control theory (OCT), gap model simulation and model predictive control (MPC), allow for the characterisation of an optimal trajectory during a single stress event (OCT), the investigation of the long-term success of alternative storage strategies in a community of plants under stochastic stress (gap model) and exploring the acclimation of carbon storage to a stochastic environment (MPC). The results from these modelling exercises identify candidate storage-related allocation traits that can potentially link carbon storage strategies with other observable plant traits and processes.

If you are interested in giving a presentation, don't hesitate to contact Jon Atherton and book your slot!

Zoom and/or Room 332 unless announced otherwise, Forest Sciences Building, 3rd floor, Viikki
The Wine & Science seminars provide a valuable channel of constructive criticism from a wide and multidisciplinary audience on your work. Anyone from a PhD student to a Professor can give a presentation. Wine Seminars are a great way to present ongoing work and discuss preliminary results so that the seminar has a chance to feedback on your work. Finalized studies can also be presented. The audience is usually composed of MSc and PhD students, postdocs and senior staff with diverse backgrounds, so it is good to prepare a few introductory slides.
Topics cover the measurement, characterization and modelling of physical and physiological ecosystem processes and their interactions with the environment and climate (very broad indeed!). If you doubt whether your subject fits in, don't hesitate to contact Jon Atherton.
Wine & Science seminars are a great chance to learn new things, interact with other research topics, and come up with new ideas, synergies and even collaborators! The series is also a great place for visiting scholars to give a talk.
