« Microevolution of trees and climate change »
Séminaire assuré par Antoine Krémer - UMR BioGeCo
Résumé :
A long-standing question and nowadays recurrent concern is the pace of microevolution of trees in response to on-going climate change. While most temperate tree populations are in place since several millenia no genetic diachronic approach allowed so far to grasp the time span needed to achieve adaptation to climate. I will review recent studies assessing temporal genetic changes in European oaks and address the following questions :
- What is the pace of microevolution at contemporary time scales ?
- What is the mode and direction of microevolution ?
- What are the drivers of microevolution in extant ecological settings ?
- Are there limits and constraints to ongoing microevolution ?
