The importance of intraspecific variation for plant resilience under climate change
Course unit 1 | March 30th 8.00 - 10.00 am (UTC +2)
Course unit 2 | April 13th 8.00 - 10.00 am (UTC +2)Course objectives
Climate change is a major threat to plants worldwide. While much attention is paid to species variation in vulnerability to climate change, particularly in light of predicted shifts in species distributions and declines, intraspecific variation will also play a key role. In this seminar, we will discuss three dimensions of intraspecific variation relevant to climate change resilience in plants:
1) population variation due to local adaptation across heterogeneous environments;
2) phenotypic plasticity within individuals to changing environments within a plant's lifetime;
3) genetically regulated developmental variation (ontogeny) to predictable changes in environments through a plant's lifetime.
Strategies for quantifying these sources of variation in plant performance and functional traits will be discussed. Examples from my lab's research on drought and salinity tolerance in subtropical Pacific island plants will be used to illustrate these approaches.
