The contrasting competitive environments that populations of a species face across their range can create mosaics of local adaptation. Locally adapted populations may differ in their responses to climate change when the traits selected by their new environment are correlated with those selected by the historical competitive environment.
I will test these ideas using a combination of greenhouse experiments and mathematical models.
In a first greenhouse experiment, I will estimate the relative fecundity of 15 genotypes of Arabidopsis thaliana when growing in competition with different species.
