Regression of fruit number (fitness) under elevated temperature on mean trait value and its plasticity. Plasticity was measured as the difference between elevated and control means, and represents the response to changes in the temperature of the same genotype. Analyses were done twice using flowering time (measured in days) and rosette diameter

	Flowering (days)			Rosette diameter (mm)
	b	t	P	b	t	P
Mean in elevated plots	−8.0 ± 6.8	1.2	0.237	10.1 ± 2.1	4.8	3.0 × 10−06
Plasticity	−40.9 ± 9.8	4.2	3.9 × 10−05	3.9 ± 2.4	1.6	0.102

Bold values indicate significant at P <0.05.
