Table 5. Selection gradients of trait plasticities in response to temperature in Trifolium montanum, Ranunculus bulbosus and Briza media.

	T. montanum		R. bulbosus		B. media
	Total biomass	Number of flowers	Total biomass	Number of flowers	Above ground biomass
Growth rate	0.500	0.455	0.064	0.258	0.366
SLA	0.423	0.541	−1.380	−0.418	−0.577
Above-ground/total biomass	−0.497	−0.189	−1.334	−0.450	–
Budding start	0.289	0.480	−0.171	0.315	–
Flowering start	0.307	0.380	0.039	1.156	–

Selection gradients are expressed as standardized regression coefficients. All values are based on population means. Fitness measures are total biomass and number of flowers (T. montanum, R. bulbosus) and above ground biomass (B. media). Non of the selection gradients was significant.
