Temperature sensitivity of reproductive efforts in oaks.

Species	Temporal		Spatial
	MAcorns/Year	MAcorns/TAp-Ma	MAcorns/Alt100m	MAcorns/TAp-Ma
Q. petraea	19.82 [8.3, 31.3]	111.89 [63.1, 146.0]	−83.89 [−149.5, −18.3]	334.2 [175.6, 589.2]
Q. robur	14.07 [−1.7, 29.8]	72.66 [19.6, 120.5]	—	—

Slopes of the linear mixed-effect regression between acorn production in kilograms per hectare (M_Acorns) and year (temporal gradient, (M_Acorns/Year)), and for every 100 m increase in elevation (spatial gradient, M_Acorns/Alt_100m), and the mean temperature in April and May in °C (M_Acorns/T_Ap-Ma) in both studies. The 95% confidence intervals are indicated in square brackets. Reproduction in Quercus petraea was monitored in both studies, whereas Quercus robur was monitored in the temporal gradient study only. Significant correlations are indicated in bold.
