Extended Data Figure 5: Changes of apparent temperature sensitivity of leaf unfolding determined by different methods.
From: Declining global warming effects on the phenology of spring leaf unfolding
a–c, The ST were analysed in two 10-year periods (a), were calculated using the reduced major axis (RMA) regression (b), or were calculated based on another climate forcing data set (CRU-NCEP v5, c). Species-specific ST and s.d. (in brackets) across all sites in three periods and the difference between the two study periods are provided. The colour scale indicates the magnitude of ST. The number under the species name is the number of sites. The histograms show the distribution of ST across all species and sites in two different periods and the mean ST and s.d. (in brackets). The asterisk indicates a significant difference of ST between the two periods at P < 0.05.
