Table 1 Comparisons among weighted reconstructions (WR), non-trees reconstructions (NTR) and observed climates from Zhang et al. 2015. MAP, MAT, MTWA and MTCO are the same as in Fig. 1. CoIn = Coexistence interval, Obs. = Observed climate. Only 32 samples (out of the original 44 samples) satisfying the criterion of having more than 5 non-arboreal pollen, and shrub taxa represented at > 1% are used to conduct the climate reconstruction
