Image feature variation at the assemblage and species levels along an elevational gradient. Within-assemblage-level image feature variation (TIC/IR) in relation to a elevation, b temperature and c precipitation. TIC/IR is the ratio of community/assemblage-wide variance (Individual within-community/assemblage) to total variance in the regional pool (individual within-region), assessed at the individual level. Smaller within-assemblage-level variation suggests stronger environmental filtering effect on the trait20,21. The similarity of image features between species at each assemblage, TIP/IC, in relation to d elevation, e temperature and f precipitation. TIP/IC is the ratio of within-population variance (individual within-population) to total within-community/assemblage variance (individual within-community/assemblage). A higher TIP/IC ratio suggests less competition among species of the same assemblage. The grey solid and dashed lines represent significant and non-significant relationships, respectively. Warmer colours correspond to lower elevations, and cooler colours to higher elevations. Source data are provided as a Source Data file
