Figure 4. Density plot of the EIVE Temperature distribution with highlighted sectors based on percentile thresholds. The graph illustrates temperature density as a percentage, with the 25th percentile (blue dashed line) and 75th percentile (red dashed line) demarcating the lower, middle, and upper temperature ranges. The shaded areas represent the proportion of EIVE T falling within these ranges, with colors indicating different density levels: light yellow for EIVE T below the 25th percentile, orange for EIVE T between the 25th and 75th percentiles, and dark orange for EIVE T above the 75th percentile (A). The point chart shows the distribution of alien plant taxa along the elevation gradient, using EIVE T data for ecological classification. Each colored dot represents the elevation at which the alien plant taxon was recorded, with each color corresponding to a specific EIVE T class (B). |
