From: Microbial communities from arid environments on a global scale. A systematic review
Community structure of arid soil bacteria varies with MAT and MAP. Vertical bars represent mean relative abundance (%) of each phylum in the samples from articles included in this systematic review. Bars indicate relative abundance coloured by bacterial phyla; a: Relative abundance (%) sorted according to mean annual temperature (MAT). b Relative abundance (%) sorted according to mean annual precipitation (MAP)
