Figure 4: Major clade global-scale abundances and model predictions.
From: Biogeography and habitat modelling of high-alpine bacteria
The relative abundance of Colorado's four major clades across high-alpine soils at a global scale (Acido, Acidobacteria G4; Rhizo, Rhizobiales; Rhodo, Rhodospirillales; and Sapro, Saprospirales; a, Rocky Mountains; b, Alaska Range; c, Himalayas; and d, Andes). Actual relative abundance: open bars; predictive habitat model relative abundances: shaded bars; error bars represent standard error; *indicates nonsignificant difference between actual and predicted (t-test, n = 6, P>0.05). Ordinary Least Squares (OLS) predictive habitat models using a restricted parameter set (see model parameters, Table 2). Acidobacteria G4 and Saprospirales had significant correlation between residuals (predicted relative abundance−actual relative abundance) and environmental variables, and are error corrected using OLS to predict residual error. Sanger relative abundances were rescaled because of the previously described biases in Sanger versus pyrosequencing14,41.
