From: Environmental drivers of viral community composition in Antarctic soils identified by viromics
Environmental drivers found by multivariate correlation analysis. Identified drivers were altitude (alt.), pH, calcium (ex; exchangeable cations), and % Ca. Top: hierarchical agglomerative clustering based on the Euclidean distance matrix using identified environmental drivers only. Untransformed values of the factors were normalized prior to analysis. The group average mode was used, and simprof was performed to identify two distinct subgroups indicated with dashed lines. Bottom: table with individual values of environmental drivers for each subgroup and sample
