Antarctic soil bacterial community beta-diversity. Principal Coordinate Analysis (PCoA) was calculated on the Hellinger-transformed bacterial community at the genus level where all samples (A) and only island samples (B) are colored as the respective ACBRs. ACBRs were plotted in the PCoA plot following envfit test (A). PERMANOVA pairwise comparisons (C) were performed only between ACBRs represented by at least 20 samples. PERMANOVA was performed on Bray–Curtis dissimilarity matrices calculated on the Hellinger-transformed bacterial community at the genus level (1000 permutations). All the reported pairwise comparisons are statistically significant (adjusted p < 0.01). ACBR 1: North-east Antarctic Peninsula; ACBR 3: North-west Antarctic Peninsula; ACBR 4: Central South Antarctic Peninsula; ACBR 6: Dronning Maud Land; ACBR 7: East Antarctica; ACBR 8: North Victoria Land; ACBR 9: South Victoria Land; ACBR 10: Transantarctic Mountains; ACBR 12: Marie Byrd Land; ACBR 16: Prince Charles Mountains.
