Fig. 4: Bacterial diversity and its spatial distribution from the air to 4 m depth in the ice.
From: Microbial biogeography along a 2578 km transect on the East Antarctic Plateau
A Bacterial diversity profile after 16S rRNA gene sequence analysis at the phylum level in the three air (AN, AM, AS) and three snow/ice cores (DN, DM, DS) from 1, 0-1 m; 2, 1-2 m; 3, 2-3; 4, 3-4 m depth. B Spatial distribution and relative abundances (%) of bacterial ASVs shared between the air and snow/ice core samples. Relative abundances of ASVs were calculated over the total bacterial community in each sample. (P) Proteobacteria, (F) Firmicutes and (A) Actinobacteriota. Sample code ID is as in A. C Non-metric multidimensional scaling (NMDS) ordination based on Bray-Curtis dissimilarity distances of ASV abundances from air (triangles) and snow/ice (dots) samples from North (red), Middle (green) and South (blue) sampling sites (see text for explanation).
