Fig. 4From: Rock substrate rather than black stain alterations drives microbial community structure in the passage of Lascaux CaveNon-metric multidimensional scaling (NMDS) analysis of microbial community structure in the passage according to time, mineral substrate and stain presence. Results are shown for bacteria (a), micro-eukaryotes (b), and fungi (c), and ellipses (95% confidence intervals) indicate the different mineral substratesBack to article page
