Fig. 3From: Effect of room temperature transport vials on DNA quality and phylogenetic composition of faecal microbiota of elderly adults and infantsElderly subjects have higher diversity than infant subjects and are less variable after storage. a Shannon diversity of infant and elderly samples. b Shannon diversity values after storage across infant and elderly subject samples combined. c Higher variabilty of infant subjects demonstrated by increase in the absolute Spearman distances between samples. (i–iii) elderly samples and (iii–vi) infant samples. (i) and (iv) fresh vs 1 week’s storage; (ii) and (v) fresh vs 2 weeks’ storage; (iii) and (vi) 1 week’s storage vs 2 weeks’ storageBack to article page
