Fig. 5: Marine prokaryotic genomes are larger in the polar ocean than in the tropical low-latitude ocean.
From: Abiotic selection of microbial genome size in the global ocean

Boxplots show estimated median average genome size (AGS) as horizontal lines and interquartile ranges as boxes (whiskers extend to a maximum of 1.5 times the interquartile range). Mean values are shown as white colored diamonds. Values at the top indicate the adjusted significant P values of the unpaired two-sided Wilcoxon test with Benjamini-Hochberg correction. Values in parenthesis show the number of metagenomes. Source data are provided as a Source Data file.
