Fig. 3: Box plots showing soil Corg stocks by seagrass genus (colors), nested within functional group.
From: Global seagrass carbon stock variability and emissions from seagrass loss
Box plot elements are defined as in Fig. 1. Note the logarithmic y-axis. Also shown are letters indicating differences (α = 0.001) between functional groups (Kruskal–Wallis, Dunn’s post hoc56), median carbon stocks (x͂), coefficients of variation (cv), and sample size (n) for functional groups. Horizontal lines indicate the IPCC Tier 1 estimate26 (dashed) and our new database median (solid). Note that Zosteraceae were recently revised to encompass multiple genera, which is not reflected in this study57. Two very low carbon stocks of the “unvegetated” group were excluded for display purposes.
