Fig. 3: Mangrove carbon (C) and the nature of soil organic matter between different soil depths.
From: The nature of soil blue carbon varies across mangrove geomorphic settings
Carbon and lignin content (VSC) of the soil (a, b), mineral-associated organic matter (MAOM) in soil (c), and MAOM normalized by soil carbon (d) between soil depths. Different capital letters indicate significant differences (p < 0.05), same letters indicate no statistical difference. Kruskal–Wallis tests were used. Heavy bars indicate sample medians; box ends indicate upper and lower quartiles; whiskers extend from the hinges to the largest and smallest values, respectively, which is no further from the hinges than 1.5 times the sample interquartile range. Circles indicate individual measurements, with vertical jitter to reduce overwriting.
