Table 3 Results of the Generalized Linear Models (GLM) testing for significant effects of region (Alta Guajira, Media Guajira, San Andrés, Tayrona, Cartagena) on seagrass soil dry bulk density (g cm−3), soil organic carbon content (%), soil organic matter content (%), soil organic carbon stocks (Mg Corg ha−1 in 1-m thick) , δ13C (‰), and content of sediment grain-sizes < 0.016 mm, > 0.0.016 < 0.125 mm and > 0.5 mm (%) in the Colombian Caribbean.
