Taxonomic and beta diversity in the sediment zones. (1) Heat map of the 20 most abundant genera for each sediment zone in the coastal (A) and inland (B) sinkholes, the columns represent sediment sample, rows depict genera. Low abundance (yellow), medium abundance (orange) and high abundance (red). (2) Beta diversity analysis of the sediment samples. Non-metric multidimensional scaling (nMDS) plot based on the Bray–Curtis distance of 21,432 (C, Coastal sinkhole) and 8204 (D, Inland sinkhole) reads per sample.
