Fig. 3From: Distinct patterns of distribution, community assembly and cross-domain co-occurrence of planktonic archaea in four major estuaries of ChinaPrincipal coordinate analysis (PCoA) based on Bray-Curtis dissimilarity showing the variation in archaeal community composition. The plots were color-mapped by estuary (A), season (B), and station (C), respectively. Three WYE_L samples, three WYE_M samples, and all WP_L samples were excluded due to low read counts. Refer to Fig. 1 for the meanings of the letters in above station IDsBack to article page
