Figure 6
Map of collected fish gut microbiota and historical seawater microflora. The pie charts show the relative abundance of microbiota in collected adult grey mullet gut samples (yellow point) and seawater samples including 33 seawater samples published from four previous studies: Dong et al., 2013 (green points); Zhang et al., 2014 (red points); Zheng et al., 2016 (blue points), and Wu et al., 2017 (purple points). The colours in the pie chart present the relative abundance of different bacterial phyla, listed in top-left box, in each individual seawater sample or the grey mullet cryptic species. Name of fish groups and seawater samples are under their respective pie chart. NWP1, NWP2, and NWP3 indicate adults of three cryptic species of grey mullet M. cephalus in the Taiwan Strait. The map was created in GenGIS software58. Detailed information on seawater samples are provided in Supplementary Table 5.
