Fig. 4From: Mind the gut: genomic insights to population divergence and gut microbial composition of two marine keystone speciesComposition, diversity, and differentiation of A. tobianus and H. lanceolatus gut microbial communities. a Bar plot depicting the percentage of individuals with the occurrence of the bacterial phyla found in A. tobianus and H. lanceolatus guts. b Alpha diversity (Chao1 Index left, Shannon-Wiener Index right) increased significantly with decreasing salinity level (indicated as an arrow) in A. tobianus, while no clear trend is observed in H. lanceolatus. c Heat map of OTUs that changed significantly in relative abundance (%) as a function of sampling site at genus level (A. tobianus and H. lanceolatus combined)Back to article page
