Brown sea coconut with yellow fibers between the two lobes of the coconut, going from the upper to the third of the length of the coconut. The coconut lays on a table.
Boxplots showing 16S rRNA gene copy number (y-axis) per host cell (left panel) for stomach, gut, hepatopancreas, ovotestis, and whole snail, or per microliter (right panel) for hemolymph, tray water, and tank water. Biomphalaria alexandrina is shown in orange, B. glabrata in green, with boxplots of each species displayed side by side for each sample type.
Two UpSet plots: the top one for Biomphalaria alexandrina, the bottom for Biomphalaria glabrata. Each plot is divided into three sections: the bottom left shows a horizontal barplot representing the number of amplicon sequence variants (ASVs) per sample type, the top right shows a vertical barplot representing the number of ASVs per intersction, and the bottom right is a dot plot displaying the specific intersections between sample types. Dot plot start with sample-type specific set (no intersection) then continue with increasing intersection between sample types to end with set that include all sample types. Sample type: hemolymph, stomach, gut, hepatopancreas, ovotestis, whole snail, tray water, tank water.
Taxonomic figure divided in three sections: taxonomic plot for Biomphalaria alexandrina (top), taxonomic plot for B. glabrata (middle), and a legend displayin phylum names (bottom). Taxonomic plots show the relative proportion (y axis) for each sample type (hemolymph, stomach, gut, hepatopancreas, ovotestis, whole snail, tray water, tank water).
Four distance trees showing relationships between sample types (hemolymph, stomach, gut, hepatopancreas, ovotestis, whole snail, tray water, tank water). The two trees on the left display Unweighted and Weighted UniFrac distances for Biomphalaria alexandrina (Ba); the two on the right show the same for B. glabrata.
Boxplots showing observed richness (y axis) by sample types (hemolymph, stomach, gut, hepatopancreas, ovotestis, whole snail, tray water, tank water). Biomphalaria alexandrina is in orange and B. glabrata in green, with boxplots of each species being side by side for each sample type.
Experimental plan showing tanks of Biomphalaria glabrata and B. alexandrina snails, from which 7 snails per tank were sampled, fasted overnight, and then either dissected to obtain hemolymph, stomach, gut, hepatopancreas, and ovotestis, or snap-frozen in liquid nitrogen and ground into powder. Tank and fasting tray water were also sampled. Samples were used for DNA extractions.
