Figure 3:

Stacked barplot of the relative abundance of bacteria at the phylum level associated with differing numbers of hand-picked Trichodorus primitivus nematodes and soil (all fields combined) from which the nematodes were extracted.

Figure 4:

Log2 fold change in bacterial genera found to be differentially abundant (all fields combined). Values <0 are enriched in soil, and values >0 are enriched in nematodes.
