From: Trophic level drives the host microbiome of soil invertebrates at a continental scale
Linear regression revealed the relationships between soil fauna trophic level (δ 15N value) and microbial diversity (a) and predicted microbial functional diversity (b). Violin plots showed unique bacterial taxa in different soil fauna microbiomes by filtering all species found in soil microbiome from the faunal microbiome in different types of animals (c) and in different trophic level of animals (d). By “unique,” we mean species which were present in the microbiome of a given soil invertebrate, but were not detected in any soil samples. The “TL” indicated the trophic level of soil fauna based on natural 15N fractionation of animal body tissue
