| Description: |
International audience ; Traditionally, leaf litter has been recognized as the main driver of the soil food web, but more recently roots have been shown to play an important role in fuelling soil organisms. Root functional traits were shown to have direct effects on microbes and Nematoda, but many knowledge gaps remain such as the effects of root traits on Collembola. Here, in a microcosm experiment, we studied the tri‐trophic interactions between roots, microbes and Collembola in relation to 10 plant species individually. Eleven root traits were measured to test whether they have an influence on Collembola and microbe community structure and Collembola functional structure based on six traits. The interactions between microbes and Collembola were also tested. Our results show that plant species identity significantly influences the structure of Collembola communities, and this variation is primarily explained by root traits and microbial communities. Collembola feeding traits based on mandibular morphology were useful to identify top‐down control on microbial communities. Our study also suggests that root traits such as fine root length and root diameter modify Collembola–microbe interactions, hypothetically by modifying soil porosity. Overall, we obtained better results by looking at the whole system, rather than looking at bi‐trophic interactions. This illustrates the importance of a holistic approach when studying biotic interactions in soil ecosystems.

Il a été démontré que les traits fonctionnels racinaires ont un effet direct sur les microbes et les nématodes, mais plusieurs zones obscures demeurent, entre autres sur l'impact des racines sur les collemboles.
