Abstract Soil bacteria and fungi mediate terrestrial biogeochemical cycling, but we know relatively little about how trophic interactions influence their community composition, diversity, function. Specifically, it is unclear consumer populations affect the activity of microbial taxa they consume, therefore interaction those with other members community. Due to its extreme studying dynamics in soil a complex feat. Seeking address these challenges, performed microcosm‐based manipulation experiment determine impact common fungal‐feeding nematode ( Aphelenchus avenae ) on (e.g., C cycling parameters). Fungivory decreased fungal bacterial α‐diversity stimulated N possibly via cascading impacts fungivory communities. Our results present experimental evidence that are intimately linked diversity function, factors key understanding global patterns cycling.

Species interactions are key drivers of biodiversity and ecosystem stability. Current theoretical frameworks for understanding the role make many assumptions which unfortunately, do not always hold in natural, diverse communities. This mismatch extends to annual plants, a common model system studying coexistence, where typically averaged across environmental conditions transitive competitive hierarchies assumed dominate. We quantify interaction networks community wildflowers Western Australia natural shade gradient at local scales. Whilst competition dominated, intraspecific interspecific facilitation were widespread all categories. Interaction strengths directions varied substantially despite close spatial proximity similar levels species richness, with most interacting different ways under conditions. Contrary expectations, predominantly intransitive. These findings encourage us rethink how we conceive categorize mechanisms driving plant systems.
