Abstract Soil organic matter (SOM) transformation processes are regulated by the activities of plants, microbes, and fauna. Compared with plants effects soil fauna less understood because their high taxonomic functional diversity, mix direct indirect effect mechanisms. Trait‐based approaches offer a generic perspective to quantify mechanistic relationships between SOM transformations, including decomposition, translocation, stabilisation carbon. Yet, at present, we lack consensus concerning relevant key traits (i.e. those affecting ecosystem functioning). Here, address this knowledge gap focusing on transformations. Based existing literature, identify linked universally applicable across taxa types, discuss process‐trait links. We define eight that directly affected fauna: (i) litter mass loss, (ii) fragmentation, (iii) aggregation in faeces, (iv) mineral particles, (v) decomposition (vi) (vii) pore space creation maintenance (viii) stabilisation. link these general classified into four categories: (a) food selection ingestion, (b), digestion excretion, (c) mobility, (d) body metabolic rate. also propose proxies when trait measurements laborious. The proposed links need be validated targeted experiments. urge researchers obtain quantitative experimental data, together approaches, integratively contributions functioning.
