An increase in soil tillage intensity increasedthe proportion of 50–100 mm long earthworms at the expenseof smaller (20–50 mm) and larger (>100 mm) earthworms, andfavored those with a supple epithelium and simple typhlosolis.Although not always significant (overlapping confidence inter-vals), results tended to show a shift from smaller (1–2 mm)to intermediate-sized (2–4 mm) cocoons with increased tillage.Effects of tillage types were contradictory between trials for CWMbody mass/length ratio for the class 1–7 and 7–15 mm g−1. Decreasein soil tillage intensity increased the proportion of earthworms witha body mass/length ratio higher than 15 mm g−1.Results of CWM vertical distribution showed that, on every trial,an increase in tillage intensity led to a decrease in the proportionof earthworms living (i) in the upper soil layer (0–5 cm depth) and(ii) at more than 20 cm depth. Consequently, it favored earthwormsliving between 5 and 20 cm depth. Concerning carbon preferences,the trends of the two first classes (
