  abstract = {{D}espite the well-known potential of earthworms to modify soil macroporosity , water infiltration through their burrowing activities, it is still difficult to predict which species are more effective in increasing water infiltration. {W}e thus investigated the relationships between soil water infiltration, burrow network properties, morphology and anatomy of a diversity of earthworm species. {W}e sampled 23 earthworm species in northern {V}ietnam and measured 16 morpho-anatomical traits a priori linked to their feeding, vertical distribution or burrowing behaviour. {O}ne individual was then incubated in a repacked soil core for four weeks under laboratory conditions, each in four replicates. {A}fter incubation, burrow network properties were assessed using {X}-ray computed tomography , soil saturated hydraulic conductivity was measured using the falling head method. {W}e found large differences among species belonging to similar or different ecological categories in their effect on soil saturated hydraulic conductivity. {W}e observed neutral to positive effects with an increase of up to 30-fold compared to cores without earthworms. {T}he effect of earthworms on soil hydraulic conductivity was well pre-dicted by burrow network properties (volume and continuity of burrows) or morpho-anatomical traits (body weight, circular and longitudinal muscles thickness) using the random forest regression models ({R}2 > 0.95 in both cases). {E}arthworms with a large body weight and circular and longitudinal muscle thicknesses have the highest probability of increasing soil saturated hydraulic conductivity compared to other species. {I}n addition, we showed from the coinertia analysis that body weight and circular and longitudinal muscle thickness were positively associated with the volume and continuity of burrows. {O}ur findings therefore illustrate the power of employing a trait-based approach to predict the effect of non-{L}umbricidae earthworms on water infiltration in comparison to the classical ecological category approach. {S}uch trait information could be used to prioritize practices that favour the expression of more desirable earthworm traits to increase soil water infiltration.},
