  abstract = {{T}he aim of this study was to investigate the burrowing activity of two earthworm species: the endogeic {D}rawida sinica and one undescribed {A}mynthas species incubated in{V}ertisol and {U}ltisol presenting different soil organic {C} content. {B}ecause of their contrasting feeding behaviours, we hypothesised that soil type would have a bigger influence on the burrowing activity of the endogeic than the anecic species. {R}epacked soil columns inoculated with earthworms for 30 days were scanned using {X}-ray tomography and the compiled images used to characterise the burrow systems. {A}fter scanning, the saturated hydraulic conductivity ({K}-sat) was also measured. {T}he {A}mynthas species burrows were less numerous (30 vs. 180), more vertically oriented (57 vs. 37 degrees), more connected from the surface to the bottom of the columns (73 vs. 5 cm(3)) and had a higher global connectivity index (83 vs. 28%) than those of {D}. sinica. {T}he {K}-sat was threefold faster in columns incubated with {A}mynthas and was linked to the volume of percolating burrows ({R}-2 = 0.81). {T}he soil type did not influence {A}mynthas burrow characteristics. {I}n contrast, there were 30% more {D}. sinica burrows in the {V}ertisol than in the {U}ltisol while other burrow characteristics were not affected. {T}his result suggests that these burrows were more refilled with casts leading to shorter and discontinuous burrows. {T}he {K}-sat was negatively related to the number of burrows ({R}-2 = 0.44) but was not statistically different between the {V}ertisol and the {U}ltisol, suggesting a constant impact of this species on the {K}-sat. {W}e found that a decrease in the amount of soil organic {C} by 50% had only a small influence on earthworm burrowing activity and no effect on the {K}-sat.},
