  abstract = {{F}ree-living nematodes are key organisms that greatly enhance plant growth and nutrient uptake. {I}n contrast, plant-parasitic nematodes are considered a major pest group in agriculture. {T}he effect of nematodes, either positive or negative, on plant productivity depends on their ability to disperse in soils. {U}nderstanding the dispersal process of nematodes is therefore crucial but is still poorly documented. {T}he aim of this study was to examine the effects of the endogeic tropical earthworm {P}ontoscolex corethrurus on the horizontal dispersal of nematodes in {F}erralsols in {M}adagascar. {A} microcosm experiment was conducted under controlled laboratory conditions. {T}wo factors modulating dispersion were studied: (i) the earthworm density with three modalities (without, five or ten individuals) and (ii) the duration of the experiment with two modalities (four and eight weeks). {T}he results showed that {P}. corethrurus favored the horizontal dispersal of nematodes. {T}his is mainly a dispersal mechanism through the earthworm casts that they deposit in the soil or on the soil surface during their movements. {T}he total abundance of dispersed nematodes increased with the earthworm density and the duration of the experiment. {C}ephalobidae dominated the trophic structure of the dispersed nematodes, similar to the original populations. {H}owever, the original populations had a higher taxonomic diversity than the dispersed nematode communities. {T}hese results indicate that {P}. corethrurus, through dispersion, influences the spatial and temporal distribution, abundance and structure of nematode communities in the soil.},
