  abstract = {{B}y burrowing galleries and producing casts, earthworms are constantly changing the structure and properties of the soils in which they are living. {T}hese changes modify the costs and benefits for earthworms to stay in the environment they modify. {I}n this paper, we measured experimentally how dispersal behaviour of endogeic and anecic earthworms responds to the cumulative changes they made in soil characteristics. {T}he influence of earthworm activities on dispersal was studied in standardised mesocosms by comparing the influence of soils modified or not modified by earthworm activities on earthworm dispersal rates. {T}he cumulative use of the soil by the earthworms strongly modified soil physical properties. {T}he height of the soil decreased over time and the amount of aggregates smaller than 2 mm decreased in contrast to aggregates larger than 5 mm that increased. {W}e found that: (i) earthworm activities significantly modified soil physical properties (such as bulk density, soil strength and soil aggregation) and decreased significantly the dispersal rates of the endogeic species, whatever the species that modified the soil; (ii) the decreasing in the dispersal proportion of the endogeic species suggests that the cost of engineering activities may be higher than the one of dispersal; (iii) the dispersal of the anecic species appeared to be not influenced by its own activities (intra-specific influences) or by the activities of the endogeic species (inter-specific influences). {O}verall these results suggest that the endogeic species is involved in a process of niche construction, which evolved jointly with its dispersal strategy.},
