Abstract
Vegetation and underground structures are known to influence flood avoidance and flood resistance in invertebrates. In bimonthly-flooded European salt marshes, recent invasions by the nitrophilous grass <i>Elymus athericus</i> strongly modified usual habitat structure, notably by the production of a deep litter layer. Consequently, invaded habitats provide more interstitial spaces that may act as a refuge during flood events. By using both controlled and field designs, we tested whether invaded habitats may change the ability to resist flooding by the creation of new refuges during tides for a ground-living, predatory arthropod. The wolf spider <i>Arctosa fulvol...
