The non-native slipper limpet Crepidula fornicata (Linnaeus, 1758) has proliferated in the Bay of Brest during the 90s. This suspension-feeding gastropod has become a dominant species both in terms of density (&gt; 2000 ind.m-2) and biomass (127 000 t fresh weight in 2000). C. fornicata is also an ecosystem engineer that modifies its habitat by the presence of its own shell (autogenic engineering) and by biodeposition of faeces and pseudo-faeces (allogenic engineering). Here, we tested the effects of C. fornicata on the colonized communities’ structural and functional diversity by distinguishing his auto- and allogenic engineering effects. One way these changes were studied along a gradient characterized by the total weight of slipper limpet (dead and...
