Small-scale patches of detritus as habitat for invertebrates within a Zostera noltei meadow

Seagrass detritus can attract numerous invertebrates as it provides food and substrate within the meadow or in adjacent environments. Nonetheless, several factors could modify invertebrate response to this habitat. In study, we tested if epifaunal colonisation of Zostera noltei was related availability rather than whether colonising assemblages were similar according structural complexity. Litterbags filled with natural artificial deployed an eelgrass a Mediterranean coastal lagoon (Thau lagoon, France). Colonisation appeared be driven by presence detritus, substrate, but more individuals empty bags, used controls. There also no differences habitat These findings show that acting faunal magnet, plays important role maintaining biodiversity, epifauna is critical trophic link between primary producers consumers.
