Decapods abundance, habitat, landscape, and geographical attributes in the NW Mediterranean Posidonia oceanica seagrass meadows [Dataset]

This dataset presents the decapod species and abundance, along with the habitat (detached seagrass leaves, fine fraction of detritus, detrital macroalgae, organic matter in sediments, seagrass shoot density and height of unburried rhizomes), landscape (landscape configuration) and geographical attributes (inlet aperture and confinement) in Posidonia oceanica seagrass meadows in 5 localities accross the NW Mediterranean sea. We found that geographical level attributes (i.e., inlet aperture, confinement) affected the most the decapod assemblages, while we only found a modest contribution from habitat (e.g., detritus biomass, sediment organic matter) and landscape attributes (e.g. fragmentation). We suggest that decapod assemblages are driven by the interaction of multiple processes occurring at different scales and other highly stochastic phenomena such as larval dispersion and recruitment
