Intertidal macrobenthic seagrass biodiversity along a lagoonal confinement gradient

Abundance of macrobenthic morphotaxa at 4 intertidal seagrass sites (3 stations per site) along the confinement gradient of the Rainbow Channel in the leaky coastal lagoon of Moreton Bay, Queensland Australia. These display relative uniformity of assemblage abundance, biodiversity and composition along a gradient displaying a tenfold change in water residence time, and suggest that seagrass faunas do not conform to confinement gradients.
