Is spatial uniformity of soft-sediment biodiversity widespread and, if so, over what scales?

Spatial variation in the components of faunal assemblages, but spatial uni formity of their biodiversity metrics, as described in 2013 for a seagrass bed in an estuarine bay in the warmtemperate Indian Ocean, is probably widespread in marine environments, and not restricted to seagrass habitats. Her...
