Data from Parasites or commensals Spatial variability in symbiont-host patterns and defining ecological interactions from observation-al data.pdf

The solitary ascidian Phallusia nigra was collected from three reefs near El Gouna on the Egyptian Red Sea coast. Ascidians were dissected and their associated symbionts quantified. By comparing spatial variability in symbiont community to host condition index, the nature of the relation between host and symbiont was explored.
