Seagrasses provide a paramount habitat for numerous creatures that find food and shelter (structure) within seagrass canopies. Disentangling the role of ‘food’ versus ‘structure’ as drivers of faunal colonization, however, remains unresolved, while the effect of seagrass structural variation as drivers of faunal colonization is also mostly unknown. In a set of experiments using artificial seagrass units (ASUs), performed in Western Australia (canopies of the seagrasses Amphibolis griffithii and Posidonia sinuosa) and at home (Cymodocea nodosa at our beloved Risco Verde at Gran Canaria), I had the opportunity to test for these models together with a couple of colleagues.
