| The structural complexity of Agarophyton vermiculophyllum suppported greater diversity of invertebrates, and a greater abundance of gastropods than the native Ulva rigida. However, the native U. rigida supported higher abundances of both native, cryptogenic, and introduced taxa, the latter including Ficopomatus enigmaticus and Musculista senhousia (Munari et al. 2015). Sfriso et al. (2019) argued that Agarophyton vermiculophyllum has net benefits in Venice Lagoon, by reducing anoxia through photosynthesis and providing habitat in turbid, eutrophic water where native vegetation has been list, | ||
