| Mobility / Life stage (?) |

| Salinity tolerance range (?) | Venice system: 5. α-Mesohaline [10-18psu] 6. Polymixohaline [18-30psu] 7. Euhaline [30-40psu] References: Bolton, J. J. 1979.

| Habitat modifying ability potential (?) | Autogenic ecosystem engineers References: Miller, S. L., Wilce, R. T. 2024. Grazing of free-living Pylaiella littoralis by the amphipod Gammarus tigrinus. Botanica Marina, 67(1), pp. 11-14. Comments: Also it is an important specie, because the amphipod Gammarus tigrinus is found within the floating drifts of algae. Gut contents confirmed that G. tigrinus consumed P. littoralis. |
| Toxicity / Life stage (?) | Not relevant |
| Bioaccumulation association (?) | Anthropogenic chemical compounds References: Carrilho, E. N. V., Gilbert, T. R. 2000. Assessing metal sorption on the marine alga Pilayella littoralis. Journal of Environmental Monitoring, 2(5), pp. 410-415. |
| Known human health impact? | Known References: Ye, B. R., Kim, J., Kim, M. S., Jang, J., Oh, C., Kang, D. H., ... Heo, S. J. 2013. Induction of apoptosis by the tropical seaweed Pylaiella littoralis in HT-29 cells via the mitochondrial and MAPK pathways. Ocean science journal, 48, pp. 339-348. Comments: P. littoralis extract might be potential candidate agents for the treatment of human colorectal cancer. |
| Known economic impact? | Not known Comments: Not available. |
| Known measurable environmental impact? | Known References: Råberg, S., Berger-Jönsson, R., Björn, A., Granéli, E., Kautsky, L. 2005. Effects of Pilayella littoralis on Fucus vesiculosus recruitment: implications for community composition. Marine Ecology Progress Series, 289, pp. 131-139. Comments: P. littoralis reduced the attachment rate of F. vesiculosus during the initial 12 h, while higher concentrations of exudates negatively affected germination and rhizoid development. |
