Reproductive type (?) | Asexual Sexual References: Hwang, I. K., Kim, H. S., Lee, W. J. 2005. Polymorphism in the brown alga Dictyota dichotoma (Dictyotales, Phaeophyceae) from Korea. Marine biology, 147, pp. 999-1015. Comments: D. dichotoma populations: the more common sexual cycle and the asexual cycle.Dictyota dichotoma is dioecious, reproduction taking place in the spring and summer. The sporophytes and the gametophytes are similar in morphology, and the reproductive organs appear on the thallus as small, dark-coloured spots. |

Salinity tolerance range (?) | Unknown |
Habitat modifying ability potential (?) | Autogenic ecosystem engineers |
Toxicity / Life stage (?) | Not relevant |
Bioaccumulation association (?) | Anthropogenic chemical compounds References: Laib, E., Leghouchi, E. 2012. Cd, Cr, Cu, Pb, and Zn concentrations in Ulva lactuca, Codium fragile, Jania rubens, and Dictyota dichotoma from Rabta Bay, Jijel (Algeria). Environmental monitoring and assessment, 184, pp. 1711-1718. Comments: The brown algae species (D. dichotoma) can be valuable indicator organisms due to their ability to accumulate cadmium, chromium, copper, lead, and zinc. |
Known human health impact? | Known References: El-Shaibany, A., Al-Habori, M., Al-Maqtari, T., Al-Mahbashi, H. 2020. The Yemeni brown algae Dictyota dichotoma exhibit high in vitro anticancer activity independent of its antioxidant capability. BioMed Research International, 2020(1), 2425693. Comments: Harmless. D. dichotoma exhibits a potential safe anticancer marine product. |
Known economic impact? | Known References: Imran, M., Badshah, S. L., Alves, J. L. F., da Silva, J. C. G., Iqbal, A. 2023. Pyrolysis of brown macroalgae Dictyota dichotoma and its thermokinetic analysis. Biomass Conversion and Biorefinery, pp. 1-11. Comments: Dictyota seaweed biomass as a promising feedstock for bioenergy generation, contributing to the development of the blue economy. |
Known measurable environmental impact? | Not known |
