摘要: The green macroalga Ulva L. is well known as having an alternation of isomorphic biphases: gametophyte and sporophyte. However, examination the temporal in phase dominance has not been carried out. By inducing reproduction thallus samples laboratory, this study reports changes two phases sex ratios a natural population pertusa Kjellm. Seto Inland Sea, Japan, over period >3 years. results showed that occurred after 11–20 months; seasonal were observed population. ratio male female gametophytes remained ∼1:1 throughout investigated period, although skewed several collections.
