Yellow Sea green tides have occurred in coastal China almost every year from 2007 to 2011. Ulva prolifera (Müller) J. Agardh has been identified as the causative macroalgal species. U. intestinalis, however, has been observed in the bloom areas, co-occurring with U. prolifera, but it has not been found to be causative. The Yellow Sea green tide has shown consistent phases of development that ma...

Antibacterial activities of the methanolic extracts Stypopodium schimperi (Kützing) Verlaque and Boudouresque, Halopteris filicina (Grateloup) Kützing, Dictyota dichotoma (Hudson) J.V.Lamouroux, Gracilaria bursa-pastoris (S.G.Gmelin) P.C.Silva, Ulva intestinalis Linnaeus species from Iskenderun Bay, Turkey against Escherichia coli, Bacillus cereus, Staphylococcus aureus, Pseudomonas aeruginosa,...

A model describing macroalgal early life stages and adult dynamics was used to quantify the effects of non-adult forms on the productivity of adult macroalgae in a eutrophic estuary. Predictions indicate that during years with mild winters and low rainfall, spring blooms will occur at the expense of the growth and reproduction of overwintering adults and without the contribution of the spore ba...

Green tides have occurred in the Yellow Sea, China, every year from 2007 to 2015. The free-floating Ulva prolifera (Müller) J. Agardh was the causative macroalgal species. The co-occurring, attached U. intestinalis was also observed. Photosynthetic capacities were determined using chlorophyll fluorescence in situ and after 7 days lab acclimation, and a significant differences were noted. Pigmen...

Seawater temperature varies across multiple spatial and temporal scales, yet the roles that such variation play in altering biotic interactions are poorly known. We assessed temperature-mediated feeding behavior exhibited by the herbivorous amphipod Ampithoe longimana collected from cold-temperate and subtropical estuaries (27 degrees N and 41 degrees N, respectively). Individuals were offered ...

The gross primary productivity of two seagrasses, Zostera marina and Ruppia maritima, and one green macroalga, Ulva intestinalis, was assessed in laboratory and field experiments to determine whether the photorespiratory pathway operates at a substantial level in these macrophytes and to what extent it is enhanced by naturally occurring shifts in dissolved inorganic carbon (DIC) and O2 in dense...
