Marine macroalgae are ecologically and economically important primary producers, being adjacent to human living areas and playing key roles in coastal carbon cycles. They are subject to both regional and global environmental changes in coastal waters, where environmental factors fluctuate dramatically due to high biological production and land runo...

Intertidal seaweeds are periodically exposed during low tide and thus experience extreme levels of desiccation. The physiological activity of seaweeds changes during this water loss process. This study examined how desiccation affects the photosynthesis and respiration of seaweeds from different intertidal levels, and whether the ability to retain...

In order to assess the ecological impacts of the atmospheric CO2 increase on the intertidal macroalgae during emersion, the photosynthesis of Enteromorpha linza (a green alga), Ishige okamurae (a brown alga) and Gloiopeltis furcata (a red alga) was investigated in air as a function of CO2 concentrations and water loss. Their photosynthesis was not...
