Seaweed and seagrasses

In the early life stages of a coralline alga, mortality and growth abnormalities increased with small changes in pH. However, rate of growth remained similar, potentially by re-directing [...]

A coralline red alga that lives in tide pools, where it is common for CO2 levels to fluctuate tremendously daily and seasonally, was relatively robust to ocean acidification conditions, [...]

Ocean acidification may favor growth of algal turfs rather than kelp forests. Such a change would affect the many species associated with algal turf or kelp forest habitats.

When grown under ocean acidification conditions, a non-calcifying seaweed (Chondrus crispus) grew to cover more area, while a calcifying alga (Corallina officinalis) decreased in the area it [...]

A coralline alga took up and used carbon and nutrients differently when living under ocean acidification conditions for 12 weeks, and the changes affected its ability to compete with [...]

Growth and photosynthetic efficiency of a coralline alga decreased under high CO2 levels. These changes could affect the alga’s ability to compete with other macroalgae (seaweeds). [...]

The calcium carbonate skeleton of a coralline red alga was estimated to become highly vulnerable to dissolving at an aragonite saturation state between 1.1 and 0.9, which is projected to occur in [...]

The release of dimethylsulphoniopropionate (DMSP) by marine algae has major impacts on the global sulphur cycle and may influence local climate through the formation of dimethylsulphide (DMS). [...]

Increased CO2 and temperature acted together to increase the growth of algal turfs, which produced twice as much biomass and covered four times as much space. Experimental removal of algal turfs [...]

The effects of ocean acidification on the growth and shell production by juvenile and adult shelled molluscs are variable among species and even within the same species, precluding the drawing of [...]
