🌊 How might #OceanAcidification affect #Seaweeds? It may depend on whether they have a carbon dioxide (CO₂) concentrating mechanism (#CCM). A new #OA study in Botanica Marina compared four #RedAlgal anspecies & their photosynthetic responses to dissolved inorganic carbon.

🌱 Fine, filamentous #Seaweeds generally contained more Si than thicker forms, suggesting a possible structural role. Seaweeds also took up dissolved Si, with higher environmental Si increasing uptake and accumulation.

Wonder if these #brownalgae at Mill Bay #Salcombe #Devon are Dulse (Palmaria palmata) & Pepper Dulse (Osmundea pinnatifida), with the #redalgae Worm Weed (Dumontia contorta).
Also the marine #lichen (Lichina pygmaea). #algae #lichens #seaweed #phycologyfriday #seaweeds #alga #marinelife #sealife
