Article Synopsis
- Coral reefs are increasingly impacted by higher levels of dissolved inorganic and organic carbon due to ocean acidification and coastal eutrophication, particularly in stressed near-shore environments.
- An experimental study tested how elevated DIC and DOC influenced the growth of two calcifying green algae, showing that while both DIC and DOC reduced photosynthesis and calcification rates, the effects varied between species, with Halimeda incrassata being more negatively affected than Udotea flabellum.
- The findings suggest unexpected interactions between DIC and DOC—sometimes they can lessen each other's impacts—highlighting the need for species-specific understanding of how these factors alter reef ecology under future conditions.
Coral reefs are facing major global and local threats due to climate change-induced increases in dissolved inorganic carbon (DIC) and because of land-derived increases in organic and inorganic nutrients. Recent research revealed that high availability of labile dissolved organic carbon (DOC) negatively affects scleractinian corals. Studies on the interplay of these factors, however, are lacking, but urgently needed to understand coral reef functioning under present and near future conditions.

For calcifying green algae of the genus Halimeda, a key tropical carbonate producer that often occurs in coral reefs, no studies on these interactions have been reported. These data are however urgently needed to understand future carbonate production.
