It is unclear which other species, such as coralline algae that facilitate the survival of vulnerable coral larvae, are also expanding into new areas u- or how successful young corals can be without them.
One organism that has been identified as most vulnerable to OA is a group of calcifying algae called coralline algae. (6) Coralline algae belong to an evolutionary old group of algae, the red algae or Rhodophyta ([phrase omitted], 'rose,' and [phrase omitted], 'plant').
2008) that vary with respect to exposure and contain hard substrate (bedrock and boulders/cobble) with ample quantities of benthic diatoms, and micro and macro-algae, and are often associated with crustose coralline algae that is thought to serve as a settlement cue (Roberts 2003).
This unique pink formation, crustose coralline algae, helps cement coral reefs together and is hard enough to walk on (though visitors should avoid stepping on the fragile coral itself).
The experiment revealed acute exposure led to net dissolution, meaning calcified organisms such as the coralline algae and starfish were dissolving.
It's known as crustose coralline algae, or CCA, and it's particularly sensitive to acidification, which is a major consequence of increased carbon dioxide in the Earth's atmosphere: the acidity of marine waters increases as our oceans absorb more and more carbon dioxide from the atmosphere.
'Seawater is already 30 per cent more acidic than it used to be and sensitive organisms such as crustose coralline algae are likely to be responding to those changes,' Fabricius says.
Macro- and calcareous algae abundance did not differ between reefs but high coralline algae abundance was measured in Shimoni compared to all other reefs.
"Research shows the pink encrusting algae, known as crustose coralline algae, may decrease in extent in a more acidic future ocean, as it incorporates calcium into its structure, and this becomes harder for organisms to obtain as the acidity of the seawater increases," said Stark.
