Dear Fellow Coral Reef Researchers,

Just drawing attention to this excellent new manuscript by Radecker et al.
which highlights well that, "CO2 limitation of Symbiodinium is a common
feature of stable cnidarian holobionts".


Results such as these provide strong support for the role of light- adn
temperature driven CO2-limitation as the primary driver of mass coral
bleaching events:


And explains why strongly autotrophic symbiotic corals are "the living
dead" in the Anthropocene ocean:


The results also infer the crucial importance of getting the
experimental/laboratory light requirements correct for testing bleaching
mechanism, and making inference from the lab to ecosystem scale. I will
write further on this in a separate listing.
