Dear All,

we would like to share a recent study on the effect of seawater warming and
acidification on coral mortality and growth, published in Scientific

This field study shows the combined warming and acidification effects on
mortality and growth of Mediterranean coral species transplanted, in
different seasons, along a natural pH gradient generated by CO2 vents. We
found a synergistic adverse effect on mortality rates for solitary and
colonial, symbiotic and asymbiotic corals. The net calcification rate of
the symbiotic species was not affected by decreasing pH, regardless of
temperature, while in the two asymbiotic species it was negatively affected
by increasing acidification and temperature, suggesting that symbiotic
corals may be more tolerant to increasing warming and acidifying conditions
compared to asymbiotic ones.
