Resumo(s)
Correlations between environmental parameters (sea surface temperature and solar radiation) and growth parameters (bulk skeletal density, linear extension rate and net calcification rate) of the solitary non-zooxanthellate Caryophyllia inornata, were investigated along an 8° latitudinal gradient on the western Italian coasts. Net calcification rate correlated positively both with bulk skeletal density and linear extension rate, showing that C. inornata allocates calcification resources evenly in thickening the skeleton and increasing linear growth. None of the three growth parameters correlated with any of the two environmental parameters, showing a different trend compared to most studies on zooxanthellate corals. However, the results are in agreement with the only previous analysis of an asymbiotic coral, Leptopsammia pruvoti studied along the same latitudinal gradient. These results support the idea that non-zooxanthellate corals could be more tolerant to temperature increases than symbiotic corals, at least for the few species whose all three growth components have been investigated so far, which are both from the Mediterranean Sea
