“…Corallite length (L: maximum axis of the oral disk), width (W: minimum axis of the oral disk) and height (h: oral-aboral axis) were measured using calipers, and dry skeletal mass (M) was measured using a precision balance (Goffredo and Chadwick-Furman 2003). Corallite volume (V) was determined by applying the formula (Goffredo et al 2007)…”

Inferred calcification rate of a temperate azooxanthellate caryophylliid coral along a wide latitudinal gradient

Correlations between environmental parameters (depth temperature and solar radiation) and growth parameters (bulk skeletal density, linear extension rate and net calcification rate) of the solitary azooxanthellate coral, Caryophyllia inornata, were investigated along an 8°lati-tudinal gradient on the western Italian coasts. Net calcification rate correlated positively with both bulk skeletal density and linear extension rate, showing that C. inornata allocates calcification resources evenly to thickening the skeleton and increasing linear growth. Overall, the three growth parameters did not follow gradients in 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 azooxanthellate coral, Leptopsammia pruvoti, studied along the same latitudinal gradient. In a comparison of the response to temperature of all Mediterranean species whose growth has been investigated to date, azooxanthellate corals were more tolerant to temperature increases than zooxanthellate corals.

“…Corals were collected by SCUBA divers at the depth of 5-7 m depth on reefs facing south for B. europaea, and at 15-17 m under natural overhangs and caves for L. pruvoti. The sampling was performed at depths known to have high population densities and where previous studies on the reproductive biology, biometry, growth and population dynamics and genetics of the two species have been performed (Goffredo et al, 2002(Goffredo et al, , 2004a(Goffredo et al, ,b, 2006(Goffredo et al, , 2007(Goffredo et al, , 2008(Goffredo et al, , 2009a.…”

“…Leptopsammia pruvoti is an ahermatypic, azooxanthellate, solitary scleractinian coral, which is widely distributed in the Mediterranean basin and along the European Atlantic coast from Portugal to Southern England. It is one of the most common organisms under overhangs, in caverns, and crevices at 0-70 m depth, reaching up to thousands of individuals per square meter (Zibrowius, 1980;Goffredo et al, 2007). The yellow color and high density of polyps make this species attractive for recreational divers, who represent an important income for coastal tourist resorts in the Mediterranean (Mundet and Ribera, 2001).…”

In ecology, the standard tool for investigating the growth of marine species is the von Bertalanffy growth function (VBGF). The parameters of this function are usually estimated by methods that might induce bias in the results because the VBGF neither distinguishes between the variability at individual or population levels nor takes into account the contribution of site‐specific environmental factors. A major problem arises when environmental measures are not directly linked to data because they are observed at different spatial locations, scales, or times. In this case, the association between site‐specific environmental features and individual data might be forced. A Bayesian hierarchical nonlinear model (BHNLM) is proposed to provide reliable estimation of the VBGF parameters while taking into account biological information and site variability. We illustrate the advantages of the hierarchical structure that allow us to capture the differences among species and sites when environmental information is ignored. The proposal is assessed through a case study concerning two Mediterranean corals, Balanophyllia europaea and Leptopsammia pruvoti, improving both the statistical accuracy and the quantification of uncertainties affecting marine species growth.
