“…allocates enhanced calcification into linear extension (Lough and Barnes 2000), Orbicella annularis allocates calcification resources into denser skeletons (Carricart-Ganivet 2004). In the Mediterranean Sea, the zooxanthellate colonial coral C. caespitosa shows a similar strategy to massive Porites (Kružić et al 2012). …”

“…Net calcification of the endemic B. europaea and C. caespitosa is temperature dependent, while in the azooxanthellate L. pruvoti and C. inornata net calcification is unaffected by temperature. In particular, while net calcification rate of C. caespitosa is positively correlated with SST (Kružić et al 2012), net calcification of B. europaea has the opposite trend (Goffredo et al 2009). …”

“…living in the Hawaiian archipelago, in Thailand and on the Great Barrier Reef, net calcification rate increases with SST (Lough and Barnes 2000). In the Mediterranean Sea, the colonial zooxanthellate coral Cladocora caespitosa increases its net calcification rate with SST along a natural temperature gradient (Kružić et al 2012), but laboratory observations showed that long-term exposure to high temperature led to a decrease in net calcification (Rodolfo-Metalpa et al 2006). The net calcification rate of another zooxanthellate but solitary Mediterranean coral, Balanophyllia europaea, correlated negatively with increasing SST along a natural temperature gradient on the western Italian coast (Goffredo et al 2009), while the net calcification rate of the solitary azooxanthellate coral Leptopsammia pruvoti did not vary along the same gradient (Caroselli et al 2012).…”

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

et al. 2016

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.

“…For over a decade, mass mortality events have recurrently impacted Mediterranean benthic communities owing to prolonged heat waves that affect some emblematic sessile invertebrates (Cerrano et al 2000;Perez et al 2000;Garrabou et al 2009;Lejeusne et al 2009). The scleractinian coral Cladocora caespitosa (Linnaeus, 1767) is among these affected species and mortalities of its reefs have been recorded, including those in the Adriatic Sea (Kružić et al 2012), Gulf of La Spezia (Rodolfo-Metalpa et al 2005), and Columbretes Islands where over 50 % of the coral cover has been affected by necrosis during the last decade (Kersting et al 2013a). …”

Regional genetic differentiation among populations of Cladocora caespitosa in the Western Mediterranean

et al. 2014

Cladocora caespitosa is the only reef-forming zooxanthellate scleractinian in the Mediterranean Sea. This endemic coral has suffered severe mortality events at different Mediterranean sites owing to anomalous summer heat waves related to global climate change. In this study, we assessed genetic structure and gene flow among four populations of this species in the Western Mediterranean Sea: Cape Palos (SE Spain), Cala Galdana (Balearic Islands), Columbretes Islands, and L'Ametlla (NE Spain). The results obtained from Bayesian approaches, F ST statistics, and Bayesian analysis of migration rates suggest certain levels of genetic differentiation driven by high levels of selfrecruitment, a fact that is supported by egg-retention mechanisms. Conversely, genetic connectivity among distant populations, even if generally low, seems to be related to sporadic dispersal events through regional surface currents linked to the spawning period that occurs at the end of summer-beginning of autumn. These features, together with a certain isolation of the Columbretes Islands, could explain the regional genetic differentiation found among populations. These results help to better understand population structure and connectivity of the species and will serve as an approach for further studies on different aspects of the biology and ecology of C. caespitosa.

“…In addition to warming events, competition with invasive algae likely contributed to the mortality of this coral species (Kersting et al, 2015). Invasive algae were observed in different regions of Mediterranean Sea where living C. caespitosa are present (Kersting et al, 2014a; Kružić et al, 2012). The long life and the low natural mortality of this coral species buffer the low recruitment rates.…”

During an expedition in 2014 in the Gulf of Gabes that aimed to evaluate the impact of the pollution of the phosphate industry on the marine environment, numerous dead coral fragments were retrieved from several stations along a 18 km long transect in front of the industry complex of Gabes. Detailed taxonomy of these coral fragments shows clearly that all fragments belong to the species Cladocora caespitosa (Linnaeus, 1758). Quantitative analysis of the coral fragments indicates a positive correlation with stations characterized by positive bathymetric anomalies. We suggest the presence of probable small-scaled (up to 4 m high) biogenic (palaeo-) build-ups composed mainly of coral colonies and bryozoans. Radiocarbon dating of three coral fragments show ages as old as 1897, 1985 and 1986 AD and suggests the presence of living C. caespitosa as close as 6 km to the phosphate treatment industry of Gabes at least until 1986 AD. This latter age coincides with the construction of the ammonium phosphate production plant, in 1979, in the Gulf of Gabes with an increase of the natural phosphate production. The higher impact of pollution on the marine environment in the inner part of the Gulf of Gabes likely induced the decline of C. caespitosa. This is well in agreement with enhanced siltation processes suggested by the sedimentary facies and grain-size analyses presently characterizing the Gulf of Gabes nowadays.
