“…When a sponge was found, a sample of its tissue was digested with sodium hypochlorite, and its spicular characteristics were examined under an optical microscope. The identification was done to the highest taxonomic level using the available literature (Carballo et al, 2004;Carballo and Cruz-Barraza, 2005;Bautista-Guerrero et al, 2006).

“…This work had four goals: (1) to study the species richness (S) and the frequency of invasion (IF) by boring sponges on living colonies of Pocillopora verrucosa (Ellis and Solander 1786) at Isla Isabel; (2) to quantify the carbonate dissolution rate of Cliona vermifera Hancock 1867 and Cliona flavifodina Rützler 1974, two of the most abundant and amply distributed boring sponges from the east Pacific Ocean (Carballo et al, 2004;Carballo et al, 2008). This is especially important to ensure the validity and generality of previous results for Pione cf.…”

SUMMARY Species richness (S) and frequency of invasion (IF) by boring sponges on living colonies of Pocillopora spp. from National Park Isla Isabel(México, East Pacific Ocean) are presented. Twelve species belonging to the genera Aka, Cliona, Pione, Thoosa and Spheciospongia were found, and 56% of coral colonies were invaded by boring sponges, with Cliona vermifera Hancock 1867 being the most abundant species (30%). Carbonate dissolution rate and sediment production were quantified for C. vermifera and Cliona flavifodinaRützler 1974. Both species exhibited similar rates of calcium carbonate(CaCO3) dissolution (1.2±0.4 and 0.5±0.2 kg CaCO3 m–2 year–1, respectively,mean ± s.e.m.), and sediment production (3.3±0.6 and 4.6±0.5 kg CaCO3 m–2year–1), resulting in mean bioerosion rates of 4.5±0.9 and 5.1±0.5 kg CaCO3 m–2year–1, respectively. These bioerosion rates are close to previous records of coral calcification per unit of area, suggesting that sponge bioerosion alone can promote disequilibrium in the reef accretion/destruction ratio in localities that are heavily invaded by boring sponges. The proportion of dissolved material by C. vermifera and C. flavifodina (27 and 10.2%, respectively) confirms that chemical bioerosion plays an important role in sponge bioerosion and in the CaCO3 cycle in coral reefs.

A total of 900 coral fragments collected across 2 fringing reefs located southwest of Mexico, La Entrega (LE) and San Agustín (SA), were examined for the presence of boring sponges. Of all samples, 43% were invaded by boring sponges, and 7 species belonging to 5 genera (Aka, Cliona, Pione, Cliothosa and Thoosa) were identified. The most abundant species were Cliona vermifera (17.9%), Cliona sp. (10.8%), A. cryptica (7.8%) and P. carpenteri (6.0%). The distribution and abundance of the species varied considerably throughout the reef area (margin and platform) and displayed certain selectivity for specific calcareous substrata. C. vermifera, Cliona sp., A. cryptica and P. carpenteri were most common on the reef margins, while T. calpulli was common on the central platform. A. cryptica, P. carpenteri, and Cliothosa hancocki were frequently found living in the immediate vicinity of live coral tissue, contrary to C. vermifera, T. calpulli and Cliona mucronata, which preferentially bored coral rubble. The results showed that reef margins had a significantly higher infestation level than the platforms (mean infestations of 60.6 and 26.2%, respectively). There were also differences between reefs. The infestation was higher on LE than on SA (48.6 and 38.2%, respectively), and these differences were larger between the platforms of the 2 reefs (41.3 and 11.1%, respectively). In general, the results of the present study have demonstrated that the diversity and abundance of species, as well as the infestation of coral frameworks by sponges, was significantly higher in the margin at both reefs studied and on the platform of LE, where the availability of exposed carbonate substrate was higher. In the margin of these reefs, the consequences of boring went far beyond the mere hollowing out of a few cavities, since by weakening the coral's attachment to the substrate, the sponges accelerated coral loss and restructured the reef edge. This pattern may have important implications for the preservation of the reef framework.

Amongst these, the boring sponges are considered one of the main agents that modify coral reef ecosystems (Goreau & Hartman 1963, MacGeachy 1977. Globally, they are the most common type of macroendolith and are responsible for more internal degradation of coral than any other group of organisms, internally (Perry 1998). They can accelerate the erosion of the reef framework (Tunnicliffe 1979) and cause a shift in the carbonate balance (Rose & Risk 1985).
