“…Anthropogenic nitrogen enrichment of waters was proved to enhance the settlement of boring spionid polychaetes on corals in the Red Sea, causing coral skeleton aberrations (Wielgus et al, 2006). Casoli et al (2019) proved that boring activities of polychaetes increased with the increase in the abundance of ascidians, barnacles and bryozoans on limestone panels in the Mediterranean Sea. In Ildırı Bay, where intense fish farming and tourism activities take place at some locations, anthropogenic disturbance affected the composition of the benthic fauna (Ergen In the western Mediterranean, some boring sponges (Cliona spp.)…”

“…In a previous experimental study performed on the Tyrrhenian coast of Italy by Casoli et al (2019), two polychaete species, namely Polydora ciliata and Dodecaceria concharum, were reported as borers on limestone panels. However, the occurrence of these two species in the Mediterranean is highly questionable (see Çinar et al, 2014) and previous records of P. ciliata in the Mediterranean and Black Sea were assigned to different species such as P. cornuta (Çinar et al, 2005).…”

“…The distribution of boring eunicid species on scales of the endemic phanerogame Posidonia oceanica (Linnaeus) Delile, 1813 has been relatively well-studied in the region (Gambi, 2002;Gambi et al, 2005). However, there is only one study that specifically focused on the distribution of boring species on limestone rocks in the Mediterranean Sea (Casoli et al, 2019).…”

The present study reports polychaetes that bore into limestone rocks along the east coast of the Aegean Sea (eastern Mediterranean). Rock materials were collected at two depth intervals (0–5 and 5–10 m) at 15 stations in four localities of Ildırı Bay. A total of 276 specimens belonging to 12 species and four families (Eunicidae, Spionidae, Cirratulidae and Sabellidae) were recorded. Specimens belonging to Dodecaceria and Pseudopotamilla were identified at the genus level, because they differ from described species, were few in number or were in poor condition. Dipolydora giardia is a new species to the marine fauna of Turkey. The most dominant and frequent family in the area was Eunicidae, followed by Spionidae. Lysidice ninetta and L. margaritacea comprised 59% of the total number of individuals. The number of species and individuals, and the diversity index did not change with regard to depth or locality. Two species assemblages were found in the area, mainly formed by Dipolydora and Lysidice species. The Lessepsian species, Palola valida, which is a new record for the Aegean Sea, occurred abundantly at the study sites, posing a risk of damage to limestone rocks in the Mediterranean Sea. The morphological features of the species identified at the generic level and the burrow structure of these species are presented. The burrow shapes of Palola siciliensis and P. valida were described for the first time in the present study; they constructed complicated galleries, including more than four entrances.

“…Internal bioerosion (sensu Neumann, 1966) is generally due to a suite of endolithic organisms, including both microborers (<100 µm large) and macroborers (>100 µm; Tribollet and Golubic, 2011). Usually, the bioerosion processes on new substrates show a temporal succession that begins with microborers, settling within 1 year (Tribollet and Golubic, 2005;Färber et al, 2015;Grange et al, 2015), and continue with macroborers, which become dominant after 2-3 years Casoli et al, 2016bCasoli et al, , 2019. Macroborers comprise various organisms from a wide range of taxonomic groups, including sponges (e.g., Rosell and Uriz, 2002;Calcinai et al, 2011), polychaetes (e.g., Hutchings, 2008;Casoli et al, 2019), sipunculids (e.g., Risk et al, 1995;Gherardi and Bosence, 2001), and bivalves (e.g., Schiaparelli et al, 2005;Casoli et al, 2016b).…”

“…Most of the few long-term experiments to simultaneously measure both bioconstruction and bioerosion processes have been conducted in tropical habitats (e.g., Silbiger et al, 2014Silbiger et al, , 2016. Although some medium-and long-term field experiments on bioerosion processes have been carried out also in the Mediterranean Sea Casoli et al, 2016bCasoli et al, , 2019Färber et al, 2016), these processes have never been investigated on coralligenous reefs of the northern Adriatic Sea, whose formation and maintenance of the diversity are poorly known. The purpose of this study is to shed light on the bioconstruction and bioerosion processes taking place in the main coralligenous reef typologies occurring in the northern Adriatic continental shelf.…”

Bioconstruction and Bioerosion in the Northern Adriatic Coralligenous Reefs Quantified by X-Ray Computed Tomography

The northern Adriatic continental shelf hosts several coralligenous reefs rising from the sedimentary bottom and characterized by three main benthic assemblages, respectively, dominated by algal turfs, encrusting calcareous rhodophyte (ECRs) or erect sponges. Bioconstruction and bioerosion processes have been investigated using recruitment travertine limestone tiles deployed in a random site for each main benthic assemblages off Chioggia, 6.1–14.4 km offshore and 20.2–25.4 m depth. Tiles were retrieved after 3 and 12 years and analyzed by X-ray computed tomography (CT), allowing for non-destructively identifying and quantifying deposited and eroded limestone. The main builders were ECRs, serpulids, bryozoans, barnacles, and the bivalves Anomia ephippium, while the most effective borers were sponges from the genus Cliona and the bivalve Rocellaria dubia. The deposition of limestone after 12 years was greater at the site MR08 dominated by ECRs (12.52 ± 2.22 kg m–2), intermediate at the site P213 dominated by erect sponges (4.20 ± 1.24 kg m–2), and lower in the site P204 dominated by algal turfs (2.20 ± 0.72 kg m–2). At MR08, the deposition rate did not vary much over time (from 1.295 ± 0.270 to 1.080 ± 0.198 kg m–2 a–1), while in the other two sites, it significantly slowed down after the first survey period: from 0.952 ± 0.199 to 0.350 ± 0.103 kg m–2 a–1 at P213, and from 1.470 ± 0.462 to 0.203 ± 0.058 kg m–2 a–1 at P204. The amount of eroded limestone increased with the exposure time, with no significant differences among sites, from 1.13 ± 0.29 to 10.39 ± 1.14 kg m–2 on average at 3 and 12 years, respectively. The bioerosion rate also increased with the exposure time and was slightly higher at MR08 (from 0.682 ± 0.208 to 1.105 ± 0.088 kg m–2 a–1), mostly eroded by Cliona rhodensis in addition to C. viridis, compared to P204 (from 0.267 ± 0.078 to 0.676 ± 0.172 kg m–2 a–1) and P213 (from 0.179 ± 0.065 to 0.816 ± 0.171 kg m–2 a–1). Overall, bioconstruction has overcome the bioerosion processes in 3 years. In 12 years, the estimated net balance was essentially nil at all sites. Combining field experiment and CT analysis, this study provides the first quantification of the bioerosion and bioconstruction processes in the northern Adriatic coralligenous reefs, a fundamental step toward their conservation.

Bioerosion features of boring polydorid polychaetes in the North Adriatic Sea

et al. 2022

Considering the pivotal role played by erosive organisms in the marine habitat and the scanty knowledge of this phenomenon in the Mediterranean Sea, the present study aimed to identify the pioneer excavating organisms occurring in the first stages of bioerosion, providing the first estimation of their rate of erosion along the North Adriatic Sea. Bioerosion activity was investigated by deploying sets of limestone panels for a period of 2 years. Moreover, micro-computed tomography was used for the first time to study polychaete erosion, confirming it is a very useful tool for the description of erosion processes. Blocks were placed in the touristic harbor Marina Dorica (Ancona) in July 2017 and periodically collected, the first time after a 6-month period, then bimonthly. Two species of the polychaete genus Polydora were the only boring organisms that settled on the experimental substrates. Erosion rate was estimated by measuring the holes produced by both worm species, and the eroded volumes obtained by resin casts of the holes. Polydora appeared after 6 months of exposure significantly changing its density rates (holes·100 cm−2·month−1) during the exposure, being comparable with densities reported from tropical areas. The erosion rate on the contrary is lower, reaching values of 0.053 g·cm−2·year−1.
