“…In summary, our accumulated experimental evidence this study) in concert with the results of Emson (1966), Duckworth and Peterson (2013), and Fang et al (2013) suggests that the observed OA effect on sponge bioerosion applies (1) across latitudes, considering the wide biogeographic distribution of the investigated species, (2) for sponges of the alpha (C. celata), beta (C. orientalis), and gamma (C. cf. celata) growth form (sensu Schönberg 2008), and (3) for different feeding strategies, i.e.…”

“…Reis and Leão (2000) reported a range of 0.1-3.0 and means of 0.96-1.00 kg removed substrate m -2 year -1 from different turbid reef sites at north Bahía, Brazil. In their pH experiments, Duckworth and Peterson (2013) found a somewhat lower total bioerosion rate of 0.26 ± 0.05 kg m -2 year -1 for ambient conditions for the local representative of C. cf. celata off the coast of New York State.…”

“…Even though this scenario bears a positive side effect by partially buffering OA (dissolving carbonate lowers seawater pCO 2 ; Andersson and Gledhill 2012), the expected consequences are clearly detrimental for wild and farmed shellfish populations (e.g. Warburton 1958b;Duckworth and Peterson 2013), as well as for calcareous framework builders in tropical and cold-water coral reef ecosystems Andersson and Gledhill 2012;Kennedy et al 2013;Fang et al 2013). …”

Sponge bioerosion accelerated by ocean acidification across species and latitudes?

In many marine biogeographic realms, bioeroding sponges dominate the internal bioerosion of calcareous substrates such as mollusc beds and coral reef framework. They biochemically dissolve part of the carbonate and liberate so-called sponge chips, a process that is expected to be facilitated and accelerated in a more acidic environment inherent to the present global change. The bioerosion capacity of the demosponge Cliona celata Grant, 1826 in subfossil oyster shells was assessed via alkalinity anomaly technique based on 4 days of experimental exposure to three different levels of carbon dioxide partial pressure (pCO 2 ) at ambient temperature in the coldtemperate waters of Helgoland Island, North Sea. The rate of chemical bioerosion at present-day pCO 2 was quantified with 0.08-0.1 kg m -2 year -1 . Chemical bioerosion was positively correlated with increasing pCO 2 , with rates more than doubling at carbon dioxide levels predicted for the end of the twenty-first century, clearly confirming that C. celata bioerosion can be expected to be enhanced with progressing ocean acidification (OA). Together with previously published experimental evidence, the present results suggest that OA accelerates sponge bioerosion (1) across latitudes and biogeographic areas, (2) independent of sponge growth form, and (3) for species with or without photosymbionts alike. A general increase in sponge bioerosion with advancing OA can be expected to have a significant impact on global carbonate (re)cycling and may result in widespread negative effects, e.g. on the stability of wild and farmed shellfish populations, as well as calcareous framework builders in tropical and cold-water coral reef ecosystems.

“…Schönberg (2008) provided a first glimpse of a pH gradient toward the etching sites using micro-sensors which may indicate that sponges do indeed alter the chemistry at the site of bioerosion. Although the underlying physiological and mechanical processes employed by the sponges to erode are currently unknown, a number of studies have shown that an increase in pCO 2 of the ambient water results in increased bioerosion rates (Wisshak et al, 2012(Wisshak et al, , 2013Duckworth and Peterson, 2013;Fang et al, 2013a), suggesting that changes in seawater chemistry directly affect the saturation state at the site where the coral aragonite is dissolved.…”

Combined Effects of Experimental Acidification and Eutrophication on Reef Sponge Bioerosion Rates

et al. 2017

Health of tropical coral reefs depends largely on the balance between constructive (calcification and cementation) and destructive forces (mechanical-chemical degradation). Gradual increase in dissolved CO 2 and the resulting decrease in carbonate ion concentration ("ocean acidification") in ocean surface water may tip the balance toward net mass loss for many reefs. Enhanced nutrients and organic loading in surface waters ("eutrophication"), may increase the susceptibility of coral reef and near shore environments to ocean acidification. The impacts of these processes on coral calcification have been repeatedly reported, however the synergetic effects on bioerosion rates by sponges are poorly studied. Erosion by excavating sponges is achieved by a combination of chemical dissolution and mechanical chip removal. In this study, Cliona caribbaea, a photosymbiont-bearing excavating sponge widely distributed in Caribbean reef habitats, was exposed to a range of CO 2 concentrations, as well as different eutrophication levels. Total bioerosion rates, estimated from changes in buoyant weights over 1 week, increased significantly with pCO 2 but not with eutrophication. Observed chemical bioerosion rates were positively affected by both pCO 2 and eutrophication but no interaction was revealed. Net photosynthetic activity was enhanced with rising pCO 2 but not with increasing eutrophication levels. These results indicate that an increase in organic matter and nutrient renders sponge bioerosion less dependent on autotrophic products. At low and ambient pCO 2 , day-time chemical rates were ∼50% higher than those observed at night-time. A switch was observed in bioerosion under higher pCO 2 levels, with night-time chemical bioerosion rates becoming comparable or even higher than day-time rates. We suggest that the difference in rates between day and night at low and ambient pCO 2 indicates that the benefit of acquired energy from photosynthetic activity surpasses the positive effect of increased pCO 2 levels at night due to holobiont respiration. This implies that excavation must cost cellular energy, by processes, such as ATP usage for active Ca 2+ and/or active proton pumping. Additionally, competition for dissolved inorganic carbon species may occur between bioerosion and photosynthetic activity by the symbionts. Either way, the observed changing role of symbionts in bioerosion can be attributed to enhanced photosynthetic activity at high pCO 2 levels.
