In the recent discussion how biotic systems may react to ocean acidification caused by rapid rise in carbon dioxide partial pressure (pCO2) marine realm, substantial research is devoted calcifiers such as stony corals. The antagonistic process – biologically induced carbonate dissolution via bioerosion has largely been neglected. Unlike skeletal growth, we expect chemical means be facilitated a high-CO2 world. This study focuses on one of most detrimental bioeroders, sponge Cliona...
Bioerosion of calcium carbonate is the natural counterpart biogenic calcification. Both are affected by ocean acidification (OA). We summarize definitions and concepts in bioerosion research knowledge context OA, providing case examples meta-analyses. Chemically mediated relies on energy demanding, biologically controlled undersaturation or acid regulation increases with simulated as does passive dissolution. Through substrate weakening both processes can indirectly enhance mechanical...
Dendritic and/or rosetted microborings in calcareous and osteic skeletal substrates have a diverse trace fossil record, spanning most of the Phanerozoic, whereas ichnodiversity comparable bioerosion traces produced modern seas is rather limited. The prominent occurrences are known from Devonian brachiopods Upper Cretaceous belemnite rostra. Ichnotaxonomically, they comprised within one few ichnofamilies established to date, Dendrinidae Bromley et al., 2007. As an outcome present revision...
The Cambrian explosion (CE) and the great Ordovician biodiversification event (GOBE) are two most important radiations in Paleozoic oceans. We quantify role of bioturbation bioerosion ecospace utilization ecosystem engineering using information from 1367 stratigraphic units. An increase all diversity metrics is demonstrated for Ediacaran-Cambrian transition, followed by a decrease values during middle to late Cambrian, more modest Ordovician. A marked ichnodiversity ichnodisparity shown CE...

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 carbonate liberate so-called sponge chips, a process that is expected to be facilitated accelerated in more acidic environment inherent present global change. The capacity demosponge Cliona celata Grant, 1826 subfossil oyster shells was assessed via alkalinity anomaly technique based on 4 days...
Abstract Knowledge of spatial biodiversity patterns is important for ecosystem assessment. Rhodoliths, free-living calcareous algae, are biotic components that structure the sea floor through their complex skeletons and tendency to accumulate in an area form rhodolith beds. Thereby, rhodoliths considered act as engineers promoting local biodiversity. In this study, beds Mosselbukta, Svalbard, was investigated analyse proposed link between presence by evaluating beam trawl underwater video...
In the temperate Azores carbonate factory, a substantial fraction of calcareous skeletal components is recycled by remarkable biodiversity biota producing bioerosion traces (incipient trace fossils). To study this biodiversity, experimental substrates were exposed to colonisation epilithic and endolithic organisms along bathymetrical gradient from 0 500 m depth, during 1 2 years exposure. The overall ichnodiversity very high comprises 56 ichnotaxa ichnoforms attributed cyanobacteria,...

By establishing the bioerosion ichnogenus Oichnus , Richard Bromley (1981) addressed 'small round holes in shells' and catalysed a series of still ongoing discussions on ichnotaxonomical principles.

ABSTRACT The calcareous matrix of rhodoliths can be composed one or more crustose coralline algae (CCA) taxa as well a mixed assemblage various encrusting organisms. Studies on modern and fossil assume such associations to vary with water depth. Our study explores the quantitative biological composition rhodolith matrices along bathymetric gradient at Arctic Svalbard archipelago. Using methodological combination virtual micro‐CT cross‐sections modified point counting approach, we found five...
Abstract. The rugged submarine topography of the Azores supports a diverse heterozoan association resulting in intense biotically-controlled carbonate-production and accumulation. In order to characterise this cold-water (C) factory 2-year experiment was carried out southern Faial Channel study biodiversity hardground communities for budgeting carbonate production degradation along bathymetrical transect from intertidal bathyal 500 m depth. Seasonal temperatures peak September (above...
Abstract There is an increasing number of studies reporting microplastic (MP) contamination in the Arctic environment. We analysed MP abundance samples from a marine ecosystem that has not been investigated this context and features high biodiversity: hollow rhodoliths gouged by bivalve Hiatella arctica . This filter feeder potentially accumulates MPs may therefore reflect rhodolith at northern Svalbard. Our analyses revealed 100% examined specimens were contaminated with MP, ranging between...
