A sparsely encrusted hardground with abundant Trypanites borings from the Llandovery of the Velise River, western Estonia (Baltica) [PDF]
Estonian Journal of Earth Sciences, 2016 The Päärdu hardground from the Telychian (Rumba Formation) of western Estonia is sparsely encrusted (0.4% of the studied surface) by possible tabulate corals, sheet-like bryozoans and discoidal echinoderm holdfasts.

Reef Bioerosion: Agents and Processes
, 2010 Coral reef maintenance depends on the balance between constructive and destructive forces. Constructive forces are mainly calcification and growth of corals and encrusting coralline algae. Destructive forces comprise physical, chemical, and biological erosion.

Boreas, Volume 55, Issue 2, Page 585-599, April 2026.Bioerosional scars made by limpets (Patella) on a cliff in Co. Antrim, Northern Ireland, indicate a Mid‐Holocene RSL of +7.8±0.55 m relative to local mid‐tide level today. This is higher than previous empirical data for the region and extrapolated levels from raised shorelines in Scotland but consistent with some recent GIA models.

Sedimentology, Volume 73, Issue 3, Page 593-619, April 2026.ABSTRACT Mesophotic reefs are located in low light conditions which, depending on the region, are usually found in water depths greater than ~30 m. They are less affected by ocean warming than reefs found in shallower water depths and thus might become increasingly important for the sustainability of marine biodiversity.

Seawater carbonate chemistry and bioerosion of croal reef
, 2017 Ocean acidification (OA), the gradual decline in ocean pH and [CO3 ] 2- caused by rising levels of atmospheric CO2, poses a significant threat to coral reef ecosystems, depressing rates of calcium carbonate (CaCO3) production, and enhancing rates of ...

Sedimentology, Volume 73, Issue 3, Page 706-741, April 2026.ABSTRACT Understanding the biotic and abiotic influences on the deposition and diagenesis of recent microbial carbonates is crucial for addressing the environmental and ecological significance of ancient organosedimentary structures. This study investigates these factors and their expression in the microstructure of Holocene tufa thrombolites from a ...

Half a century of echinoid population decline in the northern Gulf of Aqaba, Red Sea
Journal of Animal Ecology, Volume 95, Issue 3, Page 443-454, March 2026.Multi‐decadal monitoring in the Gulf of Aqaba, northern Red Sea, reveals severe (>90%) declines of key echinoid grazers. These declines signify a collapse of crucial herbivory functions underpinning coral reef resilience. Results implicate accelerating anthropogenic stress as a principal driver, emphasizing the urgent need for sustained, species ...

Micrographs showing the patterns of bioerosion and associated staining/inclusions observed.
, 2018 4A) Sample from TB18 with no bioerosion (M49); 4B) Sample from TB18 with arrested bioerosion (M37). The densest bioerosion is seen in an area close to the periosteal surface, here seen as white spots which are holes left after etching of the localized ...
