Hardgrounds represent synsedimentary cemented stratigraphic beds that form at or near the seafloor. Borings a key line of evidence for investigations hardground development and record evolution bioerosion boring organisms. The unequivocal identification borings is done through crosscutting relationship between proposed hard substrate, such as lithoclasts and/or shells, with morphological criter...

Bioerosion increases the topographic complexity of soft rock habitats, thereby increasing species diversity. This increase in species diversity may either be associated with an increase in complexity or may simply be a consequence of the increase in available surface area for colonisation. The influence of habitat modification by piddocks on intertidal species richness was investigated through ...

Crustose coralline algae (CCA) are major benthic calcifiers that play crucial roles in marine ecosystems, particularly coral reefs. Over the past two decades, epizootics have been reported for several CCA species on coral reefs worldwide. However, their causes remain often unknown in part because few studies have investigated CCA pathologies at a microscopic scale. We studied the cellular chang...

Ocean acidification (OA) impacts the physiology of diverse marine taxa; among them corals that create complex reef framework structures. Biological processes operating on coral reef frameworks remain largely unknown from naturally high-carbon-dioxide (CO2) ecosystems. For the first time, we independently quantified the response of multiple functional groups instrumental in the construction and ...

The deposits of the Carnian Kasımlar Formation within the Taurus Platform Units of south-western Turkey represent an important archive of a Late Triassic ecosystem. New palaeontological information was obtained by analysing the Kasimlarceltites mass occurrence, located within the Kasımlar Formation and named after the Lower Carnian (Julian) ammonoid genus Kasimlarceltites. This is the dominant ...
