3d Visualization of Bioerosion in Archaeological Bone

Journal of Archaeological Science, 2022
Palaeoradiology is increasingly being used in archaeological and forensic sciences as a minimally invasive alternative to traditional histological methods for investigating bone microanatomy and its destruction by diagenetic processes. To better understand ancient mortuary practices, taphonomic studies using microCT scanning methods are gaining an ever

Seawater carbonate chemistry and the bioerosion rates of two reef-dwelling Caribbean sponges

, 2022
Ocean acidification (OA) is expected to modify the structure and function of coral reef ecosystems by reducing calcification, increasing bioerosion, and altering the physiology of many marine organisms. Much of our understanding of these relationships is

Bioerosion in a changing world: a conceptual framework [PDF]

Ecology Letters, 2018
AbstractBioerosion, the breakdown of hard substrata by organisms, is a fundamental and widespread ecological process that can alter habitat structure, biodiversity and biogeochemical cycling. Bioerosion occurs in all biomes of the world from the ocean floor to arid deserts, and involves a wide diversity of taxa and mechanisms with varying ecological ...

Photosynthetically stimulated bioerosion in symbiotic sponges: the role of glycerol and oxygen [PDF]

, 2021
On coral reefs, some of the most aggressive calcium carbonate eroders are dinoflagellate-hosting sponges of the genus Cliona. Like in other marine taxa, the influence of these symbiotic microorganisms on the metabolism of the host sponge, and thereby on ...

Syn-vivo bioerosion of Nautilus by endo- and epilithic foraminiferans (New Caledonia and Vanuatu).

PLoS ONE, 2015
A variety of syn-vivo bioerosion traces produced by foraminiferans is recorded in shells of Nautilus sampled near New Caledonia and Vanuatu. These are two types of attachment scars of epilithic foraminiferans and two forms of previously undescribed ...

Ichnodiversity and bathymetric range of microbioerosion traces in polar barnacles of Svalbard

Polar Research, 2020
This first comprehensive investigation of microbioerosion traces in polar barnacles addresses two bathymetrical transects from the intertidal down to subtidal water depths in two different carbonate factories in the Svalbard Archipelago: the bay ...

Domichnial Borings in Serpulid Tube Walls: Prosperous Benthic Assemblages in the Cretaceous of France and the Czech Republic

Frontiers in Ecology and Evolution, 2022
The calcareous tubes inhabited by some polychaetes (some Serpulidae and the sabellid Glomerula) which are adapted to live sticking in soft ground, starting from the Permian, represent widespread but widely neglected and understudied substrates for ...

Ichnology of the Rhätsandstein in the Exter Formation (Triassic), Germany

Geological Journal, EarlyView.
Trace fossils from the Rhätsandstein of southern Germany record repeated colonization of high‐energy shallow‐marine substrates before the Triassic–Jurassic transition. The assemblage reflects environmental and preservational controls on ichnodiversity.

The ecology of the grazing urchin Echinometra mathaei at Ningaloo Marine Park [PDF]

, 2012
Sea urchins can have a significant influence upon the ecological structure of coral reefs through both bioerosion of substrata and by affecting competition for space.
