Mediterranean rhodolith beds are priority marine benthic habitats for the European Community, because of their relevance as biodiversity hotspots and role in carbonate budget. Presently, typically occur within range 30–75 m water depth, generally located around islands capes, on flat or gently sloping areas. In framework a collaboration between University Milano-Bicocca Marine Protected Area “C...

Coralline algae that form rhodoliths are widespread globally and their skeletal growth patterns have been used as (paleo-) environmental proxies in a variety of studies. However, interruptions (hiati) within calcareous skeletons regarded problematic this context. Here we investigated how hiati the Arctic from Svalbard archipelago correspond to environment morphology. Using X-ray micro-computed ...

The fossil coralline fl ora of the Badenian bioclastic limestone outcropping in Northern Croatia is known by the name “Litavac”, shortened from “Lithothamnium Limestone”. The name was given to indicate that unidentifi ed coralline algae are the major component. In this fi rst contribution to the knowledge of the coralline fl ora of the Litavac, Lithothamnion valens seems to be the most common s...

Serravallian (middle Miocene) coralline algal assemblages at the southern margin of Guadalquivir Basin (southern Spain) occur as rhodoliths preserved in situ or very close to their growth habitats (autochthonous–parautochthonous assemblages) and also reworked remains (allochthonous assemblages). The former consist spherical built up by encrusting warty plants large fragments branches, whereas l...

During the Paleocene/Eocene Thermal Maximum, ~55.6 Ma, Earth experienced warmest event of last 66 Ma due to a massive release CO 2 . This lasted for ~100 thousands years with consequent ocean acidification (estimated pH = 7.8-7.6). In this paper, we analyze effects global environmental shift on coralline algal assemblages in Campo and Serraduy sections, south-central Pyrenees (Huesca, N Spain),...
