The most important groups of modern red calcareous algae are the Mg-calcite secreting Corallinales and Sporolithales, aragonitic Peyssonneliales Nemaliales. They common on world's shelves vulnerable to global warming lowering pH sea water, caused by ongoing increase in anthropogenic CO2. Among them, coralline ecosystem engineers major producers carbonate sediment, particular importance temperate cold seas. Corallines respond marine acidification rising temperature showing decreased net...
Abstract The protocols available for sampling and monitoring shallow subtidal rhodolith beds (RBs) are inadequate the deep Mediterranean analogues, need calibration in order to attain comparable results. After reviewing present knowledge of specificities RBs, framework ongoing international effort their conservation, a two‐step approach is suggested definition, identification, delimitation, description, monitoring. Regional mapping should be improved, RBs identified delimited as those areas...
Abstract Shallow-water Sporolithon rhodoliths from New Zealand are described here on the basis of shape, size, composition, internal structure, and major taphonomic attributes, with aim discussing their significance in framework current ecological paleoecological models rhodolith formation accumulation. The very shallow water environment (<2 m) Whangaparaoa Peninsula undergoes daily tidal currents seasonal storm conditions. These factors, along availability cobbles pebbles as suitable...
Despite their strong Raman scattering and importance in several applications the geological biological sciences, Mg‐calcites have not been thoroughly investigated by spectroscopy. In this study, we whether spectra of carbonates are sensitive to structural chemical changes occurring when Mg 2+ substitutes Ca calcite lattice. Different carbonate samples with variable content (from 0 20 mol% MgCO 3 ) inorganic origin first beamed under a spectrometer then analysed scanning electron...
The sequence stratigraphic framework and a summary of the fossil fauna upper Miocene portion Pisco Formation exposed along western side Ica River (southern Peru) is presented through new geological map encompassing an area about 200 km 2 detailed chronostratigraphic analyses. Extensive field mapping sedimentological study outcrop sections have shown that cyclical sediment unit composed at least three fining-upward, unconformity-bounded depositional sequences, designated P0, P1, P2 from...
Lithophyllum species in the Mediterranean Sea function as algal bioconstructors, contributing to formation of biogenic habitats such coralligenous concretions. In habitats, thalli , consisting crusts or lamellae with entire lobed margins, have been variously referred either one species, L. stictiforme two and cabiochiae recent literature. We investigated diversity phylogenetic relationships these algae by sequencing three markers ( psb A rbc L genes, cox 2,3 spacer), conjunction methods for...
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 “Capo Carbonara” (Sardinia, Italy), video explorations sampling collections three selected sites...
Along the Mediterranean Sea shelf, algal reefs made of crustose coralline algae and Peyssonneliales are known as Coralligenous. It ranks among most important ecosystems in because its extent, complexity, heterogeneity, supporting very high levels biodiversity. Descriptive approaches for monitoring purposes often aimed at assessing surficial ephemeral canopy, which is sustained controlled by occurrence long-lasting rigid structure base. This practice led to non-univocal definition...
Abstract. The coralligenous build-ups located on the Mediterranean shelf in front of Marzamemi (SE Sicily, Italy) represent useful natural examples to use studying relationship between skeletal organisms and non-skeletal components marine bioconstructions. Coralligenous are formed open systems, their comparison with coeval bioconstructions (biostalactites) confined environments, like submarine caves, allows depicting complex interactions metazoans microbial communities formations recent...
This study deals with the design and characterisation of glass-based materials for hermetic sealing ceramic components (α-to β''-Al2O3) in solid-electrolyte cells operating at approximately 300 °C. A silica-based commercially available glass a newly developed silica-free glass, potentially resistant to corrosion by molten sodium salts, are reviewed discussed. 25 wt% alumina powder is incorporated into both formulations. The sintering behaviour systems their wetting characteristics on...
Abstract Rhodoliths are nodular structures composed mainly of the superimposed thalli calcareous red algae. Because their development is controlled by an array ecological parameters, rhodoliths a valuable source palaeoenvironmental information. However, despite common use in palaeoecological reconstructions, stratigraphic significance rhodolith accumulations seldom has been addressed detail. In study Cenozoic rhodolith‐bearing deposits from North Island New Zealand, rhodolithic units,...
On the continental shelf off Cilento peninsula (eastern Tyrrhenian Sea) occurrence of more than 13 km2 maerl beds was documented through acoustic surveys. Swath bathymetric data along with a dense grid chirp-sonar profiles were acquired over 180 km2. The facies characterized on basis components analysis 32 grab samples collected at selected sites. Mapped maerl-beds are predominant submerged terraces located variable water depth (wd) between 42 and 52 m. This preferred distribution is...
Based on literature, the genus Lithophyllum was represented in whole Indian Ocean by 14 taxa, mostly need of revision a modern context. Molecular analyses integrated with morpho-anatomical comparisons between recently revised type material kotschyanum Unger, and related infraspecific lead to resumption L. affine, kaiseri, subreduncum, description socotraense sp. nov., yemenense subplicatum comb. et stat. nov. Detailed accounts are provided for each species, including keys, along information...
The succession of the Maiella massif is analyzed, focusing on colonial-coral bearing deposits occurring just below and immediately above Cretaceous/Paleogene boundary. Upper Cretaceous material dominated by rudists larger benthic foraminifera with a significant contribution from colonial corals. In Lower Paleocene, first two groups are absent corals dominate skeletal assemblage. This supports hypothesis good recovery carbonate production following end extinction their overall resilience....
