Coralline red algae from the Lower Pliocene Shagra Formation of Wadi Wizer, Red Sea coast, Egypt: Biofacies analysis, systematics and palaeoenvironmental implications
Coralline red algae are highly abunadant and well diversified in the well exposed carbonate deposits of the Lower Pliocene Shagra Formation at Wadi Wizer, Red Sea coast, Egypt. Lithostratigraphically, the Shagra Formation unconformably overlies the Late Miocene Marsa Alam Formation and underlies the Quaternary deposits. This carbonate facies is dominated by different assemblage of coralline red...
متن کاملCalcification of the Arctic coralline red algae Lithothamnion glaciale in response to elevated CO2
Rising atmospheric CO2 concentrations could cause a calcium carbonate subsaturation of Arctic surface waters in the next 20 yr, making these waters corrosive for calcareous organisms. It is presently unknown what effects this will have on Arctic calcifying organisms and the ecosystems of which they are integral components. So far, acidification effects on crustose coralline red algae (CCA) have...
متن کاملRed coralline algae assessed as marine pH proxies using 11B MAS NMR
Reconstructing pH from biogenic carbonates using boron isotopic compositions relies on the assumption that only borate, and no boric acid, is present. Red coralline algae are frequently used in palaeoenvironmental reconstruction due to their widespread distribution and regular banding frequency. Prior to undertaking pH reconstructions using red coralline algae we tested the boron composition of...
متن کاملStudies on Polyethers Produced by Red Algae
Two novel squalene-derived triterpenes, spirodehydrovenustatriol (3) and 14-keto-dehydrothyrsiferol (4) were isolated from the red alga Laurencia viridis, together with two new and unusual C(17) terpenoids, adejen A (5) and B (6). These truncated structures possess structural similarities with other known squalene metabolites and their biogenetic origin has been proposed on the basis of an oxid...
