Phenotypic plasticity of coralline algae in a High CO2 world
It is important to understand how marine calcifying organisms may acclimatize to ocean acidification to assess their survival over the coming century. We cultured the cold water coralline algae, Lithothamnion glaciale, under elevated pCO2 (408, 566, 770, and 1024 μatm) for 10 months. The results show that the cell (inter and intra) wall thickness is maintained, but there is a reduction in growt...
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 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 کاملConvergence of joint mechanics in independently evolving, articulated coralline algae.
Flexible joints are a key innovation in the evolution of upright coralline algae. These structures have evolved in parallel at least three separate times, allowing the otherwise rigid, calcified thalli of upright corallines to achieve flexibility when subjected to hydrodynamic stress. As all bending occurs at the joints, stress is amplified, which necessitates that joints be made of material th...
متن کاملGrowth and high-resolution paleoenvironmental signals rhodoliths (coralline red algae): A new biogenic archive
We investigated rhodoliths (coralline red algae) from a subtropical ocality in the Gulf of California (Lithotharnniurn crassiusculurn) and a subarctic locality in Newfoundland (Lithotharnniurn glaciale) for their potential as paleoenvironmental rchives using microanalytical geochemical techniques tomeasure variations in ;5•80, Mg, and Ca. Rhodoliths are potentially well suited as recorders of s...
