Response of large benthic foraminifera to climate and local changes: Implications for future carbonate production

چکیده
Large benthic foraminifera are major carbonate components in tropical platforms, important producers, stratigraphic tools and powerful bioindicators (proxies) of environmental change. The application large coral reef environments has gained considerable momentum recent years. These modern ecological assessments often carried out by micropalaeontologists or ecologists with expertise the identification foraminifera. However, have been under-represented favour macro reef-builders, for example, corals calcareous algae. contribute about 5% to reef-scale sediment production. Their substantial size abundance reflected their symbiotic association living algae inside tests. When foraminiferal holobiont (the combination between host microalgal photosymbiont) dies, remaining test renourishes supply, which maintains stabilizes shorelines low-lying islands. Geological records reveal episodes (i.e. late Palaeocene early Eocene epochs) prolific production warmer oceans than today, absence corals. This begs deeper consideration how will respond under future climatic scenarios higher atmospheric carbon dioxide (pCO2) oceans.

Calcium carbonate production response to future ocean warming and acidification
Anthropogenic carbon dioxide (CO2) emissions are acidifying the ocean, affecting calcification rates in pelagic organisms, and thereby modifying the oceanic carbon and alkalinity cycles. However, the responses of pelagic calcifying organisms to acidification vary widely between species, contributing uncertainty to predictions of atmospheric CO2 and the resulting climate change. At the same time...
متن کاملBenthic foraminifera in Hornsund, Svalbard: Implications for paleoenvironmental reconstructions
Modern hydrology of a typical Arctic fjord (Hornsund, SW Spitsbergen, Sval− bard) was investigated and compared with commonly used in paleoceanography proxies: benthic foraminiferal assemblages and their stable isotope ( 18O and 13C) composition. The benthic foraminifera from Hornsund comprised 45 species and 28 genera. Their spatial variations follow the zonation pattern, resulting from the in...
متن کاملOcean acidification induces biochemical and morphological changes in the calcification process of large benthic foraminifera.
Large benthic foraminifera are significant contributors to sediment formation on coral reefs, yet they are vulnerable to ocean acidification. Here, we assessed the biochemical and morphological impacts of acidification on the calcification of Amphistegina lessonii and Marginopora vertebralis exposed to different pH conditions. We measured growth rates (surface area and buoyant weight) and Ca-AT...
متن کاملVariation in sensitivity of large benthic Foraminifera to the combined effects of ocean warming and local impacts
Large benthic foraminifera (LBF) are crucial marine calcifiers in coral reefs, and sensitive to environmental changes. Yet, many species successfully colonise a wide range of habitats including highly fluctuating environments. We tested the combined effects of ocean warming, local impacts and different light levels on populations of the common LBF Amphistegina lobifera collected along a cross-s...
