Modern foraminifera

Modern seawater acidification: the response of foraminifera to high-CO2 conditions in the Mediterranean Sea

Actin Phylogeny of Foraminifera

Molecular phylogenies of foraminifera are commonly inferred from the small subunit rRNA (SSU) genes, which can easily be obtained from single cells isolated from environmental samples. The SSU phylogenies, however, are often biased by heterogeneity of substitution rates, and their resolution of higher level relationships is often very low. The sequences of protein-coding genes provide an import...

foraminifera and stable isotopes

Foraminiferal stable isotopes and assemblages from Franz Victoria and St. Anna troughs provide a valuable record of freshwater and Atlantic Water flows to the northern Barents and Kara seas from deglaciation to present. The dO and dC of planktonic Neogloboquadrina pachyderma (s) and benthic Elphidium excavatum were up to 1.4% lower than present at ca 13, 11.5, and 10 Cka (global sea-level corre...

Ba incorporation in benthic foraminifera

Barium (Ba) incorporated in the calcite of many foraminiferal species is proportional to the concentration of Ba in seawater. Since the open ocean concentration of Ba closely follows seawater alkalinity, foraminiferal Ba /Ca can be used to reconstruct the latter. Alternatively, Ba /Ca from foraminiferal shells can also be used to reconstruct salinity in coastal settings in which seawater Ba con...
