We cultured<jats:italic>Planoglabratella opercularis</jats:italic>(d'Orbigny) and<jats:italic>Quinqueloculina yabei</jats:italic>Asano under controlled temperature (10°–25°C) and salinity (30–38) conditions. Both species show a linear correlation between Mg/Ca and temperature, but they differ in temperature sensitivity. Salinity does not significantly influence Mg/Ca. In the samples collected in nature, Mg/Ca and seawater temperatures are positively correlated, but there are more complexities than in the records for cultured specimens due to such factors as seasonal fluctuations in temperature. We conclude that Mg/Ca ratios in monospecific benthic foraminiferal samples may be used as a reliable temperature proxy, if the lifetime of the species is taken into account.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381699996378771330","@type":"Researcher","foaf:name":[{"@value":"Takashi
