Photosymbiosis in planktonic foraminifera across the Palaeocene-Eocene Thermal Maximum ...
Under stress, corals and foraminifera may eject algal symbionts ('bleach'), which can increase mortality. How bleaching relates to species viability over warming events is of great interest given current global warming. We use size-specific isotope analyses and abundance counts to examine...
