Emiliania huxleyi is a globally-distributed coccolithophore with a major influence on beogeochemical cycling via the production of large, ephemeral blooms. Because of its global distribution, Emiliania huxleyi has a wide thermal range and apparently a high capacity for short-term acclimation and long-term adaptation to thermal conditions. We are studying this capacity in the lab via both traditional experimental acclimation approaches in semi-continuous culture, and via tracking gene expression changes in response to thermal conditioning in the taxon via transcriptomics.
