Phytoplankton Tune Local pH to Actively Modulate Circadian Gravitactic Behavior

open access: yesAdvanced Physics Research, EarlyView.
Diel vertical migration hides an unexpected twist: Phytoplankton quietly engineer their local pH landscape, splitting into behaviorally distinct sub‐groups which stay separated even in identical conditions. Circadian pH changes, occuring over the course of a day, reshape their gravitactic behavior and physiological functions in ways scientists have ...
