Bivalve mollusk body clock genes may follow tidal rhythms

Circadian Biology Weekly Brief ↗PubMed ↗DOI ↗

Updated

Abstract

Oysters exhibit a strong tidal rhythm in their valve behavior alongside a daily rhythm.

  • Oysters display tidal rhythmicity in circadian clock genes and related genes.
  • A free-running experiment indicates the presence of an endogenous circatidal rhythm.
  • In field observations, oysters' valve behavior shows both circatidal and circadian patterns.
  • Half of the behavioral rhythms observed in the free-running experiment are circadian in nature.
  • The findings suggest that a single circadian/circatidal clock may regulate bivalve behavior at both tidal and daily frequencies.
