| Summary: | Genetic clocks are a ubiquitous ancient and adaptive mechanism enabling organisms to anticipate environmental rhythms and to regulate behavioral, physiological and behavioral processes accordingly. Whilst terrestrial circadian clocks are well studied and understood, knowledge about the clock systems in marine organisms is still limited. This is particularly true for abundant species displaying large-scale rhythms like diel vertical migration (DVM) that contribute significantly to shaping their respective ecosystems. Here, we describe endogenous and highly rhythmic patterns in the biology of the ecologically important and highly abundant planktic copepod Calanus finmarchicus. This species shows circadian rhythms of DVM, metabolism, and most core circadian clock genes (clock, period1, period2, timeless, cryptochrome2, clockwork orange) in the laboratory. In the field, copepods from shallow water (0-50m) have more robust rhythmic clock gene oscillations than those caught in deeper water (140-50m). Further, peak ... : Supplement to: Häfker, N Sören; Meyer, Bettina; Last, Kim; Pond, David W; Hüppe, Lukas; Teschke, Mathias (2017): Circadian clock involvement in zooplankton diel vertical migration.
