Vertical migration is a geographically and taxonomically widespread behaviour among
zooplankton that spans across diel and seasonal timescales. The shorter‐term diel vertical …

The regular movements of waves and tides are obvious representations of the oceans'
rhythmicity. But the rhythms of marine life span across ecological niches and timescales …

Endogenous programs that regulate annual cycles have been shown for many taxa,
including protists, arthropods, fish, mammals and birds. In migration biology, these programs …

Sunlight is the dominant control on phytoplankton biosynthetic activity, and darkness
deprives them of their primary external energy source. Changes in the biochemical …

Abstract The Nereid Platynereis dumerilii (Audouin and Milne Edwards (Annales des
Sciences Naturelles 1: 195–269, 1833) is a marine annelid that belongs to the Nereididae, a …

Understanding the vertical migration behaviour of Antarctic krill is important for
understanding spatial distribution, ecophysiology, trophic interactions and carbon fluxes of …

Background Circadian clocks allow organisms to anticipate daily fluctuations in their
environment by driving rhythms in physiology and behavior. Inter-organismal differences in …

Periodic light–dark cycles govern the timing of basic biological processes in organisms
inhabiting land as well as the sea, where life evolved. Although prominent marine …

In the pelagic environment diel vertical movements (DVM) are widespread across taxa, from
zooplankton ascending from day-time depths into surface layers at night to avoid visual …

Antarctic krill (Euphausia superba, hereafter krill) is a pelagic living crustacean and a key
species in the Southern Ocean ecosystem. Krill builds up a huge biomass and its …
