Diel vertical migration
In this Quick Guide, Brierley provides a brief overview of a pervasive aspect of aquatic ecosystems, the daily movement of organisms up and down the water column.
متن کاملDiel vertical migration behaviour of Calanus hyperboreus
Samples historically collected and analysed by the Continuous Plankton Recorder survey in the North Atlantic and adjacent seas were used to examine temporal patterns in the near-surface abundance of copepodite stages V and V1 Calanus hyperboreus (n = a total of 32836 samples; mean latitude of samples = 54" N. SD = 6.7'). The occurrence of CV and V1 C. hyperboreus was largely restricted to sampl...
متن کاملDiel vertical migration of Arctic zooplankton during the polar night
High-latitude environments show extreme seasonal variation in physical and biological variables. The classic paradigm of Arctic marine ecosystems holds that most biological processes slow down or cease during the polar night. One key process that is generally assumed to cease during winter is diel vertical migration (DVM) of zooplankton. DVM constitutes the largest synchronized movement of biom...
متن کاملCircadian Clock Involvement in Zooplankton Diel Vertical Migration
Biological clocks are a ubiquitous ancient and adaptive mechanism enabling organisms to anticipate environmental cycles and to regulate behavioral and physiological processes accordingly [1]. Although terrestrial circadian clocks are well understood, knowledge of clocks in marine organisms is still very limited [2-5]. This is particularly true for abundant species displaying large-scale rhythms...
