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 کاملEnhancement of anammox by the excretion of diel vertical migrators.
Measurements show that anaerobic ammonium oxidation with nitrite (anammox) is a major pathway of fixed nitrogen removal in the anoxic zones of the open ocean. Anammox requires a source of ammonium, which under anoxic conditions could be supplied by the breakdown of sinking organic matter via heterotrophic denitrification. However, at many locations where anammox is measured, denitrification rat...
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 dive depth in penguins in relation to diel vertical migration
Diel vertical migration by zooplankton is thought to allow manne animals to exploit the more abundant food resources in the upper water strata at night while minimizing predation from optically orientating predators. Contrary to this, consistantly shallower dives at night made by marine reptiles, mammals, and birds have been attributed to enhanced feeding conditions as predators exploit prey th...
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...
