Effect of temperature on zooplankton vertical migration velocity

fourier migration for vertical velocity variations

the stolt (f-k) migration algorithm is a direct (i.e. non-recursive) fourier-domain technique based on a change of variables (or equivalently, a mapping) that converts the input spectrum to the output spectrum. the algorithm is simple and efficient but limited to constant velocity. a v(z)(f-k) migration method, capable of very high accuracy for vertical variations of velocity, can be formulated...

The adaptive significance of diel vertical migration of zooplankton

Many taxa of both marine and freshwater zooplankton perform diel vertical migrations with amplitudes from a few to 100 metres (Hutchinson, 1967). The 'normal' pattern is an evening ascent and a morning descent, though several cases of 'reversed' migrations have been described (Ohman, Frost & Cohen, 1983; Bayly, 1986). Migrating animals spend the day in deep waters but stay near the surface at n...

Diel 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...
