Diel vertical migration of the Southern Ocean euphausiid, Euphausia triacantha, and its metabolic response to consequent short-term temperature changes
Diel vertical migration is a widespread behaviour amongst zooplankton, yet its effect on the rate at which individuals respire remains poorly understood. To address this, we investigated the effect of short-term temperature change on the respiration rate of Euphausia triacantha, a common component o...

Diel vertical migration is a widespread behaviour amongst zooplankton, yet its effect on the rate at which individuals respire remains poorly understood.

We found respiration to vary in response to size, with a value of 0.84 for the scaling coefficient, b. When scaled to b, respiration varied strongly in response to transitory temperature change, ranging from 0.37 to 1.65 µl O2 mg dry weight (DW)-b h-1 between 0.17 and 4.74°C, resulting in a Q10 of 3.6.
