Oxygen consumption of Limnocalanus macrurus Sars (Calanoida, Copepoda) in relation to environmental conditions
The oxygen consumption of Limnocalanus macrurus and its relationship to a number of environmental parameters were determined on specimens from two arctic lakes, both in the laboratory and in situ. The Q 10 from 0 to 10 °C was 1.93 and from 5 to 15 °C was 2.20. The respiration rate increased shortly...
