Analysis of 148 measurements of individual respiration rate showed that although respiration was linearly related to live weight on a double log10 scale, there were significant differences between rates at o°, + 50 and +10 °C. Proto- and deutonymphal metabolic rates were higher than other stages, es...

Summary: | Analysis of 148 measurements of individual respiration rate showed that although respiration was linearly related to live weight on a double log10 scale, there were significant differences between rates at o°, + 50 and +10 °C. Proto- and deutonymphal metabolic rates were higher than other stages, especially at +10 °C. Q10 values ranged from 2-07 to 3-83 over o ° to +10 °C. Equations relating individual respiratory rate to live weight and temperature for A. antarcticus, and metabolic rate to temperature for 10 species of Antarctic terrestrial invertebrates were developed. Comparison with tem-perate data indicated considerable cold adaptation in the Antarctic species with 3-5 times increased metabolism. It was calculated that 78—82 % of the energy assimilated may be used in respiration by A. antarcticus. |
