Respiratory patterns and metabolism in tenebrionid and carabid beetles from the Simpson Desert, Australia

  title={Respiratory patterns and metabolism in tenebrionid and carabid beetles from the Simpson Desert, Australia},
  author={Frances D. Duncan and Christopher R. Dickman},
The respiratory physiology of four species of Australian desert-dwelling beetle was examined using a flow-through respirometry system over the temperature range of 20–40°C. The two species of tenebrionid beetles (Heleus waitei and Pterohelaeus sp.) did not exhibit the discontinuous gas exchange cycles (DGC), a mechanism to possibly reduce respiratory water loss rates, observed in other arid-dwelling beetles. There were small increases in metabolic rate with temperature resulting in a Q 10 of 1… CONTINUE READING
