... 2 consumption is calculated from electrolytic charge transfer. The effects of developmental stage, body mass and temperature on O 2 consumption of Tenebrio molitor beetles were easily measured by the apparatus. This straightforward design is a significant innovation in that it provides continuous...

... circadian cycles, each consisting of a less-responsive and more-responsive period, in a circabidian oscillation, and the circabidian rhythm is driven by the circadian clock. A mark–recapture study showed that beetles repeatedly appeared on the same tree approximately every 2 days. However, the periodicity...

...Roger S. Seymour; Craig R. White; Marc Gibernau SUMMARY Cyclocephala colasi beetles are facultative endotherms that spend most of their adult lives inside the inflorescences of Philodendron solimoesense , where ambient temperature ( T a ) averages about 28°C due to floral thermogenesis...

... compressions are associated with excurrent gas exchange in the ground beetle Pterostichus stygicus , we used flow-through respirometry and synchrotron x-ray phase-contrast imaging to simultaneously record CO 2 emission and observe morphological changes in the major tracheae. Each observed tracheal compression...

...T. Eimüller; P. Guttmann; S. N. Gorb SUMMARY For the first time, the terminal elements (spatulae) of setal (hairy)attachment devices of the beetle Gastrophysa viridula (Coleoptera,Chrysomelidae) and the fly Lucilia caesar (Diptera, Calliphoridae)were studied using transmission X-ray microscopy...

...Marcus J. Byrne; Frances D. Duncan SUMMARY The role of the subelytral cavity in flightless beetle species as an adaptation to water saving in arid habitats is still in dispute. We found that relatively little CO 2 was released from the subelytral cavity of a large apterous beetle Circellium bacchus...
