摘要

The discontinuous gas exchange (DGE) pattern of respiration shownudby many arthropods includes periods of spiracle closure (C-phase)udand is largely thought to serve as a physiological adaptation to restrictudwater loss in terrestrial environments. One major challenge to thisudhypothesis is to explain the presence of DGE in insects in moistudenvironments. Here, we show a novel ecological correlate of theudC-phase, namely, diving behaviour in mesic Paracinema tricolorudgrasshoppers. Notably, maximal dive duration is positively correlatedudwith C-phase length, even after accounting for mass scaling andudabsolute metabolic rate. Here, we propose that an additionaludadvantage of DGE may be conferred by allowing the trachealudsystem to act as a sealed underwater oxygen reservoir. Spiracleudclosure may facilitate underwater submersion, which, in turn, mayudcontribute to predator avoidance, the survival of accidental immersionudor periodic flooding and the exploitation of underwater resources.
