Submersion
- Drivers of the dive response in trained harbour porpoises (Phocoena phocoena)
Summary: Harbour porpoise diving bradycardia is initiated with blowhole submergence rather than apnoea alone, while surface tachycardia is only fully obtained with lung ventilation, yet initiated anticipatorily.
- The closed spiracle phase of discontinuous gas exchange predicts diving duration in the grasshopper Paracinema tricolor
Summary: The ability to tolerate periods of spiracular closure in Paracinema tricolor grasshoppers can facilitate predation avoidance via diving or be used for exploiting underwater resources.
