  • Whole animal total metabolism is used in all estimates of Pcall.

  • a Calling RQ has not been measured in these species. Forrest (1991) assumed RQ=0.85.

  • b Efficiency values in parentheses for O. quadripunctatus are based on the maximum Pac values measured by Forrest (1991) in individuals calling from a leaf baffle and by assuming Pcall from Prestwich and Walker (1981) for crickets not calling in a baffle.

  • c This power output corresponds to the highest value typically observed in the field in burrows whose walls are saturated with water.
