Hartley et al. question whether reduction in R mass , under experimental warming, arises because of the biomass method. We show the method they treat as independent yields the same result. We describe why the substrate‐depletion hypothesis may not solely explain observed responses, and urge caution in interpretation of the seasonal data.
