Abstract
Hartley et al. question whether reduction in Rmass, 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 cannot alone explain observed responses, and
urge caution in the interpretation of the seasonal data.
