Instantaneous incubation responses change depending on prior temperature. This change does not correspond to biomass size and is larger in Arctic/boreal soils and smaller in agricultural soils. One of my personal favorite incubation studies, this is a clever use of a single cooling-warming incubation cycle over the course of several months.
