DESCRIPTION:Ectomycorrhizal (ECM) fungi contribute significantly to ecosys
 tem respiration\, but unlike for their host plants\, little research has a
 ddressed the effect of temperature on ECM fungal respiration. Rapid temper
 ature\nchanges can be expected in forests on a weekly and seasonal basis a
 nd can be anticipated in the coming years on account of global warming.\n\
 nWe examined acclimation to temperature of respiration by ECM fungi and fo
 und that substantial variation exists among ECM fungal isolates in their a
 bility to acclimate to temperature.  As soil temperatures increase\, ECM f
 ungi that acclimate may require less carbon from their host plants than fu
 ngi that do not acclimate. The ability of some ECM fungi to acclimate may 
 partially ameliorate the anticipated positive feedback between soil respir
 ation and temperature.
