  abstract = {{Q}uantification of microbial activities involved in soil organic carbon ({SOC}) decomposition is critical for the prediction of the long-term impact of climate change on soil respiration ({SR}) and {SOC} stock. {A}lthough the temperature sensitivity of {SR} is especially critical in semi-arid regions, such as {N}orth {W}est {T}unisia, where the {SOC} stock is low, little research has been carried out in these environments. {M}ore needs to be known about factors, such as {SOC} availability that influence temperature sensitivity. {I}n this study, soil samples were incubated with and without glucose addition for 28 days after a 28-day pre-incubation period. {P}re-incubation and incubation was carried out at 20 degrees {C}, 30 degrees {C}, 40 degrees {C} and 50 degrees {C}. {R}espiration measurements were taken with temperature, glucose addition and incubation time as independent variables. {T}he highest pre-incubation temperature reduced the temperature sensitivity of {SR} during the subsequent incubation period, both with and without glucose addition. {S}oil samples pre-incubated at 50 degrees {C} had the lowest {SR} at all subsequent incubation temperatures and the lowest temperature sensitivity of {SR}, even after glucose addition. {H}owever, after glucose addition, the effect of a high pre-incubation temperature on soil respiration lasted only two days. {M}easuring the water-soluble carbon ({WSC}) in soil samples suggested that the high pre-incubation temperature may have killed part of the microbial biomass, modified microbial communities or solubilized {SOC}. {F}or quantifying the possible effect of global warming, in particular heat waves, on soil respiration in the soil studied, the results indicate a moderate response of soil respiration to temperature at high temperatures, as shown by {Q}(10) close to 1.7, even in the range 40-50 degrees {C}.},
