but the amount of fungal biomass in soil was expected to differ
(May and August) were preliminarily selected based on the results
obtained during a previous, independent sampling performed at
the same site in the preceding year (ˇSnajdr et al., 2008b). The temperatures
at the soil surface were monitored using a Testo 175 H
(Testo, Germany) data logger with six reads per hour to select a
time period well representative of the means and circadian temperature
changes typical of either spring and late summer and to
avoid the effect of climatic extremes.
