Table 1.

Table of means (±SD) for daily microclimatic parameters at the forest edge and interior, with T_min, minimal temperature (°C); T_max, maximum temperature; T_amp, temperature amplitude; RH_min, minimal RH (%); and rel. light, relative light intensity (%). Means were compared via Student's t-test. Days of observation were grouped into different weather categories with reference to the minimal daily RH outside the forest, with <50 % for sunny, <60 % for overcast and >60 % for wet days.
