Sažetak
The microclimatic differences (based on field measurements) and topoclimatic differences (based on digital terrain model) between phytocenoses in the sinkhole were tested and interpreted statistically. The results correspond to previous assumptions regarding climatic differences among phytocenoses. The relation between the microclimate and the topoclimate was examined. insolation quantity significantly correlates with air temperature (positively) and relative air moisture (negatively), only after weighting by the relative illumination in the forest phytocenosis. The first principal component of the soil temperature daily dynamics at four soil depths is not correlated with the other variables, reflecting the particularity of the thermic process in the soil. The impact of two important causes of thermicdifferences between phytocenoses was distiguished. The daily air temperature dynamics is basically conditioned by insolation and the nightly temperature dynamics is conditioned by altitude in the sinkhole.
