Abstract. We measured nitrogen oxides (N2O and NOx), dinitrogen (N2) and carbon dioxide (CO2) emissions from a spruce-fir-beech forest soil in the North Tyrolean limestone Alps in Austria. The site received 12.1 kg nitrogen via wet and dry deposition. Fluxes of nitric oxide (NO) were measured by an automatic dynamic chamber system on an hourly basis over a two year period. Daily N2O emissions were obtained by a semi-automatic gas measuring system. In order to cover spatial variability biweekly manual measurements of N2O and CO2 emissions were carried out, additionally. For acquiring information on the effects of soil and meteorological conditions and of N-deposition on N-emissions we chose the autoregression procedure (time-series analysis) as our means of investigation. Hence, we could exclude the data's autocorrelation in the course of the time. We found that soil temperature, soil moisture and wet N-deposition followed by air temperature and precipitation were the most powerful influencing parameters effecting N-emissions. With these variables up to 89% of observed temporal variations of N-emissions could be explained. During the two-year investigation period between 2.5 and 3.5% of deposited N was reemitted in form of N2O whereas only 0.2% were emitted as NO. At our mountain forest site the main end-product of microbial activity processes was N2 and trace gases (N2O and NO) were only of minor importance.

The spectrum and occurrence of entomopathogenic fungi in litter beech forest. meadow soil and arable soil were evaluated using an "insect bait method". Soil and litter samples taken in autumn and spring from each stand were baited with <i>G. mellonella</i> larvae at 22°C. Six species of entomopathogenic fungi infected these larvae. In the litter <i>Beauveria bassiana</i> was the dominant species. Besides <i>B. bassiana</i>, 23% of <i>G. mellonella</i> larvae were infected by <i>Paecilomyces farinosus</i> in autumn. In the forest soil the dominant entomopathogenic fungus was not found. In this stand the number of infected larvae was the lowest. <i>Metarhizium anisopliae</i> was the dominant species in the meadow soil in both sampling periods. In the soil taken from a rye field<i> P. fumosoroseus</i> and <i>B. bassiana</i> infected <i>G. mellonella</i> larvae almost to the same degree. It was established that <i>B. bassiana</i> and <i>M. anisopliae</i> infected more <i>G. mellonella</i> larvae in spring than in autumn. In the case of <i>P. farinosus</i> and <i>P. fumosoroseus</i> an opposite tendency was observed.
