Opis:
Results of research on the process of spontaneous overgrowth of subalpine forest glades in the Gorce National Park are presented in the paper. Research was carried out in 2006-2008. The condition and directions of changes of glades undergoing conservation efforts of different intensity were examined.

Opis:
The aim of this article is to establish how land use change influences soil organic matter content in the loess landscape. The research was conducted near Krasnystaw in the Lublin Upland, in forest, on arable land and on abandoned lands at various stages of secondary succession. During the field research, samples were collected from the upper soil layer and analyzed for organic carbon content, fractional composition of humus compounds and soil reaction. The results obtained indicate that the impact of land use change manifests itself in a change of the soil reaction, which turns from neutral or slightly acid into acid. The tillage system reduces organic matter in the soil and increases the humic acids ratio, whereas abandonment of the land causes an evident increase in the soil’s organic matter content and the fulvic acids ratio. These results allow us to state that land use change has a rapid impact on the geochemical properties of the landscape (which can be noticed as soon as 5 years after the land is abandoned).

Opis:
Plant succession is quite a common phenomenon in Poland, especially in agricultural landscapes. At the turn of the 21st century there was a significant increase in the area of fallow lands. That increased the area occupied by ruderal and segetal vegetation. The development of vegetation on post-agricultural lands transforms soils. The aim of this paper is to determine changes in vegetation and soil properties that occur as a result of secondary succession on post-agricultural lands in loess landscapes

Opis:
Volatile compounds are very important to the flavour and quality of the wine. The study aimed to determine the effect of grape variety (Rondo and Zweigelt), yeast, malolactic fermentation (MLF) and yeast×MLF interaction on the content of volatile compounds in red wines. The wines were produced by sequential inoculation with five commercial yeast strains and a commercial lactic acid bacteria (LAB) strain (induced malolactic fermentation) as well as by inoculation with five commercial yeast strains and without LAB inoculation (spontaneous malolactic fermentation). The volatile compounds were determined by headspace solid-phase microextraction/gas chromatography-mass spectrometry (HS-SPME-GC/MS). Forty-six volatile compounds belonging to alcohols, esters, acids, aldehydes, ketones, furan compounds, sulfur compounds and volatile phenols were identified in the wines. The grape variety was the factor with a significant impact on the highest number of volatile compounds, 32 out of 46. Furthermore, 7 compounds were affected by yeast, 10 by MLF and only 3 by yeast×MLF interaction. Characteristic bands in Fourier transform infrared (FTIR) spectra were assigned to the vibrations of functional groups of volatile compounds. The whole FTIR spectra were analysed in detail; three characteristic spectral ranges for different classes of volatile compounds such as 3650-2700, 1750-1500, and below 1500 cm-1 were shown. The most remarkable spectral changes were observed for the last two areas.
