Don] Lindl.) Abstract: The aim of the study is to evaluate the role of the Grand fir (Abies grandis [Dougl. ex D. Don] Lindl.) as a soil-improving species in the area of the University Training Forest in Kostelec nad Černými lesy, Jevany district. The state of humus forms in the stand part with Grand fir was compared with the mature Norway spruce (Picea abies [L.] Karst.) without regeneration, with young beech (Fagus sylvatica L.), Norway spruce (Picea abies [L.] Karst.) and oak (Quercus spp. L.) stands (all of pole stage). The site is characterized as 4P1 - acid oak-fir site with Luzula pilosa, the geological bedrock is formed of cretaceous sandstone with loess overlays, the soils are Luvisols, the terrain is flat at the altitude of 420-440 m a.s.l. The humus form samples (L, F, H, Ah horizons) were taken in 4 replications, quantitatively for the holorganic layers. The dry mass amount and total nutrient contents were analyzed for holorganic horizons, the basic pedochemical characteristics (pH, soil adsorption complex characteristics, exchangeable acidity and exchangeable nutrients) were determined for all horizons. The results confirmed marked and positive effects of the Grand fir litter on the surface layer characteristics. This tree species supports the litter of good composition, transforming easily and forming humus forms of higher quality compared to coniferous as well as studied broadleaved species.

Abstract: Top-soil samples were taken from four mountain forest ecosystems in the Bohemian Forest to compare the processes in European beech-mixture (Fs) and Norway spruce (Pa) dominating ecosystems. Selected plots can be grouped into two types of forest ecosystems which are conditioned by position on the natural altitudinal gradient. Several chemical features (content of organic matter, properties of humic and fulvic acids, releasable P, Ca, Mg, Fe and Al content) were compared with the species structure of oribatid mite communities in the same samples. Strict differences between both ecosystem types were discovered. Statistically significant differences were detected in Mg content (0.42 mg/g in Fs ecosystems compared to 0.30 mg/g in Pa ecosystems) and in organic matter quality (the ratio of carbon content in humic acids to carbon content in total humus acids was 0.53 in Fs ecosystems and 0.66 in Pa ecosystems) and quantity (e.g. content of humic acid carbon was 59 and 86 mg/g in Fs and Pa ecosystems, respectively). Different dynamics of organic matter decomposition and nutrient movement lead to some opposite correlations among the soil chemical features: correlation between total ash and soluble ash (r = +0.96 and -0.86 in the Fs and Pa ecosystems, respectively) and total ash - P content correlation (r = +0.76 and -0.92 in the Fs and Pa ecosystems, respectively) can be mentioned as examples. The oribatid mite communities are markedly distinct in both ecosystem types, although parameters of species diversity and abundance are similar. Different correlations were revealed between the parameters of mite community structure (e.g. species diversity and total mite abundance) and top-soil chemical features. The correlation structure is different in both ecosystem types. It indicates differences in leading variables determining the oribatid community structure in the beech mixture ecosystem or in the Norway spruce one.

Our study was focused on Norway spruce (Picea abies [L.] Karst.) and European beech (Fagus sylvatica L.) grown in an acidic soil where acidity was caused by past air pollution in the Kysucké Beskydy Mts., North-Western Slovakia. Between April and October 2006, the following fine root traits were studied: biomass and necromass seasonal dynamics, vertical distribution, production, mortality, fine root turnover and production to mortality ratio. Sequential soil coring was repeatedly implemented in April, June, July, September, and October including the soil layers of 0-5, 5-15, 15-25, and 25-35 cm. Results indicated that spruce had a lower standing stock of fine roots than beech, and fine roots of spruce were more superficially distributed than those of beech. Furthermore, we estimated higher seasonal dynamics and also higher turnover of fine roots in spruce than in beech. The production to mortality ratio was higher in beech than in spruce, which was hypothetically explained as the effect of drought episodes that occurred in July and August. The results suggested that the beech root system could resist a physiological stress better than that of spruce. This conclusion was supported by different vertical distributions of fine roots in spruce and beech stands.

The plot was originally established in the 30's of the 20th century. The tree layer is dominated by European beech (Fagus sylvatica L.), with Silver fir (Abies alba Mill.) and Norway spruce (Picea abies [L.] Karst.) as often associated species, and with sycamore maple (Acer pseudoplatanus L.) growing occasionally in small groups. After 70 years, the tree species composition partly changed. Total live timber volume increased from 529.6 to 636.3 m3/ha. Considerable growth was recorded in beech, while the live timber volume of fir, spruce and sycamore maple did not almost change. Total number of trees (> 3 cm in dbh) increased from 737 trees/ha to 760 trees/ha. Number of beech trees increased markedly. On the contrary, fir and spruce showed a significant decrease in tree number. Interesting results emerged from the renewal of the permanent square plot (20 × 20 m), proving that beech is able to persist in the shade for more than 70 years with only minimal increment of both height and diameter.

Sampling was undertaken between April and October on 3 oak species (Quercus robur, Q. petraea, Q. rubra). Biological traits of larvae were examined in order to explain differences in seasonal guilds among oaks. Communities varied in structure and abundance. Species richness in four seasonal guilds (flush, late spring, summer and autumn feeders) had a similar pattern on each of the studied oak species. The guild of flush feeders had the richest species assemblage, followed by the late spring feeder guild and both guilds were significantly richer than the summer feeder guild and autumn feeder guild.
