“…2c and 3a). Similar results have been reported for other spruce forests (Nilsen and Strand, 2008;Vranova et al, 2009) and other forest ecosystems (Brumme, 1995;Sullivan et al, 2008;Tang et al, 2005b). Reductions in R s rate by forest thinning are linked to thinninginduced changes in microclimate (Galhidy et al, 2006;Gray et al, 2002), substrate availability (Selig et al, 2008;Zu et al, 2009), soil microbes (Arunachalam and Arunachalam, 2000;Zhang and Zak, 1998), and fine roots (Peng and Thomas, 2006;Tang et al, 2005b).…”

“…For example, Vranova et al (2009) had reported that higher intensity of thinning decreased total carbon content and C/N in the Ae horizon under young Norway spruce stands. Also, Vesterdal et al (1995) had found significant reduction in organic layer carbon due to heavy thinning of Norway spruce stands in Denmark.…”

A clear-cutting system with soil preparation before replanting is usual for Scots pine stands in many European countries. Additionally, thinning regimes are applied during the rotation. Thus, forest floor is recreated in each rotation and can be influenced by thinning regime. The present study aimed to determine possible effects of thinning on production (evaluated by basal area) and forest-floor status (evaluated by dry mass, carbon and nitrogen content) in pine stands. We used data from four experiments established in 1962 in 25- to 45-year-old pine stands. In 2008, we analysed forest-floor characteristics under the observed stands. The results from basal area evaluation showed different development in treatments on all experiments during and at the end of observation. We observed substantial, but statistically non-significant, differences between treatments in quantity of dry mass (and of carbon and nitrogen) accumulated in humus horizons under Scots pine stands more than 40 years after first thinning.

“…In previous studies was found higher C-mineralization and microbial biomass on abandoned meadow compared to its moderatelly mown counterpart (Kafka, 2005;Vranová et al, 2009a). On the other hand, the amount of C ox and N t was quite a similar on both of the meadows including relative stand heterogeneity (Coeffi cient of Variation in % determined within whole plots) of these soil characteristics in studied Ap horizon; only, slightly favourable C/N ratio was observed on the abandoned meadow horizon (Vranová et al, 2007).…”

This work was aimed at determination of the effect of 13 years abandonment of previously long-term mown mountain meadows on uptake of L-glutamic acid (14CO2H[14CH2]2[NH2]14CO2H) and L-alanine (14CH314CH[NH2]14CO2H) by microbial community of Ap horizon (3–13 cm). The study plots has been located near to the experimental stand “Bílý Kříž“ which is located in the Moravian-Silesian Beskids Mountains (N 49°30’17”, E 18°32’28”), on a slope with an elevation of 825–860 m a. s. l. and southeast orientation, and soil classified as an Oxyaquic Hapludalf. The study was performed to test method for measurement of 14C-labelled amino acids uptake by soil microbial community and to increase knowledge on particular processes of N-transformation in soil of these ecosystems. The results obtained in this work showed that 13 years abandonment of mountain meadow did not significantly (P > 0.05) influence rate of glutamic acid or alanine uptake by soil microbial community. Further research including determination of amino acids use by soil microbial biomass with expression of their partitioning between production of new microbial biomass and energy metabolism is necessary.
