Protocols for the in vitro propagation of two endangered plant species in the Czech Republic, Gentiana verna L. and Jurinea cyanoides (L.) Rchb., were established. In G. verna, the induction of organogenesis on vegetative shoots was successful on the basal 6% agar WPM medium with 200 mg.l-1of glutamine, 200 mg.l-1 of casein hydrolysate, 30 g.l-1 of sucrose, 0.2 mg.l-1 of BAP, and 0.1 mg.l-1 of IBA. The multiplication of primary explants was achieved on 6% agar basal MS medium with the same concentrations of substances mentioned above. In J. cyanoides,...

The numbers of nontarget arthropods captured by Theysohn pheromone traps (TPTs) and insecticide-treated tripod trap logs (TRIPODs) were compared; both kinds of traps were baited with pheromone lures Pheagr IT for Ips typographus. In 2010, 15 TPTs and 15 TRIPODs were deployed (with a 10-m spacing) in a forest in the northeastern Czech Republic. The TPTs and TRIPODs were inspected weekly during the entire period of I. typographus flight activity (30 April-1 October). The TRIPODs were sprayed with Vaztak 10 SC insecticide every 7 weeks; at each spraying, the pheromone evaporators were renewed. Higher numbers of entomophagous arthropods,...
Establishing windbreaks: how rapidly do the smaller tree transplants reach the height of the larger ones?Original Paper

The aim of this study is to identify a period of time over which smaller, less costly tree transplants can reach the height of larger tree transplants and thus offset their performance. The following Central European native tree species were used: Quercus robur L., Carpinus betulus L., Fraxinus excelsior L., Acer campestre L., Acer pseudoplatanus L., Tilia cordata Mill. and Prunus avium L. In the period after planting, the best growth was observed for small tree transplants. These transplants reached the height of the medium-sized tree transplants for all species except C....
Microsatellite DNA markers in Shorea platyclados (Dipterocarpaceae): genetic diversity, size homoplasy and mother treesOriginal Paper

Cross-specific amplification of microsatellite loci greatly enhances the effectiveness of this marker system. This shortcut would greatly enhance our examination of the gene flow and population structure of trees in diverse tropical rainforests. To explore the effectiveness and limitations of this approach, we examined allelic diversity at six microsatellite loci, originally developed in a congeneric species, in three populations of Shorea platyclados from Peninsular Malaysia. Fragment sizing was performed by an efficient and sensitive (1 bp resolution) technique using capillary electrophoresis, ethidium bromide detection, and minimal clean-up....
The impacts of ground-based logging equipment on forest soilOriginal Paper

Soil properties can be affected by heavy equipment used for skidding but these impacts vary greatly with site conditions and operational practices. We assessed the effects of ground-based skidding on site disturbance and soil physical properties. We also tested the effects of skid trail slope and traffic frequency on soil compaction, total porosity, and moisture content. On average, about 30% of all harvested area was disturbed to varying levels. Intact forest floor (undisturbed) and light slash were the dominant surface conditions, covering an average of 68.9% of harvested area. Deep disturbed soils accounted for only just over 1.1% of observations....
Occurrence of frost episodes and their dynamics in height gradient above the ground in the Jizerské hory Mts.Original Paper

We have verified whether the temperatures in the zone of terminal leaders of saplings (+100 cm) were less extreme than the temperatures in the zone of terminal leaders of common-sized planting stock (+30 cm). In May and June of 2011 and 2012 we investigated the occurrence of late frosts at different levels above the ground. The number of days and amount of hourly frost records were counted and the sum of sub-zero temperatures was calculated. Our study confirmed that sub-zero temperatures mostly occur at levels near the ground. Therefore, on the sites exposed to late frosts, such as mountain frost hollows, in addition to common-sized planting stock...
Management of mountain forests in the hydrology of a landscape, the Czech RepublicReview

Forests important from a water-management perspective cover 723,000 ha of the Czech Republic (CR), i.e. 27.6% of the forest area. These forests play an important role especially in a mountain landscape. Forests decrease peak flood flows, compensate water discharge and represent a source of high-quality fresh water. The optimum hydrological function is provided by forests that are healthy, ecologically stable, diversified, proper to site, growing on a good forest soil, managed by small-area felling and emulating natural processes. For mountain sites of the CR, the optimum proportion of Norway spruce (+ Silver fir) ranges from 70 to 80% and of European...
