Geomorphologic Analysis of the Javoří Hory Mountains Relief

Javoří hory Mountains is a part of Intra Sudetic Basin that belongs to the Permian-Carboniferous section of the Bohemian Massif, whose geological evolution was strongly influenced by volcanic activity. In the Pleistocene epoch cryogenic processes modeled the mountains significantly (frost cliffs, gelifluction streams), which resulted, in connection to the slope orientations, in substantial moun...

Study of macroscopic markers of Norway spruce damage in the Krušné Hory Mts

Monitoring physiological status of Norway spruce trees in the Krušné hory in 2000: selected metabolic, histochemical and spectral analyses

The massive decline of Norway spruce ( Picea abies (L.) Karst) has been observed in the Krušné hory during the last few decades. Before macroscopic changes occur (e.g . needle yellowing and foliar lost), the effect of stress factors is initially recognisable as the metabolic and microscopic changes. Phenolics compounds , lignin and photosynthetic pigments seem to be good indicators of needle pr...

Visible foliar injury as a tool for the assessment of surface ozone impact on native vegetation: a case study from the Jizerské hory Mts

Surface ozone is considered to be a very phytotoxic gaseous air pollutant. Its negative impacts at both the cell and the organ level have been shown, mainly as a result of experiments. However, the demonstration of ozone negative impacts on native plants is not explicit. An assessment of ozone impact on vegetation and ecosystems using indicators based on ambient ozone concentrations is insuffic...

Ungulate Impact on Natural Regeneration in Spruce-Beech-Fir Stands in Černý důl Nature Reserve in the Orlické Hory Mountains, Case Study from Central Sudetes

The paper presents the results of a study on tree regeneration of forest stands in the Černý důl Nature Reserve, which is situated in the Orlické hory Mountains Protected Landscape area in the Czech Republic. Research was conducted in a spruce-beech stand with an admixture of silver fir, sycamore maple and rowan on two comparative permanent research plots (PRPs) (PRP 1—fenced enclosure and PRP ...
