The use of simple models containing traditional equations to describe tree growth is common. However, equations that incorporate different factors (e.g. site quality of the stands, crown classes of the trees, silvicultural treatments) may improve their accuracy in a wide range of stand conditions. The aim of this work was to compare the accuracy of tree diameter growth models using (i) a family of simple equations adjusted by stand site quality and crown class of trees, and (ii) a unique global equation including stand and individual tree variables. Samplings were conducted in 136 natural even-aged Nothofagus antarctica (Forster f.) Oersted stands in Southern Patagonia (Argentina) covering age (20-200 years), crown class and site quality gradients. The following diameter growth models were fitted: 16 simple equations using two independent variables (age and one equation for each stand site quality or crown class) based on Richards model, plus a unique global equation using three independent variables (age, stand site quality and crown class). Simple equations showed higher variability in their accuracy, explained between 54% and 92% of the data variation. The global model presented similar accuracy like the better equations of the simple growth models. The unification of the simple growth models into a unique global equation did not greatly improve the accuracy of estimations, but positively influenced the biological response of the model. Another advantage of the global equation is the simple use under a wide range of natural stand conditions. The proposed global model allows to explain the tree growth of N. antarctica trees along the natural studied gradients.

Quality of surface corresponds to the scale from middle smooth milling to rough milling. It shows the results of undulation in dependence on technical and technological parameters ‒ feed rate and abrasive mass flow. The paper also contains the methodology for assessment of the effect of these parameters on surface finished undulation. Our paper presents significant results of experiments made by this methodology applied to MDF, OSB boards and to technical beech plywood. We can see from the above-mentioned results that the fundamental indicator for roughness assessment is the arithmetical mean deviation of roughness profile Ra. MDF boards have the most homogeneous structure in the entire cut among the monitored materials, which affects the insignificance of parameter Ra. For OSB boards, we can see the worse surface quality with higher feed rate and vice versa for plywood, higher feed rate improves the surface quality. A higher amount of abrasive flow causes the worse surface quality.

In total, seven micromammalian species were detected. Of them, only three species were captured within the forest interior, whereas six species were recorded on the clearing. Apodemus flavicollis and Clethrionomys glareolus were dominant species. Another five species were recorded scarcely. Abundance of Apodemus flavicollis reached significantly (P < 0.001) the highest value in the forest interior. On the contrary, Clethrionomys glareolus was significantly (P < 0.001) attracted by the clearing. The distribution of two dominant rodent species probably reflected the high beechnut supply in the given period. The relationships between food supply and microhabitat preferences of Apodemus flavicollis and Clethrionomys glareolus were discussed.

Rhytisma acerinum (Pers.) Fries is an ascomycete that forms black stromata known as tar spot on the adaxial surface of the leaves of Acer species. The tar spot (R. acerinum) disease has been increasing in incidence and severity in maples of Hyrcanian forests, northern Iran, in recent years. One of the best ways to manage infestations by R. acerinum is through adequate biotechnical techniques. The isolation of fungal spore colonies was evaluated using different dosages of Oxywet 10% (50, 100, 200, 500 µl), Gentamicin 5% (100, 200, 400; 1,000 µl), and Amoxicillin antibiotics 20% (25, 50, 100, 250 µl) in 100 ml of distilled water in each treatment. All possible combinations of single doses were applied using light and dark treatments. In light conditions, it appears that the Oxywet (200 µl) had the significant effect on controlling R. acerinum. Reduced fungal growth, coefficient and inhibition of fungal growth were observed in the light treatment. The other antibiotics (Gentamicin, Amoxicillin) were not so effective in controlling this pathogen. Results of spore germination showed a significant difference between all treatments. All treatments were tested in pure cultures in the laboratory only. The results obtained cannot be expected of the same effectiveness in open field trials.

Many areas of mountain forests in Europe have been affected by human activities such as felling and livestock grazing in the past and then left for natural succession. Those forests provide several ecosystem services (e.g. soil or avalanche protection) and therefore it is vital to know their developmental processes. The Norway spruce forest stand in the area of Medvědí Mt. (Šumava National Park, Czech Republic), known as the Jewish Forest, is considered an example of succession after anthropogenic disturbances. This study aimed to: (1) analyse the history of disturbances which affected the locality, (2) describe the subsequent process of forest succession which led to the development of the present forest formation. We conducted a dendrochronological analysis and a spatial analysis. The main cohort was established after a period of disturbances in the first half of the 20th century. Both natural (windstorm) and anthropogenic (logging and livestock grazing) disturbances coincided during this period. Regeneration of low density was restricted to a short period after the disturbance and was likely dependent on the occurrence of proper microsites. Later, regeneration was probably obstructed by lack of convenient microsites and high competition of the herb layer. Nowadays, new regeneration emerges together with proper microsite at decaying wood and near mature trees. We conclude that anthropogenic disturbances can limit the density and heterogeneity of regeneration, which leads to the establishment of sparse stand. This structure can persist for decades before proper microsites accumulate and enable regeneration. Keywords: dendroecology, disturbance history, grazing, logging, Picea abies (L.)

Once per week monitoring was carried out from late April to early October. During the sample collection process, an occurrence of Scobicia chevrieri (Villa & Villa 1835) from the Bostrichidae family has been recorded. It is considered to be the first record of this powderpost beetle species in the Slovak Republic. An imago was caught in a light trap which uses UV tubes in combination with white light. Its potential host plant seems to be Quercus robur L., or other Quercus species found in the Mlyňany Arboretum of SAS.
