Fluctuating asymmetry (FA) has been suggested as a measure of the sensitivity development to wide array genetic and environmental stresses. It also that antlers in red deer could be important during social rutting displays. We used antler measurements 51 males were measured over subsequent seasons, from 3–8 years age, analysed three traits: weight, length, number tines (antler size). calculated absolute relative FA. All size traits highly significantly intercorrelated. By contrast this, FA...

Two soils contaminated by toxic elements differing in long-term contamination were compared a microcosm experiment for changes microbial community structure and respiration after various treatments. We observed that the extent of (over 200 years) did not change total numbers diversity bacteria but influenced composition. Namely, Actinobacteria determined specific qPCR increased also proportion Chloroflexi Illumina sequences more soil. In experiment, secondary disturbance supplemented cadmium...

We studied the effects of magnesium (Mg) NPK fertilizer applied in 2000 to maturing Norway spruce (Picea abies /L./ Karst.) stands with yellowing symptoms and situated on poor acidified soils Šumava mountains (the Czech Republic). Long-term defoliation, nutrient content foliage diameter increment were evaluated three specific variants: trees, trees without fertilized trees. The results indicate differences soil characteristics, radial growth response climate. Fertilization increased Mg base...

This article describes the current situation in area of electronic warfare. Aircraft protection can be greatly utilised not only military but also civilian applications. Active radar signal jamming methods are costly and therefore, aircraft using Chaff increases efficiency, application variability makes it affordable. However, use is restricted or even forbidden many countries due to its environmental risks caused by applied materials. Article computing RCS development air volume. Also...

The relationship between vegetation and selected soil characteristics in different monoculture forest types was investigated as part of a landscape restoration project after brown coal mining. Six were selected: alder (Alnus sp.), spruce (Picea pine (Pinus larch (Larix long-term deciduous (Quercus robur, Tilia created by spontaneous succession. These stands classified into two age categories (younger older). attributes, C/N, TC, TN, pH, A horizon depth assessed. observed species categorized...

Abstract The spoil heaps from brown coal mining without technical reclamation are interesting specific sites for ecological relationships observation. This research was aimed at investigating whether topographic features, which determine soil nutrient and moisture distribution, in combination with fauna (wireworm earthworm) presence, affect plant community composition a spontaneously revegetated post area an undulating surface. Two of different age three types features were selected,...

Abstract. Lesni Potok stream drains a forested headwater catchment in the central Czech Republic. It was artificially acidified with hydrochloric acid (HC1) for four hours to assess role of substrate acid-neutralisation and recovery. The pH lowered from 4.7 3.2. Desorption Ca Mg desorption or solution Al dominated acid-neutralisation; mobilisation more important later. released 4,542 meq Ca, 1,184 Mg, 2,329 over 45 m long 1 wide segment; smaller amounts Be, Cd, Fe, Mn were released....

Abstract The most frequently used instrument for measuring velocity distribution in the cross-section of small rivers is propeller-type current meter. Output using this point data a tiny bulk. Spatial interpolation measured should produce dense profile, which not available from itself. This paper describes preparation models. Measuring campaign was realized to obtain operational data. It took place on real streams with different distributions. Seven sets were obtained four cross-sections...

The article deals with the current situation of histogram use. overwhelming majority ELINT systems apply depiction in their analytic displays. A significant distinguished radar signals experts use this advantageous function. This contribution shows a breakthrough approach description via Gaussian Specific sections are aimed at creation data library. is followed by experimental demonstration real sample histograms and identification process, which implemented mathematical model process.

This article describes the current situation in area of electronic warfare. Aircraft protection can be greatly utilized not only military but also civilian applications. Active radar signal jamming methods are costly and therefore, aircraft using Chaff increases efficiency, reduces cost. However Chaff, use is restricted or if banned many countries due to its environmental risks. shows how computer simulations for dispersion spreading estimation. These important efficiency analysis...

In given locality, there are low fertility sandy-loamy cambisoils, long-term average annual rainfall 653 mm, temperature 7°C, altitude 620 m. trials were introduced different organic fertilizations and graduate N-doses. According to complex diffusion analysis, statistically significant for yields of winter...

The problem of finding an optimum within a set possibilities that represent the varying successfulness numerous subjects competing with one another is highly relevant in field ecosystem interactions. We propose method for solving this by application Nash equilibrium concept, which frequently used ecology. proposed model based on transformation initial payoff vectors interact different situations into statistical symmetrical game matrices consist permutations values. solution expressed as...

Abstract Restoration of postmining areas is a frequently addressed topic requiring comprehensive view. In this article, the recovery process selected spoil heap sites was evaluated using an approach based on calculation Nash equilibrium (NE) probability distributions. Many these have been allowed to recover by spontaneous succession, while others, variety restoration procedures tested, most them variants forest plantation type. The evaluation carried out data from each site that reflects...
