Opis:
With the help of the research results presented here and on the basis of a graphic analysis we aim to prove the existence of a relationship between the difference in prismatic refractive power and the thickness, curvature radius, and type of material used for panoramic oculars in protective spectacles, goggles, and face shields. The difference in the prismatic refractive power is a fundamental optical characteristic of a protective ocular without corrective effect. According to Standard No. EN 165:1995 (European Committee for Standardization, 1995) the difference in the prismatic refractive power is a difference in the prismatic effect at 2 observation points of an eye-protector.

Opis:
In addition to physical defenses, chemical defenses are the most effective way to protect plants from adverse biotic factors (phytophagous insects, other herbivores and pathogenic fungi). This requires extra effort from plants to produce secondary defense metabolites at the expense of production of primary metabolites directly linked to the growth and development of plants. There are three main groups of defensive compounds (alkaloids, phenolic compounds and terpenoids). All defensive compounds are rich in carbon. Depending on the chemical formula, carbon makes up from about 40% to over 85% of the molecular weight of various defense compounds. It is not possible to calculate the total carbon mass accumulation in all defense compounds. In this paper we discuss the content of defensive compounds and carbon with respect to defense strategy of plants, functional groups of woody species (coniferous and deciduous trees), tree species, tree biomass components (leaves, branches, bark, roots, etc.) and many other internal (age of trees, age of leaves, stage of development, origin, etc.) as well as external factors, related to soil and climatic conditions.

Opis:
The potential differentiations in litter chemistry among native and non-native trees are poorly understood. We compared the chemical composition of leaf litterfall of 11 exotic tree species, e.g. coniferous: Abies cephalonica, A. grandis, A. procera, Chamaecyparis pisifera, Pinus peuce, Pseudotsuga menziesii, Thuja plicata, and deciduous: Acer rubrum, A. saccharum, Betula alleghaniensis and Quercus rubra, with that of a native European conifer, Pinus sylvestris (as reference to coniferous species) anda mixture of native European Quercus robur, Carpinus betulus, Tilia cordata, T. platyphyllos and Corylus avellana leaves (as a reference mixture of deciduous species). We found significant differences among the species studied in nitrogen and carbon content in needles/leaves, C/N ratio, as well as total soluble phenolic compounds (TPh) and total nonstructural carbohydrates (TNC) content, including soluble carbohydrates and starch. However, we found no clear differentiation of exotic from native tree species in the analyzed elements and metabolites. Among the exotic coniferous tree species, P. menziesii stood out among the species studied – fallen needles of this species were characterized by relatively high TPh and TNC content. The relationships between TPh and TNC content in leaf and needle litter among tree species were similar among two consecutive years. For deciduous tree species, the tendency of higher TPh content and C/N ratio in leaves falling earlier (September; leaves of sun-type) than later (November; leaves of shade-type) was more distinct than in coniferous tree species. Generally, we cannot see any special differences in the levels or mutual quantitative relationships of the chemical compounds studied in fallen needles/leaves of exotic tree species in comparison with native tree species.

Opis:
Ostrożeń polny (Cirsium arvense (L.) Scop.) jest uciążliwym chwastem upraw roślin w gospodarstwach ekologicznych i konwencjonalnych w Polsce, który może być zwalczany z wykorzystaniem grzybów patogenicznych. Zastosowanie patogenów ostrożenia polnego wprawdzie budzi poważne wątpliwości epidemiologiczne, wynikające z możliwości zakażenia roślin uprawnych, jest jednak możliwe. Wykorzystanie bioherbicydów na pastwiskach i łąkach jest docelowo jednym z najodpowiedniejszym sposobów bezpośredniego zwalczania ostrożenia polnego i innych chwastów. Zastosowanie P. punctiformis na gruntach ornych nie budzi wątpliwości epidemiologicznych, jednak, ze względu na konieczność manualnej aplikacji patogena, jego wykorzystanie będzie najodpowiedniejsze w uprawach prowadzonych w gospodarstwach ekologicznych. Inne grzyby, odpowiednio dobrane do upraw roślin, tak, aby nie stwarzać zagrożenia epidemiologicznego, mogą być podstawowym czynnikiem zwalczania ostrożenia polnego lub wspomagać zwalczanie tego chwastu prowadzone z użyciem tradycyjnych herbicydów.
Creeping thistle is a burdensome weed of crop plants in ecological and conventional farms, which can be controlled using pathogenic fungi. Although using pathogens of creeping thistle can stir up important doubts from epidemiological point of view, resulting from an opportunity to inoculation of crop plants, it can be possible. Application of bioherbicides on pastures and meadows is ultimately one of the most suitable method of direct control of creeping thistle and other weeds. A use of P. punctiformis on arable land can not raise doubts, however, due to necessity of manual application this method, should be the best in ecological farms. Other fungi appropriately selected to a crop can be a basic method of creeping thistle control or assist a control of it weed with traditional herbicides.

Opis:
Experimental data on carbon concentration in woody plant species biomass are very scarce and value of 50% of dry biomass is widely accepted in carbon storage modeling. On the other hand, some studies have proved that the carbon concentration in woody species biomass is variable and depends on the component. Thus, the main goal of the study was to determine carbon concentration in biomass of 7 understory shrub species (basing on 282 individuals): Corylus avellana, Prunus padus, P. serotina, Frangula alnus, Sambucus nigra, Cornus sanguinea and Sorbus aucuparia as well as to analyze variability of carbon concentration among shrub species and biomass components. Carbon concentration was analyzed for leaves, fruits, branches, stemwood, stembark, coarse and fine roots. Our study revealed that the mean carbon concentration in biomass of all species studied was 47.7%. We found statistically significant differences in carbon concentration among the shrub species studied in all biomass components. The mean value for particular species was as follows: Prunus serotina – 47.5%, P. padus – 47.6%, Frangula alnus – 47.7%, Sambucus nigra – 47.7%, Corylus avellana – 47.8%, Cornus sanguinea – 47.8% and Sorbus aucuparia – 47.8%. Additionally, we found statistically significant differences in carbon concentration among biomass components within the species studied. The mean carbon concentration in fruit biomass was 46.2%, in fine roots – 47.0%, in leaves – 47.2%, in coarse roots – 47.7%, in branches – 47.9%, in stemwood – 48.5% and in stembark – 48.6%. The variability of carbon concentration in fruit, branches and leaves biomass was higher than in the remaining biomass components. The variability of carbon concentration in biomass of woody species should be considered in carbon storage modeling in forest ecosystems.

Opis:
Future climatic warming may modifyinsect development, sex ratio, quantitative changes in populations that could affect the frequency of outbreaks. Here we analyzed the influence of temperature on larval growth and development in the gypsy moth (Lymantria dispar L.). The larvae were reared at three constant temperatures: 15, 20 or 25°C, and fed with leaves of the English oak (Quercus robur L.). Larval mortality, duration of development (DD), relative growth rate (RGR), total mass of food eaten (TFE), and pupal mass (PM) were estimated. Larval mortality was lowest at 20°C, higher at 25°C, and highest at 15°C. DD significantly decreased with increasing temperature and depended on sex. The influence of temperature on the shortening of DD was stronger in males than in females. RGR significantly depended on temperature and was the highest at 25°C, and lowest at 15°C. At 15°C, RGR did not change markedly with time. In contrast, RGR at 20°C was characterized bya continuous decreasing trend. At 25°C, RGR was very high for 2 weeks but quickly declined afterwards. Temperature did not affect the TFE. PM was significantly correlated with temperature and sex. PM of females was higher at 20°C than at 15 and 25°C, in contrast to that of males, which was similar at 20 and 25°C, and higher than at 15°C. For larval growth and development, the most favourable was the medium temperature (20°C). The least favourable temperature for females was 25°C, for males 15°C. The results suggest that global warming may modifythe future sex ratio of gypsy moths that may affect insect development and outbreaks.

Opis:
Effect of a weak defoliation by the larvae of the lappet moth and nun moth on chemical composition of needles, litter and soil in the 33−years old Scots pine stands was studied. The four variants were tested: I – larvae feeding, litterfall with frass and damaged needles, II – larvae feeding, but litterfall excluded (collected), III – no larvae, litterfall from the variant II spilled around trees, IV (untreated) – no larvae, litterfall without frass and damaged needles. No changes in chemical composition of litter and soil after two years of weak spring defoliation were found. However, there was a significant decrease of soluble carbohydrates and 5 sesquiterpenes as well as an increase of total monoterpenes in needles of trees in the variant II in comparison to other variants. All of those compounds are carbon−based, thus trees probably only relocated this element to a higher production of monoterpenes to make needles less attractive as a food source.

Opis:
The quality of leaves as food for insects is affected both by plant species and the light conditions present during growth. Little information exists concerning the impact of these factors on the diversity of insects that live in the forest understory. We studied arthropod fauna on six understory plant species commonly occurring in Europe. Different groups of herbivorous insects were identified, as well as predatory insects and arachnids. We analysed the influence of both plant species and light conditions during growth (low light; high light) on the species spectrum, and the number of insect specimens present. The resulting data were investigated in relation to the susceptibility of plant leaves to feeding by folivorous insects, as determined in earlier studies. We compared the similarity in species diversity, based on the Sørensen’s coefficient, and discussed the potential causes of observed differences in leaf damages. We found a total of 153 arthropod taxa on studied plants, under both light conditions. Corylus avellana and Prunus serotina, species characterized by greater leaf damage, have a wider diversity of arthropod species, and a greater number of herbivorous insects. Generally, light conditions had a greater effect on arthropod abundance than on species diversity. For two plant species, C. avellana and P. serotina, light conditions strongly, but reversely, influenced the total number of insects and, thus, the extent of leaf damage. The number and abundance of zoophagous species, and ratio to folivores (except C. avellana) are associated more with plant species than with light conditions
