Opis:
Results of the investigations of spatial and temporal differentiations of Apoidea in the forests of Wielkopolski National Park were presented. It was shown that the both forest floor differ with the degree of species differentiation and domination’s structure and total number of bees. In the herbaceous layer of the forests about twice as many spedes were found than in the crowns. Also the Shannon-Weaver’s indices for bees communities of the herbs layer are higher in all three investigated forest ecosystems. The curves of Apoidea numbers in tree crowns and forest floor were similar. The curves of Apoidea numbers in the deciduous forests have one peak in the first days of May. Whereas the curves of Apoidea numbers in the pine forest have multi peak course. It was proved that trees play an important role in feeding chain of bees inhabiting deciduous forests.

Pine wilt disease caused by pine wood nematodes is endemic to North America. Pine wood nematodes have already spread to East Asia, including China, Taiwan and Korea in addition to Japan. The pine wood nematode, Bursaphelenchus xylophilus, was discovered in Portuguese pine forests in 1999. If it were to become established in the pine forests in Europe, it could become one of the most serious threat to coniferous forests worldwide.

Opis:
The Tomczyce nature reserve is characterized by a degenerated forest vegetation. We assume that the regeneration process was possible to launch after the establishment of the nature reserve in 1968. The vegetation of the Tomczyce forest complex was characterized for the first time by Jakubowska-Gabara (1976) whose studies were taken as a basis of our research. The phytocenoses after 40. years of protection have a greater participation of species with higher trophic and moisture requirements. The regeneration process in communities with pine trees is caused by an expansion of broad-leaved trees and shrubs. Transformation of forest vegetation causes a decrease in cover of thermophilous and heliophilous species. On the other hand, species of oak-hornbeam forests as well as anthropophytes are in expansion. Planning of the protection activities in the nature reserve needs to include these dynamic tendencies of the vegetation.

Opis:
The diversity of ectomycorrhizal fungi and sporocarps abundance were investigated in 2003-2005 at nine permanent study plots in a 50-year-old pine forest. Diversity of ectomycorrhizal fungi consist of 53 taxa and the majority of them belonged to the genera Cortinarius, Russula, Amanita and Tricholoma. The most frequent species, whose fruit bodies were found in each study plot, were C. cibarius, L. necator L. rufus, P. involutus, R. aeruginea, T. saponaceumand the most abundant species which made the main part of total sporocarp yield were C. cibarius and P. involutus. The lowest species richness of ectomycorrhizal fungi was in study plots with the densest cover of grasses. Maximum of species over the fruiting period was characteristic for October and for September. It was noticed that some species virtually never occurred together at the same plot (e.g. C. cibarius and H. aurantiaca), meanwhile others occurred together quite frequently (e.g. H. aurantiacaand X. badius).

Opis:
A Scots pine forest, affected by the great cormorant colony, was studied by plot-based fungal survey method during the years 2010-2012 in Lithuania. Diversity and composition of fungal communities were investigated at five zones that had been influenced by different stages of breeding colony establishment: starting-point and almost abandoned cormorant colony part (zones A and B), active part (zones C and D), and the edge of the colony (zone E). The control zone G in undamaged by cormorants pine stand was assessed too. A total of 257 fungal species of ascomycetes including anamorphic fungi, basidiomycetes and zygomycetes were recorded. Seven species were registered for the first time in Lithuania. Species richness in the examined zones varied, lowest being in zones B (51 species), C (46) and D (73) and almost twice as high in the zones A and E (129 and 120, respectively). The comparison of fungal species compositions of different zones showed that their similarity was rather low (SS: 0.22–0.59). The most obvious changes in the trophic structure of fungal communities in the territory occupied by the bird colony were a strong decrease of mycorrhizal species, the presence of coprophilous fungi on forest litter, and the appearance of host-specialized fungi on alien and non-forest plants that have established in the disturbed forest.

Opis:
The aim of the research described in this paper is to classify groundwater level patterns in pine stands of forest fresh sites. The approach has been employed with the view to facilitate explaining interactions between physiographic characteristics and groundwater dynamics in prospective research. The methods which have been employed so far for explanation of groundwater level dynamics interactions with local physiographic conditions do not let to draw firm conclusions. The classification of groundwater dynamics patterns requires employing more sophisticated methods, because of a relatively extensive range of groundwater dynamics site-to-site variability expressed, e.g., by amplitude and cycle period. The methods of groundwater patterns classification proposed in the literature focused either on hydrogeological criteria or, if related to forest ecosystems, focused on water balance elements in forest habitats. The area selected for investigation represented typical features for the Northern European Lowland forests defined by soil and form of terrain pattern shaped by the last glacial period (Vistulian glaciation) and dominant share of Scots Pine (Pinus sylvestris L.) in stand species composition. The research period covered the 2002-2007 hydrological years. The measurement used in analysis covered 35 sites equipped with measurement wells.

Opis:
In agricultural area of Konin where previously no industrial activity was performed the complex of power stations combusting brown coal was built in the end of the fifties followed by the aluminium smelter which was put into operation in 1965. Both these industrial works emit considerable amounts of phytotoxic gases (F2, SO2, NO2). Aluminium smelter emits vast amount of fluorine as aluminum is produced by thermoelectrolysis of aluminum oxide in electrolyte consisting of cryolite and aluminum fluoride as well as it is a major emitter of PAHs due to carbon electrode "combustion". Because these plants did not meet technology parameters and production was poorly controlled in first period of activity harmful effects of their emission in the natural environment were observed. Beginning from the nineties intensive proecological efforts were made and intensive modernization of the plants was performed. All these activities resulted in a significant reduction of air pollutants emission. The paper presents the results of investigation carried out in the monitoring net established in Konin area. The fate of air pollutants currently emitted and deposited to the soil within a long period of the plants activity was determined. The vacuum ceramic cup lysimeters were used to assess the concentration and hazard of inorganic and organic chemicals for water - soil environment. On the basis of differences in concentration of cations and anions the rate of nitrification and acidification processes in the soil was also analysed.
W otoczeniu Konina na obszarze typowo rolniczym, gdzie uprzednio nie prowadzono działalności przemysłowej, na początku lat pięćdziesiątych, wykorzystując węgiel brunatny z kopalni odkrywkowych uruchomiono kompleks elektrowni PAK (Pątnów, Adamów, Konin), a w roku 1966 oddano do eksploatacji Hutę Aluminium "Konin". Zakłady te emitowały znaczne ilości gazów fitotoksycznych (F2, SO2, NO2). Huta aluminium emituje duże ilości fluoru, ponieważ aluminium produkowane jest w procesie termoelektrolizy tlenku glinu w elektrolicie zawierającym kriolit i fluorek glinu, jak również jest znaczącym emiterem WWA (PAHs) powstających w wyniku "spalania" elektrod węglowych. Ze względu na to, że zakłady przemysłowe w początku swej działalności nie spełniały wymaganych parametrów technologicznych, a emisje do atmosfery gazów odlotowych były niewystarczająco kontrolowane w środowisku przyrodniczym występowały wyraźnie szkodliwe efekty. W latach dziewięćdziesiątych podjęto intensywne działania proekologiczne i modernizacyjne zakładów, które doprowadziły do znacznej redukcji emisji zanieczyszczeń powietrza. W pracy przedstawiono wyniki badań przeprowadzonych w lasach sosnowych znajdujących się w sieci monitoringowej ustanowionej na obszarze Konina. Przedstawiono poziom depozycji zanieczyszczeń do ekosystemów leśnych oraz migrację aktualnie emitowanych zanieczyszczeń i zdeponowanych w glebie w okresie długoletniej działalności zakładów. Do oceny stężeń i zagrożenia środowiska wodno-glebowego związkami organicznymi i nieorganicznymi zastosowane ceramiczne lizymetry próżniowe. Na podstawie różnic w stężeniach kationów i anionów w różnych przedziałach ekosystemu leśnego określono także natężenie procesów nitryfikacyjnych w glebie.

Opis:
At present, forest fire research is becoming especially relevant in Ukraine. This study examines patterns of forest fuel accumulation in pine (Pinus sylvestris L.) stands that grow in different soil conditions with different pine stand structure. To estimate the load of forest fuel of different fractions, a combined methodology was used: the weighing method and the FIREMON (fuel load estimation) method. It was found that increase in surface forest fuel loads is not directly proportional to forest stands’ age. Fractional size distribution, capacity and loads of forest fuel depend on several factors, among which the greatest role is played by forestry characteristics of the pine stand. It was determined that in the forest site conditions of type C (fairly rich soils) in Kyiv Polissya, the share of forest litter compared to pine stands that grow in poor soil conditions (A) is smaller, ranging from 41% to 76% of the total forest fuel load. The mass proportion of the duff layer varies from 15% in young forest stands to 43% in mature stands. It was established that changes in forest fuel fractions for 1, 10, 100 and 1000 hours varied insignificantly with age rate. The share of substratum woody debris of 10 and 100 hours was insignificant and depended more on the forestry treatment regime on these sites. The mass proportion of coarse woody debris (1000 hours) was also insignificant, varying from 0% to 5.9% of the total load of surface fuel.

This paper presents the edge effect of a very low-volume road on the belt of roadside vegetation in the “Puszcza Notecka”, Poland - one of the largest compact forest complexes in Europe. The observations were carried out in the vicinity of pine stands in the fresh coniferous forest and fresh mixed coniferous forest sites. Twelve rectangular experimental sites 30 and 50 meters wide at a distance of 0 to 10 meters from the edge surfaces were established. 75 species characteristic for the 13 phytosociological classes and 20 species associated devoided of the diagnostic value were recognized in the roadside area. Native species dominated, where the most numerous species belonged to meadow communities (Molinio-Arrhenatheretea) and ruderal (Artemisietea vulgaris). Despite the significant participation of synanthropic plants, there was no invasion of alien species.

Opis:
Effects of Scots pine wood amendment on the fungal community in forest soil infested with cockchafers and foraged or non-foraged by wild boars and hares were investigated. We hypothesized that sawdust amendment would increase the abundance of entomopathogenic and insect-associated species effective in cockchafer predation. The soil dilution method and morphotyping were used for fungal isolation and identification in order to quantify and qualify the viable components of the microbiota that are important for evaluating soil functions. There was usually increased abundance and decreased diversity of soil fungi one year after sawdust amendment. Application of pine sawdust more often increased than decreased the abundance of some insect-associated fungi or dermatophytes and keratinophilic species and decreased the number of cockchafer larvae. Abundance of Geomyces pannorum, Mortierella spp. + M. luteus, Pseudogymnoascus roseus, Tolypocladium inflatum and Trichoderma koningii increased, at least locally, whilst Chrysosporium merdarium, Penicillium spp. (including the most common P. citrinum, P. daleae and P. janczewskii), Sporothrix schenckii and Trichoderma spp. decreased. Application of pine sawdust under roots of 1-year-old Scots pine seedlings significantly increased the abundance of Phoma + Pyrenochaeta spp. in neighbouring soil, thus increasing the risk from Phoma blight. Trichoderma strigosum was among the dominants (frequency >5%). Another six and two Trichoderma species were among the subdominants (frequency 1–5%) and subrecedents (frequency <1%), respectively. Dermatophytes, coprophilous and keratinophilic species, e.g. Cephalotrichum, Chrysosporium merdarium or S. schenckii, occurred only or mostly in foraged plots. The altered communities resulting from pine sawdust amendment may contribute to biological control of the cockchafer larvae.

The illumination under the canopy in different types of pine and spruce forests is considered. The research was carried out in different points of the Northern taiga of the Arkhangelsk region. Illumination was measured using a luxmeter in different directions: at the level of the moss-lichen layer, at the level of the grass-shrub layer and at a height of 1.3 m; at different distances from the tree trunk; at different distances from the edge of the forest. Illumination in pine forests at the level of the moss-lichen layer is 2.3 times higher than in spruce forests. Under the canopy of spruce forests, it is 1–3%, and in the pine forests, 3–9% of the illumination in the open. Illumination from tree trunks to the edge increases in pine and spruce forests equally. The lowest illumination is observed at the level of the moss-lichen layer, then it increases to the grass-shrub layer, and then practically does not change. However, the difference between pine and spruce forests is consistently high 47%. The decrease in illumination in the tree stand as it moves away from the edge in blueberry pine forests is observed up to a distance of 10 m from the edge, and in blueberry spruce forests up to 6 m.
