Habitat edges are regarded as important components of heterogeneous landscapes. Diverse theories exist about the diversity and functional role of edges, and no generalisation have been possible so far, thus case studies are important for better understanding the landscape scale processes. Forest management highly modified the structure and tree species composition of the European forests. The sylvicultural intensification resulted in the rise of the proportion of non-native, intensively managed forest stands. In the present study we explore the response of spider and ant assemblages to forest stand type and the edge effect between native poplar and non-native conifer plantations in Hungary. We applied pitfall traps to sample the ground-dwelling spiders and ants. Four plots consisting of the two forest types and the transition zones between them were selected. Five transects for each replicated plot were sampled. We identified the significant indicator species of the different habitat types. We found significant differences in the species richness (i.e. number of species) of ants and spiders of the different habitat types. We detected intermediate spider species richness at the edge indicating that edges separate a higher quality habitat from one that has lower resource quality; however, the species richness of ants was the highest at the edge and did not differ between the two forest types. The positive impacts of edge was found due to presence of generalist and grassland species at the edge and presumably edges separate patches that provide complementary resources also increasing the number of ant species.Our results indicate that forest type affects the species compositions of ground-dwelling spiders and ants. Our study also shows that habitat type had a major effect on the species richness and composition of spider and ant assemblages, suggesting that local forestry management plays a crucial role in preserving the native invertebrate fauna of forests.

We hypothesized that the flight activity of bats in forests is higher in parts closer to edges due to the presence of species roosting in trees and foraging mostly outside as well as those coming to forage from outside. The aim of our study was to test this expectation using bat netting on roads in a forest belt 4–5 km wide in Kampinos National Park near Warsaw (central Poland). Tree stands were mostly coniferous. Ten full-night study sessions were done between the end of July and the beginning of September in the years 2007–2009. During each session, bats were netted at two sites situated in two zones designated as “edge” (100– 500 m from forest edge) and “interior” (1750–2250 m from forest edge). The study revealed twelve species, among which Eptesicus serotinus (Schreber), Nyctalus noctula (Schreber) and Barbastella barbastellus (Schreber) were by far most abundant. Total bat abundance recorded at ten pairs of netting sites differed significantly between the edge zone (ca. 2.5 times higher numbers) and the interior zone. Among individual species, a statistically important difference was shown only for Plecotus auritus (L.), which was more abundant close to the forest edge, though a similar tendency was noted in other species, mostly E. serotinus. The frequency of each species in the bat assemblage as well as species diversity of bats flying along forest roads did not differ between the two zones.

The presented studies embraced samples of wood chips from coniferous trees which contained layers of duramen, alburnum and bark. Microbiological analysis involved qualitative and quantitative determination of bacterial flora inhabiting the studied wood material. The wood chips were found to contain primarily species belonging to the genera Bacillus and Pseudomonas. The presence of the potentially pathogenic species Bacillus cereus 1, Sphingomonas paucimobilis, Aeromonas salmonicida and Chryseomonas luteola was also demonstrated.

The paper presents the descriptions as well as drawings of three species of eriophyid mites found on coniferous plants as new in Poland: Trisetacus juniperinus (Nalepa) from Juniperus procumbens, Eriophyes junipereti Keifer from Juniperus communis L. ‘Hibernica’ and Cecidophyopsis psilaspis (Nalepa) from Taxus baccata L. Additionally, eriophyoid mites collected from Thuja occidentalis and Tsuga canadensis are discussed in this paper.

Thirty-three type A strains of G. abietina from diseased shoots or needles of P. sylvestris, P. nigra and P. armandii and three strains of Brunchorstia pinea var. cembrae from P. mugo were isolated from four regions of Poland differing with respect to climatic conditions. Genetic polymorphism of the mitochondrial small subunit rRNA (mtSSU rRNA), ribosomal RNA fragment including ITS1, 5.8S and ITS2 and glyceraldehyde phosphate dehydrogenase (GPD) gene was examined by the PCR-RFLP method. Genetic distance was ascertained with respect to B. pinea var. cembrae strains from G. abietina isolated from the examinedpine species (average Nei coefficient 0.137). The smallest genetic distance occurred between the strain groups of G. abietina isolated from P. nigra and P. armandii (0.059) and P. nigra and P. sylvestris (0.061), whereas the highest occurred between the groups of strains deriving from P. armandii and P. sylvestris (0.096). The impact of geographic distance on genetic distance between groups of strains from individual regions has been shown. G. abietina strains originating from mountainous areas were more distanced genetically (on average 0.031) from populations from other regions (Nei genetic distance 0.023). The main factors influencing genetic differences of the pathogen were specificity with respect to the species of the host plant and climate conditions, whereas geographic distance had lesser significance.
