Opis:
The study focuses on the variation of the adaptation features of forty partial populations of beech from the area managed by the Katowice Regional Forest Directorate. The growth and development of the provenances were assessed in the years 1998−2003 by measuring the height and survival of seedlings in the juvenile phase, i.e. up to the fourth year of planting on comparative plantations of the Regional Gene Bank that were established at two different forest sites of the area. The selection indices of the provenances were calculated from the variation components.

Opis:
The paper presents the results of the assessment of the genotype−soil interaction effect on adaptive traits in beech provenances in gene conservation areas of the Regional Bank of Genes (RBG) in the territory administered by the Katowice Regional Directorate of the State Forests. The level of Ca concentrations had no significant effect on survival and growth of beech in the juvenile phase. The interaction effect significantly increased with tree age, while the genotypic effect was less significant. The research confirmed the ecotypic nature of genetic variation in beech.

Opis:
Paper presents analysis of differences in conventional wood density of Scots pine measured at breast height regarding the geographical location of stands, forest habitat type, stand age and associated parameters such as density in the mid−length of the stem, density in the upper end of the stem and diameter at breast height. To investigate the impact of these factors, an analysis of covariance was used in accordance with two models specifically developed for this purpose. We found dependence of conventional wood density on the type of forest habitat and geographical location of the stand. The highest density was detected in dry coniferous forests, while the smallest in fresh mixed coniferous forests. Scots pine wood from Zielona Góra Forest (western Poland) characterised with the highest density, while from the Knyszyn Primeval Forest (eastern Poland)− with the lowest.

Opis:
The aim of the studies was to check the usefulness of ITS1/2 rDNA and 18S rDNA regions in the molecular investigation of forest soil microbiota structure. Soil studied, originated from a 1−year−old plantation and a 40−year old stand of Scots pine located in Bierzwnik and Międzychów forest districts located 200 km apart. The hypothesis assumed that both approaches lead to the discovery of abundant microbiota communities with different structures and with rare common species. The environmental DNA was extracted with a Power Soil ® DNA Isolation Kit from two soil samples in each site. The ITS1/2 rDNA was amplified with specific primers ITS1 and ewfitsrev 1, and 18S rDNA with universal primers NS1 and NS2. PCR products were cloned into pGEM−T Easy. Inserts were primarily selected in blue/white screening on a X−gal medium. Representative clones were further selected in two separate RFLP analyses with HhaI and BsuRI restriction enzymes. Representative clones purified and sequenced using the Sanger Method in the DNA Research Centre (Poznań). Each sequence was identified to the lowest taxonomic rank. Ninety to 233 clones with DNA of 5−44 taxa including 3−37 taxa of fungi were obtained from 4 samples of soil. After application of ITS1/2 rDNA and 18S rDNA, the fungal DNA was detected respectively in 89,60−100,00% and 11,77−64,8% clones and the number of fungal species detected was respectively 12−37 and 3−19. Fungi were represented by four orders: Chytridiomycota, Zygomycota, Ascomycota and Basidiomycota. Both primers also amplified also DNA of other organisms (mostly from Animalia and Protista Kingdom) represented by 0−9 taxa. If compared, the application of forest soil microbiota structure with ITS1/2 rDNA and 18S rDNA led to detect a lower abundance of fungi and a bigger abundance of other organisms. Considering the higher number of clones and taxa recognized, the region of ITS1/2 rDNA was more effective in the studies of the soil microbiota structure. The region of 18S rDNA was efficient in local detection of Chytridiomycota and Zygomycota and of rare species of fungi from Ascomycota and Basidiomycota. Despite the deficiency of NCBI database the use of the 18S rDNA region in studies on fungal community the region should be included in molecular studies of fungal diversity. It is concluded that studies on the biodiversity of soil microorganisms need the application of a few independent methods of detection and identification.

Opis:
Two different communities of microorganisms were identified in soils by application of the classical method of fungi isolation (soil dilution, culturing on artificial media, morphotyping) and a molecular method (extraction of the environmental DNA, amplification with universal primers NS1 and NS2, cloning and sequencing of representative clones). No organisms were common to both communities. Apart from rare representatives of the Animalia, communities included single fungus−like Eucarya belonging to the Protista, Class Oomycota, and numerous fungi belonging to Chytridiomycota, Zygomycota, Ascomycota and Basidiomycota orders. In total, 88 species were identified in four soil samples. Fungi were mostly Ascomycota. The classical method was particularly effective in detection of fungi important for creation of phytosanitary conditions of soil, i.e. antagonists (Penicillium, Tolypocladium and Trichoderma) and potential stimulants (dark−pigmented Hormiactis candida, Humicola spp. and Phialophora spp.) of phytopathogens (including the common forest genera Armillaria and Heterobasidion). Application of the classical method allowed the detection of mycorrhizal Ascomycota from the genus Oidiodendron. Application of the molecular method allowed the detection of 13 mycorrhizal Basidiomycota. Although primers NS1 and NS2 were designed from a match with DNA of culturable organisms, they also amplified the DNA of non−culturable organisms. This emphasizes their potential usefulness in studies of the biodiversity of microorganisms in environmental samples. The shortage of reference sequences in the database discourages use of the 18S rDNA region in studies on fungal communities. The studies on the biodiversity of microorganisms need the application of a few independent methods of detection and identification.

Opis:
The efficiency in Trees protection against European beaver (Castor fiber) of two different repellents: JTEATON and REPENTOL 6 BIS PA was studied under laboratory condition. Both types of repellents showed no efficiency in willow branch protection against beaver browsing. Willow branches protected by two repellents were damaged in the same level as non−protected branches (control) both under low (1 beaver) and high predation risk (2−4 beavers). Data from this experiment suggest that tested repellents were not efficient in trees protection against beaver.

Opis:
Phytophthora and Pythium species (Oomycota) are known to be serious pathogens of forest trees. Little is known, however, about their presence in Polish oak forests and their role in the oak decline, especially in the flooded areas. The aim of this study was (1) to detect and compare populations of microorganisms from Oomycota and fungi in roots and soil of healthy and declining pedunculate 30−126 years old oak stands, which had been flooded by the Odra River for three months in 1997 and one month in 2010, (2) to demonstrate the relationship between different chemical factors of soil and the occurrence of microorganisms, and (3) to assess the contribution of Oomycota to oak decline. Study was carried out in Wołów Forest District (south−western Poland). Microorganisms were isolated from fine (1−5 mm in diameter) roots and non−rhizosphere soil collected from 0−50 cm horizon. Isolation procedure from roots included surface sterilization and plating the root segments on the nutrient agar. An oak leaf baiting method was used for isolation of Oomycota from soil. Identification of microorganisms was based on morphology and sequencing of the ITS1/2 rDNA. Oomycota was represented by: Globisporangium, Phytophthora and Pythium and fungi mostly by: Aspergillus, Chaetosphaeria, Cylindrocarpon, Mortierella, Mucor, Penicillium, Trichoderma and Umbelopsis. Globisporangium attrantheridium (syn. Pythium attrantheridium) occurred locally and was found in roots of only one flooded oak. This is the first record of this species on oak and in Poland. G. intermedium, P. gibbosa/P. gregata, P. plurivora and Pythium sp. were found in soil of flooded and non−flooded (control) oak stands. The organisms occurred in podzolized brown soils, brown alluvial soils and gley soils that had most nitrogen (21−60 mg/kg), various amounts of calcium (61.1−347.6 mg/100g) and moderate acidity (pH=3.85−4.2). There was often a significant association between exposure to flood and the health status of oak trees assessed by the scale of defoliation. Oomycota seemed to be only moderately associated with increased tree defoliation as a symptom of oak decline.

Opis:
The presence of microorganisms in the substrate is detected with increasing frequency using chemical methods. During the first 9 weeks ergosterol concentration in sterile or not sterile soil inoculated with one of the damping−off fungi reached 966 μg/g, while number of colony forming units (cfu) went up to 247×103 cfu/g. Ergosterol concentration was correlated with the size of the soil fungal community estimated in terms of the number of colony forming units in soil. Pearson's correlation coefficient was 0.700−0.946 for sterile and not sterile soil. Higher content of ergosterol was observed for F. sambucinum var. sambucinum, H. haematococca and T. cucumeris while higher average content of cfu was observed for H. haematococca and T. cucumeris.

Opis:
The paper presents a multifaceted structure of timber harvest in 2008−2015 in the Białowieża, Browsk and Hajnówka forest districts located in the Białowieża Forest. The object of the research, including the Białowieża National Park being a remnant of the primeval forests, is considered one of the most valuable forest areas of natural origin in Europe. The studies were made on the basis of the data from the reports created by the State Forests Information System and forest management plans, as well as the nature conservation programs of the surveyed forest districts. In the analysed period, a total of 665,032.5 m3 of merchantable timber was harvested in the analysed area. The highest volume of merchantable timber was harvested in the Browsk Forest District – 305,934 m3 (46%), then in the Hajnówka Forest District – 219,300 m3 (33%), with the lowest volume harvested in the Białowieża Forest District 139,788 m3 (21%). Among the individual assortment groups, the medium−sized timber was the most common and its harvested volume amounted to 413,579 m3, while the harvested volume of large−sized timber amounted to 251,454 m3. The lowest harvested volume concerned the small−sized timber and amounted to 21,652 m3. In the analysed period, softwood had the largest share in timber harvest and amounted to 443,469 m3. Hardwood was obtained in the volume of 243,215 m3. According to the cutting category, the timber harvest structure was as follows: the highest volume was harvested in pre− commercial thinning 382,495 m3 (54%), that from incidental felling amounted to 251,003 m3 (38%), while the lowest volume of harvested timber was from final cutting – 53,186 m3 (8%). Forest districts located in the Białowieża Forest encounter many difficulties affecting timber harvest. The main reason for this lies in the numerous restrictions imposed on the management of areas covered by various forms of nature protection, including the exclusion of some habitats, or stands of 100 years of age and older from management, which significantly affects the yield. The lack of a determined rotation age for stands in the Białowieża Forest also has a significant impact on timber harvest.
