    Opis:
    Two field inoculation experiments were conducted to study intraspecific variation in vertical spread of the P-, S- andF-IS-group isolates of Heterobasidion annosum in stems of Pinus sylvestris, Picea abies and Abies alba. Host-plants were inoculated with four isolates of each IS group after 10 mm long wounds made with a sterile knife (experiment 1) or 3 mm diameter radial holes made with a drill (experiment 2). On pine, the P-group isolates were more virulent than S andF isolates in terms of infection frequency, mortality rate andvertical spread in sapwood. The S isolates had higher incidence of infection and extensive growth on spruce than on pine. The F isolates were significantly less virulent on pine andspruce than on fir. Vertical spreadof all IS groups on fir was similar. In spite of between-strain-within-IS group variation in vertical spreadon each host, the study provided strong evidence for the occurrence of intraspecific differences in the host preference. In the interspecific analysis with three hosts, the isolates, IS groups andhost × strain andhost × IS group interactions accountedfor most of the explainedvariation, while host-plants accountedfor the smallest portion of the variance.

    Opis:
    Background. Although the parasitofauna of wild carnivorous mammals in Poland is quite well recognized, there has been only one research carried on this issue so far in Białowieża Forest - the last lowland primeval forest of temperate zone in Europe. Material and methods. Twelve wild and two domestic species of carnivorous mammals are living in Białowieża Forest. In our work faeces or intestines of all of them except ermine (Mustela erminea) have been examined and parasites or their eggs (or oocysts) recorded. In total 222 faecal probes from 13 species and 11 intestines of weasels have been investigated. Results. All species of examined carnivorous mammals were infected with parasites. The most infected species has occurred red fox Vulpes vulpes (over 70% infected with parasites) meanwhile only about 30% of otters Lutra lutra were infected. We found at least three protozoan species, one trematode, one tapeworm and nine species of nematodes. Except trematode Alaria alata, all of them are reported for the first time from Białowieża Primeval Forest. Oocysts of coccidia have been found in faeces of nine host species, with the highest prevalence (29.4%) in badger. Six species of carnivorous mammals have been occurred infected with trematodes (highest prevalence 42.1% in wolves) and two with tapeworms (Diphyllobothrium latum with the prevalence 2.6% in otter and 31.6% in wolves). All examined host species were infected with nematodes (with prevalence from 14.7% in lynx to 72.7% in red fox). Results of our work should be treated as preliminary researches on the species composition of parasitic fauna invading carnivorous mammals in Białowieża Primeval Forest.

    Tolerance of several strains of the P-, S-, and F- intersterility groups of Heterobasidion annosum to low pH and high concentration of aluminium ions was studied on malt extract agar. There were marked intraspecific, but not intergroup, variations in tolerance to both factors. Some strains were relatively tolerant or sensitive to low pH and aluminium, while the others were tolerant to low pH but sensitive to Al. There was no relationship between tolerance of the strains to low pH and their tolerance to aluminium stress.

    Opis:
    Investigations of genetic diversity of Heterobasidion spp. in Scots pine, norway spruce and european silver fir stands indicated that almost all of identified genets occurred in those stands were small occupied only a single stump. in some cases two, three or even four genets could effectively exist in an individual stump. genetic similarity of H. annosum s.s. genets varied from 0% to 62%, H. parviporum from 0% to 38% and H. abietinum from 0% to 55%. the oldest and biggest genet was found in laying fir log and overgrew the wood for at least 14 years. this genet belonged to H. abietinum. the size of genets was related to thinning operation, spore dispersal, age of stand or competition in wood colonization.
    Badania nad zróżnicowaniem genetycznym gatunków rodzaju Heterobasidion w drzewostanach sosnowym, świerkowym i jodłowym wskazały, że niemalże wszystkie genotypy wystę-pujące w badanych drzewostanach były małe i zasiedlały co najwyżej jeden pniak. wkilku przypadkach stwierdzono występowanie dwóch, trzech, a nawet czterech genotypów w jednym pniaku. Podobieństwo genetyczne genotypów H. annosum s. s. wynosiło od 0% do 62%, H. parviporum od 0% do 38%, a H. abietinum od 0% do 55%. najstarszy i największy genotyp stwierdzono w leżącej kłodzie jodłowej, której drewno przerastał, przez co najmniej 14 lat. ten genotyp należał do H. abietinum. rozmiar genotypów był związany z intensywnością cięć pielęgnacyjnych w drzewostanach, rozprzestrzenianiem zarodników, wiekiem drzewostanów oraz konkurencją w zasiedlaniu drewna pomiędzy genotypami.

    Opis:
    The abundance and diversity of wood decomposing fungi were investigated by isolating and cultivating filamentous fungi from wood and by detection of fruit bodies of ascomycetous and basidiomycetous fungi. The objective was to study the impact of forest management on fungi in 100-year-old oak and 87-year-old Scots pine forests in Northern Poland. Fungi were found on coarse woody debris of decayed stumps and fallen logs, boughs and branches in each of the three (managed and unmanaged) examined stands. In total, 226 species of Oomycota and fungi were recorded. Oak wood was colonized by one species of Oomycota and 141 species of fungi including Zygomycota (19 species), Ascomycota (103 species) and Basidiomycota (19 species). Scots pine wood was also colonized by one species of Oomycota and 138 species of fungi including Zygomycota (19 species), Ascomycota (90 species) and Basidiomycota (29 species). In the first, second and third stages of decomposition, the oak wood was colonized by 101, 89 and 56 species of fungi respectively and pine wood was colonized by 82, 103 and 47 species respectively. Eighty three of the observed species (37%) occurred on both types of wood, while the other species displayed nutritional preferences. A decrease in the number of species with advancing decay indicates the necessity for a continuous supply of dead wood to the forest ecosystem. This supply would secure the continuity of fauna and flora and guarantee a stable forest development. The nutritional and ecological preferences of many fungal species furthermore indicate the necessity of supplying the forests with wood of different species. In commercially managed forests the results obtained here will aid in: (i) the development of strategies for effective dead wood management in the context of forest productivity and future wood stock growth, as well as (ii) finding a compromise between forest management requirements and environmental protection.

    Opis:
    Prepenetration and penetration phenomena after inoculation of roots of Pinus sylvestris seedlings grown in vitro with the P-, S- and F-group isolates of Heterobasidion annosum were observed using scanning electron microscop. There were no differences in the behaviour of hyphae and in the appearence of mycelia formed by the three IS-group isolates. Four types of the root penetration by hyphae were observed. In the first, the entrace of hypha into root was achieved throught tiny pore formed in walls of the cortical cells. In the second, swellings resembling appressoria were formed by the hyphal tips at the points of contact with the root surface. In the third, the hyphae penetrated cells through holes in eroded areas of roots, and in the fourth by the natural crevices at points of the cortical cell junctions. It is concluded that the different frequencies of the four types of penetration observed after inoculation with isolates of the three IS group should be carefully explained in term of their different pathogenic and saprobic capabilities on pine.

    Opis:
    The growth of hyphae and prepenetration phenomena on Abies alba roots after inoculation with the P-, S- and F-group isolates of Heterobasidion annosum were observed using scanning electron microscope. Elongated hyphae emanating from the inocula grew indiscriminately across and along root tips and entered the cortical cells randomly, while in subapical root areas they quite often grew along grooves at points of cell junctions. The ridges, folds and depressions seen on the root surface obviously directed the hyphal growth and their further entrance into roots through natural crevices or cracks. Although hyphae of all the isolates could penetrate the roots directly through small openings, the hyphae of the F isolate penetrated preferably more eroded and older parts of roots. A peculiar habit of the direct penetration, characterized by formation a structure resembling infection peg, was observed only after inoculation with the P and S isolates. It is suggested that specifically frequent penetration the roots in eroded areas by the hyphae of the F isolate may be one of the factors connecting with its lower pathogenic capabilities.

    Opis:
    Three elm species are native to Poland: wych elm (Scots elm) (Ulmus glabra Huds.), field elm (U. minor Mill.), and European white elm (fluttering elm) (U. laevis Pall.). The epidemic of Dutch elm disease (DED) has led to a decrease in the popularity of elm cultivation. An analysis of forestry data was the first step in the assessment of elm resources. The area of forest stands where elms are dominant has more than doubled since 1978. Lowland alluvial forests rank first in regards to the number of elm localities per unit area of a given forest site type. While this site type is clearly preferred by elms, the majority of elm trees are actually scattered among sites of oak-hornbeam or closely related forests (of the alliance Carpinion betuli). Field research revealed a clear dominance of U. laevis, a species which in the past was predominantly located out of woodland and rarely cultivated. Data analysis indicated that all trees greater than 70 cm in diameter belonged to this species. Data from plots surveyed directly also suggest that the three elm species have slightly different habitat preferences. U. laevis prefers riparian habitats, although the major part of its resources is now on potential sites of oak-hornbeam or closely related forests. U. minor even more often than U. laevis occurs at less humid sites (mostly potential sites of oak-hornbeam or closely related forests), while U. glabra prefers moist slopes. In general, it appears that the impact of DED in the last 20–30 years has been smaller than in the preceding period, however, the disappearance of the disease has not been established. Undoubtedly, U. laevis is the elm species that is least impacted by DED

    Opis:
    Background. Due to specific requirements of service, Border Guard officers should be characterized by good health. Whereas there is lack of studies assessing nutritional status as well as dietary behaviours among Polish Border Guard officers. Objective. The aim of the study was to assess the impact of dietary behaviours of the Polish Border Guard officers on the Fat Mass Index. Material and methods. The study was carried out with participation of 250 Border Guard officers (187 men and 63 women), aged 37±6; years of service: 12±6. Nutritional status was determined with the electrical bioimpedance method using the TANITA MC-780 analyzer. According to the calculated Fat Mass Index value each person was qualified to one of the following groups: fat deficit, normal fat or excess fat. The Border Guard officers were asked to fill in the original questionnaire containing questions about nutritional behaviours in line with the recommendations of the Swiss Food Pyramid for Athletes in the basic version. Results. The excessive amount of fat in every third officer of the Border Guard and numerous irregularities in eating behaviours were found. According to the food pyramid the smallest scale of rational dietary choices (especially regularity of meals, fruit and vegetable consumption) was characteristic of officers with excess fat. In addition, officers from the excess fat group obtained, on average, a lower sum of points for compliance of nutritional behaviours with the recommendations of the Swiss Food Pyramid than those from other groups (49% vs. 59% and 56%, p=0.002). Conclusions. There is a need for nutritional education and further monitoring of both the nutritional status and dietary behaviours of Border Guard officers.
    Wprowadzenie. Z uwagi na specyfikę służby funkcjonariusze Straży Granicznej powinni charakteryzować się dobrym stanem zdrowia. Tymczasem brakuje badań na temat stanu odżywienia, jak również zachowań żywieniowych funkcjonariuszy Straży Granicznej w Polsce. Cel. Celem badań była ocena wpływu zachowań żywieniowych na Wskaźnik Tkanki Tłuszczowej funkcjonariuszy Straży Granicznej pełniących służbę w Polsce. Materiał i metody. Badania przeprowadzono w 2018 roku z udziałem 250 funkcjonariuszy Straży Granicznej (187 mężczyzn i 63 kobiet) w wieku 37±6 lat, pełniących służbę od 12±6 lat. Stan odżywienia oceniono metodą elektrycznej bioimpedancji z użyciem analizatora TANITA MC-780. Na podstawie obliczonej wartości Wskaźnika Tkanki Tłuszczowej każdą z osób zakwalifikowano do jednej z następujących grup: zbyt niska ilość tkanki tłuszczowej, prawidłowa ilość tkanka tłuszczowa lub nadmierna ilość tkanki tłuszczowej. Funkcjonariuszy poproszono o wypełnienie autorskiego kwestionariusza ankiety, zawierającego pytania na temat zachowań żywieniowych zgodnych z rekomendacjami szwajcarskiej piramidy żywienia dla sportowców w wersji podstawowej. Wyniki. Stwierdzono nadmierną ilość tkanki tłuszczowej u co trzeciego funkcjonariusza Straży Granicznej oraz liczne nieprawidłowości w zachowaniach żywieniowych tych osób. W odniesieniu do piramidy żywienia najmniejszą skalą racjonalnych wyborów żywieniowych (w szczególności dotyczącą regularności posiłków oraz spożycia owoców i warzyw) charakteryzowali się funkcjonariusze z nadmierną tkanką tłuszczową. Ponadto, funkcjonariusze z nadmierną ilością tkanki tłuszczowej uzyskali średnio niższą sumę punktów za zgodność zachowań żywieniowych z zaleceniami szwajcarskiej piramidy żywienia niż badani z pozostałych grup (49% vs 59% i 56%; p=0.002). Wnioski. Istnieje potrzeba edukacji żywieniowej oraz dalszego monitorowania zarówno stanu odżywienia jak i zachowań żywieniowych funkcjonariuszy Straży Granicznej.

    Opis:
    Effects of post−harvest wood−debris utilization and pre−planting soil preparation in clear−cut forest on the community structure of soil fungi and bacteria and their possible biological activity towards Armillaria and Heterobasidion were studied in 1− and 10−year−old Scots pine plantations in Bierzwnik and Międzychód Forest Districts (W Poland). Post−harvest wood−debris utilization included: (i) removal from the surface, (ii) spread of the coarse or chipped wood−debris on the surface and (iii) mixing of the chipped wood debris with the soil. Pre−planting soil preparation included: (i) deep furrowing, (ii) shallow turning of the topsoil, (iii) ridging and (iv) no ground preparation. The soil−dilution method was used for detection of fungi and bacteria in soil. Morphotyping was used for identification of fungi. Phenotypic traits and biochemical properties were used for identification of bacteria. Molecular method, MID−66 or BIOLOG® systems were additionally applied for identification of the most common bacteria. Removal of post−harvest wood−debris from the surface of the clear−cut land and shallow turning of the topsoil or ridging before planting increased abundance of fungi in soil of 1−year−old Scots pine plantation. Deep furrowing resulted in increased abundance of fungi and no ground preparation in increased abundance of bacteria in soil of 10−year−old Scots pine plantation. Increased abundance of fungi and bacteria was associated with increased abundance of taxa considered as antagonistic to Armillaria and Heterobasidion. Removal of the post−harvest wood debris and moderate or no mechanical intervention into the soil habitat on the clear−cut site before planting of Scots pine seedlings seems to create the habitat, which may be beneficial for the growth of young trees.

    Opis:
    Dutch elm disease (DED) still occurs in Poland. Previous studies confirmed occurring O. ulmi and two subspecies of O. novo-ulmi: subsp. novo-ulmi and subsp. amerciana. In this study the population of Ophiostoma occurred in Poland was investigated. The disease incidence was investigated on elms growing in 39 locations. The pathogen’s mycelium was isolated from elm branches and twigs collected from 22 plots. The disease symptoms were noted in 5% to 35% trees. Fungi were identified based on the PCR amplification of the ITS 1/2 rDNA together with phylogenetic analysis of this region. Ophiostoma novo-ulmi was the only agent caused DED on Ulmus glabra, U. minor and U. laevis. There were no genetic diversity of O. novo-ulmi Polish population in analyzed ITS region. All kind of specific symptoms and disease intensity occurred independently on elm species and host age. Ulmus minor was infested most sever among the three elms species.

    Opis:
    Effects of different pre-planting soil preparations and post-harvest wood debris applications in a clear-cut Scots pine plantation, on the abundance, diversity, and activity of culturable microorganisms were investigated. The investigation was done 9 years after the re-plantings had been done. This formed part of an investigation of silvicultural practices for conservation and the biological control of Armillaria and Heterobasidion in northern temperate forests (Poland). The treatments being compared, were expected to have altered the soil’s physical and chemical properties, and consequently, its biological properties. Only soft-rot microfungi from the Ascomycota and Zygomycota were detected in the soil. Fungi, including those antagonistic to Armillaria and Heterobasidion, were more abundant after shallow ploughing than after deep ploughing or ridging, and where chipped rather than coarse wood debris was left on the soil surface or incorporated. Scots pine trees had the most biomass and the least mortality after ridging and leaving coarse wood debris on the surface (associated with only a relatively moderate abundance of fungi).
