Opis:
During long-term (1998-2000) studies on rodent parasite populations in Mazury lake district there were collected and analyzed data on co-occurrence of intestinal protozoa (Cryptosporidium parvum, Giardia spp.) and helminths. There were performed 178 autopsies of common vole Microtus arvalis, 85 autopsies of yellow-necked mouse Apodemus flavicollis and 386 autopsies of bank vole Clethrionomys glareolus. Positive effect of helminth infections was found in C. glareolus. Voles infected with nematode Heligmosomum mixtum showed higher prevalence of C. parvum and Giardia spp. than voles infected with Heligmosomoides glareoli. The host age took part in these interactions and positive effect of co-occurrence was mainly observed in voles older than 3 months. The other intrinsic (host sex) or extrinsic (season and year of study) factors influenced interactions between parasites. Presented results revealed that helminth infections may facilitate chronic infections of intestinal protozoa in rodent populations.

Opis:
Erysiphe alphitoides causes the most common disease of assimilation apparatus of oaks of different age. It is believed that the pathogen overwinters in buds of the host plant or in the cracks of the bark. The aim of the study was to search for the presence of E. alphitoides in buds, leaves, and wood of sessile oak shoots using molecular techniques. Two hypotheses have been tested: (i) oaks are infected by E. alphitoides, and (ii) the pathogen overwinters in the host plant buds. The samples used in the study were collected form sessile oak trees (Miradz Forest District; 52°41'23.197'N, 18°25'33.942'E) in 2017, and consisted of dormant buds (collected in May), young leaves (collected in June), leaves with visible symptoms of the disease (collected in August), shoot with sip and surface layers of wood (collected in December). Additional part of buds was collected in May 2018. The PCR reaction was carried out with primers specific for E. alphitoides and E. hypophylla. For species identification Sanger method was used. The resulting sequences were compared using BLAST algorithm with reference sequences deposited in the NCBI database. Sequences from isolates obtained from leaves showed 97−99% similarity to the reference sequence of E. alphitoides. Pathogen did not occur in the superficial layers of shoots and buds. As some studies show, at very low temperatures (below –20°C), the mycelium of the pathogen dies, therefore further study should be undertaken on wintering of the pathogen causing the powdery mildew disease on oaks. It also should be examined whether the pathogen overwinters in the form of bagnial spores produced in chasmothecia overwintering on leaves, in the leaf buds, or in bark cracks, and whether the wintering site of the pathogen is related to the age of trees and or to the stands where the trees grow.

Opis:
Application of the correct methods of study is essential for a proper description and understanding of natural communities of microorganisms and their relationships. Classical methods used for detection and identification of soil microorganisms resulted in underestimation of the microbiota. It has been claimed that classical methods, based mainly on morphology, led to the identification of only 1% of the soil microbiota, usually species that predominate in culture because of their fast growth and abundant sporulation. Molecular methods allow rapid, accurate, sensitive and cost−effective identification and enumeration of microorganisms. They are designed to replace and/or support classical approaches. This review summarizes some of the current and emerging nucleic acid−based molecular approaches used for detection, discrimination and quantification of microbes in the environment, mostly in soil.

Opis:
Black cherry is an important invasive species in forest ecosystems in Poland. It developed mainly in Scots pine stands. The aim of the study was to identify microscopic fungi colonies inhabiting black cherry stumps. In the spring of 2017, wood samples were collected from stumps created after cutting in each subsequent month of 2016 in the Podanin Forest District (19°28'00'E, 52°04'00'N). Stumps up to 5 cm and more than 5 cm in diameter were selected for the study. In total, 72 discs from the first stage of the decomposition of wood were collected. The discs were drilled to obtain fine sawdust for further analysis. The trials were divided into four periods. DNA isolation was performed using the Plant Genomic DNA purification kit (ThermoScientific). The ITS1/2 rDNA region was used for species identification. The analysis was carried out using specific primers. The obtained product was purified and sequenced using the Illumina SBS technology. The resulting sequence was compared using the BLAST algorithm with reference sequences from the NCBI database. The communities of fungi inhabiting the black cherry stumps differed from each other. The highest number of taxa was identified in samples from stumps over 5 cm sheared in autumn and winter, while the lowest in stumps up to 5 cm sheared in spring and winter. Fungi belonging to the Ascomycota and Basidiomycota, Blastocladiomycota, Glomeromycota, Zygomycota and non−cultivable fungi and organisms belonging to other kingdoms were identified. Saprophytes from Menispora sp. dominated on the analysed stumps. The collection of fungi of larger stumps was more diverse and more numerous than on stumps with a smaller diameter. A greater diversity of taxa was distinguished by the stumps of tree fallen in the growing season. The majority of the analyzed samples were dominated by Ascomycota. Basidiomycota clusters dominated in the winter. The predominant share of saprotrophs shows the distribution of stumps. The most desirable effect of the research would be the indication of naturally occurring saprotroph, whose operation would reduce the black cherry’s yield strength. The applied method of sequencing based on the Illumina System was effective to determine the composition of the fungal population.

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:
Deadwood is an important functional and structural component of forest ecosystems since it regulates nutrient cycling, serves as a carbon (C) pool, increases the C content in the soil, and is a source of resources, including water, for a wide range of saproxylic and non-saproxylic organisms. The abundance and diversity of wood-inhabiting fungi in six fallen, horizontally lying logs of Quercus petraea, in the 1st, 2nd and 3rd decay classes, in the Drawa National Park in Poland in 2015, were studied using the Illumina se- quencing technique. The total number of OTUs obtained (264 307) included sequences of culturable fungi (242 369 = 91.70%) and non-culturable fungi (7 056 = 2.66%). The dead oak wood was colonized by 277 taxa. Culturable fungi of Zygomycota, Ascomycota and Basidiomycota comprised 75% of taxa detected and were represented by 14, 139 and 53 taxa respectively. Non-culturable organisms were represented by 70 taxa. Fungi were classified into 18 groups: (i) typical soft rot fungi, (ii) phytopathogens potentially hazard- ous to trees, (iii) epiphytes and endophytes or weak, opportunistic pathogens, (iv) ectomycorrhizal species, (v) ericoid mycorrhizal species, (vi) crust fungi, (vii) resupinate basidiomycetes, (viii) saprotrophs and soil fungi, (ix) opportunistic human pathogens causing superficial or systemic mycoses, (x) pathogens of warm- or cold-blooded animals, (xi) ascomycetous yeasts, (xii) basidiomycetous yeasts, (xiii) antagonists of fungi, (xiv) producers of metabolites effective against pathogens, (xv) hyperparasites, (xvi) lichen-form- ing species, (xvii) partners of other fungi, (xviii) species rare or uncommon in nature. It was shown that: (i) coarse, woody debris of oak is host to abundant and diverse mycobiota, (ii) abundance and diversity of fungi increase with the decay continuum, (iii) oak logs can be a habitat of phytopathogens potentially haz- ardous to forest health, (iv) different phytopathogens favour wood in different decay classes, (v) abundance of pathogens decreases, and of ericoid mycorrhizal (or soil) species increases with the decay continuum. Maintaining different types of deadwood increases fungal diversity, but also the risk of diseases.

Opis:
Pedunculate oak (Quercus robur L.) is the most valuable deciduous tree species in Poland. For almost 30 years, an oak decline resulting from stress factors leading to a decrease of tree vitality in the long-term has been observed. The aim of the present study was to determine the proportion of leaves infected by the fungus Erysiphe alphitoides, the cause of powdery mildew, in post-flood oak stands situated in the Forest District Wołów (51°32’N, 16°62’E) as well as to evaluate effects of powdery mildew with respect to the oak decline. In order to record the powdery mildew incidence, we selected three trees in each of the ten investigated oak stands, and 200 leaves were collected from the upper part of the crowns. The percentage of infected leaves as well as the reduction of carbon assimilation capacity was assessed. Furthermore, we evaluated the average reduction of carbon assimilation capacity and the percentage of withering branch tips in 25 adjacent trees. Incidences of powdery mildew were observed in seven out of the ten stands. The maximum tree damage did not exceed 22% leaf infection and mean defoliation within the study areas ranged from 18% to 61.4%. Non-withering branch tips were observed in one post-flood area as well as in one area situated outside the flooded region. Within the remaining areas studied, the average proportion of withering branch tips ranged from 0.4% to 13.8%. Statistical analyses showed that differences between the investigated stands with regard to the rate of powdery mildew occurrence were not significant. Correlating the means, however, revealed a relationship between powdery mildew incidence and branch tip withering. This relationship is a possible indication of the ongoing oak dieback. No statistically significant relationship between tree defoliation and powdery mildew incidence was found. The lack of statistical significance, as observed here, implies that water stagnation within the investigated stands had no effect on Erysiphe alphitoides infection.
