Opis:
The purpose of the studies conducted in the years 1996-1998 was to determine the quantitative and qualitative composition of bacterial and fungal communities in rhizosphere of soybean cultivated in monoculture and non-rhizosphere soil. Besides, the proportion of bacteria and fungi, which were distinguished by their antagonistic effect towards soil-borne pathogens was established. A microbiological analysis of 1g of dry weight of soil from rhizosphere of soybean resulted in 3.21 x 10⁶ to 8.70 x 10⁶ bacterial colonies and from 70.51 x 10³ to 123.74 x 10³ fungal colonies. In the case of non-rhizosphere soil, 3.50 x 10⁶ to 4.75 x 10⁶ bacterial colonies and 16.16 x 10³ to 51.38 x 10³ fungal colonies were obtained. Besides, soybean cultivation in monoculture had a negative effect on the number of antagonistic isolates of bacteria (Bacillus spp., Pseudomonas spp.) and fungi (Gliocladium spp., Penicillium spp., Trichoderma spp.). Smaller numbers of antagonistic bacteria and fungi in rhizosphere soil of soybean cultivated in monoculture as compared to non-rhizosphere soil, can prove little biological activity, which results in a worse phytosanitaty condition of the soil.
Przedmiotem badań przeprowadzonych w latach 1996-1998 była gleba ryzosferowa soi uprawianej w monokulturze oraz gleba pozaryzosferowa. Analiza mikrobiologiczna wykazała, że w 1 g s.m. gleby ryzosferowej średnia liczebność bakterii oraz grzybów była większa, aniżeli w glebie pozaryzosferowej. W próbach badanych gleb liczebność bakterii z rodzaju Bacillus była zbliżona. W przypadku bakterii z rodzaju Pseudomonas ogólna ich liczebność była prawie trzykrotnie większa w ryzosferze soi, aniżeli w glebie pozaryzosferowej. Badania laboratoryjne wykazały, że znacznie więcej antagonistycznych Bacillus spp., Pseudomonas spp., Gliocladium spp., Penicillium spp. i Trichoderma spp. wystąpiło w glebie pozaryzosferowej, aniżeli w ryzosferze soi. Mniejsza liczebność antagonistycznych bakterii i grzybów w ryzosferze soi uprawianej w monokulturze może świadczyć o małej aktywności biologicznej mikroorganizmów, co przyczynia się do pogorszenia fitosanitarnego stanu gleby.

Opis:
Scots pine sawdust, composted bark or coarse, post-harvest woody debris from conifers had been spread over the surface of barren forest soil before planting with Scots pine. The effects of the Scots pine sawdust, composted bark or coarse, post-harvest woody debris from conifers on the abundance and diversity of culturable fungi were investigated. The amendments were aimed at increasing the soil suppressiveness to Armillaria and Heterobasidion. The classical soil-dilution method was chosen for qualitative and quantitative analyses of fungal communities in soils because of its proven reliability and consistency. The soil was inhabited by saprotrophic fungi from Ascomycota and Zygomycota, including species known to be potential antagonists of Armillaria or H. annosum (i.e. Clonostachys + Trichoderma spp., Penicillium commune, P. daleae, P. janczewskii) or stimulants of Armillaria (i.e. Pseudogymnoascus roseus, Trichocladium opacum). Eleven years after treatment, the abundance and diversity of fungi, the abundance of P. commune, and locally the abundance of P. janczewskii increased, while Clonostachys + Trichoderma spp., and locally, P. daleae and T. opacum decreased. Amending the barren soil with organic matter does not guarantee effective, long-term suppressiveness of the sandy loam soil to Armillaria and Heterobasidion. Increased abundance of entomopathogenic and nematophagous species, 11 years after treatment, does suggest the long-term possibility of insect or nematode control in soil.

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:
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.

Opis:
The aim of the studies carried out in the natural oak-hornbeam forest Tilio-Carpinetum typicum and in the degenerated form in the stage of pinetization Pinus-Lamniastrum, was to obtain and compare qualitative-quantitative structures of soil fungi communities in two different oak-hornbeam forests. This degenerated form of oak-hornbeam forest is the result of removing the natural tree population (typical oak-hornbeam forest) and re-afforesting the resultant vacant area with pines. The study plots were located in such a way that the variations of soil fungi communities were affected only by seasonal changes in the vegetation of the degenerated oak-hornbeam forest Pinus-Lamnias- trum. The soils in both study plots are typical forest grey-brown podzolic soils (Luvisols). The results of mycoiogical studies indicate significant differences between soil fungi communities in both oak-hornbeam forests, although similarities especially in species composition of 15 of the most abundant fungi species were also found. The differences are the result of changes in the floral composition of degenerated oak-hornbeam forest. In the past, when typical oak-hornbeam forest covered whole studied areas, the soil fungi communities were probably almost the same in both plots. The first change could have happened after the removal of the trees; the second, after the re-afforestation of the resulting vacant area with pines. The re-appearance of Tilio-Carpinetum typicum in its once occupied habitat causes changes in the soil fungi community in the degenerated oak-hornbeam forest.
