Abstract The common beech ( Fagus sylvatica L.) is the main forest-forming species in Slovakia and its share accounts for over 31% of total forest area this country. Recently, there are more reports deterioration health Europe, incl. as a result action pathogens genus Phytophthora . aim study to confirm presence forests Slovakia. Ten plots central western were selected study. of: P. x cambivora...

Two independent experiments were conducted to investigate the influence of rhizosphere bacteria on the growth of Anthoxanthum odoratum and Panicum sphaerocarpon. We tested whether host-specific populations of Bacillus mycoides affected the growth of their Anthoxanthum and Panicum hosts and whether host-specific differences in Bacillus populations modified the strong detrimental effect of the ro...

The aim of our study was to evaluate the abundance of cyanobacteria and microcystins in four Sardinian reservoirs (Italy) characterised by different trophic status to define a reference picture for future changes. Increasing levels of eutrophication and the abundance of cyanobacteria are expected to occur due to climate change, especially in the southern Mediterranean. Consequently, an in-depth...

489–497). Three papers utilize molecular phylogenetic approaches to systematics. Traditional groupings and most species of Physconia are confirmed as distinct, although doubt is shed on the monophylly of two species pairs (pp. 498–505). The Lecanora rupicola group is shown to be distinct from Lecanora s. str., with the species containing sordidone as well as having pruinose apothecial discs (pp...

Species in the genus Calonectria (Hypocreales) represent an important group of plant pathogenic fungi that cause serious losses to plant crops in tropical and subtropical climates. Calonectria leaf blight is currently one of the main impediments to Eucalyptus cultivation in Brazil, and various species of Calonectria have been associated with this disease. Since most previous identifications wer...

Algal blooms occur in freshwater bodies throughout the world, often leading to fish kills. Cases of these kills along Ural River were reported 2018–2019, involving significant amount sturgeon farming areas. In this study, analysis algal samples from delta up 100 km inland was carried out August December 2019 using imaging flow cytometry (IFC), molecular biological, and microscopic techniques. W...
