“…London plane (Platanus × acerifolia) is one of the leading tree species in European cities capable to grow across a range of climate zones (Henry and Flood 1919;Browicz 1964;Mimet et al 2009). It has been described to be resilient to urban pollutants, infestations, and severe drought (Dineva 2004;Ivanová et al 2007;Pourkhabbaz et al 2010;Gillner et al 2015;Yang et al 2015;Adamska 2019), and mitigates heat stress through transpiration-induced cooling, which is particularly effective during periods of high atmospheric evaporative demand (Bowden and Bauerle 2008;Ennos 2012;Lindén et al 2015;Sanusi and Livesley 2020). Transpiration-induced cooling even remains operational during nighttime when stable nocturnal boundary layers typically limit air mixing (Lindén et al 2016).…”

BackgroundBark exfoliation is a common feature of London planes (Platanus×acerifolia) that reportedly increases during periods of drought-induced stem shrinkage. Here, we explore the spatial patterns and potential drivers of plane bark exfoliation in Mainz, a central European city of 220,000 inhabitants, following the exceptional summer drought of 2018.MethodsWe estimate the degree of bark exfoliation of 349 urban plane trees across the city and use stem microcores to analyze their tree-ring widths from 2006 to 2019. Further to impervious cover, settlement structure and vegetation cover in the vicinity of each tree, we investigate the relationships between bark exfoliation and tree, site, and climate factors.ResultsResults indicate that plane bark exfoliation correlates significantly with tree size and inner bark width (bothp< 0.001) but is independent of impervious cover and local site conditions. Similarly, stem growth does not change within the city underlining the resilience of London planes to cope with highly diverse urban site conditions. Plane tree-ring widths were only weakly associated with exfoliation estimates (p< 0.05) but strongly controlled by cold season temperatures (p< 0.001).ConclusionAs tree growth was also not affected by summer drought, potential detrimental effects by limited infiltration, increased runoff and altered evaporation are of less concern for the plane trees in Mainz. Projected winter warming is likely to enhance urban plane growth in upcoming decades.

“…Despite so many investigations on natural antagonistic interactions between microorganisms, the phenomenon of hyperparasitism in the urbicenosis is still poorly understood. So far, there have been few such studies on the presence of superparasites on plant pathogens in cities (Czerniawska & Adamska, 2007;Czerniawska et al, 2011;Madej & Antoszczyszyn, 1965;Ruszkiewicz-Michalska, 2010;Sucharzewska et al, 2011Sucharzewska et al, , 2012aSucharzewska et al, , 2012b, and they have mainly aimed at observing the emergence of pathogens on plants, their biology and their impact on the health of host plants, with no account taken of the prevalence of antagonistic microorganisms (Adamska, 2012(Adamska, , 2019Frużyńska-Jóźwiak & Andrzejak, 2007;Mazurkiewicz-Zapałowicz et al, 2012;Piątek, 2003;Werner & Gołębniak, 2010). e city is a dynamic biocenosis with specific and continuously changing conditions, where the introduction of new, sometimes invasive plant species also promotes the presence of parasites, reducing the aesthetic and recreational values of the urban vegetation.…”

The research aimed to study the extent of fungicolous fungi prevalence on the thallus of fungi parasitic to the plants of the urban environment and to assess the species diversity of these microorganisms, with particular attention paid to the phenomenon of hyperparasitism. The research material consisted of herbaceous plants, trees, and shrubs showing signs of infestation by fungi, planted as park plants, along communication arteries, for hedges or ornamental plants, collected in larger cities of north-eastern Poland. Macroscopic and microscopic analysis revealed the presence of 12 different species of fungicolous fungi. The greatest diversity was found on the parasite of Alcea rosea, i.e., Puccinia malvaceraum, on which four fungal species were recorded. Four species of hyperparasites were identified: Ampelomyces quisqualis on the thallus of 19 Erysiphales species,Cladosporium uredinicola on the thallus of 5 species of the Pucciniales order, Clonostachys epichloë on Epichloë typhina, and Sphaerellopsis filum on the thallus of 11 representatives of Pucciniales. The study was also the first to record the presence of superparasites: Ampelomyces quisqualis on four Erysiphales species and Sphaerellopsis filum on three Pucciniales species. It is difficult to determine the relationships established by the other identified fungicolous fungi due to the lack of literature data. Nevertheless, the study demonstrated the presence of, among others, Stemphylium sarciniforme structures inside Erysiphe palczewskii appendages and the absence of ascospores inside the fruiting bodies indicative of the invasive nature of this relationship. However, confirmation of these findings requires further detailed microscopic and molecular analyses.

A total of 103 tree and shrub samples infected with powdery mildew were collected during 2002–2019 from locations within parks, botanical gardens and urban green areas within the Czech Republic and the powdery mildews were morphologically analyzed and identified. The most frequently represented genera were: Erysiphe (27, including former genera Microsphaera and Uncinula), Podosphaera (11, including former genus Sphaerotheca), Phyllactinia (3), Sawadaea (2) and Arthrocladiella (1). New records for the Czech Republic were: E. (U.) arcuata, E. (M.) deutziae, E. (M.) euonymicola, E. (U.) flexuosa, E. (M.) platani, E. (M.) symphoricarpi, E. (M.) vanbruntiana var. sambuci-racemosae, E. (U.) ulmi, Po. amelanchieris, Po. (Sph.) pruinosa and Po. (Sph.) spiraeae. The results were compared with the spectrum of powdery mildew species in the surrounding countries (Slovakia; Hungary; Poland and Germany (Bavaria)).
