Fluctuating asymmetry of leaves of mountain ash (Sorbus aucuparia L.) as a bioindicator of aerotechnogenic pollution of the city of Orenburg
An assessment of environmental pollution in the city of Orenburg was conducted using the fluctuating asymmetry method. The common mountain ash was chosen as an environmental indicator. Leaf collection took place at seven points in the city with varying anthropogenic loads. The research aimed to determine the impact of aerotechnogenic pollution on the magnitude of the fluctuating asymmetry of the leaf blade of the populations of mountain ash within the city of Orenburg. The study revealed that...
The epiphytic lichens growing on roadside deciduous trees in the north-west of the Kaliningrad region
This article presents the first attempt to study the fruticose and foliose lichens of the pre-war plantings alongside minor roads in the Slavsk district of the Kaliningrad region. It is the first study of the deciduous roadside plantings in this area. The authors determined predominant species, analysed the wood species composition and came to the conclusion that the predominant ones were the species of the ash and tilia genera, while the number of lichen species was estimated at 29.
