Shields against pollution: phytoremediation and impact of particulate matter on trees at Wigry National Park, Poland.

This study examines the impact of airborne particulate matter (PM) and associated trace elements (TEs) on deciduous and coniferous trees at the edge of Wigry National Park in northeast Poland, focusing on pollution levels and the potential for phytoremediation. Researchers measured PM concentrations in the air and on the leaves of , , and , along with photosynthetic indicators (Fv/Fm ratio and performance index). The study found significant differences in pollution intensity across areas with varying levels of human activity.

The attitude towards the forest and satisfaction with life of Polish students.

The aim of the study is to determine the connection between the attitude towards the forest and life satisfaction of students. The study was conducted on a sample of 650 students from Polish universities using The Satisfaction With Life Scale and an original questionnaire measuring the approach towards the forest-LAS scale. There are 3 subscales which measured: the perceived benefits from spending time in the forest; the degree of involvement in exploring the forest and working to its advantage; fears connected with the forest.

Variability of Functional Groups of Rhizosphere Fungi of Norway Spruce ( (L.) H.Karst.) in the Boreal Range: The Wigry National Park, Poland.

Rhizosphere microbial communities can influence plant growth and development. Natural regeneration processes take place in the tree stands of protected areas, which makes it possible to observe the natural changes taking place in the rhizosphere along with the development of the plants. This study aimed to determine the diversity (taxonomic and functional) of the rhizosphere fungal communities of Norway spruce growing in one of four developmental stages.

The effect of herbicides on morphological features of pollen grains in Prunus serotina Ehrh. in the context of elimination of this invasive species from European forests.

Prunus serotina Ehrh. is an alien invasive neophyte widespread in European forests. So far, no effective methods of its elimination have been developed.

Effect of Irrigation Dose on Powdery Mildew Incidence and Root Biomass of Sessile Oaks ( (Matt.) Liebl.).

The sessile oak is one of the most significant forest tree species in Europe. This species is vulnerable to various stresses, among which drought and powdery mildew have been the most serious threats. The aim of this study was to determine the influence of irrigation levels (overhead sprinklers) on the damage caused by powdery mildew to growing in a nursery setting.

Sociodemographic Determinants of Poles' Attitudes towards the Forest during the COVID-19 Pandemic.

Attitudes towards forest ecosystems have been changing together with human needs, which is amplified with society's increasing need to spend recreation time in the forest. The phenomenon has been particularly visible during the COVID-19 pandemic. The aim of this study was to determine the attitude of Poles to forests during the COVID-19 pandemic.

Communities of Fungi in Black Cherry Stumps and Effects of Herbicide.

So far, there have been no studies on fungal communities in (black cherry) wood. Our objectives were to characterize fungal communities from wood and to evaluate effects of glyphosate (Glifocyd 360 SL) used on stumps on abundance, species richness and diversity of those communities. In August 2016, in the Podanin Forest District, stumps of black cherry trees left after felling were treated with the herbicide.

The Effect of Size of Black Cherry Stumps on the Composition of Fungal Communities Colonising Stumps.

We investigated fungal communities colonising black cherry stumps. We tested the hypothesis that black cherry stumps of greater diameter should be characterised by more diverse fungal communities than stumps of smaller diameter. The material for analyses came from Podanin Forest District.
