Among individual techniques of wood treatment, there are highly significant differences in the greenhouse gas balance. Greenhouse gases have, according to the currently adopted global convention, a major impact on global warming and climate change. Nevertheless, there are also sceptical opinions on the scientific basis of such concept. As well as the natural processes of tree growth and the end of their life cycle, the wood processing technologies also affect the balance of greenhouse gases on Earth. The current natural forest without human intervention does not have to reduce greenhouse gas emissions definitely, but can also be the source of their emissions. Also, technological, particularly thermal, processes have different contribution to the production of greenhouse gases. The submitted paper presents the context of warming and cooling of the Earth during its development with a concentration of carbon dioxide in the atmosphere. Further, the indicative greenhouse gas balance, respectively, CO2 generated at thermal wood processing processes, are analysed.

The results of the potentially toxic elements imput to the representatives of the genus Pinus spp. and Quercus spp. at four selected closed Cu-deposits: Ľubietová (Slovakia), Libiola and Caporciano (Italy) a São Domingos (Portugal) are significantly complicated. The imput of the potentially toxic elements to the plants at mining areas in comparison with reference areas usually markedly differ. At the mining areas show the plants much more bioaccumulation of toxic elements into their organs. The bioavailability of individual toxic elements is mutable but in general relatively limited. Pinus spp. and Quercus spp. are for most elements excluders (bioconcentration factor BCF<1). Only Ag show extraordinary ability to high degree of bioconcentration. Also bioconcentration factor values in Pinus sp. at Ľubietová ore-field show high degree of Pb and Zn accumulation in studied plants. Zinc is in Pinus spp. and Quercus spp. accumulated in needles at all studied deposits. The translocation factor (TF) indicates that the other studied toxic elements are accumulated preferentially in roots. The studied plants are suitable only for phytostabilization of the potentially toxic elements.Web of Science1211079

Humanity has existed in special living conditions since March 11, 2020 when WHO declared COVID-19 a global pandemic. This coronavirus disease has already taken more than 6.55 million of people's lives from almost 625 million of officially confirmed cases of people infected around the world at the beginning of October 2022. Lot of university lecturers, teachers and researchers are concerned by new challenges in the education and science process. Therefore, many new recommendations and methodologies have been published for effective teaching in the pandemic time focusing on different forms of distance digital education. Certainly, the process has been actual for biological disciplines too where the biggest problems appeared with the organisation of field courses. Every country and even every university have been looking for optimal ways within their epidemic situation according to country restriction rules. Therefore, we have generalized this experience, as well as developed proto...

The aim of the presented article was to determine the Hg content in the fruiting bodies of 13 generally consumed mushroom species (Boletus reticulatus, Clitocybe nebularis, Lactarius deliciosus, Macrolepiota procera, Russula spp., Suillus grevillei, Tricholoma spp.) growing at the area of abandoned mercury deposit Malachov. The Hg concentrations were analyzed by thermal decomposition-gold amalgamation atomic absorption spectroscopy, using AMA-254 Advanced Mercury Analyzer. The Hg concentrations in soil varied widely (ranging from 0.01 to 2.44mg·kg-1), furthermore, they were particularly depended on the mushroom species. The fruiting bodies of Russula ochroleuca contained the highest concentrations of Hg (up to 16.69mg·kg-1). The lowest concentrations were detected in Russula aeruginea (from 0.04 to 0.06 in stipe stems and from 0.05 to 0.06mg·kg-1 in pileus) and in Russula vesca (0.05 in stipe stems; 0.09mg·kg-1 in pileus). Mercury is preferentially accumulated in the mushroom pileus...

The article is focused on the application of Energy dispersive micro X-ray fluorescence spectroscopy as a specific method to determine the contents of potentially toxic elements and its spread in plant tissues. As a model species, Quercus spp. were selected. In order to compare the obtained results with previous research, four well-described abandoned Cu-deposits were selected for sampling: Ľubietová (Slovakia), Libiola and Caporciano (Italy), and São Domingos (Portugal). The results of micro X-ray fluorescence spectrometry confirm the irregular contamination of Quercus spp. by potentially toxic elements. The level of contamination is the highest predominantly in the root cortex, where is also the highest Ca contents (with exception of São Domingos). At Ľubietová and Caporciano, high Ni content was described in branches cortex, in branches mesoderm also Fe, Cu and Zn. At the same time, the inhibition influence of Ca was also confirmed regarding the input of these elements into plants.

This article reports the results of a study concerning contamination of the dump-fields by potentially toxic elements at five abandoned copper mines: Ľubietová, Špania Dolina (Slovakia), Libiola, Caporciano (Italy) and São Domingos (Portugal). This paper offers an updated description of soil contamination at the individual deposits and indicates a possible solution of the derived environmental problems. Contamination of technosoils by PTEs at the dump-fields shows an irregular spatial distribution of Fe, Cr, Mn, Co, Ni, Cu, Zn, As, Cd, Sb and Pb. Contents of PTEs often exceed both national and EU law limits. Whereas at Ľubietová, Špania Dolina and Caporciano the environmental risk is limited, at Libiola and São Domingos it seems to be very heavy. The technosoil (slag) of the dump-fields is not well aerated and the soil colloids have (except for Špania Dolina) negative surface charge, so they are suitable for PTEs sorption. The main environmental risk in the mining area of Sao Doming...

Phytosociological and physicochemical studies of endangered habitats of swamp and peat-bog areas were carried out in the Lower Silesian Forest complex (Western Poland), in the vicinity of Węgliniec village. The total of 63 phytosociological relevés were made and three syntaxonomic units were distinguished as associations (Cicuto-Caricetum pseudocyperi, Typhetum latifoliae, Phragmitetum australis) and two as communities (with Sphagnum girgensohnii and with Juncus effusus). Using the phytoindication method, it was found that among four analysed habitat parameters (L – light availability, F – humidity, R – soil pH, N – soil nitrogen), only nitrogen content did not play a significant role in shaping the composition of these phytocoenoses. Physicochemical studies of surface waters using high performance liquid chromatography (HPLC) method indicated, among others, a higher level of nitrogen compounds in some samples. Concentrations of mineral substances dissolved in water usually exceeded...

São Domingos belongs among the most important historic Iberian Pyrite Belt Cu mines. The anthrosoil is contaminated by a very high content of heavy metals and metalloids. The study was focused on evaluating the interaction of some chemical elements (Ca, Mg, Fe, Mn, Cu, Pb, Zn, Ag, Cd, Ni, Co, As, Sb) in the system soil vs. five autochthonous dominant plant species: Pinus pinaster Aiton, Quercus rotundifolia Lam., Agrostis sp., Juncus conglomeratus L. and Juncus effusus L. The plants are heavily contaminated by Cu, Pb, As and Zn. The bioconcentration factor proved that they exhibit features of metal tolerant excluders. The trees are accumulators of Ag, whereas the graminoids are hyper-accumulators of Ag and Juncus effusus of Co. The translocation factor confirmed that the selected elements are immobilised in the roots except for Mn and Zn in Pinus pinaster and Mn in Quercus rotundifolia and Juncus conglomeratus. The bioaccumulation of Mn, Zn and Cu at low pH increases. The increased ...

The knowledge of bryophytes growing on metal-contaminated sites is still insufficient in Slovakia. This study deals with bryophyte flora of three mine heaps (Podlipa, Richtárová and Maximilián) with copper-rich substrate. A total of 54 relevés was made, in which a total of 45 bryophyte species (43 mosses and 2 liverworts) was recorded. Species-richest mine heap was Podlipa with 31 bryophyte species (29 mosses and 2 liverworts) and species-poorest was Maximilián with 20 species of mosses. 11 species were mutual for all three mine heaps, while 9 species where present only on Podlipa, 8 on Richtárová and 4 on Maximilián. The most representative bryophytes, in terms of their occurrence and cover, are Ceratodon purpureus, Pohlia cruda, Dicranum scoparium, Hypnum cupressiforme, Pleurozium schreberi, Brachythecium salebrosumand, Plagiomnium affine. Occurence of bryophytes on metal-contaminated sites was discussed.

Diminished reproduction success in species with narrow distribution ranges might be one of the factors responsible for their limited dispersal and colonization abilities. We investigated here various aspects of the seed biology of the West Carpathian endemic Daphne arbuscula (Thymelaeaceae) and compared it with its more widespread relative D. cneorum. In both species, we investigated (i) differences in seed viability and germination ability; (ii) differences between the two observed fruit morphotype groups, and (iii) the effect of cold stratification in breaking seed dormancy and enhance germination in stored seeds. To determine seed viability, a tetrazolium test and an imbibed cut test were performed. Several seed germination tests with gibberellic acid and with a sequence of cold and warm stratification, using different temperatures and durations, were carried out. We uncovered that (i) D. arbuscula seeds show significantly lower viability than D. cneorum seeds, but this differenc...

The aim of work was to determine of differences in morphometric traits of the model species Arabidopsis arenosa (L.) Law. on the heap and neighbour site on the basic of research realized in growing season 2011 on the heap Maximilian in Spania Dolina. We focused on plant height, width of rosette of leaves, width and length of lowest stem leaf, number of seed per one silique, weight of roots and weight of overground parts. The results were subjected of statistical analysis with the assistance of a Student t-test, idicators of variability and central values.The results show statistically significant difference at height level of confidence for each of the average of measured traits.The results support the hypothesis about influence of heavy metals on the whole habitus of plant and its evolution.

A systematic survey of grassland communities in central Slovakian sub-montane and montane regions (including the Kremnické vrchy Mts., Starohorské vrchy Mts., Veľká Fatra Mts., and Zvolenská kotlina Basin) was performed between 1996 and 2007. The main aim was to identify main environmental gradients in the studied vegetation and to estimate the most important individual variables responsible for the variation of their species composition. Along with the floristic composition, the environmental variables were either recorded in the field (altitude, slope, aspect), calculated (solar radiation, climatic data, and phytochorological affinity), or derived from available maps or GIS digital data layers (type of bedrock, soil parameters). These environmental variables were used as supplementary in the detrended correspondence analysis (DCA) or explanatory in the canonical correspondence analysis (CCA). The affiliation of individual phytosociological relevés to associations was estimated by ...

The environment in the mining territory of abandoned Cu-deposits, at first in the surrounding of dump-fields and tailings in Ľubietová and Špania Dolina villages are contaminated by Sb released from ore minerals. The degree of antimony toxicity is controlled by its speciation, which depend first of all on pH/Eh values. It is the reason why pH/Eh stabilite diagrams enable probable determination of Sb forms present in country components. In sediments and in soil at Ľubietová village prevail antimony in less toxic degree Sb 5+ and is present in SbO 3-form, while in dump-field and in tailing at Špania Dolina village one part of samples characterised by Eh<0,1 values is concentrated in Sb 3+ stabilite fields of valentinite (Sb 2 O 3) and antimonite (Sb 2 S 3). Sb content in groundwater from both studied localities exceed the Regulation of the Slo-vak Republic No. 296/2005 Coll. but these water is used for human consumation only very rarely. The samples from Špania Dolina are in compar...

The light decides about the course and efficiency of photochemical processes, being an important component of the surrounding environment shaping the plant composition in specific conditions. Thymus praecox subsp. praecox belongs to endangered taxa due to preferences for open habitats, which as a result of natural succession are exposed to overgrowth and shading with forest-scrub vegetation. In this study, an attempt was made to check the physiological activity of creeping thyme in changing environmental conditions prevailing on isolated stands in the Ojców National Park (Southern Poland). The increase in fresh and dry mass and the percentage of water in plants were determined, the content of chlorophyll a and b was measured, the intensity of chlorophyll a fluorescence was examined and the degree of electrolytes leakage through cell membranes was checked. The main aim was to determining the optimal habitat conditions for this taxon, which could help protect it. Based on the conducte...

The paper presents results of preliminary research carried out in 2011 in the area of two Protected Sites - CHA Jakub, CHA Kopec and Nature Reserve PR Mackov bok in the buffer zone of the Low Tatras National Park. Six native species and one native hybrid of roses were found there (1 from the Pimpinellifoliae section and 6 from the Caninae section) and their 13 varieties. The most numerous among them are Rosa canina var. dumalis Baker and R. × subcanina (H. Christ) R. Keller. Such great diversity of species and varieties in such a small area (only 20.2 ha) proves considerable floristic richness, and occurrence of habitats preferred by roses.

The paper presents morphological diversity within Rosa dumalis Bechst., species identified among others in the buffer zone and the area of the Low Tatras National Park (Slovakia). This taxon belongs to the polymorphic section Caninae DC. em. Christ., and its morphological differentiation particularly relates to the degree of hairiness and glandularity leaves and the presence or absence glandules on pedicels. Based on these features nine varieties of this species were distinguished in Europe by Popek (1996). Four of these varieties, R. dumalis Bechst. var. afzeliana (Fr.) Boulenger, R. dumalis Bechst. var. dumalis, R. dumalis Bechst. var. caesia (Sm.) Boulenger and R. dumalis Bechst. var. coriifolia (Fr.) Boulenger, were found in the analyzed area.

Heavy metal and metalloid-contaminated soil is a serious barrier to colonization for many plant species. The problem of the elimination of toxic waste accumulated in technogenous soils in many highly transformed regions is extremely important. Hence, another attempt was made to analyze the effect of the addition of sorbents (BCH—biochar, B—bentonite, ChM—chicken manure, OS—organo-zeolitic substrate) to contaminated copper soil on the germination and early growth of Eurasian common grass species (Agrostis capillaris, A. stolonifera, Festuca rubra and Poa pratensis), which could potentially be used in recultivation. This experiment was based on the laboratory sandwich method. Standard germination indexes, morphometry and biomass analysis were used. The percentage of germinating seeds was lower in each of the soil variants and sorbents used compared to the control. Dry mass was positively stimulated by all sorbents. The response to the addition of sorbents, expressed as the electrolyte...

The reclamation of abandoned mining heaps rich in potentially toxic elements (PTEs) is critical for the environment. We carried out a laboratory experiment studying the effects of the addition of four natural sorbents (biochar, bentonite, chicken manure and organo-zeolitic substrate) to soils contaminated with PTEs, predominantly Cu, As and Sb, on the germination and growth of the autochthonous grasses Agrostis capillaris, A. stolonifera, Festuca rubra and Poa pratensis. The experiment used Petri dish tests with water extracts of contaminated soil and soil neutralised with the four sorbents. Standard indexes of the germination process were used (germination percentage, time required for 50% germination index, speed of emergence), and different values were found depending on the plant species and sorbent used. However, the percentage of seeds germinating was lower for each sorbent compared to the control (distilled water). The fresh mass values were positively stimulated by all sorbe...

The conducted experiment was aimed at determining the effect of aqueous extracts from dry roots and shoots of common weed nipplewort (Lapsana communis L. subsp. communis) on seeds germination and early growth of radish (Raphanus sativus L. var. radicula Pers.), cultivars ‘Rowa’, ‘Krakowianka’, ‘Półdługa’. The experiment was carried out in the form of Petri dishes tests with 3 different percentage concentrations of extracts (1%, 3% and 5%, respectively). The germination indexes used here revealed that the germination capacity of the radish seeds was significantly inhibited by extracts from the roots and shoots of L. communis subsp. communis. The elongation growth of radish roots and hypocotyls was stimulated to a higher percentage by extracts from nipplewort roots than by extracts from shoots. The fresh and dry mass of the radish seedlings depended on the type (roots/shoots) and concentration of the extract as well as the radish cultivar. The electrolyte leakage was the highest in se...

Aims and study area: We present the first formalised large-scale syntaxonomic overview of mesic semi-natural grassland communities (Arrhenatheretalia elatioris and Nardetalia strictae) in the Ukrainian part of the Eastern Carpathians and adjacent areas of Hungary, Slovakia and Poland. Methods: During 2009–2014 we recorded 759 phytosociological relevés using the Braun-Blanquet approach. The classification was based on our own phytosociological material as well as published material recorded by both Braun-Blanquet and eco-phyto-cenotic (dominant) approach comprising 2,000 phytocoenological relevés in total (952 relevés in the stratified data set). Semi-supervised and supervised classifications by the K-means method and indirect gradient analysis by detrended correspondence analysis were used for the analyses. Slovak electronic expert system and diagnostic species for grassland vegetation published in national overviews in the neighbouring countries helped us to identify individual clusters. Didukh indicator values were used to compare habitat conditions of delimited plant communites. Results: A total of fifteen well-differentiated associations within five alliances and two classes were delimited: Class Molinio-Arrhenatheretea including the alliance Arrhenatherion elatioris with associations Anthoxantho odorati-Agrostietum tenuis, Betonico officinalis-Trifolietum pannonici, Poo-Trisetetum flavescen-tis, Primulo veris-Agrostietum capillaris and Pastinaco sativae-Arrhenatheretum elatioris and the alliance Cyno-surion cristati with associations Plantagini-Lolietum perennis and Lolio perennis-Cynosuretum cristati. Class Nardetea strictae including the alliance Nardo strictae-Agrostion tenuis with associations Antennario dioicae-Nardetum strictae, Campanulo abietinae-Nardetum strictae and Betonico officinalis-Agrostietum capillaris, the alliance Violion caninae with associations Campanulo rotundifoliae-Dianthetum deltoidis, Hyperico maculati-Deschampsietum flexuosae, Festuco rupicolae-Nardetum strictae and Polygalo vulgaris-Nardetum strictae cari-cetosum fuscae and the alliance Potentillo ternatae-Nardion strictae with association Soldanello hungaricae-Nardetum strictae. The ecological differentiation of syntaxa is mainly based on certain environmental factors reflected in Didukh indicator values (DIV), management practices and altitude. Conclusions: This study complements current knowledge about mesic grasslands from poorly sampled area using the Braun-Blanquet approach. The classified syntaxa of mesic grasslands are discussed with respect to their distribution in the Car-pathians and Europe and we expect that the results of our research will assist in the anticipated future supranational classification of mesic grasslands in the Carpathians.
