Cím:Evaluation of groundwater quality in the rural environment using geostatistical analysis and WebGIS methods in a Hungarian settlement, Báránd / Dániel Balla, Emőke Kiss, Marianna Zichar, Tamás Mester

Megjegyzések:The evaluation, visualization of environmental data from long-term monitoring and making them accessible in a processed form in user-friendly interfaces on the internet are important tasks of our time. The pollution of groundwater resources in settlements is a global phenomenon, the mitigation of which requires a number of environmental measures. In this study, water quality changes following the construction of a sewerage network were examined in the course of long-term monitoring between 2013 and 2022, during which 40 municipal groundwater wells were regularly sampled. Classifying the monitoring data into pollution categories based on water quality index (WQI) and degree of contamination index (Cd), a high degree of contamination was found in the period before the installation of the sewerage network (2014), as the majority of the wells were classified as contaminated and heavily contaminated. In the monitoring period following the installation of the sewerage network, a significant positive change was found in the case of most of the water chemical parameters tested (EC, NH4 + , NO2-, NO3 - , PO4 3- ). Based on interpolated maps, it was found that an increasing part of the area shows satisfactory or good water quality. This was confirmed by the discriminant analysis as well, as it is possible to determine with an accuracy of 80.4% whether the given sample originates from the period before or after the installation of the sewerage network based on the given water chemical parameters. However, 8 years after setting up the sewerage network, the concentration of inorganic nitrogen forms and organic matter remains high, indicating that the accumulated pollutants in the area are still present. To understand the dynamics of purification processes, additional, long-term monitoring is necessary. Making these data available to members of the society can contribute to appropriate environmental measures and strategies.

Cím:Microplastics in water, sediments, and fsh at Alpine River, originating from the Hindu Kush Mountain, Pakistan: implications for conservation / Muhammad Bilal, Abdul Qadir, Atif Yaqub, Habib Ul Hassan, Muhammad Irfan, Mehmood Aslam
Dátum:2023
ISSN:0944-1344 1614-7499
Megjegyzések:Microplastics (MP) pollution is an emerging threat to life and the environment. These particles are not restricted to human-inhabited lands but also found in different mountains and glaciers where the human population is relatively low. These MPs make their way to the river ecosystem from glaciers, rains, and municipal and industrial effluents. The current study was designed to highlight MPs' pollution in water, sediments, and fishes of the Swat River: originating from the Hindu Kush Mountain Range. These samples were collected from eight different sites across the river. An average concentration of MPs detected in water samples (305.79 +/- 289.66 MPs/m(3)), fish (12.54 +/- 8.02 MPs/individual), and sediments (588.29 +/- 253.95 MPs/kg). The highest concentration was observed among water samples at Mingora city and the lowest at the confluence point of the rivers near Charsadda being 753.71 +/- 330.08 MPs/m(3) and 57.64 +/- 31.98 MPs/m(3), respectively. MP concentrations in the sediment samples were also the highest at Mingora city (834.0 +/- 367.21 MPs/kg), and lowest at Chakdara (215.0 +/- 20.0 MPs/kg). Among the fish samples, Schizothorax plagiostomus contained the highest while Wallago attu contained the lowest MP concentrations corresponding to 17.08 +/- 8.27 MPs/individual and 5.0 +/- 2.36 MPs/individual, respectively. Fibers were the most prevalent MPs in all the matrices representing 80%, 92%, and 85% of the total MP count in water, sediments, and fish samples. These findings highlighted that freshwater ecosystem are not free from MPs and are as much vulnerable to anthropogenic activities as marine ecosystem. Therefore, need attention not less than marine ecosystem awareness, education, ecotourism, sustainable reduction in plastic use, and strict rules and regulations could be helpful to prevent the anthropogenic menace.

Cím:Honeybee (Apis mellifera) mediated increased reproductive success of a rare deceptive orchid / É. Biró, J. Bódis, T. Nagy, J. Tökölyi, A. Molnár V.
Dátum:2014
ISSN:1589-1623 1785-0037
Megjegyzések:Honeybees are the most numerous and significant among insect pollinators, but despite their significance their potential role in increasing the reproductive success of threatened European orchids remains largely unexplored. In this study we aim to evaluate the effect of apiary proximity on the fructification rate of the rare and endangered Adriatic Lizard Orchid (Himantoglossum adriaticum H. Baumann). To do so, first we quantified the reproductive success (fruit set) of the Adriatic Lizard Orchids in a Hungarian population in close proximity to a honeybee apiary at Nagytevel. Then we compared the reproductive success in this population to the reproductive success in 3 other Hungarian, 4 Croatian populations (observed during the same year, 2013) and further 4 populations from Hungary (studied in previous years, 1992?2011) with no apiaries in the close proximity of these. The realised 61.7 % fruit set at Nagytevel is the highest reproductive success ever recorded for this species. The importance of apiaries is further emphasised by the fact that the reproductive success of Lizard Orchid individuals decreased significantly with increasing distance from the apiary. Our results provide empirical support for the conservation importance of apiculture and suggest promising results for practical application of apiaries in the conservation of of deceptively pollinated orchids characterised by lower fruit set (e.g. Orchis, Anacamptis, Himantoglossum).

Cím:Grassland fires in Hungary : experiences of nature conservationists on the effects of fire on biodiversity / Deák Balázs, Valkó Orsolya, Török Péter, Végvári Zsolt, Hartel Tibor, Schmotzer András, Kapocsi István, Tóthmérész Béla
Dátum:2014

Megjegyzések:Fire as a natural disturbance has been present in most European grasslands. Controlled burning was also an important component of the traditional landscape management for millennia. It was mainly used to reduce litter and woody vegetation and to maintain open landscapes suitable for farming. Due to socio-economical changes traditional and sustainable use of fire was ceased and replaced by arsons and technical fires in Europe. Despite its wide application in the past and the considerable extension and frequency of current grassland fires, the impact of fire on the grassland biodiversity is still scarcely documented in Europe. The aim of this study is to offer a perspective on the issue of fire impact on grasslands, by overviewing published information and practical experiences from Hungary. Our results suggest that fire can be detrimental for several taxa (e.g. insects or ground-dwelling birds), but can also promote population growth of several endangered species by reducing litter or by creating and maintaining open habitats. We also found that fire may be effective in controlling invasive plant species. The effect of fire on grassland biodiversity may be rather context-dependent. There is a critical need for developing robust evidences on the context-dependence of fire effect on biodiversity. For this, well designed prescribed burning experiments are crucial.

Cím:Survival of fish upon removal of cyanide from water / Mariann Gacsi, Ildiko Czegeny, Gabor Nagy, Gaspar Banfalvi
Dátum:2005
ISSN:0013-9351
Megjegyzések:The effects of potassium cyanide and the removal of cyanide from water in vivo on the survival of fish were investigated. This research was initiated because of the catastrophe that took place at the end of January 2000 in the Carpathian basin, when an enormous amount of cyanide pollution swept through the Samos and Tisza rivers, and then to the Danube. Since nothing was done against the disaster, we have suggested a chemical solution to remove cyanide from waterways (Chem. Innovat. 30 (2000b) 53). Based on experiments, we describe that the most effective and harmless way to remove cyanide and to save the lives of fish from 40 to 160 x the lethal doses of cyanide is to use carbogen gas containing 5% carbon dioxide and 95% oxygen followed by aeration with air.

Cím:Occurrence pattern analysis of dragonflies (Odonata) on the River Tisza between Vilok and Huszt based on exuviae / Kolozsvári István, Szabó László József, Dévai György
Dátum:2015
ISSN:1589-1623 1785-0037
Megjegyzések:Dragonfly exuviae were collected between 2010 and 2013 in the following sections of River Tisza: Vilok (Tiszaújlak), Nove Szelo (Tiszaújhely), Tiszobikeny (Tiszabökény), Vinohragyiv (Nagyszőlős) and Huszt (Huszt). Based on the examination of the 1965 exuviae, collected from 13 main channel sections, 6 dragonfly species were identified [Gomphus vulgatissimus (Linnaeus, 1758), Gomphus flavipes (Charpentier, 1825), Onychogomphus forcipatus (Linnaeus, 1758), Ophiogomphus cecilia (Fourcroy, 1785), Calopteryx splendens (Harris, 1782), Platycnemis pennipes (Pallas, 1771)]. Summing up the collected exuviae, the two most frequent species were G. vulgatissimus (57.3%) and O. forcipatus (39.08%), however significant assemblages of O. cecilia (1.93%), G. flavipes (1.17%), C. splendens (0.36%) and P. pennipes (0.15%) could be found as well. In compliance with the Mantel test the channel and riverbank characteristics show a significant correlation with the composition of dragonfly assemblages (R=0.309, p=0 024). According to the canonical correspondence analysis (15 habitat characteristics) the exuviae data of G. vulgatissimus are connected with the extent of plant coverage, the closure of foliage and the characteristics of riverbanks; the exuviae data of O. forcipatus are associated with water depth, channel deepening tendency, water temperature and type of plant coverage on the river bank.

Cím:Similarity assessment of natural landscapes based on taxonomic distance / Mezősi G., Csorba P., Bata T., Blanka V., Ladányi Zs.
Dátum:2016
ISSN:1589-1623 1785-0037
Megjegyzések:The degree of similarity/dissimilarity between landscapes is important information for landscape classification, potential assessment and evaluation. In geographical assessments, similarity in landscape functioning and visual attributes is commonly analysed by using landscape factors (e.g., relief, water balance and soil fertility), land use and built-up area. In this study the similarity and dissimilarity of Hungarian landscape units were investigated to reveal the appropriateness and uncertainty of the current delimitation methods. Nine indicators for 230 landscape units, delineated by the traditional methods, were integrated into a data matrix. Dissimilarity coefficients were calculated for each unit to determine the Euclidean distance between all indicators. Dissimilarity analysis was performed by multidimensional scaling using Kruskal's stress test and hierarchical clustering. The applied method enabled a more objective determination of taxonomic distance. Based on the results, the similarity and dissimilarity of landscapes could be evaluated by more accurate and quantitative datasets. Several neighbouring landscape units should require increased attention in spatial planning because these landscapes differ from each other: they belong to different clusters based on the investigated indicators, though they are adjacent.

Cím:No evidence for historical declines in pollination success in Hungarian orchids / Molnár V. A., Löki V., Takács A., Schmidt J., Tökölyi J., Bódis J., Sramkó G.
Dátum:2015

Megjegyzések:Pollination crisis (the decline of pollinatorpopulations) is a global phenomenon which threatens biodiversity, human welfare and economy. The degree to which different plant populations/species are affected by pollination crisis is still unclear. In this study, long-term herbarium dataset was used to quantify the reproduction rate of Hungarian orchids between 1853 and 2008. We quantified fruit-set rate of 663 specimens belonging to 27 species. Data were available from an average of 10.3-9.3 localities, 76.5-43.2 years, and 23.4-25.6 specimens per species. Herbarium data were validated with field-observed data in case of the different pollination strategies. According to our results, the reproductive success of the vast majority of orchid species has not changed during time and pollination crisis is not apparent in Hungary at least until the end of the 20th century.

Cím:Pollution Assessment Based on Element Concentration of Tree Leaves and Topsoil in Ayutthaya Province, Thailand / Vanda Éva Molnár, Edina Simon, Sarawut Ninsawat, Béla Tóthmérész, Szilárd Szabó
Dátum:2020
ISSN:1661-7827 1660-4601
Megjegyzések:Atmospheric aerosol particles containing heavy metal contaminants deposit on the surface of plant leaves and the topsoil. Our aim was to reveal the pollution along an industrial-urban-rural gradient (IURG) in the central provinces of Thailand. Leaf samples from Ficus religiosa and Mimusops elengi were collected along with topsoil samples under the selected trees. Al, Ba, Ca, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, and Zn concentrations were determined by ICP-OES in soil and plant samples. Soils were not polluted according to the critical value; furthermore, the elemental composition did not differ among the sampling sites of the IURG. The rural site was also polluted due to heavy amounts of untreated wastewater of the adjacent Chao Phraya River. Bioaccumulation factors of Ba, Cu, and Mn was higher than 1, suggesting active accumulation of these elements in plant tissue. Our findings proved that the deposition of air pollutants and the resistance to air pollutants in the case of plant leaves were different and that humus materials of the soils had relevant role in bioaccumulation of Al, Ba, and Cu. At the same time, the geochemical background, the source of pollution, and the local plant species greatly influence the metal content of any given environmental compartment.

Cím:Statistical aspects of environmental risk assessment of GM plants for effects on non-target organisms / Joe N. Perry, Cajo J.F. ter Braak, Philip M. Dixon, Jian J. Duan, Rosie S.

Megjegyzések:Previous European guidance for environmental risk assessment of genetically modified plants emphasized the concepts of statistical power but provided no explicit requirements for the provision of statistical power analyses. Similarly, whilst the need for good experimental designs was stressed, no minimum guidelines were set for replication or sample sizes. Furthermore, although substantial equivalence was stressed as central to risk assessment, no means of quantification of this concept was given. This paper suggests several ways in which existing guidance might be revised to address these problems. One approach explored is the ♭bioequivalence' test, which has the advantage that the error of most concern to the consumer may be set relatively easily. Also, since the burden of proof is placed on the experimenter, the test promotes high-quality, well-replicated experiments with sufficient statistical power. Other recommendations cover the specification of effect sizes, the choice of appropriate comparators, the use of positive controls, meta-analyses, multivariate analysis and diversity indices. Specific guidance is suggested for experimental designs of field trials and their statistical analyses. A checklist for experimental design is proposed to accompany all environmental risk assessments.
