Cím:Secondary succession in sandy old-fields : a promising example of spontaneous grassland recovery / Ágnes-Júlia Albert, András Kelemen, Orsolya Valkó, Tamás Miglécz, Anikó Csecserits, Tamás Rédei, Balázs Deák, Béla Tóthmérész, Péter Török

Megjegyzések:Question: Based on the spontaneous vegetation development of old-fields in the Nyírség and Kiskunság sand regions (Hungary), we aimed to answer the following questions using the chronosequence method: (1) how do the proportionsof different functional groups change during succession; (2) which target species establish successfully in the old-fields during the course of succession; and (3)how successful is spontaneous succession in the recovery of target grasslands-Location: Two sand regions of the Great Hungarian Plain: (1) the Nyírség sand region (East Hungary, acidic sand, moderately continental climate) and the Kiskunság (Central Hungary, calcareous sand, continental climate).Methods: Altogether 24 old-fieldswere classified into young (<10-yr-old),middle-aged (10-20-yr-old) and late-succession (20-40-yr-old) old-fields; four fields in each age category. For baseline vegetation reference, three open and three closed sand grassland stands in both regions were sampled in the vicinity of the old-fields. The percentage cover of vascular plants was recorded in five 2 X 2-mplots in each field, in early May and late June 2012. We used life forms, clonal spreading traits and Ellenberg indicator values for nutrients in the analysis. Speciesof Festuco-Brometea class were considered as target species.Results: The cover of hemicryptophytes and geophytes increased, the cover of short-lived species decreased with time. Cover of species without clonal spreadingability decreased, while cover of species with clonal spreading ability increased with increasing field age. The cover of invasive species decreased with increasing field age. The majority of target species had established already in the young and middle-aged old-fields, although their cover was significantly higher in the two older age groups.Conclusion: Spontaneous succession can be a vital option in recovery of sand grassland vegetation in Central Europe; the majority of the species pool of sandy grasslands can be recovered in the first 10-20 yrs. However, the success of grassland recovery can be strongly influenced by the surrounding species pool and can be slow if seed dispersal is limited. Spontaneous succession is most promising when the target species of grasslands immigrate at the very beginning of the succession, within the first few years.

Cím:OpenBioMaps - self-hosted data management platform and distributed service for biodiversity related data / Miklós Bán, Gábor Máté Boné, Sándor Bérces, Zoltán Barta, István Kovács, Kornél Ecsedi, Katalin Sipos
Dátum:2022

Megjegyzések:Biodiversity related observational data are collected in a variety of ways and for a variety of purposes, mostly in the form of some sort of organised data collection action. Data management solutions are often developed to manage the data collection processes and organise the data, which may work well on their own but are less compatible with other data management tools. In a continuous development process, we have created the OpenBioMaps (OBM) biodiversity data management platform, which can be used as a self-hosted data management platform and as a free service, hosted by several institutions for biological database projects. OBM has the ability to integrate biological databases without any structural or functional constraints, allowing a high degree of flexibility in data management and development; it provides interfaces to facilitate communication between different end-user communities, including scientists, citizens, conservationists and educational staff. We have also established a network of OBM services based on collaboration between government, educational and scientific institutions and NGOs to provide a public service to those who lack the capacity or knowledge to set up or manage their own self-hosted servers. OpenBioMaps uniquely focuses on the entire data management process, from building the data structure to data collection, visualisation, sharing and processing.

Megjegyzések:Wetlands play a critical role in water purification and biodiversity maintenance, yet many are increasingly affected by anthropogenic pollution. This study provides a comparative assessment of physicochemical, microbiological, and heavy metal parameters in six Algerian wetlands spanning coastal, highland, and desert regions over a full annual cycle (November 2021?October 2022). Twenty-five indicators were measured across polluted and non-polluted sites. Polluted wetlands showed significantly higher turbidity (Z= -3.678, p<0.001), organic matter (Z= -2.123, p=0.04), and heavy metals including Cu (Z= -4.234, p<0.001), Fe (Z= -3.123, p=0.002), and Pb (Z= -3.789, p<0.001). Dissolved oxygen was consistently lower in polluted sites (Z= -2.345, p=0.02). Highland wetlands exhibited elevated nutrient loads, with nitrates (Z=-2.789, p=0.01) and ammonium (Z=-3.123, p=0.002) reflecting agricultural inputs. Microbiological contamination exceeded recommended thresholds at all polluted sites, with fecal coliforms and fecal streptococci surpassing 1000 CFU/100 ml. Seasonal analysis showed higher microbial loads in the wet season and concentration of nutrients in the dry season. Overall, the results demonstrate clear spatial and seasonal variation in water quality, with polluted sites across all regions exceeding national and WHO guideline values for nutrients, heavy metals, and microbiological indicators. These findings underscore the need for strengthened monitoring and pollution-control measures in Algerian wetlands.

Cím:Preservation of diversity and oenological properties of wine yeasts during long-term laboratory maintenance: A study of strains of a century-old Tokaj wine yeast collection / Kállai Zoltán, Pfliegler Walter P., Mitercsák Judit, Szendei Gergő, Sipiczki Matthias
Dátum:2019
ISSN:0023-6438
Megjegyzések:The effect of long-term laboratory maintenance on the biological diversity and certain oenolological properties of wine yeasts was investigated by the analysis of 17 strains isolated from Tokaj (Hungary) wines more than a century ago and maintained since then in culture collections. The analysis of the D1/D2 domains of the large subunit ribosomal RNA genes and the ITS sequences assigned them all to S. cerevisiae but divided them into two groups. One group showed sequence identity with wine strains occurring mainly in countries of the region. The combined results of the interdelta, RAPD, microsatellite-primed PCR (MSP), mtDNA and karyotype analyses found both groups diverse and defined each strain as unique, demonstrating that the long period of maintenance under identical conditions has not resulted in convergent evolution in their genomes. High diversity was detected also in certain phenotypic traits of oenological relevance (osmotolerance, killer phenotype, production of glycerol, ethanol, H2S and volatile acids). In the microvinification experiments all strains performed better than the laboratory strain S288c and were comparable to the industrial strain used as a control or even surpassed it in certain parameters. Thus, the oenological abilities of wine yeasts can be preserved over long periods of maintenance under laboratory conditions.

Cím:Density-dependent plant-plant interactions triggered by grazing / András Kelemen, Csaba Tölgyesi, Orsolya Valkó, Balázs Deák, Tamás Miglécz, Réka Fekete, Nóra Balogh, Péter Török, Béla Tóthmérész
Dátum:2019

Megjegyzések:Plant species performance in rangelands highly depends on the effect of grazing and also on the occurrence of unpalatable benefactor species that can act as biotic refuges protecting neighboring plants from herbivores. The balance between facilitation and competition may changes with the benefactor density. Despite the high number of studies on the role of biotic refuges, the density dependent effects of unpalatable herbaceous plants on the performance of other species, and on the habitat heterogeneity of rangelands are still unclear. Therefore, we performed a study to test the following hypotheses: (i) Performances of understory species follow a humped-back relationship along the density gradient of the unpalatable benefactor species. (ii) Small-scale heterogeneity of the vegetation decreases with increasing benefactor density. We studied meadow steppes with medium intensity cattle grazing in Hungary. We surveyed understory species' performance (number of flowering shoots and cover scores) along the density gradient of a common, native unpalatable species (Althaea officinalis). Our findings supported both hypotheses. We found unimodal relationship between the benefactor cover and both the flowering success and richness of understory species. Moreover, small-scale heterogeneity declined with increasing benefactor cover. In this study we detected a humped-back pattern of facilitation along the density gradient of an herbaceous benefactor in pastures. Indeed, this pattern was predictable based on such conceptual models like ?consumer pressure-abiotic stress model', ?humped-back model', ?intermediate disturbance hypothesis' and ?disturbance heterogeneity model'; but until now the validity of these relationships has not been demonstrated for herbaceous species. By the demonstration of this effect between herbaceous species we can better forecast the responses of grasslands to changes in management.

Megjegyzések:We tested the establishment success of grassland species in the presence or absence of zoochory by livestock and identified the traits associated with successful establishment. Hortobágy National Park, Hungary. In six restored species-poor grasslands we established two species-rich 4 m ? 4 m source plots per site in 2013. One source plot was managed by extensive cattle grazing ("zoochory on"), the other one was fenced and protected from grazers ("zoochory off"). We monitored the vegetation development in the source plots (2014?2018), and the establishment success of sown species (2016?2018) in adjacent dispersal plots in four, 20-m-long strips per source plot in a total of 960 dispersal plots. We calculated community-weighted means of thirteen plant traits related to regeneration and competitive ability. The effect of grazing, year, distance from source plots, grazing?year and grazing?distance interactions on population and trait dynamics in the source and dispersal plots were analysed with generalized linear mixed-effect models. Although grazing reduced the cover and flowering success of sown species in the source plots, the number of successful establishment events was higher in dispersal plots next to grazed source plots. The sown species were the most abundant in plots adjacent to source plots, but occurred at all monitored distances. Zoochory favoured perennial plants with high specific leaf area (SLA), low leaf dry matter content (LDMC), short stature, light seeds, early flowering period, high clonal index and anemochory index. We showed that species that can colonize the matrix with and without zoochory have contrasting trait syndromes. In grazing-adapted ecosystems, fencing source populations of target species does not always seem to be a good option. It was a good tool for increasing the cover and flowering success of the sown species in the short run, but it significantly decreased their chance to colonize the surrounding area in the long run.

Cím:Predominant female care in the beetle Lethrus apterus with supposedly biparental care / András Kosztolányi, Nikoletta Nagy, Tibor Kovács, Zoltán Barta
Dátum:2015
ISSN:1343-8786 1479-8298
Megjegyzések:Although intensive care for offspring by both parents is rare in arthropods, it occurs in some species including the beetle Lethrus apterus. According to previous publications, in this species the male collects leaves, which are used by the female to form balls in the underground nest burrow. These balls serve as food for the hatched offspring. Most knowledge about the behavior of this species is based on information collected more than a century ago. Therefore, we investigated above-ground breeding behavior and the status of nest burrows of this beetle in its natural habitat in Hungary. Our results suggest that contrary to previously documented cases, above-ground parental care, i.e. the collection of leaves, is done predominantly not by the males but the females. Further research is needed to understand the role of the sexes in parental care in this species and to explain the discrepancy between the previously documented cases and the results we report here.

Cím:Testing the efficiency of extraction of incurred residues from soil with optimized multi-residue method / Gabriella K. Suszter, Árpád Ambrus
Dátum:2017
ISSN:0360-1234
Megjegyzések:The reproducibility of extraction of residues from spiked soil samples and from soils containing incurredresidues was tested with 14C-labeled test compounds of different physical-chemical properties. Nearly100% of the compounds added to the sample before extraction could be recovered with an averagereproducibility relative standard deviation (CV) of 5.4%. The additional steps of the determination process(cleanup, evaporation, etc.) contributed to the major part of the variability of the results (CV D 10-20%).The incurred residues were most efficiently extracted with acetone for 30 min followed by the mixture ofacetone/ethyl acetate 1:1 for additional 30 min. However, they could only be recovered at various extent(64-90% of total residues), underlying the importance of testing the efficiency of extraction. The residueswere identified and quantified by gas chromatography applying thermionic detector. The performanceparameters of the method complied with the international method validation guidelines, and they provedto be robust and suitable for determination of pesticide residues in soils of widely different physical?chemical properties.
