Cím:Cladocera remains and vegetation types to assess the state of oxbows / István Gyulai, Csilla Lakatos, János Tamás Kundrát, Zsuzsanna Balogh, Edina Simon, Béla Tóthmérész
Dátum:2018
ISSN:1314-6947 1314-3301
Megjegyzések:AbstractWe assessed the usefulness of Cladocera remains for establishing the ecological status of oxbows and also tested the association of Cladocera species with various vegetation types. Cladocera remains were collected from the surface sediment of four habitat types (tangled vegetation, open water, reeds and tunnels) and 15 physical and chemical parameters of surface water were studied. In the surface sediment samples, we identified 32 Cladocera taxa. There was a significant difference in the number of species amongst habitat types as per ANOVA. The benthic and plant associated Cladocera communities of reeds, tangled vegetation, open water and tunnels were clearly separated from each other by NMDS ordination. CCA showed that habitat types had characteristic Cladocera species: Pleuroxus species were frequent in the tangled vegetation habitat, while Chydorus species were frequent in the open water. Remarkably, in reeds, Bosmina species were frequent, although these species are usually common in open water. Specimens of the Alona genus were found everywhere. Our findings suggest that the remains of Cladocera species may be useful indicators to assess and monitor the structure of freshwater lakes.

Cím:Remediation potential of early successional pioneer species Chenopodium album and Tripleurospermum inodorum / Tőzsér Dávid, Tóthmérész Béla, Harangi Sándor, Baranyai Edina, Lakatos Gyula, Fülöp Zoltán, Simon Edina

Megjegyzések:Remediation with plants is a technology used to decrease soil or water contamination. In this study we assessed the remediation potential of two weed species (Chenopodium album and Tripleurospermum inodorum) in a moderately metal-contaminated area. Metal concentrations were studied in roots, stems and leaves, in order to assess correlations in metal concentrations between those in soil and plants. Furthermore, we calculated bioaccumulation factor (BAF), bioconcentration factor (BCF) and translocation factor (TF) values to study the accumulation of metals from soil to plants and translocation within plants. We found correlation in metal concentrations between soil and plants. The metal accumulation potential was low in both species, indicating low BAF and BCF values. In contrast, high TF values were found for Mn, Ni, Sr, Zn, Ba, Fe, Cu and Pb in C. album, and for Fe, Mn, Ni, Zn and Sr in T. inodorum. Our results demonstrated that the potential of C. album and T. inodorum might be limited in phytoextraction processes; however, when accumulated, metals are successfully transported to aboveground plant organs. Thus, to achieve the efficient remediation of metal-contaminated soils, removal of the aboveground plant organs is recommended, by which soil disturbance can also be avoided.

Cím:Cultural heritage and biodiversity conservation - plant introduction and practical restoration on ancient burial mounds / Valkó Orsolya, Tóth Katalin, Kelemen András, Miglécz Tamás, Radócz Szilvia, Sonkoly Judit, Tóthmérész Béla, Török Péter, Deák Balázs

Megjegyzések:Linking the conservation of cultural heritage and natural values provides a unique opportunity for preserving traditional landscapes and receives an increased awareness from stakeholders and society. Ancientburial mounds are proper objects of such projects as they are iconic landscape elements of the Eurasiansteppes and often act as refugia for grassland specialist species. The aim of this project was to reintroducegrassland plant species to burial mounds for representing them as cultural monuments with the associatedbiodiversity for the public. The effectiveness of seed sowing, transplanting greenhouse-grown plantsand individuals from threatened populations on burial mounds in Hortobágy National Park, Hungarywas tested. The following questions were answered: (1) which method is the most effective for speciesintroduction? (2) which species can establish most successfully? (3) how does management affect thespecies establishment rates? It was found advisable to use a combination of seed sowing and transplantinggreenhouse-grown plants. Sowing was found as a cost-effective method for introducing large-seededspecies, whilst introduction of greenhouse-grown transplants warranted higher establishment rates for alarger set of species. Transplanting adult individuals was more reliable regardless of management regimes,however this method is labour-intensive and expensive. Intensive management, like mowing with heavymachinery and intensive grazing, should be avoided in the first few years after introduction. The authors highlighted the fact that introducing characteristic grassland species on cultural monuments offers a greatopportunity to link issues of landscape and biodiversity conservation. This project demonstrated that, bythe revitalisation of cultural monuments, cultural ecosystem services can also be restored.
