Cím:	Dragonfly assemblages of a shallow lake type reservoir (Tisza-tó, Hungary) and its surroundings / Jakab T., Müller Z., Dévai G., Tóthmérész B.

Megjegyzések:	The dragonfly fauna of the typical water bodies of the Reservoir Tisza-tó was characterised based on a two-year study. We collected 728 imagoes, 384 larvae and 194 exuviae during the study, and there were 101 observations of imagos. We confirmed the presence of 39 species (13 Zygoptera and 26 Anisoptera). We distinguished 5 types of water bodies inside and around the Reservoir Tisza-tó: leaking canals, a new inundated area of the reservoir, native water bodies inside the reservoir, in- and outflows, and River Tisza inside the reservoir. Both traditional diversity statistics and scalable diversity characterisation suggested that the most species-rich were the native water bodies, with a species-pool of 34 species; there were 30 species in the in- and outflows, while the leaking canals and the reservoir were moderately species-rich with 25 species each. The River Tisza was relatively species-poor compared to the other water bodies (12 species). Cluster analysis of the species composition revealed that the fauna of the River Tisza is clearly separated from the other water bodies. The fauna of the new inundated area, the native water bodies, and the in- and outflows were similar; these water bodies had direct connection to the reservoir. The fauna of the leaking canals was slightly different from them.

Cím:	Environmental-friendly Contamination Assessment of Habitats Based on the Trace Element Content of Dragonfly Exuviae / Edina Simon, Béla Tóthmérész, Olga Kis, Tibor Jakab, Petra Éva Szalay, András Vincze, Edina Baranyai, Sándor Harangi, Margit Miskolczi, György Dévai

Megjegyzések:	We tested the usefulness of exuviae as an environmentally friendly method for exploring the variability of the trace element contents of protected insect populations without killing specimens. It is a notable characteristic of dragonflies that they are good ecological indicators for both aquatic and terrestrial habitat quality. Thus, we investigated the trace element accumulation in different stages of dragonflies: larva, exuvia, and adult. Using microwave plasma atomic emission spectrometry (MP-AES), we analysed the concentrations of Al, Ba, Cr, Cu, Fe, Mn, Pb, Sr and Zn. We found that the trace element contents of exuviae are a good proxy of the trace element contents of both the larvae and the adults. We conclude that exuvia is useful for assessing the environmental health of aquatic ecosystems. It is an environmentally friendly method and it can be used even in the case of protected dragonfly species.

Cím:	Assessment of contamination based on trace element concentrations in Gomphus flavipes (Odonata: Insect) larvae of the Upper Tisza Region / Simon E., Kis O., Jakab T., Kolozsvári I., Málnás K., Harangi S., Baranyai E., Miskolczi M., Tóthmérész B., Dévai Gy.

Megjegyzések:	Odonata larvae are frequently used to assess the contamination of aquatic systems, because they tolerate a wide range of chemical and biological conditions in freshwater systems. In early 2000, the sediments of the Hungarian section of the River Tisza and the River Szamos were strongly enriched with heavy metals by an accidental mining spill. Earlier studies demonstrated higher contamination levels in the Szamos than in the Tisza, based on sediment analysis. The aim of our study was to assess the contamination in the Upper Tisza Region, along the upper reach of the Tisza, and the lower reach of the Szamos, based on the trace element concentrations of the Gomphus flavipes larvae. We collected 269 dragonfly specimens for the analyses. The Al, Ba, Cr, Cu, Fe, Mn, Pb, Sr and Zn element contents were analysed in the dragonfly larvae by microwave plasma atomic emission spectrometry (MP-AES). Significantly higher Ba and Cu concentrations were found in the dragonfly larvae of the Tisza than the Szamos. In spite of this, the Cr, Mn, Pb, Sr and Zn concentration was significantly lower in the dragonfly larvae of the Tisza than the Szamos. For all trace elements significant differences were found along the Tisza. Significant differences were also found in all trace element concentrations of dragonfly larvae among studied localities in the Szamos, except in the cases of Al and Ba. Our results demonstrated that the Szamos was more contaminated with Cr, Mn, Pb, Sr and Zn than the Tisza, but that the Tisza was more contaminated with Ba and Cu than the Szamos, based on the trace element concentrations in Gomphus flavipes larvae, which was likely to have been caused by the tributaries of the Tisza. In summary, our results indicated a continuous pollution of the Tisza and the Szamos and their tributaries.
