Cím:	Past and present: changes in the Odonata fauna of small lowland watercourses / Kálmán Szanyi, István Grigorszky, László J. Szabó, György Dévai

Megjegyzések:	Small lowland watercourses, strongly exposed to anthropogenic activities and climate change, have received negligible odonatological attention. This study provides a revised checklist of three typical lowland small watercourses (Kállai-főfolyás, Konyári-Kálló and Ölyvös) within the Pannonian Lowland and presents the changes in their diversity over the past decades. Results revealed a significant biodiversity loss, with a 31.6% decline in Odonata fauna over the last 53 years. The upper and middle sections degraded the most, where the habitats have dried out or become intermittent. However, a diverse Odonata assemblage (1,277 individuals of 27 species) was observed at the 14 sampling sites of the three watercourses, containing protected and sensitive species (Somatochlora flavomaculata, Orthetrum brunneum, Aeshna isoceles, Libellula fulva). However, the low abundance of larval and exuvial forms (59 individuals of 13 species) suggests that the majority of the observed adults were developed in other watercourses. While recolonisation from nearby habitats is still possible, a parallel degradation of adjecent waterbodies could lead to an irreversible biodiversity loss.

Cím:	Caddisfly (Trichoptera, Insecta) fauna and assemblages of the north-eastern part of the Pannonian Lowland (West Ukraine, Transcarpathia) / Szanyi Kálmán, Nagy Antal, Szanyi Szabolcs
Dátum:	2022
ISSN:	1314-2836 1314-2828
Megjegyzések:	The caddisfly fauna of the Transcarpathian part of the Pannonian Lowland was poorly studied formerly. Here, we present the results of a six-year survey (2015-2020) carried out in four sampling sites of the Ukrainian part of the Bereg Plain and provide the actualised checklist of this area. Actually, 7346 specimens of 53 caddisfly species were collected. The number of known caddisfly species increased from 13 to 61. Two species Hydropsyche guttata and Parasetodes respersellus, which formerly were considered extinct in the Pannonian Ecoregion, were detected and another especially rare species (e.g. Cyrnus flavidus) was also recorded. The fauna of the region cover a significant part of both Hungarian and Ukrainian caddisfly fauna. Assemblages of four characteristic habitat types of the region showed significant differences considering their quantitative and qualitative composition, substrate, current, hydrological- and feeding types. The high diversity and natural value of the small lowland watercourses were proven using a new Caddisfly Conservation Index (CCI) calculated, based on vulnerability and rarity of species. The fauna and assemblages showed a unique character mainly independent from large rivers of the region.
