Cím:	The effects of micro-habitats and grazing intensity on the vegetation of burial mounds in the Kazakh steppes / Deák Balázs, Tölgyesi Csaba, Kelemen András, Bátori Zoltán, Gallé Róbert, Tatyana M. Bragina, Abil I. Yerkin, Valkó Orsolya

Megjegyzések:	Background: Burial mounds (kurgans) of Eurasian steppes are man-made habitat islands that have the potential to harbour rich plant diversity due to micro-habitats associated with their topography. Aims: We assessed whether kurgan micro-habitats harboured different species pools and functional groups from those found on the surrounding steppes. In addition, we asked if these mounds were affected by different grazing intensities from those on the surrounding vegetation. Methods: We surveyed kurgan micro-habitats (northern and southern slopes, surrounding ditch) and adjacent steppe plains in non-grazed, moderately grazed and heavily grazed sites in northern Kazakhstan. We analysed differences in species composition of four habitats under three grazing regimes using Generalised Linear Mixed Models, PCA ordination and indicator species analysis. Results: Kurgan micro-habitats had diverse vegetation and supported the co-existence of plant species with different environmental needs. We identified 16 steppe specialists confined to kurgan micro-habitats. Steppe vegetation was welladapted to extensive grazing, although heavy grazing supported ruderals and a decline in steppe specialists. There was a significant interaction between grazing intensity and habitat type: heavy grazing supported ruderals and suppressed steppe specialists especially on the slopes. Conclusions: We highlighted that kurgans play an important role as maintaining high plant diversity locally in extensive steppe plains in Central-Asia by increasing environmental heterogeneity and supporting specialist species confined to these micro-habitats.

Cím:	Species and functional diversity of arthropod assemblages (Araneae, Carabidae, Heteroptera and Orthoptera) in grazed and mown salt grasslands / Attila Torma, Péter Császár, Miklós Bozsó, Balázs Deák, Orsolya Valkó, Orsolya Kiss, Róbert Gallé

Megjegyzések:	Grazing and mowing are widely applied management practices in semi-natural grasslands, which are one of the most important habitats for biodiversity conservation in Europe. Due to the decline in extensively grazing livestock numbers, an increasing area of formerly grazed grasslands has being used as mown grasslands. However, we have scarce information on how arthropod assemblages are influenced by mowing in formerly grazed pastures. We assessed the effects of mowing compared to grazing on the species richness, abundance and functional diversity of arthropods in three grassland complexes in Hungary. Since 2005, these salt grasslands have been divided into two management units: extensive grazing management has been continued in one part, while annual late cutting has been established in the other part. In each management unit five sites were sampled. Spiders and ground beetles were sampled using pitfall traps, orthopterans and true bugs were sampled using sweep nets twice before cutting in 2015. In total, the data relating to 12,576 adult individuals of 334 species were analysed using mixed-models. Plant-dwelling true bugs and orthopterans responded more sensitively to mowing than ground-dwelling spiders and ground beetles. Beside the general negative effect of mowing on the species richness and abundance of plant-dwelling arthropods, the shifts in the community weighted mean values of these assemblages suggested the importance of the body size, trophic behaviour and dispersal ability of species in the functional response of these assemblages to the different management regimes. Ground beetles and spiders were rather influenced by the differences in the moisture conditions and vegetation properties. Presumably, strong abiotic stressors such as drought can partly override management effects on ground-dwelling arthropods. The effect of uniform and simultaneous biomass removal on large areas, and the direct mortality caused by mowing was the most disadvantageous for plant-dwelling arthropods. Based on our results, traditional management practices should be prioritized in grassland conservation, as alternative management practices might be less effective in preserving grassland biodiversity.
