“…Due to their diverse communities they significantly influence ecosystem processes, particularly in soil (Vinciguerra, 1979;Wasilewska, 1979;Bongers & Bongers, 1998), and they are a useful indicator of soil condition in forest ecosystems (Yeates, 2007). The fauna of soil nematodes in forest ecosystems of Slova-... kia was relatively well studied (Šály, 1983;Lišková et al, 2008;Čerevková & Renčo, 2009), but the eastern woodland of the Vihorlat mountains has not been paid attention till now.…”

SummaryFauna of soil nematodes was studied in three main forest types of the Vihorlat Mountains, Querceto-Fageto-Aceretum at Remetské Hámre (RH), Fagetum at Morské oko (MO), and Fageto-Aceretum at Sninský kameň (SK). Each forest type was represented by five sites. In total 198 species and 98 genera of soil nematodes were distinguished. Most species belonged to rare taxa with the frequency of occurrence lower than 50 %. The number of species and genera decreased from RH (167 species and 86 genera) through MO (115 and 68) to SK (87 and 51). Species and generic richness was significantly positively correlated with soil pH(H 2 O), negatively with altitude, soil moisture and C ox . Greater part of nematode species and genera belonged to microbivores and to the taxa with higher cp values of 3 -5. We can conclude that rich nematode fauna indicated undisturbed forest soil condition, nevertheless, the richness decreased with increasing altitude.

“…In most of the cases, however, ZnO NPs with smaller particle size were more toxic (Ma et al 2011 , Khare et al 2011 ). Free-living soil nematodes are part of the food chain, are involved in degradation and remediation processes and have great importance in the global biogeochemical cycles of various substances (Vinciguerra 1979 , Sochová et al 2006 ). Therefore, it is crucial to investigate the effects on soil nematodes exposed directly to ZnO NPs, preferably in the most environmentally relevant test medium.…”

To better understand the nanosize-relevant toxic effects and underlying mechanisms, N-acetylcysteine (NAC), as a mitigation agent, an ionic form of Zn (ZnCl2), and the binary mixture of ZnO with different particle sizes (15 nm and 140 nm), was used in toxicity assays with the nematode Panagrellus redivivus. The ZnCl2 concentrations were applied to show the amount of dissolved Zn ions present in the test system. Reactive oxygen species (ROS) measuring method was developed to fit the used test system. Our studies have shown that NAC can mitigate the toxic effects of both studied particle sizes. In the applied concentrations, ZnCl2 was less toxic than both of the ZnO particles. This finding indicates that not only ions and ROS produced by the dissolution are behind the toxic effects of the ZnO NPs, but also other particle size-dependent toxic effects, like the spontaneous ROS generation, are also relevant. When the two materials were applied in binary mixtures, the toxic effects increased significantly, and the dissolved zinc content and the ROS generation also increased. It is assumed that the chemical and physical properties of the materials have been mutually reinforcing to form a more reactive mixture that is more toxic to the P. redivivus test organism. Our findings demonstrate the importance of using mitigation agent and mixtures to evaluate the size-dependent toxicity of the ZnO. Graphical abstract
