Popis: Extensive biodiversity conservation efforts in Europe resulted in the recent establishment of the ecological network of protected areas Natura 2000. However, it remains unclear how such protected areas reflect the distribution of soil biodiversity, which represents a substantial fraction of terrestrial biodiversity and drives a plethora of ecosystem services. Here we analyzed and compared different metrics of soil nematode taxonomic diversity, i.e., taxon richness, Shannon Diversity Index, Shannon Evenness (all based on supraspecific diversity), and functional diversity, i.e., Maturity Index (environmental disturbance), Structure Index (food web complexity), Enrichment Index (system enrichment), and Channel Index (dominant decomposition pathway of soil organic matter) in 16 grasslands assigned to two Natura 2000 priority habitat types and 14 grasslands assigned to five Natura 2000 non-priority habitat types in Romania. Nematode communities consisted of a total of 123 taxa (115 genera and 8 suprageneric taxa). We found no significant difference in nematode taxonomic and functional diversity between grasslands assigned to Natura 2000 priority and non-priority habitats, suggesting that this categorization does not reflect nematode diversity patterns.
