We report the first record of Opilio saxatilis C. L. Koch, 1839 (Arachnida, Opiliones, Phalangiidae) from Serbia. The species was observed in the alluvium of the Tisa River in the Special Nature Reserve Ritovi donjeg Potisja.
Wetlands and especially floodplain forests belong to the most endangered ecosystems in Europe, characterized by complex dynamics of flood and dry periods and providing specific irreplaceable habitats for many organisms, including bioindicators. Many rove beetle species, for instance, are well-known detectors in monitoring ecological change, however, their use in environmental assessment requires to expand the insufficient knowledge on ecological environmental particularities of their assemblages. Therefore, we compared the rove beetle communities in eight habitats of floodplain forests from 2015 to 2016. Staphylinids were sampled by pitfall trapping. We compared the rove beetle taxocoenoses in the floodplain forests and their ecotones alongside three rivers (Danube, Tisa and Begej). We evaluated the impact of plant diversity and cover of vegetation layers, area, circumference and age of forest stands, distance to the forest edge, thickness of the litter layer, physical and chemical properties of soil and leaf litter (conductivity, pH, P, N, H, C) and anthropogenic impact on structure of rove beetle communities. We recorded significant interactions between total dynamic activity of rove beetles and number of plant species in shrub vegetation layer. Species richness was significantly positively correlated with number of plant species in shrub vegetation layer and soil pH, and negatively with relative H content of soil. We did not find any significant correlation between Shannon diversity, but evenness was negatively linked with species richness of plant communities in shrub layer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
