Arachnids (Aranei, Opiliones) from grass stand and forest litter in the Urals, Russia
The dataset presents the results of a long-term monitoring program for arachnids (Aranei and Opiliones) that habit meadow grass stand and forest litter in the Central and Southern Urals. The monitoring was carried out using permanent plots located in spruce-fir and aspen-birch forests and secondary dry meadows. All represented data was sampled in industrially undisturbed areas and could be used as a local reference. The dataset describes quantitative and qualitative structure of arachnids, age-sex composition, seasonal and inter-annual dynamics. Arachnids were sampled with three general schemes: inhabitants of grass stand using biocenometer (3 sampling plots (=locationID) in total), inhabitants of forest litter using line-designed (8 plots) and matrix-designed pitfall trapping (1 plot). The dataset includes 1351 samples (=sampling events), corresponded to 5463 occurrences (identifications mainly to species) made during 2004–2009, 2013 and 2018. Only samples contained arachnids (occurrenceStatus=present) are provided.
