Methods

In this data set, only 0.01sqm samples were used. We built our database by compiling sampling events of soil invertebrates, based on an exhaustive search in published and unpublished authors' sources, as well as from the Zoological Museum of the Institute of Biology Komi SC UB RAS. The data paper is based on three datasets. The datasets about macrofauna and collembolans provides temporal data on the number of their individuals in soil cores collected in pine and spruce forests of the production area of the pulp and paper industry enterprise. The dataset about macrofauna also contains the material collected by the pitfall traps and information on the age stages (larvae and imago) of invertebrates. Nematodes were collected in pine and spruce forests of the production area of Mondi Syktyvkar JSC only in 2018-2019, so these data are not temporal. The dataset about Nematoda provides information on the number of their individuals in soil cores. Three datasets have differences in data presentation. We have combined them into one data paper, since a comprehensive study of the effect on soil invertebrates from the pulp and paper industry has not previously been carried out. Sampling description: The standard methods of soil zoology were applied. Sampling and pitfall trapping were carried out in pine and spruce forests of the impact, buffer and background zones of the enterprise production area. Two sampling methods were used for collection of macrofauna at each site. 1. Soil sampling method. About 8-10 soil cores were randomly taken to a depth of 5-10 cm at each site. A quadrangular frame of 25 × 25 cm or 10 × 10 cm was used for sampling. Actively moving animals were placed into containers with 70% alcohol as a fixative. Further, in laboratory conditions, the extraction of invertebrates from soil cores into 70% alcohol was carried out in the funnels. One sampling method was used for Collembola collection. In each site, 10 soil samples were taken. Samples were taken to the full depth with division into two layers - litter and mineral horizons; in further analysis, the data on the layers were combined. Extraction was carried out according to the generally- accepted method using Berlese Tulgren funnels in 96% alcohol for 710 days - the time sufficient to achieve an air-dry soil state. Collembolans from the samples were sorted under a binocular microscope. All individuals were mounted in slides in Phoera liquid according to a standard procedure (Potapov and Kuznetsova 2011).
