Descripción
The dataset presents the results of a long-term monitoring program for arachnids (Aranei and Opiliones) that inhabit 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 were sampled in industrially undisturbed areas and could be used as a local reference. The dataset describes the 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 were collected using biocenometer (3 sampling plots (=locationID) in total), inhabitants of forest litter were collected using line-designed (8 plots) and matrix-designed pitfall trapping (1 plot). The dataset includes 1351 samples (=sampling events), which corresponded to 5462 occurrences (identifications mainly to species) identifie during 2004–2009, 2013 and 2018. Only samples that contained arachnids (occurrenceStatus=present) have been provided.

Cobertura geográfica
The studied areas are located in the southern taiga zone of the Central and Southern Urals. The polygon at the Central Urals is located 60–70 km westbound from Yekaterinburg in primary spruce-fir and secondary aspen-birch forests with secondary upland meadows created through clear-cutting. At the Southern Urals two polygons are located in 10 and 60 km NE from Miass, in pine-birch forest.

Métodos de muestreo
1. Sampling of meadow grass stand invertebrates with biocenometer was carried out no closer than 10 m from the forest edge. The points for installing the biocenometer were chosen randomly but at intervals of no less than 5 m. The sampling procedure was carried out from 9:00 to 21:00 local time. The sampling plots were examined on the same day. Morning-, midday-, and evening-time-collected samples were available for each investigated plot. Sampling was timed to the second half of every summer month (10 samples per plot) from 2006 to 2008. 2. Sampling of forest litter invertebrates was conducted with two general schemes. Line-designed scheme includes 5 pitfall traps per trapping line, with a spacing of 3 m, and 3 lines per sampling plot (a total of 8 plots). Matrix-designed scheme includes 7×7 matrix of pitfall traps with 10 m spacing on a single sampling plot. Locations of every trap were permanent throughout the study. Traps were emptied once per 3 to 6 days. Sampling was conducted in two-time sets – May–June and August–September (which is timed to the peak abundance of spring-summer and summer-autumn species) in 2004, 2009 and 2013 (for line-designed trapping) and in 2005 and 2018 (for matrix-designed trapping).
| Área de Estudio | The study was conducted in the southern taiga zone of the Central and Southern Urals, Russia, in the lowest part of uplands (300–400 m altitude above sea level). A total of twelve sampling plots (=locationID) were established across three types of biotopes: primary spruce-fir (4 plots), secondary aspen-birch forests (2 plots), pine-birch forest (3 plots), and secondary upland meadows (3 plots). All the represented schemes are ongoing long-term monitoring projects. At the present time, the following periods are covered: May, 12, 2004 – September, 08, 2009; June, 14, 2013 – September, 02, 2013; May, 24, 2018 – August, 21, 2018. |

| Control de Calidad | All collected specimens of arachnids (more then 10 400) are wet-preserved in 70% alcohol and stored in the depository of the Laboratory for Population and Community Ecotoxicology of IPAE UB RAS. Most of the adult specimens were identified to species (except for the ones severely damaged during the sampling). Species identification was also carried out on juvenile specimens in cases where there were no doubts. Identification of species throughout the entire period was performed by the permanent team of researchers (IPAE UB RAS) and cross-checked by the specialists from the Department of Zoology of Perm State University. All determinations that appear controversial are welcome to be discussed upon request. Taxonomic nomenclature has been verified for spiders using World Spider Catalog (2020); for harvestmen using (Jong et al., 2014) and the local catalogue of Ural’s fauna (Farzalieva, Esyunin, 1999). |
Descripción de la metodología paso a paso:
- 1. Sampling of grass stand invertebrates was carried out at 3 permanent free-form sampling plots (approximately 2500 m² in size) that were positioned at a distance of 100–300 m from each other in the lower parts of the secondary upland meadows created through forest clear-cutting more than 60 years ago. Sampling was timed to the second half of every summer month from 2006 to 2008. Sampling was performed by using a modified biocenometer consisting of a bottom (metal frame 50×50 cm) hermetically connected to a cube-shaped covering of a dense cloth. One of the lateral sides of covering was sewn from nylon gauze (mesh diameter 0.25 mm) and used as a light screen to attract invertebrates with positive photokinesis. The opposite-to-screen side of covering contains an aperture with an inlet valve for the researcher. Invertebrates were collected with a suction sampler from a light screen and inner surfaces of biocenometer until the new targets stopped appearing. All the plants that got inside were also processed with a suction sampler (to gather invertebrates), cut with scissors at ground level and taken away for a manual check for hidden invertebrates. Then the biocenometer was turned over and its inner surface and seams were examined, as well as the soil surface and bases of plant stems. All detected invertebrates were devitalized by ethyl acetate and preserved in 70% alcohol. The sampling procedure was carried out from 9:00 to 21:00 local time. All three sampling plots were examined on the same day. Morning-, midday-, and evening-time-collected samples were available for each investigated plot. The points for installing the biocenometer were chosen randomly but at intervals of no less than 5 m. 10 samples per plot were taken in each summer month.
- 2. Pitfall trapping was carried out in biotopes most typical for the studied areas: primary spruce-fir forest, secondary aspen-birch forest and pine-birch forest. Sampling plots were founded in sites with the lowest degree of degradation of woody vegetation. Barber’s traps were used (plastic glasses, diameter 8.5 cm, 3% acetic acid solution as a fixative) in line–designed and matrix–designed schemes. Line-designed scheme (5 traps per line with 3 m spacing between traps, 3 lines per sampling plot no closer than 100 m from each other, 8 plots (each approximately 2400 m² in size) in total were examined both in spruce-fir (3 plots) and aspen-birch (5 plots) forests; matrix-designed (7×7 matrix of traps with 10 m spacing) on a single square-form sampling plot (3 600 m²) in a spruce-fir forest. All plots and locations of every trap were permanent throughout the study. Sampling was conducted in two-time sets – May–June and August– September (which is timed to the peak abundance of spring-summer and summer-autumn species) in 2004, 2009 and 2013 (for line-designed trapping) and in 2005 and 2018 (for matrix-designed trapping). The traps were emptied once per 3 to 6 days; all collected invertebrates were preserved in 70% alcohol.
- 3. Identification was carried out in laboratory using (Nentwig et al., 2019) for spiders, and identification keys of (Farzalieva, Esyunin, 1999) for harvestmen, as well as some additional monographs.
