The list of taxa of large soil invertebrates and microarthropods (with their abundance) collected in the deciduous forests after clear cutting is presented in Table. The research was carried out in two plots which located in the middle taiga zone of Komi Republic (near Syktyvkar city), european part of Russia. Plot 1 is a 25-year-old birch-spruce forest of a forb type. Plot 2 is a 54-year-old aspen-birch forest of a blueberry-forb type. Despite similar soil conditions and the original type of spruce forest, the plots differ the stock of forest litter. The litter capacity is 46.1 ± 19.3 t / ha in the birch-spruce forest. This parameter is only 40.0 ± 11.6 t / ha in the aspen-birch forest. The soil sampling method was chosen for collecting of invertebrates. As a result, 16 taxa of soil invertebrates were revealed In the birch-spruce forest. Oribatida and Collembola were abundant groups among mesofauna, Diptera was a dominant group among macrofauna. The same taxa, with the exception of Dytiscidae and Thysanoptera, were identified in the aspen-birch forest, as well as two more taxa Cantharidae and Psocoptera, which are not found in the first plot.


Steps to reproduce

25 soil samples of size 10x10 cm at a depth of an organogenic horizon of 4–7 cm were taken at a distance of 2 m from each other at each plot in July 2020. Soil invertebrates were distilled on eclectors in laboratory conditions. The animals were fixed in 95% alcohol. The microarthropods and large soil invertebrates were identified at taxa level and accounted. Statistical processing of the results was carried out using computer data processing in Microsoft Office Excel and PAST. A total of 50 soil samples were collected, 53402 specimens of soil invertebrates adults and larvae were extracted, including 41610 specimens of mites and 10584 specimens of collembolans.
