Abstract

Using one of the Kuzbass coal mines as an example, it is shown that Lycosidae is the most important group of spiders that settles in reclaimed dumps at the early stages of overgrowing. The most commonand widespread wolf spiders on the dumps are Alopecosa accentuata, Alopecosa cuneata, and Xerolycosa miniata. The maximum of species diversity and dynamic density was discovered on the slope of the 15-yearolddump, where 14 species of Lycosidae were observed, and the dynamicdensity reached almost 300 specimens per 100 trap-days. The greatest number of the family Lycosidae spiders’ species occurred on the different aged slopes of dumps at the end of June, while on the terraces - in the firsthalf of June. The highest dynamic density of wolf spiders on the slopes and terraces of the reclaimed dumps has been registered in the second half of June. It was close to 300 specimens per 100 trap-days on the slope of the15-year-old dump. This parameter was more stable and had a bigger valueat the control area in early August than on the slopes and terraces of the dumps.

Highlights

Kuznetsk coal basin (Kuzbass) is one of the world’s largest coalfields
Wolf spiders on the first site (Fig. 1), that is located on the slope of a 15year-old dump, were the most taxonomically varied and numerous

Summary

Introduction

Kuznetsk coal basin (Kuzbass) is one of the world’s largest coalfields. The coal basin is located mainly in the central part of the Kemerovo region between the mountain provinces of the Kuznetsk-Salair mountainous region: Kuznetsky Alatau in the east, Gornaya Shoria in the south and Salair Ridge in the west. Due to the open (career) method of minerals excavating, considerable areas have been occupied by coal dumps, which are extreme examples of natural ecosystems and landscapes transformation. Problems of recovering processes’ research and research of the various stages' features of succession at the coal mining sites are becoming increasingly urgent in the region. One of the most important branches of this research is the study of the technogenic factors’ influence on faunal complexes and the population of various groups of invertebrates which could indicate a state of both natural and artificially transformed ecosystems [1-3]
