Impact of Environmental Conditions on Bottom Oligochaete Communities in Subsidence Ponds (The Silesian Upland, Southern Poland)

Abstract

The aim of the study was to estimate the influence of environmental conditions resulting from coal mining on the diversity of bottom oligochaete communities in subsidence ponds. In the ponds studied 17 oligochaete species representing the families Lumbriculidae (1 species), Enchytraeidae (1 species) and Naididae (15 species), in the new sense (ERSÉUS et al., 2008) were collected. The presence of Aulodrilus japonicus YAMAGUCHI, 1953 and Potamothrix bavaricus (OSCHMANN, 1913), rare species in anthropogenic water bodies, is noteworthy. Canonical correspondence analysis (CCA) showed that the important factors influencing oligochaete distribution in the subsidence ponds studied were the type of substratum, the organic matter content of the sediment as well as the mineralization of the water.

The impact of environmental factors on the diversity of gastropod communities in sinkhole ponds in a coal mining region (Silesian Upland, Southern Poland)

“…Our studies established a preference for a coal shale bottom with silt for Chironomidae, Caenidae and primarily Naididae, among which these species were ubiquitous (Krodkiewska & Królczyk 2012). Previous studies documented the impact of bottom sediments on the occurrence and diversity of gastropods (Strzelec 1993;Chertoprud & Udalov 1996;Collier et al 1998).…”

“…Previously, the occurrence of 18 gastropod species (Strzelec & Serafiński 2004), 9 leech species (Krodkiewska 2003) and 23 oligochaete species (Dumnicka & Krodkiewska 2003;Krodkiewska 2006;Krodkiewska & Królczyk 2012) has been demonstrated in these reservoirs, which are often defined as hydrological wastelands. These ponds are often valuable refuges for rare or vulnerable plant and animal species and act as the recipient area for alien species and invasive species among others (Lewin & Smoliński 2006;Strzelec 2011;Lewin 2012;Skowrońska-Ochmann et al 2012;Spyra & Krodkiewska 2013).…”

Impact of secondary salinisation on the structure and diversity of oligochaete communities

“…The oligochaete fauna in the presented research were characterised by a similar species diversity as that in other anthropogenic habitats such as dam reservoirs, drainage ditches, navigable canals, sand-pit, clay-pit, or subsidence ponds (e.g., Celik, 2002;Dumnicka and Krodkiewska, 2003;Heatherly et al, 2005;Krodkiewska, 2006;Dumnicka, 2007;Krodkiewska, 2010;Krodkiewska and Królczyk, 2011;Krodkiewska et al, 2016). Nevertheless, in the studied water bodies, taxa richness was significantly lower than that in natural aquatic habitats and naturally saline environments.…”

Assessing the ecological regime and spatial spillover effects of a reclaimed mining subsided lake: A case study of the Pan'an Lake wetland in Xuzhou

“…As local groundwater levels are relatively shallow, the subsidence area can flood easily, forming a large waterlogged area. As the subsided area expands due to coal mining, the permanent ponding area may become a pond or even a lake and namely a coal mining subsidence lake, which may form a wetland ecosystem over the long term [8]. As the balance of the water system is compromised, the water body may be polluted by mine water, leaching water from waste heaps, etc., destroying the landscape and reducing land productivity.…”
