The impact of abandoned kaolin quarries on macromycetes (Fungi: Basidiomycota, Ascomycota), carabid beetle (Coleoptera: Carabidae), and spider (Araneae) assemblages
“…Fungi have high plasticity and adaptability [75,76], and most of the fungi we observed belonged to Ascomycota (phylum), Basidiomycota (phylum), and Mortierellomycota (phylum). This was consistent with the results of many species composition analyses of fungi in mining areas, and the soil in the mining area provides an important shelter and nutrient supply for fungi [22,[77][78][79][80]. Fungi play particularly important roles in mineral dissolution, metal and anion cycling, and the formation of free-living and symbiotic forms of minerals [81], which means that fungi can also restore the ecology of mine wastelands [82].…”

“…These factors directly affect the ecological balance of the soil and the metabolism and activity of microbes and plants. Current studies have only focused on the biodiversity of microorganisms in soil from abandoned mining areas [21][22][23][24][25]. However, there is a lack of studies on the biodiversity of microorganisms in rhizosphere soil in mining areas.…”
Mining activities in the kaolin mining area have led to the disruption of the ecological health of the mining area and nearby soils, but the effects on the fungal communities in the rhizosphere soils of the plants are not clear. Three common plants (Conyza bonariensis, Artemisia annua, and Dodonaea viscosa) in kaolin mining areas were selected and analyzed their rhizosphere soil fungal communities using ITS sequencing. The alpha diversity indices (Chao1, Shannon, Simpson, observed-species, pielou-e) of the fungal communities decreased to different extents in different plants compared to the non-kauri mining area. The β-diversity (PCoA, NMDS) analysis showed that the rhizosphere soil fungal communities of the three plants in the kaolin mine area were significantly differentiated from those of the control plants grown in the non-kaolin mine area, and the extent of this differentiation varied among the plants. The analysis of fungal community composition showed that the dominant fungi in the rhizosphere fungi of C. bonariensis and A. annua changed, with an increase in the proportion of Mycosphaerella (genus) by about 20% in C. bonariensis and A. annua. An increase in the proportion of Didymella (genus) by 40% in D. viscosa was observed. At the same time, three plant rhizosphere soils were affected by kaolin mining activities with the appearance of new fungal genera Ochrocladosporium and Plenodomus. Predictive functional potential analysis of the samples revealed that a significant decrease in the potential of functions such as biosynthesis and glycolysis occurred in the rhizosphere fungal communities of kaolin-mined plants compared to non-kaolin-mined areas. The results show that heavy metals and plant species are the key factors influencing these changes, which suggests that selecting plants that can bring more abundant fungi can adapt to heavy metal contamination to restore soil ecology in the kaolin mining area.

“…The carabids and spiders were sampled using pitfall traps consisting of plastic cups (upper diameter 9 cm, depth 15 cm) filled to two‐thirds by 8% acetic acid. At each site, two such traps were placed 3 m apart (Walter et al 2023). We controlled the pitfall traps nine times, from April 29 to October 24, 2023.…”

“…Contrary to many of the earlier studies in quarry environments, which often targeted nutrient‐rich mineral conditions within biotically rich areas (Hendrychová & Bogusch 2016; Baranová et al 2021), kaolin is an extremely nutrient‐poor substrate, and the region targeted is notable for its rather simplified landscape structure and low species richness, that is, poor regional species pool (Beneš et al 2002; Zahradnický et al 2004). Still, we previously showed that even sites affected by kaolin extraction may represent regionally important replacements for grasslands or wetlands (Walter et al 2023).…”
Quarrying has a crucial impact on the environment, but it could enhance species diversity. Mining sites represent important refuges for countless species disappearing from homogenous landscapes. Our study focused on assemblages of heterotrophic communities such as moths (Lepidoptera), carabid beetles (Coleoptera: Carabidae), spiders (Araneae), and macromycetes (fungi: Basidiomycota, Ascomycota) in an active part of kaolin quarries and their immediate surroundings in the Pilsen region, Czech Republic. We compared differences between mined and unmined sites, sites with spontaneous succession and sites with replanted pine trees. In total, we recorded 178 moth, 63 spider, 27 carabid beetle, and 81 macromycetes species, including 21 Red‐listed species. The moths, carabid beetles, and macromycetes tended to inhabit unmined sites; on the contrary, open habitat spiders preferred open sites with replanted pine trees. Based on the life history traits analyses, moth species feeding on forbs and grasses prevail at the active part of kaolin quarries, where higher plant diversity was detected. Large body carabid beetles such as Carabus spp. favored unmined sites, as well as macromycetes with long‐lived fruit bodies. Open habitat and xerophilous spiders inhabited the replanted sites by pine trees where the sparse vegetation was obvious. Our results indicated that groups with radically different life histories such as moths, carabids, and macromycetes may react to mining remarkably similarly, although spiders, despite sharing predatory habits with the majority of carabids, reacted differently.
