Assembly of heterotrophic communities during spontaneous succession in quarries: invertebrates model groups and macromycetes

Abstract

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.
