Colonization of reclaimed post-mining habitats by Myriapoda (Diplopoda, Chilopoda) in southwestern Siberia, Russia

Post-mining landscapes undergo profound ecological transformations, yet the recovery of soil fauna remains poorly understood. This study examines the colonization patterns of myriapods (Diplopoda and Chilopoda) on reclaimed coal mining dumps in southwestern Siberia (Kemerovo Oblast, Russia) across different successional stages. From 2014 to 2017, we sampled two coal mining sites, comparing dumps of varying recovery ages with undisturbed control habitats. Results reveal stark contrasts between the two myriapod groups: Diplopoda exhibited low abundance and species richness, colonizing only at later successional stages, influenced by soil pH, organic carbon, and vegetation cover. In contrast, Chilopoda rapidly colonized young dumps, with pioneer species like Lamyctes africanus dominating early successional stages. Statistical modeling identified soil moisture (HTC), nitrogen content, and pH as key drivers of myriapod distribution. These findings highlight the slow recovery of millipede communities compared to centipedes, which act as early colonizers shaping trophic networks. The study underscores the need for targeted reclamation strategies that enhance soil conditions and vegetation to facilitate soil fauna restoration. Understanding these successional dynamics can improve biodiversity recovery in post-mining ecosystems.
