The Spring Aspect of the Herpetobiontic Spider Assemblages (Araneae) of Some Biocenosesforming the Row Meadow – Birch Forets Ofmordovia

Spiders and harvestmen (Arachnida: Aranei, Opiliones) of the revegetating ash dumps of a combined heat and power plant in Novosibirsk (Russia, West Siberia)

“…In open, warm sunny plots of the ash dump, with a well-developed grass layer, more diverse spider taxocens were formed, as compared to that of the birch forest. Similar results were obtained in the study of meadow fallows and birch forests of various ages in Mordovia [Agafonova et al, 2019].…”

“…Both in summer and in autumn, the dominance structure of spider taxocens between non-reclaimed and reclaimed sections, as well as those of all the plots studied, showed no significant differences. Elsewhere, there were few abundant and lots of rare and less abundant species in spider taxocens, which is quite common for Aranei [Esyunin, Shumilovskikh, 2008;Agafonova et al, 2019]. Thus, the process of populating ash dumps by spiders proceeds quite quickly, and by the 9th year of self-revegetation had resulted in the formation of spider communities typical of undisturbed landscapes.…”
