First Data On Spider Communities (araneae) Of Recultivated Ash Dumps. A Case Study Of Luhansk Thermal Power Station, Ukraine
N. Yu. Polchaninova, P. V. Foroshchuk
A total of 36 spider species from 8 families was registered on a recultivated ash dump of the Luhansk thermal power station. The families Lycosidae (13 species) ? Gnaphosidae (8 species) had the highest diversity. Three families dominated in individual numbers: Lycosidae (59.3 %), Philodromidae (17.2 %), and Gnaphosidae (13.8 %). The species diversity of spider community in biotopes near the station was lower (18 species) than in biotopes at a distance of 500 m (20 species) and 1000 m (22 species). The highest number of spiders was at a distance of 500 m and the lowest was registered near the station. An increase of species diversity of spider communities with the distance from the station was not registered. The spider communities of ash dump were closer to natural steppe communities than to spider communities of technogenic areas by species richness and hierarchical structure.
