Biota and Environment of Natural Areas
For the fi rst time, the spider fauna of the Salair National Park and adjacent territories is studied in detail and its zoogeographical characteristics are given. The surveys were carried out in the Togul and Chumysh cluster areas and adjacent territories in 2020–2022. An annotated list has been compiled, including 118 species from 17 families and 77 genera. Twenty seven species of spiders were recorded in the Altai Territory for the fi rst time. The genus Enoplognatha Pavesi, 1880 is new to the region. The family Linyphiidae is the most diverse. At the generic level, small- sized wolf spiders of the genus Pardosa C. L. Koch, 1847 and large orb-web spiders of the genus Araneus Clerck, 1757 are represented by the highest number of species (6 and 5, respectively). The analysis of longitudinal components of the ranges of the collected species showed a signifi cant predominance (more than 70%) of widespread, trans- Palaearctic and trans- Holarctic elements. Twenty percent of species are common to the fauna of Europe and Siberia. The predicted spider species diversity of this region is 300–350 species.
