It is clear that many species have similar habitats, as defined by majority preference, e.g., both Halorates thulensis and Diplocephalus barbiger prefer gravel and heath, Hybauchenidium aquilonare and Hilaira vexatrix prefer heath, and Hilaira proletaria and Halorates holmgrenii prefer sedge.
Preferences of other species seem to differ: Alopecosa hirtipes, Agyneta maritima, Erigone arctica, Hilaira vexatrix, and Silometopoides pampia prefer mixed areas on Southampton Island but either moist or dry areas elsewhere; Diplocephalus barbiger and Halorates thulensis prefer dry areas on Southampton Island but moist areas elsewhere, and Oreoneta brunnea and Halorates holmgrenii prefer moist areas on Southampton Island but dry areas elsewhere.

Many species with a cosmopolitan range are absent from Siberia, like Ostearius melanopygius (O.P.-Cambridge 1879), Tenuiphantes tenuis (Blackwall 1852), Diplocephalus cristatus (Blackwall 1833), and two Oecobius species.
The genera with the highest number of species are: Centromerus (16 species or 7.3%), Walckenaeria (14 species or 6.4%), Tenuiphantes (11 species or 5%) and Diplocephalus (9 species or 4.1%) (Table 2).
