Biotopical distribution and seasonal activity of model species of the family Gnaphosidae (Araneae) in Zemen gorge (SW Bulgaria)
A faunistic study was carried out for three years in Zemen gorge (1984-1986). With the help of Barber-traps 675 gnaphosid spiders were caught in 4 localities, each with 2 habitats, meadow and forest. 23 species were found in total and their biotopical distribution was recorded. The investigated habitats are faunistically similar, mainly in qualitative respect. In addition data about the phenology of the most frequent species are presented. The males are most abundant in spring and summer and disappear in VIII, the females are most numerous after VII and can be found till the end of IX, whereas the juveniles can be found till the end of X. The species abundance reaches its peak in V-VI.
