Abstract:The distribution of epiphytic bryophyte and lichen species growing on aspen in the middle boreal forests was studied in southern Karelia (Russia). These forests varied in time-since-disturbance from 80 to 450 years. (2007) were found. Relationships between epiphytic lichen and bryophyte species richness and certain environmental variables (at different trunk heights above ground and time-since-disturbance) were evaluated. Lichens and mosses on aspen trunks often occupy different ecological niches. Cover and diversity of bryophytes was high on trunk bases, while the number of lichen species and their cover were higher at a height of 1.3 m above ground level. The total number of lichen species on aspen increased on average from 40 to 60 species per ha with increasing time-since-disturbance from 100 to 450 years. A stabilization in lichen species number was observed at about 200 years since disturbance. No significant correlation was determined between bryophyte diversity on aspens and the time-since-disturbance.

Liverworts flora of the Pasvik State Nature Reserve (Pasvik Reserve) consists of 103 species, 5 subspecies and 2 varieties. We have summarized all available data on the diversity of liverworts of the Pasvik Reserve, including approximately 650 specimens collected by the authors. Calycularia laxa and Oleolophozia perssonii are reported for the second time from Murmansk Region. The territory is quite representative for protection and sustainable development of rare liverworts species – we found new localities for four red-listed European species (Barbilophozia rubescens, Haplomitrium hookeri, Lophozia ascendens and Nardia japonica), three liverworts included in the Red Data Book of the Russian Federation (Haplomitrium hookeri, Nardia breidleri and Oleolophozia perssonii) and 12 red-listed in the Murmansk Region.
