“…This result is in accordance with previous research (Mežaka & Znotiņa, 2006;Mežaka et al, 2012;Putna & Mežaka, 2014). This might arise, however, by the low number of mosses and liverworts in sample plots characterized by relatively short time after disturbance (80-100 years).…”

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.

“…For example, stand-level patterns in epiphytic bryophyte community composition and diversity depend strongly on the structures and topographic characteristics of the edge habitat (Murcia, 1995;Didham & Lawton, 1999;Leung & Marion, 2000;Kiraly et al, 2013), while at the tree level, host traits such as the orientation of facing edges (Kivistö & Kuusinen, 2000), the diameter at breast height (DBH), and the height of the sampled quadrat (Belinchó n et al, 2007;Oliveira et al, 2011) are important. Mežaka et al (2012) found that the variables at tree level were more important than those at stand level in explaining the composition and richness of epiphytic bryophytes on trunks. Thus, in the present study, we focused on the tree-scale level to evaluate the effects on epiphytic bryophyte community and biodiversity resulting from trail construction and visitor activities.…”

Forest hiking trails may influence local microclimate and biodiversity, but the effects on community structure and diversity of epiphytic bryophytes on trees are currently unknown. Epiphytic bryophytes on 82 Abies faxoniana Rehder & Wilson tree trunks (41 along the hiking trail edge and 41 controls in the forest interior) were investigated at four heights from the ground (10, 50, 120, and 180 cm). At each site, air temperature and humidity were monitored for 1 year. The light radiation levels and air temperature were higher, and the canopy leaf area index and air humidity lower at the trail edge, indicating deterioration in microclimate, resulting from the trail establishment. The epiphytic bryophyte species richness, community cover, and mean cover of dendroid and pendent growth forms on trunks were significantly lower at the trail edge than the control site, suggesting that trail construction caused these reductions. One marked effect of the presence of the trail was the increase in some sun-loving species and decrease in shade-tolerant species. Moreover, the trail also slightly influenced species richness and epiphytic bryophyte cover at both community and species population levels along the height gradient. Comprehensive analyses showed that microclimate deterioration was mainly driven by the trail establishment, and that the change in microclimate along the trail, rather than any host traits, played an important role in the declining epiphytic bryophyte community structure and diversity at the trail edge, confirming the initial hypothesis that the presence of a raised boardwalk (hiking trail) indirectly influences epiphytic bryophyte community and diversity by altering the microclimate.Keywords: Biological conservation, Epiphytic bryophytes, Habitat edge, Old-growth forest, Raised boardwalk IntroductionHiking trails are one of the key infrastructure elements in protected areas including forest parks, and are often established with the intention of reducing direct visitor disturbance to the ground vegetation, forest, and environment, especially trampling damage and impaired regeneration (Cole, 1978;Boucher et al., 1991;Li et al., 2005). In establishing hiking trails, long narrow openings are created through the forest. However, it is believed that the trail construction and consequent influx of large numbers of visitors can have negative effects on the surrounding habitats and vegetation (Hall & Kuss, 1989;Li et al., 2005;Maciel et al., 2011). Hiking trails through forests are becoming an important element of the infrastructure management of forests because of the increasing development of forest tourism worldwide. However, the biological effects of such trails have been insufficiently investigated and thus, are still largely unknown. An understanding of the effects of trail formation and visitor activities on biodiversity is essential for conservation managers seeking to minimize human influence on such sites, where large numbers of visitors can negatively affect the biodiversity conservation of forests (Bo...

“…White elm has been shown to be important for the conservation of epiphytic bryophyte and lichen communities in Latvia (Mežaka et al 2012), as well as for millipede (Diplopoda) communities in Slovakia (Stašiov et al 2012). Moreover, extracts from U. laevis may also be useful for developing drugs against cancer (Paschke et al 2009, Hartmann et al 2011.…”
