Abstract

We applied dendrochronological methods for dating landslide activity in the study area (3.75 km2), on the slopes of Sucha Mountain (1040 m a.s.l.), in the Beskid Żywiecki Mountains, in the Western Carpathians. 46 sampling sites were distributed throughout the study area. At each site we sampled 1-3 coniferous trees: Norway spruces (Picea abies Karst.) and/or silver firs (Abies alba Mill.). From each tree 2 cores were sampled: one from the upslope and the other from the downslope side of the stem. Based on tree-ring widths measured for opposite sides of stems we have calculated eccentricity index values and dated past landslide events. Mean frequency of landslides was obtained for each sampling site. Finally, the data was interpolated into a map of landslide activity. Inverse Distance Weighting (IDW) interpolation has been applied. For most of the study area we found medium (19 sites) and low (23 sites) levels of landslide activity. The highest level of activity was recorded for the largest landslide slope and for the one small landslide. The study conducted on Sucha Mountain has shown that dendrochronology can be an effective method for analysing landslide activity and may be useful in further studies, including those for landslide hazard and risk assessments.

Abstract

The authors evaluate the impact of different types of forestry management, and other anthropic disturbances, on harvestmen (Opiliones) communities in sub-mountain beech stands in the Western Carpathians. Harvestmen were studied in three main localities, consisting of nine partial plots (Žiar nad Hronom - (1) control closed canopy stand; Jalná - (2) control stand, (3) thinning stand, (4) 11-year old forest clearing, and (5) 2-year old forest clearing; Kováčová - (6) control stand, (7) coppice, (8) 10-year old forest clearing, and (9) 3-year old forest clearing). In total, 16 harvestmen species were found, representing 45.7 % of the 35 harvestmen species range known in Slovakia to date. Th e most abundant species, i. e., those with the highest dominance values (D), were Lophopilio palpinalis (D = 22.8%), Trogulus nepaeformis (D = 17.9%), Lacinius ephippiatus (D = 12.2%), Trogulus tricarinatus (D = 11.3%), Oligolophus tridens (D = 10.5%), and Nemastoma lugubre (D = 6.7%). At the partial plot of the 3-year old forest clearing, we found eight harvestmen species and noticed a high number of specimens (5.49) caught in one individual trap, and this was also the highest number among all the nine sites.

Recent findings of mosses from Orthotrichaceae family (Bryophyta) in the Czech part of the Western Carpathians. Part 1. The Moravskoslezské Beskydy Mts and its foothills

Recent distribution of mosses within Orthotrichaceae family in Moravskoslezské Beskydy Mts and its foothill is done. Particularly interesting findings are briefly commented. Among others, findings of the threatened species, e.g. Orthotrichum patens, Zygodon rupestris, are presented.

Abstract

Snowbed vegetation is one of the most sensitive alpine vegetation type to the climate change, because shortened period of snow cover has essential impact on the snowbed environment. We focus on its changes in the Western Tatras, which is a part of the Western Carpathians (Slovakia). The assessment of changes in snowbed vegetation is based on the method of pair comparison. In 2016–2018, we resampled 21 historical phytocoenological relevés of Festucion picturatae and Salicion herbaceae alliances from 1974 and 1976. Historical data include 45 species, while recent data include 50 species. We observed a decrease in the frequency of species characteristic for snowbeds and, on the other hand, an increase in that for strong competitors, especially grasses and small shrubs from adjacent habitats. According to Ellenberg’s ecological indices, there is some increase in temperature and decrease in light ecological factors in snowbed habitats. In S. herbaceae data, a statistically significant increase in the average species number was observed with new species that penetrated from the adjacent habitats. Changes in species composition between historical and recent data are confirmed by Non-metric multidimensional scaling (nMDS) ordination diagram. Linear mixed-effect models showed big variability in factors that have impact on phytodiversity; nevertheless, temperature is the most significant factor.

hazard map on larger areas where there are both landslides with typical relief and areas without landslide relief. There are no examples of landslide hazard maps created on the basis of dendrochronological results for the entire mountain ridges or massifs. Therefore, the aim of the study was to develop a landslide hazard map for the massif of Sucha Mt (Beskid Żywiecki Mts, Western Carpathians, southern Poland), and also to propose a method which combines dendrochronological and geoinformatic tools to assess the spatial variability of landslide hazards over larger areas
