“…Elevation was found to impact plant diversity in previous studies [29,49,50], mainly because of the correlation with climatic factors [29,50]. Increased precipitation along the elevation gradient in the Carpathians [27,51] is associated with increased site productivity [10], which in turn has been shown to increase plant diversity [28]. Additionally, higher topographic variability with increasing elevation across our study area results in greater habitat diversity [26] and thus may allow plants to find suitable habitats within small distances, therefore potentially leading to higher species richness.. On the other hand, our results also show that the effect of elevation on plant species richness was partially negative and mediated by reduced biomass of earthworms as a result of increased soil acidification with elevation (Fig.…”

24Grassland biodiversity is among the most vulnerable to land use. How to best manage 25 semi-natural grasslands for maintaining biodiversity is still unclear in many cases because 26 processes may depend on environmental conditions and indirect effects are rarely considered. 27 Here we evaluate the relative importance of direct and indirect effects of grazing intensity on 28 plant communities along an elevational gradient on a large topographic scale in the Eastern 29 Carpathians in Ukraine. We sampled 31 semi-natural grasslands exposed to cattle grazing in 30 two years. Within each grassland site we measured plant community properties such as the 31 number of species, functional groups, and the proportion of undesirable weeds. In addition, 32 we recorded cattle density (as proxy for grazing intensity), soil properties (bare soil exposure, 33 soil organic carbon, and soil pH) and densities of soil decomposers (earthworms and soil 34 microorganisms). We used structural equation modelling to explore direct and indirect effects 35 of grazing intensity on plant communities along the elevation gradient. We found that cattle 36 density decreased plant species and functional diversity but increased the proportion of 37 undesirable weeds. Some of these effects were directly linked to grazing intensity (i.e., 38 species richness), while others (i.e., functional diversity and proportion of undesirable weeds) 39 were mediated via bare soil exposure. Although grazing intensity decreased with elevation, 40 the effects of grazing on the plant community did not change along the elevation gradient. 41Generally, elevation had a strong positive direct effect on plant species richness as well as a 42 negative indirect effect, mediated via altered soil acidity and decreased decomposer density. 43 Our results indicate that plant diversity and composition are controlled by the complex 44 interplay among grazing intensity and changing environmental conditions along elevation. 45Furthermore, we found lower soil pH, organic carbon and decomposer density with elevation, 46 indicating that the effects of grazing on soil and related ecosystem functions and services in 47 semi-natural grasslands may be more pronounced with elevation. This demonstrates that we 3 48 need to account for environmental gradients when attempting to generalize effects of land-use 49 intensity on biodiversity. 50 51 53 4 55 Introduction 56 Grasslands cover more than 40% of the global terrestrial area [1] and are among the 57 most species-rich habitats in Europe [2]. As a result of their high biodiversity, grasslands 58 provide crucial ecosystem functions and services beyond that of livestock forage production 59 [3-7]. However, grassland biodiversity compared to the diversity in other ecosystem types is 60 among the most vulnerable to human impact, particularly to land-use change [8]. Of 61 extraordinary importance for biodiversity are semi-natural grasslands [2,6,7], which are 62 remnants of habitats created by tree cutting, haymaking, or low-intens...

“…In this paper, eleven circulation types were used, among which eight are advection types, two are non-advection types, and one is used in cases of unclassified situation or baric col ( Table 2). The Niedźwiedź classification was applied to analyze the impact of air circulation on different atmospheric phenomenon occurrences, for example fog (Łupikasza & Niedźwiedź 2016), precipitation (Twardosz 1999(Twardosz , 2007Kholiavchuk & Cebulska 2019) and secular changes in bioclimatic conditions (Błażejczyk et al 2003).…”

In mountain areas, air circulation plays a major role in the forming of the climate. This paper examines how it influences thermal stress in the northern Carpathians. The Niedźwiedź’s classification of air circulation was applied. Thermal stress was assessed by Universal Thermal Climate Index (UTCI). Daily meteorological and circulation data for the period 1986–2015 were used for 20 stations in Poland, Slovakia and Ukraine. Air circulation was found to have a significant impact on thermal stress. The highest UTCI values are observed at Ca+Ka (centre of the high and anticyclonic wedge or ridge of high pressure) and the lowest values at N+NE and W+NW circulation; at the Southward stations, UTCI is higher than in the Northward ones; thermoneutral days are more frequent on the southward than on the northward slopes; during N+NE, E+SE and W+NW circulation and for heat stress days, the greatest thermal privilege of the southward slopes is observed at E+SE, S+SW, Ca+Ka and Cc+Bc (centre of low and through of low pressure) types of circulation.

“…They affect all meteorological variables (Trepińska, 2002;Migała, 2005;Niedźwiedź, 2012;Cheval et al, 2014;Spinoni et al, 2014;Rubel et al, 2017;Błażejczyk, 2019). Due to their elevation above sea level, mountains are a source of several modifications of various meteorological elements such as: air temperature (Baranowski, 2003b;Żmudzka, 2009, 2011Dąbrowska & Guzik, 2015), precipitation (Sindosi et al, 2015;Kholiavchuk & Cebulska, 2019), cloud cover, solar radiation and insolation (Baranowski, 2003a;Matzarakis & Katsoulis, 2006;Żmudzka & Kulesza, 2019), wind speed and direction (Baranowski, 1999;Błażejczyk, 2019) and atmospheric phenomena (Niedźwiedź, 2003(Niedźwiedź, , 2006Błażejczyk, 2019). Important factors that also affect the mountainous climate are geographical position and orientation of mountain ridges while they influence all meteorological elements, mostly solar radiation, air temperature and precipitation (Hess, 1965;Smith, 2015;Błażejczyk & Skrynyk, 2019).…”

Thermal stress in selected mountain system in Central and Eastern Europe – initial research based on UTCI characteristics

Mountain areas create specific features of local climates (by modification of air circulation, insolation, air temperature, precipitation, wind regime) and greatly affect ambient weather conditions which influence different kinds of human (climbing, skiing, walking, etc.). However, till now only few studies of human bioclimate in individual mountain ridges in Europe were done. The aim of the present study is to assess thermal stress features represented by Universal Thermal Climate Index (UTCI) in nine mountain systems in Central and Eastern Europe. 37 meteorological stations located at altitudes of 237-3580 m above sea level were considered. The data represent midday observational term and cover the period 2000-2017. Mean, highest and lowest annual thermal stress values and annual frequency of cold and heat stress days are analysed The conducted studies have demonstrated that in the examined mountain systems thermal stress conditions are dependent (though to a various extent) mostly on altitude (UTCI values and heat stress days decrease and number of cold stress days rise significantly due to increase of altitude). However, impacts of latitude and longitude is well seen only in altitude belt of 300-1000 m a.s.l.
