Abstract The flysch areas belong to the territories with highest occurrence of landslides in Slovakia. Almost 67% of all landslides in Slovakia take place within the Carpathian flysch. It is a type of slope deformation that responds sensitively to the quality of individual factors that form the landscape and to the change in natural conditions. The occurrence of various geodynamic phenomena can be understood as a geological barrier that reduces or inhibits the use of natural environment and negatively affects the life of society and territorial development. In this paper, we evaluate the statistical significance of selected natural factors of the landscape in relation to the occurrence of unstable slopes in the Kysuce region. In addition, we also evaluated the expansion of unstable slopes in individual landscape factors. Significant linkages between the variables’ hydrogeological base_sandstones with thin clay layers (HB_s) and geological-substrate complex_loamy wastes to loamy-stony debris on sandy conglomerates (GSC_sc) (R = 0.95, p = 0.002) and secondary significant linkages between the variables soil type: Dystric Cambisols (S_CMd) and HB_s (R = 0.40, p = 0.002) (Klokočov and Zákopčie cadastres) were observed. Significant correlation of variables within the areas with unstable slopes was also observed between hydrogeological base_sandy flysch (HB_sf) and geological-substrate complex_loamy wastes on flysch stones (GSC_fs) (R = 0.81, p = 0.002) (Nová Bystrica and Kysucké Nové Mesto cadastres). The most unstable slopes occur in Nová Bystrica cadastre (34.62% of the area) and in the Klokočov cadastre (28.25% of the area). The inclination of slopes (especially slopes above 12°) plays an important role within the unstable slopes. Slopes with steep inclination cover up to 81.45% of the cadastral area of Nová Bystrica, of which almost 1/3 are unstable slopes.

Purpose of the noise barriers is to create an acoustically sufficient impermeable obstacle located on the sound wave propagation path, thereby creating a shadow of the sound pressure level behind the barrier. The paper is focused on the analysis of measured noise values at specific selected points of the railway track in the region of Kysuce without noise barrier and on the determination of noise barrier efficiency. The observed values are compared with the permissible noise values specified by the Slovak legislation

AbstractTourism is an industry with a strong long-term potential of becoming one of the key industries in securing the country’s economic growth. Tourists are nowadays interested in not only getting to know the cultural-historical peculiarities, but also the way of life and cultural traditions of the inhabitants of the individual regions. Kysuce region is characterised by scattered settlement, which used to be a significant type of settlement in remote and inaccessible parts of the area in the past. Nowadays, however, the majority of the objects of the scattered settlement either serve as holiday chalets or are uninhabited.The aim of this paper is to evaluate the recreational potential of tourism in Kysuce region. Based on the established methodology, the individual villages were divided into five categories: areas with less suitable potential of tourism development (PTD), areas with suitable PTD, areas with quality PTD, areas with PTD of high quality and areas with the most significant PTD. These categories have been established based on the point evaluation of the potential of input indicators – natural potential, cultural-historical potential, recreational infrastructure and environmental infrastructure. The most significant PTD in the monitored area is the village of Oščadnica (279 points), and the villages of Horný Vadičov (231 points), Raková (224 points) and Nová Bystrica (219.5 points) were evaluated as the areas with PTD of high quality. Agro-tourism in this region is, however, the least developed, despite the location of the region being very favourable for such an activity. Its development could lower unemployment and offer a source of income of the inhabitants, or reduce movement of the inhabitants into other regions of Slovakia. Subsequently, the character of the landscape with all its key functions for sustaining the quality of the environment could be preserved.

Full textAbstract:
An analysis of the status of spruce stands in the Kysuce and Orava region was performed and their health condition was compared to the spruce forest constitution in the rest of Slovakia. For this purpose, the inventory plots established within the first circle of National Forest Inventory (NFI) in 2005 and 2006 were used. The Kysuce and Orava regions significantly differ from the rest of Slovak forests by its high proportion of spruce. The health status of the spruce stands in these regions, according to the salvage felling as a result of the damage caused prevailingly by stem rotting and bark beetles appears worse than in the rest of Slovakia. The analysis showed that not only the acute damage of spruce stands (insects) but also the chronic damage of trees (rotting, mechanical damage during logging) is more serious in these regions than in the rest of Slovakia. The browsing caused by deer game (data does not include young stands) in both regions as well as in the rest of Slovakia seems to be low and not so serious compared to the previously mentioned types of damage. Other sorts of damage (stem breakage, standing dead trees, or damage by insect) have also small proportion. More detailed analyses of NFI data with acceptable precision were possible only for most frequent kinds of damages such as stem rotting and damage by logging. The results showed the frequency of rotting tended to be higher with increasing stand age. Influence of altitude on the frequency of the damage was not evident. Since variability of selected types of damage on spruce forest in the target regions was high, all results are presented with the precision at 68 % confidence interval.

Full textAbstract:
Biotic agents driven spruce decline has been observed over several regions in Europe. We studied the spatial pattern of spruce stands mortality due to biotic agents in three spruce dominated regions in Slovakia – the Kysuce, Orava and Low Tatras regions. Regularly reported data on sanitary felling were used for the analysis. Geostatistical techniques and other spatial modelling tools were used to design the zones of biotic hazard for each region. Zone A stands for the totally disintegrated stands with extremely elevated activity of biotic agents. Zone B represents the buffer zone around the zone A. Its width depends on the spreading potential of biotic agents and related stand mortality observed during the last years. Zone C stands for the background areas, with more or less healthy stands. Zone-specific forest protection measures are proposed. Such a system allows for the priority rating of unnatural spruce stand conversion and optimal allocation of forest protection measures.

AbstractThe growing development of settlements in mountainous areas and their sustainable development constantly requires new approaches to assess the land in terms of occurrence of landslides. The flysch zone, where the monitored area is located, is one of the most landslide prone areas in Slovakia. Landslides respond sensitively to the quality of the individual factors that form the landscape and to the change of natural conditions. Their occurrence is a geo-barrier that reduces or totally prevents the use of natural environment and negatively affects the life of population and territorial development. The reason for the increased hazard of landslides is not only demographic pressure on territories, but also its poor management. Consistent spatial planning addresses not only the spatial layout but also the functional use of the territory. Landslides represent one of the limits of land use. This study is based on the assessment of landsliding as a limit to possible territorial development. The input parameters for the assessment were elements of the current landscape structure (built up structure, forest stands, transitional woodland-shrubs, traditional agricultural land, permanent grasslands and arable land) and occurring landslides (active, potential and stabilized). On most of the determined elements of the landscape, landslides occur on about a quarter of their area. They have a smaller share only in areas of mixed forests, built up areas and have the smallest share on arable land. Potential landslides have the largest proportion on all landscape elements. They occupy the largest areas on coniferous forests (1578.93 ha) and on permanent grasslands (741.33 ha). By evaluating the overall endangerment of the area by landslides according to the degree of threat, we found that the greatest threat of landslides is in the Skalité and Svrčinovec cadastral areas, the smallest threat is in the Čadca cadastral area. In addition to the danger of landsliding in the individual elements of the landscape, we have also set limits for its development. Spatial planning limits have been divided into two categories according to the sectors they affect the most: limiting the development of an area assigned for residential building, or restricting the development of an area designed for agricultural and forestry purposes.

Border studies (currently also cross-border cooperation issues) is an interdisciplinary research specialization. The aim of the article is to present the spatial proximity influence of the state border on the everyday life reality of inhabitants of the Kysuce region in the 20th Century (overlapping with the present day) in both the local and supra-local context. With reference to the theory of the Irish sociologist Liam O'Dowd, it focuses on the Slovak state borders with Poland and the Czech Republic as a possible barrier, but also a bridge, a source of opportunities and a symbol of identity. It points out that in the villages bordering the Polish and Czech territories there has always been a relatively intensive mutual cultural transfer and contact of populations and therefore the borders cannot be perceived as an exclusively geopolitical phenomenon; their social and cultural dimension must be taken into account.

Abstract The North Atlantic Oscillation (NAO) is the most important circulation phenomenon in the Northern Atlantic which impacts climate in Europe in various ways. Precipitation is a basic climatic element which affects the landscape significantly. Therefore in this paper, the relationship between the NAO and winter precipitation in Slovakia is analysed. A Spearman’s correlation analysis was used, which detected the impacts of NAO on the above-mentioned seasonal precipitation in different regions of Slovakia. The correlation coefficients obtained positive values in the region of Orava and Kysuce and changed to negative ones in a southward direction. The detected zonal configuration can be explained by the topographic barrier effect of the Carpathians

The study concerns a monitoring survey of Cordulegaster bidentata Selys, 1843 (Odonata, Cordulegastridae), which is considered near threatened in the European Red List of Dragonflies, in order to show its habitat preferences and clarify the influence of slope and orientation of slopes on the occurrence of the species. Investigations of water habitats were carried out during the period from 2019 to 2020 in the Kysuce Region in northwest Slovakia. The protocol consists of looking for larvae and characterizing larval micro-habitat of C. bidentata so as to show their habitat preferences and clarify the influence of slope and orientation of slopes on the occurrence of the species. We sampled 32 watercourses (epicrenal, hypocrenal, rheocren, heleocren, epirhithral, metarhithral) at altitudes 420–950 m above sea level. A total of 79 larvae and 10 imagines (7♂ 3♀) of C. bidentata were found at 12 streams. In the present study, C. bidentata clearly preferred first-order stream sections, the slopes were steep and the proportion of small sediment grain sizes was high. The results show that the number of C. bidentata larvae grew with the increasing percentage of forests around streams. We also confirmed the trend for the number of C. bidentata larvae to increase with increasing values of slope and altitude of watercourses. Most of the individuals were recorded at the south and southwest oriented streams; we did not record larvae on the north and northwest oriented slopes. We assume that more suitable conditions for development of population exist in the streams on the south and southwest oriented slopes. The preference for watercourses oriented south and southwest ensures optimal conditions for the development of the population of this dragonfly species. The finding of larvae at the stages of instars shows the permanent occurrence of the species in the Kysuce Region.

Abstract Traditional agricultural landscapes (TAL) are landscapes in which primarily traditional sustainable agricultural practices are currently carried out and where biological diversity is conserved thereby. The objective of this paper is to evaluate the extension of traditional landscape structures and their relationship to geological substrate and slope processes (landslides). The evaluation was concentrated on two types of TAL (extended to Kysuce region): TAL with dispersed settlements (subtype 1a and b) and TAL of arable-land, grasslands and pastures (subtype 4a and b). Localities with typical dispersed settlements of subtype 1a mostly occur on Zlin formation and cover 707.9 ha. On the deluvial formation, this type extends to 531.8 ha and on the Solaň formation, to 403.6 ha. The active landslides are mostly represented in the TAL of subtype 4a (cadastral areas of Čadca and Oščadnica villages), of subtype 4b (cadastral areas of Riečnica and Svrčinovec villages) and of subtype 1a (cadastral area of Svrčinovec village). The largest representation of potential landslides is on the subtype 4a, subtype 1a and subtype 4b.

Abstract Territory of Kysuce is characterised by a high proportion of the traditional agricultural landscape (TAL), which occupy almost 12% of the area. Two types of TAL were allocated here. The first type is represented by TAL with dispersed settlement. The second type is represented by TAL of arable land and grassland landscape. The largest representation has typical forms of anthropogenic relief (FAR). TALs represent the most diverse mosaic of man-made habitats and natural habitats too. In the past, there were the largest representations of arable land and regularly mown meadows. Currently, these areas are dominated by abandoned meadows (fallow meadows), occasionally grazed pastures and meadows. Arable land is represented only minimally. The large part of areas is overgrown by non-forest woody vegetation or passes to the forest vegetation. In this process of landscape changes, significant changes in biodiversity of the areas are realised. Successively, the species of segetal and ruderal vegetation are less represented and species of forest vegetation obtained greater representation. In the process of mapping and evaluation, FAR - shape and orientation of plots, types of balks and some of their basic characteristics - were monitored.

The paper deals with environmental risk assessment in prevailingly unnatural spruce (Picea abies [L.] Karst.) forests in three regions with different patterns of forest damage in the Slovak part of the West Carpathians. Logistic regression was used to estimate the effect of 7 site-related, 5 stand-related and 2 anthropogenic factors on the probability that critical forest damage will occur. The results show that regression models can describe cause-effect relationships in regions with different regimes of forest decline. Stand age, proportion of spruce, and distance from the focus of biotic agent activity predicted decline in two regions with generally lower elevation in northern Slovakia (Kysuce and Orava). In a mountain region (Low Tatras), the importance of factors contributing to the static stability of trees and position towards dangerous winds increased significantly. The quality of the derived models and prospects for their usefulness in risk assessment are discussed.

Abstract In the period from 1992 to 2013, more than 3.8 million m3 of spruce wood from an area of 55 thousand ha of forests in the Kysuce region (Western Carpathians) was affected by bark beetles. This region has had the highest volume of salvage fellings in Slovakia. While before 1991, bark-beetle outbreak usually occurred after snow and wind disturbances, since 1992 they have occurred in the years with extremely warm and dry growing seasons and the years following them. These years were also characterised by high volumes of wood affected by honey fungus (Armillaria spp.), which only rarely took part in the calamities before 1992. Extreme deterioration of the situation occurred after 2003. In fragmented and sparse stands, the volume of wood damaged by wind increased. Artificial origin of spruce stands, their high occurrence, high age and even-agedness are likely pre-disposing factors of spruce forest decline. Bark beetles have become the most important factor of spruce decline. The most important factors driving the bark beetle attack on forest stands in the period 1973–2013 were the amount of unprocessed wood in the previous year; the amount of wood affected by honey fungus, precipitation total, and average temperature in the current growing season. Another important factor that complicated the situation was also the inferior quality of forest management.

Traffic volume depends on several indicators. The most important are the degree of motorization, mobility, and especially the travel time and travel cost factor. The article presents an analysis of the possibility of using mobility surveys and traffic counts to achieve a balance between supply and demand. The frequency of congested traffic and over-capacity volumes are determined. By analyzing the trip information captured in the mobility surveys, we detected the strata causing the highest demand—economically active people with “job” as the purpose of their trip. The study area includes the Kysuce region and the city of Žilina in Slovakia. Three scenarios are processed in the article. Scenario 0 defines the current state, scenario 1 defines the situation with free-of-charge public transport, and scenario 2 represents a targeted modal split where saturation is not exceeded. The aim is to shift passengers to public transport and increase the share of public transport in the modal split. Scenario 2 is also presented in terms of saved emissions as an additional factor of relocating passengers from private to public transport. In terms of fare, we found a small change in the modal split with free-of-charge public transport.

Full textAbstract:
Previously, we developed a novel EGFR-targeted antibody (denoted as Pan), which has superior antitumor activity against EGFR-overexpressed tumors. However, it shows marginal effect on the growth of esophageal cancers. Therefore, the variable region of Pan was fused to a fragment of Pseudomonas exotoxin A (PE38) to create the immunotoxin, denoted as Ptoxin (PT). Results indicated that PT shows more effective antitumor activity as compared with Pan both on EGFR-overexpressed KYSE-450 and KYSE-150 esophageal cancer cells, especially on KYSE-450 cells. Moreover, treatment of PT induces regression of KYSE-450 tumor xenografts in nude mice. Furthermore, we investigated the potential mechanism involved in the enhanced antitumor effects of PT. Data showed that PT was more potent in reducing the phosphorylation of EGFR and ERK1/2. More importantly, we for the first time found that PT was more effective than Pan in inducing ROS accumulation by suppression of the Nrf2-Keap1 antioxidant pathway, and then induced apoptosis in KYSE-450 esophageal cancer cells, which may partly explain the more sensitive response of KYSE-450 to PT treatment. To conclude, our study provides a promising therapeutic approach for immunotoxin-based esophageal cancer treatment.

Il est recommande de faire une kystectomie ou une peri-kystectomie des kystes accessibles et sans danger et une kystectomie partielle pour les kystes profonds et au contact avec leselements vasculaires. Le traitement medical est peu efficace il est indique en cas de contre-indication operatoire ou en cas de localisations multiples ou si la resection est incomplete. Conclusion: Bien que rare, le diagnostic de kyste hydatique pelvien doit etre evoque devant toute malade presentant une masseabdominopelvienne. La kystectomie est le traitement de choix. Le traitement medical peut etre utilise en deuxieme intention.

Infestation density of four the most common spruce bark beetle species was estimated on 15 study sites (10 trees per site) in the Kysuce model region in 2006. Five half-metre long sections of the stem were selected and dissected at the base of the stem; midway between the base of the stem and the base of the crown; just below the base of the crown; in the middle of the crown; and in the upper part of the crown. The infestation density of bark beetles, expressed as the number of mating chambers per dm<sup>2</sup>, was determined. Ordinary kriging was then used to produce smooth maps and visualize spatial distribution of study species. Maps with isolines indicating high infestation were produced for study species (<I>I. Typographus</I> over 0.38; (<I>I. amitinu</I>s over 0.15; (<I>I. duplicatus</I> over 0.11; and <I>P. chalcographus</I> over 0.415 nuptial chambers per dm<sup>2</sup>). <I>Ips typographus</I> L. remained dominant species on majority of sites having high intensity of infestation. Lower altitudes in the south-eastern part of the region were often infested by <I>I. duplicatus</I> Sahlberg and also by <I>I. typographu</I> and <I>Pityogenes chalcographus</I> L. Higher elevations in the north-eastern part of territory in the vicinity of border with Poland were heavily infested by <I>I. amitinus</I> Eichhoff (often with <I>I. typographus). P. chalcographus</I> was abundant on majority of territory – mainly in southern half of area. However locally, it was found in extremely high abundance. The results suggest the need for control measures set up jointly against the most abundant bark beetle species in study region.

Full textAbstract:
Large wild herbivores are important and natural components of forest ecosystems, but through their browsing activities have the potential to influence the structure and composition of forest communities, thus timber production and ecosystem dynamics. To examine the effects of browsing by wild herbivores on a young post-disturbance forest in the Kysuce region of northwestern Slovakia, we established two sets of 2 m radius plots, 15 within a fenced area (5.12 ha) that excluded large wild herbivores, and 15 within an adjacent unfenced area. In each plot, we recorded the species, tree height, stem base diameter, and mutual geographic positions of trees. When we compared tree community characteristics between the unfenced and fenced plots, we found fewer and smaller broadleaved tree species, except silver birch (Betula pendula Roth.) in the unfenced plots. Although common rowan (Sorbus aucuparia L.) was the dominant species within fenced plots, where some individuals were over 6.0 m tall, this species was rare outside the fenced area and usually did not exceed 1.5 m. In contrast, Norway spruce (Picea abies Karts L.) was more abundant and taller within the unfenced area, likely released from competition by suppression of broadleaved trees by herbivores. In addition, fenced plots also showed twice the tree species richness (Shannon index) of unfenced ones. Despite changes in tree communities, total aboveground biomass stock was only slightly but significantly lower in the unfenced than the fenced plots (29.6 kg per 10 m2 vs. 33.5 kg per 10 m2). Our study suggested that browsing pressure by large wild herbivores that focused on most broadleaved trees weakened interspecies competition and allowed the expansion of Norway spruce. As a consequence, converting spruce monocultures to mixed species stands is likely unrealistic when faced with heavy browsing pressure by wild large herbivores.

Abstract Amplified ITS region products of rDNA from 25 valid species and one unidentified species from the genus Heterodera and from Meloidodera alni were digested by 26 restriction enzymes. A combination of seven enzymes clearly separated the agriculturally most important species from each other and from their sibling species. Species specific digestion profiles of ITS regions and a table with approximate sizes of digested fragments for several identification enzymes are given. Heterogeneity of ITS regions was revealed for some cyst forming nematode species. Des fragments amplifiés de la région de l’ITS du rDNA de 25 espèces valides et d’une espèce non identifiée du genre Heterodera et de Meloidodera alni ont été soumis à une digestion par 26 enzymes de restriction. La combinaison de sept enzymes a permis une séparation nette des espèces les plus importantes en agriculture, tant les unes par rapport aux autres que par rapport aux espèces jumelles. Sont donnés les profils spécifiques de digestion des régions de l’ITS et un tableau regroupant les tailles approximatives des fragments digérés pour plusieurs enzymes d’identification. L’hétérogénéité des régions de l’ITS a été révélée chez quelques espèces de nématodes à kyste.

Artikkeli käsittelee venäläisten kirjallisuuden- ja kulttuurintutkijoiden 2000-luvulla kehittämää ”pohjoisen tekstin” (Severnyj tekst) kulttuurista konseptia. Aineistona ovat artikkelikokoelmat (2014–2017), joissa erityisesti Arkangelin Pohjoisen (arktisen) federaatioyliopiston tutkijat esittelevät pohjoisen tekstin konseptia ja sen soveltamista kaunokirjallisuuteen. Artikkeli tarkastelee konseptia geopoetiikan ja geokulttuurin näkökulmista ja kysyy, mikä on kirjallisuudentutkimuksen rooli alueellisen identiteetin luomisessa ja kansakuntaa rakentavien ideologisten merkitysten synnyttämisessä. Kulttuurisemioottinen konsepti yhdistää kielen, kirjallisuuden, filosofian ja tilan tutkimuksen. Kyse on pohjoista kartoittavasta metatekstistä (sverhtekst), joka esittää pohjoisen alueen ”sakraalin maantieteen” mytopoeettisena tilana ja jonka retoriikka luodessaan kansallista ja etnistä yhtenäisyyttä sulauttaa toisiinsa alueellisia ja valtion rajoja.
The “Northern Text” – literary studies creating a national ethos?
Regional narratives are actively examined in area studies and Slavic studies, but it is less-known how artistic renderings of spatial belonging and regional identity become included in current state ideologies. Drawing on cultural semiotics, geopoetics and geoculture, we highlight how the concept of the Northern text is applied to the text corpus of Russian literature on the North. Having examined the collections of articles published by Russian scholars based in Arkhangelsk in Northwest Russia in 2014–2017, we show, first, that the concept of the Northern Text combines language, literature, philosophy and space-oriented research in cultural semiotics; second, that the image of the northern region has been read through “sacred geography”; and third, that the rhetoric of the concept creates national and ethnic unity in the nation by merging the borders of the region and the state.

Notes on the reproduction, breeding biology and ethology of the Eurasian pygmy owl (Glaucidium passerinum) in Slovakia Accessible data on 78 breeding occurrences of the Eurasian pygmy owl (Glaucidium passerinum) in Slovakia are evaluated. Data from the oldest known breeding in 1846 up to 2010 were used. The breeding of this species has been proved in 24 orographic units, at altitudes from 450 (400) to 1450 m. Distribution of the species in Slovakia closely follows the distribution of fir (Abies alba) and spruce (Picea abies) and breeding has also been recorded in forest habitats with an abundance of scots pine (Pinus silvestris) and black pine (Pinus nigra). From the point of view of natural and secondary origin of these forest habitats, the species breeds in both ‘natural’ habitats such as montane spruce forests and Euro-Siberian coniferous forests, forests with beech and fir, oak-hornbeam forests with lime and fir, as well as in secondary forest spruce plantations. From 22 evaluated Slovakian nests as many as 17 (70.8%) were situated no farther than 200 m from water. A high number of nests (72.5%) were situated at altitudes between 600-1100 m, with 13% above this range and 14.5% below. As many as 25 nest holes were located in spruce, both living and dead, and in snags, ten in fir (with a significant number of dead stumps), six in beech, four in oak and four in aspen. Nests were also found on one occasion each in larch, maple and black pine. On one occasion breeding took place in a nest-box. On several occasions the same nest hole was used repeatedly, with the highest number of such occasions being four times in the same tree in an eight year period. On three occasions a shift of nest location of ca. 200-350 m within the same territory occurred and two neighbouring pairs, and nests, were once found at the same time just 400 m from each other. Nest holes excavated by the Dendrocopos major and Picoides tridactylus are often used. On four occasions breeding took place in natural cavities (2x beech, 1x larch, 1x maple). The lowest situated nest was placed lower than one m above ground level and the highest 13 m above the ground. From 44 evaluated nest holes the highest number (26) were situated between 4-7 m. The production of young was evaluated in 57 cases, 34 of which were successful (69.7%). Young were found on 27 occasions, from which 80 fledged: an average of 2.96 per nest. This average is slightly lower than that calculated in Austria and Germany. In the colder than usual years of 2009 and 2010, which were poorer in food availability and characterized by high precipitation, the numbers of fledglings was even lower: on average only 2.3 and 2.0 fledglings per nest respectively. The average number of fledglings per nest from 8 Slovakian nests in three consecutive years (1989 to 1991) was 3.75 fledglings per nest but the same parameter from nine Slovakian nests in six years (2005 to 2010) dropped to 2.88. This indicates a diminishing trend in nest productivity. On one occasion the movements of fledglings in the territory after their fledging were observed for 27 days. On other occasions disturbance due to human activity (tree felling) was recorded as the reason for an abandoned breeding attempt. Such disturbance can be extreme, for example, in the Kysuce Region in the Javorníky Mts and Turzovská vrchovina Mts, two breeding sites with nests in 1999 and 2003 were later destroyed because of complete removal of those forest tracts attacked by bark-beetles. In 2009 in the Strážovské vrchy Mts, a curious case was observed where, during the period of parent care of nestlings, the male disappeared but the female continued to feed her two nestlings alone until they fledged. Just after fledging these fledglings were predated, probably by a Pernis apivorus or an Accipiter nisus, both of which bred nearby. The authors made several remarkable ethological observations in the life of Eurasian pygmy owls. In the Strážovské vrchy Mts the ‘nest-showing’ of more than one cavity in its territory by the male to the female was observed. Copulation was observed a total of eleven times during the months February - May in the years 1989-2010, with the following frequency: February 1x, March 3x, first half of April 5x, second half of April 1x, beginning of May 1x. Interactions of the Eurasian pygmy owls with diurnal raptors, other owl species and other cavity-breeders were also documented. In the Strážovské vrchy Mts the breeding of an Eurasian pygmy owl pair at a relatively close distance to the nests of various diurnal raptors were as follows (species/distance from nest of the raptor from nest of the Eurasian pygmy owl): Pernis apivorus 7 m, Accipiter nisus 230 m, Buteo buteo 250 m, Aquila pomarina 500 m, Accipiter gentilis 700 m. In the Volovské vrchy Mts a pair of Eurasian pygmy owls successfully bred at a distance of 600 m from two nests of Strix uralensis, and another pair bred at a distance of 500 m from a nest of Strix aluco. The breeding of another pair of Strix aluco just 30 m from a cavity used by a pair of Eurasian pygmy owl led to unsuccessful breeding/abandoned nest by this pair. Competitive behaviour was observed between the Eurasian pygmy owl and other cavity-breeders such as Sitta europaea and Dendrocopos major, and an occasion of the predatory killing of an owl fledgling by Strix uralensis was suspected. An attack by Aegolius funereus on a Eurasian pygmy owl was also observed.

AbstractThe landslide susceptibility was assessed based on multivariation analysis. The input parameters were represented by lithology, land use, slope inclination and average annual precipitation. These parameters were evaluated as independent variables, and the existing landslides as dependent variables. The individual input parameters were reclassified and spatially adjusted. Spatial analysis resulted in 15 988 combinations of input parameters representing the homogeneous condition unit (HCU ). Based on the landslide density within individual units, the HCU polygons have been classified according to landslide risk into stable, conditionally stable, conditionally stable and unstable (subdivided into low, medium and high landslide risk). A total of 2002 HCU s were affected by landslides, and the remaining 13 986 were not affected. The total HCU area affected by landslides is about 156.92 km
