High-resolution Light Detection and Ranging (LiDAR) scanners provide detailed information on terrain surfaces, thus enabling the detection of the topographic signatures of historical anthropogenic landforms overgrown by trees or covered by the soil surface. This study aimed to examine the potential of incoming nationwide LiDAR data for detecting the cultural landscape features in Slovakia. We derived a detailed digital elevation model from LiDAR points and adopted upgraded visualisation techniques based on the combination of local relief models, sky view factor, slope steepness, and colour blending. We visually identified examples of different anthropogenic landforms and confirmed our findings with existing literature. In addition, we provide examples of previously unknown historical anthropogenic landforms discovered from LiDAR images. Finally, we discuss the potential and limits of LiDAR data in exploring and protecting different groups of historic anthropogenic landforms as remnants of past cultural landscapes in Slovakia.
The spiders Walckenaeria stylifrons (O. Pickard-Cambridge, 1875) and Spiracme mongolica (Schenkel, 1963) are reported from Slovakia for the first time. These new records are based on adult males found in Western Slovakia in xerothermic habitats. The occurrence of W. stylifrons in Slovakia fills the gap in its distribution in Pannonian Basin and between Austria and Ukraine. Spiracme mongolica has been known only from the Balkans and south-eastern part of Europe to central Asia, this is the first record for Central Europe. We suggest Spiracme mongolica (Schenkel, 1963) new combination for Xysticus mongolicus Schenkel, 1963. Characteristic features, photographs of habitus and copulatory organs, and habitats of the new records are presented.
Tegenaria hasperi Chyzer, 1897 (Agelenidae) and Zoropsis spinimana (Dufour, 1820) (Zoropsidae) are recorded in Slovakia for the first time. Both species were collected in synanthropic habitats in Western Slovakia. Two males of T. hasperi were collected in the garden of a family house, and both sexes of Z. spinimana were recorded from the interiors and exteriors of buildings in four separate cities, representing the first record of the family Zoropsidae in Slovakia. This contribution provides additional information on the morphological characteristics of these species. Digital images of their habitus and copulatory organs, as well as their distribution and habitat preferences are included.
The aim of our study is to reconstruct the human influence on the current vegetation in selected parts of the cadastral territory of Svätý Jur. Svätý Jur is a town with more than 700 years of winemaking tradition, located on the oak-hornbeam-forested slopes of the Little Carpathians and surrounded by terraced vineyards. Human activity has changed the natural landscape of Svätý Jur since the Neolithic period. It is possible to trace the influence of past human activities on current vegetation by mapping vegetation onto historical landscape structures. For our research, we chose two study sites—Biely Kameň Castle and Hillfort Neštich. Our research has shown that there are significant differences in plant communities as well as in their environmental requirements between the investigated sites. Nitrophilous species indicative of human activities were recorded at both sites. At Hillfort Neštich, we recorded the occurrence of an interesting combination of species of Atropa, Phytolacca and Rubus. We have recorded their current occurrence and searched for its causes. In addition, we evaluate the current state of the vegetation of the castle and the hillfort in relation to the human past and today’s use.
