    Mapping of the Eurasian otter (Lutra lutra L.) in the Hron River basin (Slovakia)
    (Brno : Ústav biologie obratlovců AV, 2025) Urban, Peter; Hrdý, Tomáš
    Hron is the second longest river in Slovakia. It springs under Kráľová hoľa at an altitude of 934 m and flows into the Danube not far from the place where the Danube leaves the territory of Slovakia. Mapping the river otter in a square grid is, despite the reservations, a method used to determine the spread of this species over a relatively large area and its changes. The distribution of the otter in the Hron river basin was investigated during five field mappings (winter 1995/1996, summer and autumn 2010, winter 2011/2012, winter 2021/2022, winter 2022/2023) using a modified IUCN/OSG standard method. It was about the evidence of the presence of a species, or its residence signs on selected 600 m sections of streams in the network of 48 squares of the Databank of the Fauna of Slovakia (approx. 10 × 12 km) and their 150 quadrants (approx. 2.5 × 3 km). During the first mapping in the winter of 1995/1996, the lowest number of positive squares (35; t. j. 72,9 %) and quadrants (71; 47,3 %) was recorded. Signs of otter habitat were mainly absent in the lower reaches of the Hron, but they were found near its mouth into the Danube, or on some tributaries of the lower Hron (e.g. Paríž). During further mapping, there was an increase in both positive squares and quadrants in the entire river basin. The increase was most pronounced in the middle and lower part of the basin. The highest number of positive squares (46; 95,8 %) and quadrants (125; 83,3 %) was recorded in the winter of 2021/2022.

    Natural and anthropogenic factors influencing the Tatra chamois (Rupicapra rupicapra tatrica) in the Nízke Tatry (Low Tatras) Mts. (Central Slovakia)
    (Faculty of Environmental Protection : Velenje, 2025) Hrdý, Tomáš; Hronček, Pavel; Hrončeková Gregorová, Bohuslava; Urban, Peter
    European roe deer (Capreolus capreolus) is the most widespread wildlife species in Germany and therefore a subject of hunting in nearly all habitats. Due to its importance, forest owners and hunters are interested in successful hunting regimes, which depend on their respective objectives. However, objectives of forest owners and hunters are not always in accordance and sometimes even oppositional. Hunters are often confused by old traditions and beliefs. Furthermore, hunting regimes often contradict current scientific knowledge of wildlife biology and ecology – as well as the hunters’ objectives. In addition, most forest owners are not educated in forest sciences and thus do not have sufficient knowledge of silviculture, forest products, and forest damage in their ownership. The goal of this contribution is to compare different trials of hunting regimes taking into account recent scientific studies and to present conclusions for wildlife management and roe deer hunting.
