We show how secondary roads may affect landscape permeability for brown bears (Ursus arctos Linnaeus, 1758). We focused on identifying environmental variables that govern the selection of road-crossing zones by bears (crossing model). We also investigated whether variables that characterize road-crossing zones differ from those that are typical for bear–vehicle collision sites (collision model). The study area was located in north-central Slovakia. To identify road-crossing sites, we used the GPS fixes of 27 bears and identified 35 bear–vehicle collision sites from a different data set. We used mixed-effects logistic regression to model resource selection at road-crossing sites and to compare bear-crossing sites with bear-kill sites. The crossing model showed that the traffic volume with distance to forest and grassland were the most influential factors in bear selection of road-crossing sites. Results of the collision model indicated that successful road crossings by bears were located at different road sections from vehicle collisions, which differed by a traffic volume of 5000 vehicles/24 h. The outcomes of this study can facilitate improved mitigation measures on secondary roads.

Disperser benefits may be direct, by using the dispersed plant species as a food source, and indirect, by promoting the distribution of these food plants. Despite biomass loss involved, plant species may benefit from endozoochory, because it promotes long-distance dispersal and linked advantages. We tested this mutualism hypothesis in the Poľana Biosphere Reserve, central Slovakia, with red deer (Cervus elaphus) as disperser. We collected data on distances covered by red deer between seed ingestion and excretion sites, and the corresponding vegetation by VHF telemetry and GIS analysis. We assessed the viable seed content of red deer dung by a germination test. Information on forage palatability, habitat and seed longevity of the dispersed species were taken from literature. From a total of 400 g dry red deer feces, 1766 seedlings emerged, belonging to 43 species. Most of the observed dispersal distances exceeded 100 m, which is commonly considered as a minimum for long-distance dispersal. Red deer transported mostly seeds from a variety of vegetation types to forests. Our results support the hypothesis that endozoochory is a mutualistic process. We conclude that, since landscapes are changing due to global warming and land use changes, it is important for the maintenance of plant species diversity to promote migration and free ranging of large grazers like red deer, by means of infrastructural measures.

However, diverse human activities are in potential conflict with the conservation of large carnivore species. We discuss the role that hunters have in the management of three large carnivore species, the brown bear Ursus arctos, the Eurasian lynx Lynx lynx and the wolf Canis lupus in the Carpathian Mountains in central Europe. We considered four different countries (i.e. Poland, Slovakia, Ukraine and Romania), comparing the status of large carnivore populations and the regulations of hunting activities. The situation appears to be generally consistent throughout the Carpathian region, although the degree of protection accorded to wolf varies most. Interactions between large carnivores and hunters are well rooted in the culture of local communities in the four countries considered. The large forested areas make the Carpathians an excellent environment for large carnivores, which here are favoured by low human population density. We underline the need for integration of hunting activities and scientific knowledge for future management practices.

The study was carried out in 1994-2002 in two national parks of central Slovakia. In the Tatry National Park we monitored for 11 months an adult male associated with a pack of 7. In the Nizke Tatry National Park we radio-tracked an adult female for 82 months (1995-2002). Over the course of the study the pack size in the Nizke Tatry ranged from 2 to 7 members. In this park the most intensive telemetry was conducted from 1996 to1997 when the radio-tagged female reared her offspring. Home - ranges of radio-collared wolves calculated for the whole period of radio - tracking (MCP with 100 % of observations) were 146 km 2 (male) and 191 km 2 (female), respectively. Extraterritorial forays were not observed. Core areas of the home - ranges estimated by the Kernel method (50 % of locations), were small (21 km 2 : male; 28 km 2 : female) and overlapped mainly with the forest habitats heavily used by red deer (Cervus elaphus). The size of territory used in summer was 24 % - 49 % smaller than in winter.
