The aim of the study was to characterise the problem of road accidents involving selected species of wild-living animals present in the area of Lublin. Another aim of the investigations was to determine the relationship between selected behavioural elements of the annual life cycle of animals and the incidence of wildlife-vehicle collisions. The information about wildlife-vehicle collisions was obtained from the documentation held by the shelter for homeless animals in Lublin and veterinary services. The data are presented in a spreadsheet and analysis was performed in the GIS (ArcGIS 10.1) environment. Based on the ESRI Base Map-BING MAP HYBRYD, a vector database of streets where the incidents had taken place was compiled. Each street was assigned the number of incidents recorded in the period of 2009–2012. Animals were divided into three groups: large mammals, small mammals and bats. The compiled data indicate the highest road mortality among roe deer (132), foxes (63), and martens (33). The reported results show the greatest number of wildlife-vehicle collisions on exit roads leading from the city centre. Presumably, this may be associated with the lack of speed limits and possible faults in the infrastructure arising already at the design stage.
In 2005–2008, we radio-tracked 17 foxes in rural areas of Southern Germany. The mean home range size was 76.6 ha (95% MCP) or 138.9 ha (95% fixed kernel), and the built-up area formed an integral part of the home range. Home ranges of juvenile foxes were significantly smaller than home ranges of adult foxes. Gender-specific differences among adult foxes were not established. A minimum population density of 2.7 foxes per km2 and summer densities of up to 13.4 foxes per km2 were calculated. Therefore, the fox density was three to eight times higher than that of strictly rural foxes. Daytime resting sites of foxes were mostly found in forests (62.2%) and reedbed areas (20.6%). Of the resting sites, 14.8% were situated inside settlements, in fallow gardens or gardens of residents. During the day, foxes exhibited habitat preferences for forests and reedbed areas. A habitat structure that offers plenty of cover or dense vegetation is essential for its selection as a safe resting site. If this basic requirement is fulfilled, foxes also choose resting sites within settlements, and are not disturbed by human presence.
Trichinellosis is one of the most frequent parasitic disease in Poland. Up to now, all animal and human trichinellosis infections in Poland have been considered to be caused by Trichinella spiralis in spite of only few isolates from humans and swine have been identified so far. From November 1994 to February 1995, 112 mammals belonging to 9 species were examined to detect Trichinella infection, and to identify the etiological agent at the species level. Muscle larvae of Trichinella sp. were isolated from 3 (27%) red foxes (Vulpes vulpes), 3 (13%) common shrews (Sorex araneus), and from 2 (20%) pygmy shrews (Sorex minutus). Only larvae from foxes have been identified by random amplified polymorphic DNA analysis as T. spiralis and T. britovi in one and two animals, respectively. As far as we know, this is the first report of T. britovi in Poland.
