Home ranges and movement patterns in a vulnerable polecat Mustela putorius population

tom 49

nr 2

Home range characteristics and movement patterns of four female and six male polecats Mustela putorius Linnaeus, 1758 were studied in Luxembourg using radio- -telemetry. Home range size of polecats ranged from 42 to 428 ha with an average of 181 ha. The mean (± SE) home range size of males of (246 ± 45 ha) was significantly larger than that of females (84 ± 17 ha). Polecats concentrated 50% of their space use in only 15% of their home range possibly indicating a patchy .environment. Comparing our data with other studies in Europe, polecats seem to occupy approximately the same home range size (except in Switzerland) regardless of population density. Average distance traveled per night by males was 3.6 times greater than that of females. Also, seasonal variation in movements was observed in males but not in females.

The polypore fungus Spongipellis spumeus is red-listed in Poland and in several other European countries. On the basis of published data and seven new locations, we have presented its distribution in Poland. In the country, S. spumeus was recorded primarily in anthropogenic habitats (tree lines along streets and roads, old orchards, parks), and rarely in forest communities. Two tree species (Acer platanoides, Populus alba) is reported here as a new host of S. spumeus in Poland. The declining acreage of alluvial forests and removal of old trees from substitute habitats (e.g. parks or avenues in cities) seem to be major threat factors for this fungus. Based on the new distribution data for S. spumeus in Poland, it should be rather classified as vulnerable (VU) according to IUCN red-listed criteria, than endangered (E) as it currently is. One beetle species i.e. Tetrotoma fungorum was found on the basidiomata of S. spumeus during the study, that may imply the role of the beetle in spreading of this fungus.
