Home range and migration patterns of male red deer Cervus elaphus in Western Carpathians

摘要

This study provides for the first time in the Carpathians analysis of spatial behaviour of 20 male red deer monitored during 2005-2013 using radio-telemetry. Two distinct spatial patterns were displayed in the same local population, i.e. residential and migratory. Residential annual home ranges were significantly smaller compared to migratory ones using both Minimum Convex Polygon and Kernel Home Range, due to periodic movement of migrants between distinct seasonal ranges. Residents remained in the same area throughout the year and showed a positive age effect on the home range size. While seasonal ranges of migrants were comparable in size, residents surprisingly expanded their space use in winter compared to other seasons. Fidelity to seasonal ranges over the years, especially winter, was striking and comparable in both migrants and residents with increasing tendency throughout the year (37-68 %). Vertical differences in home range altitudes were most obvious in migrants, although in both migrant types, significant descent was recorded during the winter. The longest horizontal movements were recorded in three young stags emigrating to neighbouring mountain ranges (30, 47 and 65 km). Because 45 % of the population seems to be migratory, the data support importance of large-scale hunting management established in Slovakia in 2009.
