Sažetak
Small mammals were studied in Dinaric beech-fir forest, their edges, and adjacent meadow in the mountainous region in the central continental part of Croatia. Mammals were collected with pitfall traps along transect extending 60m from the edge into a forest interior and 60m into a meadow, and also along natural and human-induced forest edges. Abrupt edges were created during the construction of the highway, pipeline and transmission lines during different time periods. Therefore, natural process of succession has caused changes in vegetation structure and soil pedological properties, especially in patches of forest clearing. Small mammals were surveyed within the carabid beetle fauna study at 16 sites from April until November 2009. In total, 112 small mammals were captured. Species richness, abundance and diversity were significantly higher along abrupt edges than in the forest interior, which might be caused by the edge effect and particularly higher invertebrate prey offer. Successional changes in oldest clearing patches (under transmission lines) have caused expanding of ecotone and increasing abundance and diversity of small mammals. However, opposite trends were observed in youngest clearing patches (under pipelines), possibly due to scarce vegetation and karstic soil structure, and enhanced predation. Species richness and abundance of small mammals were higher in the forest sites than in the meadow. Abundance and diversity of small mammals vary seasonally in open habitats, most likely due to the vegetation growth causing widening of the ecotone zone.
