Název v původním jazyce

The role of granivorous rodents in beech forest regeneration in the Beskydy Mt. (Czech Republic)

Popis výsledku v původním jazyce

Forest seed crop, particularly beechnuts and acorns, significantly influence the population dynamics of granivorous rodents negatively affecting the development of forest stands. In seven beech stands of various age and at various altitude, we determinedthe actual food supply for seed--eating species. The average feeding supply biomass in autumn 2007 was 23.23 g . m2. To evaluate effects of seed--eating species on forest regeneration we found out information on the population density of seed--eating species (wood mouse 12 individuals/ha; bank vole 1 ind./ha) but also data on the consumption of forest seeds by the species. Under laboratory conditions, daily consumption of beechnuts was determined for two dominant forest species as bank vole (Myodes glareolus /Pallas/) and yellow--necked mouse (Apodemus flavicollis /Mel./). Our test took 10 days. In M. glareolus (n = 5; mean body mass 21 g), daily consumption ranged from 2.2 to 3.4 g (mean 2.8 g) of beechnuts (seeds of Fagus sylvatica /
