Here we provide an unequivocal evidence of syntopic occurrence of the garden dormouse (Eliomys quercinus) and the edible dormouse (Glis glis) in a talus habitat in the montane climax spruce forest (Piceion abietis: Calamagrostio villosae-Piceetum) in the Bohemian Forest (Czech Republic). Whereas the garden dormouse has been regularly recorded within spruce stands throughout Central Europe, presence of the edible dormouse in the coniferous woodland is unusual and therefore discussed. At the locality both dormouse species shared not only the same macrohabitat, but also the same vertical niche and, moreover, utilized identical trophic resources. Their diet consisted of ripe bilberries (Vaccinium myrtillus) and arthropods (especially spiders). Finally, factors enabling the syntopic occurrence of the garden and edible dormice are discussed.
