Dormice (Gliridae) in the diet of predators in Eurasia: a review
Dormice are widely distributed through Eurasia and Africa, but their abundance varies considerably. In many regions, dormice are rare, and their role in ecosystems is considered to be unimportant. The aim of this study was to evaluate the significance of dormice in the diet of predators in the Palae...
