Materials of garden dormouse summer nests in Germany

Nesting is a central topic in the behavioural ecology of many species, but data on the materials used to construct mammal nests are rarely reported. This paper describes the most commonly used components from 25 summer nests of the garden dormouse, a small threatened rodent endemic to Europe. Median nest dry weight of 25 nests was 15.5 g (10.3–21.1 g) and moss was the most common material (78 %), followed by leaves (9 %). Mosses were also the most frequently used material, with Hypnum cupressiforme being the most frequently used taxon in 11 out of 25 nests.
