Dynamik von Kleinnagern und deren Beeinflussung durch Hochwasser in mitteldeutschen Auwäldern
[Abundance dynamics of small rodents and flood influence in floodplain forests in Central Germany]
Small rodents were investigated in some floodplain forests in Central Germany. The small rodent communities mainly consisted of the yellow-necked mouse Apodemus flavicollis and the bank vole Clethrionomys glareolus. These two species represent more than 90% of all individuals of the community. The longterm fluctuations occurred irregulary in all species. The population densities after floods were very low and dominated by A. flavicollis. The small rodents had better survival chances by swamps with pressure water from the underground. The trees and shrubs can be considered as survival locations for small rodents.
