- Abstract:
- Rodent population dynamics and the influence of weather were studied in the old growth mountain forest „Rothwald“, in the Wilderness Dürrenstein of Lower Austria. This master-thesis “Populationsdynamik von Apodemus flavicollis und Myodes glareolus im Wildnisgebiet Dürrenstein – Saisonale Schwankungen und Witterungseinfluss” (Population dynamics of Apodemus flavicollis and Myodes glareolus in the Wilderness Dürrenstein – Seasonal changes and the influence of weather) is part of a long-term study of the Institute of Wildlife Biology and Game Management of the University of Natural Resources and Life Science, Vienna. The start of the small mammal long-term study was 2002. Small mammals were trapped alive in June, August and October 2014 on five different study plots, i.e. two late-successional old growth plots, one early-successional plot in the old growth forest area (avalanche 2009), a windthrow from 1990 and a managed forest. Using a mark-recapture method seasonal changes in capture success of yellow-necked mouse (A. flavicollis) and bank vole (M. glareolus) were estimated. I also investigated how the activity of these two species changes with weather conditions. The five sample plots showed different development between the seasons and over the year. A. flavicollis was the dominant species on all five plots and in every season. While capture success of yellow-necked mouse tend to increase during the year, numbers of bank vole seem to be in decline. Rainfall positively influenced the activity of small mammals on the windthrow and on one plot in the late-successional old groth forest. Negative influence of rain was detected on the early-successional plot where there is no closed canopy.
