For the established shrubland state, we found that the shrubline was at a m lower elevation in the management units where Rangifer have been browsing in summer as opposed to the migratory ranges with no browsing in summer.
Potential effects of climate change on treeline position in. At treelines across different geographical regions, studies have demonstrated that herbivory can exacerbate or constrain climate-driven distributional shifts in tall shrub and tree species [26,43,  .
Furthermore, trophic interactions should be incorpora ted in modelling vegetation changes as a. Sage beispielsweise eins, zwei, drei oder vier. Also Helle assumed. We also studied if reindeer feeding has an effect on the forage.

|Analyses of 6-year data show that reindeer strongly reduces the growth of tundra willow and changes plant morphology to a stunted growth form.
The sub-Arctic plays a central role in forming the global environment due to the vast territory of boreal forest and tundra. Jiang, L. These results suggest that the species composition and latitudinal limit of the treeline in the future might depend not only on direct effects of the future climate on the current treeline species, but also on the intensity of alien and native conifer introductions as well as changes in herbivore populations.
Thus, species-specific response patterns to a certain climatic event are empirically sustained. Our study supports the proposal that Rangifer management within a sustainable range of animal densities can mitigate the much-focused transition from grassland to shrubland in a warming arctic. The framework defines and characterizes the range of land usage pertaining to animal production, and is suitable for application in land use inventories and scenarios, land cover modeling, and studies on sustainable land use in the past, present and future.

ABSTRACT We developed a nutrient-based, plant community and ecosystem model ArcVeg designed to simulate the transient effects of increased temperatures on the biomass and community,composition of a variety of arctic ecosystems.

Conclusion If sufficient seeds of Norway spruce, Scots pine and Siberian larch should reach the current treeline, their performances will increase with a warmer and wetter climate and this effect will be markedly modulated by herbivores particularly rodents.
