Potential Temporal and Spatial Responses of Forest Communities to Climate Change: Application of Two Simulation Models for Ecological Risk Assessment
1993
Kienast, F. | Brzeziecki, B. (Swiss Federal Institute for Forests, Snow and Landscape Research, Birmensdorf (Switzerland))
Two modeling approaches were applied to evaluate the potential risks of increasing atmospheric carbon dioxide concentrations and possible climate change on the vegetation cover of the Alpine region. The first model is a stochastic forest succession simulator, the second is a static regression type model. The questions of the study were as follows: (1) Which temporal vegetation changes might occur under given carbon dioxide and climate scenarios? (2) Which region of the Alps might be most susceptible to a vegetation change?

1993
Kraeuchi, N. (Swiss Federal Institute of Technology, Zurich (Switzerland))
The ranges of the ecosystems move when the climatic pattern changes. Simulations have shown that a global warming would cause important changes of the species composition in subalpine forests. Deciduous trees would invade today's subalpine belt. Various conifers would be displaced and migrate into alpine zone. The model simulations are based on the IPCC climate scenarios.
