Nicholas P. Danz, Lee E. Frelich, Peter B. Reich and Gerald J. Niemi Do vegetation boundaries display smooth or abrupt spatial transitions along environmental gradients? Evidence from the prairie–forest biome boundary of historic Minnesota, USA Journal of Vegetation Science 24
We use data from a historical grassland-forest biome boundary to show that forest vegetation responds in a non-linear or threshold manner to comparatively gradual spatial changes in climate. Thus, modest climatic changes may have potential to cause substantial locational shifts in this biome boundary.
