Spatial fingerprints of climate change on biotic communities are usually associated with changes in the distribution of species at their latitudinal or altitudinal extremes.

In China both an increase in the lower altitudinal limit of mountain permafrost and a decrease in areal extent have been observed (Wang et al., 2000).

Trees growing near to the latitudinal or altitudinal treeline are mainly under growth limitations imposed by temperature and hence ring - width variations in such trees contain a strong temperature signal.

Growth rates are sensitive to many things, this is why so much care is taken to select samples that one might rightly suspect will be highly sensitive to temperature changes (such as trees growing near their altitudinal and latitudinal range extremes, which typically is due to the species limit of cold tolerance).
