Top: Bounds of the absolute corridors of temperature (coldest month of the growing season) and annual precipitation for growing walnut trees in Western Tajikistan (vertical lines), temperature and precipitation relations to elevation (red and blue splines, respectively) and the corresponding elevation range (marked on the vertical axis). Left for present-day, right for 17 GCM projections of the 2061-2080 conditions (WorldClim, RCP8.5 scenario of strong climate change). Bottom: maps indicate where the temperature and precipitation requirements according to the absolute climate corridors are met (left for present-day, right for the future conditions; colours indicate the number of GCMs)
