The net outcome of the population dynamics processes of growth, mortality and regeneration is change in species composition as a consequence of a changing climate. In the Amazon forests, dry habitat- affiliated genera have become more abundant among the newly recruited trees, while the mortality of moist habitat-affiliated genera has increased in places where the dry season has intensified most, thus driving a slow shift towards a drier forest type . A similar multi-decadal shift in West-African forest species composition towards more dry-affiliated species as a response to long- term drying has been recorded . While upward shifts in the tree line and in the range of individual tree species have been recorded at several temperate mountain regions, evidence from the tropics is rare. A large-scale study from 200 plot inventories of >2000 tree species across a ~3000 m elevation gradient in the Andean tropics and sub-tropics has shown that the relative abundances of tree species from lower, warmer locations were increasing at these sites indicating that 'thermophilisation of vegetation'  was indeed taking place as expected  .
