Mapping climatic mechanisms likely to favour the emergence of novel communities [Nature Climate Change]

par Frédéric Magné - publié le

Climatic conditions are changing at different rates and in different directions potentially causing the emergence of novel species assemblages. Here we identify areas where recent (1901–2013) changes in temperature and precipitation are likely to be producing novel species assemblages through three distinct mechanisms : emergence of novel climatic combinations, rapid displacement of climatic isoclines and local divergences between temperature and precipitation vectors. Novel climates appear in the tropics, while displacement is faster at higher latitudes and divergence is high in the subtropics and mountainous regions.(...)
