Differential impact of hotter drought on seedling performance of five ecologically distinct pine species

Increasing temperature and drought intensity is inducing the phenomenon of the so-called ''hotter drought'', which is expected to increase in frequency over the coming decades across many areas of the globe, and is expected to have major implications for forest systems. Consequen...
