What drives tree recruitment at alpine tree lines?

Valentin Graf, Senckenberg Biodiversity and Climate Research Centre in Frankfurt, discusses his article: Relative importance of range position, seed size, and genetic diversity for tree recruitment at alpine range edges Climate change is rapidly altering ecosystems, pushing many species to adapt or move to cooler environments. In mountains, this often means shifting to higher elevations,…

Martin Girardin on Mapping trees’ climate sensitivity: Evolutionary dynamics explored using tree rings / Cartographie de la sensibilité climatique des arbres : Dynamiques évolutives explorées à l’aide des cernes de croissance des arbres

Background The way that tree species develop and change over time is affected by the climate they live in. In the vast expanse of Canada’s terrestrial ecosystems, nearly 180 tree species have undergone selective processes since the last glaciation, sculpting their evolution and establishment. Climate emerges as the linchpin, steering the destiny of tree populations…
