Growing faster, longer or both? Modelling plastic response of Juniperus communis growth phenology to climate change
Abstract Aim Plant growth and phenology respond plastically to changing climatic conditions in both space and time. Species‐specific levels of growth plasticity determine biogeographical patterns and the adaptive capacity of species to climate change. However, a direct assessment of spatial and temp...
