Aim Energy availability is often assumed to be a primary driver of variation in biodiversity across large‐scale environmental gradients such as elevation, but support for the role of energetic constraints is far from universal. Here, we assume that these variations in energy–richness relationships might arise from the degree of match between the scale of the response of organisms to energy (response scale) and the scale of the...

Terrestrial ecosystems are vital for achieving carbon neutrality, yet the distinction between their biophysical limits and realizable potential remains unclear. Here, we developed an integrated framework to quantify China's terrestrial theoretical carbon sequestration potential (CSP) and actual CSP under diverse climate and management scenarios, incorporating vegetation dynamics and soil carbon stocks through 2100. We estimate...

Aim Plastic responses of root productivity to precipitation changes would facilitate plant survival under drought stress. However, whether the responses are pervasive along the soil profile remains unknown. Here, we compiled a global dataset of root productivity at different soil depths from in situ precipitation manipulation experiments, and investigated whether the root productivity responded to precipitation changes uniform...

Aim Drought reduces plant growth and hastens the process of leaf senescence in autumn. Concurrently, increasing atmospheric CO 2 concentrations likely amplifies photosynthetic activity while increasing plant water‐use efficiency. However, how drought affects the date of leaf senescence (DLS) and whether elevated CO 2 can alleviate this remain unknown. Here, we explore the effect of drought on DLS under recent climate change an...
