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...

Grassland ecosystems play essential roles in global carbon cycling and biodiversity conservation, yet it remains unclear whether belowground productivity is less sensitive to environmental change than aboveground productivity. Previous studies have predominantly focused on aboveground net primary productivity (ANPP) stability, potentially overestimating ecosystem vulnerability by neglecting critical belowground processes. By s...

Non‐structural carbohydrates (NSCs) and nitrogen (N), phosphorus (P) facilitate the adaptation of trees to drought stress. There have been a large number of individual studies exploring NSCs and N, P changes in leaves, stems, and roots of different tree species during drought; however, an understanding of the general pattern across organs and interactions of NSCs and N, P responses to drought is still lacking. Here, we compile...
