Opposing shifts in distributions of chlorophyll concentration and composition in grassland under warming

Abstract Global warming has significantly altered the distribution and productivity of vegetation owing to shifts in plant functional traits. However, chlorophyll adaptations—good representative of plant production—in grasslands have not been investigated on a large scale, hindering ecological predi...
