Abstract
Extensive experimental and theoretical evidence demonstrates the positive effects of plant diversity on the temporal stability of productivity, yet how the diversity-stability relationship varies across timescales and different diversity dimensions in natural ecosystems remains unclear. By integrating a comprehensive regional vegetation survey conducted in Tibetan alpine grasslands with the global plant diversity and productivity databases, we revealed a consistent temporal pattern at regional and global scales: the stabilizing effect of plant diversity on productivity strengthened over time, approaching saturation at 10 to 13 years. Notably, plant phylogenetic diversity emerged as the dominant biotic driver of long-term stability. In contrast, plant community height exerted a stronger positive influence on short-term stability. These findings highlight the critical role of timescales in shaping diversity-stability relationships and underscore the necessity of decadal-scale studies. Our results further support integrating phylogenetic diversity into conservation and management strategies to sustain ecosystem functioning under global change.
