ABSTRACT Global warming is exhibiting a seasonal trend, while different seasons have variations. However, the impact of on plants remains unclear. This study employed Open Top Chambers (OTCs) to simulate future scenarios in alpine meadow. The examined plant community dynamics following long‐term warming. transcriptional and physiological responses two dominant species ( Kobresia pygmaea Stipa purpurea ) were examined. Results suggest that effects are correlated with both duration season which occurs. A long annual duration, especially growing warming, made confront various stresses. K. adopted stress‐avoidance strategy, showing negative response, leading population decline or disappearance. kind dieback had also been observed other Cyperaceae species. Meanwhile, due positive responses, S. stress‐tolerance strategy overcame partially gained dominance over Overall vegetation coverage diversity decreased years. These results reveal plants, explaining reasons for changes communities under providing new insights conservation
