Nitrogen addition reduces alpine grassland stability via enhanced temporal synchrony and population variability

Puntos clave

• Alpine grassland stability decreases with nitrogen addition, impacting ecosystem resilience.
• Temporal synchrony and population variability were significantly affected by nitrogen treatments, revealing a 30% decrease in stability.
• Assessment of grassland ecosystems across multiple regions highlighted the ecological impacts of nitrogen exposure.
• These findings may imply significant risks for biodiversity, warranting further investigation in diverse ecological contexts.
