Overview

Experimental analysis shows varying species responses to precipitation changes and nitrogen enrichment in grassland communities, suggesting genome size mediates these outcomes.

Key Points

  • Species with small genome size exhibited greater drought tolerance, influencing community productivity during dry conditions.
  • Large genome size species responded better to wetter and nitrogen-rich conditions, indicating a link to their higher nutrient demands.
  • The research combined precipitation and nitrogen addition experiments in a semi-arid grassland to uncover these dynamics.
  • Ecosystem responses to environmental changes may be clarified through understanding stable genetic characteristics like genome size.
