Ecological theory predicts that plant diversity destabilizes local populations, yet empirical studies report variable effects. We hypothesize that this discrepancy arises at least in part from differences captured by different diversity (average vs cumulative richness, i.e. the mean annual richness vs the cumulative richness across years) and stability metrics (abundance‐unweighted vs weighted mean population stability). To test this, we analyzed data from > 8000 permanent vegetation plots across biomes on five continents. We found a negative (i.e. destabilizing) diversity–stability relationship when using abundance‐weighted rather than unweighted measures of population stability, which are more influenced by dominant species. Similarly, cumulative richness – capturing total species occurrence over time and long‐term turnover – reveals a stronger destabilizing effect compared to average annual richness. Our findings reveal that, when specific metrics of diversity and stability are considered, more species and potentially the associated increase in interspecific competition tend to destabilize populations across natural ecosystems world‐wide – particularly those of dominant species. 10.1111/nph.70921 http://creativecommons.org/licenses/by/4.0/ |
