Extended Data Table 7 Trait differences between colonizing and old-established species

From: Accelerated increase in plant species richness on mountain summits is linked to warming

  1. Linear mixed effects models (Gaussian family error distribution) revealed systematic trait differences between colonizing and old-established species. Analyses were implemented for 364 resurveys (12,738 observations with 815 species) with a random effect of resurvey. Temperature indicator values49 were available for 90%, specific leaf area (SLA)48 for 61%, plant height48 for 76%, and seed mass48 for 53% of the observations. Significant effects are indicated by asterisks (***P < 0.001). Trait raw data were first log-transformed, then centred to zero mean and scaled to s.d. = 1 before analysis.
