Extended Data Table 1 Increase in species richness with time

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

  1. Generalized linear mixed effects models (Poisson family error distribution) show an increase in species richness with time (richness ~ year of record). Different random effect structures were applied. The lower panel includes a breakpoint in the relationship between rate of richness change and time. The breakpoint was fitted independently by minimizing model deviance and was estimated around the year 1970. All models are based on 698 observations. Significant effects are indicated by asterisks (***P < 0.001).
