(A–D) Current and future climatic niches of Dactylorhiza hatageria. The correlation circle represents contribution of bioclimatic variables to the first two components main of the PCA-env analyses and the percentage of variation explained by each axis. The blue and red shadings represent density of species occurrence under current and future climatic scenarios. The bar plots represent the results of niche equivalency and similarity tests. The red arrow represents the shift in the climatic niche between current and future climatic conditions.
