Extended Data Fig. 2: Species at the lower end, the optimum, or the upper end of their climatic niche.
From: Climate change reshuffles northern species within their niches
(A) temperature, (B) precipitation, (C) snow cover duration, and (D) NAO. All plots show the proportion of species with at least 90% posterior support for the effect of each covariate from the joint species distribution models for each taxonomic group in each sector; bars within sectors represent individual decades. Non-zero responses were classified as “increasing” (yellow), “decreasing” (red) or “bell-shaped” (blue) based on the sign of the derivative of the response over the observed environmental gradient (only linear responses to NAO; see Methods, Scoring species’ position within niche domains). The abbreviations SB, MB and NB correspond to the bioclimatic zones from south to north as shown in Fig. 1; grey circles indicate taxa for which models were not included due to absence of data (for example butterflies in NB), or when a covariate was not modelled (for example NAO for plants).
