Figure 1: Biotic specialization in relation to climatic niche breadth and vulnerability to climate change.
From: Ecological networks are more sensitive to plant than to animal extinction under climate change
Associations of (a,b) realized climatic niche breadth (climatic hypervolume60, OMI climatic niche breadth61) and (c,d) projected climatic suitability change (RCP 6.0, RCP 8.5 scenarios65; year 2070) with the effective number of partners (eH) of plant (n=295) and animal (n=414) species in 13 mutualistic interaction networks from central Europe. Specialization is the effective number of interaction partners66 of plant (blue) and animal (red) species in each network (shown on a log-scale). Trend lines indicate the estimated slope (β) in a mixed-effects model accounting for effects of network identity and animal and plant taxonomy on model intercepts. Shown are species’ mean partial residuals plus intercept from these models; symbol size is proportional to the weight of each species in the analysis, corresponding to its number of occurrences across networks and, in the case of climatic suitability change, the accuracy of the species distribution model (TSSmax value64); given are slope estimates±1 s.e. for plants and animals, P values were derived by Kenward–Roger approximation: **P<0.01 and ***P<0.001 (for full statistics see Supplementary Table 1).
