Fig. 4: Evaluating the relative contribution of natural factors and anthropogenic threats to species distributions using SHAP values for Alburnoides bipunctatus.
From: Deconstructing the geography of human impacts on species’ natural distribution
a, b SHAP values per sub-catchment for abiotic niche factors that sum to be positive (a) or negative (b). Colours represent the largest contributing abiotic niche factor (discharge, flow velocity, minimum and maximum temperature and distance to the lake). c The qualitative shadow distribution for A. bipunctatus indicating sub-catchments within the abiotic niche but having negative connectivity SHAP values (poor connectivity), negative habitat quality SHAP values (poor habitat) or negative habitat quality and negative connectivity SHAP values (poor connectivity and habitat), as well as no negative SHAP values for threats (blue). Grey indicates areas outside the ecological niche (as in b). d The quantitative shadow distribution for A. bipunctatus shows the ratio between observed suitability and expected suitability, with red indicating a stronger shadow distribution (lower than expected suitability) and blue indicating environmental suitability scores close to expected suitability. Data required to reproduce this Figure is available in Supplementary Data 1 of our Figshare repository86.
