Figure 3From: Habitat productivity constrains the distribution of social spiders across continents – case study of the genus StegodyphusProbability that a Stegodyphus occurrence records belongs to social species as a function of vegetation productivity. The probability function was estimated by a logistic regression with vegetation productivity and spatial filters as predictors (Table 1). The line indicates a response curve estimated by smoothing the probabilities predicted by the vegetation productivity + spatial filters model.Back to article page
