Figure 4From: Habitat productivity constrains the distribution of social spiders across continents – case study of the genus StegodyphusInsect biomass as a function of (a) vegetation productivity, and of (b) precipitation seasonality. Annual and seasonal insect biomass estimates from the study region are plotted on the vegetation productivity and precipitation seasonality gradients, with the line in (a) showing the significant partial coefficient estimates for vegetation productivity from mixed model effects with log insect biomass as a response (Table 3), with vegetation productivity, precipitation seasonality and taxon as fixed; and sampling effort as a random effect.Back to article page
