Model and parameters of urban biodiversity (tree and bird species richness) and vegetation cover (% per neighbourhood) in response to: high educational attainment (% of the population with high education attainment by neighbourhood over the total population, proxy of luxury effect), neighbourhood development age index (values ranging from 0 – newest to 1 – oldest), habitat quality index (values ranging from 0- lowest to 1- highest), population density (inhab/ha), vegetation cover (only for biodiversity), and interactions of high educational attainment with habitat quality and neighbourhood age with population density. Model formula for each predictive variable, adjusted variance explained (R²), F-statistic (F), significance level (p) and standard error (Std. Error). N = 28, n.s.: non-significant.
