Bird species richness variation between a habitat types and b in relation to sample coverage; SES of functional diversity variation between c habitat types and d years; and SES of phylogenetic diversity variation between e habitat types and f in relation to sample coverage along rural-urban gradients in central Argentina. SES, standardized effect size; values higher than zero indicate a greater diversity than expected by the null model, whereas values lower than zero indicate lower diversity than expected by the null model. Points are means, and vertical lines and grey areas are confident intervals
