Scale-dependent effects of urbanization on avian diversity in a Neotropical region

RDA_birds script: This is the script that contains the Redundancy Analysis (RDA), whose database is named: "Rda_birds.txt". RDA is a multivariate statistical technique that combines elements of Principal Component Analysis (PCA) and Multiple Regression to explore the relationships between sets of variables. This technique is often used to analyze data where there are multiple responses (dependent variables) and multiple predictors (independent variables). In this case, we used this statistical technique to explore multivariate relationships between sets of variables, where we explored how local environmental and landscape characteristics (independent variables) can explain patterns in bird species communities (dependent variables).

MOBr_birds script: This is the script that contains the Biodiversity Measurement Analysis (Mob), whose database is named: "Mobr_birds". Mob is a multi-scale approach to dissecting the roles of species abundance distribution (SAD), total community abundance and spatial aggregation within species along continuous environmental gradients.
