Socio-economic status and non-native species drive bird ecosystem service provision in urban areas

Areas of higher socio-economic status within urban areas generally have higher levels of taxonomic diversity than poorer areas, representing a form of environmental injustice. This inequality may result in lower-income areas experiencing both lower cultural (e.g., non-material services provided by bird aesthetics) and regulating (e.g., pest control by insectivorous birds) ecosystem service provision. Furthermore, urban areas are hotspots for the introduction of non-native species, which can potentially alter the functional space of invaded communities, and hence their ecosystem service provision. However, the relationship between socio-economic status and the ecosystem services that both native and non-native urban biodiversity provide has yet to be fully addressed. We tested whether functional diversity associated with avian cultural and regulating ecosystem services varied along the socio-economic gradient of functional urban areas (FUAs) in the Iberian Peninsula. We used bird atlases..., , # Socio-economic status and non-native species drive bird ecosystem service provision in urban areas

## Description of the data and file structure

This repository contains data and scripts used in the analyses of functional diversity and corrected functional dispersion (CFD) of birds in Spanish and Portuguese urban areas. Traits list, community matrices, and income data are included, along with the R scripts used for CFD calculation and statistical modeling.
