Abstract

Urbanization ranks among the primary threats to biodiversity. Birds are a significant group for study in this context, as they respond to the impacts of urbanization and play a role in providing ecosystem services. However, there is still limited knowledge about the responses of birds to the characteristics of neotropical urban landscapes. This study aims to comprehend the key predictors that influence the richness and composition of birds in urban green areas in Campinas-SP, which is part of the Atlantic Forest biome. The 30 sampling points will be determined based on variations in tree and urban coverage, as well as vegetation heterogeneity within a 1-kilometer radius around the points. Data collection will take place during the months of October, December 2023, and February 2024, using autonomous AudioMoth recorders. Each recorder will remain active at the point for 10 days, during the early morning and late afternoon. Species identification will be conducted using the RavenPro 1.6 software. Landscape and local variables (including tree coverage, impervious surface percentage, vegetation heterogeneity, noise, and building height) will be quantified using land-use and land-cover maps, as well as NDVI images at different spatial scales (i.e., a radius around the sampling points, ranging from 50 to 1000 meters); except for noise, which will be derived from the recordings. Generalized linear models will be constructed for each combination of the response variable (richness) and explanatory variable, and model selection will be performed using the Akaike Information Criterion (”AICc). The composition of communities in relation to these predictors will be evaluated through redundancy analysis for binary data, considering the adjusted R-squared value. We aim to contribute to the conservation of urban birds by providing scientific evidence that can support direct landscape planning actions.
