What does this research mean for the field?

Bird species richness, abundance, and evenness in urban parks are independently driven by both patch-scale and landscape-scale factors, with landscape-level tree and grass cover being consistently important predictors. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To assess how patch-scale vegetation structure, human disturbance, and landscape composition and configuration associate with bird abundance, diversity, and assemblage evenness in urban parks.

Overview

Ecological study reveals multiscale environmental drivers of bird diversity in urban parks, indicating distinct assembly processes shape species richness and abundance.

Key Points

To assess how patch-scale vegetation structure, human disturbance, and landscape composition and configuration associate with bird abundance, diversity, and assemblage evenness in urban parks.
Sampled bird assemblages across 20 urban parks in Mexico City, recording a total of 1,194 individual birds representing 56 species.
Quantified patch-scale vegetation structure and human disturbance alongside landscape-scale composition and spatial configuration metrics.
Tree and grass cover at the landscape scale positively associated with species richness, but negatively associated with total bird abundance and assemblage evenness.
Greater isolation of tree cover patches correlated positively with species richness and assemblage evenness, while greater inter-tree distance within parks correlated negatively with bird abundance.
Bird communities were dominated by a few synanthropic species, showing that species richness, abundance, and evenness respond independently to distinct multi-scale assembly processes.
