Effects of crop diversity and landscape heterogeneity on bird richness.

Landscape effects on total bird richness.
Effects of a) landscape-level crop diversity (CropDiv) and b) perennial habitat diversity (LandHet, proxy for overall landscape heterogeneity) on total species richness. Exemplified for landscape effects at the 3000 m scale (lowest AICc value) with predicted values for each study site (n = 14). Regression line and 95% confidence intervals shown.
Fig 2.
Habitat diversity effects on functional group richness.
Effects of perennial habitat diversity (LandHet, proxy for overall landscape heterogeneity) on species richness of the functional groups a) feeding guild (2000m scale), b) conservation status (250m scale), c) habitat preference (1000m scale), and d) nesting behaviour (farmland bird subset, 250m) shown for scales with lowest AICc values. Slopes were tested against zero using contrast matrices with p-values adjusted for the False Discovery Rate ([45], S3 Table). Shown are fitted lines and 95% confidence intervals. Signifance levels: *** p<0.001, * p<0.05.
