In particular, the trait coordination was characterised by the maintenance of net photosynthesis rate and the increase of total leaf area, which was robust across ecological contexts although warming responses of the variables per se displayed context-dependences. Moreover, the trade-offs between biomass and reproduction (itself bearing mass vs. number trade-offs) in their warming responses scaled the coordination to enhance fitness except in the contexts where reproduction was reduced.

Using a global database, we computed an index of urban success for 1287 bird species and quantified its association with estimates of plumage colour. Our analyses showed that birds that do well in urban environments are more likely to be blue, dark grey and black, and less likely to be brown or yellow. After considering phylogenetic relatedness, only the effects of yellow and brown remained significant. Species with high urban success also exhibit more elaborate colours, but not higher sexual dichromatism. We provide eco-evolutionary explanations for these results.
