  abstract = {{U}rbanization induces changes in species abundance and richness that are beginning to be extensively described. {H}owever, the functional structure of urban communities still requires attention to provide a basis for a more accurate understanding of urban ecosystems' functioning. {T}his study has been performed in order to assess functional changes in ecological communities related to changes of urban landscape features along an urbanization gradient. {S}pecies abundance and richness of birds and butterflies in the city parks of {M}arseille (south-east {F}rance) have been used to assess these changes. {O}n the basis of easily accessible traits (reproduction parameters, size, feeding habits), we have examined whether different contexts of urbanization favour some strategies more than others. {S}ome differences occur between butterflies and birds in terms of species abundance and richness through the urbanization gradient, showing that at least some species of birds manage to colonize city centre and/or exploit urban resources better than butterflies. {B}ut our results also clearly reveal general patterns in biological traits for both birds and butterflies that further reflect the gradient of urban features from outskirts to city centre. {S}pecies associated with the city centre tolerate a wide range of conditions whereas species associated with city outskirts have more specialized abilities. {U}rbanization acts as an environmental filter for bird and butterfly communities selecting species able to colonize and settle in the city centre on the basis of their biological traits. {I}n our context, environmental filters induce a biotic homogenization with urbanization through loss of species (taxonomic homogenization) and over-representation of generalist species (functional homogenization). {T}his homogenization reflects an underlying process of disruption of biotic interactions for butterflies and birds. {T}his study has enabled us to identify a combination of biological traits sensitive to urban features that may represent useful indicators for both theoretical and applied purposes in order to understand the impact of urbanization on animal communities.},
