Résumé :

As species functioning is not randomly distributed with respect to phylogeny, we should expect that species assemblages, which are subject to the same environmental filters, often possess a clustered phylogenetic structure. This locally clustered phylogenetic structure is usually detected with randomization tests. In this paper we apply a test of community phylogenetic clustering that takes into account the non-random distribution of species frequency across the phylogeny of the urban flora of Brussels (Belgium). Our results provide only moderate support to the idea that a locally clustered phylogenetic structure is central to the coarse-scale patterns of species co-occurrence of this urban area. The abiotic drivers that promote a locally clustered phylogeny in cities like Brussels are also shortly discussed.
