'urbanisation croissante des dernières décennies a conduit au développement de nouveaux habitats aménagés par l'homme en milieux urbains tels que les espaces verts publics et privés. Ces habitats font l'objet d'introductions d'espèces végétales, sources potentielles d'espèces invasives, dont les impacts sont actuellement reconnus comme la...

The mechanisms underlying heterozygosity-fitness correlations (HFCs) are subject of intense debates, especially about how important population features such as size or degree of isolation influence HFCs. Here, we report variation in HFCs between Large and Small populations of a self-compatible shrub (Myrtus communis) occurring within an...

Premise: Divergence of floral morphology and breeding systems are often expected to be linked to angiosperm diversification and environmental niche divergence. However, available evidence for such relationships remain idiosyncratic, due to different taxonomic, geographical and time scales. The Palearctic genus Helianthemum shows the highest...
