A unique and personal insight into the ecology and evolution of pollinators, their
relationships with flowers, and their conservation in a rapidly changing world. The …

Abstract The Strait of Gibraltar (SG) is reputed for being both a bridge and a geographic
barrier to biological exchanges between Europe and Africa. Major genetic breaks …

Background and Aims The underlying evolutionary processes of pollinator-driven floral
diversification are still poorly understood. According to the Grant–Stebbins model speciation …

The repeated transition from outcrossing to selfing is a key topic in evolutionary biology.
However, the molecular basis of such shifts has been rarely examined due to lack of …

Background Some species of long-spurred orchids achieve pollination by a close
association with long-tongued hawkmoths. Among them, several Habenaria species present …

Darwin proposed that the driving force for the evolution of style polymorphisms is the
promotion of cross‐pollination between style morphs, through accurate placement of pollen …

Different pollinators can exert different selective pressures on floral traits, depending on how
they fit with flowers, which should be reflected in the patterns of variation and covariation of …

Abstract Background and Aims Heterostyly and related style polymorphisms are suitable
model systems to evaluate the importance of functional pollinators in the maintenance of …

Many Neotropical tree species are widespread at continental and even inter-continental
scales, but phenotypic variation across their respective ranges has rarely been quantified …

Geographic pattern of phenotypic variation can appear in a clinal or a mosaic fashion and
can evidence adaptive or non-adaptive variation. To shed light on the mechanisms …
