Aim We compare different scenarios for the origin of the endemic western Mediterranean species of aquatic Coleoptera of the “Haenydra” lineage (Hydraenidae, Hydraena) through contrasting predictions of the relationship between their phylogenetic and geographic distance. We test whether species originated 1) through successive periods of dispersal and speciation, or through fragmentation of the ...

The seeds of many plant species present a food body that is consumed by animal dispersers. In theory, if the animals are polyphagous, the availability of alternative food resource other than the diaspore itself may influence its dispersal and survival. We used the myrmecochore Helleborus foetidus L. (Ranunculaceae), the seeds ofwhich are attached to a lipid-rich elaiosome that is attractive to ...
