Abstract

The Pleistocene glaciations are considered as a major driving force of intraspecific divergence, diversification and speciation. During post-glacial recolonization, when reproductive isolation is incomplete and formerly isolated lineages meet as a result of range expansion at a secondary contact zone, further mating between the populations will produce hybrids, resulting in the formation of a hybrid zone, genetic introgression or reinforcement speciation through pre-zygotic isolation mechanisms. Sexual selection is well recognized for its important role in promoting pre-zygotic isolation through variation among former allopatric and sympatric populations in reproductive traits. This phenomenon may dramatically accentuate consequences of the climatic oscillations on species. Notwithstanding, the reproductive trait divergence has not been approached in the context of climatic oscillations. The aim of this paper is to investigate the phylogeography and geographical variation of a reproductive trait (male marking secretion, MMS) in the red-tailed bumblebee, Bombus lapidarius (L.) (Hymenoptera, Apidae) in order to compare the relation between the phylogeographic pattern and reproductive trait variation pattern. To manage our purpose, we use a phylogeographic approach based on five genes (nuclear and mitochondrial) and comparative chemical analyses of MMS. Our results show that Quaternary climatic oscillations have led to B. lapidarius population contraction in three main refugia (South Italy, Balkan, and Central-Eastern Europe). Populations from the South Italy refugium have experienced allopatric MMS differentiation and an incipient speciation process from another refugium. At the end of the Ice Age, Central-Eastern Europe and Balkan lineages have spread out of their refuge area. Central-Eastern Europe and South Italy have met in a secondary contact zone where our results suggest a reinforcement process on local MMS patterns.
