AbstractIn swallowtail butterflies of the Papilio machaon species group, mitochondrial (mt) DNA divergence has allowed speciation and adaptation to be understood more precisely. The reconstructed phylogeny of mtDNA of the P. machaon group is largely congruent with prior systematic hypotheses based on allozymes and color pattern. Genetic divergences of mtDNA support use of broad, character-based species concepts for the P. machaon group, and allow inferences regarding the origin of hybrid populations. The mtDNA phylogeny provides a guide for evolutionarily appropriate comparisons in studies of the chemical and genetic basis of hostplant use. Finally, mtDNA demonstrates the phylogenetically distinct status of an endangered species, P. hospiton.

AbstractSyngnathus abaster is a euryhaline pipefish distributed in the Mediterranean, Black Sea, and the north-eastern Atlantic. Although its populations are characterised by high morphological plasticity, neither congruent information about the morphological differentiation of S. abaster populations from the Mediterranean lagoons is available, nor population genetic surveys have been so far performed. In this context, the aims of our study were as follow: i) to describe the variation at nine meristic characters of S. abaster from two western Mediterranean brackish-water areas: the Tunis north lagoon (Tunisia) and the Mauguio lagoon (France); ii) to analyse sequences of four mitochondrial DNA regions in order to evaluate the occurrence of genetic variation between the two areas, if any. The morphological survey revealed a subdivision into two distinct groups: the first included the Tunisian specimens, the second the French ones. Genetic analysis evidenced the occurrence of a sharp genetic structuring with high levels of genetic differentiation between Tunisian and French S. abaster populations. Results suggest that the evolutionary forces driven by the different biogeographical and ecological conditions of the two Mediterranean brackish-water areas have boosted the morphological and genetic divergence of the populations here analysed. The scarce potential of long-distance dispersal of S. abaster may have also enhanced the divergence retrieved.
