| host generalists and specialists emerging side by side: an analysis of evolutionary patterns in the cosmopolitan chewing louse genus menacanthus. | parasites with wide host spectra provide opportunities to study the ecological parameters of speciation, as well as the process of the evolution of host specificity. the speciose and cosmopolitan louse genus menacanthus comprises both multi-host and specialised species, allowing exploration of the ecological and historical factors affecting the evolution of parasites using a comparative approach. we used phylogenetic analysis to reconstruct evolutionary relationships in 14 species of menacanthus ... | 2015 | 25311782 |
