Reconciling supertramps, great speciators and relict species with the taxon cycle stages of a large island radiation (Aves: Campephagidae)

Aim: The taxon cycle concept provides a geographically explicit and testable set of hypotheses for exploring the evolutionary processes underlying the distribution of species in space and time. Here, we test taxon cycle predictions within a large avian island radiation, the core Campephagidae and explicitly integrate the concepts of ‘supertramps’, ‘great speciators’ and relictualization.
Location: The Indo-Pacific, Australia, Asia and Africa.
Taxon: Corvoid passerine birds.
Methods: We constructed a new time-calibrated molecular phylogeny of the core Campephagidae (cuckoo-shrikes, cicadabirds and trillers) using Bayesian phylogenetic methods. Ancestral range estimation methods and diversification rate analyses were used to explore the dispersal and diversification history of the group. We used an extensive dataset on wing morphology and range distributions to test for correlations between evolutionary age of species and dispersal capacity, diversification and distribution, while account..., Campephagidae alignmentSee details in Table S1.1 in Appendix S1 in the online Supporting Information.Pepke_etal_2019_Campephagidae_align.PAUCampephagidae alignment txtSee details in Table S1.1 in Appendix S1 in the online Supporting Information.Pepke_etal_2019_Campephagidae_align.PAU.txt,
