| recovering the evolutionary history of crowned pigeons (columbidae: goura): implications for the biogeography and conservation of new guinean lowland birds. | assessing the relative contributions of immigration and diversification into the buildup of species diversity is key to understanding the role of historical processes in driving biogeographical and diversification patterns in species-rich regions. here, we investigated how colonization, in situ speciation, and extinction history may have generated the present-day distribution and diversity of goura crowned pigeons (columbidae), a group of large forest-dwelling pigeons comprising four recognized ... | 2018 | 29199106 |
