Ice sheets promote speciation in boreal birdsJason T Weir
Department of Zoology, University of British Columbia, Vancouver, V6T 1Z4, Canada
Proc Biol Sci 271:1881-7. 2004..One explanation for the absence of pre-Pleistocene superspecies in boreal avifaunas is that strong selection pressures operated in boreal refugia, causing superspecies members to achieve ecological differentiation at an accelerated rate...
Divergent timing and patterns of species accumulation in lowland and highland neotropical birdsJason T Weir
Department of Zoology, University of British Columbia, Vancouver, British Columbia V6T 1Z4, Canada
Evolution 60:842-55. 2006..This increase resulted in a fauna with one third of its species dating to the last one million years...
The latitudinal gradient in recent speciation and extinction rates of birds and mammalsJason T Weir
Biodiversity Research Center and Department of Zoology, University of British Columbia, Vancouver, BC V6T 1Z4, Canada
Science 315:1574-6. 2007..Instead, our findings suggest that faster turnover at high latitudes contributes to the latitudinal diversity gradient...
The Great American Biotic Interchange in birdsJason T Weir
