- 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...

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
Department of Zoology and Biodiversity Research Centre, University of British Columbia, Vancouver, BC, Canada V6T 1Z4
Proc Natl Acad Sci U S A 106:21737-42. 2009..In contrast to mammals, the direction of traffic across the land bridge in birds was primarily south to north. The event transformed the tropical avifauna of the New World...
- GEIGER: investigating evolutionary radiationsLuke J Harmon
Department of Biological Sciences, University of Idaho, Moscow, ID 83844, USA
Bioinformatics 24:129-31. 2008..GEIGER can carry out simulations, parameter estimation and statistical hypothesis testing. Additionally, GEIGER's simulation algorithms can be used to analyze the statistical power of comparative approaches...
