Zoology Department and Centre for Biodiversity Research, University of British Columbia, Vancouver, British Columbia, Canada
PLoS ONE 3:e1907. 2008..Although further replication of the trends reported here is required, the results suggest that dimensionality of selection may complement genetic and geographic explanations for the degree of diversification in nature...
Heterogeneous genomic differentiation between walking-stick ecotypes: "isolation by adaptation" and multiple roles for divergent selectionPatrik Nosil
Department of Zoology, University of British Columbia, Vancouver, BC, Canada

Am Nat 169:151-62. 2007..cristinae ecotypes is incomplete, and so only the stages before the completion of speciation have been examined.

Ann N Y Acad Sci 1206:110-29. 2010..The study of gene expression has promise for increasing our understanding ecological speciation, particularly when integrative approaches are applied... - Ecological explanations for (incomplete) speciationPatrik Nosil
Zoology Department and Biodiversity Research Centre, University of British Columbia, Vancouver, BC, Canada
Trends Ecol Evol 24:145-56. 2009..However, evidence for each selective hypothesis is still scarce, and further work is required to determine their relative importance... - Natural selection in populations subject to a migration loadDaniel I Bolnick
Section of Integrative Biology, University of Texas at Austin, Austin, Texas 78712, USA
Evolution 61:2229-43. 2007..However, we also find evidence that recurrent adult migration between parapatric populations may tend to obscure the effects of selection... - Frequency-dependent selection: when being different makes you not stand outPatrik Nosil

Curr Biol 16:R806-8. 2006..Fitness advantages to rare genotypes may help maintain variation within populations, but the mechanisms underlying these advantages require further study... - Experimental evidence that predation promotes divergence in adaptive radiationPatrik Nosil
Department of Biological Sciences, Simon Fraser University, Burnaby, BC, Canada V5A 1S6
Proc Natl Acad Sci U S A 103:9090-5. 2006..Our results indicate that both competition and predation may commonly serve as mechanisms of adaptive radiation... - Ecological divergence promotes the evolution of cryptic reproductive isolationPatrik Nosil

Proc Natl Acad Sci U S A 103:3209-13. 2006..These findings are highly consistent with the hypothesis that ecological adaptation plays a fundamental and taxonomically general role in promoting reproductive isolation and speciation... - Perspective: Reproductive isolation caused by natural selection against immigrants from divergent habitatsPatrik Nosil
Department of Biosciences, Behavioural Ecology Research Group, Simon Fraser University, Burnaby, British Columbia V5A 1S6, Canada
Evolution 59:705-19. 2005..We hope that the formal recognition of immigrant inviability and our demonstration of its evolutionary importance will stimulate more explicit empirical studies of its contributions to speciation... - Reproductive isolation caused by visual predation on migrants between divergent environmentsPatrik Nosil
Department of Biosciences, Behavioural Ecology Research Group, Simon Fraser University, Burnaby, British Columbia V5A 1S6, Canada
