Quaternary phylogeography: the roots of hybrid zonesGodfrey M Hewitt
Biological Sciences, UEA, Norwich, NR4 7TJ, UK
Genetica 139:617-38. 2011..Hybrid-zone roots are complex and deep, and considerations of their complexity can reveal evolutionary pathways of species. They are indeed windows on evolution...

School of Biological Sciences, University of East Anglia, Norwich, UK
BMC Biol 7:32. 2009..This spider persists in heterogeneous environments because of its ability to recolonise areas through active long-distance airborne dispersal using silk as a sail, in a process termed 'ballooning'... 
The genetic legacy of the Quaternary ice agesG Hewitt
School of Biological Sciences, University of East Anglia, Norwich, UK
Nature 405:907-13. 2000..The present genetic structure of populations, species and communities has been mainly formed by Quaternary ice ages, and genetic, fossil and physical data combined can greatly help our understanding of how organisms were so affected...- Genetic consequences of climatic oscillations in the QuaternaryG M Hewitt
School of Biological Sciences, University of East Anglia, Norwich NR4 7TJ, UK
Philos Trans R Soc Lond B Biol Sci 359:183-95; discussion 195. 2004..Our poor understanding of refugial biodiversity would benefit from further combined fossil and genetic studies... - Biodiversity: a climate for colonizationGodfrey M Hewitt

School of Biological Sciences, University of East Anglia, Norwich, UK
Syst Biol 53:711-34. 2004..Only 6 out of 24 cladogenetic events were associated with host switching, rendering geographical factors more important in recent diversification... - PhylogeographyBrent C Emerson
School of Biological Sciences, University of East Anglia, Norwich, UK
Curr Biol 15:R367-71. 2005 - European colonization by the spined loach (Cobitis taenia) from Ponto-Caspian refugia based on mitochondrial DNA variationMark A Culling

Centre for Ecology, Evolution and Conservation, School of Biological Sciences, University of East Anglia, Norwich NR4 7TJ, UK
Mol Ecol 15:517-27. 2006..We suggest that spiders present a useful opportunity for studying the effect of these sorts of bacteria on the evolution of host traits, such as those that are under sexual selection... - Apparent 'sympatric' speciation in ecologically similar herbivorous beetles facilitated by multiple colonizations of an islandBjarte H Jordal

Mol Ecol 12:563-84. 2003..This certainly will increase our ability to address more complex questions, and thereby the sophistication of genetic analyses of populations... - Comparison of substitution rates in ZFX and ZFY introns of sheep and goat related species supports the hypothesis of male-biased mutation ratesLori Jayne Lawson
School of Biological Sciences, University of East Anglia, Norwich NR4 7TJ, UK
J Mol Evol 54:54-61. 2002..Finally, there was no apparent evidence that these introns are subject to selective constraints, although low levels of intraspecific polymorphism reduce the power of neutrality tests...
