Evaluating loci for use in the genetic analysis of population structure
- M. Beaumont, R. Nichols

It is suggested that genetic variation at a discrepant locus, Identified under these conditions, is likely to have been influenced by natural selection, either acting on the locus itself or at a closely linked locus.
Hybridization and speciation
A perspective on the context and evolutionary significance of hybridization during speciation is offered, highlighting issues of current interest and debate and suggesting that the Dobzhansky–Muller model of hybrid incompatibilities requires a broader interpretation.
A method for quantifying differentiation between populations at multi-allelic loci and its implications for investigating identity and paternity
- D. Balding, R. Nichols
- BiologyGenetica
- 2005
A method is proposed for allowing for the effects of population differentiation, and other factors, in forensic inference based on DNA profiles, which is currently used in some UK courts and has important advantages over the ‘Ceiling Principle’ method, which has been criticized on a number of grounds.
Interpreting DNA Evidence: Statistical Genetics for Forensic Scientists
- R. Nichols
- BiologyHeredity
- 1 May 1999
This collection of 17 wide-ranging articles shows the remarkable applicability of molecular approaches to many aspects of ecology and evolution and cannot be used as a core text for teaching molecular Ecology and evolution, but will be genuinely useful for supplementary reading.

Spatial patterns of genetic variation generated by different forms of dispersal during range expansion
- K. Ibrahim, R. Nichols, G. Hewitt
- Environmental ScienceHeredity
- 1 September 1996
It is shown how the three forms of dispersal during colonization bring about contrasting population genetic structures and how this affects estimates of gene flow.
The persistence of Pliocene populations through the Pleistocene climatic cycles: evidence from the phylogeography of an Iberian lizard
- O. Paulo, C. Dias, M. Bruford, W. Jordan, R. Nichols
- BiologyProceedings of the Royal Society of London…
- 7 August 2001
The evidence suggests that earlier events in the Pliocene initiated the main divergence between populations in the Iberian lizard Lacerta schreiberi, and implies that the different populations survived through the Pleistocene in separate localities.
The role of vicariance vs. dispersal in shaping genetic patterns in ocellated lizard species in the western Mediterranean
- O. Paulo, J. Pinheiro, A. Miraldo, M. Bruford, W. Jordan, R. Nichols
- Environmental Science, BiologyMolecular Ecology
- 1 March 2008
The results suggest that the MSC may have played a much less important role in shaping the current western Mediterranean biogeographical patterns than might have been anticipated from the dramatic nature of the episode.
Phylogenetic Analysis of Varicella-Zoster Virus: Evidence of Intercontinental Spread of Genotypes and Recombination
- Winsome Barrett Muir, R. Nichols, J. Breuer
- BiologyJournal of Virology
- 15 February 2002
A heteroduplex mobility assay was used to identify variants of varicella-zoster virus circulating in the United Kingdom and elsewhere, and extensive genetic correlation between widely spaced sites indicated that recombination has been rare.
Estimating the Number of Subpopulations (K) in Structured Populations
- R. Verity, R. Nichols
- Computer ScienceGenetics
- 10 June 2016
It is found that TI can be used to obtain estimates of the model evidence that are more accurate and precise than those based on heuristics, and estimates of K based on these values are found to be more reliable than thosebased on a suite of model comparison statistics.
