When you click on the link below, you will obtain a list of directories.

When you click on the directory you will get a file listing and some explanatory text. (which you can also download: its in the read_me file).

The directories

• Mauritian skinks: Data from endangered skinks from the islets around Mauritius.  The data are Excel files as genotypes.  These data were analysed in manuscript in press in Molecular Ecology (2004) using the software below.
• Bayallele: a method to obtain estimates of population size, migration rates and mutation rates from microsatellite (and allozyme etc) allelele frequencies in each population.  It requires the user to specify prior beliefs about the population sizes migration and mutation rates.  The software is being developed for release (April 2004) with a user-friendly front end here.  Impatient Pascal programmers might want to make use of the original code and example input file in the above directory.
• Mauritius kestrel: microsatellite data from Museum skins from Mauritius, present-day populations of kestrels on Mauritius, the Seychelles, Madagascar and related continental species. The data are in Excel files either in two formats: genotype data and allele frequencies. This data is analyzed in a paper by  Nichols et al 2001 MOL ECOL 10 (3): 593-602. and Groombridge et. al. 1999.  NATURE 403 (6770): 616-616 FEB 10 2000.
• Further details on Culex genetics. This directory contains tables giving allele frequencies from populations in the London Underground and nearby populations on the surface. Details of allozyme scoring are also given. These tables are intend to augment the Heredity paper: Byrne & Nichols 1998. Culex mosquitoes in the London Underground. The tables are in Word format, and RTF (rich text format).
• Fst likelihoods: programs to calculate likelhood curves for Fst from genetic data. The programs are available as executable files for PCs (*.exe files) and as Turbo Pascal source files.
• Heterozygosity likelihoods: programs to calculate likelhood curves for heterozygosity from genetic data. The programs are available as executable files for PCs (*.exe files) and as Turbo Pascal source files.  The output can be used to estimate the relative size of populations if the same loci are scored in each population.  The method is outlined in  Nichols RA, Bruford MW, Groombridge JJ  Sustaining genetic variation in a small population: evidence from the Mauritius kestrel.  MOL ECOL 10 (3): 593-602 MAR 2001.
• Beaumont_Nichols programs to evaluate differences in Fst estimates obtained from different loci as described in Beaumont & Nichols(1996), Proc.Roy.Soc.B263:1619-1626. They are available as C code.
