Management of genetic diversity of subdivided populations in conservation programmes (2010, background): “…by the initial number of alleles (James 1970; Hill and Rasbash 1986) and, because it is more sensitive to bottlenecks than expected heterozygosity, it reflects better past fluctuations in population size (Nei et al. 1975; Allendorf 1986; Cornuet and Luikart 1996; Luikart et al. 1998; Leberg 2002).”
The effects of sample size on population genetic diversity estimates in song sparrows Melospiza melodia (2008, methodology): “One way to alleviate this problem is through rarefaction to the smallest sample size (Petit et al. 1998, Leberg 2002, Kalinowski 2004).”
GENCLONE : a computer program to analyse genotypic data, test for clonality and describe spatial clonal organization (2006, methodology): “This is an alternative to the bootstrap, and to the rarefaction procedure (El Mousadik & Petit 1996), commonly used to compare the levels of diversity among sample sets of unequal size, and can also be used to compare allelic richness and heterozygosity in nonclonal organisms (Leberg 2002).”
Genetic differentiation and secondary contact zone in the seagrass Cymodocea nodosa across the Mediterranean–Atlantic transition region (2008, methodology): “The number of genets found at each site was standardized to 10 by multiple random reduction (Leberg, 2002), for interpopulation comparisons of estimates of allelic richness (Â), the average number of alleles per locus in each population.”
Estimating allelic richness and its diversity (2006, background): “Accumulation curves may also by drawn by computer simulations (Leberg, 2002), but this require an evolutionary model, rather difficult to establish in most cases.”
Standardizing methods to address clonality in population studies (2007, methodology): “As proposed for species richness S, the rarefaction method used to compare allelic richness estimates (Petit et al. 1998) or a permutation approach should be used (Leberg 2002) to compare two samples differing in sample size, n and N > n.”
hp-rare 1.0: a computer program for performing rarefaction on measures of allelic richness (2005, methodology): “Rarefaction is an infrequently used statistical method that accounts for this effect to produce unbiased estimates of allelic richness (Hurlbert 1971; Smith & Grassle 1977; Leberg 2002).”
Counting Alleles with Rarefaction: Private Alleles and Hierarchical Sampling Designs (2004, methodology): “Formulae have also been developed for calculating the sampling variance of the number of alleles in samples of g genes taken from the complete sample (Heck et al. 1975), a quantity that Leberg (2002) estimated by simulation.”
Patterns of Genetic Diversity and Its Loss in Mammalian Populations (2005, background): “Because heterozygosity is less likely than allelic diversity to be influenced by variation in sample sizes (Leberg 2002) or geographic range over which samples are collected, heterozygosity is often used as a measure for contrasting genetic diversity across studies.”
