This note summarizes developments of the genepop software since its first description in 1995, and particular those new to version 4.0: an extended input format, several estimators neighbourhood size under isolation by distance, confidence intervals for null allele frequency, less important extensions previous options. now runs Linux as well Windows, can be entirely controlled batch calls.
I reexamine the use of isolation by distance models as a basis for estimation demographic parameters from measures population subdivision. To that aim, first provide results values F-statistics in one-dimensional and coalescence times two-dimensional models, make more precise earlier models. Based on these results, propose method data analysis involving regression FST/(1-FST) estimates pairs subpopulations geographic populations along linear habitats or logarithm habitats. This provides...

We examine the power of different exact tests differentiation for diploid populations. Since there is not necessarily random mating within populations, appropriate hypothesis to construct that independent sampling genotypes. There are two categories tests, FST-estimator and goodness fit tests. In this latter category, we distinguish “allelic statistics”, which account nature alleles genotypes, from “genotypic statistics” do not. show allelic similar when balanced, higher than genotypic When...
Wolbachia are a group of intracellular inherited bacteria that infect wide range arthropods. They associated with number different reproductive phenotypes in their hosts, such as cytoplasmic incompatibility, parthenogenesis and feminization. While it is known the bacterial strains responsible for these host form single clade within α–Proteobacteria, until now has not been possible to resolve evolutionary relationships between differentWolbachia strains. To address this issue we have cloned...
Currently used tests of Hardy-Weinberg proportions do not take into account the nature alternative hypothesis, which is generally a heterozygote deficiency. Different exact tests, appropriate for small sample size and large number alleles, are proposed in this perspective, their properties evaluated by power comparisons. Some found to be close optimal detection inbreeding or excess, one score test closely related Robertson Hill's estimator coefficient. This also easily applied multiple...
Abstract I describe a method of analysis genetic differentiation which is suitable for the comparison and demographic estimates ‘neighborhood size’– more precisely product density second moment dispersal distance σ2– in continuous populations sampled at smallest scale. This based on results models isolation by common to wide variety distances.

Summary The simple and partial Mantel tests are routinely used in many areas of evolutionary biology to assess the significance association between two or more matrices distances relative same pairs individuals demes. Partial rather than widely relationship variables displaying some form structure. We show that contrary a shared belief, not valid this case, their bias remains close test. confirm strong biases expected under sampling design spatial correlation parameter drawn from an actual...
A comparative study between microsatellite and allozyme markers was conducted on natural populations of resident brown trout (Salmo trutta) sampled over a reduced geographical scale hatchery strains. The higher level polymorphism observed at loci resulted in power statistical tests for differentiation among population samples genotypic linkage disequilibrium. Genetic distances Cavalli-Sforza Edwards were average two times larger microsatellites than allozymes but multilocus FST estimates...
Rickettsia-like maternally inherited bacteria have been shown to be involved in a variety of alterations arthropod sexuality, such as female-biased sex ratios, parthenogenesis, and sterility crosses either between infected males uninfected females or individuals (cytoplasmic incompatibility). We characterized several these microorganisms through partial sequences the small (16S) large (23S) subunit ribosomal DNA. All symbionts identified, which include cytoplasmic incompatibility...
Abstract Expected values of Wright'sF-statistics are functions probabilities identity in state. These may be quite different under an infinite allele model and stepwise mutation processes such as those occurring at microsatellite loci. However, a relationship between the probability state models distribution coalescence times can deduced from by descent times. The FIS FST computed using this property. Examination conditional given some time also useful for explaining properties high rate...
Wolbachia are intracellular microorganisms that form maternally-inherited infections within numerous arthropod species. These bacteria have drawn much attention, due in part to the reproductive alterations they induce their hosts including cytoplasmic incompatibility (CI), feminization and parthenogenesis. Although Wolbachia's presence insect tissues has been well described, relatively few studies examined extent which infects other tissues. We tissue tropism a number of representative by...
Spatial autocorrelation is a well‐recognized concern for observational data in general, and more specifically spatial ecology. Generalized linear mixed models (GLMMs) with spatially autocorrelated random effects are potential general framework handling these correlations. However, as the result of statistical practical issues, such GLMMs have been fitted through undocumented use procedures based on penalized quasi‐likelihood approximations (PQL), under restrictive correlation. Alternatively,...
Abstract The analysis of kin selection in subdivided populations has been hampered by the lack well-defined measures genealogical relatedness presence localized dispersal. Furthermore, usual arguments underlying definition game-theoretical inclusive fitness are not exact under We define such to give first-order effects on probability fixation an allele. derived and valid finite For infinite island model, resulting measure is equivalent a previously used measure.

Partial Mantel tests were designed to test for correlation among three matrices of pairwise distances. We show through an example that these may be inadequate, because the associated P-value is not indicative type I error.
Maternally inherited bacteria of the genus Wolbachia are responsible for early death embryos in crosses between uninfected females and infected males several insect species. This phenomenon, known as cytoplasmic incompatibility, also occurs strains by different symbionts some species, including Drosophila simulans. was found two species closely related to D. simulans, mauritiana, sechellia, shown cause incompatibility latter but not mauritiana.

Recent papers have promoted the view that model-based methods in general, and those based on Approximate Bayesian Computation (ABC) particular, are flawed a number of ways, therefore inappropriate for analysis phylogeographic data. These further argue Nested Clade Phylogeographic Analysis (NCPA) offers best approach statistical phylogeography. In order to remove confusion misconceptions introduced by these papers, we justify explain reasoning behind inference. We ABC is statistically valid...
