| This package estimates the effective sizes from actual to ancestral time with a coalescent approach. It works on steps of constant size to resolve the probabilities by an approximation of maximum likelihood from a Bayesian posterior distribution. This package works with R software version 3.0.2 or later for VAREFF version 1.1 and R software version 2.10.0 or later for VAREFF version 1.0. This new version contains a new function TMRCA to estimate the time of the detected bottleneck. |

| Understanding and predicting population abundance is a major challenge confronting scientists. Several genetic models have been developed using microsatellite markers to estimate the present and ancestral effective population sizes. However, to get an overview on the evolution of population requires that past fluctuation of population size be traceable. To address the question, we developed a new model estimating the past changes of effective population size from microsatellite by resolving coalescence theory and using approximate likelihoods in a Monte Carlo Markov Chain approach. The efficiency of the model and its sensitivity to gene flow and to assumptions on the mutational process were checked using simulated data and analysis. The model was found... |
