Population Genetics with Fluctuating Population Sizes
Standard neutral population genetics theory with a strictly fixed population size has important limitations. An alternative model that allows independently fluctuating population sizes and reproduces the standard neutral evolution is reviewed. We then study a situation such that the competing species are neutral at the equilibrium population size but population size fluctuations nevertheless fa...
متن کاملPopulation genetics of polymorphism and divergence under fluctuating selection.
Current methods for detecting fluctuating selection require time series data on genotype frequencies. Here, we propose an alternative approach that makes use of DNA polymorphism data from a sample of individuals collected at a single point in time. Our method uses classical diffusion approximations to model temporal fluctuations in the selection coefficients to find the expected distribution of...
متن کاملPopulation genetics data help to guide the conservation of palm species with small population sizes and fragmented habitats in Madagascar
BACKGROUND The need to incorporate genetic data into conservation management decisions is increasingly recognised. However, many published studies represent a 'gold standard' of sampling, techniques, and analyses. Such rigour is often not possible with limited funding and resourcing available for developing plans for the increasing number of threatened species requiring conservation management....
متن کاملPopulation genetics
Population genetics is the study of genetic variability within a population and of the forces that act upon it. As well as being of central importance to our understanding of evolution from prehistoric to modern times, it now also affects our everyday lives — whether considering human genetic disease, how to avoid the extinction of rare species or the merits of ‘DNA fingerprinting’ in forensic ...
