Harvest‐induced evolution and effective population size
Much has been written about fishery-induced evolution (FIE) in exploited species, but relatively little attention has been paid to the consequences for one of the most important parameters in evolutionary biology-effective population size (N e). We use a combination of simulations of Atlantic cod populations experiencing harvest, artificial manipulation of cod life tables, and analytical method...
متن کاملAdaptive evolution and effective population size in wild house mice.
Estimates of the proportion of amino acid substitutions that have been fixed by selection (α) vary widely among taxa, ranging from zero in humans to over 50% in Drosophila. This wide range may reflect differences in the efficacy of selection due to differences in the effective population size (N(e)). However, most comparisons have been made among distantly related organisms that differ not only...
متن کاملThe Role of the Effective Population Size in Compensatory Evolution
The impact of the effective population size (Ne) on the efficacy of selection has been the focus of many theoretical and empirical studies over the recent years. Yet, the effect of Ne on evolution under epistatic fitness interactions is not well understood. In this study, we compare selective constraints at independently evolving (unpaired) and coevolving (paired) sites in orthologous transfer ...
متن کاملFractal Population Ecology Theory
Abstract Purpose - The aim of this paper is to describe the population ecology theory through fractal thinking, an emergent human operating system that is creative, adaptive, healthy, and evolutionary; furthermore, a parallel is drawn between the population ecology model and the fractal structure. Top-down hierarchies are typically characterized by command and control systems of the authority t...
متن کاملEffective population size
What is it? An aid to calculation in population genetics, introduced by Sewall Wright. The rate of change of the genetic make-up of a population by genetic drift — fluctuations in allele frequencies caused by random sampling — is inversely related to the effective population size, Ne. Ne is measured with reference to an ideal ‘Wright–Fisher’ population. This has a fixed number of N diploid bree...
