Effective Population Size

open access: yes, 2022
AbstractWe expect heterozygosity to be lost at a rate of 1/2N per generation in an ideal population because of genetic drift where N is the census population size. The effective size of a population is the size of the ideal (Wright–Fisher) population that will result in the same amount of genetic drift as in the actual population being considered ...

Effective population size in field pea. [PDF]

open access: yesBMC Genomics
Abstract Background Effective population size ( N e ) is a pivotal parameter in population genetics as it can provide information on the rate of inbreeding and the ...

Effective population size for culturally evolving traits. [PDF]

open access: yesPLoS Comput Biol, 2022
Population size has long been considered an important driver of cultural diversity and complexity. Results from population genetics, however, demonstrate that in populations with complex demographic structure or mode of inheritance, it is not the census ...

The Effective Size of a Subdivided Population [PDF]

open access: yesGenetics, 1997
This paper derives the long-term effective size, Ne, for a general model of population subdivision, allowing for differential deme fitness, variable emigration and immigration rates, extinction, colonization, and correlations across generations in these processes. We show that various long-term measures of Ne, are equivalent.

Host body size, not host population size, predicts genome-wide effective population size of parasites [PDF]

open access: yes, 2023
Funding was provided by US NSF DEB-1342604, DEB-1925487 and DEB-1926919 grant awards to K.P.J., and European Commission grant H2020-MSCA-IF-2019 (INTROSYM:886532) to JD.The effective population size (N-e) of an organism is expected to be generally ...

Effective population size [PDF]

open access: yesCurrent Biology, 2002
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.

Effective Population Size of Korean Populations [PDF]

open access: yesGenomics & Informatics, 2014
Recently, new methods have been developed for estimating the current and recent changes in effective population sizes. Based on the methods, the effective population sizes of Korean populations were estimated using data from the Korean Association Resource (KARE) project. The overall changes in the population sizes of the total populations were similar

The effective size of bryophyte populations

open access: yesJournal of Theoretical Biology, 2009
Bryophytes with their dominant haploid stage conform poorly to the life cycles generally treated in population genetical models. Here we make a detailed analysis of what effective sizes bryophyte model populations have as a function of their breeding system.

On Heterozygosity and the Effective Size of Populations Subject to Size Changes [PDF]

open access: yesEvolution, 1982
When a population is subject to fluctuations in size, the effective population number during any time interval is usually approximated by the harmonic mean of the successive generation sizes (Wright, 1938, 1939). If there are no mutations, the population will eventually reach complete homozygosity.

A large Plasmodium vivax reservoir and little population structure in the South Pacific [PDF]

open access: yes, 2013
The importance of Plasmodium vivax in malaria elimination is increasingly being recognized, yet little is known about its population size and population genetic structure in the South Pacific, an area that is the focus of intensified malaria control.; We
