Effective population size [PDF]

Current 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.

Estimation of Population-Specific Genetic Parameters Important for Long-Term Optimum Contribution Selection—Case Study on a Dairy Istrian Sheep Breed

Animals, 2021
The Istrian sheep breed has been subjected to selection for dairy traits for more than two decades. However, a detailed study of some important population-specific parameters such as effective population size (Ne) and connectedness between flocks has ...

Demographic resilience of brook trout populations subjected to experimental size‐selective harvesting

Evolutionary Applications, 2022
Sustainable management of exploited populations benefits from integrating demographic and genetic considerations into assessments, as both play a role in determining harvest yields and population persistence.

Estimates of Effective Population Size in Commercial and Hatchery Strains of Coho Salmon (Oncorhynchus kisutch (Walbaum, 1792))

Animals, 2022
Understanding the genetic status of aquaculture strains is essential for developing management guidelines aimed at sustaining the rates of genetic gain for economically important traits, as well as securing populations that will be robust to climate ...

Population structure and inbreeding of Holstein cattle in southern Brazil

Revista Brasileira de Zootecnia, 2020
The present investigation aimed to evaluate the population structure and inbreeding of Holstein herds in southern Brazil. To carry out the analysis, the Associação Paranaense de Criadores de Bovinos da Raça Holandesa (APCBRH) in Brazil provided the data,

Pacific salmon and the coalescent effective population size. [PDF]

PLoS ONE, 2010
Pacific salmon include several species that are both commercially important and endangered. Understanding the causes of loss in genetic variation is essential for designing better conservation strategies.

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

Evolution, 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]

, 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

Long-term dynamics of morphogenetic indicators of the terrestrial mollusk Cepaea vindobonensis (Gastropoda, Pulmonata, Helicidae) in the Bekaryukovsky Bor Natural Monument, Russia

Nature Conservation Research: Заповедная наука, 2021
Cepaea vindobonensis (Gastropoda, Pulmonata, Helicidae) is a terrestrial mollusk, protected in the Belgorod Region (European Russia). In the Bekaryukovsky Bor Natural Monument, its peripheral population is known considering to be one of the most abundant

Multiple merger coalescent inference of effective population size. [PDF]

Philos Trans R Soc Lond B Biol Sci
Variation in a sample of molecular sequence data informs about the past evolutionary history of the sample\u27s population. Traditionally, Bayesian modeling coupled with the standard coalescent, is used to infer the sample\u27s bifurcating genealogy and ...
