Estimates of recent and historical effective population size in turbot, seabream, seabass and carp selective breeding programmes

open access: yesGenetics Selection Evolution, 2021
The high fecundity of fish species allows intense selection to be practised and therefore leads to fast genetic gains. Based on this, numerous selective breeding programmes have been started in Europe in the last decades, but in general, little is known ...

Calculation of the effective population size and estimating of total population size using mitochondrial DNA sequencing in Hamedan, Qazvin and Zanjan provinces [PDF]

open access: yesمجله بیوتکنولوژی کشاورزی, 2015
Although wolves have the ability to live in different habitat types, in recent years their population has been drastically reduced in most parts of the country and in some areas has become extinct.

An empirical examination of sample size effects on population demographic estimates in birds using single nucleotide polymorphism (SNP) data [PDF]

open access: yesPeerJ, 2020
Sample size is a critical aspect of study design in population genomics research, yet few empirical studies have examined the impacts of small sample sizes.

Effective number of white shark (Carcharodon carcharias, Linnaeus) breeders is stable over four successive years in the population adjacent to eastern Australia and New Zealand

open access: yesEcology and Evolution, 2021
Population size is a central parameter for conservation; however, monitoring abundance is often problematic for threatened marine species. Despite substantial investment in research, many marine species remain data‐poor presenting barriers to the ...

Navigating the temporal continuum of effective population size

open access: yes, 2021
Effective population size, Ne, is a key evolutionary parameter that determines the levels of genetic variation and efficacy of selection. Estimation and interpretation of Ne are essential in diverse areas of evolutionary and conservation biology, ranging

Effective population size in Busha and Gatačko cattle from Herzegovina: Ecological and molecular approach [PDF]

open access: yesAgroznanje, 2013
The effective population size (Ne) is one of basic core concepts in population genetics. Monitoring the effective population size, which is parallel to monitoring genetic variability, is of importance to population genetic studies and is applicable in ...

Effect of genomic selection on rate of inbreeding and coancestry and effective population size of Holstein and Jersey cattle populations.

open access: yesJournal of Dairy Science, 2020
Genetic diversity in livestock populations is a significant contributor to the sustainability of animal production. Also, genetic diversity allows animal production to become more responsive to environmental changes and market demands.

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

open access: yesAnimals, 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 ...

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.

Pedigree analysis of Santa Inês sheep and inbreeding effects on performance traits

open access: yesRevista Mexicana de Ciencias Pecuarias, 2020
Population parameters such as effective population size and coefficients of inbreeding are important information of a population but have rarely been studied in Santa Inês sheep.
