Ecology 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 ...

The Effective Size of a Subdivided Population [PDF]
Genetics, 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.

Walailak Journal of Science and Technology, 2021 The population structure of a fruit fly, Zeugodacus tau, was studied by a Single-Strand Conformation Polymorphism (SSCP) technique. Twenty haplotypes of Cytochrome Oxidase unit I (COI) sequence were found in flies collected from Southern Thailand.

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

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

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 ...

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.

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.

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,
