Maintenance of genetic diversity in subdivided populations using genomic coancestry matrices

Molecular Ecology Resources, 2023
AbstractFor both undivided and subdivided populations, the consensus method to maintain genetic diversity is the Optimal Contribution (OC) method. For subdivided populations, this method determines the optimal contribution of each candidate to each subpopulation to maximize global genetic diversity (which implicitly optimizes migration between ...

Population Genomics Reveals Genetic Diversity, Introgression, and Genetic Differentiation in Tianshan Mountains Western Honeybees (Apis mellifera)

Evolutionary Applications, Volume 19, Issue 5, May 2026.
ABSTRACT The Tianshan Mountains, which host two native subspecies of western honeybees, represent the easternmost natural distribution limit of Apis mellifera. The managed Xinjiang black honeybee (XJ), introduced a century ago and designated as a Chinese National Animal Genetic Resource, has expanded rapidly under anthropogenic management.

Management of genetic diversity in small farm animal populations*

Animal, 2011
Many local breeds of farm animals have small populations and, consequently, are highly endangered. The correct genetic management of such populations is crucial for their survival.

Minimising Risks of Reduced Genetic Diversity in Marine Restoration

Evolutionary Applications, Volume 19, Issue 5, May 2026.
ABSTRACT Marine habitat restoration is expanding globally and increasingly relies on aquaculture and hatchery‐based propagation, yet the genetic consequences of producing and outplanting large numbers of habitat‐forming organisms remain poorly evaluated.

Effect of non-random mating on genomic and BLUP selection schemes

Genetics Selection Evolution, 2012
Background The risk of long-term unequal contribution of mating pairs to the gene pool is that deleterious recessive genes can be expressed. Such consequences could be alleviated by appropriately designing and optimizing breeding schemes i.e.

Detecting linkage between a trait and a marker in a random mating population without pedigree record. [PDF]

PLoS ONE, 2009
Modern linkage-based approaches employing extended pedigrees are becoming powerful tools for localizing complex quantitative trait loci. For these linkage mapping methods, it is necessary to reconstruct extended pedigrees which include living individuals,

Challenges of Introgression in Conservation: Genetic Diversity of the Endangered Wild Camel (Camelus ferus) in Mongolia

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Using non‐invasive nuclear and mitochondrial analysis, this study reveals evidence of introgression in critically endangered Wild Camels (Camelus ferus) from the domestic Bactrian camel (Camelus bactrianus), alongside reduced genetic diversity and higher inbreeding in both in situ and ex situ populations in Mongolia.

Evidence of Population Fragmentation of the Western European Hedgehog Erinaceus europaeus in Urban Landscapes

Ecology and Evolution, Volume 16, Issue 4, April 2026.
The Western European hedgehog (Erinaceus europaeus) is a declining mammal increasingly associated with urban landscapes. This study uses 1413 SNP markers to investigate the species' genetic structure and connectivity in Greater London, UK, and surrounding areas.
