Mating schemes for optimum contribution selection with constrained rates of inbreeding

Genetics Selection Evolution, 2000
The effect of non-random mating on genetic response was compared for populations with discrete generations. Mating followed a selection step where the average coancestry of selected animals was constrained, while genetic response was maximised.

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.

Estimation of coancestry in Iberian pigs using molecular markers

Conservation Genetics, 2002
Genetic markers provide a useful tool to estimate pairwise coancestry between individuals in the absence of a known pedigree. In the present work 62 pigs from two related strains of Iberian breed, Guadyerbas and Torbiscal, belonging to a conservation programme with completely known pedigrees since 1945, have been genotyped for 49 microsatellites.

Advantages of using molecular coancestry in the removal of introgressed genetic material [PDF]

Genetics Selection Evolution, 2013
When introgression of undesired exogenous genetic material occurs in a population intended to remain pure, actions are necessary to recover the original background. It has been shown that genome-wide information can replace pedigree information for different objectives and is a valuable tool in the fields of genetic conservation and breeding.

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.

Global population divergence and admixture of the brown rat (Rattus norvegicus) [PDF]

, 2016
Native to China and Mongolia, the brown rat (Rattus norvegicus) now enjoys a worldwide distribution. While black rats and the house mouse tracked the regional development of human agricultural settlements, brown rats did not appear in Europe until the ...

Combining Multiple Genetic Estimates of Ne

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Researchers often use multiple genetic methods to estimate contemporary effective population size (Ne), but few formally combine estimates despite potential benefits for increasing precision. Maximising benefits requires an optimal, inverse‐variance weighting scheme.

Supercolonial structure of invasive populations of the tawny crazy ant Nylanderia fulva in the US [PDF]

, 2018
Background: Social insects are among the most serious invasive pests in the world, particularly successful at monopolizing environmental resources to outcompete native species and achieve ecological dominance.

Pedigree Analysis of Modern Muscadine Cultivars Reveals a Narrow Genetic Base

Journal of the American Society for Horticultural Science, 2023
Muscadine grape (Vitis rotundifolia var. rotundifolia) is a rare crop in that it has transitioned from a wild fruiting plant to a domesticated fruit within the past 150 years.

Microhaplotype Methods Enable Relationship Inference in a Bottlenecked Mammalian Species

Animal Conservation, Volume 29, Issue 2, Page 136-145, April 2026.
Northern elephant seals (Mirounga angustirostris) are among the most genetically depauperate mammals in the world. A near‐total population bottleneck in the 19th century, coupled with the breeding system of extreme polygyny, has challenged efforts to estimate individual reproductive success with genetic methods.
