Genetic Diversity, Inbreeding Level, and Genetic Load in Endangered Snub-Nosed Monkeys (Rhinopithecus)

Frontiers in Genetics, 2020
The snub-nosed monkey genus (Rhinopithecus) comprises five closely related species (R. avunculus, R. bieti, R. brelichi, R. roxellana, and R. strykeri). All are among the world's rarest and most endangered primates. However, the genomic impact associated

Museomics Deciphers the Phylogeographic Differentiation and Conservation Status of a Montane Pheasant

Integrative Zoology, EarlyView.
Museum specimens provide a rich source of historical DNA, enabling insights into phylogenetic relationships and demographic history of the endangered Koklass Pheasant. Our findings uncovered a previously unrecognized population in Guizhou province and highlighted elevated extinction risk in populations from Anhui province and Southern China, informing ...

Impact of inbreeding on production, fertility, and health traits in German Holstein dairy cattle utilizing various inbreeding estimators

Journal of Dairy Science
: In dairy cattle production, it is important to understand how inbreeding affects production, fertility, and health traits. However, there is still limited use of genomic information to estimate inbreeding, despite advancements in genotyping ...

The Size, Demography, and Distribution of Cambodia's Largest Elephant Population Revealed Using Traditional Genetic Tools and a Novel SNP Panel

Integrative Zoology, EarlyView.
Asian elephant population parameters were assessed using microsatellite, SNP, and sex determination DNA markers. This represents one of the first studies in mainland Asia to demonstrate that integrating microsatellite and SNP data enhances genotyping success from degraded fecal samples, increases the number of useable samples and markers, and ...

An inbreeding perspective on the effectiveness of wildlife population defragmentation measures – a case study on wild boar (Sus scrofa) of Veluwe, The Netherlands

Frontiers in Ecology and Evolution
Pervasive inbreeding is a major genetic threat of population fragmentation and can undermine the efficacy of population connectivity measures. Nevertheless, few studies have evaluated whether wildlife crossings can alleviate the frequency and length of ...

Level of Inbreeding in Norik of Muran Horse: Pedigree vs. Genomic Data

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2019
The objective of this study was to analyse the level of pedigree and genomic inbreeding in a herd of the Norik of Muran horses. The pedigree file included 1374 animals (603 stallions and 771 mares), while the reference population consisted of animals ...

Genomic Investigations Unveil the Genetic Underpinnings of Environmental Adaptation in African Goat Populations

Integrative Zoology, EarlyView.
This study integrates genomics and landscape genetics to analyze African goat environmental adaptation. Analyzing 1591 samples, it finds population structure differentiates geographically into four groups, with gene flow between wild Yura goats and North Africans.

A genomic tale of inbreeding in western Mediterranean human populations

Human Genetics
Abstract Consanguineous marriages are common in many worldwide human populations, and the biological consequences for offspring can be relevant at the biomedical level. The current genomic revolution displayed through genome-wide studies is challenging the paradigm in the analysis of consanguinity.

Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities

Integrative Zoology, EarlyView.
Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.
